Distribución espacio-temporal de aves acuáticas de la familia Laridae en un humedal costero sudamericano / Spatio-temporal distribution of aquatic birds of the family Laridae in a South American coastal wetland

Resumen Introducción: El humedal costero Poza de La Arenilla (HCPA), Callao, Perú, es un hábitat importante para el descanso y reposo de aves acuáticas, entre ellas la familia Laridae. Sin embargo, el humedal está sufriendo una degradación crítica debido al desarrollo de actividades antropogénicas. Objetivo: Evaluar la distribución espacio-temporal de las aves acuáticas de la familia Laridae reportadas en HCPA según la temporada del año entre 2013 y 2018. Métodos: Se realizaron muestreos quincenales en 11 zonas delimitadas de HCPA de enero 2013 a diciembre 2018, durante la mañana y la tarde, mediante el método de recuento total. Resultados: Se registraron 12 especies de la familia Laridae. Leucophaeus pipixcan fue la especie de mayor dominancia en la mayoría de las zonas estudiadas y su presencia se destaca en verano y primavera. Las especies con mayor distribución en el humedal son L. pipixcan, Larus dominicanus y Larus belcheri, que se registraron en todas las zonas estudiadas. La mayor abundancia total promedio de especies se registró en verano y la menor en invierno. Se observó un aumento gradual de la abundancia promedio de aves, siendo estos aumentos notables entre primavera y verano de un año a otro. Además, se observó una disminución de la riqueza global de los láridos durante el periodo evaluado. Se observó un patrón de variación estacional del índice de diversidad de Shannon-Weaver (H') similar de un año a otro, debido a que los láridos son aves migratorias, y una tendencia a la disminución del índice con el paso del tiempo. Conclusiones: El HCPA desempeña un papel fundamental para la avifauna acuática de la región. Se ha registrado la presencia de cinco especies migratorias y siete residentes de esta familia, las cuales muestran preferencias espaciales en diferentes zonas del humedal. A pesar de que se observa una disminución en la riqueza global de las especies en el tiempo, la abundancia promedio de aves aumenta.

Abstract Introduction: The coastal wetland Poza de La Arenilla (HCPA), located in Callao (Peru), is an important resting and roosting habitat for aquatic birds, including the family Laridae. However, the wetland is suffering critical degradation due to the development of anthropogenic activities. Objective: To evaluate the spatiotemporal distribution of aquatic birds of the family Laridae reported at HCPA seasonally during the period 2013-2018. Methods: Biweekly sampling was carried out in 11 delimited zones in HCPA between January 2013 and December 2018, during morning and afternoon hours using the total count method. Results: A total of 12 species of Laridae birds were recorded. Leucophaeus pipixcan is the most dominant species in most of the studied zones and its presence is highlighted in summer and spring. The species with the greatest distribution in the wetland was L. pipixcan, Larus dominicanus, and Larus belcheri, which were reported in all the zones studied. The highest average total abundance of species was recorded in summer, while the lowest in winter. A gradual increase in the average abundance of aquatic birds was observed, with these increases being noticeable between the springs and summers from one year to the following. Also, overall richness of the larids was observed to decrease throughout the period evaluated. A similar seasonal variation pattern of the Shannon diversity index (H') was observed from one year to the following, due the fact that Laridae are migratory, and a tendency for the index to decrease with the passage of time. Conclusions: The HCPA plays a key role for the aquatic birds of the region. The presence of five migratory and seven resident species of Laridae has been recorded, which show spatial preferences in different areas of the wetland. Despite a decrease in overall species richness over time, the average abundance of Laridae birds is increasing.

Use of probiotics in the catfish Sorubim cuspicaudus larviculture

Sorubim cuspicaudus, a migratory catfish distributed in the Magdalena, Sinú, and Catatumbo river basins, is categorized as vulnerable to extinction. Production of fingerlings in controlled environments stands as a strategic conservation approach, and larviculture is a critical phase in rearing this species. Probiotics are used for improvement in the critical stages of fingerling production. The study aimed to evaluate the use of probiotics (Bacillus subtilis and Bacillus licheniformis) during the larviculture phase of S. cuspicaudus. Larvae at 42 hours post-hatching (1.5±0.1mg, total length 5.7±0.4mm) were treated with four levels of probiotic inclusion in the water: 0, 5, 10, and 20ppm for 22 days. Water quality remained within suitable ranges for neotropical catfish species larviculture and the parameters assessed were weight gain (Gw), length gain (Gl), specific growth rate (G), survival rate (S), stress resistance (Sr), intestinal fold length (LF), and colony-forming units (CFU) count. Results showed higher Gl (22.23±3.5mm), Gw (40.0±12.6mg), G (14.9±1.5%/day), LP (205±72.7µm), and CFU (118.7±80.9) were found at 20 ppm (p0.05). The findings of this study suggest that probiotics (Bacillus subtilis and Bacillus licheniformis) could be used as an alternative to advance in the S. cuspicaudus larviculture.

Sorubim cuspicaudus, un bagre migratorio distribuido en las cuencas de los ríos Magdalena, Sinú y Catatumbo, se encuentra catalogado como una especie vulnerable a la extinción. La producción de alevinos en ambientes controlados es considerada como una estrategia crucial para su conservación, y la larvicultura es una fase crítica en la cría de esta especie. Para mejorar esta fase crítica de producción de alevinos se utilizan probióticos. El estudio tenía como objetivo evaluar el uso de probióticos (Bacillus subtilis y Bacillus licheniformis) durante la fase de larvicultura de S. cuspicaudus. Las larvas, a las 42 horas post eclosión (1,5±0,1mg, longitud total 5,7±0,4mm) fueron tratadas con cuatro niveles de inclusión de probióticos en el agua: 0, 5, 10 y 20ppm durante 22 días. La calidad del agua se mantuvo dentro de los rangos adecuados para la larvicultura de especies neotropicales de bagre y los parámetros evaluados fueron el aumento de peso (Gw), el aumento de longitud (GL), la tasa específica de crecimiento (G), la tasa de supervivencia (S), la resistencia al estrés (Sr), la longitud del pliegue intestinal (LF) y el recuento de unidades formadoras de colonias (UFC). Los resultados mostraron mayores GL (22,23±3,5 mm), Gw (40,0±12,6 mg), G (14,9±1,5%/día), LP (205±72,7 µm) y UFC (118,7±80,9) a 20 ppm (p0,05). Los resultados de este estudio sugieren que los probióticos (Bacillus subtilis y Bacillus licheniformis) podrían utilizarse como alternativa para avanzar en la larvicultura de S. cuspicaudus.

Semiología de la Migración

Introducción: El fenómeno de la migración genera una serie de experiencias en el ser humano que se traducen en emociones, sentimientos, procesos de adaptación, duelos y procesos psicopatológicos, hasta expresiones patológicas representadas por cuadros clínicos de diferente índole. Objetivo: La intención de este artículo es realizar una reflexión conceptual y clínica de la semiología en torno al concepto y la experiencia de la migración, para con ello ilustrar la complejidad que entraría como fenómeno humano. Método: Revisión narrativa reducida, circunscrita y restringida a los aspectos semiológicos, psicopatológicos y clínicos de la migración. Discusión: La separación, las rupturas y las pérdidas que se derivan de la migración no pasan inadvertidas al individuo, se inscriben en su corporalidad como lesiones fisiológicas que afectan a su vida y como lesiones simbólicas que afectan a su existencia. Conclusiones: La migración supone una ruptura de la totalidad del ser. El contexto, el otro y las relaciones quedan cercenados de la unidad total que es el individuo, como si perdiera la mitad de sí mismo.

Introduction: The phenomenon of migration generates a series of experiences in the human being that are translated into emotions, feelings, adaptation processes, grief and psycho-pathological processes, and even pathological expressions, represented by clinical pictures of different kinds. Objective: The purpose of this article is to carry out a conceptual and clinical reflection on the semiology around the concept and experience of migration, in order to illustrate the complexity that it entails as a human phenomenon. Methods: A reduced narrative review, circumscribed and restricted to the semiological, psychopathological and clinical aspects of migration. Discussion: The separation, ruptures and losses that derive from migration do not go unnoticed by the individual. They are inscribed in his/her corporality as physiological injuries that affect his/her life and as symbolic injuries that affect his/her existence. Conclusions: Migration supposes a rupture of the totality of being. The context, the perception of others and relationships are cut off from the total unity that is the individual, as if he/she lost half of him/herself.

Necrolytic Migratory Erythema—A Case Report of Pancreatic Occupying Lesion / 罕见病研究

Glucagonoma is a rare neuroendocrine tumor of α cells of the pancreas. The tumor excessively secretes glucagon and causes glucagonoma syndrome.70%-90% of patients with glucagonoma will develop necrolytic migratory erythema (NME). We reported a patient of glucagonoma syndrome who was presented to the dermatology outpatient clinic with a 2-year-history of recurrent erythema and scaling on the skin migrating throughout the body. A skin biopsy was performed and resulting features matched with NME, whilst imaging examinations suggested a soft tissue density tumor present in the tail of the pancreas with somatostatin receptor expression and laboratory tests found an elevated levels of serum glucagon. After the diagnosis was confirmed, the patient was treated with surgical resection of the glucagonoma and the skin eruptions resolved rapidly in 4 days. Meanwhile, we reviewed relevant literature published in recent years and summarized its clinical characteristics in order to improve its understanding by clinicians, including clinical manifestations, laboratory and imaging examinations, diagnosis and treatments.

Pancreatic glucagonoma with metastasis followed up for 15 years: A case report / 中华内分泌代谢杂志

To explore the clinical characteristics, diagnosis, and management of pancreatic glucagonoma, a retrospective analysis of the clinical data and diagnostic algorithm of a patient with pancreatic glucagonoma was conducted, along with literature review. Pancreatic glucagonoma is a rare neuroendocrine tumor that originates from the pancreatic alpha cells. The main manifestations of glucagonoma syndrome(GS) include necrolytic migratory erythema, diabetes, anemia, and other systemic involvement. Early diagnosis of GS is challenging and crucial. Early identification and recognition of skin lesions contribute to timely diagnosis and treatment of the disease. Surgical resection is an effective treatment modality for glucagonoma.

AVIAN DIVERSITY (LOCAL AND MIGRATORY BIRDS) AND HABITAT USE OF NANDUR MADHYAMESHWAR BIRD SANCTUARY, NASHIK DISRICT, MAHARASHTRA (INDIA)

This study is mainly based on observation of bird community in Nandur Madhyameshwar area. Nandur Madhyameshwar has a very good biodiversity as well as a wide variety of plants and animals. It is surrounded by large humid terrain and a variety of ?owers and fruit trees, providing food, breeding and nesting support for avian animals. Birds have stable wings, beak, feathers and body temperature. The feathers below keep the birds warm. Contour wings help birds to ?y and attract mates. Birds need a high energy diet to get energy for ?ight. Light bodies and strong muscles help birds to ?y. The pushes the wings to hold the bird in the air. The birds hatch their eggs and keep them in nests. When the chicks come out, they are prehospital or altruistic. A total of 24 different bird species are observed including 14 residents migratory, 2 migratory and 8 residents. It turns out that the respective communities show signi?cant diversity.

Malacological survey along the intertidal zone of Las Piñas-Paranaque Critical Habitat and Ecotourism Area

Background@#One of the eight Ramsar sites in the Philippines is the Las Piňas – Parañaque Critical Habitat and Ecotourism Area(LPPCHEA), and it plays a significant role in the East Asian-Australian Flyway as a stopover site. The migratory birds coming from the north of Asia and Alaska feed on the molluscs in this area. However, there is paucity of literature on the species composition of molluscs found in this critical habitat. Baseline information on these organisms is essential as they are subject to the effects of anthropogenic activities close to and in the wetland, which in turn can have an impact on the ecosystem, particularly the birds foraging in this location. @*Methodology@#The Natural Geography of in-Shore areas (NaGISA) protocol was used for the study. Transects were laid in three sampling sites in Freedom Island and Long Island. The sampling sites were GPS-referenced. A cylinder corer was used to collect mudflat soil, with the corer pushed into the sediment. Soil samples were sieved using a 0.5mm stainless mesh sieve pan, leaving shells and larger sand grains. The molluscs were sorted and identified through taxonomic keys. Sampling was done once for each site in November 2012. @*Results and Discussion@#A total of 61 molluscan species belonging to two classes, 14 orders, and 33 molluscan families were identified and recorded. There were 34 species under the Class Gastropoda that belong to 5 orders and 18 families. For Class Bivalvia, there were 27 species belonging to 8 orders and 15 families. Among the molluscs recorded, 10 species were identified as non-indigenous. It is important to monitor molluscan species as anthropogenic activities may affect these organisms, and in turn, affect the wetland's function for migratory birds. The presence of non-indigenous species may be a potential threat to the ecosystem.@*Conclusion@#Baseline information of the molluscan community in the LPPCHEA was provided by the study. These species provide diet to the endemic and migratory birds in the area. There is a need to monitor these molluscs due to the effects of the man-caused activities close to the area. Also, the non-indigenous species should be studied for their potential to be invasive.

Diagnosed with autism by a dedicated platform, Katal was 4 years old when he was first seen in an health service. In view of his great psychomotor agitation and the difficulty for his parents to weave a narrative while containing him, we decide collectively that this child and his family will be received, as much as necessary, by a duo of professionals: a psychometrician and a psychologist, so as to be able to work in the same time and space on the psychocorporal, psychosocial and intersubjective dynamics at work in this worrying situation. We will show how this device, by introducing therapeutic mediations while accepting to question their relevance, favoured the figuration and the narration of the migratory trajectory of extreme complexity for this family, thus opening the possibility of a dialogue between child and adults, but also between adults, including an inner dialogue of resumption and transformation of traumatic moments linked to the exile

Diagnostiqué autiste par une plateforme dédiée, Katal a 4 ans lorsqu'il est reçu pour la première fois en centre de soin ambulatoire. Devant sa grande agitation psychomotrice et la difficulté pour ses parents de tisser un récit tout en étant contenant pour lui, nous décidons collectivement que cet enfant et sa famille seront reçues, autant que nécessaire, par un duo de professionnel: un psychomotricien et une psychologue, de sorte à pouvoir travailler dans un même temps et un même espace les dynamiques psychocorporelles, psychosociales et intersubjectives à l'œuvre dans cette situation préoccupante. Nous montrerons comment ce dispositif en introduisant des médiations thérapeutiques tout en acceptant d'en questionner la pertinence, a favorisé la figuration et la mise en récit de la trajectoire migratoire d'une extrême complexité pour cette famille, ouvrant ainsi la possibilité d'un dialogue entre enfant et adultes, mais aussi entre adultes, y compris un dialogue intérieur de reprise et de transformation de moments traumatiques liés à l'exil

Alergias alimentarias en pacientes con glositis migratoria benigna / Food allergies in patients with benign migratory glossitis

Introducción: la glositis migratoria benigna, también conocida como lengua geográfica, es una variante normal, que presenta zonas superficiales circulares. Según la literatura revisada, dentro de sus causas figuran los procesos alérgicos, en los que están las alergias alimentarias. Se decidió realizar esta investigación para determinar la prevalencia de las alergias alimentarias frecuentes en estos pacientes mediante pruebas cutáneas. Materiales y métodos: se realizó un estudio descriptivo, longitudinal y prospectivo. La muestra estuvo compuesta por 27 pacientes en el período de enero hasta agosto de 2018 en portadores de glositis migratoria benigna, a los cuales se les realizaron pruebas alérgicas de tipo cutáneas para la determinación de alergias alimentarias. Resultados: el 59,3 % fue mujer y el antecedente alérgico más frecuente fue la rinitis alérgica. El antecedente de alergia alimentaria más frecuente fue los lácteos. Respecto a los resultados de las pruebas para la leche y los mariscos, estas dieron positivas en la mayoría de los pacientes, seguidos por el pescado, los huevos y los frutos secos. La prevalencia de positividad para por lo menos una prueba fue de 85,2%. Discusión: actualmente no existe suficiente literatura que hable sobre las posibles etiologías de la glositis migratoria benigna. Dentro de los antecedentes alérgicos, la rinitis alérgica fue la más frecuente, seguida de la alergia alimentaria. Hasta ahora existen pocas investigaciones que estudien esta prevalencia de alergias alimentarias en los pacientes de forma específica. Conclusión: la lengua geográfica no tiene factor epidemiológico predominante. El antecedente alérgico puede ser un factor predisponente, la alergia alimentaria puede ser desencadenante de la presentación de la lengua geográfica.

Introduction: The benign migratory glossitis, also known as geographic tongue, is a normal variant, which presents circular or irregular depapillated superficial areas. According to the literature reviewed, its causes include allergic processes, among these are food allergies. It was decided to carry out this investigation to determine the prevalence of frequent food allergies in these patients using skin tests. Materials and methods: A descriptive, longitudinal, prospective study was carried out. The sample consisted of 27 patients in the period January-August 2018, carriers of geographic tongue who underwent skin-type allergic tests to determine food allergies. Results: 59.3% were women without statistically significant predominance, the most frequent allergic history was allergic rhinitis. The most frequent history of food allergy was to dairy. Regarding the results of the tests for milk and shellfish, they were positive in 55.6%, followed by fish 14.8%, eggs and nuts with 11.1% respectively. The prevalence of positivity for at least one test was 85.2% with a statistically significant predominance over the negative result. Discussion: There is currently not enough literature that discusses the possible etiologies of benign migratory glossitis. Within the allergic history, allergic rhinitis was the most frequent, followed by food allergy. Until now there are few investigations that study this prevalence of food allergies in patients in a specific way. Conclusion: Geographic tongue does not have a predominant epidemiological factor, an allergic history can be a predisposing factor, food allergy can be a trigger for presentation of geographic language.

Identification and phylogenetic analysis of five highly pathogenic avian influenza (H5N8) viruses isolated in Urumqi in 2016 / 中华微生物学和免疫学杂志

Objective:To analyze the genetic evolution and molecular characteristics of H5N8 avian influenza viruses (AIVs) isolated from the poultry in a live poultry market (LPM) in Urumqi, Xinjiang.Methods:Oropharyngeal and cloacal swabs of poultry were collected from a LPM in Urumqi in 2016. AIVs were isolated by inoculating swab samples into chicken embryos. Hemagglutination test and RT-PCR were used to identify the AIVs. The genes of isolated AIVs were amplified with the universal primers of AIV and whole-genome sequencing was also performed. Pairwise sequence alignment and analysis of phylogenetic and molecular characteristics were performed using BLAST, Clustal W, MEGA-X and DNAStar software.Results:Five H5N8 AIVs were isolated from poultry. These strains shared a nucleotide identity of 99.70%-100.00%, which indicated that they were from the same source, and were named XJ-H5N8/2016. Phylogenetic analysis based on hemagglutinin( HA), NS and PB2 genes showed that these isolates were clustered together with H5N8 AIVs isolated from the migratory swans in Hubei, Shanxi and Sanmenxia, and the ducks in India during 2016 to 2017. Moreover, they were also clustered together with H5N6 AIVs isolated from minks in China and the first case of human infection in Fujian. The phylogenetic tree of neuraminidase( NA) gene indicated the five isolates clustered together with H5N8 AIVs isolated from ducks in India in 2016, and the phylogenetic trees of PB1, MP, PA and NP genes showed that they were clustered together with H5N8 AIVs isolated from wild birds and poultry in Egypt, Cameroon, Uganda, Congo and other African countries in 2017. The HA cleavage sites of XJ-H5N8/2016 contained five consecutive basic amino acids, indicating high pathogenicity. Multiple mutations in the genes of XJ-H5N8/2016 could enhance its virulence and pathogenicity to mammals. Conclusions:The five strains of H5N8 AIVs isolated from the LPM were highly pathogenic and closely related to the H5N8 AIVs isolated from migratory birds and poultry in Hubei, Shanxi, Sanmenxia area, Africa and India during 2016 to 2017. Meanwhile, some of the viral genes were also closely related to the H5N6 AIVs isolated from the minks and human in China. Multiple mutations could increase the virulence and pathogenicity of AIVs to mammals, which could pose a potential threat to public health.

Abundancia de aves playeras (Charadriiformes: Scolopacidae) y su relación con la temperatura del agua en un humedal de Perú (2013-2019) / Abundance of shorebirds (Charadriiformes: Scolopacidae) and its relationship with water temperature in a wetland in Peru (2013-2019)

Resumen Introducción: La familia Scolopacidae (Orden: Charadriiformes) es una de las familias más abundantes en los humedales costeros. El Humedal Costero Poza de la Arenilla cuenta con un registro histórico de 20 especies de escolopácidos; los eventos climáticos podrían afectar la distribución y migración de varias especies de esta familia taxonómica, reduciendo su riqueza y abundancia. Objetivo: Determinar la relación entre la riqueza y la abundancia de las especies pertenecientes a la familia Scolopacidae y la temperatura superficial del mar (TSM) y el índice costero El Niño (ICEN) en el Humedal Costero Poza de la Arenilla. Métodos: Se realizaron muestreos dos veces por mes entre enero 2013 y enero 2019 utilizando el método del conteo total para determinar la abundancia de las especies (N = 292). Se realizó un análisis de correlación de Spearman entre la abundancia, riqueza, TSM e ICEN, y se procedió a calcular la diversidad beta a través del índice de Whittaker, tanto para analizar el recambio anual para cada estación como el recambio estacional dentro de cada año. Resultados: Se obtuvieron dos correlaciones significativas: entre TSM y abundancia y entre ICEN y riqueza. Por otro lado, la prueba ANOSIM arrojó diferencias estacionales en las abundancias de las especies, y la prueba SIMPER arrojó que la mayor diferencia en las abundancias entre estaciones fue entre otoño y primavera (disimilitud de Bray-Curtis = 81.57 %), y la mínima entre invierno y primavera (disimilitud de Bray-Curtis = 49.86 %). Conclusiones: Las dinámicas ecológicas de las comunidades de escolopácidos en La Arenilla se ven modificadas de manera importante en función a las variaciones de los parámetros térmicos ambientales relacionados al cambio climático.

Abstract Introduction: Scolopacidae family (Order: Charadriiformes) is one of the most abundant families found in coastal wetlands. La Arenilla coastal wetland has a historical record of 20 scolopacid species; climatic events could affect the distribution and migration of the several species of this taxonomic family, reducing their species richness and abundance. Objective: The aim of the present study was to determine the relationship between richness and abundance of the species belonging to the Scolopacidae family and both Sea Surface Temperature (SST) and the coastal El Niño index (ICEN) in La Arenilla Coastal Wetland, La Punta, Callao. Methods: Sampling were carried out twice a month, between January 2013 and January 2019 using the Total Count Method in order to determine species abundance (N = 292). A Spearman correlation analysis between abundance, species richness, SST and ICEN was performed, and beta diversity was calculated through the Whittaker index (βw) to analyze both the annual turnover for each season and the seasonal turnover within each year. Results: Two significant correlations were obtained: between SST and abundance and between ICEN and species richness. On the other hand, the ANOSIM test showed seasonal differences in abundance, and the SIMPER test showed that the greatest difference in abundance between seasons was between autumn and spring (Bray-Curtis dissimilarity = 81.57 %), and the minimum difference between winter and spring (Bray-Curtis dissimilarity = 49.86 %). Conclusions: The ecological dynamics of scolopacid communities in La Arenilla coastal wetland face important changes according to the variations in the environmental thermal parameters related to climate change.

Impactos da (des)territorialização nos processos de subjetivação: experiências migratórias de refugiadas venezuelanas em Bogotá / Impacts of (de)territorialization on processes of subjectivation: migratory experiences of Venezuelan refugee women in Bogotá / Impactos de la (des)territorialización en los procesos de subjetivación: experiencias migratorias de refugiadas venezolanas en Bogotá

O presente artigo visa analisar os impactos nos processos de subjetivação de mulheres venezuelanas que, em meio ao forte fluxo migratório recente, se veem diante de um processo de (des)territorialização. Propõem-se discussões sobre elementos do sofrimento ético-político, a construção identitária e a feminização da migração, a partir da produção de narrativas, tendo a categoria de gênero como analisador fundamental de tais fluxos. As entrevistas com mulheres que se encontravam em Bogotá, Colômbia, versaram sobre as memórias da Venezuela, a motivação para a saída, o trânsito na fronteira, a chegada à cidade, as dificuldades cotidianas de adaptação, e os ecos desse processo. Ao final, a escuta dessas experiências emerge como forma de enfrentamento ao silenciamento de vozes marginalizadas e de reflexão sobre as estratégias de acolhimento que têm sido adotadas na região.

This article aims to analyze the impacts on the processes of subjectivation of Venezuelan women who, amidst the strong recent migratory flow, find themselves facing a process of (de)territorialization. Discussions are proposed about elements of ethical-political suffering, identity construction and the feminization of migration, based on the production of narratives, with the gender category as a fundamental analyzer of such flows. The interviews with women who were in Bogotá, Colombia, were about the memories of Venezuela, the motivation to leave, the border traffic, the arrival in the city, the daily difficulties of adaptation, and the echoes of this process. In the end, listening to these experiences emerges as a way of confronting the silencing of marginalized voices and reflecting on the reception strategies that have been adopted in the region.

Potential distribution in Colombia of the introduced fish Pangasianodon hypophthalmus (Siluriformes: Pangasiidae) and implications for endangered native fish / Distribución potencial en Colombia del pez introducido Pangasianodon hypophthalmus (Siluriformes: Pangasiidae) e implicaciones para los peces nativos en peligro de extinción

Abstract Introduction: One of the significant threats to aquatic ecosystems is introducing non-native species in natural environments. This represents one of the principal causes of biodiversity loss in the world. Pangasianodon hypophthalmus is an introduced species in Colombia that shares life characteristics and habitat with endangered native species, such as Ageneiosus pardalis, Sorubim cuspicaudus, and Pseudoplatystoma magdaleniatum. However, its distribution is little-known, and scientists have barely explored the effects on the native fauna. Objectives: To evaluate the P. hypophthalmus invasive potential in some of the Colombian basins, which drain into the Caribbean Sea. Methods: Using records available in various databases, we performed a niche conservatism analysis between the native and introduced records of P. hypophthalmus using the R package Ecospat. Subsequently, we modeled the potential invasion area of P. hypophthalmus and the distribution areas of three native species, performing ecological niche modeling (ENM) using the Maxent algorithm. Finally, we calculated a geographic niche overlap between the non-native and native species. Results: The Ecospat spatial analysis indicated that P. hypophthalmus retains some environmental niche attributes through space. For this reason, we can use ENM as an approximation to its range of distribution in the invaded area. Our results using ENM demonstrated that the four species analyzed prefer low and slightly rocky regions; therefore, the geographical overlap of the three native species' ecological niches and the introduced species exceed 80 %. Conclusions: There are adequate conditions in the study basins to fully establish the species P. hypophthalmus, representing a high risk for aquatic ecosystems and native ichthyofauna. Knowledge of the potential distribution areas is essential to implement control of the species.

Resumen Introducción: Una de las amenazas importantes para los ecosistemas acuáticos es la introducción de las especies no nativas en ambientes naturales. Esto representa una de las principales causas de pérdida de biodiversidad en el mundo. Pangasianodon hypophthalmus es una especie introducida en Colombia que comparte características de vida y hábitat con especies nativas en peligro de extinción como: Ageneiosus pardalis, Sorubim cuspicaudus y Pseudoplatystoma magdaleniatum. Sin embargo, poco se conoce de su distribución y los efectos en la fauna nativa han sido poco explorados. Objetivo: Evaluar el potencial invasivo de P. hypophthalmus en algunas de las cuencas colombianas que desembocan en el Mar Caribe. Métodos: Utilizando registros disponibles en varias bases de datos, realizamos un análisis de conservadurismo de nicho entre los registros nativos e introducidos de P. hypophthalmus usando el paquete de R Ecospat. Posteriormente, modelamos el área potencial de invasión de P. hypophthalmus y las áreas de distribución de tres especies nativas realizando modelos de nicho ecológico (MNE) utilizando el algoritmo de Maxent. Finalmente, calculamos una superposición de nicho geográfico entre las especies nativas y no nativas. Resultados: El análisis espacial de Ecospat indica que P. hypophthalmus conserva algunos atributos del nicho ambiental a través del espacio. Por esta razón, podemos usar los MNE como una aproximación a su rango de distribución en el área invadida. Nuestros resultados usando MNE demostraron que las cuatro especies analizadas prefieren regiones bajas y ligeramente rocosas; por ello, la superposición geográfica de los nichos ecológicos de las tres especies nativas y la especie introducidas superan el 80 %. Conclusiones: Existen condiciones adecuadas en las cuencas de estudio para el establecimiento completo de la especie P. hypophthalmus, lo que representa un alto riesgo para los ecosistemas acuáticos y la ictiofauna nativa. El conocimiento de las áreas de distribución potencial es fundamental para implementar controles sobre la especie.

Migratory Glossitis Associated with Cleft Tongue: Case Report / Glossite Migratória Associada a Língua Fissurada: Relato de Caso

Benign migratory glossitis, also known as geographic tongue, is characterized by the tongue inflammation and is associated with pain and difficulty eating due to the lingual papillae atrophy. It may appear in association with the fissured tongue. This paper reports the case of a 47-year-old male patient who sought dental care with the main complaint of burning, discomfort, increased sensitivity and a burning sensation on the tongue. He was diagnosed with migratory glossitis associated with a fissured tongue. The patient treatment was performed with an ointment based on triamcinolone acetonide (Omcilon- A Orabase®), which showed improvement in the clinical signs after seven days. The therapy used in this patient was effective in restoring the tongue papillae and improving signs and symptoms.

A glossite migratória benigna, também conhecida como língua geográfica, caracteriza-se por inflamação da língua e está associada a dor e dificuldade na alimentação devido a atrofia das papilas linguais. Pode aparecer em associação à língua fissurada. Este trabalho relata o caso de um paciente do sexo masculino com idade de 47 anos que buscou atendimento odontológico com queixa principal de ardência, desconforto, sensibilidade aumentada e sensação de queimação na língua. Foi diagnosticado com glossite migratória associada a língua fissurada. O tratamento do paciente foi realizado com pomada à base de triancinolona acetonida (Omcilon- A Orabase®) demonstrou melhora no quadro clinico após sete dias. A terapêutica usada neste paciente foi eficaz no restabelecimento das papilas da língua e melhora dos sinais e sintomas.

Behavioral aspects of waterbirds / Aspectos comportamentais de aves aquáticas

Abstract Estuaries are used by waterbirds as foraging, resting and nesting sites, serving also as shelter for migratory birds. The dynamics of this avifauna in an aquatic environment may be associated with the differences of time of day, tide height, temperature, wind speed and use of the site by different species. This study had the objective of evaluating behavioral aspects of aquatic birds, relating the influence of environmental variables with their activities. Bird counts were performed at the mouth of two important rivers of the state of Santa Catarina, Brazil, during two-hour intervals throughout the day in monthly samplings between June (2015) and May (2016). A total of 44 species were recorded, ten of which were migratory. The most recorded behaviors were foraging and resting. The Kruskal-Wallis analysis indicated no significant difference in behavior between the sampling intervals. The Bray-Curtis similarity test resulted in three groups: 1) - species that foraged most of the time; 2) - species that rested most of the time; and 3) - same time in both activities. The Indicator Species Analysis showed that 17 species were associated with only one microhabitat and 15 species with more than one. The Canonical Correlation Analysis indicated that only tide height, temperature and rainfall variables were correlated with the behaviors performed and only the resting activity was positively correlated with all variables. This may be associated with thermoregulation and the ability of some species to stay in midlitoral at high tide. The results demonstrate that different waterbird species used the studied areas in different ways. Thus, the heterogeneity of microhabitats in an aquatic environment of extreme importance for the coexistence and maintenance of the diversity of waterbirds.

Resumo Estuários são utilizados por aves aquáticas como locais de forrageio, descanso e nidificação, servindo, também, como pontos de parada para aves migratórias. A dinâmica dessa avifauna em um ambiente pode estar associada a diferenças entre horários do dia, altura da maré, temperatura, velocidade do vento e uso do local. Esse trabalho teve o objetivo de avaliar aspectos comportamentais de aves aquáticas, relacionando a influência de variáveis ambientais com suas atividades. Amostragens mensais foram realizadas na foz de dois importantes rios do Estado de Santa Catarina, Brasil, entre junho de 2015 e maio de 2016, em intervalos de duas horas no decorrer do dia. Um total de 44 espécies foram registradas, dez das quais foram migratórias. Os comportamentos mais observados foram forrageio e descanso. A análise de Kruskall-Wallis não indicou diferenças significativas no comportamento entre os horários de amostragem. O teste de similaridade Bray-Curtis resultou em três agrupamentos: 1) - espécies que forragearam na maior parte do tempo; 2) - espécies que descansaram na maior parte do tempo; e 3) - mesma quantidade de tempo em ambas atividades. A Análise de Espécies Indicadoras mostrou que 17 espécies estiveram associadas com apenas um microhabitat e 15 espécies com mais de um. A Análise de Correlação Canônica indicou que apenas as variáveis maré, temperatura e precipitação foram significativamente correlacionadas com os comportamentos demonstrados e apenas a atividade de descanso foi positivamente correlacionada com as todas as variáveis. Isso pode estar associado com a termorregulação e com a habilidade de algumas espécies de permanecer no mediolitoral durante a maré cheia. Os resultados demonstram que diferentes espécies de aves aquáticas utilizaram as áreas estudadas de diferentes maneiras. Assim, a heterogeneidade de microhabitats em um ambiente aquático é de extrema importância para a coexistência e a manutenção da diversidade de aves.

Impacts on fisheries assessed by local ecological knowledge in a reservoir cascade in the lower São Francisco River, northeastern Brazil

Our study assessed the fishers' perception (local ecological knowledge, LEK) concerning environmental impacts on fisheries and fish species in the final portion of Sub-Middle and Lower São Francisco. The river was divided into four areas where 107 fishers from 22 locations (4 states) were surveyed. The dam was the most significant impact on fisheries. The loss of connectivity, changing the environmental complexity, and its secondary effects (e.g., flow control, interruption of migratory routes) were determining factors. Other impacts were pointed out, such as pollution, macrophytes, overfishing, non-native species, and aquaculture. Among migratory species, Pseudoplatystoma corruscans and Salminus franciscanus have been absent from fishery catches for decades. Prochilodus argenteus records in fisheries are likely associated with migration routes to small tributaries. The environmental disturbance favored the establishment of non-native species such as Oreochromis niloticus, Cichla monoculus, and Metynnis lippincottianus along the studied section. Over the final portion of the São Francisco River, the more significant seawater intrusion changed the target species for fisheries activities. Thus, our data validate the importance of fishers' LEK and reinforce the adverse effects of the reservoir cascade on fishing and migratory fishes.(AU)

Nosso estudo avaliou a percepção dos pescadores (conhecimento ecológico local, CEL) em relação aos impactos ambientais sobre a pesca e peixes no trecho final do Submédio e Baixo São Francisco. O rio foi dividido em quatro áreas onde foram entrevistados 107 pescadores de 22 localidades (4 estados). Barragem foi o impacto mais significativo sobre a pesca. A perda da conectividade alterando a complexidade ambiental e seus efeitos secundários (e.g., controle da vazão, interrupção da rota migratória) foram fatores determinantes. Outros impactos foram apontados, como poluição, macrófitas, sobrepesca, espécies introduzidas e piscicultura. Dentre as espécies migradoras, Pseudoplatystoma corruscans e Salminus franciscanus estão ausentes da pesca há décadas. Os registros de Prochilodus argenteus nas pescarias provavelmente estão associados às rotas migratórias para pequenos tributários. A perturbação ambiental favoreceu o estabelecimento de espécies introduzidas como Oreochromis niloticus, Cichla monoculus e Metynnis lippincottianus ao longo do trecho estudado. No trecho final do rio São Francisco, a maior intrusão de água do mar mudou as espécies-alvo da pesca. Dessa forma, nossos dados validam a importância do conhecimento ecológico local dos pescadores e reforçam os efeitos adversos das cascatas de reservatórios sobre a pesca e peixes migratórios.(AU)

Metapopulation dynamics of the migratory fish Prochilodus lineatus (Characiformes: Prochilodontidae) in a lotic remnant of the Grande River, Southeastern Brazil

River impoundments for electricity generation lead to environmental changes which severely affect fish migration and species richness. However, little is known about their effect on the genetic structure and population dynamics downstream from the reservoir. Here, we analyzed a set of ten microsatellite loci of Prochilodus lineatus, an important South American migratory fish. Specimens (n = 150) were sampled from five sites in a remnant lotic system that includes sections of the Grande, Pardo and Mogi Guaçu rivers, southeastern Brazil. The data showed that all microsatellites were polymorphic with the allele number per locus ranging from 5 to 32, and genetic diversity (H e ) varied from 0.74 to 0.80. Indices of genetic differentiation and Bayesian analysis showed a significant genetic structure and three genetic clusters inhabiting this river system. An asymmetric gene flow suggests source-sink metapopulation dynamics from tributaries (genetic source) to the main river (genetic sink). A genetic cluster that was not detected in the upper Mogi and Pardo rivers tributaries may indicate there is a "trapped gene pool" downstream from the Porto Colômbia dam. Thus, here we provide new insights into the genetic structure and population dynamics of a migratory fish species in a highly dammed river basin.(AU)

Represamento de rios para geração de eletricidade levam a mudanças ambientais que afetam severamente a migração de peixes e riqueza de espécies. No entanto, pouco se sabe sobre seu efeito na estrutura genética e dinâmica populacional a jusante de reservatórios. Aqui, analisamos um conjunto de dez loci de microssatélites de Prochilodus lineatus, um importante peixe migratório sul-americano. Os espécimes (n = 150) foram amostrados em cinco locais de um sistema lótico remanescente que inclui seções dos rios Grande, Pardo e Mogi Guaçu, sudeste do Brasil. Os dados mostraram que todos microssatélites eram polimórficos com o número de alelos por locus variando de 5 a 32 e diversidade genética (H e ) variou de 0,74 a 0,80. Índices de diferenciação genética e análise de agrupamento baseada em modelo bayesiano indicou a presença de três agrupamentos genéticos habitando este sistema fluvial. Um fluxo gênico assimétrico sugere dinâmica metapopulacional de fonte-sumidouro dos tributários (fonte genética) para o rio principal (sumidouro genético). Um agrupamento genético que não foi detectado nos tributários rio Mogi e rio Pardo parecem indicar que há um "trapped gene pool" a jusante da represa de Porto Colômbia. Assim, nós provemos aqui novos conhecimentos sobre a estrutura genética e dinâmica populacional de uma espécie de peixe migratório em um rio altamente fragmentado por barramentos.(AU)

Drifting in a free-flowing river: Distribution of fish eggs and larvae in a small tributary of a Neotropical reservoir / À deriva em um rio de fluxo livre: Distribuição de ovos e larvas de peixes em um pequeno afluente de um reservatório Neotropical

Abstract: We investigated spatial and temporal variations in the distribution of fish eggs and larvae in the Guareí River, a free-flowing tributary located in the upper section of the Jurumirim Reservoir, Paranapanema River, Brazil. Fish eggs and larvae were sampled ~ fortnightly from November 2017 to March 2018 (Cycle 1), and from November 2018 to March 2019 (Cycle 2), at three sites distributed along the entire course of the Guareí River. We collected 859 fish eggs and 1,340 larvae, comprising 19 taxa. We found reproductive activity of several fish species in the Guareí River, including long-distance migrants. However, there was no spatial differences in the assemblage structure and densities of fish eggs and larvae along the channel of Guareí River. We recorded temporal differences in larvae density only in Cycle 2. The consistent capture of fish eggs and larvae in two reproductive cycles is strong evidence that this river is a spawning site for a variety of fish species. Thus, we recommend maintaining its natural flow regime.

Resumo: Investigamos as variações espaciais e temporais na distribuição de ovos e larvas de peixes no rio Guareí, um afluente de fluxo livre localizado na parte superior do Reservatório de Jurumirim, bacia do rio Paranapanema, Brasil. Ovos e larvas de peixes foram amostrados ~ quinzenalmente de novembro de 2017 a março de 2018 (Ciclo 1), e de novembro de 2018 a março de 2019 (Ciclo 2), em três locais distribuídos ao longo de todo o curso do rio Guareí. Foram coletados 859 ovos de peixes e 1.340 larvas, compreendendo 19 táxons. Nós encontramos atividade reprodutiva de várias espécies no rio Guareí, incluindo espécies migradoras de longa distância. Contudo, não houve diferenças espaciais na estrutura das assembleias e nas densidades de ovos e larvas e ao longo do canal do rio Guareí. Diferenças temporais foram significativas apenas para densidade de larvas no Ciclo 2. A captura consistente de ovos e larvas de peixes em dois ciclos reprodutivos é uma forte evidência de que este rio é um local para a reprodução de várias espécies de peixes. Assim, recomendamos a manutenção do seu regime de fluxo natural.

Invertendo o enfoque das "crises migratórias" para as "migrações de crise": uma revisão conceitual no campo das migrações / From "migration crisis" to "crisis migration": a conceptual review within the migration studies field / De "crisis migratoria" a "migraciones de crisis": una revisión conceptual en el campo de estudios de las migraciones

O presente artigo se propõe a debater um novo conceito no campo de estudos migratórios - as migrações de crise -, o qual traz à luz os processos, motivos e fatores vivenciados por populações afetadas por crises e que podem contribuir para processos migratórios de indivíduos, famílias e comunidades como um todo. Introduzindo diversas categorias correlatas - como a eventualidade, a imobilidade (ou enclausuramento) e a não escolha -, adota-se um direcionamento metodológico e conceitual que aponta para as crises como propulsoras das migrações. Dessa maneira, busca-se tensionar a ideia de que as migrações geram crises aos Estados-nação receptores de movimentos significativos de pessoas - a qual notavelmente se consolida pela disseminação do termo "crise migratória", em especial, nos discursos políticos e midiáticos correntes. A delimitação do novo conceito proposto e da sua metodologia de estudo pautou-se pela revisão bibliográfica da literatura especializada na área, com foco em pesquisas recentes sobre as migrações de crise e suas implicações tanto na esfera local como na internacional. Ao final do texto, levantamos os desafios e as contribuições de tal conceito, envolvendo debates centrais no campo das migrações, inobstante questões teórico-metodológicas

This article aims to debate a new concept within the migration studies field which is named "crisis migration", shedding light on the processes, motives and factors that influence the movement of populations affected by crisis. Introducing other interrelated categories - such as eventuality, immobility and non-choice - , the article is guided by a methodological and conceptual perspective that understands crisis as a driver to migration. Therefore it seeks to defy the idea that migrations generate crisis to nation-states receiving large contingents of people. This idea has been consolidated by the term "migration crisis" especially disseminated in the midia and political discourses. Our discussion of the new concept was based on bibliographic review, focusing on recent researchs in respect to crisis migration and its unfoldings not only in the local but also in the international scenario. Finally, we bring about the challenges as well as the contributions of this concept, which involve unsolved central debates within the migration field.

Este artículo tiene como objetivo discutir un nuevo concepto en el campo de los estudios migratorios, las migraciones de crisis, que saca a la luz los procesos, los motivos y los factores experimentados por las poblaciones afectadas por las crisis y que pueden contribuir a los procesos migratorios de las personas, las familias y comunidades en su conjunto. Al introducir varias categorías relacionadas, como eventualidad, inmovilidad (o confinamiento) y no elección, se adopta una dirección metodológica y conceptual que apunta a las crisis como motores de la migración. De esta manera, buscamos tensionar la idea de que la migración genera crisis en los Estados-nación que reciben movimientos significativos de personas, lo que se consolida notablemente por la difusión del término crisis migratoria, especialmente en los discursos políticos y mediáticos actuales. La delimitación del nuevo concepto propuesto y su metodología de estudio fue guiada por la revisión bibliográfica de la literatura especializada en el área, con un enfoque en investigaciones recientes sobre migraciones de crisis y sus implicaciones tanto a nivel local como internacional. Al final del texto, planteamos los desafíos y las contribuciones de dicho concepto, involucrando debates centrales en el campo de las migraciones, a pesar de los problemas teóricos y metodológicos que aún no se han superado suficientemente dentro de este.
