O abutre real (Sarcoramphus papa) é um pássaro compacto de cor extraordinária, cabeça nua, possui carúnculas e papilas carnudas vermelhas e alaranjadas em torno do bico, a íris é branca com um anel orbital vermelho. Em cativeiro, o estresse é uma condição bastante observada, o que pode levar a automutilação, podendo evoluir para lesões graves na pele e músculos. O objetivo do presente relato é descrever os procedimentos adotados em um caso de automutilação em Sarcoramphus papa, mantido em cativeiro, e a importância do manejo adequado para essa espécie em cativeiro. Foi atendido em um Hospital Veterinário Universitário, um urubu-rei apresentando ferimento contaminado, com exposição óssea na asa direita. Após tratamento o animal foi encaminhado para uma reserva conservacionista para que fosse condicionada a voltar para seu habitat natural.(AU)

The real vulture is a compact bird of extraordinary color (in adult plumage). Its bare head, as the scientific name suggests, has caricatures and fleshy red papillae applied around the beak, and an iris of the eye is white with a red orbital ring. In captivity, stress is a widely observed condition, which can lead to self-mutilation, which can progress to severe skin and muscle injuries. The purpose of this report is to describe the procedures adopted in the case of automation in Sarcoramphus papa, kept in captivity and with an importance of the appropriate manual for this species in captivity. He was seen at a University Veterinary Hospital, a king vulture showed a contaminated wound, with bone exposure on the right. After treatment or animal was sent to a conservation reserve to be conditioned and return to its natural habitat.(AU)

The importance of the dog (Canis lupus familiaris) in cocoa farms as carriers of helminths potentially transmissible to humans and wildlife in the Southern Bahia, Brazil / A importância do cão (Canis lupus familiaris) nas fazendas de cacau como portador de helmintos potencialmente transmissíveis ao homem e à vida selvagem no sul da Bahia, Brasil

Domestic dogs (Canis lupus familiaris) can be considered an invasive species as they have been introduced by humans in different parts of the world and represent a risk to wildlife conservation. Large extensions of agroforestry systems, where cocoa is grown under the shade of native trees, contribute to wildlife conservation in southern Bahia, Brazil. However, this system can increase contact between species of the native fauna and domestic dogs, which are frequently taken to the fields by rural workers. The aims of this study were to investigate the presence of domestic dogs inside cocoa agroforestry systems and the occurrence of helminths in dogs from cocoa farms near two protected areas: the Una Biological Reserve (REBIO-Una) and the Serra das Lontras National Park in Una, Bahia. We also investigated general characteristics of the dogs such as age, sex, breed, feeding frequency, vaccination, deworming and others, and evaluated possible risks of wildlife and human contamination by the domestic dog parasites. Camera traps were set up on eight cocoa agroforestry systems and three adjacent forest fragments. For parasitological investigation, fecal samples were collected from domestic dogs that lived on the eight cocoa farms. A total of 539 photos of 12 mammals were registered, of which 15% were of domestic dogs. The parasitological research was carried out with fecal samples from 32 of the 39 dogs that lived in the cocoa farms. We found one genus of cestode, Dipylidium sp. (7.7%), and five genera of nematodes, Ancylostoma sp. (80.7%), Strongyloides sp. (38.4%), Toxocara sp. (30.7%), Spirocerca sp. (15.4%) and Trichuris sp. (11.5%). Regarding animal care, all dogs were in poor body condition, 49% were fed twice a day, 90% defecated in the forest or cocoa agroforestry systems, only 33% were periodically dewormed, 64% were vaccinated against rabies in less than 12 months, and only one dog was vaccinated against other viruses. The results showed that domestic dogs share the same environment as wild animals yet lack some basic health care, increasing the possibility of parasitic transmission between domestic dogs, wildlife and humans from environmental contamination. We highlight the need for responsible pet ownership and the monitoring the health of wild animals and the human population living in this region.

Cães domésticos (Canis lupus familiaris) podem ser considerados espécies invasoras introduzidas pelo ser humano em diversos lugares do mundo, representando risco para a conservação da fauna. Grandes extensões de sistemas agroflorestais, onde o cacau é cultivado sob a sombra de árvores nativas, contribuem para a conservação da vida selvagem no sul da Bahia, Brasil. Entretanto, esse sistema pode aumentar o contato entre espécies da fauna nativa e cães domésticos, frequentemente levados para o campo por trabalhadores rurais. Os objetivos deste estudo foram investigar a presença de cães domésticos em sistemas agroflorestais de cacau e a ocorrência de helmintos em cães de fazendas de cacau nas proximidades de duas áreas protegidas: a Reserva Biológica de Una (REBIO-Una) e o Parque Nacional da Serra das Lontras, em Una, Bahia. Também foram investigadas as características gerais dos cães como idade, sexo, raça, frequência de alimentação, vacinação, vermifugação e outros, e avaliados os possíveis riscos de contaminação da vida selvagem e seres humanos por parasitas de cães domésticos. Armadilhas fotográficas foram instaladas em oito sistemas agroflorestais de cacau e três fragmentos florestais adjacentes. Para investigação parasitológica, foram coletadas amostras fecais de cães domésticos que viviam nas oito fazendas de cacau. Foram registradas 539 fotos de 12 mamíferos, onde 15% das fotos pertenciam à cães domésticos. A pesquisa parasitológica foi realizada com amostras fecais de 32 dos 39 cães que viviam nas fazendas de cacau. Encontramos um gênero de cestóide: Dipylidium sp. (7,7%), e cinco gêneros de nematóides: Ancylostoma sp. (80,7%), Strongyloides sp. (38,4%), Toxocara sp. (30,7%), Spirocerca sp. (15,4%) e Trichuris sp. (11,5%). Em relação aos cuidados com os animais, todos estavam com score corporal baixo, 49% dos cães eram alimentados duas vezes ao dia, 90% defecam na floresta ou em sistemas agroflorestais de cacau, apenas 33% foram vermifugados periodicamente, 64% vacinados contra a raiva em menos de 12 meses e apenas um cão foi vacinado contra outros vírus. Os resultados mostram que os cães domésticos compartilham o mesmo ambiente que os animais silvestres e carecem de alguns cuidados básicos de saúde, aumentando a possibilidade de trânsito parasitário entre cães domésticos, animais silvestres e humanos por contaminação ambiental. Destaca-se a necessidade de atividades de posse responsável de animais de estimação e o monitoramento da saúde dos animais silvestres e da população humana que vive nesta região.

Eficiencia de las unidades de conservación definidas en la Reserva Natural Iberá (Argentina) en la protección de la diversidad de reptiles / Efficiency of conservation units defined in Iberá Natural Reserve (Argentina) in protecting reptile's diversity

Ante la acelerada pérdida de biodiversidad causada por actividades humanas, las áreas protegidas (APs) constituyen la principal respuesta para mitigar esta crisis. La Reserva Natural Iberá (RNI) incluye 13000 km2 de territorios privados y fiscales, que contienen humedales y tierras altas con elevada biodiversidad, endemismos e importantes poblaciones de especies amenazadas. Para implementar su conservación, a finales del siglo pasado se definieron cinco Unidades de Conservación (UC) priorizadas en infraestructura y guardaparques, seleccionadas mediante criterios pobremente explicitados. En este trabajo definimos áreas prioritarias para la conservación (APC) usando los patrones de distribución de los reptiles en la RNI, para evaluar la eficiencia de las UC instauradas y detectar otras posibles áreas a ser consideradas en gestiones de conservación. La RNI se dividió en 28 celdas de 0,25° de latitud-longitud y mediante muestreos de campo y revisión de colecciones se obtuvieron 1 482 registros de 71 especies de reptiles computándose su presencia/ausencia en las celdas. Se calculó por celda riqueza específica e Índice Combinado de Biodiversidad (ICB) (que incluye rareza y grado de amenaza). Las APC fueron definidas mediante una búsqueda exacta (Complementariedad), obteniendo el mínimo conjunto de áreas que contuvieran a todas las especies y valores del ICB, lo que se denomina "eficiencia máxima". La superficie mínima necesaria que representa a todas las especies es de diez celdas (36%) y sólo dos incluyen UC actuales. Se necesitan adicionar ocho celdas para cubrir los vacíos de conservación de reptiles, particularmente en el norte de la RNI. Sobre 20 especies amenazadas o insuficientemente conocidas, 12 (60%) no fueron registradas en celdas con UC. Proponemos UC adicionales para efectivizar la protección de todos los reptiles e incluir especies amenazadas.(AU)

Owing to accelerated biodiversity loss caused by human activities, the protected areas (PAs) are the main response to mitigate this crisis. The Iberá Natural Reserve (INR) includes 13000 km2 of private and state lands, which contain wetland and upland areas with high biodiversity, endemism and significant populations of threatened species. In order to implement its conservation, late last century, five Units of Conservation (UC) were defined and prioritized due to infrastructure and park-rangers, although poorly selected by explicit criteria. We defined priority areas for conservation (APCs) using the distribution patterns of reptiles in the INR, in order to evaluate the efficiency of the five UC located within its boundaries and detect other possible areas to be considered in conservation efforts. The INR was divided into 28 quadrat-cells of 0.25° latitude-longitude and through field samplings and revision of collections we obtained 1482 records of 71 species of reptiles, computed their presence / absence in the cells. We estimated species richness and Combined Biodiversity Index (including rarity and degree of threat) by cell. APCs were defined by an exact search (complementarity index), obtaining the minimum set of areas containing higher values of the indexes used, which is called "maximum efficiency". The minimum area required to represent all species was ten cells (36%) and only two of them includes current UC. Add eight cells are needed to fill conservation gaps of reptiles, particularly in the north of the INR. About 20 threatened or poorly known species, 12 (60%) were not recorded in cells with UC. We proposed additional UC in order to protect all reptiles and include threatened species.(AU)

Tmesiphantes mirim sp. nov. (Araneae: Theraphosidae) from the Atlantic Forest of Bahia, Brazil, biogeographical notes and identification keys for species of the genus

A new species of Tmesiphantes Simon, 1892 is described and illustrated, based on eight male specimens collected at the Una Biological Reserve, southern state of Bahia, Brazil. It is distinguished by the morphology of male palpal bulb and tibial apophysis. The new species is very small and is the smallest theraphosid described to date (body length 5.5 mm). It is distinguished from congeners by the size, which vary from 12 mm (T. riopretano) to 23.8 mm (T. nubilus) in other species of the genus, aspect of palpal bulb, sternal posterior sigillae close to sternal margin and by the aspect of tibial apophysis which lacks the prolateral branch. Tmesiphantes presently comprises nine species. Sixth have been described for the southern region of Bahia, a well known area of endemism in the Atlantic Forest. Identification keys for Tmesiphantes males and females are presented. (AU)

Assessing the performance of macroinvertebrate metrics in the Challhuaco-Ñireco System (Northern Patagonia, Argentina) / Evaluación del rendimiento de distintas métricas utilizando los macroinvertebrados en el sistema lótico de Challhuaco-Ñireco (Patagonia, Argentina)

Siete sitios fueron examinados en el sistema lótico Challhuaco-Ñireco, ubicado dentro del Parque Nacional Nahuel Huapi (PNNH), sin embargo parte de esta cuenca está urbanizada ya que atraviesa la ciudad de San Carlos de Bariloche (150,000 habitantes). Se midieron variables físico-químicas y se colectaron los macroinvertebrados bentónicos durante tres años consecutivos en siete sitios desde la cabecera hasta la desembocadura. Plecoptera, Ephemeroptera, Trichoptera y Diptera predominaron en los sitios cercanos a la cabecera, mientras que Diptera, Oligochaeta y Mollusca dominaron los sitios más bajos cercanos a la desembocadura. En relación con los grupos funcionales, los colectores-recolectores fueron los dominantes en todos los sitios y este patrón fue consistente durante los tres años de muestreo. El análisis de ordenamiento (RDA) reveló que las distribuciones de los ensambles de especies respondieron al gradiente climático y topográfico (temperatura y elevación), pero también fueron asociados con variables relacionadas al impacto antrópico (conductividad, contenido de nitratos y fosfatos). Los ensambles en cabecera estuvieron representados por insectos sensibles, mientras que los taxones tolerantes como Tubificidae, Lumbriculidae, Chironomidae y el crustáceo Aegla sp. fueron dominantes en los sitios urbanizados. En relación con las métricas analizadas, la Riqueza total, el EPT taxa, la diversidad de Shannon y el índice biótico BMPS evidenciaron diferentes niveles de disturbio en el sistema, demostrando que estas medidas son una excelente herramienta para determinar el estado de los ríos de montaña de la Patagonia.(AU)

Seven sites were examined in the Challhuaco-Ñireco system, located in the reserve of the Nahuel Huapi National Park, however part of the catchment is urbanized, being San Carlos de Bariloche (150,000 inhabitants) placed in the lower part of the basin. Physico-chemical variables were measured and benthic macroinvertebrates were collected during three consecutive years at seven sites from the headwater to the river outlet. Sites near the source of the river were characterised by Plecoptera, Ephemeroptera, Trichoptera and Diptera, whereas sites close to the river mouth were dominated by Diptera, Oligochaeta and Mollusca. Regarding functional feeding groups, collector-gatherers were dominant at all sites and this pattern was consistent among years. Ordination Analysis (RDA) revealed that species assemblages distribution responded to the climatic and topographic gradient (temperature and elevation), but also were associated with variables related to human impact (conductivity, nitrate and phosphate contents). Species assemblages at headwaters were mostly represented by sensitive insects, whereas tolerant taxa such as Tubificidae, Lumbriculidae, Chironomidae and crustacean Aegla sp. were dominant at urbanised sites. Regarding macroinvertebrate metrics employed, total richness, EPT taxa, Shannon diversity index and Biotic Monitoring Patagonian Stream index resulted fairly consistent and evidenced different levels of disturbances at the stream, meaning that this measures are suitable for evaluation of the status of Patagonian mountain streams.(AU)

Trypanosomatids in phyllostomids (chiroptera, phyllostomidae) from Perobas Biological Reserve, Paraná, Brazil / Tripanossomatídeos em filostomídeos (chiroptera, phyllostomidae) da Reserva Biológica das Perobas, Paraná, Brasil / Tripanossomatídeos en filostomídeos (chiroptera, phyllostomidae) de la Reserva Biológica de las Perobas, Paraná, Brasil

The family Trypanosomatidae reunites a great number of species which parasite several organisms, among them, chiropterans, which may act as reservoirs. The present study aimed at demonstrating the occurrence of trypanosomatids in the blood of phyllostomids from Perobas Biological Reserve, Paraná, Brazil. The capture of the animals was performed with the aid of mist nets in July and August, 2008. The bats were contained manually and for the parasite analysis, a small drop of blood was collected in order to prepare imprint samples which were fixed in absolute methanol. In the laboratory, the slides were stained by the method of Giemsa, observed and photographed with the aid of a light microscope. Fifteen positive results were found out of 33 animals captured. Five of the species captured, Artibeus lituratus, Artibeus fimbriatus, Artibeus planirostris, Artibeus obscurus and Sturnira lilium presented trypanosomatids. Only two species did not have positive slides, Carollia perspicillata and Pygoderma bilabiatum. The species with positive slides have a diversified diet, including the ingestion of insects, which may facilitate the infection. These results contribute with information about the occurrence of these blood parasites in bats since studies about the subject in Brazil are scarce.(AU)

A família Trypanosomatidae reúne grande número de espécies que parasitam os mais diversos organismos, entre eles, os quirópteros, que podem atuar como reservatórios. O presente estudo teve por objetivo investigar a ocorrência de tripanossomatídeos no sangue de filostomídeos da Reserva das Perobas, Paraná. A captura dos animais ocorreu com o uso de redes de neblina, nos meses de julho e agosto de 2008. Os morcegos foram contidos manualmente, e, para a análise dos parasitas, uma gotícula de sangue foi retirada para a confecção do esfregaço e fixação com metanol absoluto. No laboratório as lâminas foram coradas pelo método Giemsa, observadas e fotografadas ao microscópio. Foram obtidos 15 resultados positivos dos 33 exemplares capturados, sendo que cinco das sete espécies capturadas, Artibeus lituratus, Artibeus fimbriatus, Artibeus planirostris, Artibeus obscurus e Sturnira lilium, apresentaram tripanossomatídeos sanguíneos. Somente em Carollia perspicillata e Pygoderma bilabiatum, não foram constatados esses parasitos. Os animais com resultados positivos têm uma dieta bastante diversificada, incluindo a ingestão de insetos, o que pode acarretar infecções, caso alimentem-se de insetos contaminados. Esses resultados contribuem com as informações acerca da ocorrência de parasitas sanguíneos em morcegos, haja vista a escassez de estudos sobre o assunto no Brasil. (AU)
