Composition and diversity of acaroids mites (Acari: Astigmata) community in the stored rhizomatic traditional Chinese medicinal materials / La composición y la diversidad de ácaros (Acari: Astigmata) en productos de la medicina tradicional china

Objective: To investigate the species and breeding density of ac aroid mites in the stored rhizomatic traditional Chinese medicinal materials in Anhui province, China, in order to supply evidences for control and prevention of such species. Methods: The stored traditional Chinese medicinal materials of root-stock origins were collected in 30 herb stores and warehouses in 17 cities across Anhui province. Mites were collected by using Tullgren funnel and directicopy, and identified under microscopy. Results: Twenty-two species of acaroid mites, belonging to 15 genera under 5 families, were identified from the total 47 stored samples, in which Tyrophagus putrescentiae, Acarus farinae, Carpoglyphus lactis, and Cologlyplus berlesei were predominant. Conclusion: Breeding density of acaroid mites was high in the stored rhizomatic traditional Chinese medicinal materials in Anhui province. This indicates that the traditional Chinese medicinal herbs of root-stock origins in storage are seriously contaminated by the acaroid mites, and such infestation should be positively controlled to reduce the potential harm to public health (AU)

Objetivo: investigar las especies y densidad de especies de ácaros en los productos a bases de raíces de la medicina tradicional china en la provincia de Anhui, China, con el fin de proporcionar evidencias para el control y la prevención de tal infestación. Métodos: se recogieron muestras de productos procedentes de raíces usados en la medicina tradicional china en 30 tiendas y almacenes de 17 ciudades de la provincia china de Anhui. Se recogieron las muestras mediante el embudo de Tullgren y la directicopia y los ácaros fueron identificados bajo microscopia. Resultados: se identifi caron 22 especies de ácaros, pertenecientes a 15 géneros menores de 5 familias a partir de 47 muestras almacenadas, en las que Tyrophagus putrescentiae, Acarus farinae, Carpoglyphus lactis y Cologlyplus berlesei eran predominantes. Conclusión: la densidad de ácaros fue alta en el las muestras a base de raíces en el material almacenado para usarse como remedio en la medicina tradicional china en la provincia de Anhui. El control de esta infestación puede reducir el daño potencial para la salud pública (AU)

Habitat use by Atherinella brasiliensis (Quoy & Gaimard, 1825) in intertidal zones of a subtropical estuary, Brazil / Uso do habitat por Atherinella brasiliensis (Quoy & Gaimard, 1825) nas regiões intertidais de um estuário subtropical, Brasil

Habitat use is different along the ontogenetic development of some species and may be influenced by environmental parameters. This study described the interaction of Atherinella brasiliensis caught in intertidal areas of the Paranaguá Estuarine Complex with environmental parameters. We caught 10024 individuals between August 2010 and July 2011, with total mean length of 44.32 mm (SD ± 25.37 mm), variation range between 12 and 142 mm, and weight between 0.01 and 73 g, averaging 1.35 g (SD ± 2.66 g) and ages estimated between 1 and 22 months. Significant differences were detected between sectors and periods for number of individuals and weight at capture, with higher mean values in the mean sector during the rainy period. The spatial and temporal distribution of ages was statistically different, individuals between 1 and 3 months were more abundant in the sector 2 during the rainy period, and individuals older than 7 months were evenly distributed throughout the sampling area, and with higher mean abundance at the beginning and end of the dry period. Environmental variables that most influenced the distribution of age classes were temperature and salinity.

O uso do habitat é diferenciado ao longo do desenvolvimento ontogenético em algumas espécies, podendo ser influenciado pelos parâmetros ambientais. O presente estudo descreve a interação da Atherinella brasiliensis capturada nas regiões intertidais do Complexo Estuarino de Paranaguá (CEP) com os parâmetros ambientais deste ambiente. Foram capturados 10024 indivíduos entre agosto de 2010 e julho de 2011, com comprimento total médio de 44,32 mm (DP = ± 25,37 mm), amplitude de variação entre 12 e 142 mm, e pesos entre 0,01 e 73 g, com média de 1,35g (DP = ± 2,66 g) e idades estimadas entre < 1 e 22 meses. Foram evidenciadas diferenças significativas entre setores e estações do ano no número de indivíduos e peso da captura, com maiores médias no setor mediano e na estação chuvosa. Diferenças estatísticas foram observadas na distribuição espaço-temporal das idades, com os indivíduos entre < 1 e 3 meses em média mais abundantes no setor 2 e período chuvoso, e os com indivíduos com idades acima de 7 meses igualmente distribuídos em toda a área amostral e com maior abundância média no início e final da seca. As variáveis ambientais que mais influenciaram na distribuição das classes etárias foram a temperatura e a salinidade.

Diagnóstico y propuestas comunitarias para el mejoramiento integral del barrio, el faro, comuna 8. Medellín / Diagnosis and community proposal for the integral improvement of the "el faro" neighborhood in the "8th" commune in Medellin

El presente texto presenta los resultados de un ejercicio investigativo. que visibiliza Por un lado las problemáticas más sentidas de los habitantes de las comunidades Golondrinas y El Faro de la Comuna 8 de la ciudad de Medellín, un ejercicio que se adelantó como respuesta ante los procesos de intervención institucional, derivados de los constantes procesos de transformación de la ciudad, los cuales, han generado desplazamientos y silencios frente a la realidad misma de dichas comunidades; por otro lado, presenta las propuesta de solución construidas desde las mismas comunidades ante dichos problemas.

This text presents: on the one hand, the results of an investigative exercise,which makes visible the deepest problems of the inhabitants of the communities swallows and the lighthouse of 8 commune of the city of Medellin, an exercise that be stepped forward in response to the process of institutional intervention arising from the constant processes of transformation of the city, which have led to displacement and rests with the same realities of those communities; on the other hand, it presents the proposal of solution built from the same communities face these problems.
