Escarabajos coprófagos (Coleoptera: Scarabaeinae) asociados a excrementos de mamíferos en un fragmento de bosque seco tropical en el Departamento del Atlántico, Colombia
Provedor de dados: 67
La expansión agrícolo-ganadera puede afectar de manera indirecta a la fauna nativa. Debido a esto se evaluó la composición y la estructura de escarabajos coprófagos asociados a excrementos de Alouatta seniculus, Sus domestica y Bos taurus en un fragmento de bosque seco tropical en la Reserva Campesina Tierra Arena (RCTA), Atlántico. Se realizaron cuatro muestreos entre junio y octubre de 2008. Se marcaron 10 puntos distanciados 50 m y en cada uno se colocaron en posición triangular tres trampas de caída, cebadas por separado con excremento de los mamíferos mencionados. Las trampas fueron revisadas a las 24 horas. Se recolectaron 864 individuos agrupados en 21 especies y nueve géneros, destacándose Uroxys sp. con 33.21% del total de individuos capturados....

Community composition and species richness of parasitoids infesting Yponomeuta species in the Netherlands
Provedor de dados: 16
Autores: Cleary, Daniel F.R.
Parasitoid assemblages infesting Yponomeuta species in the Netherlands were investigated. Parasitoid species richness and community composition were related to host species, habitat, temporal and spatial variation. Both community structure and species richness did not differ among habitats. There was no significant difference in species richness between years (1994 and 1995) but there was a significant difference in community composition. Community composition and species richness both differed among host species, although this latter result was solely due to the host species Y. evonymellus. There was no significant relationship between community similarity and distance. These results indicate that the parasitoids of the moth genus Yponomeuta in the...

The influence of environmental variables on the functional structure of headwater stream fish assemblages: a study of two tropical basins in Central Brazil
Provedor de dados: 83
Autores: Carvalho,Rodrigo Assis; Tejerina-Garro,Francisco Leonardo.
We investigated functional patterns of fish assemblages of two adjacent basins (Araguaia and Tocantins) to test whether their headwater stream fish assemblages are more functionally (dis)similar than expected by chance and whether these (dis)similarities are related to differences of environmental conditions between basins. We used an analysis of similarities (ANOSIM) on a functional dissimilarity matrix to test for (dis)similarities between fish assemblages of both basins. We performed RLQ and fourth-corner analyses to determine fish species trait-environment relationship. Our results revealed functional dissimilarities between fish assemblages of both basins and significant species trait-environment relationships, suggesting that environmental conditions...
