Relation between small-mammal species composition and anthropic variables in the Brazilian Atlantic Forest

, : Relation between small-mammal species composition and anthropic variables in the Brazilian Atlantic Forest. Brazilian Journal of Biology 65(3): 495-501

Anthropic activities are frequently related in many ways to forest fragmentation and alteration of natural communities. In this study, we correlate the presence of hunting, tourism activity, agriculture/pasturing, and the distance of the study sites to the nearest human residences with the species composition of small Atlantic forest mammals. To do this, we utilize a multiple regression analysis of similarity matrices. The presence of both agriculture/pasturing and human residences near the study sites proved to be determinant factors in species composition of small mammals of the studied areas. Working with socioeconomic variables related directly with the study site could be a reliable and a direct way to predict the influence of human presence and entailed activity on small mammal communities.

We have previously reported anti-obesity effects ofLysimachia foenum-graecumin high-fat diet (HFD)-induced obesity model. Here we isolated a triterpene saponin foenumoside B as an active component ofL. foenum-graecum. Foenumoside B blocked the dif...

A short peptide derived from the C-terminal region of Bothrops asper myotoxin II, a Lys49 phospholipase A2 (PLA2), was previously found to reproduce the bactericidal activity of its parent molecule. In this study, a panel of eight PLA2 myotoxins p...
