Geographic distribution models and conservation status of two endangered species of Rhipsalis (Cactaceae) in the Atlantic Forest. The Rhipsalis (Cactaceae) is the most abundant genus among all the epiphytic cactus. This ...

The mountains of the Brazilian Atlantic Forest have a high degree of endemism and its biogeographical history is poorly explored. One hypothesis for the diversification of montane organisms, related to the refuge theory, ...

O período e a duração do ciclo reprodutivo dos anuros estão frequentemente relacionados a estrutura do habitat e às condições climáticas. Espécies que ocorrem em corpos d'água permanentes geralmente possuem período ...

Biological diversification generates patterns of genetic diversity, be it driven by neutral biogeographic (variance and dispersal) or populational (demographic fluctuation) or even adaptive processes mediated by natural ...

Sexual size dimorphism is widely studied in mammals. Its magnitude and direction present large variation among species, since there are different selective forces acting on each sex. Besides, how altitude and other climatic ...

It is estimated that in Brazil there are between 4,000 and 6,000 species of Heteroptera, however, knowledge about the regional fauna is still limited. For the state of São Paulo, the knowledge of the fauna of Heteroptera ...

There are some extremely biodiverse regions in South America such as the Andes, the Amazon and the Atlantic Forest. The historical processes that originated and maintain such diversity are still not fully understood. Our ...

Macroecology focuses on the relationship between organisms and their environments in broad spatial and temporal scales. One of its approaches is the analysis of geographical patterns in the morphological traits. Several ...
