The Atlantic Forest is considered one of the world's hotspots of biodiversity and, even with the growing threat to its ecosystems, has a high level of biological diversity and endemism. Euphorbiaceae is one of the largest, ...

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 ...

The insects of Pentatomidae Family are known to have some pests that cause damage to crop. There are approximately 5.000 species, which 70 are pests and 24 occur in the Neotropical region. We can detach three main species ...

Several arthropod species use chemicals to detect sexual partners. In harvestmen (Arachnida, Opiliones) there are evidences that chemicals have an important role in intra-specific communication. Using the behavior of ...

The landscape functional connectivity reduction can be caused by fragmentation processes, habitat loss, and anthropogenic activities of different types and intensities in the matrix. The pasture areas are examples of these ...

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, ...

The diversity of habitats along a geographic gradient imposes selective pressures that result in differences in the life history of individuals of the same species. In ectothermal animals, such as anuran amphibians, climatic ...

The evidence of acoustic variation among animal populations has inspired scientists to inquire about the evolutionary and ecological mechanisms that shape the divergence of songs and that have led to the emergence of ...

As formações campestres do Cerrado ainda são pouco valorizadas, apesar de possuírem alta riqueza e diversidade de espécies vegetais, com características únicas para sobreviverem em um ambiente oligotrófico com perturbações ...

This study aims to investigate spatio-temporal dynamics of Ariíds Cathorops spixii (Cs) and Genidens genidens (Gg), in which the hypothesis was tested to verify if the groups of individuals of C. spixii have the same pattern ...
