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 ...

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 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 ...

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 ...

Several biotic and abiotic factors may influence species distribution patterns. Montane environments may represent barriers to species dispersal, especially in the tropics where isolation and allopatric speciation are ...

Acalypha L. is the third largest genus of Euphorbiaceae, with approximately 450 species. The genus is represented on almost all continents and its greatest diversity is reported to the Neotropics. In Brazil, Acalypha has ...

Tanto os fatores abióticos como bióticos influenciam a reprodução de anuros. Entre os abióticos, a temperatura e precipitação são os principais determinantes do período reprodutivo desses animais. Em anuros com reprodução ...

Although the processes involved in searching, digestion and absorption of the food involve high energy investment, the low maintenance cost of some ectothermic vertebrates allows feeding to occur at irregular intervals. ...

Evidence denote that positive interactions between plants (i.e. facilitation) are more frequent in environments under severe environmental conditions. In addition to the benefits resulting from improved environmental ...
