Pervasive gaps in Amazonian ecological research
Carvalho, Raquel L.; Resende, Angelica F.; Barlow, Jos; França, Filipe M.; Moura, Mario R.; Maciel, Rafaella; Alves-Martins, Fernanda; Shutt, JackBiodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...
Natural mass movements in Serra do Divisor in the far west of the Western Amazon
Silva, Sonaira Souza da; Nascimento, Eric de Souza; Almeida, Marllus Rafael Negreiros de; Koga, Diogo Mitsuru; Melo, Antonio Willian Flores deMass movements, also known as landslides, landslides and erosions, cause the soil to break down and transport, caused by natural factors such as precipitation, earthquakes or winds. These events have environmental and/or social impacts, depending on the geographic context in which they are inserted.

Orchid bees of forest fragments in Southwestern Amazonia
Storck-Tonon, Danielle; Morato, Elder Ferreira; Melo, Antonio Willian Flores de; Oliveira, Marcio Luiz deBees of the tribe Euglossini are known as orchid-bees. In general, areas with more vegetation cover have greater abundance and diversity of these bees. This study investigated the effects of forest fragmentation on assemblages of the euglossine bees in the region of Rio Branco municipality, State of Acre, and surrounding areas. Ten forest fragments with varying sizes were selected for the study and were classif...
