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...

Avifauna of the upper Purus River: relevant records for an area lacking ornitho...
Godoy, Fernando Igor de; Guilherme, Edson; Pedroza, Diego; Plácido, Ricardo Antônio de AndradeBirds are the best-known vertebrate group, although many localities in the world are considered to be knowledge gaps. This is the case of many little-known environments in the Amazon biome, the world’s largest tropical forest. Here, we present a survey of birds in the upper Purus basin, comprising the municipalities of Manoel Urbano and Feijó in the Brazilian state of Acre, and Boca do Acre and Pauini in the st...

Souza, Jesus Rodrigues Domingos de; Andrade Plácido, Ricardo Antônio de; Guilherme, Edson; Melo, Tomaz Nascimento deThe Brazilian endemic species Pyrrhura lucianii Deville, 1851, was found on private property in the municipality of Senador Guiomard in Acre State, Brazil. This is the first record of this parakeet species in the state, expanding its distribution in 219 km to the south of Pauini, the nearest location. The species was observed consuming salt, used as a cattle feed supplement. © Souza et al.
Bird-plant interactions on the edge of a forest fragment in southwestern Brazil...
Alencar, Luana; Guilherme, EdsonSeed dispersal is one of the principal ecological processes that determine the richness and distribution of plants in tropical forests. Birds play an important role in the zoochoric dispersal of seeds in these forests. The present study investigated the bird-plant interactions involving the ingestion and dispersal of seeds by the birds found in the edge habitat of an isolated forest fragment on the Catuaba Expe...

Tobias, Joseph A.; Lebbin, Daniel J.; Aleixo, Alexandre Luis Padovan; Andersen, Michael J.; Guilherme, Edson; Hosner, Peter A.; Seddon, NathalieThe Rufous Twistwing (Cnipodectes superrufus), a newly described Amazonian tyrant-flycatcher, is known from five specimens and five localities in Cuzco and western Madre de Dios departments, Peru. We report three additional specimens and eight new localities extending the known range of the species east across Dpto. Madre de Dios, Peru, into Dpto. Pando, Bolivia, and Acre State, Brazil.
