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...
The avifauna of Viruá National Park, Roraima, reveals megadiversity in Northern...
Laranjeiras, Thiago Orsi; Naka, Luciano Nicol?s; Bechtoldt, Catherine L.; Costa, Thiago Vernaschi Vieira da; Andretti, Christian BorgesWhile many published maps of avian species richness indicate northern Amazonia to be somewhat species-poor, recent surveys reveal that this area actually possesses one of the most species-rich avifaunas in the Neotropical lowlands. Our surveys indicate that at least 520 bird species occur in Viruá National Park (VNP) and adjacent areas, which is located in the Brazilian state of Roraima (northern Amazonia). Her...
One hundred and thirty-five years of avifaunal surveys around Santarém, central...
Lees, Alexander C.; Moura, Nárgila Gomes de; Andretti, Christian Borges; Davis, Bradley J.W.; Lopes, Edson Varga; Magalli Pinto Henriques, L.We present an updated annotated avifaunal checklist for the Santarém region of central Pará state, Brazil, an area that has one of the oldest histories of ornithological exploration in South America. We combine data from a fivemonth quantitative survey of the birds of the municipalities of Santarém and Belterra (east of the Tapajós River) between 2010 and 2011 with an exhaustive search of material in museum col...
Avian malaria, ecological host traits and mosquito abundance in southeastern Am...
Fecchio, Alan; Ellis, Vincenzo A.; Bell, Jeffrey Andrew; Andretti, Christian Borges; D'Horta, Fernando Mendonça; Silva, Allan M.; Tkach, Vasyl V.SUMMARY Avian malaria is a vector transmitted disease caused by Plasmodium and recent studies suggest that variation in its prevalence across avian hosts is correlated with a variety of ecological traits. Here we examine the relationship between prevalence and diversity of Plasmodium lineages in southeastern Amazonia and: (1) host ecological traits (nest location, nest type, flocking behaviour and diet); (2) de...
A social and ecological assessment of tropical land uses at multiple scales: Th...
Gardner, Toby Alan; Ferreira, Joice Nunes; Barlow, Jos; Lees, Alexander C.; Parry, Luke; Guimarães Vieira, Ima Cèlia; Berenguer, ErikaScience has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adopted by RAS offers...
