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...
Small forest losses degrade stream macroinvertebrate assemblages in the eastern...
Brito, Janaina G.; Roque, Fabio O.; Martins, Renato Tavares; Nessimian, Jorge; Oliveira, Vívian Campos de; Hughes, Robert MasonGenerally, habitat loss and fragmentation negatively affect biota, often in nonlinear ways. Such nonlinear responses suggest the existence of critical limits for habitat loss beyond which taxa experience substantial changes. Therefore, we identified change points for aquatic macroinvertebrate assemblages at both local-riparian and catchment extents in response to a forest-loss gradient in agriculture-altered la...
Influence of habitat and land use on the assemblages of Ephemeroptera, Plecopte...
Monteiro do Amaral, Pedro Henrique; Silveira, Lidimara Souza da; Rosa, Beatriz Figueiraujo Jabour Vescovi; Oliveira, Vívian Campos de; Alves, R. G.Insects of the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT) are often used to assess the conditions of aquatic environments, but few studies have examined the differences in these communities between riffles and pools. Our objective was to test whether riffles shelter greater richness and abundance of EPT, as well as to assess the sensitivity of these insects for detecting impacts from different land...
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...
Macroinvertebrados associados a folhiço em um córrego de Mata Atlântica no sude...
Oliveira, Vívian Campos deCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior; Essa dissertação foi dividida em duas partes, sendo que a primeira trata-se de um estudo sobre a fauna de Ephemeroptera, Plecoptera e Trichoptera associada a mesohabitat de folhiço em um córrego de mata Atlântica no sudeste do Brasil. Este estudo teve como objetivo avaliar a composição e a distribuição espacial e temporal da fauna de Ephemerop...
