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...
Disentangling the pathways of land use impacts on the functional structure of f...
Leitão, Rafael Pereira; Zuanon, Jansen; Mouillot, David; Leal, Cecília Gontijo; Hughes, Robert Mason; Kaufmann, Philip Robert; Vill?ger, S?bastienAgricultural land use is a primary driver of environmental impacts on streams. However, the causal processes that shape these impacts operate through multiple pathways and at several spatial scales. This complexity undermines the development of more effective management approaches, and illustrates the need for more in-depth studies to assess the mechanisms that determine changes in stream biodiversity. Here we ...
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...
