Tracking the impacts of El Niño drought and fire in human-modified Amazonian fo...
Berenguer, Erika; Lennox, Gareth D.; Ferreira, Joice; Malhi, Yadvinder; Aragão, Luiz E.O.C.; Barreto, Julia Rodrigues; Del Bon Espírito-Santo, FernandoMade available in DSpace on 2022-04-28T19:42:03Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-07-27; With humanity facing an unprecedented climate crisis, the conservation of tropical forests has never been so important – their vast terrestrial carbon stocks can be turned into emissions by climatic and human disturbances. However, the duration of these effects is poorly understood, and it is unclear wh...
BIOFRAG - a new database for analyzing BIOdiversity responses to forest FRAGmen...
Pfeifer, Marion; Lefebvre, Véronique; Gardner, Toby Alan; Arroyo-Rodríguez, Víctor; Baeten, Lander; Banks-Leite, Cristina; Barlow, JosHabitat fragmentation studies have produced complex results that are challenging to synthesize. Inconsistencies among studies may result from variation in the choice of landscape metrics and response variables, which is often compounded by a lack of key statistical or methodological information. Collating primary datasets on biodiversity responses to fragmentation in a consistent and flexible database permits s...
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...
Quantifying the biodiversity value of tropical primary, secondary, and plantati...
Barlow, Jos; Gardner, Toby Alan; Araújo, Ivanei Souza; Ávila-Pires, Teresa Cristina Sauer; Bonaldo, Alexandre Bragio; Costa, Joana E.Biodiversity loss from deforestation may be partly offset by the expansion of secondary forests and plantation forestry in the tropics. However, our current knowledge of the value of these habitats for biodiversity conservation is limited to very few taxa, and many studies are severely confounded by methodological shortcomings. We examined the conservation value of tropical primary, secondary, and plantation fo...
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...
Biodiversity consequences of land-use change and forest disturbance in the Amaz...
Solar, Ricardo Ribeiro de Castro; Barlow, Jos; Andersen, Alan N.; Schoereder, José H.; Berenguer, Erika; Ferreira, Joice N.; Gardner, Toby AlanQuantifying and understanding the main drivers of biodiversity responses to human disturbances at multiple scales is key to foster effective conservation plans and management systems. Here we report on a detailed regional assessment of the response of ant communities to land-use change and forest disturbance in the Brazilian Amazon. We aimed to explore the effects of land-use intensification at both site and la...
Soil Organic Matter Responses to Anthropogenic Forest Disturbance and Land Use ...
Durigan, Mariana Regina; Cherubin, Maurício Roberto; Camargo, Plínio Barbosa de; Ferreira, Joice Nunes; Berenguer, Erika; Gardner, Toby AlanA perturbação florestal antropogênica e a mudança no uso da terra(LUC) na região amazônica são principal fonte de emissões de gases de efeito estufa para a atmosfera no Brasil, devido ao carbono (C)e nitrogênio (N) emitido da limpeza da vegetação. Conversão de uso da terra associada à gestão práticas desempenham um papel fundamental na distribuição e origem de C em diferentes matérias orgânicas do solo (MOS)fra...
