Pervasive gaps in Amazonian ecological research

Biodiversity 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...

Annotated checklist of the birds of Brazil by the Brazilian ornithological reco...

Since 2005, the Brazilian Ornithological Records Committee (CBRO) has published updated checklists of Brazilian birds almost every year. Herein, we present a completely new and annotated version of our checklist. For the first time, we list all bird subspecies known from Brazil that are currently accepted by at least one key ornithological reference work. The inclusion of the subspecies should be seen as a synt...

One hundred and thirty-five years of avifaunal surveys around Santarém, central...

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...

Brazil's environmental leadership at risk

Conducting rigorous avian inventories: Amazonian case studies and a roadmap for...

Site-based avian inventories are ubiquitous in Neotropical ornithology but are prone to error if fieldworkers are not familiar with the regional species pool, particularly in species-rich regions such as the Amazon basin. Here, we review recent species lists from the Brazilian Amazon in both the primary ornithological literature and in protected area management plans to assess the level of putative errors in te...

A social and ecological assessment of tropical land uses at multiple scales: Th...

Science 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...

Anthropogenic disturbance in tropical forests can double biodiversity loss from...

Concerted political attention has focused on reducing deforestation1,2,3, and this remains the cornerstone of most biodiversity conservation strategies4,5,6. However, maintaining forest cover may not reduce anthropogenic forest disturbances, which are rarely considered in conservation programmes6. These disturbances occur both within forests, including selective logging and wildfires7,8, and at the landscape le...

How pervasive is biotic homogenization in human‐modified tropical forest landsc...

Land-cover change and ecosystem degradation may lead to biotic homogenization, yet our under- standing of this phenomenon over large spatial scales and different biotic groups remains weak. We used a multi-taxa dataset from 335 sites and 36 heterogeneous landscapes in the Brazilian Amazon to examine the potential for landscape-scale processes to modulate the cumulative effects of local disturbances. Biotic homo...

Conducting rigorous avian inventories: Amazonian case studies and a roadmap for...

Inventários aviários baseados em locais são onipresentes na ornitologia neotropical, mas são propensos a erros se os pesquisadores de campo não estiverem familiarizados com o conjunto regional de espécies, particularmente em regiões ricas em espécies, como a bacia amazônica. Aqui, revisamos espécies recentes listas da Amazônia brasileira tanto na literatura ornitológica primária quanto em planos de manejo de ár...

Poor prospects for avian biodiversity in amazonian oil palm

A expansão das plantações de dendezeiros através dos trópicos úmidos precipitou a perda maciça de habitats de florestas tropicais e seus biotas speciose associados. Monoculturas de plantações de dendezeiros foram identificadas como uma ameaça emergente para a biodiversidade amazônica, mas Não há estudos quantitativos que explorem o impacto dessas plantações na biota do bioma. Compreensão esses impactos são extr...
