Malaria diagnosis under field conditions in the Venezuelan Amazon.

, 2008
To improve practical, accurate diagnosis of malaria in the Amazon rainforest of Venezuela, two rapid diagnostic tests (RDT) (OptiMAL-IT) and FalciVax) and a laboratory light microscope, used in the field with a battery-operated head lamp as an external ...

Protected areas on international borders show uneven conservation outcomes

Conservation Biology, EarlyView.
Abstract Border protected areas (BPAs) are national protected areas that are immediately adjacent to a country's border or span two or more countries; they are characterized by distinctive opportunities and pressures. They play a critical role in protecting carbon‐rich ecosystems, conserving endangered biodiversity, reducing cross‐border environmental ...

A framework for integrating resilience indicators into risk assessments

Conservation Biology, EarlyView.
Abstract Globally, ecosystems are increasingly threatened by climate change and human pressures, yet ecosystem risk assessments predominantly emphasize exposure to stressors while overlooking intrinsic ecosystem resilience—the capacity to absorb and recover from disturbances.

Characteristics of rainfall in the Brazillian Amazon Basin

, 2000
The intent of this paper is to present the hypothesis that the influence of sea surface temperature (SST) on rainfall in the Brazilian Amazon Basin is largely through is influence on onset and end of the rainy season, rather than on rain rates during the

Effects of climate change on marine biodiversity on the western Atlantic coast

Conservation Biology, EarlyView.
Abstract The current climate crisis, driven by greenhouse gas emissions, threatens global biodiversity, including that in marine ecosystems. However, projections for the western Atlantic Ocean that jointly quantify species richness and endemism while accounting for spatially biased and incomplete occurrence data remain limited.

Cryptic diversity highlights the challenge of Linnean and Wallacean shortfalls and the integral role of taxonomy in biodiversity conservation

Conservation Science and Practice, EarlyView.
Abstract Reliable and current taxonomic data are essential to conservation planning and prioritization. The use of genetic and genomic tools has revealed significant cryptic diversity across taxa and ecosystems, suggesting we are underestimating threatened biodiversity and using outdated species distributions.

Challenges to managing ecosystems sustainably for poverty alleviation: Securing well-being in the Andes/Amazon [PDF]

, 2008
This report focuses on the Amazon basin and the eastern Andean slopes (herein referred to as the Andes/Amazon ecosystem or region). The Amazon is the largest fresh water system and tropical forest in the world.

The Western Amazon, key to the Amazon Basin

Infographic From human to ecological dimensions, the Western Amazon represents a central region for the Amazon Basin. It is home to 27.7 million people, hosts 74% of Amazonian fish species, and plays a fundamental role in aquatic connectivity and the flow of Andean sediments to the Amazon and the Atlantic.

Hydropower Regulation of Xingu River Discharge Structures Heterogeneous, Sector‐Specific Responses in Pacu Fisheries Along the River Continuum

Fisheries Management and Ecology, EarlyView.
ABSTRACT Hydroelectric dams are common in Amazonian tributaries under federal environmental licensing that requires long‐term fisheries monitoring. This study evaluated three fishing systems targeting “pacu” species (Serrasalmidae) in the Xingu River before, during, and after construction of the Belo Monte dam (2012–2023) across four river sectors ...

Fire‐driven forest degradation enhances termite activity and accelerates litter decomposition in the Amazonia rainforest

Insect Conservation and Diversity, EarlyView.
Forest degradation increased termite‐mediated litter decomposition, whereas no such effect was detected in undisturbed forests. Reduced ant predation and altered forest conditions were associated with higher termite abundance and faster litter decomposition.
