Racing Amidst Change: Urbanization and Climate Alter Functional Traits and Distribution of an Amazonian Parthenogenetic Lizard

Biotropica, Volume 57, Issue 5, September 2025.
By comparing native and neonative populations of an Amazonian lizard, we examine how urban environments and climate change impact its functional traits, while also predicting its future distribution. Our findings offer insights into how some species may adapt to human‐altered landscapes, showing that not all are negatively affected by these changes ...

Biases in Amphibian Sampling in the Amazon: Using Infrastructure and Accessibility Data to Identify Sampling Gaps

Biotropica, Volume 57, Issue 5, September 2025.
Biogeographic knowledge of Amazonian amphibians is constrained by spatial and temporal coverage, leading to biases that affect the understanding of their diversity patterns. Using an extensive occurrence database, this study identified knowledge gaps and sampling biases linked to infrastructure and accessibility factors across the region.

Surviving in the Amazon Arc of Deforestation: Richness and Defaunation of Mammals in Priority‐Protected Areas of the Brazilian Midwest

Austral Ecology, Volume 50, Issue 7, July 2025.
We found rich and compositionally different assemblages of medium and large‐sized mammals in protected areas on the southern edge of Amazon. However, both have high rates of mammal defaunation. We argue that anthropogenic threats in the Amazon Arc of Deforestation are eroding large ungulate populations, especially peccaries.
