Impacts of Climate Change on the Movement Ecology of an Imperfect Homeotherm
Biotropica, Volume 58, Issue 1, January 2026.ABSTRACT Rapid, human‐induced climate change has posed significant challenges to wildlife. One key strategy animals use to cope with environmental temperature fluctuations is behavioral thermoregulation. Understanding how climate change is expected to influence animal behavior is crucial for assessing its impact on species survival and informing ...

Social media videos highlight the impacts of the illegal use of snares on Brazilian biodiversity
People and Nature, Volume 7, Issue 11, Page 2811-2820, November 2025.Abstract Snares are one of the most used types of non‐selective traps for hunting worldwide, though their use is prohibited in many countries, including Brazil. Indiscriminate and unmonitored use of snares can induce serious conservation problems, particularly in megadiverse countries where higher species richness and diversity mean that the ...

Journal of Applied Ecology, Volume 62, Issue 8, Page 2036-2047, August 2025.The developed approach can be applied to several contexts to efficiently survey spatially aggregated populations using drone‐derived orthomosaics, and to understand phenology at these aggregation sites. We provide general recommendations for planning surveys and discuss implementations of our approach using other types of marking methods and model ...

Divergence Across Niche Dimensions Reveals Species' Ecological Roles
Ecology Letters, Volume 28, Issue 7, July 2025.Natural history gaps hinder our understanding of species' ecological roles and their contributions to ecosystem processes. Using an integrative framework, we analysed multiple niche dimensions of co‐occurring xenarthran insectivores, revealing divergent trophic, spatial and temporal patterns that reflect distinct ecological roles. Our results challenge

Counting animals in orthomosaics from aerial imagery: Challenges and future directions
Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1051-1060, June 2025.Abstract The use of drones to survey and monitor wildlife populations has increased exponentially. A common protocol used for data collection is planning flights with substantial overlap between successive photographs and lateral lines and then creating orthomosaics by merging the collected images.
