Mapping priority areas to mitigate the risk of electrocution of range‐restricted bird species

Journal of Applied Ecology, Volume 62, Issue 10, Page 2787-2799, October 2025.
Our study proposes a framework to identify areas with higher electrocution risk, which can be used even in data‐scarce regions or adapted to a multi‐species assessment context. This approach can support proactive strategies for energy companies with an initial assessment identifying areas to avoid installing new power lines, evaluating sites for ...

Canonical transformation for stiff matter models in quantum cosmology

, 2010
In the present work we consider Friedmann-Robertson-Walker models in the presence of a stiff matter perfect fluid and a cosmological constant. We write the superhamiltonian of these models using the Schutz's variational formalism.

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.
