Estimating abundance of aggregated populations with drones while accounting for multiple sources of errors: A case study on the mass nesting of Giant South American River Turtles

open access: yesJournal 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 ...

The Wildity Scale as a management tool for reintroduced specimens

open access: yesEcological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
Mexican wolves and other species are dispersing in the wild under human‐controlled ecological conditions. The concept and scale of wildity were developed as management tools for reintroduced specimens and context‐specific scenarios. Technological advances and the challenges of the Anthropocene require new communication strategies to support coexistence.

Restricted Dispersal in the Late Successional Forest Tree Species Nothofagus Pumilio: Consequences Under Global Change

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
We aim to uncover the current and historic effective dispersal distances and characterize fine‐scale genetic structure in the forest tree species Nothofagus pumilio. Short seed dispersal distances mean N. pumilio distribution expansion capacity may be limited, especially in the context of global change.
