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

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 ...

Using life history to predict outcomes of conservation translocations of herpetofauna

Animal Conservation, Volume 28, Issue 4, Page 592-606, August 2025.
We collected data on key life history traits for all herpetofauna profiled in the IUCN Global Conservation Translocation Perspectives series to examine how life history can predict outcomes and difficulties of conservation translocations. The relationships we found provide important insights for conservation practitioners that can be used in the ...
