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 ...

Cytogenetic studies in Podocnemis expansa and Podocnemis sextuberculata (Testudines, Podocnemididae), turtles of the Brazilian Amazon [PDF]
Caryologia, 2011 Cytogenetic studies were conducted with Podocnemis expansa and Podocnemis sextuberculata, tur- tles of the Brazilian Amazon, aimed at a better characterization of the chromosomes of these species. To obtain mitotic chromosomes, lymphocytes were grown in a culture medium for karyotypes (RPMI), and harvested cells were treated to obtain metaphase ...

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.
