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 ...

Potential Adaptive Introgression From Dogs in Iberian Grey Wolves (Canis lupus)
Molecular Ecology, Volume 34, Issue 12, June 2025.ABSTRACT Invading species along with increased anthropogenization may lead to hybridization events between wild species and closely related domesticates. As a consequence, wild species may carry introgressed alleles from domestic species, which is generally assumed to yield adverse effects in wild populations.
