Digest: From diversity to a single species-evolutionary dynamics of Antilocapridae
1Wildlife Ecology and Conservation, Wageningen University, Wageningen, The Netherlands.
Abstract:
The evolutionary dynamics of species over time are influenced by the interaction of biotic and abiotic factors. Nascimento & Pires (2025) explored which factors shaped the evolution of Antilocapridae over time. The single extant species of Antilocapridae, Antilocapra americana, diverged from previously diverse clades, Merycodontinae and Antilocaprinae, seemingly displacing the former. The authors found that speciation and extinction rates of these groups were associated with changes in ecosystems, the richness of competitive species, and the richness of felid predators.
