Forty years of captive breeding in Przewalski's horse: pedigree‐based insights into population growth, sex ratio, and inbreeding

Wildlife Biology, EarlyView.
Long‐term captive breeding programs play a critical role in the conservation and reintroduction of endangered species, yet they face persistent challenges related to demographic structure and genetic management. The Przewalski's horse Equus przewalskii, once extinct in the wild, represents a global model for conservation breeding supported by pedigree ...

Soil and microbial responses to wild ungulate trampling depend more on ecosystem type than trampling severity

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...
