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

open access: yesWildlife 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 ...

Isotopic evidence for the consumption of Galliformes by the red fox (Vulpes vulpes) in rural southern England

open access: yesWildlife Biology, EarlyView.
Anthropogenic resource subsidies can drive mesopredator population growth, altering predator–prey dynamics. The red fox Vulpes vulpes is a generalist canid that can readily exploit such subsidies. In the UK, tens of millions of pheasants Phasianus colchicus and red‐legged partridges Alectoris rufa are released annually for sport shooting, potentially ...

A Case Report on Rehabilitation of the Asiatic Black Bear (Ursus thibetanus ussuricus) in the Wild 亚洲黑熊 (Ursus thibetanus ussuricus) 野外放归野化案例报告

open access: yesWildlife Letters, EarlyView.
Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

open access: yesWildlife Monographs, EarlyView.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Chronic Wasting Disease management responses in North America: A public policy analysis

open access: yesWildlife Society Bulletin, EarlyView.
In this study we use the Multiple Streams Framework from public policy theory to assess the responses of wildlife management agencies in states and provinces with CWD‐positive cases in the United States and Canada to alleviate public concerns and manage the spread of this disease.

Finding Mr. Right: Housing Quality Affects Male Mouse Attractiveness to Females, With Implications for Conservation Captive Breeding

open access: yesZoo Biology, EarlyView.
Housing quality affects male mouse attractiveness to females ABSTRACT Females generally prefer mates with traits indicating low stress (e.g., large size; good health). In captivity, stress from suboptimal housing might therefore reduce male attractiveness.

Evaluation of the Sex and Species Distribution, Breeding, and Life Expectancy of Zoo‐Housed Chameleons

open access: yesZoo Biology, EarlyView.
ABSTRACT More than a third of the 202 identified chameleon species are classified as “vulnerable” or “critically endangered”. No data is available regarding the life expectancy of chameleons kept in zoos. The objectives of this study were to determine the sex and species distribution of chameleons kept in zoological institutions, and to assess their ...

Dietary and Ranging Behavior of Semi‐Free Ranging Lemur catta and Varecia rubra at Myakka City Lemur Reserve, Florida, USA

open access: yesZoo Biology, EarlyView.
Betsiboka, a female red ruffed lemur (Varecia rubra) eating Carolina redroot in the Tower forest. ABSTRACT Lemurs are severely threatened due to anthropogenic habitat loss and climate change. Therefore, understanding how lemurs adapt their diets to novel habitats is critically important for maintaining healthy wild populations and effectively managing ...

Limited Effects of Temperature on Captive Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis) Growth

open access: yesZoo Biology, EarlyView.
While higher temperatures are generally expected to increase amphibian growth, our experiments with captive‐reared Eastern Hellbenders found no evidence that growth increased at a rearing temperature of 21°C relative to 16°C. As Eastern Hellbender reintroduction efforts move forward, a focus on other conditions, such as density or diet, might be more ...
