Governance and infrastructure as pillars of performance: A socio‐ecological analysis of Ethiopian botanical gardens

PLANTS, PEOPLE, PLANET, EarlyView.
While botanical gardens are often perceived merely as recreational spaces for a weekend walk, in the Global South, they are true lifelines for nature and for the people who depend on it. Our research in Ethiopia explored what actually keeps these gardens running long‐term.

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 ...

Ex Situ Conservation of Plant Genetic Resources: Global Development and Environmental Concerns

Conservation of plant genetic resources is achieved by protection of populations in nature (in situ) or by preservation of samples in gene banks (ex situ). The latter are essential for users of germplasm who need ready access.

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

Wildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

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

Zoo 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 ...
