Can genetic rescue help save Arabia's last big cat?

Genetic diversity underpins evolutionary potential that is essential for the long-term viability of wildlife populations. Captive populations harbor genetic diversity potentially lost in the wild, which could be valuable for release programs and genetic rescue. The Critically Endangered Arabian leopard () has disappeared from most of its former range across the Arabian Peninsula, with fewer than 120 individuals left in the wild, and an additional 64 leopards in captivity.

16 Years of breed management brings substantial improvement in population genetics of the endangered Cleveland Bay Horse.

The consequences of poor breed management and inbreeding can range from gradual declines in individual productivity to more serious fertility and mortality concerns. However, many small and closed groups, as well as larger unmanaged populations, are plagued by genetic regression, often due to a dearth in breeding support tools which are accessible and easy to use in supporting decision-making. To address this, we have developed a population management tool (BCAS, Breed Conservation and Management System) based on individual relatedness assessed using pedigree-based kinship, which offers breeding recommendations for such populations.

Prey availability and intraguild competition regulate the spatiotemporal dynamics of a modified large carnivore guild.

Effective conservation management requires an understanding of the spatiotemporal dynamics driving large carnivore density and resource partitioning. In African ecosystems, reduced prey populations and the loss of competing guild members, most notably lion (), are expected to increase the levels of competition between remaining carnivores. Consequently, intraguild relationships can be altered, potentially increasing the risk of further population decline.

Minireview: Applications of NMR-based metabolomics for the detection and characterisation of toxoplasmosis in felids.

Toxoplasmosis is an infection caused by the intercellular protozoan parasite . The parasite has the three-stage life cycle: oocysts, tachyzoites, and bradyzoites. Felids are the only known hosts for the sexual reproduction of and, therefore, play a crucial role in the transmission of toxoplasmosis.
