The genetics of reintroduced addax populations in Tunisia: the first year of the project

In 2017 Marwell Wildlife began a 3-year project with Al Ain Zoo, the Royal Zoological Society of Scotland, San Diego Zoo Global and the Tunisian Direction Générale des Forêts to evaluate the genetic diversity of addax Addax nasomaculatus across global ex-situ populations and those reintroduced to Tunisia. The year one progress report for this project is now available from our publications-technical & project reports page.

Improving generation length estimates for the IUCN Red List

The International Union for the Conservation of Nature (IUCN) Red List classifies species according to their risk of extinction, informing local to global conservation decisions. In January we published a paper in PLOS One that looked to advance the estimation of generation lengths. Generation length estimates are used as a time-scalar in the Red List, as a way of accounting for differences in species’ life-histories. Overall, we provide a transparent, consistent and transferable approach for improving estimates of generation length for the Red List. This should help increase the accuracy of Red List assessments, especially when detailed life history data are missing.
