Two-toed sloth (Choloepus ssp.) ex-situ population genomic-informed management

This project focuses on the ex-situ population of two-toed sloths (Choloepus didactylus and Choloepus hoffmani) found in Europe's zoos, comprising nearly 300 individuals. Recent genomic data identified at least four distinct wild lineages within the Choloepus genus, requiring a reassessment of breeding practices. The project aims to analyse the population genomics of the captive population and provide recommendations to optimise genetic diversity, ensuring its long-term sustainability.

With nearly 300 individuals across two recognized species (Choloepus didactylus and Choloepus hoffmani), the EAZA ex-situ population of two-toed sloths represents a valuable resource for conservation. However, emerging genomic data revealing at least four distinct wild lineages within the Choloepus genus necessitates a reassessment of current management practices. This project aims to determine the genomics composition of the captive population and develop informed recommendations for breeding strategies, optimising genetic diversity and contributing to the long-term sustainability of two-toed sloths in zoos.
