Endangered Przewalski's horse, Equus przewalskii, cloned from historically cryopreserved cells

The paper reports the cloning of two endangered Przewalski's horse stallions from cryopreserved fibroblast cells, marking the first successful production of multiple healthy clones for an endangered species.

Unraveling the Genomic Diversity and Admixture History of Captive Tigers in the United States

This study analyzes the genomic diversity and admixture history of captive tigers in the U.S., finding admixture from all six wild tiger subspecies and developing a reference panel for conservation.

Historical population declines prompted significant genomic erosion in the northern and southern white rhinoceros (Ceratotherium simum)

The paper analyzes genomic changes in white rhinoceros subspecies before and after population declines, finding reduced genetic diversity and increased inbreeding in both.

How to make a rodent giant: Genomic basis and tradeoffs of gigantism in the capybara, the world’s largest rodent

This study sequenced the capybara genome to investigate the genetic basis of gigantism and related tradeoffs, finding elevated mutation load and novel anticancer mechanisms.
