Past Connectivity but Recent Inbreeding in Cross River Gorillas Determined Using Whole Genomes from Single Hairs.

The critically endangered western gorillas () are divided into two subspecies: the western lowland () and the Cross River () gorilla. Given the difficulty in sampling wild great ape populations and the small estimated size of the Cross River gorilla population, only one whole genome of a Cross River gorilla has been sequenced to date, hindering the study of this subspecies at the population level. In this study, we expand the number of whole genomes available for wild western gorillas, generating 41 new genomes (25 belonging to Cross River gorillas) using single shed hairs collected from gorilla nests.

Suspected Sunda clouded leopard (Neofelis diardi) predation attempts on two reintroduced Bornean orangutans (Pongo pygmaeus wurmbii) in Bukit Batikap Protection Forest, Central Kalimantan, Indonesia.

In February 2017 and August 2018, respectively, two Bornean orangutans (Pongo pygmaeus wurmbii) reintroduced into the Bukit Batikap Protection Forest in Central Kalimantan were found in weakened physical condition and with deep puncture wounds. The first individual was a sub-adult male, and the second an adult female whose 6- to 8-week-old infant was missing. Both individuals were rescued and transported back to the field base camp for treatment.
