Wild Chimpanzee Welfare: A Focus on Nutrition, Foraging and Health to Inform Great Ape Welfare in the Wild and in Captivity

open access: yesAnimals, 2022
Adequate nutrition is essential for individual well-being, survival and reproductive fitness. Yet, in wild animals, including great apes, scoring nutrition or health comes with many challenges. Here, we have two aims: first, broadly review the scientific

Chimpanzee Kanako [PDF]

open access: yesPrimates, 2020
Chimpanzee societies generally show male philopatry and female dispersal. However, demographic data on wild chimpanzee societies from long-term study sites have revealed that some females give birth in their natal group (i.e., “remaining females”). Here, we report two remaining females in the M group in Mahale, Tanzania, and compare their cases with ...

Identification of Structural Variation in Chimpanzees Using Optical Mapping and Nanopore Sequencing. [PDF]

open access: yes, 2020
Recent efforts to comprehensively characterize great ape genetic diversity using short-read sequencing and single-nucleotide variants have led to important discoveries related to selection within species, demographic history, and lineage-specific traits.

Neuroanatomical correlates of individual differences in the object choice task in chimpanzees (Pan troglodytes)

open access: yesFrontiers in Psychology, 2022
Declarative and imperative joint attention or joint engagement are important milestones in human infant development. These have been shown to be a significant predictor of later language development and are impaired in some individuals with, or at risk ...
