Article Synopsis
- Scientists study how animals change to survive in different places, which is really important for understanding biology.
- They looked at chimpanzees, our closest relatives, who live in many types of environments like rainforests and savannahs.
- By examining genetic information from wild chimpanzees, they discovered that some chimps have adapted to fight off malaria in similar ways to humans, showing how important genetic diversity is for endangered animals.
Article Synopsis
- This study provides the first comprehensive catalog of chimpanzee genetic diversity using non-invasive samples collected from 48 sites in Africa, focusing on chromosome 21.
- The research reveals clear genetic differences among the four recognized chimpanzee subspecies and indicates unexpected local genetic exchanges, while also mapping patterns of population isolation, migration, and connectivity.
- Unlike humans, chimpanzees lack a history of long-distance migrations, which may affect their cultural transmission, and the study introduces a precise geolocation method for identifying the origins of confiscated chimpanzees.
Paleoclimate reconstructions have enhanced our understanding of how past climates have shaped present-day biodiversity. We hypothesize that the geographic extent of Pleistocene forest refugia and suitable habitat fluctuated significantly in time during the late Quaternary for chimpanzees (Pan troglodytes). Using bioclimatic variables representing monthly temperature and precipitation estimates, past human population density data, and an extensive database of georeferenced presence points, we built a model of changing habitat suitability for chimpanzees at fine spatio-temporal scales dating back to the Last Interglacial (120,000 BP).

- * Researchers analyzed fecal immunoglobulin A antibodies in bonobos to determine their exposure to various human respiratory viruses, finding a notable presence of antibodies against multiple viruses.
- * The findings suggest a need for a strategic action plan based on epidemiological data to better protect bonobos from these anthropozoonoses.
Malaria parasites, though widespread among wild chimpanzees and gorillas, have not been detected in bonobos. Here, we show that wild-living bonobos are endemically Plasmodium infected in the eastern-most part of their range. Testing 1556 faecal samples from 11 field sites, we identify high prevalence Laverania infections in the Tshuapa-Lomami-Lualaba (TL2) area, but not at other locations across the Congo.
