The human malaria parasite Plasmodium falciparum evolved from a parasite that infects gorillas, termed Plasmodium praefalciparum. The sialic acids on glycans on the surface of erythrocytes differ between humans and other apes. It has recently been shown that the P.

The nature of western lowland gorilla social relationships within and between groups is largely understudied, partly due to the challenges of monitoring associations between individuals who live in neighboring groups. In this study, we examined the social relationships of four western lowland gorilla groups in the Ndoki landscape of northern Republic of Congo. To do so, we compiled all-occurrence social interaction and silverback nearest neighbor social networks from data collected during daily group follows conducted over several years.

Animals commonly form dominance relationships that determine the priority of access to resources and influence fitness. Dominance relationships based on age, immigration order or nepotism (alliances with kin) conventions are usually more stable than those based on intrinsic characteristics such as physical strength. Unlike most mammals, female gorillas disperse from their groups, typically more than once in their lifetimes, disrupting their group tenures and/or any alliances.

T cells recognize peptides displayed on the surface of cells on MHC molecules. Genetic variation in MHC genes alters their peptide-binding repertoire and thus influences the potential immune response generated against pathogens. Both gorillas and chimpanzees show reduced diversity at their MHC class I A (MHC-A) locus compared to humans, which has been suggested to be the result of a pathogen-mediated selective sweep.

Poor sleep quality has been linked to both poor psychological and physical well-being. Mood and anxiety levels are affected by poor quality sleep, and the relationship between these variables appears to be mediated by a tendency to depersonalize or not. This study examines these relationships in 112 Adults (Female = 82, Male = 30), via an online study.
