AbstractFemale dominance relationships were studied among three family groups of western lowland gorillas (Gorilla gorilla gorilla) housed in large enclosures at Howletts Wild Animal Park, in Kent, England. In common with gorillas in their natural habitat, the Howletts gorillas forage throughout the day on low nutrient foods. However, the latter differ, at least from mountain gorillas (Gorilla gorilla beringei), in that they also have relatively frequent access to high nutrient, high energy novel food items which are patchily distributed in time and space, and defendable. It was predicted that, despite these differences, the Howletts females would resemble mountain gorillas in forming adult female dominance hierarchies (determined from supplant interactions) in which older females that have lived in the group the longest are dominant to younger females, more recent to the group. The comparison was made with mountain gorillas as they are the only gorilla subspecies for which such data exist for wild-living populations. As predicted, an age/tenure-based dominance hierarchy was found to be the case for those groups at Howletts where there was considerable variation between the females' ages and length of group tenure. As gorillas and chimpanzees resemble more closely each other in forming age/tenure-based dominance hierarchies than they do other female-transfer primate species, it is proposed that the gorilla-chimpanzee pattern may have common phylogenetic origins. In addition, the order of progression of gorillas into their indoor living quarters appears to be a good indicator of supplant-dominance relationships among adult group members. It was also found that, despite being removed from their natural habitat, dominant males in captivity still lead their groups during group travel in the same manner that do males in the wild: either at the head, or bringing up the rear. Though primate social behaviour may be flexible depending on immediate context and life history variables, this flexibility may well remain within evolutionarily defined parameters, leading to species-typical patterns in general social interactions.

Allostatic load, or the physiological dysregulation accumulated due to senescence and stress, is an established predictor of human morbidity and mortality and has been proposed as a tool for monitoring health and welfare in captive wildlife. It is estimated by combining biomarkers from multiple somatic systems into allostatic load indices (ALIs), providing a score representing overall physiological dysregulation. Such ALIs have been shown to predict disease and mortality risk in western lowland gorillas. In these prior analyses, we were unable to include lipid markers, a potential limitation as they are key biomarkers in human models. Recently, we were able to assay serum cholesterol and triglycerides and add them to our previous ALI. We then re-examined associations with health outcomes using binomial generalized linear models. We constructed ALIs using 2 pooling strategies and 2 methods. By itself, a 1-unit increase in allostatic load was associated with higher odds of all-cause morbidity and mortality, but results were mixed for cardiac disease. However, the best fit models for all-cause morbidity and cardiac disease included only age and sex. Allostatic load was retained alongside age in the best fit models for mortality, with a 1-unit increase associated with 23% to 45% higher odds of death. Compared with previous results, ALIs containing cholesterol and triglycerides better predict disease risk in zoo-housed western lowland gorillas, as evidenced by larger effect sizes for some models and better goodness of fit for all ALIs. Based on these results, we address methodology for future allostatic load research on wildlife.
