Simian homologues of human herpesviruses and implications for novel viral introduction to free‐living mountain gorillas
The endangered mountain gorilla ( Gorilla beringei beringei ) in Rwanda, Uganda, and the Democratic Republic of Congo is frequently in contact with humans through tourism, research activities, and illegal entry of people into protected gorilla habitat. Herpesviruses, which are ubiquitous in primates, have the potential to be shared in any setting where humans and gorillas share habitat. Based on serological findings and clinical observations of o…

A partnership to build scientific capacity of Rwanda's future conservationists
The future of primates depends on conservationists in primate range countries having the education and opportunities needed to facilitate conservation efforts. However, most primates are found in countries where conservation is underfunded. Rwanda is home to 14 primate species, with three being listed as endangered on the International Union for Conservation of Nature (IUCN) Red List. Their remaining native habitats are scarce, highly fragmented,…
Coronaviruses Detected in Bats in Close Contact with Humans in Rwanda
Human Respiratory Syncytial Virus Detected in Mountain Gorilla Respiratory Outbreaks
Respiratory illness (RI) accounts for a large proportion of mortalities in mountain gorillas ( Gorilla beringei beringei ), and fatal outbreaks, including disease caused by human metapneumovirus (HMPV) infections, have heightened concern about the risk of human pathogen transmission to this endangered species, which is not only critically important to the biodiversity of its ecosystem but also to the economies of the surrounding human communities…
Faster growth corresponds with shallower linear hypoplastic defects in great ape canines
Quantifying linear enamel hypoplasia in Virunga Mountain gorillas and other great apes
OBJECTIVE: Linear enamel hypoplasia (LEH) is a condition marked by localized reductions in enamel thickness, resulting from growth disruptions during dental development. We use quantitative criteria to characterize the depth of LEH defects and "normal" perikymata in great apes. We test the hypothesis that mountain gorillas have shallow defects compared to other taxa, which may have led to their underestimation in previous studies. MATERIALS AND M…
Phylogenetic and environmental effects on limb bone structure in gorillas
OBJECTIVES: The effects of phylogeny and locomotor behavior on long bone structural proportions are assessed through comparisons between adult and ontogenetic samples of extant gorillas. MATERIALS AND METHODS: A total of 281 wild-collected individuals were included in the study, divided into four groups that vary taxonomically and ecologically: western lowland gorillas (G. g. gorilla), lowland and highland grauer gorillas (G. b. graueri), and Vir…
Incisor tooth wear and age determination in mountain gorillas from Volcanoes National Park, Rwanda
OBJECTIVES: Ecological factors, but also tooth-to-tooth contact over time, have a dramatic effect on tooth wear in primates. The aim of this study is to test whether incisor tooth wear changes predictably with age and can thus be used as an age estimation method in a wild population of mountain gorillas (Gorilla beringei beringei) from Volcanoes National Park, Rwanda. MATERIALS AND METHODS: ) as a proxy for incisal macrowear. Linear and quadratic…
Body mass estimation in hominoids
Toughness of the Virunga mountain gorilla ( Gorilla beringei beringei ) diet across an altitudinal gradient
The robust masticatory system of mountain gorillas is thought to have evolved for the comminution of tough vegetation, yet, compared to other primates, the toughness of the mountain gorilla diet is unremarkable. This may be a result of low plant toughness in the mountain gorilla environment or of mountain gorillas feeding selectively on low-toughness foods. The goal of this paper is to determine how the toughness of the mountain gorilla diet vari…
Screening wild and semi‐free ranging great apes for putative sexually transmitted diseases
First published: 26 June 2015 DOI: 10.1002/ajp.22442 In Rushmore et al., there was an error that affected the phylogenetic analysis presented in Figure 2. Below is a corrected version of Figure 2, which includes sequences from fecal and urine samples obtained from chimpanzees in our study and other related parasites (with Genbank accession numbers). Full-length (250 ±1 nt) Illumina reads from fecal samples were paired by name and merged using Gen…
Morbidity and mortality in infant mountain gorillas ( Gorilla beringei beringei )
Long-term studies of morbidity and mortality in free-ranging primates are scarce, but may have important implications for the conservation of extant populations. Infants comprise a particularly important age group, as variation in survival rates may have a strong influence on population dynamics. Since 1968, the Mountain Gorilla Veterinary Project (MGVP, Inc.) and government partners have conducted a comprehensive health monitoring and disease in…
A radiographic study of permanent molar development in wild Virunga mountain gorillas of known chronological age from R wanda
OBJECTIVES: While dental development is important to life history investigations, data from wild known-aged great apes are scarce. We report on the first radiographic examination of dental development in wild Virunga mountain gorillas, using known-age skeletal samples recovered in Rwanda. MATERIALS AND METHODS: In 43 individuals (0.0-14.94 years), we collected radiographs of mandibular molars, and where possible, cone beam CT scans. Molar crown a…
Body growth and life history in wild mountain gorillas ( Gorilla beringei beringei ) from Volcanoes National Park, Rwanda
OBJECTIVES: Great apes show considerable diversity in socioecology and life history, but knowledge of their physical growth in natural settings is scarce. We characterized linear body size growth in wild mountain gorillas from Volcanoes National Park, Rwanda, a population distinguished by its extreme folivory and accelerated life histories. METHODS: In 131 individuals (0.09-35.26 years), we used non-invasive parallel laser photogrammetry to measu…
Detection of viruses using discarded plants from wild mountain gorillas and golden monkeys
Infectious diseases pose one of the most significant threats to the survival of great apes in the wild. The critically endangered mountain gorilla (Gorilla beringei beringei) is at high risk for contracting human pathogens because approximately 60% of the population is habituated to humans to support a thriving ecotourism program. Disease surveillance for human and non-human primate pathogens is important for population health and management of p…
Age‐related changes in molar topography and shearing crest length in a wild population of mountain Gorillas from Volcanoes National Park, Rwanda
OBJECTIVES: Great ape teeth must remain functional over long lifespans. The molars of the most folivorous apes, the mountain gorillas, must maintain shearing function for 40+ years while the animals consume large quantities of mechanically challenging foods. While other folivorous primates experience dental senescence, which compromises their occlusal surfaces and affects their reproductive success as they age, it is unknown whether dental senesc…
Tooth wear and feeding ecology in mountain gorillas from Volcanoes National Park, Rwanda
OBJECTIVES: Ecological factors have a dramatic effect on tooth wear in primates, although it remains unclear how individual age contributes to functional crown morphology. The aim of this study is to determine how age and individual diet are related to tooth wear in wild mountain gorillas (Gorilla beringei beringei) from Volcanoes National Park, Rwanda. MATERIAL AND METHODS: We calculated the percent of dentine exposure (PDE) for all permanent mo…
Screening wild and semi‐free ranging great apes for putative sexually transmitted diseases
Sexually transmitted diseases (STDs) can persist endemically, are known to cause sterility and infant mortality in humans, and could have similar impacts in wildlife populations. African apes (i.e., chimpanzees, bonobos, and to a lesser extent gorillas) show multi-male mating behavior that could offer opportunities for STD transmission, yet little is known about the prevalence and impact of STDs in this endangered primate group. We used serology …
Brain organization of gorillas reflects species differences in ecology
Gorillas include separate eastern ( Gorilla beringei ) and western ( Gorilla gorilla ) African species that diverged from each other approximately 2 million years ago. Although anatomical, genetic, behavioral, and socioecological differences have been noted among gorilla populations, little is known about variation in their brain structure. This study examines neuroanatomical variation between gorilla species using structural neuroimaging. Postmo…
Early Brain Growth Cessation in Wild Virunga Mountain Gorillas ( Gorilla beringei beringei )
Understanding the life history correlates of ontogenetic differences in hominoid brain growth requires information from multiple species. At present, however, data on how brain size changes over the course of development are only available from chimpanzees and modern humans. In this study, we examined brain growth in wild Virunga mountain gorillas using data derived from necropsy reports ( N = 34) and endocranial volume (EV) measurements ( N = 86…
