Ebola & Great Apes
Ebola & Great Apes Ebola is a major threat to the survival of African apes There are direct links between Ebola outbreaks in humans and the contact with infected bushmeat from gorillas and chimpanzees. In the latest outbreak in West Africa, Ebola claimed more than 11,000 lives, but the disease has also decimated great ape populations during previous outbreaks in Central Africa. What are the best strategies for approaching zoonotic diseases like Ebola to keep both humans and great apes safe? What is Ebola ? Ebola Virus Disease, formerly known as Ebola Haemorrhagic Fever, is a highly acute, severe, and lethal disease that can affect humans, chimpanzees, and gorillas. It was discovered in 1976 in the Democratic Republic of Congo and is a Filovirus, a kind of RNA virus that is 50-100 times smaller than bacteria. • The initial symptoms of Ebola can include a sudden fever, intense weakness, muscle pain and a sore throat, according to the World Health Organization (WHO). Subsequent stages include vomiting, diarrhoea and, in some cases, both internal and external bleeding. • Though it is believed to be carried in bat populations, the natural reservoir of Ebola is unknown. A reservoir is the long-term host of a disease, and these hosts often do not contract the disease or do not die from it. • The virus is transmitted to people from wild animals through the consumption and handling of wild meats, also known as bushmeat, and spreads in the human population via human-to-human transmission through contact with bodily fluids. • The average Ebola case fatality rate is around 50%, though case fatality rates have varied from 25% to 90%. -

It does not exceed the prescribed word limit for the Archaeology and Anthropology Degree Committee. II Western Gorilla Social Structure and Inter-Group Dynamics Robin Morrison The study of western gorilla social behaviour has primarily focused on family groups, with research on inter-group interactions usually limited to the interactions of a small number of habituated groups or those taking place in a single location. Key reasons for this are the high investment of time and money required to habituate and monitor many groups simultaneously, and the difficulties of making observations on inter-group social interaction in dense tropical rainforest. -

We generated estimates in line with each of three proposed de®nitions for the reserve Ð its current boundaries, a moderate extension, and a greater extension. Estimates were based on current nest survey methods, adjusted for habitat type variability. Measures of habitat type coverage derived from a GIS developed for the DSWR region. Our estimates support impressions that the current DSWR harbors few orangutans (Æ200) but the greater extension supports a substantially larger population (>2000). Findings are discussed with respect to distribution (habitat preference), behavior in the DSWR area (migration, local stresses, human tolerance), and habitat protection plans. # 2000 Elsevier Science Ltd.

Genetic Variation in Gorillas
American Journal of Primatology 64:161–172 (2004) RESEARCH ARTICLE Genetic Variation in Gorillas LINDA VIGILANT* and BRENDA J. BRADLEY Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany This review summarizes what is currently known concerning genetic variation in gorillas, on both inter- and intraspecific levels. Compared to the human species, gorillas, along with the other great apes, possess greater genetic varation as a consequence of a demographic history of rather constant population size. Data and hence conclusions from analysis of mitochondrial DNA (mtDNA), the usual means of describing intraspecific patterns of genetic diversity, are limited at this time. An important task for future studies is to determine the degree of confidence with which gorilla mtDNA can be analyzed, in view of the risk that one will inadvertently analyze artifactual rather than genuine sequences. The limited information available from sequences of nuclear genomic segments does not distinguish western from eastern gorillas, and, in comparison with results from the two chimpanzee species, suggests a relatively recent common ancestry for all gorillas. In the near future, the greatest insights are likely to come from studies aimed at genetic characterization of all individual members of social groups. Such studies, addressing topics such as behavior of individuals with kin and non-kin, and the actual success of male reproductive strategies, will provide a link between behavioral and genetic studies of gorillas. Am. J. Primatol. 64:161–172, 2004. r 2004 Wiley-Liss, Inc. Key words: phylogeography; mtDNA; noninvasive samples; numt; genotype INTRODUCTION Genetic Variation in Wild Animal Populations Studies of genetic variation within a wild animal taxon commonly address two topics: an estimation of the amount of variation present in both individuals and populations, and a description of how that variation is geographically distributed [Avise, 2000]. -
The Evolutionary History of Human and Chimpanzee Y-Chromosome Gene Loss
The Evolutionary History of Human and Chimpanzee Y-Chromosome Gene Loss George H. Perry,* à Raul Y. Tito,* and Brian C. Verrelli* *Center for Evolutionary Functional Genomics, The Biodesign Institute, Arizona State University, Tempe; School of Life Sciences, Arizona State University, Tempe; and àSchool of Human Evolution and Social Change, Arizona State University, Tempe Recent studies have suggested that gene gain and loss may contribute significantly to the divergence between humans and chimpanzees. Initial comparisons of the human and chimpanzee Y-chromosomes indicate that chimpanzees have a dis- proportionate loss of Y-chromosome genes, which may have implications for the adaptive evolution of sex-specific as well as reproductive traits, especially because one of the genes lost in chimpanzees is critically involved in spermatogenesis in humans. Here we have characterized Y-chromosome sequences in gorilla, bonobo, and several chimpanzee subspecies for 7 chimpanzee gene–disruptive mutations. Our analyses show that 6 of these gene-disruptive mutations predate chimpan- zee–bonobo divergence at ;1.8 MYA, which indicates significant Y-chromosome change in the chimpanzee lineage Downloaded from https://academic.oup.com/mbe/article/24/3/853/1246230 by guest on 23 September 2021 relatively early in the evolutionary divergence of humans and chimpanzees. Introduction The initial comparisons of human and chimpanzee Comparative analyses of single-nucleotide differences (Pan troglodytes) Y-chromosome sequences revealed that between human and chimpanzee genomes typically show although there are no lineage-specific gene-disruptive mu- estimates of approximately 1–2% divergence (Watanabe tations in the X-degenerate portion of the Y-chromosome et al. 2004; Chimpanzee Sequencing and Analysis Consor- fixed within humans, surprisingly, 4 genes, CYorf15B, tium 2005). -
