Since 2001, the Eastern Taxonomic Gorilla has been considered a separate species (Gorilla beringei) with two subspecies: Grauer’s Gorilla Notes: (Gorilla beringei graueri) and the Mountain Gorilla (Gorilla beringei beringei) following Groves (2001).

Reviewer(s): Mittermeier, R.A. & Rylands, A.B. Contributor(s): Butynski, T.M. & Gray, M. Justification: Eastern Gorillas (Gorilla beringei) live in the mountainous forests of eastern Democratic Republic of Congo, northwest Rwanda and southwest Uganda. This region was the epicentre of Africa's "world war", to which Gorillas have also fallen victim. The Mountain Gorilla subspecies (Gorilla beringei beringei), has been listed as Critically Endangered since 1996. Although a drastic reduction of the Grauer’s Gorilla subspecies (Gorilla beringei graueri), has long been suspected, quantitative evidence of the decline has been lacking (Robbins and Williamson 2008). During the past 20 years, Grauer’s Gorillas have been severely affected by human activities, most notably poaching for bushmeat associated with artisanal mining camps and for commercial trade (Plumptre et al. -
Conflict and Cooperation in Wild Chimpanzees
ADVANCES IN THE STUDY OF BEHAVIOR VOL. 35 Conflict and Cooperation in Wild Chimpanzees MARTIN N. MULLER* and JOHN C. MITANIt *DEPARTMENT OF ANTHROPOLOGY BOSTON UNIVERSITY BOSTON, MASSACHUSETTS, 02215, USA tDEPARTMENT OF ANTHROPOLOGY UNIVERSITY OF MICHIGAN ANN ARBOR, MICHIGAN, 48109, USA 1. INTRODUCTION The twin themes of competition and cooperation have been the focus of many studies in animal behavior (Alcock, 2001; Dugatkin, 2004; Krebs and Davies, 1997). Competition receives prominent attention because it forms the basis for the unifying, organizing principle of biology. Darwin's (1859) theory of natural selection furnishes a powerful framework to understand the origin and maintenance of organic and behavioral diversity. Because the process of natural selection depends on reproductive competition, aggression, dominance, and competition for mates serve as important foci of ethological research. In contrast, cooperation in animals is less easily explained within a Darwinian framework. Why do animals cooperate and behave in ways that benefit others? Supplements to the theory of natural selection in the form of kin selection, reciprocal altruism, and mutualism provide mechanisms that transform the study of cooperative behavior in animals into a mode of inquiry compatible with our current understand- ing of the evolutionary process (Clutton-Brock, 2002; Hamilton, 1964; Trivers, 1971). If cooperation can be analyzed via natural selection operating on indivi- duals, a new way to conceptualize the process emerges. Instead of viewing cooperation as distinct from competition, it becomes productive to regard them together. Students of animal behavior have long recognized that an artificial dichotomy may exist insofar as animals frequently cooperate to compete with conspecifics. -

To prevent Humans tend to be biased toward emotional images, especially conflicts, they keep close track of others’ behaviors, emotions, and when the emotion is of a threatening nature. Bonobos have rich, social debts. For example, chimpanzees remember who groomed social emotional lives and are known for their soft and friendly char- whom for long periods of time (26). In the chimpanzee, but also in acter. In the present study, we investigated (i) whether bonobos, the rarely studied bonobo, grooming is a major social activity and similar to humans, have an attentional bias toward emotional scenes a means by which animals living in proximity may bond and re- ii compared with conspecifics showing a neutral expression, and ( ) inforce social structures. -

Death of a Trapped Chimpanzee: Survival and Conservation of Great Apes in Unprotected Agricultural Areas of Uganda

In western Uganda, some farmers guard against crop losses to wildlife by placing large steel leg-hold traps (‘mantraps’) near their agricultural fields. Chimpanzees (Pan troglodytes schweinfurthii) can step in these illegal devices, resulting in severe injury or death. Here, we report a case of trapping and subsequent death of a wild chimpanzee from the Bulindi community (Hoima District). The elderly female chimpanzee died 13 days after being injured by a mantrap. Her injury could have contributed to the cause of death by impacting her balance in low trees above a stream; her body was subsequently found in the water. Behavioural observations prior to death and evidence from physical inspection of her injured hand suggest she may have otherwise recovered from her -

Chimpanzee Referents and the Emergence of Human Hunting Travis Rayne Pickering*,1,2 and Manuel Domínguez-Rodrigo3
The Open Anthropology Journal, 2010, 3, 107-113 107 Open Access Chimpanzee Referents and the Emergence of Human Hunting Travis Rayne Pickering*,1,2 and Manuel Domínguez-Rodrigo3 1Department of Anthropology, University of Wisconsin-Madison, 1180 Observatory Drive, 5240 Social Building, Madison, Wisconsin, 53706, USA; 2Institute for Human Evolution, University of the Witwatersrand, Private Bag 3, WITS 2050, Johannesburg, South Africa; 3Department of Prehistory, Complutense University, 28040, Madrid, Spain Abstract: The use of referent taxa, and especially chimpanzee referents, in modeling human evolution has been harshly criticized. No doubt, chimpanzee data are often misused in models of early hominid behavior. But, those misuses are ex- amples of careless, formal analogizing. In contrast, it is equally possible to create non-trivial chimpanzee analogies. These analogies can, in turn, be linked together to construct credible models of human evolution, from which emanate hypothe- ses that are testable using paleoanthropological data. Unique among potential referents, chimpanzees are very closely re- lated to early hominids and some populations reside in ecological contexts that are comparable to those of our African an- cestors. It is these two variables that form the core of evolutionary behavioral ecology. We exploit chimpanzee and early hominid continuities and employ non-trivial analogies to provide a model of basal hominid hunting. The model is testable and the topic is worthy because hunting and meat-eating are argued by some to be the basis of human sociality.
