Vocal, gestural and locomotor responses of wild chimpanzees to familiar and unfamiliar intruders: A playback study (2009, background): “If violence erupts, victims can sustain severe injuries within minutes, although aggressors sometimes also get hurt (Manson & Wrangham 1991; Boesch & Boesch-Achermann 2000; Williams et al. 2004).”
Foraging strategies as a function of season and rank among wild female chimpanzees (Pan troglodytes) (2006, background): “Males are highly gregarious and range widely in order to defend a community range (reviewed in Wrangham 2000; Williams et al. 2004).”
Group territoriality and the benefits of sociality in the African lion, Panthera leo (2009, background): “Male chimpanzees sometimes attack and kill sexually unreceptive adult females in neighbouring communities (Wilson & Wrangham 2003; Williams et al. 2004).”
Conflict and Cooperation in Wild Chimpanzees (2005, background): “Male chimpanzees defend their territories vigorously against neighbors (Boesch and Boesch‐Achermann, 2000; Goodall et al., 1979; Watts and Mitani, 2001; Williams et al., 2004).”
Core area quality is associated with variance in reproductive success among female chimpanzees at Kibale National Park (2007, unknown): “Chimpanzees live in a fissionefusion social system in which a group of bonded males aggressively defends a home range, including the food resources and females within it (Nishida 1968; Sugiyama 1968; Wrangham 1975; Williams et al. 2004).”
Correlates of territorial boundary patrol behaviour in wild chimpanzees (2005, background): “Patrols play an integral role in chimpanzee territorial behaviour, and three nonmutually exclusive functions for them have been proposed (Manson & Wrangham 1991; Wrangham 1999; Boesch & Boesch-Achermann 2000; Watts & Mitani 2001; Wilson & Wrangham 2003; Williams et al. 2004; Wilson et al. 2004).”
Chimpanzees (Pan troglodytes) modify grouping and vocal behaviour in response to location-specific risk (2007, unknown): “…means of identifying the extent of the range, and is widely used in other studies for this purpose (e.g., wolves, Mech, 1994; spotted hyenas (Crocuta crocuta), Boydston et al., 2003; chimpanzees, Chapman & Wrangham, 1993; Herbinger et al., 2001; Lehmann & Boesch, 2003; Williams et al., 2004).”
Immigration costs for female chimpanzees and male protection as an immigrant counterstrategy to intrasexual aggression (2008, unknown): “…numerous influences on dispersal (e.g. Nagy et al. 2007), a particularly important factor for chimpanzees is that male affiliation and cooperation are critical for defence of the community feeding range, the size of which affects the reproductive rates of resident females (Williams et al. 2004).”
Female Competition over Core Areas in Pan troglodytes schweinfurthii, Kibale National Park, Uganda (2008, unknown): “Increases in female density at Gombe negatively impact female reproductive rates (Williams et al. 2004).”
Influence of Ecological and Social Factors on Body Mass of Wild Chimpanzees (2005, background): “Their range size then started to contract in 1979 as the powerful Kalande community pushed its range north, and it was smallest (5.3 km2) in 1981 before starting to expand again to its current large size (Goodall, 1986; Williams et al., 2002, 2004).”
Fission–fusion social systems as a strategy for coping with ecological constraints: a primate case (2007, background): “The advantages gained by living in a larger community may be related to reproductive strategies and/ or to territory defence strategies (Lehmann and Boesch 2003; Williams et al. 2004).”
Ecological and social factors affect the occurrence and outcomes of intergroup encounters in chimpanzees (2012, unknown): “That chimpanzees gain benefits from acquiring more territory has been supported by results from three studies (Nishida 1979; Williams et al. 2004; Mitani et al. 2010).”
Severe Aggression Among Female Pan troglodytes schweinfurthii at Gombe National Park, Tanzania (2008, background): “Female reproductive rates are lower when density is higher (Williams et al. 2004).”
