Influence of Ecological and Social Factors on Body Mass of Wild Chimpanzees (2005, background): “Significant differences in body mass at different population densities have been noted in several nonprimate species (LeBlanc et al., 2001; Pettorelli et al., 2002), and Bulger and Hamilton (1987) provide some evidence that masses of female chacma baboons increased during a time of declining troop…”
Growth rates in a wild primate population: ecological influences and maternal effects (2005, background): “Large differences in growth and maturation have often been associated with major, persistent differences in food availability, both for cercopithecine primates and for other mammals (e.g., primates: Mori 1979; Sugiyama and Ohsawa 1982; Strum 1991; Bercovitch and Strum 1993; also reviewed in Fa and S”
How does environmental variation influence body mass, body size, and body condition? Roe deer as a case study (2006, background): “2000), bighorn sheep (Leblanc et al. 2001), and Soay sheep (Clutton-Brock et al.”
Empirical Evidence of Density- Dependence in Populations of Large Herbivores (2009, background): “However, males maymodulate the costs of secondary sexual traits by adjusting the energy allocation to reproduction according to the level of density (bighorn sheep: Festa‐Bianchet et al. (2003); Leblanc et al. (2001); red deer: Yoccoz et al. (2002) fallow deer (Dama dama): McElligott et al. (2003)).”
Relative allocation to horn and body growth in bighorn rams varies with resource availability (2004, unknown): “We had previously shown that population density had a negative effect on body mass and total horn length of bighorn rams ( Jorgenson et al., 1998; Leblanc et al., 2001).”
Sexual selection and social rank in bighorn rams (2006, background): “Moreover, within a cohort, small individuals are likely to remain small as they age, because bighorn rams do not appear to be able to compensate for slow early growth (LeBlanc et al. 2001).”
Potential causes and life-history consequences of sexual size dimorphism in mammals (2005, background): “Clutton-Brock et al., 1982, 1987; Owen-Smith, 1993; Festa-Bianchet et al., 1996; LeBlanc et al., 2001; McElligott et al., 2001), have allowed a number of the hypotheses and predictions on the evolution and effects of SSD to be tested rigorously in individuals that have been studied throughout thei”
