“…Several other studies, however, have demonstrated significant physical differences between free‐ranging and captive populations including that free‐ranging animals grow for longer periods of time (Altmann et al,1981; Cheverud et al,1992), mature later (Altmann et al,1981; Altmann and Alberts,2005) and have delayed dental eruption (Phillips‐Conroy and Jolly,1988; Zihlman et al,2004). Several behavioral aspects of feeding can differ in captivity as well, including manual manipulation of food and posture during feeding (Kerridge,1997), ability to forage and locate food items (Snowdon,1994; Britt and Iambana,2003), food choice (Fernandes,1996; Jildmalm et al,2008), and the social context of feeding (Brent et al,1993; Carlstead,1996; Yamamoto and Lopes,2004). Collectively, these observations demonstrate the potential for differential growth and behavioral development to impact feeding behaviors in captive versus wild primates.…”
