Increased folivory in brown spider monkeys Ateles hybridus living in a fragmented forest in Colombia

Abstract: Brown spider monkeys Ateles hybridus are one of the most threatened primates in the Neotropics. Most of the remaining populations of this species already live either in forest fragments or in areas that face imminent anthropogenic disturbance. Understanding how these animals cope with the challenge of living in small fragments, while at the same time being a large, frugivorous mammal is crucial to design effective conservation and management strategies. We studied the diet of wild A. hybridus and measured fore… Show more

“…Increasing low energy and/or more difficult to digest food in this mainly frugivorous species as a response to habitat degradation is a strategy in line with a previous comparison with populations living in more pristine habitats (Donati et al, 2011). It also matches with previous studies on other frugivorous or frugivorous‐folivorous primates in fragmented habitats (Chaves et al, 2012; de Luna et al, 2017; Dunn et al, 2010; Felton et al, 2009; Irwin, 2008; Riley, 2007; Tutin, 1999; but see Bicca‐Marques, 2003; Cristóbal‐Azkarate & Arroyo‐Rodríguez, 2007). In translocated groups of Alouatta palliata at Agaltepec Island, Mexico, an increased consumption of nonfruit parts of plants such as leaves was also reported (Rodríguez‐Luna et al, 2003).…”

“…However, during the immediate postrelease years (2001–2003) we found the lowest values of dietary breadth for both number of food species and dietary diversity (Figure 3). This observation is not in line with the predictions of optimal foraging theory, that the animals would have increased their dietary breadth when consuming lower quality food such leaves (Chaves et al, 2012; Cristóbal‐Azkarate & Arroyo‐Rodríguez, 2007; Dunn et al, 2010; MacArthur & Pianka, 1966; but see de Luna et al, 2017). Although increasing dietary diversity may balance toxin or digestibility inhibitor overload (Freeland & Janzen, 1974; Glander, 1981), the groups may have had difficulties to locate food resources in the initial period after the release.…”

“…Previous studies demonstrate that spider monkeys in fragmented landscapes can decrease their dependence on ripe fruits by eating more leaves (Chaves et al, 2012;de Luna et al, 2017).…”
