Ecological correlates of interindividual distance in the St. Kitts veret (Cercopithecus aethiops sabaeus)

  • Lynn A. Fairbanks

Field data were collected on a free ranging population of vervet monkeys (Cercopithecus aethiops sabaeus) on St. Kitts to test four hypotheses relating cover, risk of predation, and food density to interindividual distance. The results indicated that when food was not a factor, interindividual distance was positively related to the amount of cover in the immediate environment, and therefore to risk of predation. When cover was held constant, distance was inversely related to food density. When the minimum distance for optimal foraging was greater than that required for safety, a compromise distance intermediate between the two predicted values was observed. Cover and food density also predicted the inverse relationship found between age-sex class and interindividual distance. Implications of the above in relation to interindividual competition are discussed.
