ArticleChanges in Ranging and Agonistic Behavior of Vervet Monkeys (Cercopithecus aethiops) after Predator-Induced Group FusionJaffe, Karin EnstamSocio-ecological theory predicts that group fusion in female-philopatric primate species will be rare because females experience increased costs by associating with non-relatives. Indeed, fusion has been reported only 14 times in only 4 female-philopa . . .
ArticleDemography and Life Histories of Sympatric Patas Monkeys, Erythrocebus patas, and Vervets, Cercopithecus aethiops, in Laikipia, KenyaYoung, Truman P.Mortality patterns are thought to be strong selective forces on life history traits, with high adult mortality and low immature mortality favoring early and rapid reproduction. Patas monkeys (Erythrocebus patas) have the highest potential rates of pop . . .
ArticleJaffe, Karin EnstamHere we describe changes in ranging behavior and other activities of vervet monkeys (Cercopithecus aethiops) after a wildfire eliminated grass cover in a large area near the study group's home range. Soon after the fire, the vervets ranged farther awa . . .
ArticleComparison of Responses to Alarm Calls by Patas (Erythrocebus patas) and Vervet (Cercopithecus aethiops) Monkeys in Relation to Habitat StructureJaffe, Karin EnstamWe studied responses to alarm calls of sympatric patas (Erythrocebus patas) and vervet (Cercopithecus aethiops) monkeys in relation to habitat structure, with the intention of understanding the relationship between the environment and predator avoidan . . .
