Preliminary Report: Antipredator Behaviors of Mandrills
نویسندگان
چکیده
Predation has likely been a major selective force shaping the evolution of primates. As a result of this current and past force, primates display a variety of antipredator behaviors. Because natural encounters with predators are infrequently observed, we do not have knowledge about the antipredator behaviors of many primate species. The aim of this study was to investigate how one such primate, mandrills (Mandrillus sphinx), responds to its predators. We presented visual models of leopards and crowned hawk-eagles to semi-free ranging mandrills and recorded their behavioral and vocal responses. The results indicated that mandrills tended to respond appropriately to different predator stimuli by running into trees for leopard presentations and seeking cover for eagle presentations; the mandrills emitted alarm calls at higher rates and for longer amounts of time in the leopard presentations compared to the eagle presentations.

Although secondary sexual adornments are widespread in male primates, few studies have examined female choice for these characters. The mandrill (Mandrillus sphinx) presents an extreme example of sexual dimorphism, with males exhibiting an array of striking adornments. The most dominant adult male in a group exhibits the brightest and most extensive red coloration, while other males are less br...

متن کاملMandrills use olfaction to socially avoid parasitized conspecifics
The evolutionary transition from a solitary to a social lifestyle entails an elevated parasite cost because the social proximity associated with group living favors parasite transmission. Despite this cost, sociality is widespread in a large range of taxonomic groups. In this context, hosts would be expected to have evolved behavioral mechanisms to reduce the risk of parasite infection. Few emp...
متن کاملMother Cottonmouths (Agkistrodon piscivorus) Alter Their Antipredator Behavior in the Presence of Neonates
Neonate-directed care is rare in non-avian reptiles, but female pitvipers attend their young for a period of time after birth. One of the primary functions of parental care is the protection of offspring from predators, and parents of diverse taxa are able to modulate their antipredator behavior in the presence of offspring. To test the hypothesis that the antipredator behavior of post-parturie...
متن کاملGenetic Basis of Activity Metabolism. I. Inheritance of Speed, Stamina, and Antipredator Displays in the Garter Snake Thamnophis Sirtalis.
Recent conceptual advances in physiological ecology emphasize the potential selective importance of whole-animal performance. Empirical studies of locomotor performance in reptiles have revealed surprising amounts of individual variation in speed and stamina. The present study is the first in a series examining the genetic basis of variation in locomotor performance, activity metabolism, and as...
