A study was undertaken of a unique sample of 63 wild vervet monkeys Cercopithecus aethiops from a single population in Uganda collected over 35 days in 1947. Twenty-five were immature (12 females and 13 males) and 38 were adults (16 females and 22 males). Body mass, external measurements, masticatory and other masses were recorded for each individual at the time of collection, and for a few spe...

The vervet monkeys had moved out of their sleeping trees to forage on the ground. While the adults fed, the juveniles played in a nearby bush. Macauley, the rambunctious son of a lowranking female, wrestled Carlyle, the daughter of the highestranking female, to the ground. Carlyle screamed, chased Macauley away, and then went to forage next to her mother. Apparently the fi ght had been noticed ...

Eleven vervet monkeys (Cercopithecus aethiops) were fed with an "O" protein diet. After the serum albumin level fell below 2.5 g/100 ml the animals and 4 controls, which received regular monkey chow, were orally infected with a monkey-adapted strain of Vibrio cholerae. The total bactericidal activity of the jejunal fluid decreased during feeding with "O" protein diet, but increased after challe...

Discussions in this group focused on a particular problem that arises in animal movement ecology: how to link data describing movement (i.e. sequential GPScoordinates collected on wild and free-ranging animals) with geographical and environmental context (i.e. properties of the internal and external environment within which the animals move). Our case study comprised a spatio-temporal data set ...

Habitat selection by a group of vervet monkeys (Cercopithecus aethiops) living on the savanna peninsula of St. Kitts was investigated by the intensive sampling of 12 transects. The vervets exhibited nonrandom use of habitats. Examination of 20 ecological variables in each of the habitat types revealed that the vervets preferentially used areas of secondary growth characterized by high density a...

BACKGROUND Understanding the evolutionary origins of a phenotype requires understanding the relationship between ontogenetic and phylogenetic processes. Human infants have been shown to undergo a process of perceptual narrowing during their first year of life, whereby their intersensory ability to match the faces and voices of another species declines as they get older. We investigated the evol...
