Fruit color and size are significant determinants of food choice in mammals and birds, but hardness, an important physical property of fruit and seeds, has generally been overlooked as a determinant of food choice in studies of mammalian foraging behavior. Two methods were used to determine fruit hardness during a field study of two sympatric primates, the(More)
Mechanico-functional features of molar form were studied in Callithrix, Alouatta, Pithecia and Cebus. Molars of Callithrix and Alouatta are adapted to loading foods under relatively high occlusal pressure; those of Pithecia and Cebus, under relatively low occlusal pressure. General functional considerations suggest that these taxa are adapted to(More)

Since Mivart (1865), Cacajao, Chiropotes, and Pithecia have been grouped into a single taxon, which he called the subfamily Pitheciinae but which I, following Rosenberger (this issue), refer to as the living members of the tribe Pitheciini. While few today doubt the association of these three living genera, not all would place them together with Aotus and(More)
The marmosets and tamarins fill a unique ecological role among the anthropoid primates, one that has not been fully recognized. Many misconceptions--that they are primitive, monogamous, territorial, and squirrellike--pervade the literature. These misconceptions are largely the result of misinterpreting laboratory studies which have not been confirmed with(More)
We suggest four ways in which human gross anatomy instructors can reinforce respect and compassion in students. First, encourage respectful language in the laboratory. The term "donor" should be used instead of "cadaver" or "corpse" in referring to the donated body because this promotes appreciation for the students' first "patient." Second, provide the(More)
Observations are reported on the response of a free-ranging group of Callicebus torquatus to recordings of loud intergroup calls. When the recording consisted of the call of a solo adult male, the group fled from the recording. When the recording consisted of the adult male and female duetting together, the group remained in place and called back to the(More)
