Alarm calls can code for different classes of predators or different types of predatory threat. Acoustic information can also encode the urgency of threat through variations in acoustic features within specific alarm call types. Squirrel monkeys (Saimiri sciureus) produce an alarm call, known as the alarm peep, in highly threatening situations. Infant squirrel monkeys appear to have an innate p...

Compared to other mammalian orders, Primates use an extraordinary diversity of locomotor behaviors, which are made possible by a complementary diversity of musculoskeletal adaptations. Primate locomotor repertoires include various kinds of suspension, bipedalism, leaping, and quadrupedalism using multiple pronograde and orthograde postures and employing numerous gaits such as walking, trotting,...

Stable isotope biogeochemistry has been used to investigate foraging ecology in non-human primates for nearly 30 years. Whereas early studies focused on diet, more recently, isotopic analysis has been used to address a diversity of ecological questions ranging from niche partitioning to nutritional status to variability in life history traits. With this increasing array of applications, stable ...

While this volume has been structured around three key themes, reflecting key research interests of Colin’s over the years, what has clearly emerged is the enormous influence Colin has had, at a range of levels and degrees of pervasiveness, on the thinking of many people. Our title, Taxonomic Tapestries, evokes Colin’s legacy in a number of ways with Kelley and Sussman’s (2007) paper on academi...

Previous studies have noted substantial human-macaque interactions involving physical contact in Bali, Indonesia; Gibraltar; and Mt. Emei, China [Fuentes, American Journal of Primatology 68:880-896, 2006; Zhao, Tibetan macaques, visitors, and local people at Mt. Emei: problems and countermeasures. In: Paterson and Wallis, editor. Commensalism and conflict: the human-primate interface. Norman, O...

One of the goals of physical anthropology and primatology is to understand how primate social systems influence the evolution of sexually selected traits. Howler monkeys provide a good model for studying sexual selection due to differences in social systems between related species. Here, we examine data from the sister howler monkey species Alouatta palliata and A. pigra inhabiting southeastern...

RESEARCH ON the behavior and ecology of New World primates (infraorder Platyrrhini) began in the 1930s with C. R. Carpenter’s pioneering work on mantled howler monkeys (Alouatta paliatta) and Geoffroy’s spider monkeys (Ateles geoffroyi) in Panama (Strier 1994a, for a brief review). It was not until the late 1970s and 1980s, however, that signifi cant work on the ecology and behavior of wild pop...

In "The Snark is a Boojum", Beach [Beach, F.A., 1950. The snark was a boojum. American Psychologist. 5, 115-124] famously asserted that animal psychology embraced too few species and too few problems to deserve the name comparative. Later in the 20th century, others [e.g. Kamil, A.C., 1988. A synthetic approach to the study of animal intelligence. In: Leger, D.W. (Ed.), Comparative Perspectives...

and Conservation, Developments in Primatology: Progress and Prospects 49, DOI 10.1007/978-1-4614-7666-5_15, © Springer Science+Business Media New York 2014 Abstract Understanding the strategies that primates use to survive in fragmented forest landscapes is vital for constructing informed management plans for specific regions and to enable researchers to start to make generalizations. In a 15-m...
