Current Collaborations

Bradley, Brenda (Ph.D.)
Anthropology, Yale University, USA
Goal: evolution of coat color in owl monkeys species

Coleman, Mark N. (Ph.D.)
Midwestern University, USA
Goal: to compare the orbit and skull size in cathemeral owl monkeys of the Argentinean Chaco with those of fully nocturnal owl monkey species

de la Iglesia, Horacio (Ph.D.)
Biology, University of Washington, USA
Goal: to study the genetics, physiology and ecology of activity patterns and sleep in owl monkeys.

Anthony Di Fiore, Ph.D.
Anthropology, University of Texas, USA
Tony and I met while we were both graduate students at UC Davis. For many years, we dreamed about joining efforts to do research and training in anthropology and primatology in Latin America. In 2002, we initiated a long-term research program to understand the socioecology of monogamy, pairbonds and parental care in New World primates. Now, in the Comparative Socioecology of Monogamous Primates Project, we study together titis, sakis and owl monkeys in Tony’ primary field site in the Amazon rainforests of Yasuní National Park, Ecuador and in the Owl Monkey Project’s site in the Argentinean Chaco.

Emery Thompson, Melissa (Ph.D.)
Anthropology, University of New Mexico, USA
Goal: analyses of C-peptide to understand the energetics of biparental care in owl monkeys

Erkert, Hans (Ph.D.)
Emeritus, Biology, University of Tubingen, Germany
Goal: analyses of activity patterns in cathemeral owl monkeys using automatic recording devices (i.e. accelerometer collars).

Evans, Sian (Ph.D.)
Dumond Conservancy for Tropical Forests and Primates, USA

Golombek, Diego (Ph.D.)
Depto. Ciencia y Tecnologia, Universidad Nacional del Quilmes, Argentina
Goal: to study the clock genes in owl monkeys

Maren Huck, Ph.D.
Post-Doctorate Fellow, Owl Monkey Project
In collaboration with Maren we are currently conducting a study to learn about the Predators of the Owl Monkeys in the Guaycolec Ranch. Using an extensive camera trap system, she is collecting data and pictures of the neighbors of the monkeys. She is also collaborating in the analyses and organization of long-term demographic and behavioral data leading to some fascinating results on growth and development, termination of pair-bonds and serial monogamy.

Mundy, Nick (Ph.D.)
Biology, Oxford University, England
Goal: Do cathemeral owl monkeys have dichromatic colour vision?

Power, Michael (Ph.D.)
Conservation Biology Institute, Nat Zoo, USA
Goal: Energetics of biparental care

Rago, María Virginia (Doctor in Veterinary Sciences)
Wildlife Conservation Society, Argentina
Goal: to conduct a health evaluation of the owl monkey population in Formosa, Argentina

Rosenberg, Alfred (Ph.D.)
Brooklyn College, CUNY, USA
Goal: to carry out dental wear studies and biometric analyses of the Aotus azarai craniodental and postcranial material aimed at improving our understanding of Aotus diet and feeding behaviour.

Rudran, Rudy (Ph.D.)
Emeritus, Smithsonian Institution, USA
Goal: analyses of the long-term (1970-1999) demographic data on red-howlers (Alouatta seniculus) of Hato Masaguaral, Venezuela.

Schurr, Theodore G. (Ph.D.)
Anthropology, University of Pennsylvania, USA
Goal: a comprehensive examination of Aotus azarai genetics at the population, group and individual level

Stumpf, Rebecca M. (Ph.D.)
Anthropology, University of Illinois-Urbana-Champaign, USA
Goal: a study of the microbial fauna in the vaginal and rectal tract of wild owl monkeys

Valeggia, Claudia R. (Ph.D.)
Anthropology, University of Pennsylvania, USA
My colleague and spouse, Claudia and I have run parallel research paths since we met at the University of Buenos Aires where we studied together memory and learning in crabs.  Since then we have always collaborated on numerous projects. Together, we founded the Fundación ECO in 1999, with the aim to promote education in Argentina. At her field site in Formosa, Claudia conducts Reproductive Biology research with the Toba and Wichí of the Argentine Chaco. Her knowledge about hormones, behavior, and life-history and her Reproductive Ecology Laboratory at Penn have been instrumental in the success of my own examination of the hormonal bases of monogamy and biparental care in non-human primates.
