This selection of 29 papers grew out of a symposium entitled "Setting the longer term schedule for Neotropical Primates. " The symposium was once held on the division of Zoo­ logical examine, nationwide Zoological Park, Washington D. C. , on February 26-27, 1994, and was once backed via the Wenner-Gren beginning for Anthropological learn, Smith­ sonian establishment, and pals of the nationwide Zoo. We positioned the symposium including goals: to honor Warren G. Kinzey for his contributions to the growing to be box of platyrrhine experiences and to supply researchers who paintings within the Neotropics with the oppor­ tunity to debate contemporary advancements, to spot parts of study that require extra learn, and particularly to aid consultant the subsequent iteration of researchers. The symposium supplied the chance to acknowledge Warren as a mentor and col­ laborator to the contribution of the research of platyrrhines. Contributions to the ebook have been increased for you to offer a extra finished view of platyrrhine evolution and ecology, to stress the interdisciplinary nature of lots of those stories, and to excessive­ mild the significant position that New global monkeys play in advancing primatology. If this vol­ ume have been to require significant revisions after only one extra decade of analysis, that will be a becoming testomony to Warren's enthusiasm and his force to repeatedly replace the sector with new principles and strategies. Tributes to Warren and an inventory of his guides were released in different places (Norconk, 1994, 1996; Rosenberger 1994, 1995).

P. personatus in the region of the Rio Doce, C. p. barbarabrownae and the new C. personatus referred to by Kobayashi and Langguth (1994) are relict, scattered, and scarce populations surviving in today's remnants of the Atlantic forest in the interior and northern coastal regions of Bahia and Sergipe. , 1993). Cebus apeUa evidently colonized the Atlantic forest as a full-blown species, and shows a degree of subspecific differentiation not present in the Amazon, where only one subspecies is currently recognized, although Torres (1988) indicated the likelihood of two.

Penicillata, and therefore more susceptible to isolation than would be the case today. Given that Leontopithecus, Brachyteles, and, to a lesser extent, Callithrix exhibit a higher degree of habitat specialization, climatic fluctuations resulting in dynamic contraction and expansion cycles, affecting more seriously the interior of Brazil where cerrado is found today, would effectively result in a higher degree of divergence of the ancestral stocks of these three genera than would be the case for the more adaptable genera, Cebus, Alouatta and Callicebus.

B. Rylands et al. (1984) this would have occurred in the mid-Miocene, some 14-15 million years ago. If Brachyteles arose as a result of the isolation of an ancestral form in the Atlantic forest, this would argue for the break occurring at one of these two times. The separation of the atelines pre-dates the radiation of the extant callitrichins which is believed to have occurred in the late Miocene, early Pliocene, some five million years ago according to Rosenberger (1984), although later Rosenberger (I 992a) indicates that the radiation began much earlier, 16 million years ago, with Saguinus branching off about 10 million years ago .
