Although radio tracking has been used increasingly in primate field studies over the past 15 years, some primatologists have been reluctant to use it. Their social complexity rivals that of some primates, and, in some respects, resembles the behavior of humans. The genealogy has been compiled to formally document the historical record of this young field. The major focus of this research was to test a method that differs from those used in most previous personality studies, while investigating the personality traits of 52 captive lion-tailed macaques from four zoos. Total genetic variation and relatedness in captive L.
We also investigated the genetic differentiation between the populations and dispersal partner relatedness. The perception of humans constructing and being constructed by the world and the warning to be cognizant of our approaches to defining ourselves are central themes here. Our goals were 1 to follow up questions raised in the earlier survey, 2 to compare population densities, and 3 to locate potential sites for future long-term research. Sauther Control code 000041022340 Dimensions 24 cm Extent 376 p. Moreover, interspecific associations may influence the presence or absence of primate species.
The incubation period averaged 18. © 2015 Wiley Periodicals, Inc. Ethan Pride, Dina Felantsoa, Tahiry Randriamboavonjy, -- and Randriambelona -- 14. . Despite criticisms that the evidence in support of the hypothesis is distorted by misinterpretation of data and observer bias, the sexual selection hypothesis, bolstered in part by additional reports of infanticide in a variety of specks, has become entrenched as the primary explanatory hypothesis for primate infanticide.
. Although there were many brief descriptions of wild ringtailed lemurs, it was not until Jolly wrote her now classic book, Lemur Behavior, that we had our first detailed description of the natural history of these beautiful animals Fig. We conclude that although all of the primate fauna appear to be present, the current rate of deforestation at Antserananomby is unsustainable. We strongly agree that we need to critically re-evaluate the basic assumptions of all models of primate sociality, and to verify the explanatory power of alternative models. Given more recent data on primate-like marsupials, nocturnal prosimians, and early fossil primates, and the context in which these primates first appeared, this theory has been modified.
Our multidisciplinary studies illustrate the feasibility of collecting long-term data on careers of individual animals and of obtaining large samples on numerous animals, across numerous social groups, in relatively isolated breeding populations. Ring-tailed lemurs Lemur catta are seasonally breeding primates that live in multi-male, multi-female groups. However, this theory of early hominin behavior is still widely debated within the anthropological community and, as we will show, the evidence to support it remains controversial. Juvenile mortality in 3 intensively studied groups was 57% during the second year of the drought. We used published age-specific death rates for red colobus Procolobus rufomitratus tephrosceles in Gombe National Park, Tanzania, to construct model life tables under various mortality scenarios. The data will be of interest to anyone conducting meta-analysis studies of primate diets.
Dorn George Willias and Hantanirina Rasamimnaanaa 9. She continues her research on their troops in Berenty Reserve, working with many colleagues and students. Lehman, Journal of Mammalian Evolution, Vol. Because the patterns of variation seen in this sample are from a known breeding population, the data presented here provide an important reference for interpreting and understanding the fossil record. Edited by Alison Jolly, Robert W. Both species appear to be rare, but may also be under represented in surveys.
The distribution section contains four chapters, two of which provide short overviews of the main sites where detailed field studies. Crawford, Louis-Expert Andriafaneva, Kathryn Blumenfeld-Jones, Gary Calaba, Linda Clarke, Lisa Gray, Shinichiro Ichino, Alison Jolly, Naoki Koyama, Anne Mertl-Millhollen, Susan Ostpak, R. Data are presented supporting the idea that the normal pattern for most diurnal primates and for humans is to be social. The morals described, however, often reflect ancient beliefs and appear to be new ways of justifying old morality codes. In the socioecological model, food distribution and abundance have been argued to be the primary influences on the social behavior of primate species.
This volume includes up-to-date field research on the longest-studied and best known of lemur species. The book is organized into four sections: distribution, feeding and ranging, social behavior, and health and disease. Salivary pH for the Indianapolis Zoo sample 8. The E-mail message field is required. Beza Mahafaly consists of two noncontiguous forest parcels separated by 10 km that became a protected area Réserve Spéciale in 1986: an 80-ha gallery forest and a 520-ha xerophytic spiny forest. To help alleviate the energetic costs of autonomic responses, these organisms often thermoregulate through behavioral mechanisms.
Data have been collected from three main sources: 1 e-mail surveys, 2 library and Internet research, and 3 verbal communication through forums such as American Association of Physical Anthropology meetings. Among the captive lemurs, only one lemur a nearly 29 year old male has lost more than one tooth. . This hypothesis suggests that infant killing is a form of sexual competition whereby an infanticidal male gains a reproductive advantage by selectively killing the offspring of his male rivals. Social animals, including primates and humans, are not forced to live socially but do so because it benefits them in numerous ways. Although theories and associations of human aggressive hunters abound, they are rarely based on the two evidentiary approaches that shed light on early hominin ecology and behavior-living primate models and the fossil record. His numerous writings include the textbook Origins of Man 1966 , an instant classic in physical anthropology.
If no action is taken to conserve what is left and restore what has been lost, then the forests in this region and their inhabitants are likely to soon disappear. The insulating properties of the primate integument are influenced by many factors, including piloerection, which raises the hair and insulates the body by creating motionless air near the skin's surface. The papers review past research and add new dimensions of research related to nutrition, health, hormonal biology, plant ecology, behavioral ecology, and demography of Lemur catta. The mitochondrial evidence supports the morphologically and historically based hypothesis that the original founders came from Indonesia. The distribution reported in 1975 for five monkey species—Alouatta seniculus, Cebus olivaceus, Pithecia pithecia, Chiropotes satanas,and Saimiri sciureus—was confirmed. Lineages of primatologists have been graphically displayed using Microsoft Visio. We present evidence that ring-tailed lemurs use these postures as behavioral thermoregulation strategies, and that different environmental variables are associated with the use of each posture.
