Dissertation Research: Feeding and Ranging by the White-Handed Gibbon (Hylobates Lar) in Northern Thailand

摘要P.I.Robert Sussman/Thad Bartlett SBR-9314804一夫一妻制在我们的灵长类亲属和哺乳动物中相对罕见，其决定因素尚不清楚。通常，一夫一妻制被认为是在某些生态限制受到冲击时产生的--在某些情况下，男性可能无法垄断一个以上的女性，最终，男性可能无法控制足够的资源基础，以养活不止一个女性及其依赖的后代。在东半球较大的物种中，尤其是长臂猿，人们普遍认为，一夫一妻制是对它们对零散的小资源的依赖的回应，这些资源想必无法支撑更大的社会群体。然而，关于长臂猿觅食行为与资源可获得性有关的信息很少，部分原因是大多数数据是在赤道雨林收集的，那里的资源季节性很小，植物多样性很高。这项研究将在一个更简单的栖息地进行，有明显的湿季和旱季，食物供应的总体变化将更加明显，监测食物资源的变化可能与长臂猿的活动范围和社会行为有关。它将允许对目前关于资源分配和社会结构之间相互关系的假设进行明确评估。这项研究将得到富布赖特奖的部分支持。*P\anthro\jfred\9314804.abs~Z_|~！D~~(Times新罗马符号&amp；Arial“h F例如e=Jonathan Friedlaender Jonathan Friedlaender

ABSTRACT P.I. Robert Sussman/Thad Bartlett SBR - 9314804 Monogamy is relatively rare among our primate relatives, as well as mammals generally, and its determinants have not been clearly established. Typically, monogamy is argued to result when certain ecological constraints impinge - that in certain circumstances, males may be unable to monopolize more than one female, and ultimately, that males may not be able to control a sufficient resource base to support more than a single female and her dependent offspring. In larger Old World species, particularly gibbons, the argument has generally been that monogamy is a response to their dependence on small scattered resources that are presumably unbable to support larger social groups. However, there is a paucity of information on gibbon foraging behavior in relation to resouce availability, partially because most of the data have been collected in equatorial rain forests where there is little seasonality of resources, and plant diversity is high. This study will take place in a simpler habitat, with distinct wet and dry seasons, where gross changes in food availability will be more apparent, and where monitoring the variation in food resources can be related to ranging and social behaviors of the gibbons. It will permit a clear evaluation of current hypotheses concerning the interrelationship between resource distribution and social structure. This study will be supported partially by a Fulbright award. *** P\anthro\jfried\9314804.abs ~ Z _ | ~ ! ! ! !
