Infant socialization in Primates

This review considers evolutionary trends, functions, stages, and current issues in Primate socialization. The concept of social “set” is discussed in the context of the interactional nature of socialization, where the infant is regarded as a primary effector in its own socialization. Laboratory approaches and measurement techniques are reviewed briefly.     

Prolactin Synthesis in Primates

THERE is compelling physiological evidence that prolactin and growth hormone in primates are separate proteins, but no conclusive chemical evidence has been obtained in support of this¹. Indeed the close similarity in the primary structure of human pituitary growth hormone (HGH) and ovine pituitary lactogenic hormone² has reinforced the view that perhaps, in the human, lactation and growth are controlled by a single pituitary protein. Histological and immunofluorescence studies using antiserum to ovine prolactin (AOP)³ have shown, however, that there is a substance in primate pituitaries which is immunochemically related to ovine prolactin (OP) and distinguishable from growth hormone.     

Species Concept in Primates

The way we view the Species category in Primates, as in other animals, especially other vertebrates, has been going through a revolution over the past 20 years or so. Much is wrong with the idea that we can define species according to whether or not they are “reproductively isolated”: this concept, the so‐called Biological Species Concept, has never offered any guidelines in the case of allopatric populations; this has now been shown to be simply wrong. Although other ways of looking at species – the Evolutionary, Recognition, Cohesion and Genetic Species Concepts – have all provided particular insights, the only proposal to offer a repeatable, falsifiable definition of species is the Phylogenetic Species Concept. This has been criticised for increasing the number of species to be recognised, although it is not clear why this should be a problem: indeed, it tells us that the world is far richer in biodiversity than we had conceived.

灵长类动物的食物分享行为

食物分享是灵长类动物的一种重要社会交往行为,主要发生在成体-幼体间和成体-成体之间。本文从这两个方面对灵长类动物食物分享的行为表现、特点以及功能进行总结,着重比较了无亲缘关系的成年个体间食物分享的互惠解释和骚扰解释。通过对以上内容的综合分析,进一步提出了食物分享行为的未来研究方向以及对人类合作行为演化的启示。     

Self-injurious Behavior in Zoo Primates

Researchers have long known that social isolation of some primates, particularly in infancy, can lead to the development of abnormal behaviors including self-injurious behavior (SIB). However, SIB can also occur in non-isolate-reared primates and can be triggered by frustration or environmental events. The subjects of reports of SIB have mostly been laboratory primates, usually macaques. Researchers had not systematically studied whether SIB occurs in zoo primates, and if so to what extent. Here we report the results of a questionnaire-based survey of British and Irish zoos on the extent of SIB in zoo primates, and whether it was associated with any environmental or developmental events. Responses indicated that though SIB occurred across a range of primate species, its incidence was very low. Respondents identified a variety of environmental events as implicated in initiating SIB, and though the data set is too small to confirm them statistically, several trends were discernible. We conclude that SIB is not a major problem in zoo primates.     

Primates and Cameras

Field-based primate studies often make population inferences using count-based indices (e.g., individuals/plot) or distance sampling; the first does not account for the probability of detection and thus can be biased, while the second requires large sample sizes to obtain precise estimates, which is difficult for many primate studies. We discuss photographic sampling and occupancy modeling to correct for imperfect detection when estimating system states and dynamics at the landscape level, specifically in relation to primate ecology. We highlight the flexibility of the occupancy framework and its many applications to studying low-density primate populations or species that are difficult to detect. We discuss relevant sampling and estimation procedures with special attention to data collection via photographic sampling. To provide tangible meaning to terminology and clarify subtleties, we use illustrative examples. Photographic sampling can have many advantages over observer-based sampling, especially when studying rare or elusive species. Combining photographic sampling with an occupancy framework allows inference to larger scales than is common in primate studies, addresses uncertainty due to the observation process, and allows researchers to examine questions of how landscape-level anthropogenic changes affect primate distributions.     

Mate Choice in Non-Human Primates

Mate choice has been observed in many species of non-human primates.There are few definitive studies, however, due to the long lifespans, complex social behavior, and cognitive abilities of theseanimals. Here I review the current literature on mate choicein primates. Females typically prefer complex behavioral traitssuch as social status, familiarity, personality, and parentalcare abilities. This tendency to prefer behavioral traits isconsistent with the non-primate mammalian data. A female's abilityto express preferences, however, is often constrained by hersocial environment—in particular male mating tactics andfemalefemale competition. Males exhibit preferences for high-ranking females. In severalspecies, high-ranking females produce more offspring than low-rankingfemales. In addition, females may also influence male dominancerank and in doing so reduce male-male competition and increasemale mating success.     

Sex-Biased Parental Investment in Primates

Parental investment enhances an offspring's chances of survival concomitant with reducing the parent's ability to invest in other offspring. Three main models might explain the conditions under which parental investment is expected to be sex-biased, but accurately testing the models is difficult. At least 7 fundamental issues remain unresolved in the area of parental investment in primates. The central dilemma is trying to gauge how the process improves the survival and reproductive prospects of current progeny at the expense of the survival or fertility of the parent. No single model is likely to be applicable to all primates. Parental investment probably operates in a condition-dependent framework designed to maximize lifetime reproductive success, but whether sex-biased investment occurs in an adaptive fashion remains unresolved.

Disproportional Representation of Primates in the Ecological Literature

We address the question why papers dealing with the ecology of primates are so sparsely represented in the general ecological literature. A literature analyses based on entries in Web of Science and PrimateLit reveals that despite a large number of papers published on primates in general and on the ecology of primates, only a very small fraction of these papers is published in high-ranking international ecological journals. We discuss a number of potential reasons for the disproportion and highlight the problems associated with experimental research on wild primates and constraints on sample size as major issues.     

非人灵长类冲突后行为的研究进展

冲突后行为（post-conflict behavior）在非人灵长类中普遍存在。通过对旧大陆灵长类和类人猿的冲突后行为的观察,人们早期主要关注其和解行为,随着研究的不断深入,近些年来则对转向攻击行为、安慰行为和替代和解行为等其他冲突后行为也多有涉猎。目前主要应用匹配控制观察法来研究灵长类的冲突后行为,发现不同的物种往往有不同的冲突后行为模式,她们的统治风格、亲豫关系、等级地位远近及冲突起因等因素会对冲突后行为产生影响,进而发现不同的冲突后行为模式具有不同的功能,并且提出了社会认知、社会约束和关系价值假说。
