项目摘要

The purpose of this project is to understand the proximate mechanisms, form, and evolutionary function(s) of social relationships between adult male and immature mountain gorillas (Gorilla beringei beringei). The project will address four primary questions: 1) are male and immature gorillas capable of distinguishing paternal kin from non-kin? 2) are such relationships hormonally mediated, specifically through testosterone and prolactin? 3) how do male-immature relationships change over time as immatures grow? and 4) is there evidence to support alternative hypotheses about the function of these relationships? Behavioral observations will be conducted on at least four groups of habituated gorillas living in Parc des Volcans, Rwanda, and monitored by the Karisoke Research Center. Adult males and immatures will be followed four days per week, and all relevant behaviors recorded. Hormonal data will be collected using non-invasive methods, specifically collection of urine samples from adult males and collection of fecal samples from males, mothers, and immatures. Hormones will be extracted from the samples in Rwanda before being shipped to the Lincoln Park Zoo in Chicago, Illinois for analysis. The role of fathers is variable across non-human primate species, but to date little research has been conducted on non-monogamous species and great apes. Mountain gorillas are an interesting study species because of their highly flexible social structure, which includes both multi and single-male groups, and therefore bears similarities to variability in human mating systems. This project will give us insight into the origins of paternal behavior in different mating systems and the implications it has for offspring, in both the short and long term. This award will provide support to enable a promising student to establish a strong independent research career.

本项目的目的是了解成年雄性和未成年山地大猩猩（Gorilla beringei beringei）之间社会关系的近似机制，形式和进化功能。该项目将解决四个主要问题：1）雄性和未成熟的大猩猩能够区分父系亲属和非亲属吗？2)这种关系是否通过睾丸激素和催乳素介导？3)随着不成熟的成长，男性与不成熟的关系是如何变化的？4）是否有证据支持关于这些关系的功能的替代假设？将对生活在卢旺达火山公园的至少四组习惯性大猩猩进行行为观察，并由Karisoke研究中心进行监测。成年雄性和未成年雄性将每周随访四天，并记录所有相关行为。将使用非侵入性方法采集激素数据，特别是采集成年男性的尿液样本和采集男性、母亲和未成熟动物的粪便样本。在运往伊利诺伊州芝加哥的林肯公园动物园进行分析之前，将从卢旺达的样本中提取激素。父亲的角色在非人类灵长类物种中是可变的，但迄今为止，对非一夫一妻制物种和类人猿的研究很少。山地大猩猩是一个有趣的研究物种，因为它们高度灵活的社会结构，其中包括多个和单一的男性群体，因此与人类交配系统的变化有相似之处。这个项目将让我们深入了解不同交配系统中父亲行为的起源，以及它对后代的短期和长期影响。该奖项将提供支持，使有前途的学生建立一个强大的独立的研究生涯。
