Aggression Mate Guarding Male Parental

项目摘要

This research project will test four hypotheses about evolutionary forces that affect the behavior of pair-bonded birds to each other and to the nestlings they raise: 1. Male-male aggression during a female's fertile period decreases the likelihood that the female's young are sired by males other than her territorial partner. 2. Female-female aggression during the egg-laying period functions to decrease the likelihood that females' broods contain nestlings from other females of the same species that lay their eggs in the nests of neighbors. 3. Mate- guarding by males is a response to females' behavior or ecological circumstances that increase the likelihood that females mate with more than one male. 4. Parental feeding of nestlings by males varies according to males' likelihood of genetic paternity as indicated by the behavior of females when they are fertile. These are important questions for several reasons. Dr. Gowaty and her colleagues are attempting to observe evolutionary processes as they occur, by testing the current functional utility and evolutionary significance of important, sometimes dramatic, social behaviors. Also, the researchers are testing hypotheses about the relationship of "confidence of paternity" (the perceived likelihood that a male is the actual genetic sire of the offspring he cares for) to actual genetic paternity as assessed using DNA markers. This in turn is important because ideas about confidence of paternity are theoretically prominent explanations for variation in the social behavior of male animals.

该研究项目将测试四个假设，影响成对鸟类行为的进化力量他们彼此之间，彼此之间。雄性跟在女性的生育期的侵略减少了雌性幼崽由除雄性之外的雄性所生的可能性她的领土伙伴。 2. 女性对女性的攻击产卵期的作用是降低雌鸟的窝里有来自同一个种群的其他雌鸟的雏鸟在邻居的巢穴中产卵的物种。 3. 伙计- 雄性守卫是对雌性行为的反应，生态环境增加了雌性与不止一只雄性交配 4. 父母喂养根据雄性的可能性，遗传父系，如女性的行为所表明的，他们是肥沃的。这些都是重要的问题，原因有几个。 Gowaty医生和她的同事们正试图观察进化通过测试当前的功能，实用性和进化意义的重要，有时戏剧性的社会行为此外，研究人员正在测试 “亲子关系置信度”关系假说 (the认为一个男性是真正的遗传父亲的可能性他所照顾的后代）到实际的遗传亲子关系，使用DNA标记进行评估。这一点很重要，因为亲权认定的观点在理论上是突出的对男性社会行为变异的解释动物
