项目摘要
Mateo 9808704Many species, including humans, can discriminate among individuals according to genetic relatedness. Yet how this kin recognition is accomplished remains largely unexplored. Spermophilus beldingi are group-living squirrels that exhibit many forms of nepotism (favoritism directed at kin), including territory defense and predator avoidance, which require the ability to identify relatives. These studies will determine how this species uses odors for recognition, examine the limits of kin discrimination, and describe the development of both kin-based odors and kin recognition. Odor production and perception will be studied with controlled odor presentations to captive S. beldingi, and these results will be complemented by observations of free-living animals.When these studies are completed, S. beldingi will be one of the first organisms for which we have a thorough understanding of favoritism based on kinship that spans both mechanistic and evolutionary explanations for kin recognition. The results can be applied to other species that are threatened with extinction, as an understanding of how individuals use space and communicate with olfactory cues may be critical to the maintenance or relocation of populations. Finally, kin-recognition research may shed light on controversies among scientists who attempt to explain human behavior in an evolutionary framework; namely, how and why humans would either advertise or conceal their relatedness to others.
马特奥9808704许多物种,包括人类,可以根据遗传相关性来区分个体。然而,这种亲属识别是如何实现的,在很大程度上还没有被探索。黄鼠(Spermophilus beldingi)是群居的松鼠,表现出多种形式的裙带关系(偏袒亲属),包括领土防御和捕食者回避,这需要识别亲属的能力。这些研究将确定该物种如何使用气味进行识别,检查亲属歧视的限制,并描述基于亲属的气味和亲属识别的发展。气味的产生和感知将被研究与控制气味介绍圈养S。beldingi,这些结果将补充观察自由生活的动物。贝尔丁吉将是第一个我们对基于亲属关系的偏袒有透彻理解的生物之一,这种理解涵盖了对亲属识别的机械和进化解释。这些结果可以应用于其他面临灭绝威胁的物种,因为了解个体如何使用空间和与嗅觉线索进行交流可能对种群的维持或迁移至关重要。最后,亲属识别研究可能会揭示试图在进化框架中解释人类行为的科学家之间的争议;即,人类如何以及为什么会宣传或隐藏自己与他人的亲缘关系。
