9311508 Holmes Alarm calls are vocalizations elicited by predators that can alert other members of the species to impending danger. Alarm calls have functional value only if they are responded to appropriately for the type of predator. Ms. Jill M. Mateo's doctoral-dissertation research seeks to determine when and how responses to alarm calls develop in young Belding's ground squirrels, as her pilot data show that alarm-call responses are not fully developed when young ground squirrels first emerge from the burrow where they were born. Ms. Mateo will test three predictions about the relative importance of auditory experience and social context for the development of alarm-call responses: (1) experience with the mother's vocalizations before weaning helps the young to discriminate alarm calls after weaning; (2) development of alarm-call responses after weaning is socially facilitated by observing adult alarm-call responses, and (3) the quality of juvenile alarm-call responses improves rapidly if they repeatedly hear alarm calls in the presence of other responding individuals. These predictions will be tested by playing back tape-recordings of alarm calls and recording the cardiac responses of unweaned pups and the behavioral responses of juveniles housed in a semi-natural environment or living in the field. Results will help explain how social influences contribute to the development of a critical survival skill, and will advance our understanding of how behavior develops through tightly-woven interactions between the organism and the series of environments it encounters throughout its life.

9311508 Holmes警报电话是由掠食者引起的，可以提醒该物种的其他成员即将发生的危险。 仅当对捕食者的类型进行适当响应时，警报呼叫才具有功能值。 吉尔·M·马特奥（Jill M. Mateo）女士的博士学位研究旨在确定年轻贝尔丁（Belding）地下松鼠中对警报呼叫的何时以及如何形成，因为她的飞行员数据表明​​，当年轻的地下松鼠首先从burrow中出现时，警报通话的反应并未完全开发。 Mateo女士将测试有关听觉经验和社会环境对开发警报通话回应的相对重要性的三个预测：（1）在断奶之前，母亲发声的经验可以帮助年轻人在断奶后歧视警报呼叫； （2）通过观察成人警报呼叫的响应来促进断奶后的警报通话反应，以及（3）如果在其他反应的个人在场的情况下，他们反复听到警报呼叫，少年警报呼叫响应的质量会迅速提高。 这些预测将通过播放警报呼叫的背部录音并记录不安的幼崽的心脏反应以及在半自然环境中或生活在现场生活的少年反应来测试这些预测。 结果将有助于解释社会影响如何有助于发展关键生存技能的发展，并将通过生物体与它一生所遇到的一系列环境之间的紧密编织相互作用来促进我们对行为如何发展的理解。
