与亲属和非亲属生活在一起的动物应该根据直接和间接适应性的后果做出社会决策。常见的吸血蝙蝠，Desmodus rotundus，投资于稳定的合作关系，有利于包容性健身的两个组成部分。为了解开这两个因素，我们进行了两种类型的播放试验，使用一组熟悉的普通吸血蝙蝠与混合亲属关系和不同比率的二元食物共享。我们为每个受试者提供两个扬声器，播放来自两个不同的熟悉同种的联系电话。在“过去的捐赠者试验”中，15只吸血蝙蝠选择了来自频繁或罕见食物捐赠者的呼叫，但这两个呼叫者与受试者的关系程度相似。在“亲属关系试验”中，31只吸血蝙蝠在近亲或远亲的叫声中进行选择，但两个叫声都与受试者的食物共享历史相匹配。我们发现吸血蝙蝠在控制亲属关系时会被频繁食物捐赠者的联系电话所吸引，但在控制食物分享历史时不会被亲属的电话所吸引。反应和声学分析表明，蝙蝠通过发声识别个体。这些结果证实了过去的研究结果，即先前的食物分享可以掩盖吸血蝙蝠在决定社会决策方面的相关性。普通吸血蝙蝠的联络叫声可以让食物共享的伙伴在一定距离内认出并找到对方，这可能使它们能够在野外一起交换栖息地。(C)2016动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Animals living with kin and nonkin should make social decisions based on the consequences for both direct and indirect fitness. Common vampire bats, Desmodus rotundus, invest in stable cooperative relationships that benefit both components of inclusive fitness. To disentangle these two factors, we conducted two types of playback trials using a captive group of familiar common vampire bats with mixed kinship and varying rates of dyadic food sharing. We presented each subject with two speakers, playing contact calls from two different familiar conspecifics. In 'past donor trials', 15 vampire bats chose between calls recorded from either a frequent or rare food donor, but both callers were related to a similar degree with the subject. In 'kinship trials', 31 vampire bats chose between calls recorded from either a close or distant relative, but both callers were matched for food-sharing history with the subject. We found that vampire bats were attracted to contact calls of frequent food donors when controlling for kinship, but not to calls of kin when controlling for food-sharing history. Responses and acoustic analyses suggested that bats recognized individuals from vocalizations. These results corroborate past findings that prior food sharing can overshadow relatedness in determining the social decisions of vampire bats. Common vampire bat contact calls allow food-sharing partners to recognize and find each other at a distance, which likely enables them to switch roosts together in the wild.
