本数据集的相关研究方法详见手稿：Carter、Wilkinson、Page（2017）发表于学术期刊《行为生态学》（Behavioral Ecology）的论文《感知风险下共享食物的吸血蝙蝠更具亲缘偏好》（原文英文标题：Food-sharing vampire bats are more nepotistic under conditions of perceived risk）。
数据集各字段定义如下：
1. recipient：未进食蝙蝠（unfed bat）
2. donor：已进食蝙蝠（fed bat）
3. trt：接收者所处的处理条件，包含正常组与诱捕组两种情况（treatment (normal or trapped) condition for recipient）
4. trial：试验编号
5. donation：接收者舔舐供体口腔的总互动时长（仅统计时长大于5秒的互动回合），单位为秒（total trial seconds that recipient licks donor's mouth (only bouts >5 s)）
6. total.donations：所有供体向该接收者的累计捐赠总时长
7. donation.rate：捐赠速率，计算公式为捐赠时长除以试验总时长（以小时为单位），即 donations/(number trial hours)
8. prop.donation：捐赠占比，计算公式为单份捐赠时长除以对应接收者总捐赠时长，即 donation/total.donations
9. kinship：接收者与供体间的遗传亲缘关系值（genetic relatedness）
10. dyad：接收者-供体配对（recipient-donor pair）
