摘要

群居动物的附属行为可能有几种功能，如维持社会联系、减少紧张或恢复关系。常见的宽吻海豚(Tursiops truncatus)会有几种亲密的行为，包括平行游泳、接触游泳和摩擦鳍。海豚在攻击后与以前的对手结盟，这表明这是一种缓解紧张的功能。本研究探讨攻击后的依恋行为是如何发生的。攻击后平行游泳的发生频率高于预期，而接触游泳和脚蹼摩擦的发生频率低于预期。平行游泳和接触游泳在攻击后立即发生;相比之下，摩擦鳍往往发生在攻击后一分钟以上。这些结果表明，当社会紧张加剧时，普通宽吻海豚会进行平行游泳和接触游泳。这些附属行为的功能可能不同，海豚可能在攻击后参与特定的附属行为。

Affiliative Behavior After Aggressions in Common Bottlenose Dolphins (Tursiops truncatus)

Affiliative behavior in social animals may have several functions such as maintaining social bonds, reducing tensions, or restoring relationships. Common bottlenose dolphins (Tursiops truncatus) engage in several affiliative behaviors, including parallel swimming, contact swimming, and flipper rubbing. Dolphins affiliate with former opponents after aggression, suggesting that this is a function of tension reduction. This study investigated how affiliative behaviors occur after aggression. Parallel swimming occurred more frequently than expected after aggression, while contact swimming and flipper rubbing occurred less frequently than expected. Parallel swimming and contact swimming occurred immediately after aggression; in contrast, flipper rubbing tended to occur more than one minute after aggression. These results suggest that common bottlenose dolphins engage in parallel swimming and contact swimming when social tension increases. The function may differ among these affiliative behaviors, and dolphins may engage in specific affiliations after aggression.

期刊介绍： Aquatic Mammals is a peer-reviewed journal sponsored by the European Association for Aquatic Mammals (EAAM), the Alliance of Marine Mammal Parks and Aquariums (AMMPA), and the International Marine Animal Trainers’ Association (IMATA). Aquatic Mammals publishes articles related to marine mammals (whales, dolphins, seals, fur seals, sea lions, walrus, dugongs, manatees, sea otters, and polar bears). Topics of publication on both captive animals and wild marine mammals include aspects of husbandry; behavior; conservation; veterinary medicine; anatomy; physiology; training; population trends; and the effects of pollution, climate change, and noise.
