摘要:
动物对后代的抚育和互动行为是提高后代成活率和保证基因延续的重要方式,因此动物在自己的存活基础上,还要抚幼和照料后代. 2014年5月—2015年6月,采用目标动物取样法对生活在铜陵淡水豚国家级自然保护区半自然水域的两对母幼豚的互动行为进行初步研究. 结果表明,长江江豚母、幼豚间的背驮、伴游、干涉行为具有明显的周期性. 在幼豚前2月龄,干涉行为和背驼行为比较多,可能是刚出生不久的幼豚活动能力有限,需要母豚的直接干预; 在幼豚前6月龄前伴游行为常见,全年均可常见身体触碰行为. 同时发现,随着幼豚月龄增加,幼豚与母豚的分离时间也有所增加. 本研究提供了半自然环境下母幼豚的互动行为方式,对江豚的异地保护与管理具有一定的参考价值.
Abstract:
Breeding and offspring-nurture is the only way for animals to keep their genes alive,so animals not only ensure their own survival but also need to keep their offspring's survival. From May of 2014 to June of 2015,the study separately chose coastal stationary and mobile tracking methods to observe two adult female Yangtze Finless Porpoise(Neophocaena asiaeorientalis)by focal-animal sampling methods in a semi-natural water in Tongling Freshwater Dolphins National Nature Reserve. The result showed there were rich breeding behaviors in female Finless Porpoises living in semi-natural water area. The main maternal behaviors were pack,intervene,accompanying swim and physical touch. Accompanying swim and physical touch could be observed during the whole study. The study also found that the separation time of calf and mother was significantly positively correlated with the monthly age of calf dolphins. This study provides the interaction mode of mother and calf dolphins in semi-natural water enviroment,which has certain reference value for the remote protection and management of Yangtze Finless Porpoise.
