There have been multiple paternity studies across many taxa, including birds, reptiles and insects, for many decades. Sea turtles are by far the most studied of any group of reptiles with up to ten fathers recorded for a clutch and multiple paternity in over 90% of clutches in some populations. Whether multiple paternity has any adaptive significance remains a key question in sea turtles, since the impact of environmental conditions often seems to swamp any impact of the incidence of multiple paternity. Climate warming and the resulting threat of feminisation of sea turtle populations is set to provide an intense new focus for studies. If male turtles become increasingly scarce as a result of warming incubation temperatures, then management intervention will be needed to promote male hatchling production. Multiple paternity studies may help inform when intervention is needed, with the expectation that the incidence of multiple paternity will decline as breeding males become scarce.
几十年来,包括鸟类、爬行动物和昆虫在内的多个分类群已经进行了多次亲子鉴定研究。海龟是迄今为止研究最多的爬行动物群体,多达 10 个父亲记录在一个窝中,在一些种群中,超过 90%的窝中存在多父系。多父系是否具有任何适应性意义仍然是海龟研究中的一个关键问题,因为环境条件的影响似乎常常超过多父系发生率的任何影响。气候变暖以及由此产生的海龟种群雌性化的威胁,将为研究提供一个新的强烈焦点。如果由于孵化温度升高导致雄性海龟变得越来越稀缺,那么就需要进行管理干预来促进雄性幼龟的生产。多父系研究可以帮助了解何时需要干预,预期随着繁殖雄性变得稀缺,多父系的发生率将会下降。
