Abstract

West Indian manatees (Trichechus manatus) are separated into two allopatric subspecies: the Florida manatee (T. m. latirostris) and the Antillean manatee (T. m. manatus). In the winter of 2020–2021, an adult manatee was sighted off the coast of Cancun, Quintana Roo, Mexico, in areas where Antillean manatees are not typically seen. The individual had distinct watercraft scars on its body, which were matched using photo-identification to a known male Florida manatee (PE424) that had been repeatedly photographed in Florida since 1998. This is the first record of a Florida manatee visiting the Mexican Caribbean. Previous reports of individuals from this subspecies in Cuba, combined with genetic evidence, suggest some level of connectivity among geographically separated manatee populations. Highlights We present the first evidence of a long-distance movement by a manatee from Florida to the Yucatan Peninsula (Quintana Roo, Mexican Caribbean). This case, previous reports of Florida manatees in Cuba, and genetic evidence, suggest a certain degree of genetic mixture among the two subspecies.

佛罗里达海牛长途旅行到墨西哥加勒比海的第一个记录

西印度海牛(Trichechus manatus)被分为两个异质亚种:佛罗里达海牛(t.m. latirostris)和安的列斯海牛(t.m. manatus)。在2020-2021年的冬天，在墨西哥金塔纳罗奥州坎昆海岸附近发现了一只成年海牛，而安的列斯海牛通常不会出现在这些地区。这只海牛的身体上有明显的船只伤痕，通过照片识别与一只已知的雄性佛罗里达海牛(PE424)相匹配，这只雄性海牛自1998年以来在佛罗里达多次被拍到。这是佛罗里达海牛造访墨西哥加勒比海地区的首次记录。先前在古巴对这一亚种个体的报道，结合遗传证据，表明在地理上分开的海牛种群之间存在一定程度的连通性。我们提出了海牛从佛罗里达到尤卡坦半岛(墨西哥加勒比海金塔纳罗奥)长距离运动的第一个证据。这个案例，先前关于古巴佛罗里达海牛的报道，以及遗传证据表明，这两个亚种之间存在一定程度的遗传混合。

期刊介绍： Ethology Ecology & Evolution is an international peer reviewed journal which publishes original research and review articles on all aspects of animal behaviour, ecology and evolution. Articles should emphasise the significance of the research for understanding the function, ecology, evolution or genetics of behaviour. Contributions are also sought on aspects of ethology, ecology, evolution and genetics relevant to conservation. Research articles may be in the form of full length papers or short research reports. The Editor encourages the submission of short papers containing critical discussion of current issues in all the above areas. Monograph-length manuscripts on topics of major interest, as well as descriptions of new methods are welcome. A Forum, Letters to Editor and Book Reviews are also included. Special Issues are also occasionally published.
