Accurate quantification of the species' habitat requirements, typically achieved through home range (HR) estimation, is required to implement area-based conservation initiatives. In this study, we used GPS tracking data from 38 wild and captive-rehabilitated released manatees to estimate HR using autocorrelated kernel density estimators (AKDE) and average time speed. We investigated whether body size, habitat type, sex and behavioural group influence home range size due to energy requirements, resources availability, a scramble-competitive polygyny mating system, and adaptation to the wild. Eighteen manatees exhibited range-resident behaviour, with a mean 95% home range of 72.96 km2 (± 218.52) and a median of 10.69 km2. The mean daily speed was estimated to be 13.47 km/day (± 4.16). Home range and body size were positively correlated, consistent with HR allometry theory. Long-term tracked individuals showed a trend of increasing HR over time. Only four released animals (17.4%) were range-resident, suggesting that they may need additional time to establish a home range. Individuals using only the marine environment had larger home ranges compared to mixed (marine and estuarine) and estuarine environments, probably due to freshwater availability. Our study contributes to the understanding of the factors driving manatee movement and provides more accurate estimates of area requirements, which can inform the establishment and zoning of marine protected areas.","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141245823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although a gradual downward trend in catches of O. cyanea in the Ryukyu Archipelago has been reported, no study has focused on the connectivity and genetic structure, which are important parameters for conservation strategies. We used partial sequences of mitochondrial COI and MIG-seq, which can efficiently obtain single nucleotide polymorphism (SNPs) to evaluate genetic diversity and patterns of gene flow among three populations of O. cyanea in the Ryukyu Archipelago. We combined population genetic analyses with biophysical approaches to understand larval dispersal patterns and the regional connectivity. Although there was a tendency for the Yaeyama population to become isolated from the Okinawa-jima populations, high genetic diversity was maintained overall, indicating frequent genetic exchange between populations. Population genetic analyses combined with larval dispersal simulations revealed that the contemporary migration of O. cyanea is asymmetric patterns among the three populations, suggesting that western coast of Okinawa-jima Island functions as a source population among the three populations we examined. The potential implications of this study on the conservation management of O. cyanea were discussed, namely that future population assessment approaches are needed to include western coast of Okinawa-jima populations. In addition, this study indicates that at least two different management units should be considered. This study is the first population genetic study of O. cyanea in the Ryukyu Archipelago and provides fundamental information on the genetic population structure of this species in this region.","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141078930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
