Adult sea turtles undertake periodic long-distance migrations between foraging and nesting areas during breeding migrations, and an understanding the connectivity between these two important habitats can contribute to efficient conservation planning. We present the first round-trip migrations of three green sea turtles in the Arabian region, from a foraging area to a nesting site and back, along with an interpretation of reproductive behaviour which would not have been possible from open-ended tracks. We studied habitat connectivity between seagrass foraging areas in the UAE and nesting beaches, and used laparoscopy as a diagnostic tool to determine gender and reproductive state to enhance the value of satellite tracking data. We identify habitat connectivity between a foraging area at Bu Tinah in the UAE and a nesting site at Ras al Hadd in Oman, document migratory behaviour in the Arabian region, and demonstrate the enhanced value of combining laparoscopy when satellite tracking sea turtles from foraging areas. The results of our work can help develop bilateral or multi-lateral conservation strategies, contribute to the identification of Important Turtle Areas (ITAs), and support national and regional population assessments. In addition, our findings will complement risk assessments for sea turtles in the face of urban and industrial development, climate change, fishery pressure, and shipping activities. This work successfully linked foraging areas and nesting sites, and our approach can be used to provide value-added benefits to future tracking of sea turtles from foraging areas.

腹腔镜和卫星跟踪相结合:成功地对雌性绿海龟从觅食区到筑巢场和返回的往返跟踪

成年海龟在繁殖迁移期间会在觅食和筑巢区之间进行定期的长距离迁移,了解这两个重要栖息地之间的连通性有助于制定有效的保护计划。我们介绍了阿拉伯地区三只绿海龟从觅食区到筑巢地点再到其后的第一次来回迁移,以及对繁殖行为的解释,这是从开放式路线不可能实现的。我们研究了阿联酋海草觅食区和巢滩之间的栖息地连通性,并使用腹腔镜作为诊断工具来确定性别和生殖状态,以提高卫星跟踪数据的价值。我们确定了阿联酋Bu Tinah觅食区与阿曼Ras al Hadd筑巢点之间的栖息地连通性,记录了阿拉伯地区的迁徙行为,并证明了当卫星从觅食区追踪海龟时,结合腹腔镜检查具有更高的价值。我们工作的结果可以帮助制定双边或多边保护战略,有助于识别重要的海龟地区,并支持国家和地区的人口评估。此外,面对城市和工业发展,气候变化,渔业压力和航运活动,我们的发现将补充海龟的风险评估。这项工作成功地将觅食区和筑巢地点联系在一起,我们的方法可用于为将来从觅食区追踪海龟提供增值收益。并演示了当从觅食区跟踪海龟时,结合腹腔镜检查的增强价值。我们工作的结果可以帮助制定双边或多边保护战略,有助于确定重要的海龟地区(ITAs),并支持国家和地区的人口评估。此外,面对城市和工业发展,气候变化,渔业压力和航运活动,我们的发现将补充海龟的风险评估。这项工作成功地将觅食区和筑巢地点联系在一起,我们的方法可用于为将来从觅食区追踪海龟提供增值收益。并演示了当从觅食区跟踪海龟时,结合腹腔镜检查的增强价值。我们工作的结果可以帮助制定双边或多边保护战略,有助于确定重要的海龟地区,并支持国家和地区的人口评估。此外,面对城市和工业发展,气候变化,渔业压力和航运活动,我们的发现将补充海龟的风险评估。这项工作成功地将觅食区和筑巢地点联系在一起,我们的方法可用于为将来从觅食区追踪海龟提供增值收益。有助于确定重要的海龟区(ITAs),并支持国家和地区的人口评估。此外,面对城市和工业发展,气候变化,渔业压力和航运活动,我们的发现将补充海龟的风险评估。这项工作成功地将觅食区和筑巢地点联系在一起,我们的方法可用于为将来从觅食区追踪海龟提供增值收益。有助于确定重要的海龟区(ITAs),并支持国家和地区的人口评估。此外,面对城市和工业发展,气候变化,渔业压力和航运活动,我们的发现将补充海龟的风险评估。这项工作成功地将觅食区域和筑巢地点联系在一起,我们的方法可用于为将来从觅食区域追踪海龟提供增值收益。
