While it has been supposed that loggerheads frequent this area only during the warmest months and then undertake seasonal migrations towards southern (warmer) waters, the occurrence of such migrations have never been demonstrated. On the other hand, the fact that loggerheads are found in Tuscany waters throughout the year (winter months included) can indicate that the picture is more complex and variable than previously supposed. The aim is to localize the areas frequented by loggerheads in the Northern Tyrrhenian Sea, to document the occurrence of seasonal migrations and/or to investigate the turtles&#039; fidelity to specific feeding areas.原始提供方：保罗·卢斯基（Paolo Luschi） 数据集署名信息： 数据提供方：比萨大学生物系伊斯兰塔集团（Islameta Group, Dept. of Biology - University of Pisa） 原始数据中心：<a href="http://www.seaturtle.org/tracking/" target="_blank">卫星跟踪与分析工具（Satellite Tracking and Analysis Tool, STAT）</a> 项目合作方：意大利格罗塞托水族馆海洋海龟救助中心（Centro Recupero Tartarughe Marine, Acquario di Grosseto, Italy） 摘要： 目前学界对栖息于第勒尼安海北部（地中海中部）托斯卡纳沿岸海域的大量红海龟（loggerhead）幼体的移动模式几乎一无所知。此前学界推测，红海龟仅在暖季活动于该海域，随后会向南部水温更高的海域开展季节性迁徙，但此类迁徙行为从未得到实证验证。另一方面，全年（含冬季）均可在托斯卡纳海域观测到红海龟的事实表明，其生存图景远比此前推测的更为复杂多变。本研究旨在定位红海龟在第勒尼安海北部的栖息区域，记录其季节性迁徙行为，并探究海龟对特定觅食区域的栖息忠实性。
