Abstract:
A focus of this year's satellite tracking project is to compare stable isotope results with telemetry results to determine the efficacy of using stable isotopes to elucidate post-nesting migratory destinations of sea turtles. Stable isotope analysis of skin and eggshell tissue (which reflect foraging areas) will be compared with the oceanographic regions visited during satellite tracking. Stable isotope values that are consistently different for females in oceanic vs. neritic habitats lend credence to their use to infer post-nesting migratory destinations. A lack of matching between isotope values (pre-nesting habitat) and satellite tracks (post-nesting habitats) would suggest a) that loggerheads do not exhibit philopatry to foraging regions, or b) that loggerhead habitat use is too flexible to use isotopes in inferring habitat use. A consistent isotope-telemetry match among individuals would suggest that stable isotopes can be used in lieu of the more expensive satellite telemetry approach to potentially infer foraging grounds. A second focus is to track female turtles that are potentially bycatch in the Gulf of Mexico Reef Fish Fishery bottom longline fishery.

研究摘要：
本年度卫星跟踪项目的核心目标之一，是将稳定同位素分析结果与遥测数据进行对比，以验证稳定同位素法在阐明海龟筑巢后迁徙目的地方面的有效性。研究将针对皮肤与蛋壳组织（可反映海龟觅食区域）开展稳定同位素分析，并将分析结果与卫星跟踪期间记录的海洋学活动区域进行比对。若海洋生与浅海生境中的雌性海龟，其稳定同位素值存在显著且稳定的差异，则可证明该方法可用于推断其筑巢后的迁徙目的地。若同位素值（代表筑巢前生境）与卫星跟踪轨迹（代表筑巢后生境）之间缺乏匹配性，则可能存在两种情况：a) 蠵龟（loggerhead）并未表现出对觅食区域的归巢习性；或b) 蠵龟的生境利用模式过于灵活，无法通过同位素分析推断其生境选择。若个体间的同位素-遥测匹配结果具备一致性，则表明稳定同位素分析可替代成本更高的卫星遥测技术，以推断海龟的觅食区域。本项目的另一核心目标，是对可能在墨西哥湾礁鱼渔业底延绳钓作业中被兼捕的雌性海龟进行跟踪。有关该问题的更多信息可参阅<a href="http://sero.nmfs.noaa.gov/pr/TurtlesReefFish.htm">www.sero.nmfs.noaa.gov/pr/TurtlesReefFish.htm</a>
