Satellite tagging of female hawksbill sea turtles (Eretmochelys imbricata) nesting on Groote Eylandt, Northern Territory, 2009-2011

Hawksbill turtles are classified Critically Endangered by the IUCN following intense commercial exploitation that decimated global stocks. Despite Australia supporting one of the largest breeding aggregations worldwide, hawksbill turtle biology and ecology remains poorly documented, especially for populations nesting in the Northern Territory. This study focused on the internationally significant hawksbill turtle population breeding in Groote Eylandt in the Gulf of Carpentaria, and aimed at providing high resolution information for managing this critically endangered species. By using multiple state-of-the-art analytical frameworks and combining satellite telemetry, hydrological modelling, and tag recapture data, we (i) assessed habitat utilisation during the inter-nesting and foraging periods, (ii) quantified migratory behaviour for better understanding of navigational strategies , and (iii) simulated post-hatchling dispersal patterns, which we subsequently compared to the location of adult foraging grounds.

玳瑁龟因高强度商业捕捞导致全球种群锐减，被世界自然保护联盟（International Union for Conservation of Nature, IUCN）列为极危（Critically Endangered, CR）物种。尽管澳大利亚拥有全球规模最大的玳瑁龟繁殖集群之一，但学界对玳瑁龟的生物学与生态学特征仍研究记录匮乏，针对北领地筑巢种群的相关研究尤为不足。本研究聚焦于卡奔塔利亚湾格鲁特岛的国际重要玳瑁龟繁殖种群，旨在为这一极危物种的保护管理提供高精度科研数据。本研究采用多种顶尖分析框架，结合卫星遥测、水文模拟与标记重捕数据，开展了三项核心研究：(1) 评估玳瑁龟在筑巢间期与觅食期的栖息地利用模式；(2) 量化其迁徙行为，以深入解析其导航策略；(3) 模拟幼龟孵化后的扩散格局，并将模拟结果与成体觅食地的空间位置进行对比分析。
