摘要

摘要/ Abstract摘要:本研究分析了2006 - 2014年巴西东北部沿海地区8个筑巢季节150只玳瑁(Eretmochelys imbricata)的410个巢点，以评估其筑巢偏好。我们确定了开放式沙巢和植被巢微生境的巢址选择在筑巢季节内和之间的一致性，以及巢址与当前水线、最高大潮、植被线和沿海滩位置的距离。我们发现季节内的行为一致性比季节之间的行为一致性更强。这表明，筑巢地点选择一致性的降低可能与筑巢环境的渐进式景观变化有关，从而推动了筑巢偏好的行为灵活性。

Individual Nest Site Selection in Hawksbill Turtles Within and Between Nesting Seasons

Abstract We analyzed 410 nest locations from 150 individual nesting hawksbill turtles (Eretmochelys imbricata) on the northeastern Brazilian coast during 8 nesting seasons from 2006 to 2014 to evaluate individual nesting preferences. We determined the consistency of nest site choice within and between nesting seasons for open sand and vegetation nest microhabitats and also for nest site distances from the current waterline, highest spring tide, vegetation line, and position along the beach. We found that behavioral consistency within seasons was more robust than between seasons. This suggests that a decrease in the consistency of nest site choice may be related to progressive landscape changes in the nesting environment, driving behavioral flexibility in nesting preferences.

期刊介绍： Chelonian Conservation and Biology is a biannual peer-reviewed journal of cosmopolitan and broad-based coverage of all aspects of conservation and biology of all chelonians, including freshwater turtles, marine turtles, and tortoises. Manuscripts may cover any aspects of turtle and tortoise research, with a preference for conservation or biology. Manuscripts dealing with conservation biology, systematic relationships, chelonian diversity, geographic distribution, natural history, ecology, reproduction, morphology and natural variation, population status, husbandry, community conservation initiatives, and human exploitation or conservation management issues are of special interest.
