Identifying coastal tracts suitable for sea turtle reproduction is crucial for sea turtle conservation in a context of fast coastal development and climate change. In contrast to nesting aggregations, diffuse nesting is elusive and assessing nesting levels is challenging. A total of 323 nesting events by the loggerhead sea turtle have been reported in Sicily, the largest Mediterranean island, in the 1944-2021 period, mostly in the last decade. Specific monitoring efforts are the most likely explanation for such an increase and shows that sea turtle nesting may be underestimated or completely ignored in many areas with scattered nesting. The real nesting level along the 464 km sandy shores of Sicily is still unknown and more research is needed. The observed incubation period was relatively long (57 d) suggesting that a majority of males are produced in Sicily, in contrast to the typical female-biased sex ratio of sea turtles. In a context of climate warming producing sex ratios more skewed towards females, the potential of Sicily as a male-producing area should be further investigated. Other reproductive parameters are provided, such as clutch size and hatching and emergence success. A negative effect of relocation on the latter two was observed.
在沿海快速发展和气候变化的背景下，识别适合海龟繁殖的沿海区域对海龟保护至关重要。与筑巢聚集不同，分散筑巢难以捉摸，评估筑巢水平具有挑战性。在1944年至2021年期间，地中海最大的岛屿西西里岛共报告了323起蠵龟筑巢事件，大部分发生在过去十年。这种增加最可能的原因是特定的监测工作，这表明在许多分散筑巢的地区，海龟筑巢情况可能被低估或完全被忽视。西西里岛464公里长的沙质海岸的实际筑巢水平仍然未知，需要更多的研究。观察到的孵化期相对较长（57天），这表明西西里岛产出的雄性海龟占多数，这与海龟典型的雌性偏向性别比例不同。在气候变暖导致性别比例更偏向雌性的背景下，西西里岛作为雄性海龟产出地的潜力应进一步研究。还提供了其他繁殖参数，如窝卵数、孵化成功率和出壳成功率。观察到转移对后两者有负面影响。
