In the 2020 summer the territory of Sicily was affected by a strong drought which caused a strong lowering of the level of the water bodies of the whole Region; the protected area of Vendicari (S-E Sicily) was not spared by these events. Furthermore, a strong storm affected the coasts of southeastern Sicily. These meteorological events, drought and storm, acted synergistically causing the silting up of the mouth of the coastal pond Pantano Sichilli which represents for the latter the only way of communication with the sea. Therefore, the water level of the Marsh has drastically dropped causing, directly or indirectly, the death of several tens of thousands of aquatic organisms that populate them such as fish, crabs, molluscs, etc. Among these, our attention was drawn to the remains of thousands of specimens of the voracious Atlantic blue crab of the Callinectes sapidus species. Following these events, linked to the climate, it was possible to detect, for the first time, the presence of C. sapidus in the Vendicari ponds and to formulate hypotheses on the great abundance of individuals of this species which could represent a strong threat to the biodiversity of these environments.

在2020年夏季，西西里岛领土受到强烈干旱的影响，导致整个地区水体水平大大降低；这些事件并没有使旺迪卡里（西西里岛）的保护区幸免。此外，一场强风暴影响了西西里岛东南部的海岸。这些干旱和暴风雨的气象事件协同作用，导致沿海池塘Pantano Sichilli的河口淤积，这是后者与大海沟通的唯一方式。因此，沼泽的水位急剧下降，直接或间接地导致了成千上万的水生生物死亡，例如鱼，螃蟹，软体动物等。其中，in（Callinectes sapidus）种。在这些与气候有关的事件发生之后，有可能首次检测到文迪卡里池塘中的美人鱼（C. sapidus）的存在，并提出了关于该物种个体大量存在的假说，这些假说可能是对沙门氏菌的强烈威胁。这些环境的生物多样性。
