The land snails (Mollusca, Gastropoda) of Kea island (Aegean, Greece)

Kea is the westernmost island of the Cyclades and is located between Syros and Attica, in central Greece. In this work, we have resampled the island after 43 years – i.e. when the island was first fully sampled – and we present its complete land snail fauna.We report 42 land snail species with 10 species being new records for the island. Based on our results we draw attention to the fact that sampling for land snails should be done during the wet period in order to survey the complete malacofauna in an island or a region. For such a complete survey, collection and inspection of soil and litter are also necessary. Finally, increased sampling effort through regular resurveys is a necessary prerequisite in order to effectively assess the temporal dynamics of biodiversity patterns.

卡亚岛是基克拉泽斯群岛最西端的岛屿，位于希腊中部的叙罗斯和阿提卡之间。在本研究中，我们对岛屿进行了43年后的重采样——即岛屿首次全面采样时——并展示了其完整的陆生蜗牛群落。我们报告了42种陆生蜗牛物种，其中10种为该岛的新记录。基于我们的研究结果，我们强调，在调查岛屿或地区的完整软体动物群落时，采样应在湿润期间进行。为了进行如此全面的调查，收集和检查土壤和落叶也是必要的。最后，通过定期复样增加采样力度，是有效评估生物多样性模式时间动态的必要前提。
