Abstract

Jezero Blaca is a unique spring lake situated at the northern coast of the Pelješac Peninsula near the village Duba Pelješka in South Dalmatia, Croatia. The lake supported by a karstic spring located near the Adriatic seashore is inhabited by unusually rich brackish water truncatelloid assemblage. The position of the lake near seashore evokes a model of sea invertebrate gradual adaptation to freshwater spring head allowing them to further invade the stygobiont karst conduits. Similar lakes could be the marine gateways of the extraordinarily rich Dinaric stygobiont fauna. The main aim of this study was to sample and barcode the aquatic snails found in this locality to check their species affiliation and describe conservation needs. The results confirmed that the locality hosts four interesting representatives of the gastropod superfamily Truncatelloidea, which has never been found syntopically so far. One of the species characterized by unique COI sequences and was described herein as Truncatella dalmatica new sp. The conservation need of this unique and understudied habitat type is discussed.

位于佩列沙茨半岛的克罗地亚咸水喀斯特泉湖杰泽罗-布拉卡揭示了有趣的腔肠动物腹足纲集合体

杰泽罗-布拉卡是一个独特的泉水湖，位于克罗地亚南达尔马提亚杜巴-佩列什卡村附近的佩列沙茨半岛北岸。这个由喀斯特泉水支撑的湖泊靠近亚得里亚海海岸，湖中栖息着异常丰富的咸水蝶类。该湖靠近海边的位置使人联想到海洋无脊椎动物逐渐适应淡水泉水头的模式，从而使它们能够进一步侵入岩溶通道。类似的湖泊可能是异常丰富的第纳尔风格无脊椎动物群的海洋门户。这项研究的主要目的是对在该地区发现的水生蜗牛进行采样和条形码编码，以检查它们的物种归属并描述保护需求。研究结果证实，该地点栖息着四个有趣的腹足类超家族 Truncatelloidea 的代表物种，迄今为止还从未发现过与该超家族同源的物种。其中一个物种具有独特的 COI 序列，被描述为 Truncatella dalmatica new sp。

期刊介绍： Aquatic Conservation: Marine and Freshwater Ecosystems is an international journal dedicated to publishing original papers that relate specifically to freshwater, brackish or marine habitats and encouraging work that spans these ecosystems. This journal provides a forum in which all aspects of the conservation of aquatic biological resources can be presented and discussed, enabling greater cooperation and efficiency in solving problems in aquatic resource conservation.
