Abstract

The newly established population of Perna perna surveyed at four sites along the Israeli Mediterranean coast averaged between 2155 and 8022 specimens/m² in June 2021. Three sites displayed unimodal size–frequency distributions, whereas the site adjacent to Haifa port – a bimodal distribution. The population suffered catastrophic mortality following a succession of heatwaves culminating in a prolonged heatwave in August (ambient temperature 36 to 38 °C, sea surface 32 °C), with diurnal low tides occurring midday. With the projected rise in both mean temperature, and prevalence, duration, and severity of extreme high temperature events, it is likely that even if a P. perna reoccurs, it will be of brief duration.

今天在这里，明天就消失了——地中海的褐贻贝种群在前所未有的热浪中灭绝了

2021年6月，在以色列地中海沿岸的四个地点调查了新建立的Perna Perna种群，平均数量在2155至8022只/平方米之间。三个站点显示单峰大小-频率分布，而靠近海法港的站点显示双峰分布。在一连串的热浪之后，种群遭受了灾难性的死亡，最终在8月的长时间热浪中达到高潮(环境温度36至38°C，海面32°C)，白天的低潮发生在中午。随着预计的平均温度、极端高温事件的发生率、持续时间和严重程度的上升，即使P. perna再次发生，持续时间也很可能很短。

期刊介绍： Aquatic Invasions is an open access, peer-reviewed international journal focusing on academic research of biological invasions in both inland and coastal water ecosystems from around the world. It was established in 2006 as initiative of the International Society of Limnology (SIL) Working Group on Aquatic Invasive Species (WGAIS) with start-up funding from the European Commission Sixth Framework Programme for Research and Technological Development Integrated Project ALARM. Aquatic Invasions is an official journal of International Association for Open Knowledge on Invasive Alien Species (INVASIVESNET). Aquatic Invasions provides a forum for professionals involved in research of aquatic non-native species, including a focus on the following: • Patterns of non-native species dispersal, including range extensions with global change • Trends in new introductions and establishment of non-native species • Population dynamics of non-native species • Ecological and evolutionary impacts of non-native species • Behaviour of invasive and associated native species in invaded areas • Prediction of new invasions • Advances in non-native species identification and taxonomy
