Abstract

Though the morphological discrimination of the three pseudo-cryptic Ammonia species, A. aberdoveyensis , A. confertitesta and A. veneta , has been recently established, information on their ecology and habitats are still relatively scarce. This study aims to define distribution patterns of these species at eight sites scattered along the French coasts of the English Channel, over a total of 39 stations. These sites were classified into two habitats, either harbours (heavily modified sites) or less impacted (moderately influenced sites). The use of IndVal index (an index based on how a species is statistically specific to a habitat) clearly indicates that A. confertitesta is recorded preferentially in or close to harbours. Considering its non-indigenous species (NIS) status in Europe, we investigated its reported occurrences in Europe in the literature. It almost always showed a proximity to major European harbours. Sometimes, this species occurred relatively far away from these harbours, suggesting a secondary spread. Finally, this work interprets A. confertitesta being a NIS in the eastern English Channel with assumptions of being invasive regarding its dominance over the indigenous species A. aberdoveyensis and A. veneta . Complementary works such as retrospective core studies of fossil faunas are needed to quantitatively assess when and where A. confertitesta was introduced in Europe and potentially started to replace its congenerics A. veneta and A. aberdoveyensis .

Preferential在港口的存在证实了英吉利海峡氨孔虫(有孔虫)的非本地物种地位
虽然最近已经建立了A. aberdoveyensis、A. confertitesta和A. veneta三种拟隐氨物种的形态区分,但关于它们的生态和栖息地的信息仍然相对缺乏。这项研究旨在确定这些物种在英吉利海峡法国海岸分布的八个地点的分布模式,总共有39个站点。这些地点被分为两种栖息地,要么是海港(严重改变的地点),要么是受影响较小的地点(中等影响的地点)。使用IndVal指数(一种基于物种在统计上如何特定于栖息地的指数)清楚地表明,褐刺刺槐优先记录在港口或靠近港口。考虑到其在欧洲的非本地种(NIS)状况,我们调查了其在欧洲文献报道的发生情况。它几乎总是显示靠近欧洲主要港口。有时,该物种发生在离这些港口相对较远的地方,表明二次传播。最后,本研究将a . confertitesta解释为英吉利海峡东部的NIS,并假设其对本地物种a . aberdoveyensis和a . veneta具有入侵性优势。补充工作,如对化石动物群的回顾性核心研究,需要定量评估A. conftitesta在何时何地被引入欧洲,并可能开始取代其同属A. veneta和A. aberdoveyensis。

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
