Abstract

The non-indigenous tanaidacean crustacean Sinelobus vanhaareni Bamber, 2014 was first found in northern Europe in 2006 and has since spread to the northern Baltic Sea. Here, we surveyed the distribution of the species in different habitats in southwestern Finland, focusing on vegetated macroalgal and seagrass habitats (i.e., Fucus vesiculosus beds and Zostera marina meadows). We also evaluated its potential impacts by synthesizing current knowledge on the traits and ecology of the species, and identified knowledge gaps. We found that S. vanhaareni is now present throughout most of the southwestern Finnish coast, in a number of vegetated and non-vegetated substrates down to 25 m depth. Furthermore, the presence of egg-brooding females in most areas also confirms that the population is self-sustaining. The species is especially abundant in shallow macroalgal belts and eelgrass meadows, which are critical habitats for biodiversity, ecosystem functioning, and ecosystem service provisioning, highlighting the need to understand the effects of S. vanhaareni in these important ecosystems. Its presence on boat hulls and in marinas and harbours suggests that recreational boating may be a major spread vector, while drifting macroalgal fragments may also contribute to regional spread. At this stage of invasion, we found high overlap in epifaunal community composition in sites where S. vanhaareni was present and sites where it was absent. Based on the functional traits of S. vanhaareni and closely related species, we infer that it is likely part of the detritus-based pathway in benthic food webs. However, additional sampling and experiments are necessary to determine the true extent of its distribution and to quantify trophic links (through stable isotope analysis, gut content analysis, and experimental trials) to fully understand its effects on communities and trophic networks in the northern Baltic Sea.
波罗的海北部新近引进的tanaidaceae甲壳类动物Sinelobus vanhaareni Bamber的分布和生态
这种非本地的tanaidae甲壳类动物Sinelobus vanhaareni Bamber, 2014于2006年首次在北欧被发现,此后扩散到波罗的海北部。本研究调查了该物种在芬兰西南部不同生境的分布情况,重点调查了植被覆盖的大藻和海草生境(即Fucus vesiculosus床和Zostera marina草甸)。我们还通过综合现有的物种特征和生态知识来评估其潜在影响,并确定知识空白。我们发现S. vanhaareni现在出现在芬兰西南海岸的大部分地区,在深度为25米的许多植被和非植被基质中。此外,在大多数地区,产卵的雌性也证实了种群是自我维持的。该物种在浅层大藻带和大叶藻草甸中尤其丰富,这是生物多样性、生态系统功能和生态系统服务提供的关键栖息地,突出了了解S. vanhaareni在这些重要生态系统中的影响的必要性。它在船体、码头和港口的存在表明,休闲划船可能是主要的传播媒介,而漂浮的大藻碎片也可能有助于区域传播。在入侵的这一阶段,我们发现在有范氏弧菌的地点和没有范氏弧菌的地点,地外群落组成高度重叠。基于S. vanhaareni及其近缘种的功能特征,我们推测它可能是底栖动物食物网中以碎屑为基础的途径的一部分。然而,需要更多的采样和实验来确定其分布的真实范围,并量化营养联系(通过稳定同位素分析、肠道内容分析和实验试验),以充分了解其对波罗的海北部群落和营养网络的影响。

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
