摘要

Understanding使非本地物种(NIS)成功在接收社区建立的特征和条件是确定其对本地物种的潜在影响以及改善管理行动(如预防未来入侵)的关键。圆虾虎鱼(Neogobius melanostomus)是北半球分布最广的非本地鱼类之一,包括波罗的海沿岸地区。圆虾虎鱼在波罗的海的影响是明显和多方面的,但我们对决定其建立的基本组装过程的了解有限。为了克服这一知识差距,我们采用基于特征的方法,基于功能独特性度量来评估波罗的海沿海地区圆虾虎鱼与本地鱼类之间的生态位重叠程度和功能(特征)相似性。我们的研究结果表明,圆虾虎鱼通常与区域物种池中的本地鱼类非常相似(或没有不同),至少在其整体性状组成方面。相反,圆虾虎鱼在表现亲代关怀和领地行为方面与本地群体表现出明显的差异。这种个体特征的差异可能在圆虾虎鱼入侵波罗的海的成功中发挥重要作用,包括与本地物种的相互作用(例如竞争)。如果将我们的结果及其潜在影响与现有的生物入侵风险评估工具相结合,则可能与保护和管理高度相关,以便优先考虑并提高对圆虾虎鱼扩张的预防行动的有效性。

The devil is in the details: exploring how functionally distinct round goby is among native fish in the Baltic Sea
 Understanding the characteristics and conditions that make non-indigenous species (NIS) successful at establishing in recipient communities is a key in determining their potential impacts on native species, as well as to improve management actions such as prevention of future invasions. The round goby (Neogobius melanostomus) is one of the most widespread non-indigenous fish species in the Northern Hemisphere, including the coastal zones of the Baltic Sea. The impacts of round goby in the Baltic Sea are pronounced and multifaceted, yet our knowledge regarding the underlying assembly processes determining its establishment is limited. To overcome this knowledge gap, we applied a trait-based approach to assess the degree of niche overlap and functional (trait) similarity between round goby and native fish species in coastal areas from the Baltic Sea, based on the functional distinctiveness metric. Our results show that round goby is generally quite similar (or not dissimilar) to the native fish of the regional species pool, at least in terms of its overall trait composition. Conversely, round goby demonstrates pronounced differences compared to the native community in its display of parental care and territorial behaviour. Such differences in individual traits could play an important role in round goby’s invasion success in the Baltic Sea, including its interactions with native species (e.g. competition). Our results and their potential implications may be highly relevant for conservation and management if integrated within existing risk assessment tools for biological invasions in order to prioritise and enhance the effectiveness of preventative actions towards the expansion of round goby.

期刊介绍: NeoBiota is a peer-reviewed, open-access, rapid online journal launched to accelerate research on alien species and biological invasions: aquatic and terrestrial, animals, plants, fungi and micro-organisms. The journal NeoBiota is a continuation of the former NEOBIOTA publication series; for volumes 1-8 see http://www.oekosys.tu-berlin.de/menue/neobiota All articles are published immediately upon editorial approval. All published papers can be freely copied, downloaded, printed and distributed at no charge for the reader. Authors are thus encouraged to post the pdf files of published papers on their homepages or elsewhere to expedite distribution. There is no charge for color.
