摘要

外来鱼类物种的引入和传播对淡水中的本地生物群落和生态系统功能构成了重大威胁。黑头鹎是欧洲水域最成功的入侵者之一,对本地生物群落和生态系统造成了多种有害影响。在这项研究中,我们利用稳定同位素分析比较了匈牙利巴拉顿湖中入侵的黑头鹎与两种本地鱼类(鳊鱼和欧洲鲈鱼)的体型、季节性食性、营养位置、同位素生态位大小和生态位重叠情况。我们发现,黑头鹎的食性特点是食虫-食鱼,鱼类消耗率较高。入侵的黑头鹎捕食鱼类的比例随着体型的增大而增加,而鱼类消耗量则没有季节性差异。与我们的假设相反,几乎没有发现黑头鹎与本地鱼类之间存在实际的摄食竞争。我们的研究结果表明,所研究的物种以不同的比例吸收不同的能量资源,导致它们之间存在大量的生态位分配。我们的结论是,黑头鱼可能主要通过捕食对本地小型鱼类构成威胁,并建议采取紧急管理措施(如有选择性地移除该物种),以尽量减少其对本地群落的不利影响。

Stable isotope analysis reveals diet niche partitioning between native species and the invasive black bullhead (Ameiurus melas Rafinesque, 1820)
The introduction and spread of alien fish species pose a major threat to native communities and ecosystem functioning in freshwaters. Black bullhead is one of the most successful invaders in European waters with several detrimental effects on native biota and ecosystems. In this study, we used stable isotope analysis to compare the body size and season-dependent diet, trophic position, isotopic niche size, and niche overlap of the invasive black bullhead with two native fish species (roach and European perch) in Lake Balaton, Hungary. We found that black bullhead could be characterized by invertivore-piscivorous feeding habit with a high rate of fish consumption. The rate of fish predation by invasive black bullhead increased with body size, while no seasonal differences were observed in fish consumption. Contrary to our hypothesis, little evidence of actual feeding competition was found between black bullhead and native fishes. Our results suggest that the studied species assimilate distinct energy resources in different proportions leading to a substantial amount of niche partitioning among them. We conclude that black bullhead may represent a threat for native, small-sized fishes primarily through predation and recommend urgent management actions (e.g. selective removal of the species) to minimize its adverse impacts on native communities.
