摘要
气候变化和激烈的人类活动加剧了物种分布范围的变化。虽然外来入侵物种在全球范围内的快速传播有据可查,但人们对本地物种的传播现象却知之甚少。要解释物种在不断变化的世界中迅速扩散的问题,就必须了解它们的生态学、遗传多样性和栖息地限制。我们研究的目的是分析大型沼泽植物 Trapa natans s. l. 种群的生态要求和遗传多样性,Trapa natans s. l. 是北美的外来入侵物种,但原产于欧洲和亚洲。我们调查了其原生地(欧洲中部和东北部)的种群,在那里该物种被定义为稀有或灭绝物种。我们发现 T. natans 出现在欧洲东北部的水生栖息地,到目前为止,该物种一直被描述为灭绝物种。我们的环境研究结果表明,该物种对栖息地条件有广泛的耐受性,可生活在中度到高度营养丰富、低盐度和高盐度的水中。利用扩增片段长度多态性(AFLP)分析,我们发现种群内部的遗传变异性很高,而种群之间的差异相对有限。我们发现,一些种群具有高度多样性(可能是中欧的避难所),而另一些种群则具有同质性(新地点、商业重引入;欧洲东北部)。natans 在其原生地的保护状况应重新考虑,因为该物种近几十年来迅速扩散,可能对水生栖息地造成危害。结论是,扩张/入侵可以从小种群开始,但在有利条件下,这些种群会迅速扩散。引入物种(即使是本地物种)也应谨慎从事,因为无节制地引入新地点(如私人池塘)可能是扩散(本地栖息地)或入侵(非本地区域)的开始。
A wide range of abiotic habitat factors and genetic diversity facilitate expansion of Trapa natans within its native range
Climate change and intense human activity are exacerbating changes in species' ranges. While the rapid spread of invasive alien species is well documented worldwide, the phenomenon of the spread of native species is poorly understood. To explain the problem of rapidly spreading species in the changing world, it is necessary to understand their ecology, genetic diversity and habitat limitation. The aim of our study was to analyze the ecological requirements and genetic diversity in the population of the macrophyte Trapa natans s. l., an invasive alien species in North America but native in Europe and Asia. We investigated the populations in its native range (Central and Northeastern Europe), where the species is defined as rare or extinct. We found the occurrence of T. natans in Northeastern Europe aquatic habitats where, up to now, it was described as an extinct species. The results of our environmental studies showed that the species has a wide range of tolerance to habitat conditions and lives in medium to highly nutrient-rich water with low and high salinity. Using Amplified Fragment Length Polymorphism (AFLP) analysis, we revealed high genetic variability within populations with relatively limited differentiation between populations. We showed that some populations are highly diverse (possibly refugia; Central Europe) and others are homogeneous (new sites, commercial reintroduction; Northeastern Europe). Conservation status of T. natans in its native range should be reconsidered, as the species has spread rapidly in recent decades and could be detrimental to aquatic habitats. The conclusion is that expansion/invasion can start from small populations, but under favorable conditions these populations spread rapidly. The introduction of species (even native) should be done carefully, if at all, as uncontrolled introduction to new locations, e.g. private ponds, could be the start of dispersal (native habitats) or invasion (non-native area).
