在过去几十年里，全球航运的强度急剧增加，各大洲之间的物种交换也同样加剧。船舶压载水被认为在这一过程中发挥着重要作用。许多较大的海港已成为侵略的桥头堡。利用生态位模型研究了北美端足类钩虾的潜在入侵范围和高入侵风险港口。62个G.在其原产地（北美）和34个环境数据集的tigrinus。利用扩散距离数据，通过生态位模型分析了该虫的入侵潜力。提格里诺斯。根据模拟结果，结合世界主要航道的盐度，分析了大型港口的入侵风险。G.虎尾虎在不列颠群岛和西欧其他地区的分布范围迅速扩大。现在它正在入侵波罗的海周边国家。在世界范围内，它具有巨大的潜在入侵范围。主要大洋航线沿着的许多大型港口都有较高的入侵风险，其中上海、布宜诺斯艾利斯和蒙得维的亚的港口入侵风险最高。G.虎斑蝶可能通过航运而遍布世界各地，而且这种可能性正在增加。应特别强调防止人为传播。端口可以是G.虎斑蝶入侵。这项研究可以识别高入侵风险的港口，特别是那些有引入北美物种风险的港口。更重要的是，应定期监测大型港口的水域，以寻找可能暂时或永久存活的外来水生生物。
While the intensity of global shipping has increased dramatically over the last decades, species exchange between continents has likewise intensified. Ballast water of ships is recognized playing a major role in this process. Many of the larger sea ports have become bridgeheads for invasions. Ecological niche modeling is used to investigate the potential invasive range and high invasive risk ports of the North American amphipod Gammarus tigrinus. Sixty-two occurrences of G. tigrinus in its native range (North America) and 34 environmental data sets were compiled. Data on dispersal distances were used via ecological niche modeling to analyze the invasive potential of G. tigrinus. The invasive risk of large ports was analyzed according to modeling result, as well as their salinity in the main oceanic routes of the world. G. tigrinus had a rapid range extension on the British Isles and in the rest of Western Europe. Now it is invading the countries surrounding the Baltic Sea. Worldwide it has a vast potential invasive range. It has a high invasive risk for many large ports along the main oceanic routes, among which the ports of Shanghai, Buenos Aires and Montevideo have the highest invasive risk. G. tigrinus may become cosmopolitan through shipping, and this possibility is increasing. Particular emphasis should be placed on preventing human-mediated dispersal. Ports may be the first places G. tigrinus invades. This study can identify high invasive risk ports, especially those at risk of introduced North America species. More importantly, the water of large ports should be monitored regularly for exotic aquatic organisms that may survive temporarily or permanently.
