摘要

helminthorrhiza Ludwigia的引种在此证实，H.Hara (onagracae)通过未知的途径进入古巴，以及其成功归化和40多年来占领地区的持续增加。讨论了其侨民的数量和质量对于在新领土上扩散和建立的重要性，以及分散剂的有效性。确定了引入该物种的负面影响(水族馆管理困难、沉积、阻挡光线进入、氧气交换减少和本地物种的迁移)和积极影响(动物群的食物和减少污染的细菌住房)。关于该物种可能扩展到该国新的淡水水库的警告已发布。

Expansión de Ludwigia helminthorrhiza (Onagraceae) en Cuba

The introduction of Ludwigia helminthorrhiza (Mart.) H.Hara (Onagraceae) into Cuba, by an unknown route, as well as its successful naturalization and sustained increase in its area of occupation for over 40 years is here confirmed. The importance of the quantity and quality of its diasporas for dispersal and establishment in new territories is discussed, as well as the effectiveness of the dispersal agents. The negative impacts (difficulties in the management of aquariums, sedimentation, blocking of light entry, reduction of oxygen exchange, and displacement of native species) and the positive impacts (food for fauna and bacteria housing that reduce pollution) of the introduction of this species were identified. An alert is issued regarding the possible expansion of this species to new freshwater reservoirs in the country.
