Colonization of new habitats through dispersal of phytoplankton cysts might be limited, if resident populations outcompete invaders during germination. We reciprocally transferred (Raphidophyceae) cysts from three lakes into native and foreign waters originating from the respective habitats. Germination rate and germling growth were impacted by water origin, but there was no preference for native water. 's ability to germinate in different conditions might explain its expansion in northern Europe.
如果浮游植物孢囊在萌发过程中，当地种群胜过入侵者，那么通过浮游植物孢囊扩散实现的新栖息地定殖可能会受到限制。我们将来自三个湖泊的（裸藻门）孢囊相互转移到各自栖息地的本地和外地水域中。萌发率和幼体生长受到水源的影响，但对本地水没有偏好。其在不同条件下的萌发能力可能解释了它在北欧的扩张。
