| Impact Description | It was observed in this study that Caulerpa prolifera colonized unvegetated sediment in Ria Formosa lagoon, Portugal outcompeting sea grasses. This potentially reduced the abundance of tanaids, the food source for two endangered seahorse species Hippocampus hippocampus and Hippocampus guttulatus and contributed to their decline in the area. |
