Invasive Marine Algae: An Ecological Perspective.

The significance of marine algal invasion is undisputed in the global context; however, this topic has not received as much attention as it deserves. Although substantial evidence supports the fact of marine algal introduction and invasion, the underlying ecological principles need more attention to better explain such invasions. Marine algal invasions transcend national boundaries, so the problem must be considered an international problem. Commercial exploitation of invasive marine algae (and under this category we include deliberate introductions) should be undertaken, if at all, with great care and with a full understanding of all aspects of the biology and ecological consequences of the new exotic species. The aim of this article is to define algal invaders from a marine ecosystem standpoint and to discuss the different vectors, their dispersal patterns, and mechanisms of their dominance in their naturalized or introduced range.
