Warming and acidification benefits invasive marine organisms

What is it about?

We have found that jellyfish and invasive algae thrive as carbon dioxide levels increase and a review of the literature provides ample evidence that invasive species, jellyfish and toxic algae may benefit form the warming and acidification of coastal waters.

Why is it important?

The spread of stinging jellyfish, harmful algal blooms and invasive alien species has major economic implications - harming aquaculture, fisheries and tourism

As this paper was going to press, a PhD student of mine (Demetris Kletou) has started seeing the spread of lionfish in the Mediterranean - the same species that has run riot in Caribbean marine ecosystems. We are seeing tropicalization of temperate regions, coupled with the adverse effects of overfishing, habitat destruction and pollutants such as CO2.
