Grazing snails rule the waves
Date:5/31/2012

Coral reefs and seashores largely look the way they do because large fish and urchins eat most of the seaweed that might otherwise cover them, but a major new study has found that the greatest impact of all comes from an unexpected quarter small marine snails.

The study published in the journal Ecology Letters is the largest of its kind ever undertaken into the ecological impacts of marine grazing animals: it was led by Associate Professor Alistair Poore, of the UNSW Evolution & Ecology Research Centre, who worked with an international team of 10 researchers.

It found that, on average, marine herbivores remove almost 70% of the plant material growing on the sea floor an effect far greater than grazing animals have on land plants.

"We found that across the globe marine herbivores profoundly reduce the abundance of marine plants, with the strongest effects in rocky seashores," says Poore.

"Icons like the Great Barrier Reef would look very different otherwise: the corals and rocks are usually free of seaweed, but that's only because animals eat all the plants as soon as they grow.

"Big animals such as fish and urchins have major impacts on reefs and kelp forests but what may surprise many people is that we found that the strongest impacts of all were snails controlling seaweeds on rocky shores."

The study team analysed results from over 600 experiments, conducted over the past 40 years across the planet, where ecologists have experimentally removed herbivores to understand their importance in structuring marine habitats.

Manipulating animals in their natural habitats is the most powerful technique to understand how ecological interactions work, they note.

"When these grazing animals are removed, the seaweeds quickly start to dominate," notes Poore. "One of the exercises we give our students to illustrate this is to visit a rocky shore at Sydney's Maroubra Beach and remove all the snails fr
