A paper published in the journal PLoS ONE, whose first author is lecturer Bernat Hereu, from the Department of Ecology of the UB, shows the main results of twenty years of scientific studies monitoring sea urchins (Paracentrotus lividus and Arbacia lixula) in the Medes Islands. These two species are the most common sea urchins in the Mediterranean area. The work gives insight into which processes regulate long-term populations of sea urchins, and it includes extraordinary episodes such as the violent storm that hit the Catalan coast on 26 December 2008, which caused the disappearance of around 80% of the population of sea urchins in the archipelago of the Medes and the Montgrí coast.
