CEXS-UPF: A method for predicting biological invasions

News from CEXS-UPF

Along with habitat destruction and hunting, one of the most important causes of loss of biodiversity on our planet due to invasive species, favored in recent decades by globalization. The entry of exotic supposed competition with native species, which sometimes ends with the termination of some or many of these.

In a study published on September 16 in the journal Ecology Letters, in which there is involvement of Ricard Solé , ICREA researcher and head of the Laboratory of Complex Systems, Department of Experimental Sciences and Health (CEXS-UPF) it presents a new method for analyzing fish species that have entered the Red Sea to the Mediterranean through the Suez Canal. The method compares the morphology of the exotic species with native species and makes a prediction of its success.

Researchers have found a relationship between niche and potential invasion, an aspect that the same Charles Darwin (1809-1889) had advanced in his book The Origin of Species (1859), which now allows predict the chances of success which has an introduced species. Ricard Solé explains that the development of this method has been possible because for the first time joined two well-established areas but so far separated: morfoespais theory and the theory of biological invasions. "This is one of the great innovations of the study and allowing us to confirm Darwin's original idea," said Sole.
