Not all individuals of the same species are identical: There is a marked variability within the same population, and sometimes, these morphological differences are translated into a different behavior. A study by the UB shows that fishing alters resource distribution and therefore the behavior of two typologies of the same fish species, Labrus bergylta. These results, published in the journal Marine Ecology Progress Series, show that fishing hardens the understanding of how the features of species have evolved in exploited ecosystems, since it has an impact on how they act and feed from animals. Also, results ratify the importance of marine reservoirs to understand the original behavior of these ecosystems before human intervention.
