A big number of Red Sea species have entered the Mediterranean since opening Suez Canal. Some them quickly establish local populations and increase their abundance, forming a potential threat for biodiversity fisheries. Here, we use habitat modeling tools to study expansion three alien, demersal fish that basin at different times: Pterois miles, Siganus luridus rivulatus. Georeferenced occurren...

One of the most degraded states of the Mediterranean rocky infralittoral ecosystem is a barren composed solely of bare rock and patches of crustose coralline algae. Barrens are typically created by the grazing action of large sea urchin populations. In 2008 we observed extensive areas almost devoid of erect algae, where sea urchins were rare, on the Mediterranean coast of Turkey. To determine t...

Abstract Marine organisms that enter the Mediterranean from Red Sea via Suez Canal are known as Lessepsian bioinvaders. In general, genetic studies of fishes have shown little structure between and populations. Yet notable exceptions suggest importance life-history factors may influence patterns spatial variation. this study, by sampling two invasive with different life histories (the rabbitfis...
