Genetics reveal the identity and origin of the lionfish invasion in the Mediterranean Sea

Abstract Following aquarium releases, invasive lionfishes have colonized large areas of the Caribbean and western Atlantic, resulting in an immense ecological damage. The early stages of that invasion are poorly known. Indeed, a lag of time between the introduction and detection often preclude genet...
