WEBThe first reports of non-indigenous Botrylloides spp. in the English Channel were made after RAS in 2004 (Arenas et al., 2006). A single species, B. violaceus, was reported, recognized by its single-colored colonies and large and morphologically distinctive brooded larvae. Colonies of B. violaceus could occur

WEBMolecular tools have been extensively used in recent decades to examine biological invasion processes, and are increasingly being adopted as efficient tools to support non-indigenous species surveys, notably through barcoding approaches, i.e., the use of a reference sequence specific to a given species to validate its identification. The …
