AB For the first time, a comprehensive assessment of Mesophyllum species diversity and their distribution in Atlantic Europe and theMediterranean Sea is presented based on molecular (COI-5P, psbA) and morphological data. The distribution ranges wereredefined for the four species collected in this study: M. alternans, M. expansum, M. macroblastum and M. sphaericum.Mesophyllum sphaericum, which was previously known only from a single maerl bed in Galicia (NW Spain), is reported from theMediterranean Sea. The known range of M. expansum (Mediterranean and Macaronesia) was extended to the Atlantic IberianPeninsula. The occurrence of M. alternans was confirmed along the Atlantic French coast south to Algarve (southern Portugal).Mesophyllum lichenoides was only recorded from the Atlantic, whereas M. macroblastum appears to be restricted to theMediterranean Sea. A positive correlation was observed between maximum Sea Surface Temperature (SSTmax) and the depth atwhich M. expansum was collected, suggesting that this species may compensate for higher SST by growing in deeper habitatswhere the temperature is lower. The latter indicates that geographic shifts in the distribution of coastal species as a result of globalwarming can possibly be mitigated by changes in the depth profile at which these species occur. Mesophyllum expansum, animportant builder of Mediterranean coralligenous habitats, may be a good target species to assess its response to climate change.
