Phylogeography of Dictyota fasciola and Dictyota mediterranea (Dictyotales, Phaeophyceae): unexpected patterns on the Atlantic-Mediterranean marine transition and taxonomic implications
Article

  • May 2019
The Atlantic-Mediterranean marine transition is a fascinating biogeographic region, but still very poorly studied from the point of view of seaweed phylogeography. Dictyota fasciola and D. mediterranea (Dictyotales, Phaeophyceae) are two currently recognized sister species that share a large part of their distribution along the Mediterranean Sea an...

  • Jan 2017
ABSTRACTDictyota cyanoloma has recently been described from the Mediterranean Sea and Macaronesia but doubt had arisen as to whether this species was truly native in Europe. The species is mainly found on non-natural substrata (harbour walls, marinas, boat hulls, etc.), strongly suggesting that it is an introduction. Molecular sequence information...

Phenological and molecular studies on the introduced seaweed Dictyota cyanoloma (Dictyotales, Phaeophyceae) along the Mediterranean coast of the Iberian Peninsula

  • Nov 2016
Dictyota cyanoloma, a distinctive brown algal species characterized by a blue-iridescent margin, was recently reported as an introduced species in the Mediterranean Sea (Steen et al., 2016) but little is known about its distribution dynamics, morphological plasticity and genetic structure. In the present integrative study, we evaluate its past and...

... This conclusion is in agreement with several recent investigations on other Mediterranean seaweeds, which have shown great genetic diversity and some striking cases of cryptic speciation (e.g. De Jode et al., 2019;Pezzolesi et al., 2019;Vitales et al., 2019). Taken together, these studies support the role of the Mediterranean as a hotspot of genetic diversity for marine organisms, a scenario supported by numerous phylogeographic investigations (Patarnello et al., 2007, and references therein;Pascual et al., 2017). ...

... Carlton (2009) named such species pseudo-indigenous. For example, Dictyota cyanoloma was described as a new species from the Mediterranean Sea and Macaronesia (Tronholm et al., 2010), but subsequent collecting efforts revealed that the species most likely represents a cryptic introduction (Aragay Soler et al., 2016;Steen et al., 2017;Tran et al., 2021). Similarly, Porphyra olivii described from Greece (Brodie et al., 2007a) turned out to be conspecific with Neopyropia koreana (Vergés et al., 2013;Yang et al., 2020), a species native to the Northwest Pacific. ...
