Ploidy variants can be utilized to increase yield, introduce sterility, and modify specific traits with an economic impact. Despite economic importance of Saccharina species, their nuclear DNA content in different cell types and life stages remain unclear. The present research was initiated to determine the nuclear DNA content and intraindividual v...
Seaweeds contain a wide range of secondary metabolites which serve multiple functions, including chemical and ecological mediation with microorganisms. Moreover, owing to their diverse bioactivity, including their antibiotic properties, they show potential for human use. Nonetheless, the chemical ecology of seaweeds is not equally understood across...
Here we report for the first time the presence of Dictyota cyanoloma in southern California. Dictyota cyanoloma is conspicuous in harbors and bays by its distinctive bright blue‐iridescent margins. This species was originally described from Europe but subsequent studies have revealed that it represented an introduction from Australia. The current d...
Nuclear DNA content of marine macroalgae is known for only about a 3% of the globally known taxa, and so far, the only available data concerning marine Antarctic macroalgae refer to the Phaeophyceae Ascoseira mirabilis and Desmarestia antarctica. As these data can be useful for species delimitation when combined with other taxonomical information,...
The seaweed diversity of the Mediterranean is still not completely known, especially in some areas of its African coasts. As an effort to complete a more detailed catalogue to fill such gap, an updated checklist of seaweeds from Algeria, based on updated literature records, is developed using as starting point the checklist of Perret-Boudouresque a...
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...
Deception Island is an active volcano located at the southern end of the South Shetland Archipelago, in the Antarctic Ocean. After the last eruption in 1970, benthic recolonization took place within the bay, with echinoderms being the dominant epifauna (e.g., the ophiuroid Ophionotus victoriae, the echinoid Sterechinus neumayeri and the sea star Od...
Genetic affiliation, nuclear DNA content, and gamete functioning were examined in small salt marsh Fucus from three localities in western Ireland. Individuals with small and dioecious receptacles were found at all localities, but production of germlings was only evident at Locality 1. Here, the Fucus vegetation formed a morphological cline from F....
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...
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...
Fucus baillouviana S.G. Gmel. (l.c.) is a validly published name of uncertain nomenclatural application, as explained below. The associated taxon is usually treated as the red alga Dasya baillouviana (S.G. Gmel.) Mont. (in Webb & Berthelot, Hist. Nat. Iles Canaries 3(2,4): 165. Jan 1841). The designated lectotype, an illustration published in 1750...

Caulerpa species are marine green algae, which often act as invasive species with rapid clonal proliferation when growing outside their native biogeographical borders. Despite many publications on the genetics and ecology of Caulerpa species, their life history and ploidy levels are still to be resolved and are the subject of large controversy. Whi...
The main predators of Antarctic benthic organisms are vagile invertebrates, including dense amphipod populations. Marked seasonalities of food availability drive consumers to develop opportunistic behaviors, which favors the evolution of defensive chemistry in potential prey. We used the circumpolar omnivorous amphipod Cheirimedon femoratus and a n...

Rhodonema was described as a new monotypic genus of ‘Siphonigonatae’ by Martens in 1824, to include R. elegans. The name was synonymised soon to Dasya, a genus proposed by C. Agardh also in 1824, again for a sole species D. pedicellata. It was later widened by C. Agardh himself (Sp. Alg. 2(1): 116–123. 1828) to group seven species, some of which ar...
