To carry out this research, a monitoring activity was conducted through both scuba dives and snorkelling activities. Through this study, a total of 13 species (four belonging to Cystoseira, three to Ericaria, two to Gongolaria, and four to Sargassum) was observed. When comparing the present data with past studies, nine species were previously reported, ten taxa were not found in the present study, and four taxa were reported here for the first time in the Aeolian Archipelago. The alpha (local) diversity was higher in Vulcano than in Lipari. Moreover, the beta (turnover) diversity showed a different assemblage in species grouping between the two islands. Since some of the observed species are currently considered rare or in regression, their finding in the Aeolian Archipelago is of particular interest. Therefore, they s...

The initial use of only morphological characters was stepwise substituted by the use of both anatomical and reproductive characters that permitted to better characterize species. Infrageneric sudivisions proposed throughout the years are discussed as well as criteria that permitted to ascribe to the resurrected genus Osmundea Stackhouse

The most studied algal component of the epizoic communities found on turtles is represented by diatoms, while other algal taxa, like the Rhodophyta, are less investigated. During a survey started to study the epibionts associated with loggerhead turtles, Caretta caretta, cared for at the WWF Sea Turtle Rescue Center of Lampedusa Island (Sicily, Italy), specimens of Rhodomelaceae (Rhodophyta) were collected for taxonomic investigation. The resulting vegetative, reproductive, and molecular data of those specimens characterised the new species described here as Melanothamnus testudinis sp. nov. We also evaluated the holotype of Polysiphonia carettia Hollenberg, an epibiont of C. caretta reported from the Mediterranean Sea. This investigation confirmed the distinction of M. testudinis from P. carettia and suggested that previous Mediterranean and Canarian records of the latter species are probably M. testudinis.

This species, occurring also in the Atlantic, where it was recorded under other names, shows the following main features: axes compressed; epidermal cells elongate, with secondary pit connections; medullary cells showing abundant lenticular thickenings; tetrasporangia, in parallel arrangement, cut off from the mother cells abaxially; antheridial branches unbranched, inserted in depressions that do not show a row of axial cells at their base. The species is included in the subgenus Laurencia, section Planae. The new subgenus Saitoa (type species L. pinnatifida), including the section Pinnatijidae J. Agardh emend. Furnari et Serio, is proposed. It is characterized by lack of secondary pit connections between epidermal cells and by parallel arrangement of tetrasporangia.

Here, a particular habitat is formed on upper infralittoral rocky bottoms beaten by waves, with S. alveolata developing as veneer-like bioconstructions interspersed/covered with a dense macroalgal community including alien Caulerpa taxa and dominated by Ericaria giacconei. First insights about the development of this particular habitat, as well as observations on possible relationships between Sabellaria and the associated algae, are presented.

In this context, the present study aims to provide the first biological and ecological characterisation of this poorly known area, focusing on habitats and species of conservation concern. Surveys were carried through a remotely operated vehicle (ROV) and allowed the identification of 19 habitat types, mostly considered of priority interest by the SPA/BD Protocol of the Barcelona Convention. A total of 269 taxa were also identified, mostly Porifera, Cnidaria and Pisces, among which 115 species are of conservation concern according to the International Union for Conservation of Nature (IUCN) Red Lists, the Habitats Directive, the Bern Convention, the SPA/BD Protocol and CITES. ROV surveys allowed some interesting observations on poorly known species and habitats. Results underlined t...

Presented in this study are the results of an integrative approach using both morphology and molecular data (COI-5P + rbcL) to establish which taxon these specimens should be referred to. Molecular analyses show these specimens belong to Laurenciella, and strongly suggest they are within the species L. marilzae. Morphological examinations of these Mediterranean specimens were also detailed and found to support the conclusion that they belong to L. marilzae.
