Molecular and morphological characterization of Melanothamnus testudinis sp. nov. (Rhodophyta, Rhodomelaceae) and its distinction from Polysiphonia carettia.
No full textThe association between epizoic algae and animals is well known, and turtles are among the animals that most commonly host epibiont communities. 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

Sponge-associated cyanobacterial diversity and activity: evidences from the northern Ionian Sea
No full textA new cryptic species of the unicellular red algal genus Dixoniella (Rhodellophyceae, Proteorhodophytina): Dixoniella giordanoi.
No full textDuring samplings aimed at isolating microalgal strains, a coccoid greyish-green alga was collected along the North Adriatic coasts (Mediterranean Sea, Italy) and grown in culture. The microalgal strain (named strain B1A) was then subjected to an integrative taxonomy approach in order to correctly identify it. Morphological and ultrastructural observations and phycobiliprotein content analysis were carried out, as well as molecular analyses based on the 18S rRNA, rbcL, psbA and plastid-encoded 23S rRNA genes. Phylogenetic placement and ultrastructural observations clearly indicated that strain B1A is a member of the red microalgal genus Dixoniella (Rhodellophyceae, Proteorhodophytina) and is distinct from the only species so far described for this taxon. Therefore, a new species was described to encompass the isolate from the North Adriatic Sea and another isolate from Japan (MF-G2), which was phylogenetically related to strain B1A: Dixoniella giordanoi sp. nov

No full textMolecular analyses were carried out on different Ceramium specimens collected in the North Adriatic Sea in order to survey the biodiversity of this red algal genus in the area
Cyanobacterium of the family Pseudanabaenaceae (Oscillatoriales, Cyanophyta), genus Protolyngbya, species Protolyngbya sp. strain ITD-02
No full textIt is herein described the identification and characterizationof a new strain of cyanobacterium belonging to the family Pseudanabaenaceae (Oscillatoriales, Cyanophyta), genus Protolyngbya, designated strain ITD-01, found on the surface of the Ischia thermal muds. This cyanobacterium is found to be particularly rich in C-phycocyanin
