“…Ulva fasciata Delile [considered to be a synonym of U. lactuca Linnaeus (O'Kelly et al, 2010)] typically has a long strap-shaped thallus (Phillips, 1988), but Mshigeni & Kajumulo (1979) showed that the thalli of this species were small, rosette-like and irregularly lobed in wave-exposed habitats. Ulva pertusa Kjellman [considered to be a synonym of U. australis Areschoug (Couceiro et al, 2011;Kirkendale et al, 2013)] typically has a large, expanding thallus with holes (Kjellman 1897). Kang & Lee (2002) reported that U. pertusa and U.…”

“…Currently, U. pertusa is regarded as a taxonomic synonym of Ulva australis , based on the nuclear‐encoded ITS1 and the plastid‐encoded rbc L markers and morphological data (Couceiro et al. , Guiry and Guiry ). However, the type specimen for both taxa has yet to be sequenced, and U. pertusa is still a commonly used taxonomic name.…”

To further understand the trends in the evolution of mitochondrial genomes (mitogenomes or mtDNAs) in the Ulvophyceae, the mitogenomes of two separate thalli of Ulva pertusa were sequenced. Two U. pertusa mitogenomes (Up1 and Up2) were 69,333 bp and 64,602 bp in length. These mitogenomes shared two ribosomal RNAs (rRNAs), 28 transfer RNAs (tRNAs), 29 protein-coding genes, and 12 open reading frames. The 4.7 kb difference in size was attributed to variation in intron content and tandem repeat regions. A total of six introns were present in the smaller U. pertusa mtDNA (Up2), while the larger mtDNA (Up1) had eight. The larger mtDNA had two additional group II introns in two genes (cox1 and cox2) and tandem duplication mutations in noncoding regions. Our results showed the first case of intraspecific variation in chlorophytan mitogenomes and provided further genomic data for the undersampled Ulvophyceae.

“…The probable synonymy between Ulva australis and Ulva pertusa is consistent with their morphological similarities and it was suggested that Ulva australis is the valid name for the non-native green macroalga (COUCEIRO et al, 2011 Sci., 12/2, 2011, 509-514 511 Notes: Chrysallida fischeri was first recorded from the Adriatic Sea (MAZZIOTTI et al, 2002) and then described as Turbonilla flaianoi (MAZZIOTTI et al, 2005).…”

The state-of-art on alien species in the Mediterranean Sea is presented, making distinctions among the four subregions defined in the EU Marine Strategy Framework Directive: (i) the Western Mediterranean Sea (WMED); (ii) the Central Mediterranean Sea (CMED); (iii) the Adriatic Sea (ADRIA); and (iv) the Eastern Mediterranean Sea (EMED). The updated checklist (December 2010) of marine alien species within each subregion, along with their acclimatization status and origin, is provided. A total of 955 alien species is known in the Mediterranean, the vast majority of them having being introduced in the EMED (718), less in the WMED (328) and CMED (267) and least in the Adriatic (171). Of these, 535 species (56%) are established in at least one area.Despite the collective effort of experts who attempted in this work, the number of introduced species remains probably underestimated. Excluding microalgae, for which knowledge is still insufficient, aliens have increased the total species richness of the Mediterranean Sea by 5.9%. This figure should not be directly read as an indication of higher biodiversity, as spreading of so many aliens within the basin is possibly causing biotic homogenization. Thermophilic species, i.e. Indo-Pacific, Indian Ocean, Red Sea, Tropical Atlantic, Tropical Pacific, and circum(sub)tropical, account for 88.4% of the introduced species in the EMED, 72.8% in the CMED, 59.3% in the WMED and 56.1% in the Adriatic. Cold water species, i.e. circumboreal, N Atlantic, and N Pacific, make up a small percentage of the introduced species, ranging between 4.2% and 21.6% and being more numerous in the Adriatic and less so in the EMED.Species that are classified as invasive or potentially invasive are 134 in the whole of the Mediterranean: 108 are present in the EMED, 76 in the CMED, 53 in the Adriatic and 64 in the WMED. The WMED hosts most invasive macrophytes, whereas the EMED has the lion’s share in polychaetes, crustaceans, molluscs and fish.
