Cryptic invasion in Southern Europe: The case of Ferrissia fragilis (Pulmonata: Ancylidae) Mediterranean populations
2011
Four populations of the North American ancylid gastropod Ferrissia fragilis have been found in Southern Italy, thus expanding the known Eurasian distribution range of this invasive gastropod to the Mediterranean area. Both mitochondrial markers used for the molecular identification of the sampled specimens (16S and COI) showed a modest to absent haplotypic diversity in the studied Ferrissia populations from Europe and Asia, and their perfect identity with some of the haplotypes observed in North American F. fragilis populations. In the light of the scarce molecular diversity observed in the whole Palaearctic area and of the growing evidences for the ongoing spreading of the species in Europ…
First record of the tadpole shrimp triops cancriformis (Branchiopoda, Notostraca) in Cyprus
2014
The presence of the large branchiopod Triops cancriformis (Bosc, 1801-1802) in Cyprus is reported for the first time. Triops cancriformis individuals were observed in the large temporary wetland of Paralimni Lake (Famagusta District, Cyprus) during the wet periods of 2013 and 2014. This finding extends the current knowledge of the species distribution in the eastern Mediterranean area, and stresses the ecological and conservation value of the unique habitat of Paralimni Lake. In addition, it highlights the need for carrying on further studies on the fauna of temporary pond habitats in Cyprus, and for better conservation management strategies for such EU priority habitats.
First record of the North American cryptic invader Ferrissia fragilis (Tryon, 1863) (Mollusca: Gastropoda: Planorbidae) in the Middle East
2014
Some gastropod specimens belonging to the planorbid genus Ferrissia were recently collected in Lebanon and in Iraq, where the autochthonous species Ferrissia clessiniana (Jickeli, 1882) is supposed to occur. The molecular identification of collected specimens proved that they belong to the allochthonous species Ferrissia fragilis (Tryon, 1863), the protagonist of a dramatic cryptic invasion which is of interest to the whole of Eurasia. These findings cast further doubts on the actual existence of autochthonous Ferrissia species in the Palaearctic. The need for a molecular characterisation of the topotypical population of F. clessiniana, and for a revision of the Palaearctic Ferrissia specie…
Molecular Identification and Biochemical Characterization of Novel Marine Yeast Strains with Potential Application in Industrial Biotechnology
2022
Cell-based agriculture is an emerging and attractive alternative to produce various food ingredients. In this study, five strains of marine yeast were isolated, molecularly identified and biochemically characterized. Molecular identification was realized by sequencing the DNA ITS1 and D1/D2 region, and sequences were registered in GenBank as Yarrowia lipolytica YlTun15, Rhodotorula mucilaginosa RmTun15, Candida tenuis CtTun15, Debaryomyces hansenii DhTun2015 and Trichosporon asahii TaTun15. Yeasts showed protein content varying from 26% (YlTun15) to 40% (CtTun15 and DhTun2015), and essential amino acids ranging from 38.1 to 64.4% of the total AAs (CtTun15-YlTun15, respectively).
