Siguiendo el ejemplo fenicio: colonización del Mediterráneo occidental por Spirobranchus cf. tetraceros (Annelida: Serpulidae)
2020
A newly established population of the fouling polychaete Spirobranchus cf. tetraceros is reported from the western Mediterranean (Valencia Port). Despite previous intensive surveys, this is the first record for the taxon in the Iberian Peninsula. Molecular analyses revealed that S. cf. tetraceros from Valencia are genetically identical to specimens from Heraklion, Crete, but different from those collected in the Red Sea and S. tetraceros sensu stricto from the type locality in Australia. Mediterranean and Red Sea S. cf. tetraceros form a well-supported monophyletic clade but are clearly distinct from New South Wales specimens of S. tetraceros. Our new molecular evidence supports the hypothe…
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…
The Inland Water Copepod Fauna of a Traditional Rural Landscape in a Mediterranean Island (Crustacea, Copepoda)
2022
Although the Mediterranean area is a well-known hotspot of biological diversity, the crustacean assemblages inhabiting inland waters of the Mediterranean islands are to date unevenly known, and detailed information is missing for most taxa and areas. In the frame of this paper, we provide a checklist and a characterization of the copepod fauna of the lentic water bodies occurring in a traditional rural landscape of Sicily, where the co-existence of agriculture, woodlands, and pastoral activities lead to the presence of a wide range of different aquatic habitats. Overall, 22 copepod species belonging to the orders Calanoida, Cyclopoida, and Harpacticoida have been found in the 92 surveyed si…
