Molecular approaches have proven efficient to identify cryptic lineages within single taxonomic entities. Sometimes these cryptic lineages maybe previously unreported or unknown invasive taxa. The genetic structure of the marine gastropod Stramonita haemastoma has been examined in the Western Mediterranean and North-Eastern Atlantic populations with mtDNA COI sequences and three newly developed...

One of the most debated problems in conservation biology is the use of indicator (surrogate) taxa to predict spatial patterns in other taxa. Cross-taxon congruence in species richness patterns is of paramount importance at regional scales to disclose areas of high conservation value that are significant in a broader biogeographical context but yet placed in the finer, more practical, political ...

Temnothorax antigoni (Forel, 1911) is redescribed basing on a new material from southwestern Turkey (Antalya province), Lesbos and Rhodes (Greece, Aegean and Dodecanese islands). The gyne of this species is described for the first time. Temnothorax curtisetosus, a new species of social parasite collected in a nest of Temnothorax antigoni, is described. Colour photos of both taxa are given. A ke...

The eastern Mediterranean is a hotspot of biological invasions. Numerous species of Indo-pacific origin have colonized the Mediterranean in recent times, including tropical symbiont-bearing foraminifera. Among these is the species Pararotalia calcariformata. Unlike other invasive foraminifera, this species was discovered only two decades ago and is restricted to the eastern Mediterranean coast....

Sobel and Randle (2009) challenge several methodological choices in the comparative study of the evolution of reproductive isolation in Mediterranean deceptive orchids of Scopece et al. (2007) including the species concept used and the selection of taxa, together with the perceived comparison of clades of different ages. They further criticize that pollinator information was taken from the lite...

BACKGROUND Wild vegetables in the Mediterranean Basin are still often consumed as a part of the diet and, in particular, there is a great tradition regarding their use in Sicily. In this study, an ethnobotanical field investigation was carried out to (a) identify the wild native taxa traditionally gathered and consumed as vegetables in Sicily, comparing the collected ethnobotanical data with th...

An annotated species list is provided on the basis of seven sampling surveys of decapod crustaceans carried out on various supra-, medioand infralittoral substrates (sandy bottoms, rocky shores, seagrass beds of Posidonia oceanica) at four locations on the Adriatic Sea: Rovinj (in 1968), Slanik Bay (in 2001) and Pula (in 2004, 2005) on the Istrian Peninsula and the island of Šipan (in 2001, 200...

BACKGROUND AND AIMS Two Phragmites australis taxa are recognized in Europe: P. australis ssp. altissimus, also known as Phragmites isiaca, in the Mediterranean region and P. australis in the temperate region. Another taxonomic group in the Mediterranean is Phragmites frutescens. European genotypes are diverse genetically, cytologically and morphologically, and are related to African, Asiatic an...

Penalized likelihood analysis of previously published chloroplast DNA (cpDNA) ndhF sequences suggests that the central-southern Andean genus Chaetanthera diverged ca. 16.5 million years (my) ago, well before the uplift of the Andes to their present heights. Penalized likelihood analysis based on new nuclear ribosomal DNA (rDNA) internal transcribed spacer (ITS) sequences indicates that the most...
