“…The presence of three genetically differentiated lineages within the Alyssum diffusum complex in the present study, inhabiting Gargano, the central Apennines (Abruzzo and Umbria), and the southern Apennines/northern Calabrian Arc, coincides very well with the patterns in other plant genera and reiterates the evolutionary importance of these regions. We assume that these three intraspecific lineages represent the descendants of separate refugial populations, in congruence with the “refugia‐within‐refugia” hypothesis, favored by several groups of organisms, including plants (Magri et al, 2006; Ansell et al, 2008), mollusks (Fiorentino et al, 2010), amphibians (Canestrelli et al, 2006, 2007, 2008; Canestrelli and Nascetti, 2008), reptiles (Böhme et al, 2007), and mammals (Ruedi et al, 2008; Vega et al, 2010).…”

We provide evidence for the presence of Mediterranean refugia for the studied Alyssum montanum-A. repens complex located in central and southern Italy, which, however, did not contribute to the postglacial colonization of Central Europe. Past extinctions, genetic bottlenecks, and recent expansion were inferred in Central Europe, while long-term accumulation of diversity as well as polyploidization occurred in the Apennines.

Genetic structure in theGenista ephedroidescomplex (Fabaceae) and implications for its present distribution

However, although genetic diversity within populations was low [(hS = 0.132 (± 0.056)], a high level of total plastid DNA diversity [hT = 0.866 (± 0.042)] was detected, and analysis of molecular variance indicated that variation is almost exclusively expressed among populations (95.25%). The plastid microsatellites identify two groups of taxa, one including Sardinian taxa and populations of G. tyrrhena subsp. pontiana and the other including two subgroups, one of which includes Sicilian/Aeolian elements and the other with G. numidica/G. cilentina and G. dorycnifolia. Results allow us to consider G. cilentina as originating by recent anthropogenic dispersal and G. tyrrhena subsp. pontiana as a possible stabilized hybrid between local plants and members of the Sardinian group contributing the maternal lineage. The evolutionary history of the group possibly results from the effects of ancient events fostering geodispersal and range contraction, followed by more recent long-range dispersal or geodispersion over Pleistocenic land bridges.

“…Trans‐Adriatic dispersal was more likely during the Pleistocene across the dried northern Adriatic sea floor or the Otranto strait, which was probably narrowed to as little as 20 km during glacial phases (Jesse et al ., ; Çıplak, Heller & Willemse, ). Unfortunately, dating of the colonization from sequence divergence is not possible; the notorious lack of internal calibration points within Helicidae prevents meaningful use of a molecular clock (Fiorentino et al ., ; Kotsakiozi et al ., ). However, while crossing of the Adriatic basin during the period of low sea recession seems most likely, chance long‐range dispersal across the sea cannot be completely ruled out.…”

ResurrectingHelix straminea, a forgotten escargot with trans-Adriatic distribution: first insights into the genetic variation within the genusHelix(Gastropoda: Pulmonata)

Helix is a genus of large Western Palaearctic land snails, particularly diverse in the Mediterranean region. Despite the large size and attractiveness of its members, it has an unsettled taxonomy, and no data are available on its intrageneric phylogenetic relationships. One of the problematic Helix taxa is the widely distributed, economically important, and conchologically very variable H. lucorum. Two distinct forms may be encountered under this name in the Apennine Peninsula: a typical one in the north, and a form originally described as Helix straminea in central and southern Italy. To evaluate the status of H. straminea and its relationships to Italian and Balkan Helix fauna, we combined shell morphology, geometric morphometrics, and phylogenetic analysis based on two mitochondrial genes. Distribution data were improved by drawing information from unambiguously identifiable photographs posted online. Based on our results, Helix straminea is redescribed as a separate species, and we find it to have a disjunctive trans-Adriatic range with closest relatives in the western Balkans. We provide insight into relationships and intraspecific variability within Helix, a first step towards a comprehensive revision of the genus. On the example of Italian Helix fauna, we demonstrate how understanding of snail zoogeography may change with improving taxonomy.
