“…Our results altogether strongly support that Colchis and western Caucasus served as a glacial refugium for the freshwater crab, P. ibericum. Although some studies imply multiple, independent glacial forest refugia in these areas (Neiber & Hausdorf, 2015;Tarkhnishvili, Thorpe, & Arntzen, 2000), our results suggest a homogeneous and large refugium along the eastern Black Sea coast.…”

Refugia are critical for the maintenance of biodiversity during the periods of Quaternary climatic oscillations. The long‐term persistence of refugial populations in a large continuous refugium has resulted in a homogenous pattern of genetic structure among populations, while highly structured evolutionary lineages characterize the restriction of refugial populations to smaller subrefugia. These mechanisms have resulted in the identification of hot spots of biodiversity within putative glacial refugia. We studied phylogeography of Potamon ibericum (Brachyura: Potamidae) in the drainages of the western Caucasus biodiversity hot spot (i.e., Colchis and the Caucasus) to infer spatial genetic structure and potential refugia for a freshwater crab in this region. These areas have traditionally considered as a refugium due to the presence of Tertiary relict species. We integrated population genetic data and historical demographic analysis from cytochrome oxidase subunit I sequences and paleoclimatic data from species distribution modeling (SDM). The results revealed the lack of phylogeographic structure and provided evidence for demographic expansion. The SDM presented a rather homogenous and large refugium that extended from northeast Turkey to Colchis during the last glacial period. In contrast to these findings, previous phylogeographic study on P. ibericum of the eastern Caucasus biodiversity hot spot (i.e., Hyrcania) identified multiple independent refugia. By combining these results, we explain the significance of this important western Palearctic hot spot of biological diversity in shaping the geographic distribution of intraspecific genetic diversity in a freshwater taxon.

“…Nevertheless, the importance of phylogeographic patterns in the Near Eastern refugia is now becoming more well defined and appreciated.

“…The additional sequences from the nuclear ribosomal gene cluster partly overlap with the sequence from Neiber and Hausdorf (). For polymerase chain reaction (PCR) and amplicon clean‐up, slightly modified versions of the protocols described in Neiber and Hausdorf () were used for this study. Amplifications were performed in 25 μl volumes containing 2 μl 10× amplification buffer B (biolab products , Bebensee, Germany), 4 μl MgCl 2 (25 m m , biolab products ), 1 μl dNTP mix (5 m m each, biolab products ), 1 μl of each primer (10 μ m ), 0.2 μl Crystal Taq DNA polymerase (biolab products ), 1 μl template DNA and 14.8 μl ddH 2 O under the following reaction conditions: an initial denaturation step at 94°C for 2 min, 40 PCR cycles (94°C for 30 s, primer specific annealing temperature (see Table ) for 30 s, 72°C for 40 s) and a final extension step at 72°C for 5 min.…”

Increasing the number of molecular markers resolves the phylogenetic relationship of ‘Cepaea ’ vindobonensis (Pfeiffer 1828) with Caucasotachea Boettger 1909 (Gastropoda: Pulmonata: Helicidae)

‘Cepaea’ vindobonensis has been shown to be closely related to Caucasotachea in recent molecular studies. The phylogenetic relationships within this clade and especially the phylogenetic position of ‘Cepaea’ vindobonensis were, however, not well resolved. Our phylogenetic analyses on the basis of an increased number of molecular genetic loci from the mitochondrial and nuclear genomes unambiguously demonstrate that ‘Cepaea’ vindobonensis represents the sister group of the Caucasotachea taxa, with C. leucoranea from the Caspian region of Azerbaijan and Iran being the sister species of the remaining Caucasian and eastern Pontic Caucasotachea species. We argue for the inclusion of ‘Cepaea’ vindobonensis in Caucasotachea rather than for a re‐erection of a monotypic genus Austrotachea for the species because of the overall low degree of morphological differentiation and the low number of species in the group.

“…Actually, such losses have been documented in various lineages of the Helicoidea (Hirano, Kameda, Kimura, & Chiba, ; Neiber & Hausdorf, ; Neiber, Razkin, & Hausdorf, ; Wade, Hudelot, Davison, Naggs, & Mordan, ). Neiber and Hausdorf () hypothesized that natural selection might counteract sexual selection, for example, when it results in injuries or an increased infection risk of the dart recipient or a prolongation of the mating because of the delayed intake of the spermatophore, during which the individuals are under risk of desiccation or predation. However, the selective pressures and the circumstances that result in the loss of genital characters under strong sexual selection like the dart sac can hardly be studied experimentally because of the lack of intraspecific variation.…”

During mating the dart apparatus of the land snail group Helicoidea transfers an allohormone that increases paternity success. Thus, this organ is under sexual selection. Despite this selective advantage, the dart sac has independently been lost in many lineages in the Helicoidea, presumably because natural selection counteracts sexual selection. However, the selective pressures that result in the loss of the organ have not been examined experimentally because most species show no variation in the presence or absence of the dart sac. Using nuclear multilocus data and mitochondrial sequences, we show that a so far misidentified morph of the genus Monacha without appendicula, a homologue of the dart sac, is conspecific with M. kuznetsovi with appendicula. This is only the second case of polymorphy with regard to the presence or absence of the dart sac or its homologue in the Helicoidea. Monacha kuznetsovi might therefore be a suitable model organism to study how the interplay between sexual selection and natural selection may affect the evolution of the genital organs.
