“…It may be that populations of Helix are generally more geographically structured, as geographic population structure is considered one of the factors responsible for preservation of deep intraspecific mitochondrial lineages in land snails (Thomaz, Guiller, & Clarke, 1996;Sauer & Hausdorf, 2012; see also Slatkin, 1991). The pattern observed in H. thessalica (spatially restricted divergent lineages with shallow internal diversity; Figures 1 and 2) is the one expected when the species' sub-populations are isolated (Criscione & Köhler, 2016;Papadopoulou et al, 2008). Caucasotachea vindobonensis is smaller and thus supposedly better suited for passive dispersal (Cameron, Pokryszko, & Horsák, 2010;Hausdorf & Hennig, 2003;Nekola, 2014) than the Helix species, so there may be more gene flow across its range.…”

Exact locations of glacial refugia are relevant for the study of contemporary biodiversity, not only as places less disturbed during the climatic changes but also as sources of rapid expansion of the biota after the Last Glacial cycle. If continuously inhabited over several of the Quaternary glacial cycles, the refugia are readily identifiable by the accumulated genetic diversity. However, the sources of the Holocene range expansion, particularly important for the emergence of present‐day bio‐ and phylogeographic patterns and for realistic estimation of species’ expansion rates, might have been located at the fringes of the glacial species ranges and lack unique lineages. This problem is pertinent when the variation is explored at slowly evolving genetic markers. We suggest that the location of such source refugia may be approximated by reconstructing the geographic location as a continuous trait evolving along the branches of a phylogenetic tree. We applied this approach, using the BEAST software, on two large southeast European land snail species: Caucasotachea vindobonensis and Helix thessalica. We found evidence for C. vindobonensis refugia in the western Balkans; notable is an apparently old refugium in Bosnia and Herzegovina. The plausible sources of the species’ Holocene range expansion, however, were located around the south‐western end of the Carpathians. Although the source areas were likely similar in H. thessalica, some expansion sources suggested by the analyses (e.g., Podolia, Ukraine) appeared implausible and driven by sampling clustered in that area. The applied approach allows for additional exploitation of the mitochondrial data gathered during the past two decades of animal phylogeography studies.

“…Nevertheless, we consider the available mitochondrial evidence as an overall reliable indicator for the systematic relationships within this group and for the need to critically revisit the current species‐level taxonomy. This conclusion is based on an extensive body of literature that underpins the systematic utility and reliability of mtDNA markers in Australian camaenids (e.g., Burghardt & Köhler, 2014; Criscione & Köhler, 2014a, 2014b, 2016a, 2016b; Köhler & Burghardt, 2015; O'Neill, Johnson, Hamilton, & Teale, 2014) as well as the observation of a marked phylogeographic structure in the phylogenetic tree (Figure 3). However, the discrepancy between BI and ML topologies and relatively low basal branch support values for many nodes indicate difficulties in reliably resolving more ancient splits among Austrochloritis species.…”

We analyzed the mitochondrial differentiation of the southeast Australian land snail genus Austrochloritis Pilsbry, 1890, family Camaenidae, which encompasses 34 currently accepted species. These species were exclusively described and delimited based on comparative shell morphology, while their reproductive anatomy has remained undocumented. Phylogenetic analyses of partial fragments of the cytochrome c oxidase subunit 1 gene (COI) and 16S rRNA (16S) genes revealed widespread incongruence between the shell‐based species taxonomy and the branching patterns of phylogenetic trees indicating the urgent need of more comprehensive systematic review. The phylogeographic patterns in Austrochloritis are consistent with well‐documented biogeographic barriers in southeastern Australia, namely the Hunter River Valley and the McPherson Range, which demarcate concomitant biogeographic breaks in the biota of the region. These breaks are thought to result from past expansions and contractions of mesic forests caused by the climatic oscillations during the mid to late Neogene. Our study also provides evidence for potentially widespread sympatry of Austrochloritis species in the northern part of their distribution, which is in conflict with contemporary paradigms that presume predominantly allopatric distributions in congeneric land snails in eastern Australia.

“…Organisms having higher fecundity and abundance tend to be more competitive 49 . The complex topography and geomorphology, varied physical conditions and a wide diversity of ecosystems in mountainous areas may result in allopatric and sympatric speciation 50 , 51 . Based on the dominance of C. cicatricosa in these areas, we must analyze physiological and ecological sections of this species in future research.…”

The phylogeographic structure of the land snail Camaena cicatricosa was analyzed in this study based on mitochondrial gene (COI and 16srRNA, mt DNA) and internal transcribed spacer (ITS2) sequences in 347 individuals. This snail is the vector of the zoonotic food-borne parasite Angiostrongylus cantonensis and one of the main harmful snails distributed exclusively in China. The results revealed significant fixation indices of genetic differentiation and high gene flow between most populations except several populations. An isolation-by-distance test showed no significant correlation between genetic distance and geographical distance among C. cicatricosa populations, which suggested that gene flow was not restricted by distance. The levels of haplotype and nucleotide diversity of C. cicatricosa were generally high, except those in some special populations, according to the mt DNA and ITS2 data. Furthermore, the phylogenetic trees and asteroid networks of haplotypes indicated nonobvious genetic structure, the same as results got based on the synonymous and non synonymous sites of 347 sequences of the COI gene. All lines of evidence indicated that climatic changes and geographical and human barriers do not substantially affect the current population structure and distribution of the investigated snails.
