“…A close phylogenetic relationship between these three genera is consistent with the unique female reproductive groundplan that they share among the North American nymphophilines (Hershler et al, 2003a). Subsequent molecular analyses of Pyrgulopsis were restricted to small groups of species and focused on relationships within single geographic regions (Hershler et al, 2003b;Hershler and Liu, 2004b;Hurt, 2004;Liu et al, 2003). In this paper, we analyze mitochondrial DNA sequences from a much larger set of congeners.…”

“…Since this pattern is replicated in various analyses of three mitochondrial genes, we are confident that our results approximate "biological reality." Fossil evidence suggests that Pyrgulopsis minimally originated during the late Miocene (Hershler and Liu, 2004b), a turbulent period in which the subdued mid-Tertiary western landscape (Gresens, 1978(Gresens, , 1981Potochnik and Damon, 1986) was disrupted by tectonic activity and the complex, mountainous physiography of the present day region began to take shape (Christiansen and Yeats, 1992). This dynamic setting could have provided the stage for rapid radiation of the western nymphophilines into diverse lineages which were jointly splintered by range uplift and other tectonic events, resulting in the phylogenetic mosaic that is now found in individual physiographic regions.…”

“…Therefore, they are suitable for the evaluation of old (pre-Pleistocene) biogeographic relationships. Many of the present-day representatives of the freshwater Rissooidea are considered relicts, the distributions of which trace the Neogene drainage patterns fragmented by subsequent changes in climate and landscape (Hershler and Liu 2004). This hypothesis involves two conditions: (i) the springs inhabited by those obligatorily aquatic animals are stable habitats; and (ii) the gene flow among them, if at all present, is very low.…”

“…In the abundant literature on the phylogeny and population genetic structure and gene flow of spring fauna, gastropods are well represented (e.g. Colgan and Ponder 1994;Ponder et al 1995;Falniowski et al 1998Falniowski et al , 1999Falniowski et al , 2009Bohonak 1999;Hershler and Liu 2004;Brändle et al 2005;Hershler et al 2005;Falniowski and Szarowska 2011). Most studies indicate low levels of gene flow and high levels of endemism in spring snails (e.g.…”

Pseudamnicola Paulucci, 1878 (Caenogastropoda: Truncatelloidea) from the Aegean Islands: a long or short story?

et al. 2015

The aims of the study were (i) to reveal the pattern of phylogeny of Pseudamnicola inhabiting the Aegean Islands, (ii) to describe and analyse the variation of the morphology in 17 populations of Pseudamnicola from the springs on the Aegean Islands not studied so far and considering also another seven populations studied earlier and (iii) to find out which model is more applicable to the island Pseudamnicola populations: either a model in which a relict fauna rich in endemics is differentiated in a way that mainly reflects the geological history of the area or a model in which a relatively young fauna is composed of more or less widely distributed taxa, with relatively high levels of gene flow among the springs they inhabit. To address the above issues, the morphology and the mitochondrial genes-cytochrome oxidase subunit I (COI) and ribosomal 16S-and nuclear genes-ribosomal 18S, 28S and histone 3 (H3)-were analysed. COI and COI+16S rRNA+18S datasets gave trees with identical topology in both ML and Bayesian inference. The 24 studied populations of Pseudamnicola form 16 clades, each of them generally having low levels of intrapopulation genetic differentiation. The generalised mixed Yule coalescent (GMYC) procedure and the Automatic Barcode Gap Discovery (ABGD) analysis for COI identified 16 Pseudamnicola entities coinciding with clades of the ML tree based on 44 haplotypes and 189 sequences. The present pattern of diversity, together with dating of divergence time, reflects a short story of colonisation/recolonisation, supported by the Late Pleistocene land bridges, rather than the consequences of earlier geological events. The principal component analysis (PCA) on the shells of the molecularly distinct clades showed differences, although variability ranges often overlap. Female reproductive organs showed no differences between the clades, and penile characters differed only in some cases.

Assessing the conservation status of the land snail Oreohelix peripherica wasatchensis (Family Oreohelicidae)

Establishing conservation priorities for invertebrate groups has proven difficult as many proposed units of diversity are based on morphological features that do not reflect evolutionary history. This confusion is confounded by poorly defined ranges of proposed endemic and endangered groups, leading to problems formulating adequate conservation management strategies. We examined one such group, Oreohelix peripherica wasatchensis, a landsnail located in the Wasatch Front Range of Utah that is a candidate for protection under the Endangered Species Act. We employed a broad sampling approach to determine the current range of O. p. wasatchensis, including the type locality, several localities in the surrounding Wasatch Mountains, and localities throughout Utah, Nevada, and Colorado. From these samples, we sequenced the mitochondrial DNA loci 12S and Cytochrome Oxidase I (COI) and nuclear loci Internal Transcribed Spacers 1 and 2 (ITS1 and ITS2) and 5.8S. We estimated phylogenetic relationships using maximum likelihood and Bayesian analyses. Molecular data and radula morphology data indicate that the group identified as O. p. wasatchensis falls into two distinct clades. We recommend further ecological and population assessments of these two distinct mitochondrial clades based on the newly defined range to evaluate its endangered status under the IUCN criteria.
