D. Andersen. 2018. Aquatic snails of the Snake and Green River Basins of Wyoming. Report prepared by the Wyoming Natural Diversity Database for the Wyoming Fish and Wildlife Department. 1 Abstract Freshwater snails are a diverse group of mollusks that live in a variety of aquatic ecosystems. Many snail species are of conservation concern around the globe. About 37-39 species of aquatic snails likely live in Wyoming. The current study surveyed the Snake and Green River basins in Wyoming and identified 22 species and possibly discovered a new operculate snail. We surveyed streams, wetlands, lakes and springs throughout the basins at randomly selected locations. We measured habitat characteristics and basic water quality at each site. Snails were usually most abundant in ecosystems with higher standing stocks of algae, on solid substrate (e.g., wood or aquatic vegetation) and in habitats with slower water velocity (e.g., backwater and margins of streams). We created an aquatic snail key for identifying species in Wyoming. The key is a work in progress that will be continually updated to reflect changes in taxonomy and new knowledge. We hope the snail key will be used throughout the state to unify snail identification and create better data on Wyoming snails.

Hydrobiidae Descriptions
An Ecological, Morphological and Molecular Investigation of Beddomeia Species (Gastropoda: Hydrobiidae) in Tasmania Karen Richards BScEd, Melbourne College of Advanced Education BAppSc (Hons), Deakin University A thesis submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy University of Tasmania September 2010 ii Declaration This thesis contains no material which has been accepted for the award of any other degree or diploma by the University or any other institution.

Karen Richards Date Statement of Authority of Access This thesis may be made available for loan and limited copying is permitted in accordance with the Copyright Act 1968. Karen Richards Date iii iv Abstract Narrow-range endemic species are thought to have naturally small distributions, limited by size, mobility, dispersal capabilities, specific habitat requirements and biogeographical boundaries. Many narrow range taxa are poorly reserved and most threatened freshwater invertebrate taxa in Tasmania, including the majority of Beddomeia species, fall into this category. Management of such taxa is reliant on informed ecological data which is not currently available for many freshwater invertebrates. To address the need for more detailed information on one such group of aquatic invertebrates, this study obtained spatial and ecological data for a number of Beddomeia species and identified habitat variables that together explained the snail distributions. A combination of geology, catchment size, forest type, flow and disturbance were identified as significant explanatory variables of Beddomeia presence within a river catchment.

Phylogeography and Molecular Species Delimitation Reveal Cryptic Diversity in Potamolithus (Caenogastropoda: Tateidae) of the Southwest Basin of the Andes Gonzalo A
www.nature.com/scientificreports OPEN Phylogeography and molecular species delimitation reveal cryptic diversity in Potamolithus (Caenogastropoda: Tateidae) of the southwest basin of the Andes Gonzalo A. Collado1,2, Cristian Torres‑Díaz1,2 & Moisés A. Valladares1,2* The species of the genus Potamolithus inhabiting the southwestern basin of the Andes are difcult to distinguish due to small size and similar shell morphology. Only Potamolithus australis and Potamolithus santiagensis have been traditionally recognized in this region, but the occurrence of several morphologically similar undescribed populations could increase the regional richness. Here we delimit described and potentially undescribed cryptic species of the genus using partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene. Network analysis and diversity indices inferred six highly diferentiated haplogroups, many of them sympatric and widespread in the study area. Phylogeographic analyses suggest a scenario of recent diversifcation and the occurrence of multiple refuges during the successive Pleistocene glaciations. Phylogenetic analysis also recovered six major clades that showed no relationship with physiography. Species delimitation analyses consistently recognized three or four candidate species apart from P. australis and P. santiagensis. Divergence times indicate that speciation of Chilean Potamolithus began at the end of the Pliocene, probably driven by climatic rather than geographic events. Considering the high inter‑ and intra‑basin genetic

The current classification has relied heavily on features of the shell, which vary within and across drainages, and often intergrade without sharp distinctions between species. The only previous molecular analysis included limited population sampling, which did not allow robust assessment of intra- versus interspecific levels of genetic diversity, and concluded almost every sampled population to be a distinct OTU. We assembled a multilocus mitochondrial (COI, 16S) and nuclear gene (ITS1) dataset for ∼100 populations collected across the range of the genus. We generated primary species hypotheses using ABGD with best-fit model-corrected distances and further explored our data, both individual gene partitions and concatenated datasets, using a diversity of phylogenetic and species delimitation methods (Bayesian inference, maximum likelihood estimation, StarBEAST2, bGMYC, bPTP, BP&P). Our secondary species delimitation hypotheses, based primarily on the criterion of reciprocal monophyly, and informed by a combination of geography and morphology, support the interpretation that Juga comprises a mixture of geographically widespread species and narrow range endemics.

Hydrobiid Snail (Farnhams Creek)
Threatened Species Link www.tas.gov.au SPECIES MANAGEMENT PROFILE Beddomeia fultoni Hydrobiid Snail (Farnhams Creek) Group: Mollusca (shellfish), Gastropoda (snails and slugs), Hypsogastropoda, Tateidae Status: Threatened Species Protection Act 1995: endangered Environment Protection and Biodiversity Conservation Act 1999: Not listed Endemic Endemic in Tasmania and restricted Status: Beddomeia fultoni is a tiny (3-4 mm) freshwater snail occurring in tributaries of Fixters Creek and Farnhams Creek, west of Christmas Hills, north western Tasmania. The species has a relatively narrow range, known only from six streams. The principal threats to B. fultoni are associated with domestic water extraction and refuse dumping, and agricultural and forestry practices, resulting in habitat modification or degradation. B. fultoni may also be vulnerable to competition with the exotic snail Potamopyrgus antipodarum, a New Zealand hydrobiid. The principal management objectives for B. fultoni include preventing the loss or degradation of habitat at known localities, increasing public awareness of the species, and improving its reservation status. Key Points Important: Is this species in your area? Do you need a permit? Ensure you’ve covered all the issues by checking the Planning Ahead page. Important: Different threatened species may have different requirements. For any activity you are considering, read the Activity Advice pages for background information and important advice about managing around the needs of multiple threatened species. Habitat 'Habitat’ refers to both known habitat for the species (i.e. in or near habitat where the species has been recorded) and potential habitat (i.e. areas of habitat with appropriate characteristics for the species and within the species' potential range which have not yet been adequately surveyed).
