“…1), are generally secure, but reported to be declining. O. strigosa is distributed from Southern Montana to Northern Arizona, and from Eastern Washington to Eastern Colorado [38]. This species was once common and widespread across the Colorado Front Range in the early 1900s, since then, observers have found that fewer populations remain ( [32,39], personal observation).…”

Background The Rocky Mountainsnail (Oreohelix strigosa) is a terrestrial gastropod of ecological importance in the Rocky Mountains of western United States and Canada. Across the animal kingdom, including in gastropods, gut microbiomes have profound effects on the health of the host. Current knowledge regarding snail gut microbiomes, particularly throughout various life history stages, is limited. Understanding snail gut microbiome composition and dynamics can provide an initial step toward better conservation and management of this species. Results In this study, we employed 16S rRNA gene amplicon sequencing to examine gut bacteria communities in wild-caught O. strigosa populations from the Front Range of Colorado. These included three treatment groups: (1) adult and (2) fetal snails, as well as (3) sub-populations of adult snails that were starved prior to ethanol fixation. Overall, O. strigosa harbors a high diversity of bacteria. We sequenced the V4 region of the 16S rRNA gene on an Illumina MiSeq and obtained 2,714,330 total reads. We identified a total of 7056 unique operational taxonomic units (OTUs) belonging to 36 phyla. The core gut microbiome of four unique OTUs accounts for roughly half of all sequencing reads returned and may aid the snails’ digestive processes. Significant differences in microbial composition, as well as richness, evenness, and Shannon Indices were found across the three treatment groups. Conclusions Comparisons of gut microbiomes in O. strigosa adult, fetal, and starved samples provide evidence that the host internal environments influence bacterial community compositions, and that bacteria may be transmitted vertically from parent to offspring. This work provides the first comprehensive report on the structure and membership of bacterial populations in the gastropod family Oreohelicidae and reveals similarities and differences across varying life history metrics. Strong differentiation between these life history metrics demonstrates the need for wider sampling for studies of dynamics of the snail gut microbiome.

“…The Phantom Cave snail was not treated in a subsequent review of the cochliopid genera (Hershler & Thompson, 1992) and in recent works is either tentatively retained in Cochliopa (e.g. Turgeon et al, 1998) or listed as genus incertae sedis (e.g. Burch, 1989).…”

The Phantom Cave snail (Cochliopa texana), a little-studied rissooidean gastropod that is locally endemic within the lower Pecos River basin (Texas) and currently a candidate for addition to the Federal list of threatened and endangered species, is redescribed and transferred to the hydrobiid genus Pyrgulopsis, based on shell and anatomical characters. Specimens from the type locality (Phantom Lake Spring) and San Solomon Spring are larger than those from East Sandia Spring and also differ somewhat in shell shape and shape of the central cusps of the lateral radular teeth. However genetic (mtCOI, NDI) variation within and among these geographically proximal (6-13 km) populations was slight, providing no basis for the recognition of distinct conservation units of this imperiled species. We also describe Pyrgulopsis ignota n. sp., which was recently discovered in a different part of the lower Pecos River basin and initially confused with the Phantom Cave snail. These two species differ in shell shape, operculum morphology, and form and glandular ornament of the penis. They are also strongly differentiated genetically from each other and from (13) other regional congeners ( pairwise sequence divergence .6.3% for both genes). A Bayesian phylogenetic analysis of the COI and NDI dataset indicated that these two snails are not closely related and that P. ignota occupies a basal position relative to other regional congeners.

“…These recommendations are generally appropriate for freshwater invertebrates, but we further encourage researchers and agencies to explore the systematics and taxonomy of those gastropod groups that have not been treated in the modern literature. Hydrobiidae (e.g., Hershler 1994, Hershler andPonder 1998) and Pleuroceridae (e.g., Tryon 1873, Holznagel and Lydeard 2000, Graf 2001) are the 2 largest freshwater gastropod families in North America (Turgeon et al 1998). Systematic and taxonomic reassessments of these families and smaller families, such as Physidae (Wethington and Lydeard 2007), have been initiated recently.…”

“…Burch (2001) identified this issue in a critical review of Dillon (2000). Turgeon et al (1998) provided a list of names that are accepted generally in the field, and we recommend using it as the single starting point for modern nomenclature, while acknowledging that future work probably will change it. Inconsistent use of names also fails to present the most current understanding of a species.…”

The roles of systematics in the field of conservation biology are well understood and accepted for many organisms. However, the role of systematics and taxonomy has not been reviewed in the context of species protection and management of freshwater gastropods. We provide a thorough review of the relevant theoretical literature in systematics and taxonomy and illustrate with recent examples of species delineation and taxonomy in North American freshwater gastropods that these fields play key roles in the practical designation of conservation management units. We summarize some aspects of the biology of freshwater gastropods that can confound taxonomic and management efforts. Based on our review, we recommend that effective conservation plans include the systematic research necessary to recognize unique organismal lineages as primary conservation management units. This strategy must be combined with consistent and rigorous nomenclature, taxonomy, and dissemination of research findings so that all parties have access to the highest quality information.
