Bosworth III1 ABSTRACT.—Oreohelix eurekensis uinta had not been found since its original discovery and had never been reported as a living taxon, and this had led to speculation that it is extinct. However, searches for O. e. uinta had been confounded by multiple errors in the original definition of the type locality. The type locality has now been relocated and is here redefined, and O. -

For instance, the common redstart is a bird species breeding in the lowlands, whereas the black redstart is native to higher altitudes. Some species such as common swift and kestrel, which are originally adapted to enduring in rocky areas, even found a secondary habitat in the house facades and street canyons of towns and big cities. Classic rock dwellers include peregrine, eagle owl, rockthrush, snowfinch and alpine swift. The presentation focuses on the biology, causes of threat as well as conservation measures taken by the national park concerning the species golden eagle, wallcreeper, crag martin and ptarmigan. Birds breeding in the rocks might not be that high in number, but their survival is all the more fascinating and worth protecting as such!

A New Approach to an Old Conundrumdna Barcoding Sheds
Molecular Ecology Resources (2010) doi: 10.1111/j.1755-0998.2010.02937.x DNA BARCODING A new approach to an old conundrum—DNA barcoding sheds new light on phenotypic plasticity and morphological stasis in microsnails (Gastropoda, Pulmonata, Carychiidae) ALEXANDER M. WEIGAND,* ADRIENNE JOCHUM,* MARKUS PFENNINGER,† DIRK STEINKE‡ and ANNETTE KLUSSMANN-KOLB*,† *Institute for Ecology, Evolution and Diversity, Siesmayerstrasse 70, Goethe-University, 60323 Frankfurt am Main, Germany, †Research Centre Biodiversity and Climate, Siesmayerstrasse 70, 60323 Frankfurt am Main, Germany, ‡Biodiversity Institute of Ontario, University of Guelph, 50 Stone Road West, Guelph, ON N1G 2V7, Canada Abstract The identification of microsnail taxa based on morphological characters is often a time-consuming and inconclusive process. Aspects such as morphological stasis and phenotypic plasticity further complicate their taxonomic designation. In this study, we demonstrate that the application of DNA barcoding can alleviate these problems within the Carychiidae (Gastro- poda, Pulmonata). These microsnails are a taxon of the pulmonate lineage and most likely migrated onto land indepen- dently of the Stylommatophora clade. Their taxonomical classification is currently based on conchological and anatomical characters only. Despite much confusion about historic species assignments, the Carychiidae can be unambiguously subdi- vided into two taxa: (i) Zospeum species, which are restricted to karst caves, and (ii) Carychium species, which occur in a broad range of environmental conditions. The implementation of discrete molecular data (COI marker) enabled us to cor- rectly designate 90% of the carychiid microsnails. The remaining cases were probably cryptic Zospeum and Carychium taxa and incipient species, which require further investigation into their species status. Because conventional reliance upon mostly continuous (i.e. -
Pupillid Land Snails of Eastern North America*
Amer. Malac. Bull. 28: 1-29 (2010) Pupillid land snails of eastern North America* Jeffrey C. Nekola1 and Brian F. Coles2 1 Department of Biology, University of New Mexico, Albuquerque, New Mexico 87131, U.S.A. 2 Mollusca Section, Department of Biodiversity, National Museum of Wales, Cathays Park, Cardiff CF10 3NP, U.K. Corresponding author: [email protected] Abstract: The Pupillidae form an important component of eastern North American land snail biodiversity, representing approx. 12% of the entire fauna, 25-75% of all species and individuals at regional scales, at least 30% of the species diversity, and 33% of individuals within any given site. In some regions pupillids represent 80-100% of total molluscan diversity within sites, notably in taiga, tundra, and the base-poor pine savannas and pocosins of the southeastern coastal plain. Adequate documentation of North American land snail biodiversity thus requires investigators to effi ciently collect and accurately identify individuals of this group. This paper presents a set of annotated keys to the 65 species in this family known to occur in North America east of the Rocky Mountains. The distinguishing taxonomic features, updated county-scale range maps, and ecological conditions favored by each are presented in hopes of stimulating future research in this important group. Key words: microsnail, biodiversity, ecology, biogeography, taxonomy For the last dozen years, our interests in terrestrial Adequate documentation of this diversity thus requires gastropod biodiversity have lead us individually and investigators to effi ciently collect and accurately identify collectively to observe molluscan communities over most of individuals from this family. Unfortunately, neither has been North America, ranging from central Quebec, Hudson’s Bay common. -

The species has previously been known only as a Pliocene fossil, but now is recognized in the Quaternary of the southwest United States, and living in the Pecos Valley of New Mexico. Pecosorbis is unusual because of its restricted distribution and habitat in seasonal rock pools. Most similar to Menetus, it differs in having a preputial organ with an external duct, no spermatheca, and a penial sac that is mostly eversible. -

Fum.oNG With two text-figures 49 CAPROMERYX MINOR TAYLOR FROM THE McKITTRICK PLEISTOCENE, CALIFORNIA INTRODUCTION The occurrence of a Pleistocene vertebrate fauna in an e.sphalt deposit near McKittrick, California, has been reported by J. C. Merriam and C. Stock. Since the publication of the provisional list of mammals from this locality, several types new to the assemb lage have been discovered in the deposit. Among these should be recorded the small antilocaprid, Capromeryx minor. This species occurs here in association with the prong-horn antelope Antilocapra. Three species of the genus Capromeryx are now known from the Pleistocene of North America. The type, C. furcifer, was described by Matthew 1 from Hay Springs, Nebraska. C. minor Taylor 2 occurs at Rancho La Brea, and C. mexicana Furlong 8 is recorded from Tequixquiac, Mexico. The occurrence of C. minor at McKittrick extends the range of this species during the Pleistocene from the Los Angeles basin to the Great Valley of California. Members of the family Antilocapridre are apparently sparsely represented in the McKittrick fauna, as only one individual of Capromeryx has been found, while several individuals of Antilocapra are known to occur. -

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. -

Kanab Ambersnail (Oxyloma Kanabense)
TOC Page | 88 KANAB AMBERSNAIL (OXYLOMA KANABENSE) Navajo/Federal Statuses: NESL G4 / listed endangered 17 APR 1992 (57FR:13657). Distribution: Only two populations known: 1) near Kanab in Kane County, UT; 2) at Vasey's Paradise in Grand Canyon National Park (75.3 km downstream of Glen Canyon Dam). Potential is likely restricted to western Navajo Nation; including tributaries of Colorado and Little Colorado Rivers, springs on Echo Cliffs, and creeks north and west of Navajo Mountain. Habitat: Restricted to perennially wet soil surfaces or shallow standing water and decaying plant matter associated with springs and seep-fed marshes near sandstone or limestone cliffs. Vegetative cover is necessary; cattails, monkeyflower, or watercress are present at the two known locations, but wetland grasses and sedges may suffice. Similar Species: other Succineid snails; see Pilsbry, 1948. Phenology: m.MAR-l.MAR: emergence from winter dormancy by previous year’s young e.APR-e.JUL: maturation e.JUL-l.AUG: peak reproduction l.AUG-l.SEP: growth of young, die-off of adults >l.SEP: growth of young, winter dormancy Survey Method: Pedestrian surveys within suitable habitat examining on and under wetland vegetation for live or dead snails. Federal permit required for collection. Suggested reference: Spamer and Bogan, in press. Avoidance: No surface disturbance year-round within 60 m of occupied habitat; no alteration of water quantity and chemistry. References: Pilsbry, H.A. 1948.
