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.

Lea, 1834) Family: Succineidae Common name: Blunt Ambersnail Identification Length: 6-14 mm Whorls: 3 This ambersnail is intermediate in size. It has shallower sutures and flatter whorls, giving it a more streamlined look than Catinella vermeta. It also has a taller aperture, about 2/3 the total shell length. The basal margin of its aperture may appear nearly flat, although this may vary to more rounded. The animal is stippled with small black spots, which form bands on top of the head, including a stripe to each antennae. Ecology Oxyloma retusum is often found in damp fields or shoreline habitats, sometimes at high densities in the warmer months. It may be seen crawling in muddy areas or on wetland plants (Hubricht 1985). Along a small lake in Maryland, this species was eating mostly dead plants in the spring, but both live and dead plants in summer and fall (Örstan, 2006). In Maryland a few individuals of this species survive the winter, then grow until the end of June when the larger animals die off following an initial mating period (Örstan, 2006). Offspring from the first mating period Photo(s): Live Oxyloma retusum by Bill engage in their own mating in late summer. Survivors of the spring and late summer generations enter winter Frank ©.

Land Gastropods (Snail & Slugs) of Los Angeles
Land gastropods (snails & slugs) of Los Angeles County Why snails? • Many local species are endemic to Southern California • In fact, land snails are highly endemic around the world. • They evolve adaptations to relatively small locations. • Habitat destruction has put many land snails at high risk of extinction, including almost all of the endemic species in Southern California. Papustyla pulcherrima Manus Green Tree Snail Found: Manus Island, Papua New Guinea Facts: green color is natural but is only in outer protein layer of shell Lifestyle: tree snail, lives in island rainforests Conservation status: Endangered due to over-collection by humans and habitat (native tree) loss from logging Achatinella fulgens O`ahu tree snail Found: O`ahu, Hawaii Facts: sinestral (left-coiling), 41 species, 30 species extinct Lifestyle: tree snail, eats fungus off tree leaves Conservation status: Critically endangered due to predation by rats, introduced snails, and habitat (native tree) loss Zonitoides arboreus S.L.I.M.E Snails & slugs Living Oxychilus sp. In Metropolitan Environments Goals of SLIME • Inventory of living snail species in Los Angeles County • Compare with Museum historical records • Note introductions and extinctions • Ask where and why do populations live where they do What role do snails play in the environment? Many snails are decomposers. Decomposers consume dead or dying leaves, wood, and fungus. Without snails and other decomposers it would take much longer for nutrients to cycle through the environment: that is, move from living things to the soil, then back into living things again. Which snails and slugs are considered pests? Why? Pest snails are those that cause damage to human-grown plants and/or are so abundant that they cause damage to human-created landscapes.

Land Snails and Slugs (Gastropoda: Caenogastropoda and Pulmonata) of Two National Parks Along the Potomac River Near Washington, District of Columbia
Banisteria, Number 43, pages 3-20 © 2014 Virginia Natural History Society Land Snails and Slugs (Gastropoda: Caenogastropoda and Pulmonata) of Two National Parks along the Potomac River near Washington, District of Columbia Brent W. Steury U.S. National Park Service 700 George Washington Memorial Parkway Turkey Run Park Headquarters McLean, Virginia 22101 Timothy A. Pearce Carnegie Museum of Natural History 4400 Forbes Avenue Pittsburgh, Pennsylvania 15213-4080 ABSTRACT The land snails and slugs (Gastropoda: Caenogastropoda and Pulmonata) of two national parks along the Potomac River in Washington DC, Maryland, and Virginia were surveyed in 2010 and 2011. A total of 64 species was documented accounting for 60 new county or District records. Paralaoma servilis (Shuttleworth) and Zonitoides nitidus (Müller) are recorded for the first time from Virginia and Euconulus polygyratus (Pilsbry) is confirmed from the state. Previously unreported growth forms of Punctum smithi Morrison and Stenotrema barbatum (Clapp) are described. Key words: District of Columbia, Euconulus polygyratus, Gastropoda, land snails, Maryland, national park, Paralaoma servilis, Punctum smithi, Stenotrema barbatum, Virginia, Zonitoides nitidus. INTRODUCTION Although county-level distributions of native land gastropods have been published for the eastern United Land snails and slugs (Gastropoda: Caeno- States (Hubricht, 1985), and for the District of gastropoda and Pulmonata) represent a large portion of Columbia and Maryland (Grimm, 1971a), and Virginia the terrestrial invertebrate fauna with estimates ranging (Beetle, 1973), no published records exist specific to between 30,000 and 35,000 species worldwide (Solem, the areas inventoried during this study, which covered 1984), including at least 523 native taxa in the eastern select national park sites along the Potomac River in United States (Hubricht, 1985).

Using data sampled on a nationwide scale from streams in South Korea, we identified the crucial environmental factors influencing the distribution and abundance of freshwater gastropods. We used nonmetric multidimensional scaling and the random forest model to evaluate the relationships between environmental factors and gastropod assemblages. Among the 30 recorded species, two invasive gastropod species (Pomacea canaliculata and Physa acuta) have enlarged their distribution (10.4% and 57.3% frequency of occurrence, respectively), and were found to be widespread in streams and rivers. Our results revealed that the most influential factor in the distribution of gastropod assemblages was the ratio of cobble (%) in the substrate composition, although meteorological and physiographical factors were also important. However, the main environmental factors influencing species distribution varied among species according to habitat preference and environmental tolerance. Additionally, anthropogenic disturbance caused a decrease in the distribution of endemic species and an increase in the spatial distribution of invasive species. Finally, the results of the present study provide baseline information for planning successful strategies to maintain and conserve gastropod diversity when facing anthropogenic disturbance, as well as understanding the factors associated with the establishment of invasive species.

Grand Canyon National Park United States of America
GRAND CANYON NATIONAL PARK UNITED STATES OF AMERICA This is the most spectacular gorge in the world, carved by the Colorado river 1,600m into the plateau that has risen around it. It bisects half the Grand Canyon National Park, and its strata record the geological history of the past 2 billion years. There are also traces of prehistoric human adaptation to this harsh environment. COUNTRY United States of America NAME Grand Canyon National Park NATURAL WORLD HERITAGE SITE 1979: Inscribed on the List of World Heritage sites under criteria vii, viii, ix and x. One of the first four natural World Heritage sites to be established. STATEMENT OF OUTSTANDING UNIVERSAL VALUE [pending] The UNESCO World Heritage Committee issued the following statement at the time of inscription: Statement of Significance The Grand Canyon is among the earth’s greatest on-going geological spectacles. Its vastness is stunning, and the evidence it reveals about the earth’s history is invaluable. The 1.5-kilometer (0.9 mile) deep gorge ranges in width from 500 m to 30 km (0.3 mile to 18.6 miles). It twists and turns 445 km (276.5 miles) and was formed during 6 million years of geologic activity and erosion by the Colorado River on the upraised earth’s crust. The buttes, spires, mesas and temples in the canyon are in fact mountains looked down upon from the rims. Horizontal strata exposed in the canyon retrace geological history over 2 billion years and represent the four major geologic eras. Criterion (vii): Widely known for its exceptional natural beauty and considered one of the world's most visually powerful landscapes, the Grand Canyon is celebrated for its plunging depths; temple-like buttes; and vast, multihued, labyrinthine topography.
