Dave Clarke, Craig Walker and Paul Atkin Invertebrate Conservation Centre, Zoological Society of London. Regent's Park. London NW1 4RY, UK Abstract Pearce-Kelly, P., Clarke, D., Walker, C. and Atkin, P., 1 997. A conservation programme for - the partulid tree snails of the Pacific region. Memoirs ofthe Museum of Victoria 56(2): 43 1 433. Throughout the Pacific numerous endemic mollusc species have either become extinct in the wild or are currently facing the threat of extinction as a result of introduction of the predatory snail Euglandina rosea and the New Guinea flatworm Platyclemus manokwari. Without determined conservation efforts, including the establishment of ex situ breeding programmes, much of the region's endemic snail fauna will be lost. Since 1986 a collabor- ative international conservation programme has been in place for partulid tree snails. The participating institutions currently maintain a total of 33 taxa in culture (comprising > 12 000 snails). The conservation status of all 1 17 partulid species has been assessed usingthe Conservation Action Management Plan (CAMP) process. Target ex situ population sizes required to maintain 90% of starting heterozygosity over 100 years have been calculated using the analytical model programme CAPACITY (Pearce-Kelly et al., 1994) The genetic management requirements of the breeding programme have necessitated the development of a colony management computer database enabling demographic management and analy- sis of the populations. -

ATKINS Abstracts Soil CaCO. levels were determined for six ecosystems in Washtenaw and Wayne Counties, Michigan and in Linn County, Iowa; and correlation between these results and the shell thickness of certain terrestrial snails was made. Species used were Anguispira alternata ( Say), Triodopsis multilineata (Say), and T. albolabris (Say). Two ecosystems had high caco. levels ( 120-144 ppm), three had intermedi ate levels ( 93-99ppm) and one had a low level ( 40 ppm). 'Width/thickness ratios of live and cast shells showed that those in high calcium ecosystems had thicker shells than those in low calcium ecosystems, though there were large de viations in the thickness values. -

F. Müller) is recorded for the first time in Romania. Other Mediterranean and Balkan species have entered the south of Romania – Dobrogea, or will do so in the near future. We expect the rest of Romania to be invaded, because the Danube is not an insurmountable barrier for some of these species.

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.

86 Animal Miraculum Discovery of Living Anguispira Alternata (Say
Discovery of Living Anguispira alternata (Say, 1816) (Discidae: Gastropoda) in Louisiana, USA Russell L. Minton*, Erin L. Basiger, and Casey B. Nolan Department of Biology, University of Louisiana at Monroe, 700 University Avenue, Monroe, LA 71209-0520, USA (Accepted January 29, 2010) Of the 13 recognized species of Anguispira in the US, 2 are listed as occurring in Louisiana (NatureServe 2009). (A) Anguispira alternata (Say, 1819) is a pulmonate land snail found throughout the eastern US, including states bordering the Mississippi River to the west (Hubricht 1985). The other species, A. strongylodes (Pfeiffer, 1854), is found across the southern US, with a range that narrowly overlaps A. alternata at its northern boundary. The shell of A. strongylodes differs from that of A. alternata by lacking streaks along the base and the umbilicus and by having smaller spots along the shell periphery (Pilsbry 1948). Hubricht (1985) listed only fossil A. alternata as occurring in Louisiana and Mississippi, while NatureServe (2009) lists it as extirpated in both states. Pilsbry viewed strongylodes as a weakly differentiated subspecies of A. alternata endemic to east-central Texas, although Hubricht (1960) later elevated strongylodes to species status and established its currently recognized range (Hubricht 1985). During a recent survey of Black Bayou Lake National Wildlife Refuge (32.6°N, 92.04°W) in Monroe, LA, we collected (B) a number of living and dead specimens that matched the original description and other published images of A. alternata and not A. strongylodes. These specimens possessed the color patterns described by Pilsbry (1948), most notably prominent spots on the periphery and streaks on the underside that separate A. -

Bibliography of RNDr. Vojen Ložek, DrSc., is compiled on the occasion of his ninetieth birthday. The present list includes 1338 items. ▒ Key words: molluscs, Holocene, Pleistocene, malacofauna, Quaternary, karst, landscape, malacology, malacostratigraphy, biostratigraphy, zoostratigraphy, chronostratigraphy, caves, loess, limestone, Central Europe, palaeoecology, Bohemia, Moravia, Slovakia, Carpathians, calcareous tufa, climatic changes, nature conservation Úvod Dr. Vojen Ložek, DrSc., se narodil 26. července 1925. Jeho celoevropský význam zhodnotila řada autorů (viz dále). K jeho devadesátinám předávám do tisku jeho úplnou bibliografii, která aktuálně čítá 1338 publikací, za jeden rok tedy vydal průměrně 17 prací! Jsou to jak práce, které napsal sám, tak se spoluautory, články i větší studie a velké monografie. To samo již vypovídá o jeho nezměrné píli a vědeckém zaměření v nejrůznějších oborech. Kromě publikovaných prací sepsal desítky odborných posudků a zpráv o průbězích svých výzkumů. Vedle toho všeho také sestavil mapy přirozených 421 BOHEMIA CENTRALIS 33 hnojiv a minerální síly půd v měřítku 1 : 200 000 s obsáhlými texty k nim, které slouží zvláště zemědělcům. Jde o soubor map pokrývající prakticky celou plochu tehdejšího Československa, celkem 31 listů! Na Ložkově bibliografii jsem pracoval průběžně po celou řadu let. Vedle separátů a knih, které mi jubilant postupně věnoval, získával jsem od něj také seznamy jeho publikací, které jsem doplňoval o jeho další, při mých studiích zjištěné práce, které mu nedopatřením ušly, neboť redakce některých periodik mu třeba zapomněly poslat autorské výtisky, takže se nedostaly do jeho seznamu. -

Armed Snaggletooth Gastrocopta Armifera ILLINOIS RANGE
armed snaggletooth Gastrocopta armifera Kingdom: Animalia FEATURES Phylum: Mollusca One-eighth inch is the largest shell dimension of this species. Class: Gastropoda Snails have a complex system of organs. The mouth contains Order: a radula, a flexible, ribbonlike structure lined with rows of teeth, used to scrape food. On the head are tentacles. Most Family: Vertiginidae snails in Illinois have an eye at the tip of each upper tentacle. ILLINOIS STATUS A snail’s shell develops in the egg along with the rest of its body and continues to grow until the snail reaches sexual common, native maturity. The shell is formed by deposits of calcium laid down by the mantle. As the shell grows in its coiled shape, whorls are added. A snail cannot leave its shell. It has a strong muscle inside that is firmly attached to the shell. Snail shells grow in a variety of shapes. Shell shape, number and type of whorls and shell ornamentation, such as ribs or hairs, aid in identification of species. Snail shells may persist long after the snail has died and often can be used to identify species. The shell of this snail has projections, called teeth or denticles, in its aperture that help protect its soft body from being eaten by insect predators. BEHAVIORS Snails need to seek sheltered places to live, eat and rest. They prefer to live in moist areas and are commonly found under logs, loose bark or coarse woody debris, and in leaf litter on the forest floor. In general, snail populations are greatest in areas that have high soil calcium levels.
