Snails were collected monthly during the study period and sampled using a combination of indirect litter sample methods and timed direct search. Snails collected were kept in labeled specimen vials and transported to the National Museums of Kenya for identification using keys and reference collection. In order to understand environmental variables that affect soil snail abundance; canopy, soil pH and temperature was measured per plot while humidity and rainfall data was obtained from the nearest weather stations to the study sites. A total of 2881 snail specimens (29 species from 10 families) were recorded. The families Subulinidae, Charopidae and Urocyclidae were found to be dorminant. The most abundant species was Opeas lamoense (12% of the sample). -
The Slugs of Bulgaria (Arionidae, Milacidae, Agriolimacidae
POLSKA AKADEMIA NAUK INSTYTUT ZOOLOGII ANNALES ZOOLOGICI Tom 37 Warszawa, 20 X 1983 Nr 3 A n d rzej W ik t o r The slugs of Bulgaria (A rionidae , M ilacidae, Limacidae, Agriolimacidae — G astropoda , Stylommatophora) [With 118 text-figures and 31 maps] Abstract. All previously known Bulgarian slugs from the Arionidae, Milacidae, Limacidae and Agriolimacidae families have been discussed in this paper. It is based on many years of individual field research, examination of all accessible private and museum collections as well as on critical analysis of the published data. The taxa from families to species are sup plied with synonymy, descriptions of external morphology, anatomy, bionomics, distribution and all records from Bulgaria. It also includes the original key to all species. The illustrative material comprises 118 drawings, including 116 made by the author, and maps of localities on UTM grid. The occurrence of 37 slug species was ascertained, including 1 species (Tandonia pirinia- na) which is quite new for scientists. The occurrence of other 4 species known from publications could not bo established. Basing on the variety of slug fauna two zoogeographical limits were indicated. One separating the Stara Pianina Mountains from south-western massifs (Pirin, Rila, Rodopi, Vitosha. Mountains), the other running across the range of Stara Pianina in the^area of Shipka pass. INTRODUCTION Like other Balkan countries, Bulgaria is an area of Palearctic especially interesting in respect to malacofauna. So far little investigation has been carried out on molluscs of that country and very few papers on slugs (mostly contributions) were published. The papers by B a b o r (1898) and J u r in ić (1906) are the oldest ones. -

It included 47 locali- ties throughout the country. The surveyed invertebrate groups included slugs and snails (Gastropoda), dragonflies (Odonata), grasshoppers (Orthoptera), true bugs (Heteroptera), ants (Formicidae), butterflies (Lepidoptera) and some coleopterans (Staphylinidae: Pselaphinae). Data on the visited localities, identi- fied species and their conservation status are presented. In total, 316 species of 209 genera and 68 families were recorded. Fifty species were identified as potential indicator species for this wetland habitat type. The highest species richness (with more than 50 species) was observed in wetlands near Marino pole (Plovdiv District) and Karaisen (Veliko Tarnovo District). Key words: Gastropoda, Odonata, Orthoptera, Heteroptera, Formicidae, Lepidoptera, Pselaphinae, wetland. Introduction According to the EUNIS Biodiversity Database, all known mire and spring complex according to the wetlands (mires, bogs and fens) are territories with occurrence of rare and threaten plant and mollusc water table at or above ground level for at least half species. -

Pulmonata: Zonitidae) from Sa0 Miguel Island, Azores
Proc. Tenth Intern. Malacol. Congr. mbingen 1989) 1991 COMPARATIVE ANATOMY OF POPULATIONS OF QXYCHZLUS (DRQUEUA) AlL4Nl7CUS (MORELET ET DROUET, 1857) (PULMONATA: ZONITIDAE) FROM SA0 MIGUEL ISLAND, AZORES Ant6nio M. de Frias Martins ABSTRACT The morphology of the reproductive system of Oxychilus fDmuen'a) arlanticus (Morelet & DrouBt, 1857) representing of eight populations from the type locality, SoMiguel Island, Azores was compared. Variation in the relative proportion of the various organs was observed intrapopulationally, either natural or as an artifact due to differential contraction of the animal when preserved. Interpopulational variability was observed, marked in one case, but additional information is needed to justify a taxonomic separation. Shell morphology was observed to vary, some eastern populations showing a more depressed spire. INTRODUCTION Since the work of Morelet & Drouet (1857), the Zonitidae of the Azores remained untouched until Riedel (1964), based on anatomical features, recognized a series of new taxa of the genus Oxychilus Fitzinger, 1833. Riedel called attention to the endemic subgenus Drouetia Gude, 1911, which, pending availability of suitable material, he felt should yield several new species. Indeed four new species have been added since then (Martins, 1981, 1989; de Winter, 1989), and material from several islands is being worked upon, suggesting the addition of more new species (Martins, in preparation). Although in certain cases shell characters are diagnostic (Martins, 1981), the new taxa are based mostly on the anatomy of the reproductive system. However, the variability observed among the populations from Terceira Island (Martins, 1989) prompted this study on material from Sao Miguel Island in order to assess: (1) the variability of the type species, Oxychilus (Drouetia) atlanticus (Morelet et DrouEt, 1857), previously known to exhibit two "forms" (Riedel, 1964); (2) the reliability of using proportional dimensions of the various organs of the reproductive system as the main character for taxonomic decisions. -
Terrestrial Mollusks of Attu, Aleutian Islands, Alaska BARRY ROTH’ and DAVID R
ARCTK: VOL. 34, NO. 1 (MARCH 1981), P. 43-47 Terrestrial Mollusks of Attu, Aleutian Islands, Alaska BARRY ROTH’ and DAVID R. LINDBERG’ ABSTRACT. Seven species of land mollusk (2 slugs, 5 snails) were collected on Attu in July 1979. Three are circumboreal species, two are amphi-arctic (Palearctic and Nearctic but not circumboreal), and two are Nearctic. Barring chance survival of mollusks in local refugia, the fauna was assembled overwater since deglaciation, perhaps within the last 10 OOO years. Mollusk faunas from Kamchatka to southeastern Alaska all have a Holarctic component. A Palearctic component present on Kamchatka and the Commander Islands is absent from the Aleutians, which have a Nearctic component that diminishes westward. This pattern is similar to that of other soil-dwelling invertebrate groups. RESUM& Sept espbces de mollusques terrestres (2 limaces et 5 escargots) furent prklevkes sur I’ile d’Attu en juillet 1979. Trois sont des espbces circomborkales, deux amphi-arctiques (Palkarctiques et Nkarctiques mais non circomborkales), et deux Nkarctiques. Si I’on excepte la survivance de mollusques due auhasard dans des refuges locaux, cette faune s’est retrouvke de part et d’autre des eauxdepuis la dkglaciation, peut-&re depuis les derniers 10 OOO ans. Les faunes de mollusques de la pkninsule de Kamchatkajusqu’au sud-est de 1’Alaska on toutes une composante Holarctique. Une composante Palkarctique prksente sur leKamchatka et les iles Commandeur ne se retrouve pas aux Alkoutiennes, oil la composante Nkarctique diminue vers I’ouest.

Two problematic, troglophilous gastropods from the Peloponnese, Greece (Gastropoda, Pulmonata, Zonitidae). Zool. Med. Leiden 82 (28), 20.vi.2008: 275-280, fi gs 1-4.— ISSN 0024-0672. E. Gitt enberger, National Museum of Natural History 'Naturalis', P.O. Box 9517, NL 2300 RA Leiden, The Netherlands (gitt [email protected]). Key words: Gastropoda; Pulmonata; Oxychilidae; Pristilomatidae; new species; troglodytes; Greece. Two species of pulmonate gastropods are described as new to science although their generic classifi ca- tion remains uncertain since only shells are available for study. The species might be troglodytes. Their shells indicate the presence of subterraneous material. Introduction In 1985 and following years, during several excursions in the eastern part of the Peloponnese, Greece, empty shells of two unknown pulmonate species were found. Their subgeneric or even generic classifi cation is doubtful because of the absence of anatomical data. Probably these species occur in a for humans nearly inaccessible habitat. The snails are most probably troglophilous, if not troglodytic. Their shells may serve as indicators of deposits of subterranean material, which is an argument in favour of naming these species despite the fact that their systematic position remains unclear. Waiting for more data might become a too long wait. Both species were also found in a deposit together with shells of Tsoukatosia liae Gitt enberger, 2000 (Clausili- idae, Serrulininae), a clausiliid species with a glassy transparent shell, also indicative of a subterranean habitat and hitherto known from its type locality only. -
Appendix ES-11 Alien Snail Control in Nurseries
Appendix ES-11 Alien Snail Control in Nurseries Alien snail control in nurseries Report to the Oahu Army Natural Resources Program (OANRP) Prepared by Norine W. Yeung and Robert H. Cowie 30 November 2012 Pacific Biosciences Research Center University of Hawaii 3050 Maile Way, Gilmore 408 Honolulu, Hawaii 96822 Phone: (808) 956 4909/0956 E-mail: [email protected] [email protected] 1 Appendix ES-11 Alien Snail Control in Nurseries BACKGROUND AND PURPOSE From the basic perspective of habitat restoration, non-native species should not be introduced to areas where they are not present. Specifically, non-native snails and slugs (hereafter ‘snails’) may impact both native vegetation (Joe & Daehler 2008) and native snails (Meyer & Cowie 2010a, b, Sugiura et al. 2011) in areas to which they are introduced. Therefore, it is important that plants to be outplanted, as well as equipment and vehicles used to transport plants, are free of non-native snails. This requires appropriate management practices and control measures to be adopted in the nurseries. For some time the OANRP has been planning to outplant native Hawaiian plants on military land on Oahu as part of its ecological restoration efforts. A major problem associated with this effort is that the plants grown in the nurseries for outplanting can become infested with non- native snails (Cowie et al. 2008), some of which, especially as juveniles, are very small (on the order of 1-2 mm). Preliminary discussions and visits to the Schofield baseyard and the nursery at the Nike site took place prior to the implementation of this agreement and the start of the project. -

Canadian Field-Naturalist 133(4): 313–324. https://doi.org/10.22621/cfn.v133i4.2217 Abstract Less than 5% of the original tall grass prairie in North America remains. A portion of this remnant, composed of wetland, grassland and forest, is protected by the Nature Conservancy of Canada (NCC) in southern Manitoba. This heterogene- ous ecosystem has rich biodiversity; however, gastropods have not been surveyed in Canada’s tall grass prairie. We studied gastropods in Prairie, Wet Meadow, Forest, and Wet Forest habitats of the Manitoba Tall Grass Prairie Preserve that vary with respect to land management practices (prescribed burning, grazing by cattle). Gastropod community composition was unique in the Prairie where mounds of grass litter form permanently moist cavities harbouring aquatic species, while dry-habitat species colonized the upper parts of these mounds. Gastropod communities in Prairie habitats were negatively affected by grazing and burning that occurred in the five years prior to our survey.
