The Light–Dark Cycle of Desmoulin's Whorl Snail Vertigo Moulinsiana Dupuy, 1849

Książkiewicz–Parulska Książkiewicz–Parulska, Z., 2018. The light–dark cycle of Desmoulin’s whorl snail Vertigo moulinsiana Dupuy, 1849 (Gastropoda, Pulmonata, Vertiginidae) and its activity patterns at different temperatures. Animal Biodiversity and Conservation, 41.1: 109–115, Doi: https://doi.org/10.32800/abc.2018.41.0109 Abstract The light–dark cycle of Desmoulin’s whorl snail Vertigo moulinsiana Dupuy, 1849 (Gastropoda, Pulmonata, Vertiginidae) and its activity patterns at different temperatures. Vertigo moulinsiana is a minute land snail spe- cies which requires high humidity conditions and is found in wet, temporarily inundated habitats. The species is listed in the IUCN Red List of Threatened Species under the VU (vulnerable) category and is considered a high conservation priority. It is also mentioned in Annex II of the EU Habitat Directive, which imposes the obligation to monitor the species in member countries. The monitoring of V. moulinsiana is based on counting individuals attached to plants in the field, and thus any results may only be properly evaluated when the behavior of the species is understood. Therefore, the aim of this study was to investigate the light–dark cycle of both adults and juveniles within the species as well as to compare activity patterns of both age groups in dark conditions in tem- peratures of 6 ºC and 21 ºC. Observations were carried out under laboratory conditions, at a high and constant humidity (humidity was at or nearly 100 %). -
An Annotated List of the Non-Marine Mollusca of Britain and Ireland
JOURNAL OF CONCHOLOGY (2005), VOL.38, NO .6 607 AN ANNOTATED LIST OF THE NON-MARINE MOLLUSCA OF BRITAIN AND IRELAND ROY ANDERSON1 Abstract An updated nomenclatural list of the non-marine Mollusca of the Britain and Ireland is provided. This updates all previous lists and revises nomenclature and classification in the context of recent changes and of new European lists, including the Clecom List. Cases are made for the usage of names in the List by means of annotations. The List will provide a basis for the future census and cataloguing of the fauna of Britain and Ireland. Key words Taxonomic, list, nomenclature, non-marine, Mollusca, Britain, Ireland, annotated. INTRODUCTION There has been a need for some time to modernise the list of non-marine Mollusca for Britain and Ireland, a subject last visited in this journal in 1976 (Waldén 1976; Kerney 1976). Many of the changes that have appeared in the literature since then are contentious and Kerney (1999) chose not to incorporate many of these into the latest atlas of non-marine Mollusca of Britain and Ireland. A new European List, the Clecom List (Falkner et al. 2001) has now appeared and it seems appropriate to examine in more detail constituent changes which might affect the British and Irish faunas. This is given additional urgency by the inception of a new census of the molluscs of Britain and Ireland by the Conchological Society. Recorders in the Society are aware of many of the proposed changes but unable to implement them without general agreement. In addition, many field malacologists make use of the recording package RECORDER, a recent form of which has been developed jointly by JNCC and the National Biodiversity Network in the United Kingdom. -

Vol. 10(1): 1–7 AN OVERVIEW OF THE DATA ON THE TERRESTRIAL MOLLUSCS IN LITHUANIA . GRITA SKUJIENE Department of Zoology, Vilnius University, Èiurlionio 21/27, Vilnius LT-2009, Lithuania (e-mail: [email protected]) ABSTRACT: Data on species of land snails and slugs of Lithuania published during the last 160 years are sum- marized and compared with the most recent information from Poland and Latvia. A total of 83 species of 18 families of terrestrial molluscs have been recorded from Lithuania: 68 snail and 15 slug species. The occur- rence of two of them: Vertigo genesii (Gredler) and Aegopinella nitens (Michaud) is doubtful. Data on terrestrial molluscs of adjacent countries indicate that 20 more species can be expected to be found in Lithuania. Two of them would be new also to Poland or Latvia: Vertigo lilljeborgi (Westerlund, 1871) and Zoogenetes harpa (Say, 1824).

Vertigo Geyeri
Report under the Article 17 of the Habitats Directive European Environment Period 2007-2012 Agency European Topic Centre on Biological Diversity Vertigo geyeri Annex II Priority No Species group Molluscs Regions Alpine, Atlantic, Boreal, Continental Geyer’s Whorl Snail Vertigo geyeri is a boreo-alpine species, probably endemic to Europe. It is present in the Boreal, Alpine, Continental and Atlantic zones. Vertigo geyeri is stringent in its requirement of saturated water conditions in calcareous, ground water fed flushes that are often limited in size to a few metres square. Their habitats often occur in mosaics of suitable patches within wider fen macrohabitats. It is a groundwater-dependant species. The conservation status in the Alpine region is “unfavourable–inadequate “. Five Member States report the main pressures and threats as grassland removal for arable land, abandonment / lack of mowing, landfill, land reclamation and drying out, general, water abstractions from groundwater, species composition change (succession), droughts and less precipitations, habitat shifting and alteration. The conservation status in the Atlantic region is “unfavourable–inadequate “. United Kingdom and Ireland report grazing and abandonment of pastoral systems, lack of grazing as pressures and threats of high importance in the region. The conservation status in the Boreal region is “unfavourable–bad “. Sweden reports the abandonment of pastoral systems, lack of grazing, forestry activities not referred to above, nitrogen-input, canalisation & water deviation, water abstractions from groundwater as a main pressures and threats in the country. The human induced changes in hydraulic conditions and biocenotic evolution, succession as pressures or threats were reported Lithuania. Estonia reports the modification of hydrographic functioning, general as pressure of high importance. -

108 Kalkman (ed) 2008 MOLLUSKEN (LANDSLAKKEN - EN ZOETWATER WEEKDIEREN ) INLEIDING In Nederland leven behalve in zee en brakwater, ook landslakken en aquatische molluskensoorten in zoet water. Zoals iedere tuinliefhebber weet, kunnen sommige landslakken algemeen en (te) opvallend aanwezig zijn. Voorbeelden zijn de grote segrijnslak Helix aspersa, de gewone tuinslak Cepaea nemoralis en de grote wegslak Arion rufus. Diverse andere soorten, tref je echter alleen in meer specifieke biotopen aan. In het algemeen gaat het niet goed met de Nederlandse mollusken. Meerdere soorten zijn al geheel of vrijwel geheel uit ons land verdwenen. Toen dit besef eenmaal doordrong binnen het natuurbeleid en -beheer, kwam er meer onderzoek naar deze lang vergeten, vooral verborgen levende diergroep. Daarbij bleek al snel dat diverse ook buiten ons land zeldzame en bedreigde soorten alleen nog in natuurgebied en vaak in fragmentjes van hun vroegere biotopen voorkomen. Daarbuiten leiden ze een marginaal bestaan in overhoekjes als spoor- en wegbermen en -dijken en geïsoleerde wateren in gebieden die genomineerd zijn anders ingericht te worden of geheel te verdwijnen. Levenswijze Op het land leven alleen huisjesslakken en naaktslakken, in het water daarnaast ook tweekleppigen. Van de landslakken hebben veel soorten een zekere kalkbehoefte; sommigen meer dan anderen. De laatste tref je dan ook vooral aan op plaatsen met kalk, zoals Zuid-Limburg en in de duinen. Er zijn echter ook soorten van zuurdere biotopen, alsmede van zeer natte, moerasachtige omstandigheden, deels uitdrogende greppels of drogere plaatsen. Landslakken zie je vooral 's nachts en onder vochtige omstandigheden tijdens mist en regen. Fel licht en droogte worden gemeden. De dieren kruipen dan diep weg op schaduwrijke plaatsen die nog een beetje vochtig blijven.
