TERRESTRIAL GASTROPODS OF THE UPPER FRASER BASIN | 5 The majority of British Columbia’s terrestrial molluscs are tiny and usually overlooked in general natural his- tory surveys. Prior to the Royal BC Museum handbook, Land Snails of British Columbia (Forsyth 2004) only 100 km two publications (Stanwell-Fletcher & Stanwell-Fletcher 55 1943; Harris & Hubricht 1982) report any species from the upper Fraser Basin. Even the landmark monograph of Pilsbry (1939–1948) does not list locality records from this large area of British Columbia. This report documents the species of terrestrial mol- luscs known from the upper Fraser Basin, and gives the results of recent fieldwork. For further information on the species documented here, see Land Snails of British Columbia (Forsyth 2004), which includes full descrip- tions, figures and keys. – 1 MATERIALS AND METHODS 2 0 Most of the records documented here are the result of a reconnaissance survey of the upper Fraser Basin in July Figure 2 Collection localities (from all sources) in the upper Fraser Basin (see Appendix for data). 2001.

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).

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.

  • Lincoln National Forest
    Chapter 1: Introduction In Ecological and Biological Diversity of National Forests in Region 3 Bruce Vander Lee, Ruth Smith, and Joanna Bate The Nature Conservancy EXECUTIVE SUMMARY We summarized existing regional-scale biological and ecological assessment information from Arizona and New Mexico for use in the development of Forest Plans for the eleven National Forests in USDA Forest Service Region 3 (Region 3). Under the current Planning Rule, Forest Plans are to be strategic documents focusing on ecological, economic, and social sustainability. In addition, Region 3 has identified restoration of the functionality of fire-adapted systems as a central priority to address forest health issues. Assessments were selected for inclusion in this report based on (1) relevance to Forest Planning needs with emphasis on the need to address ecosystem diversity and ecological sustainability, (2) suitability to address restoration of Region 3’s major vegetation systems, and (3) suitability to address ecological conditions at regional scales. We identified five assessments that addressed the distribution and current condition of ecological and biological diversity within Region 3. We summarized each of these assessments to highlight important ecological resources that exist on National Forests in Arizona and New Mexico: • Extent and distribution of potential natural vegetation types in Arizona and New Mexico • Distribution and condition of low-elevation grasslands in Arizona • Distribution of stream reaches with native fish occurrences in Arizona • Species richness and conservation status attributes for all species on National Forests in Arizona and New Mexico • Identification of priority areas for biodiversity conservation from Ecoregional Assessments from Arizona and New Mexico Analyses of available assessments were completed across all management jurisdictions for Arizona and New Mexico, providing a regional context to illustrate the biological and ecological importance of National Forests in Region 3.

In Latvia, this species was first recorded in 1989 in Liepāja. Observations in recent years in Liepāja have shown that snails from their initial introduction sites on the railway have also spread to the sand dune habitats within the city limits. Given that there are no snails in dune habitats that are biologically equivalent to X. obvia, this species is considered to be potentially invasive. As the distribution trends of this species in Liepāja indicate a possible threat to dry habitats in natural areas, detailed study of the species was conducted for the population of this species located in Dobele. Monitoring was performed from May 26 to August 5, 2019, carrying out 11 surveys with one week interval using the capture and re-capture method. The maximum recorded distance travelled by of one snail was 29.7 m; the calculated minimum estimated population density was 170 individuals and the maximum was 2004 individuals. Key words: alien species, Dobele population, eastern heath snail, Helicella candicans, Helicella obvia, potentially invasive species.

VINARSKI Saint-Petersburg State University, Universitetskaya Naberezhnaya, 7/9, 199034 Saint-Petersburg/Omsk State Pedagogical University, 14 Tukhachevskogo Emb., 644099 Omsk, Russian Federation (e-mail: [email protected]) ABSTRACT: The history of the species problem as applied to freshwater molluscs, from the beginning of scientific taxonomy to the present day, is outlined. Three main approaches to delineation of species boundaries (intuitive, conceptual, and operational) are discussed, with remarks on their practical usage in freshwater malacology. The central topic of the article is how malacologists changed their views on the essence of species category and the impact of these changes on the taxonomic practice. The opinions of some prominent and prolific workers in the field (Bourguignat, Kobelt, Hubendick, Starobogatov) are analysed as well as the debates around the theoretical foundations and practical results of the ‘Nouvelle École’ of the 19th century and the ‘comparatory’ systematics of the 20th century.

Abstract: Terrestrial mollusks (land snails and slugs) are an important component of the terrestrial ecosystem, yet for most species their distribution is not well known.
