Electrophoretic studies of genetic variation in 14 species of terrestrial slugs of the families Arionidae, Philomycidae, and Limacidae in the eastern United States indicate that self-fertilization, either facultative or obligatory, is the normal breeding system in six of the species. Three of these six species are single monogenic strains; one consists of three monogenic strains; one includes a highly heterozygous form and two monogenic strains; and one has a moderate amount of polymorphism but little heterozygosity and strong linkage disequilibrium. Eight species are outcrossers, being highly polymorphic and panmictic within local populations. Niche breadth, assessed in terms of extent of geographic distribution and variety of habitats occupied and measured on an experimental plot of woodland, is greater in some monogenic strains than in highly heterozygous, outcrossing species. Colonizing success apparently is independent of the amount of genetic variation carried by a species. 5 pp., 4.…

Ten flexible characters for two collections of a pulmonate land slug that differed in their method of preservation (ethanol or freezer/ethanol), were measured four times twice with calipers and twice with a stage micrometer by two different people. Repeated measurements were used to estimate the measurement error (ME) associated with the ten characters. ME ranged from 2% to 90% and differed significantly between the characters. Characters with low mean values and a high flexibility showed the largest ME. With the stage micrometer, one measurer obtained significantly higher ME, but both measurers obtained the same ME with calipers. There was no detectable effect of preservation method on the size and shape of characters, yet, results differed when characters were measured with either calipers or a stage micrometer. One measurer obtained significantly larger mean values for three characters with calipers. Additionally, presumed species differences between three Carinarion species (Arion fasciatus, A. silvaticus and A. circumscriptus; subgenus Carinarion Hesse 1926) were tested using principal component analysis and canonical discriminant analysis. Despite possible measurer biases and high ME, the different datasets yielded highly similar results, indicating that biometrical data of soft, flexible structures may yield valuable and reliable data which can be examined statistically. Our results indicate that A. fasciatus is larger than the other two species, but it is hard to distinguish from both of the other species when size is not considered. Arion silvaticus and A. circumscriptus can be separated only when colour characters are used. 10 pp., 2 figs, 4.…

Surveys in the summers of 1977 (8 locs) and 1978-1979 (111 locs) on 17 islands in the Faroes yielded 20 species (9 slugs and 11 snails) of terrestrial gastropods. Punctum pygmaeum Draparnaud was recorded for the first time and the total number of species known from the Faroes is now 20. All Faroese species also occur in the neighbouring areas (i. e. Scotland, Orkneys, Shetland, Iceland, and Western Norway) with a few minor exceptions. Many of the species (especially the slugs) have wide distributions and are relatively abundant in the Faroes (10 species were found on > 15 islands and 5 species on 8-13 islands). The remaining exhibit relatively broad habitat niches, though many show an association with man-made habitats and may have been introduced by man. Data on numbers, habitat distribution, and distribution maps for the Faroes are given for all species. 14 pp., 20 maps, gr. 8.…

New and little-known terrestrial slugs are dealt with based on extensive collections made in East Africa (Kenya, Tanzania, and Uganda) 19932007. This account deals primarily with larger species from forests in the Eastern Arc Mountains of Tanzania. In Veronicellidae, Pseudoveronicella Germain, 1908 is extended to Tanzania by P. (Hoffmannia) zootoca tanzaniensis subsp. n. in the Udzungwa Mts. In Urocyclidae, Dendrolimax parensis sp. n. is described from the Pare Mts. and Leptichnoides avisexcrementis sp. n. is described from the Uluguru Mts. In Urocyclinae, Tanzalimax tattersfieldi gen. & sp. n. is described from the Usambara Mts., Tanzalimax seddonae gen. & sp. n. from the Uluguru Mts., and Udzungwalimax suminis gen. & sp. n. from the Udzungwa Mts. In addition, the ill-defined genus Atrichotoxon Simroth, 1910 is discussed and the little-known Dendrolimax leprosus Pollonera, 1906 is reported from Uganda. In Agriolimacidae, a species of Deroceras Rafinesque, 1820 is reported for the first time from southern Tanzania. The taxonomic attribution and significance of each discovery is discussed. 32 pp., 75 figs, gr. 8.…

Blanda. Condizione: New. Condizione sovraccoperta: Nuevo. 0. In recent years, slugs have become increasingly important as agricultural and horicultural pests and also as experimental animals, particularly in the field of neurophysiology. This book is a review of the current knowledge of the biology and ecology of slugs, together with their status and control as pests. It is intended particularly to provide a starting point for anyone beginning reseach on a particular aspect of slug biology. It contains an extensive bibliography and is the definitive reference work on these fascinating creatures. Tony South was formerly a Principal Lecturer in the Departament of Biological Sciences, City of London Polytechnic. 640 gr. No Aplica (illustratore). Libro.…
