Aim To investigate latitudinal and altitudinal patterns in body size variation among north-west European land snail species, as well as factors influencing such patterns. Location Latitudinal patterns were investigated in north-west Europe from the British Isles and France in the west to Finland, Poland, Slovakia and Hungary in the east and from Norway in the north to France (with the exception of the Mediterranean part of the country), Switzerland, Austria and Hungary in the south. Altitudinal patterns were examined in the Alps in Austria and Switzerland. Methods Data on latitudinal ranges of 366 north-west European land snail species, on altitudinal ranges of 175 species from Austria and 150 species from Switzerland, and on their body sizes were used to test for the presence of interspecific latitudinal or altitudinal body size patterns. Four methods, Stevens method, the midpoint method, the across-species method, and a phylogenetically controlled analysis (CAIC) were applied. Results As a result of the predominance of some small bodied clades at higher latitudes and some large bodied clades at lower latitudes, body size of north-west European land snails decreases significantly with increasing latitude. However, little of the body size variation across species is explained by latitude and the phylogenetically controlled analysis showed that the decrease of body size with increasing latitude is not a result of repeated and independent evolution of an association between body size and latitude in many clades. There is no significant correlation between body size of land snail species and altitude in the Alps although a negative correlation of body size and altitude is frequent within species. Main conclusion If phylogenetic effects are controlled for, neither latitudinal nor altitudinal patterns in body size could be found. Bergmann's rule, which predicts a positive correlation between body size of species and latitude, could not be confirmed for north-west European land snails. 6 pp., 7 figs, 4.

The vitrinids, which represent a probably competitively inferior transitional stage between shelled snails and slugs, and their sister group, the limacoid slugs, are used to investigate a macroevolutionary effect of a microevolutionary process, competition between individuals resulting in ecological displacement of one clade by another, based on patterns in the present-day world. The activity period and the altitudinal distribution of the vitrinids has shifted to the cold season or to higher altitudes, respectively in those regions where their range overlaps with that of the limacoid slugs. The diversity of the vitrinids is lower in regions with limacoid slugs. These patterns can be ascribed to the ecological displacement or the exclusion of the vitrinids from some habitats by limacoid slugs. Two vitrinid clades which independently colonized regions without limacoid slugs show patterns attributable to ecological release. The ecological displacement or exclusion of the vitrinids by the slugs is probably due to competition for shelter. 9 pp., 2 figs, 1 tab, 4.

Megalena, gen. nov. is described as a new genus of Buliminidae, Eninae. It is characterized by the large shell without apertural teeth or with only a weak angular tooth, the lack of a diverticulum to the bursa copulatrix, and by the inner structures of the penis, namely two strong longitudinal rolls which delimit a groove in the proximal section of the penis and the lack of a penial papilla. The only species included in Megalena gen. nov. is Megalena crassa (Retowski) which is known from Northwestern Anatolia. Paramastus goettingi Forcart is a synonym. 6 pp., 4 figs, gr. 8.

A new cladistic method for the estimation of ancestral areas is based on reversible parsimony in combination with a weighting scheme that weights steps in positionally plesiomorphic branches more highly than steps in positionally apomorphic branches. By applying this method to cladograms of human mitochondrial DNA, the method is superior to previously proposed algorithms. The method is also an appropriate tool for the solution of the redundant distribution problem in area cladograms. Under the assumption of allopatric speciation, redundant distributions, i.e., sympatry of sister groups, show that dispersal has occurred; thus, the ancestral area of at least one sister group was smaller than the combined distribution of its descendants. With the weighted ancestral area analysis, the ancestral areas can be confined and at least some dispersal events can be distinguished from possible vicariance events. As applied to a cladogram of the Polypteridae, weighted ancestral area analysis is superior to Brooks parsimony analysis (assumption 0) and component analysis under assumptions 1 and 2 (Nelson and Platnick, 1981, Systematics and biogeography: Cladistics and vicariance. Columbia Univ. Press, New York.) in resolving redundancies. The results of the weighted ancestral area analysis may differ from the results of dispersal-vicariance analysis, because the rules of dispersal-vicariance analysis indirectly favor the questionable assumption that the ancestral species occupied only one unit area. 12 pp., 5 figs, gr. 8.

Partial Mantel tests and structural equation models were used to investigate the influence of recent geography, palaeogeography and climate on the composition of the fauna of the central Aegean Islands. The composition of land snail and isopod island faunas was significantly influenced by recent and by Pliocene geography. Only Pleistocene palaeogeography had a significant influence on the composition of tenebrionid beetle island faunas. The composition of butterfly island faunas was influenced by recent and by Miocene geographical distances. The composition of reptile island faunas was correlated with recent and Pliocene geography as well as with Pleistocene and/or Miocene geographical distances. Island area influenced only the composition of the island faunas of the volant butterflies, and not that of the less mobile land snails, land isopods, tenebrionid beetles and reptiles. This might indicate that butterflies are able to colonize large islands with suitable habitats even if such islands are comparatively far from source areas more frequently than can the nonvolant groups. Influence of a climatic parameter, namely annual precipitation, on faunal composition was found only for reptiles. 11 pp., 3 figs, 4.

The latitudinal and altitudinal range sizes of north-west European land-snail species increase with increasing latitude/altitude. These Rapoport effects are not caused by northern/high-altitude species with wider latitudinal/altitudinal ranges and southern/low-altitude species with narrower latitudinal/altitudinal ranges, as predicted by the climatic variability hypothesis. They are instead caused mainly by different northern/upper borders of species occurring in the south part of the study area or at low and intermediate altitudes, respectively. This pattern indicates that the observed Rapoport effects are the result mainly of differential northward/upward expansion of species that were restricted to southern/low or intermediate altitude refugia during the glacials. Although all species occurring in a refugium experienced the same climatic conditions, there is stochastic variation in their climatic tolerance. Species with broader climatic tolerance were able to expand farer northwards/upwards postglacial. The altitudinal distribution of species richness in the analysed alpine faunas cannot be explained by the Rapoport-rescue hypothesis, because species richness peaks at intermediate altitudes and because there is no negative correlation between the number of range borders and altitude. The Rapoport-rescue hypothesis alone is probably also insufficient to explain the decrease in species richness with increasing latitude. 15 pp., 14 figs, 4.

Aim: Reconstruction of the historical biogeography of the Limacoidea sensu lato (including the Staffordiidae, Dyakiidae, Gastrodontoidea, Parmacelloidea, Zonitidae, Helicarionoidea and Limacoidea). Evaluation of the relative importance of dispersal and its consequences. Location: World-wide. Methods: Weighted ancestral area analysis. Results: The ancestral areas of the individual clades have been delimited using weighted ancestral area analysis and a sequence of possible vicariance and dispersal events has been suggested. The results of the ancestral area analysis have tentatively been correlated with Cretaceous and Tertiary palaeogeography. The widely overlapping distribution patterns of several families of the Limacoidea testify to extensive dispersal events. Dispersal capacity of land snails is correlated with body size. The significant negative correlation between body size and distribution area size corroborates the importance of passive dispersal for the evolution of the distribution patterns. Main conclusions: The existence of extensive dispersal events of poor active dispersers like land snails diminishes the importance of recent distribution patterns for the reconstruction of palaeogeography. On the other hand, dispersal ensures that biogeographical data reflect the geographical configurations at a given time and renders the use of palaeobiogeographic data for the reconstruction of palaeogeographic configurations of the respective age possible. 12 pp., 6 figs, tabs, 4.

Seven Monacha species have been found in the Western Caucasus region. Six of these species are endemic there. They all belong to the subgenera Paratheba and Metatheba. Three species are new to science. Monacha (Paratheba) claussi, sp. n. and Monacha (Metatheba) subcarthusiana (Lindholm) are the only Monacha species, in which the right ommatophoral retractor sometimes crosses with the penis. This might be due to an ancestral polymorphism, atavism or a basal position of the two species within Monacha, which would mean that Paratheba is paraphyletic and Metatheba is polyphyletic. Monacha (Monacha) cartusiana (O. F. Müller), the only Monacha sensu stricto species in the Caucasus region, has probably been introduced by man. The shell and the genitalia of every species are described and illustrated. The synonyms and all Caucasian locality records are listed. The distributions of the species are illustrated on UTM-grid maps. New taxa: Monacha (Paratheba) claussi n. sp., Monacha (Paratheba) kuznetsovi n. sp., Monacha (Metatheba) ciscaucasica n. sp., 20 pp., 19 figs, gr. 8.

This paper presents a comprehensive revision of Circassina (Gastropoda: Hygromiidae). Circassina is divided into two subgenera. The nominotypical subgenus is characterized by an inflation forming a brim at the base of the dart apparatus, whereas Circassina (Abchasohela) is characterized by a granular shell sculpture. Circassina (Circassina) includes C. frutis (with the subspecies C. f. frutis, C. frutis circassica and C. frutis veselyi), which ranges from the northwestern slope of the Caucasus Mountains throughout most of Georgia to northernmost Armenia and the Eastern Pontic Mountains in Turkey, and C. lasistana new species, which is only known from the Vileyet Artvin in Turkey. Circassina (Abchasohela) includes C. christophori, C. pachnodes, C. pergranulata new species, C. septentrionalis new species and C. stephaniae. All species of Circassina (Abchasohela) are restricted to Abkhasia and the adjacent Russian regions in westernmost Caucasia. The shell and the genitalia of each taxon are described and illustrated. All synonyms and all locality records are listed. The distribution of the species is illustrated on a UTM-grid map. New taxa: Circassina lasistana n. sp., Circassina pergranulata n. sp., Circassina septentrionalis n. sp. 22 pp., 30 figs, 4.
