Paraphyly and budding speciation in the hairy snail (Pulmonata, Hygromiidae)
The phylogenetic analyses based on 12S, 16S and COI sequences show that the T. hispidus complex is paraphyletic with respect to several other morphologically well‐defined Trochulus species, but the results of a parallel morphometric investigation did not reveal any differentiation between these clades, although the overall variability is quite high.

The morphology and ecology of representatives of the taxonomically ambiguous genus Trochulus, which comprises several genetically highly divergent mitochondrial clades, is investigated and it is suggested that its subspecies spent at least the last glaciation in or close to the presently inhabited areas.
GENETIC DIFFERENTIATION AND SHELL MORPHOLOGY OF TROCHULUS OREINOS (WAGNER, 1915) AND T. HISPIDUS (LINNAEUS, 1758) (PULMONATA: HYGROMIIDAE) IN THE NORTHEASTERN ALPS

Trochulus oreinos oreinos and T. oreinos scheerpeltzi are two land snail taxa endemic to the Northeastern Austrian Alps, which have been regarded as subspecies of the highly variable, widespread land…
New data on the phylogeny of Ariantinae (Pulmonata, Helicidae) and the systematic position of Cylindrus obtusus based on nuclear and mitochondrial DNA marker sequences
The results provide strong support for the sister-group relationship between Cylindrus and Arianta confirming previous studies and imply that the split between the two genera is quite old, as well as revealing a phylogeographical pattern of Ariantinae with a well-supported clade comprising the Balkan taxa.
Phylogeography and systematics of Pyramidula (Pulmonata: Pyramidulidae) in the eastern Alps: still a taxonomic challenge
The results provide insights on Pyramidula within the eastern Alpine region, suggesting that it survived the Pleistocene oscillations without dramatic bottlenecks and is capable of fast expansion to (re)populate formerly glaciated areas.

The north-west alpine distributed hairy snail Trochulus clandestinus (Hartmann, 1821) was recorded for the first time from Austria and it cannot be clearly stated whether the species settled in Vorarlberg directly after the end of the last glaciation or whether the current finding is a result of recent anthropogenic introduction.
Chromosome numbers of terrestrial mollusks (Mollusca: Gastropoda) of Georgia
In the present study chromosome numbers in terrestrial mollusks of Georgia (Caucasus region) were investigated. Chromosome plates (with both haploid as well as diploid chromosome set) were obtained…
In Search of Glacial Refuges of the Land Snail Orcula dolium (Pulmonata, Orculidae) - An Integrative Approach Using DNA Sequence and Fossil Data

The reconstruction of geographic range history suggests that O. dolium is of Western Carpathian origin and diversified already around the Miocene-Pliocene boundary, and the fossil record supports the species’ presence at more than 40 sites during the last glacial and earlier cold periods.
Detection of Crenosoma spp., Angiostrongylus vasorum and Aelurostrongylus abstrusus in Gastropods in Eastern Austria
The present study confirms the enzooticity of major cardiorespiratory nematodes in Austria and that canine and feline populations are at risk of infection.
