Identifying species of Bythinella (Caenogastropoda: Rissooidea): A plea for an integrative approach
TLDR
The phylogenetic analyses suggest that B. opaca has colonized Carinthia, which has largely been covered by glaciers during the last ice age, along two routes, one from the south and a secondOne from the southeast.

The spermathecal epithelium, sperm and their interactions in the hermaphroditic land snail Arianta arbustorum (Pulmonata, Stylommatophora)
TLDR
The ultrastructure of the spermathecal epithelium is analysed, a brief description of the sperm morphology and the sperm–epithelium interactions are described and it is assumed that the epithelia provides the environment for sperm quiescence rather than nutritives.

Mitochondrial differentiation in a polymorphic land snail: evidence for Pleistocene survival within the boundaries of permafrost
TLDR
The clear genetic differentiation and the patchy pattern of haplotype distribution suggest that colonization of formerly unsuitable habitats was mainly achieved from multiple populations from within the permafrost area.

Variation in spermathecal morphology and storage of spermatozoa in the simultaneously hermaphroditic land snail Arianta arbustorum (Gastropoda: Pulmonata: Stylommatophora)
TLDR
Morphological investigations showed that the sperm storage organ (spermatheca) of the simultaneously hermaphroditic land snail Arianta arbustorum consists of 2–8 tubules with a common entrance, which suggests that the female reproductive system of A. arb Bustorum may possibly be able to control fertilization by a selective storage of spermatozoa from different mating partners.

Radiation of crenobiontic gastropods on an ancient continental island: the Hemistomia-clade in New Caledonia (Gastropoda: Hydrobiidae)
TLDR
A vast radiation of hydrobiid spring snails endemic to New Caledonia, a continental island in the Southwest Pacific known for its unique flora and fauna, is described and many of the taxa are highly threatened to become extinct in the closer future as a consequence of human activities.

Rapid and convergent evolution of parental care in hydrobiid gastropods from New Zealand

  • 1 July 2005
TLDR
The syntopy of two congeneric species, one oviparous and the other one brooding, indicated that the transition between reproductive modes must have occurred rapidly, and maximum parsimony and Markov chain models of character state transformations in a maximum likelihood framework suggested that hydrobiids have invaded freshwater three times independently.

Variation in spermathecal morphology and amount of sperm stored in populations of the simultaneously hermaphroditic land snail Arianta arbustorum
TLDR
Results indicate that the risk of sperm competition does not affect the complexity of the spermatheca (number of sperMathecal tubules) in this snail, however, the possibility that individuals in high-density populations store sperm from more different mating partners than those in low- density populations remains to be examined.
