Gene flow between populations that are adapting to distinct environments may be restricted
if hybrids inherit maladaptive, intermediate phenotypes. This phenomenon, called extrinsic …

We examined the seasonal patterns of physiology and biochemical composition in the rock-
dwelling clausiliid land snail Albinaria caerulea in relation to its ecology, morphology and …

Background Mitochondrial DNA sequencing increasingly results in the recognition of
genetically divergent, but morphologically cryptic lineages. Species delimitation approaches …

Consider a group of species that is evenly divided by an easily identifiable complex
morphological character. Most biologists would assume that this character should provide …

The high level of biodiversity and endemism of Greece are noticeable and Greece is the
most diverse, in proportion to its area, Mediterranean country in all levels of biodiversity. The …

We studied dispersal patterns in a representative population of the rock-dwelling land snail
Albinaria coerulea (Clausiliidae), to obtain direct estimates of gene flow and to predict the …

Studies on the diversity of land molluscs raise a number of crucial questions that remain
unanswered, or in some cases have not been asked. At the most fundamental level, we …

In land snails, a change in the direction of coiling, being associated with a shift in the
position of the genital apparatus, may act as a barrier against hybridization between …

Mitochondrial DNA sequences from 16S rRNA and ATPase8 genes were used to investigate
phylogeographic patterns of the land snail Albinaria (Gastropoda: Clausiliidae) in the …

Morphological variation of snails from the genus Trochulus is so huge that their taxonomy is
unclear. The greatest variability concerns forms hispidus and sericeus/plebeius, which are …
