The direction that a snail (Mollusca: Gastropoda) coils, whether dextral (right-handed) or
sinistral (left-handed), originates in early development but is most easily observed in the …

Several methods or tests and various software are currently being developed for analyzing
data in population genetics and ecology, which often rely on computer-intensive algorithms …

Restriction site-associated DNA sequencing (RADseq) was used to jointly assess
phylogenetic relationships, interspecific hybridization and species delimitation in the cryptic …

We compared the results of different approaches for delimiting species based on single‐
locus DNA sequences with those of methods using binary multilocus data. As case study, we …

The land snail genus Albinaria exhibits an extreme degree of morphological differentiation
in Greece, especially in the island of Crete. Twenty‐six representatives of 17 nominal …

Distributions of species often exhibit nested structure, such that assemblages at species‐
poor sites are proper subsets of taxa at more species‐rich sites. Traditionally, this has been …

We investigated whether ranges in continental biota are nested. We propose a test for
nested subset structure which can detect nestedness even if there are several sets of nested …

Individual marking has long been used in many fields of biology. However, capture–mark–
recapture (CMR) studies are not evenly distributed among taxonomic groups, with most …

Two groups of subspecies of the door snail Charpentieria itala are distributed in a mosaic
pattern in the Southern Alps. Some subspecies that morphologically resemble Charpentieria …

Aim We investigated the patterns of species richness in land snails and slugs along a
tropical elevational gradient and whether these patterns correlate with area, elevation …
