The species concept is the cornerstone of biodiversity science, and any paradigm shift in the
delimitation of species affects many research fields. Many biologists now are embracing a …

Freshwater amphipods G ammarus fossarum and G ammarus pulex are widespread in
Europe, with some evidence of cryptic diversity in the former. We used DNA barcoding to …

Competition theory states that multiple species should not be able to occupy the same niche
indefinitely. Morphologically, similar species are expected to be ecologically alike and …

Molecular genetic methods continuously uncover cryptic lineages harboured by various
species. However, from an applied perspective, it remains unclear whether and to which …

Recent studies indicate that morphologically cryptic species may be ecologically more
different than would be predicted from their morphological similarity and phylogenetic …

Many amphipod species occur in dense aggregations, cohabit with mating partners for long
time periods, or live in family groups. Although this confers ample opportunities for social …

Predators exert a strong selective force on the ecosystems in which they exist, thereby
altering the structure of ecological communities and leading to the evolution of prey …

As a result of the poor genome sequence coverage of crustacean amphipods,
characterization of their evolutionary biology relies mostly on phenotypic traits. Here, we …

The narrow-headed vole species complex is represented by Lasiopodomys gregalis and L.
raddei, which probably diverged at the beginning of the Middle Pleistocene and came into …

Amphipods are among the most abundant macroinvertebrates in freshwater ecosystems of
the Palaearctic and crucial for ecosystem functioning. Furthermore, their high sensitivity to …
