Many aquatic organisms rely on passive transport of resting stages for their dispersal. In this
review, we provide evidence pointing to the high dispersal capacity of both animals …

Although hybridization and introgression have been considered important in generation of
plant diversity, their role in evolutionary diversification of animals remains unclear. In this …

Cladocera is a primarily-freshwater monophyletic group, an important component of the
microcrustacean zooplankton. They inhabit most types of continental fresh and saline water …

Three species of Darwin's finches (Geospiza fortis, G. scandens, and G. fuliginosa) hybridize
rarely on the small Galapagos island of Daphne Major. Following the exceptionally severe …

Literature on local genetic differentiation in freshwater zooplankton populations is reviewed.
The island-like nature of limnetic habitats creates opportunities for local genetic …

The cosmopolitanism paradigm in the biogeography of freshwater invertebrates is currently
being replaced by non-cosmopolitanism or continental endemism. Benthic water fleas …

The Daphnia longispina complex contains some of the most common water flea species in
the northern hemisphere, and has been a model organism for many ecological and …

Background Genetically divergent cryptic species are frequently detected by molecular
methods. These discoveries are often a byproduct of molecular barcoding studies in which …

Cladoceran crustaceans are an important component of zooplankton in a wide range of
freshwater habitats. Although the ecological characteristics of several cladoceran species …

Dormancy is a suspension of the vital functions in an organism for a certain, sometimes very
long, time period to overcome harsh environmental conditions. It is a widespread adaptation …
