AnotationThe project will deal mainly with systematic and phylogenetic studies of two selected groups of Atlantic and Indo-Pacific crustaceans (Decapoda) - shrimps (Caridea) and crabs (Brachyura). These will be performed on marine shrimps of the families Alpheidae and Palaemonidae, as well as on swimming crabs Portunidae. The analysed shrimps were symbiotic with worms or burrowing crustaceans, or associated with corals, echinoderms and marine sponges. The studies will thematically follow the projects of the proponent and coproponents carried out in previous years, and, among others, they will newly devote attention to the phylogeny and taxonomic revision of the polyphyletic shrimp genus Periclimenes. A collection of shrimps and crabs available at the Department of Biology and Ecology of the Faculty of Science at the University of Ostrava, as well as rich material already loaned from cooperating experts from international museums in Paris, Leiden, and Taiwan, will be used for taxonomic revisions. To test the genetic identity of selected taxa, partial mitochodrial gene sequences will be compared; multigene analyses will be applied to verify wider phylogenetic hypotheses. The outputs of this project will be mainly the finalization of the results of the taxonomic revision of the basal complex of Pontoniinae. Works will also continue on revisions of the crab genera Cycloachelous and Lupocyclus, as well as on the shrimp genus Salmoneus and related genera. Initial draft molecular phylogenies and desriptions of new taxa within the current genus Periclimenes and spongobiotic palaemonid shrimps will be performed. Selected outputs will be submitted to international impact-factor journals, partial results might be presented at national and international scientific conferences.
