AnotationThe project will deal with phylogenetic, systematic and ecological studies of selected taxa of Arthropods, i.e. shrimps of the families Palaemonidae and Alpheidae and dipterous insects. The link between these studies are, apart from the same methodology (combination of morphological and molecular methods), the symbiotic relationships of these arthropods with other organisms - in case of shrimps it means sponges, corals or echinoderms, and in Diptera it means the association of certain families with their host fungi and plants. In the case of the study of shrimps, the main aims of the project will be: (1) to conduct the systematic revision of available material of the genus Salmoneus (family Alpheidae) and to start their DNA analyses for phylogenetic study, (2) to finish partial phylogenetic studies of symbiotic shrimps of the family Palaemonidae focusing on the shrimps associated with marine sponges and genus complex Cuapetes - Palaemonella. In the case of studies of the dipterous insects, the aim will be especially to finish phylogenetic and DNA barcoding studies within the order Bibionomorpha (especially families Bibionidae, Cecidomyiidae). For the phylogenetic studies, the multigene analyses based on mitochondrial and nuclear markers will be used. The methods maximum likelihood and Bayesian analysis will be used for the construction of phylogenetic trees. The extensive collection available at the Department of Biology and Ecology of the University of Ostrava will be used for the systematic revision. In the case of the study of shrimps, close collaboration with specialists from museums and universities (Paris, Leiden, Taiwan) is expected, who can provide another material. In the case of study of the dipterous insects, a long-term collaboration with specialists on individual families from european (Norway, Finland, Germany) and also other countries (USA, Taiwan) is in progress. The outputs of this project will be published in scientific impact-factor journals.
