Abstract
Copepods are the most diverse and abundant groups in aquatic ecosystems and also dominate in polar ecosystem. Despite of their abundance and vast diversity, few complete mitochondrial genome data have been reported so far. Mitochondrial genomes contain the most informative sequences and gene arrangement for deeper phylogenetic analyses and they reflect evolutionary relationships and biogeography in the metazonas. In an attempt to get more mt genome data of polar organisms, we selected two calanoid copepod species; Boeckella poppei and Calanus hyperboreus. Boeckella poppei and C. hyperboreus are considered being endemic species in Antarctic and Arctic, respectively. In our result, the gene arrangement of C. hyperboreus is very distinctive comparable to the pan- crustacean ground pattern. The interaction between adaptation in the harsh environment and mt genome rearrangement has been postulated in several studies. Therefore, we attempted to compare mt genome of Arctic C. hyperboreus with non-polar habiting Calanus sinicus previously published. Also, we compared mitochondrial genomes between Arctic C. hyperboreus and Antarctic B. poppei to investigate the possible correlation between environment and mitogenomic features. We attempt to solve the ordinal relationships of copepods in Subphylum Crustacea by phylogenetic analyses using sequence data from mitochondrial protein-coding genes. genomes contain the most informative sequences and gene arrangement for deeper phylogenetic analyses and they reflect evolutionary relationships and biogeography in the metazonas.
