  • Phylogenetic divergence within Pelagiidae
    Ramšak, Andreja, 1966- ; Stanković, David
    Scyphozoan taxa are particular due to complex life cycle, ecological plasticity, unpredictable appearances and thus taxa rearrangements are common. A cladistics analysis revealed re-description of ... many taxa within Pelagiidae family and recently, a new genus Mawia benovici was included into family Pelagiidae. Moreover, phylogeographic inference used for substantial rearrangements of the genera within this scyphozoan family leading towards more consistent evolutionary relationships. Even though, many of phylogeographic studies on scyphozoan jellyfish do not estimate dates of evolutionary events, because the time of origin is still elusive, due to a lack of calibrated substitution rates. In this study, we calculated molecular clock and estimated the time of origin of Mawia benovici. Phylogenetic tree for COI, 12S, 16S, 28S, ITS1 and ITS 2 was reconstructed using Maximum Likelihood with RaxML v. 8.2.8, while molecular clock analysis was done using Bayesian inference (BI) with BEAST v. 1.8.3. Both ML and BI approach were conducted on partitioned dataset using Cyanea capillata as an outgroup. Finally, we used TreeAnnotator to calculate a maximum clade credibility tree, median values of divergence times, posterior probabilities, and bounds for the 95% highest posterior density (HPD) interval.
