Genetic analysis of dicyemid infrapopulations suggests sexual reproduction and host colonization by multiple individuals is common
 FLEGROVÁ, Tereza
This study explores the infrapopulation structure of Dicyema moschatum in its host Eledone moschata with the use of microsatellite markers. In order to assess the infrapopulation diversity, set of eight microsatellite markers was selected and respective oligonucleotides were designed for this population genetics study. Fragmentation method was used to analyze various microsatellite markers and the results were analyzed in bioinformatic programs that focus on standard population genetic metrics. Obtained results proved to provide new information about D. moschatum mating system and infection strategy.

Analysis of the dicyemid diversity using amplicon sequencing
 FLEGROVÁ, Tereza
Using amplicon sequencing, this study reveals dicyemid diversity around the world as well as within individual cephalopod hosts. A wide number of samples of multiple species were collected to reflect true dicyemid diversity. Heterogeneity primers were designed in order to improve the sequencing performance of the Illumina platform. A complex bioinformatic pipeline was implemented to process non-overlapping reads. The species delimitation methods were used to categorize occurring dicyemid types. Using the output of implemented methods, dicyemid diversity was assessed, proposing new trends opposing the current methodology.

Evolution and Phylogeny of Mesozoa
 DRÁBKOVÁ, Marie
This thesis focuses on the phylogenetic position of Mesozoa (Orthonectida and Dicyemida) based on phylogenomics, and on dicyemid life-history traits revealed by molecular methods used in population genetics. The thesis is introduced by the review of biology of both groups, complemented by up to now development of views on their phylogenetic position and notes concerning the study of the population structure of marine invertebrates. The introduction is followed by a study focusing on the phylogenetic position of Mesozoa, a comparison of population structure between the cephalopod host and its dicyemid parasite, and a case study of dicyemid parasite infrapopulation. The thesis wraps up with a review on cephalopod parasites and a summary.
