Morfologická variabilita a určování terestrických forem středoevropských druhů lakušníků \kur{(Ranunculus} sect. \kur{Batrachium)}
Ranunculus sect. Batrachium is a considerably complicated group of aquatic plants. Some of the species can facultatively grow terrestrially on wet sediment surface. Due to their extensive phenotypic plasticity, they form terrestrial modificants in the terrestrial conditions. This theses deals with the Central European species that create the terrestrial modificants, namely Ranunculus aquatilis, R. baudotii, R. peltatus, R. rionii, R. trichophyllus A and R. trichophyllus B (two distinct cytotypes of Ranunculus trichophyllus). The aim of this theses is to establish whether the terrestrial forms of these species differ in their morphology. The species were determined using flow cytometry, and then morphological features were measured. Subsequently, the data were analysed using multivariate statistical methods to assess whether the terrestrial modificants can be determined.
Určování terestrických forem lakušníků (\kur{Ranunculus} sect. \kur{Batrachium})
Ranunculus sect. Batrachium is one of the most intricate groups of aquatic plants. Apart from typical submerged plants, they may grow also terrestrially and determination of the terrestrial forms is very difficult. The aim of this thesis was to establish whether the terrestrial forms of Ranunculus trichophyllus and Ranunculus peltatus differ in their morphology. The species were determined by flow cytometry and the morphological features were measured and analysed.
Interactions of the eggs and miracidia of Trichobilharzia regenti with the duck nasal mucosa
Vlčková, Linda ; Horák, Petr (advisor) ; Chanová, Marta (referee)
Trichobilharzia regenti is a nasal avian schistosome which has during the initial phase of infection an affinity to the nervous system. Larvae migrate through the central nervous system to the nasal mucosa of waterfowl, where they mature and reproduce. Until now this infection phase has been described only marginally. Adults are located in the nasal mucosa approximately from 13th to 24th day post infection. During this life phase, they migrate through the vascularized connective tissue and lay eggs, the presence of which has been detected in the tissue only. Maturation and hatching of miracidia occur in the tissue (unlike human schistosomes). The parasite causes inflammation, and the tissue is infiltrated with immune cells. Lymphocytes, granulocytes, macrophages, plasma cells and giant multi-nuclear cells were described by histological methods. The thesis is focused on a more detailed description of cellular immune response and histopathological changes of the tissue by means of histological stains, and antibody/lectin probes. The flukes were observed more frequently in the blood vessel lumen, together with a higher number of immune cells compared to the healthy duck. Infiltration by a high number of lymphocytes occurred in the tissue, the macrophages were frequently observed in clusters around the...
