Biosystematic studies in the family Cyperaceae
KOŠNAR, Jan
The thesis was focused on the microevolutionary mechanisms that contribute to morphological diversity in selected members of the sedge family (Cyperaceae). Natural hybridization, evidenced from both morphological characters and molecular markers, was revealed to be a potentially important source of diversification in the tropical spikerushes of Eleocharis subgenus Limnochloa. High levels of phenotypic plasticity of clonal growth but rare genetic (ecotypic) differentiation among contrasting morphotypes were found in the polymorphic species Carex nigra, which implied that taxonomic splitting of the species was unreasonable.
Plant Rhizodeposition and Rhizosphere Microflora: Their Relationship and Its Consequences in Wetlands
KUBEŠOVÁ, Jaroslava
Annotation: Plant and microbial relationships in the rhizosphere have been briefly reviewed. The research of tropical wetland ecosystem in northern Belize has been summarized. After that a synthesis of both parts results in the hypothesis of carbon, nitrogen and phosphorus flows between Eleocharis cellulosa, Typha domingensis and their rhizosphere.
