Diverzita druhového komplexu Micrasterias papillifera / M. radiosa (Desmidiales)

2016
This Master's thesis deals with diversity within the Micrasterias papillifera/ M. radiosa (Desmidiales) species complex. Both species are inhabitants of endangered biotops, like peat-bogs and, like other desmids, are used for biomonitoring. Many described varieties for both of them can be found in taxonomic literature, but their morphology is ...

Fenotypová plasticita a morfogeneze desmídií (krásivky, Desmidiales, Zygnematophyceae)

Desmids are green streptophyte algae classified in the order of Desmidiales. The cells of desmids are notable for the presence of mirror-symmetrical ornamented semicells connected by a plasmatic bridge, the isthmus. This group of organisms is characterised by a rather high ecological specificity, causing them to respond to changes in environmental ...
