Lichens are characterized by the production of a large amount of secondary metabolites. Most of them are specific to these organisms. Lichenologists commonly use the metabolites to distinguish between phenotypically similar taxa. To achieve this aim, they use a plethora of detection methods, including spot reactions, chromatography, and microcrystalization tests. and Jiří Malíček.
Molekulární metody umožnily studovat šíření rostlin v povodí Labe. Druhy šířené vodou (zevar, stulík) migrují především jednosměrně podél řek. Bylo prokázáno i šíření mezi říčními systémy, častější je u druhů šířících se také větrem (rákos, orobinec). Klonální šíření mezi populacemi není u těchto studovaných druhů rostlin tak běžné, jak se dosud předpokládalo., Molecular approaches have allowed for the study of plant dispersal in the catchment area of the River Elbe. Plants dispersed by water (Bur-reed, Pond Lily) migrated mainly unidirectionally along streams. Dispersal among river systems was also detected and is more common among plants with wind dispersal (Common Reed, Cattail). Clonal dispersal does not seem to be as common in the studied species as previously suggested., and Tomáš Fér.
Czech botanists have participated in research into the taxonomy, diversity and ecology of plants in the equatorial high Andes since the mid 90s. The results include a description of new species of vascular plants and lichens, a contribution to generic flora, one monography and publication of several dozen original papers. and Petr Sklenář.
