Grapevine chloroplast (cp) DNA diversity was analysed for the first time through amplification and digestion of fragments of the large single copy (LSC) region by polymerase chain reaction-restriction fragment length polymorphism methodology and also by amplification of three microsatellite loci, previously described as polymorphic in grapevine. Thirty-eight grapevine cultivars collected mainly...

Previous in situ studies of orchid population dynamics with conservation relevance have focused on one or a few populations in a limited area. Many species of orchids occur as hyperdispersed populations in ephemeral habitats (epiphytic, twig epiphytes, short lived or vulnerable host). In this contribution, we show that orchid populations that are patchily distributed and that exist in disturban...

The paper discusses various aspects of biosorption of microelements by marine seaweeds to be used as mineral feed supplement for livestock. n the study, biosorptive properties of a single marine species Cladophora rupestris and mixed species of algae from the Baltic Sea (a mixture f Cladophora sp. and Enteromorpha prolifera) were investigated. The mechanism of biosorption was identified as cati...
