How to reduce scientific footprint? The climate changes have contributed to the continously growing interest for field research in Eastern Svalbard. In many research fields, the knowledge about East Svalbard is extremely limited and therefore data is needed first before it is possible to establish a baseline for future reference. To affect reference area as less as possible, data collection should leave small size footprint on environment (e.g. using advanced, non-intrusive technology, several groups working in field together in coordinated and synchronized manner).
Parazitické rostliny představují velmi specifickou skupinu v rámci rostlinné říše, jejíž zástupci jsou jinak autotrofní. V průběhu evoluce vynalezly tyto rostliny mnoho způsobů parazitismu na zdrojích, strukturách a službách, ve kterých využívají jiných rostlin, hub nebo dokonce živočichů. V článku jsou definovány jednotlivé funkční skupiny parazitických rostlin a stručně popsána jejich biologie. and Parasitic plants present a very specific group among otherwise autotrophic representatives of the plant kingdom. During evolution, these plants invented different ways of parasitism on resources, structures and services, exploiting other plants, fungi and even animals. Individual functional groups of parasitic plants together with their biology are described in the article.
