| Description
| - Byl studován obrat populací jednoletek rostoucích na mraveništích Lasius flavus. Předpokládalo se, že pokud bude (re) kolonizace stanoviště uskutečňována pomocí diaspor šířených z okolních populací, pak bude záviset na jeho prostoré konfiguraci. Pokud se však toto děje pomocí vytrvalé semenné banky, prostorové uspořádání ztrácí na významu. Počítačová simulace prokázala jako daleko výzmnější zdroj semennou banku, avšak analýza obratu v terénu zjistila signifikantní prostorové závislosti a tím také význam prostorem šířených semen. Tento rozdíl je diskutován. (cs)
- In patchy-distributed plants with persistent soil seed bank, vacated patch can be (re)colonized by means of diaspores spreading from neihgboring populations, and/or by seeds from the soil. If the latter source is more important for (re)colonisation, then spatial configulation of patches is of little importance. I analysed turnover dynamics of 5 annual species growing on ant-mounds over three years. Based on the knowledge of dispersal and seed survival capacity, I assesed the importance of each seed source for population (re)colonization. Seeds persisting in the soil were determined in the simulation to be much more important than seeds spreading from other populations. Nevertheless, analysis of observed turnover pattern clearly proved significance of spatial configuration and thus also importance of seeds spreading from neighhboring populations. Discrepancy between expected and observed pattern is discussed.
