Description
| - V druhově bohaté louce (53-65 druhů cévnatých rostlin na ploše 1,1 m2) byl studován význam nedostatku diaspor, způsobený jejich omezeným šířením, u náhodně vysetých plevelů. Přestože ani jeden z vysetých druhů se přirozeně na lokalitě nevyskytuje, 5 druhů se na ploše uchytilo. Jeden z nich přežíval po 7 let, ovšem jeho početnost klesla z 41 rostlin zaznamenaných v roce 1995 na 1 rostlinu v roce 2001. Tato data mohou být interpretována jako důkaz krátkodobé limitace diasporami. Dlouhodobý pohled však naznačuje, že tato data lze interpretovat i přesně opačně. Uchycení plevelů bylo pravděpodobnější v ploškách s nižším počtem druhů a jedinců, což znamená, že již přítomné rostliny ovlivňují generativní regeneraci. (cs)
- Dispersal limitation was studied in a species-rich meadow (53-65 species of vascular plants per 1.1 m2) to which a mixture of weeds was accidentally sown. Even if none of the sown species belonged to the local species pool, five species successfully established. Of them one persisted for 7 years, however declined from 41 individuals in 1995 to 1 individual recorded in 2001. These results can be interpreted as an evidence for short-term diaspore limitation. In contrast, long-term data indicate no diaspore limitation. Establishment of weeds in subplots with a lower number of species and individuals was higher than in other subplots, indicating that plant establishment in the studied open-canopy grassland is affected by the spatial pattern of present plants.
