Description
| - Mnoho recentních studijí ukazuje positivní vztah mezi velikostí populace a její fitness. Tyto studie však neukazují důsledek tohoto vztahu pro dynamiku poplace. Studiem této otázky u druhu Scorzonera hispanica jsem ukázala, že navzdory positivnímu vztahu mezi produkcí semen a velikostí populace, vztah mezi velikostí populace a růstovou rychlostí populace není průkazný. To naznačuje, že v příštích studiích je třeba se věnovat tomuto Mnoho recentních studijí ukazuje positivní vztah mezi velikostí populace a její fitness.

- Many recent studies have demonstrated a negative effect of small Population size on single plant traits. However, not much is known about the actual consequences of reduced plant performance on the long-term prospect of species survival. I studied the effect of population size on population growth rate and survival probability in the rare perennial herb Scorzonera hispanica Occurring in fragmented grasslands. Its performance was measured using several traits related to reproduction in 21 populations ranging in size from 3 to 2475 plants. These data were then connected with data on full demography of the species front three of the studied populations. Two different matrix models differing in the number of transitions based on measurements in the populations differing in size were used to explore the relationship between population size and population growth rate. Both matrix models showed that despite the decline in seed production in small populations, population growth rate is never significantly...
