The effects of management and environmental variation on population stage structure in three river-corridor violets

Original language description

Population stage structure of plants, i.e. the density and frequency of individuals in different stages of the life-cycle, is a crucial aspect of population viability that depends on a variety of factors. In this paper, we evaluated the effects of (i) management and year, (ii) location (population) and time (year) and (iii) of local habitat quality and population factors on population stage structure of three morphologically similar, closely related violets from floodplains, Viola elatior, V. pumila andV. stagnina. We hypothesized that owing to similar life-cycles there should be no significant differences in population stage structure among species. We analysed population stage structure in managed vs. abandoned population to test whether a proposedeffect of management acts through the creation of regeneration niches. We further tried to identify which habitat factors are responsible for possible management effects. We established permanent plots (0.25 m2) in 27 populations of the s

Vliv managementu a faktorů prostředí na populační strukturu tří druhů violek říčních úvalů

Czech description

Struktura populací rostlin, tj. hustota a frekvence jedinců různých stadií životního cyklu, je klíčová pro životaschopnost populací, která zavisí na mnohých faktorech. Hodnotili jsme (1) vliv managementu a roku, (2) vliv lolity (populace) a času (rok) a(3) vliv kvality habitatu a populačních faktorů na zastoupení jednotlivých stadií tří podobných blízce příbuzných violek Viola elatior, V. pumila and V. stagnina.
