Impact of seed- and microsite-limitation on species diversity in fen grasslands
The present study was set up to investigate the mechanisms limiting plant populations and species diversity in fen grasslands and to test, if management measures, proposed for fen restoration are able to overcome these limitations. As the main limitation types seed limitation and microsite- (gap-) limitation…
Hydrochory, seed availability and species diversity in riparian landscapes
Aim of the present thesis was to analyse hydrochory (dispersal by water), its partial processes and their effects on species diversity in riparian landscapes. Single steps of hydrochorous dispersal (seed transport, deposition, germination and establishment) were regarded for the colonisation of riparian…
