| Abstract: | All vascular plants, classified by life and growth form into aquatic species (hydrophytes and helophytes) and terrestrial species of pond margins, were inventoried in 64 SE Norwegian agricultural landscape ponds and their adjacent margins for which also 56 explanatory variables were recorded. Gradients in species composition, found separately for aquatic and terrestrial species by parallel DCA and GNMDS ordinations, were interpreted by correlation and geostatistical analyses. |
