Lack of lake augmentation effects on aquatic macrophyte abundance and distribution in west-central Florida lakes, USA

摘要: This study tested the hypothesis that lake augmentation with well water impacts distribution and abundance of aquatic plants in lakes. Water chemistry was measured from 14 wells, augmented lakes, lakes without augmentation. Nine in-lake macrophyte species metrics were all Net photosynthetic rate (NPR) nine submersed also water. Augmentation increased alkalinity receiving but total phosphorus significantly lower, which resulted lower chlorophyll greater Secchi depths. Although NPR higher for incubated water, only one (emergent richness) metric different Lake changed waters, effects on macrophytes minimal, suggesting other environmental factors are limiting The levels unexpected because concentrations than or Precipitation calcium phosphate likely accounts reduced
