Nutrient Acquisition by Clipped Plants as a Measure of Competitive Success: The Effects of Compensation
Wallace LL and Macko SA. 1993. Nutrient Acquisition by Clipped Plants as a Measure of Competitive Success: The Effects of Compensation. Functional Ecology. 7(3):326-331
"Summary:1) Few species from the tallgrass praries exhibit compensation to herbivory while most species from the montane grasslands of Yellowstone National Park compensate for herbivory. This difference prompted the question whether plants which compensate may actually be competitively superior after herbivory. 2) Two grasses, Andropogon gerardii from the tallgrass prairie of Oklahoma and Phleum pratense from the montane grasslands of Yellowstone National Park were studied. 3) A labelled nitrogen fertilizer was applied to plants subjected to different clipping regimes. Procurement of labelled nitrogen from a distance equivalent to the species' competitive radius was equated to an active uptake of nitrogen. 4) Knowledge of the mechanism of plant response to herbivory is necessary to make predictions of competitive interactions following grazing."
