摘要: In experimentally heated plots that each span a soil moisture gradient in Rocky Mountain meadow, aboveground biomass of Artemisia tridentata (a sagebrush) increased the drier habitat and Pentaphylloides floribunda shrub cinquefoil) wetter relative to control plots. contrast, forb decreased wet dry habitats These results, combined with evidence for enhanced sagebrush seedling establishment rates plots, suggest warming expected under an atmosphere concentration carbon dioxide twice pre-industrial levels could change dominant vegetation widespread meadow habitat.
