Spatial and Temporal Heterogeneity Creates a “Brown Tide” in Root Phenology and Nutrition

Figure 2

Average crude protein content (% dry matter basis) of Hedysarum alpinum roots sampled in west-central Alberta, Canada, in different phenological stages. Error bars are 1 standard error above and below the mean. Lower case letters indicate phenophases with significantly different levels of crude protein (i.e., preleaf and flower, preleaf and seed, seed and dormant, flower and dormant).
