Dew formation and aboveground biomass at the species level
In total, we measured dew formation at the species level for 10 species.
These ten species accounted for approximately 72% of the total
community biomass (Liu et al. 2018).We divided these plant species into
three functional groups, i.e., grasses (Stipa aliena, Elymus nutans and
Helictotrichon tibeticum), forbs (Tibetia himalaica, Oxytropis
ochrocephala, Medicago ruthenica, Gentiana straminea and Saussurea
pulchra), and sedges (Kobresia humilis and Carex przewalskii) and
separately analyzed their dew formation responses to warming. The
aboveground biomass was separated into grasses, sedges, and forbs,
harvested and oven-dried at 65 °C to a constant weight. Plant height was
measured using five selected individuals per species in each plot before
dew formation measurement during the experimental periods.
