Figure 1From: Smoke-Cued Emergence in Plant Species of Ponderosa Pine Forests: Contrasting Greenhouse and Field ResultsMean density and species richness of emergents from 0 cm to 5 cm soil seed bank samples either untreated or treated with aqueous smoke. Means within (a) and (b) differed significantly (P < 0.05), with error bars representing 1 SD. Samples were collected from nine sites in ponderosa pine forests, northern Arizona.Back to article page
