Forage availability, diets, distribution, and productivity were
compared for Roosevelt elk, Cervus elaphus roosevelti, using improved
(i.e. seeded, fertilized, and grazed) and untreated areas of the Oregon
Coast Range. Seasonal forage availability was substantially different

The goals of the PO are to link (annotate) gene expression and phenotype data to plant structures and...
