The influence of herbivores and neighboring plants on risk of browsing: a case study using arctic lupine ( Lupinus arcticus ) and arctic ground squirrels ( Spermophilus parryii plesius )
We examined how herbivore distribution and density, neighboring plant density and species composition, and individual plant morphology all influence the risk that individual arctic lupines (Lupinus arcticus) will be browsed by arctic ground squirrels (Spermophilus parryii plesius). Risk of being bro...
