Abstract

In this study, we performed several transect surveys over the course of the 2021 summer field season to assess potential ecogeographical range determinants for Lewis flax (Linum lewisii) and its pathogen, flax rust (Melamspora lini), in the area surrounding the Rocky Mountain Biological Laboratory in Gothic, Colorado. Additionally, we used generalized additive models to examine the effects of host population density and metapopulation structure on disease presence and prevalence.
