A pathogen’s spatial range is not constrained by geographical features in the flax rust pathosystem

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.

本研究于2021年夏季野外考察季期间开展了多次样带调查，旨在评估科罗拉多州哥特镇落基山生物实验室（Rocky Mountain Biological Laboratory）周边区域内，刘易斯亚麻（Linum lewisii）及其病原菌亚麻锈菌（Melamspora lini）的潜在生态地理分布决定因子。此外，本研究采用广义可加模型（generalized additive models），分析了寄主种群密度与集合种群结构对病害发生及流行率的影响。
