Multi-year census of arthropod abundance on the plant Ligusticum porteri near Gothic, CO

The purpose of this study was to track year-to-year variation in aphid abundance on the host plant Ligusticum porteri (Apiaceae). We censused arthropod abundance on the flowering stalks of L. porteri weekly in June-August from 2012 to 2020. The censuses took place in ten L. porteri populations near

An investigation into the effects of arbuscular mycorrhizal fungi (AMF) to dark septate endophytes (DSE) ratio on the coarse root to fine root ratio at varying elevation in the rocky mountains

Belowground systems are crucial for sustaining ecosystem function, but often remain unseen. Not very much is known about these systems and improving knowledge of them can aid understanding of ecosystems. Elevational gradients can be good places to test how above- and belowground systems respond to c
