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
Data from the assessment of sediment-retention ponds near Delta, Colorado, 2019
In 2019, soil samples were collected at selected sediment-retention ponds in the Gunnison Gorge National Conservation Area, near Delta, Colorado. This dataset includes pond location, pond characteristics, soil-moisture data, soil-chemistry data, and geophysical data. Pond locations were surveyed usi

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
Gunnison County Fuels Planning
Introduction: Fuels treatments have occurred within the Gunnison Basin for nearly 30 years. Since 1976, approximately 120,000 acres have been treated. Emphasis was on disposal of slash from timber sales, prescribed burning for wildlife and livestock improvements as well as restoration of threatened
