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 2022. The censuses took place in ten L. porteri populations near

Plant reproduction and optimal foraging: experimental nectar manipulations in Delphinium nelsonii
Delphinium nelsonii Greene (Ranunculaceae) individuals which were watered produced significantly more nectar per flower than did control individuals. The watered plants also set significantly more seeds per flower than did the controls. Hand pollinations suggest that the seed set difference was due
Calculating nectar production rates: residual nectar and optimal foraging
The fact that residual nectar exists is consistent with predictions of optimal foraging theory but more detailed work is necessary before it can be concluded that the volumes left behind in A. columbianum flowers are optimal.
