The effects of ungulate herbivory and nutrient variation on pollen reciept in Ipomopsis aggregata
The purpose of this study was to investigate the effects of ungulate herbivory (clipped, unclipped) and nutrient variation (ambient, water added, fertilizer and water added) on conspecific and heterospecific pollen receipt to Ipomopsis aggregata. I found that both clipping and adding nutrients influ
Does Floral Nectar Depth Correlate With Pollinator Proboscis Length?
Pollination is essential for maintaining global biodiversity and our world’s food supply. Climate change is causing inefficiencies in plant-pollinator networks, so understanding the factors that determine which pollinators visit which plants will be exceedingly important for a sustainable future.

Frenemies: conflict and cooperation in burying beetle (<i>Nicrophorus investigator</i>) parental care
Conflict and cooperation can drive how unrelated individuals interact, while illustrating whether the interests of two individuals converge or diverge. The subsocial, biparental beetle Nicrophorus investigator provides an excellent model to study these two interactions because researchers can manipu
Factors that affect the repeatability of personality in yellow-bellied marmots, <i>Marmota flaviventris</i>
Animal personality is becoming increasingly relevant behavioral ecology because of its potential impact on reproductive success. Measuring personality however can be difficult because many factors, such as microhabitat variation and habituation, affect how an animal responds to a given test. Using n
Axenic culture of two new species of branched Trichomyctes
Two new endocommensal fungi belonging to the Genistellaceae (Harpellales) were isolated in pure culture from the hindguts of Diptera larvae: Smittium culesitae from the mosquito Culesita impatiens, on a 10% brain‐heart infusion, and S. simulii from the black fly Simulium argus, on a potato dextrose‐

Effects of water availability on expression of vegetative traits in Ipomopsis across space and time
In subalpine ecosystems, climate change has contributed to an earlier snowmelt as a result of warmer temperatures in the winter and spring. This shift may act to limit water availability for plant communities by prolonging the period between initial snowmelt and late-season monsoon rains, placing th

Testing the oviposition cues that drive preference of <i></i>Hylemya<i></i> for different sexes of <i></i>Polemonium foliosissimum<i></i>
This investigation focused on how mutualists and antagonists affect the flowers of different sexes within the same species. My study examined plant and insect interactions in Polemonium foliosissimum to better understand the selective pressures that influenced the evolution of gynodioecy in this pla

The effects of elevation on flower abundance and pollinator visits on Helianthella quinquenervis
Spatial-temporal variation in pollinator populations can have an impact in plant reproduction. This study assessed the effects of elevation on flower abundance, pollinator visitation, and types of pollinators visiting the Helianthella quinquenervis This flower species was chosen due to its vast abun
