Principal Investigator

Alex Field No Border

Alexandra Harmon-Threatt, Ph.D. 

Dr. Harmon-Threatt is broadly interested in asking ecological questions with conservation implications. This has included questions such as: Do the breeding systems of invasive plants differ from close native relatives? Do pollinators prefer higher quality plant resources regardless of origin? How do invasive plants set seed? Do bees make preference decisions based on nutrition?This has included assessing the effects of invasive plant species on preference, nutritional analysis of plants

Graduate Students

Nick Anderson 

Nick joined our lab in June 2014 and is working on understanding how chronic exposure to neonicotinoids might affect bee survival, fecundity, and behavior.





Scott Clem

Scott joined the lab in the fall of 2016 as a PhD student. He received his bachelor’s degree in zoology with a minor in entomology in 2012, and a master’s degree in entomology in 2015 from Auburn University. He is currently interested in investigating the overwintering and dispersal/migratory dynamics of hoverflies (Family Syrphidae).  These are lesser-known pollinators that often mimic of bees and wasps.  While the adults are important pollinators, the larvae are voracious predators of soft-bodied arthropod pests like aphids.


Jon Tetlie

Jon joined the lab in the summer of 2017 and is currently developing a project focused on the behavior of female ground nesting bees particularly in regards to agricultural neonicotinoid input residues found in the soil of both agricultural fields and bordering natural habitats.



Lab Assistant

Katie Barie 

Katie joined the lab in the winter of 2017 working on the bee diversity and movement project in the Missouri glades.
