My lab addresses questions in nutritional ecology, a field at the intersection of behavioral ecology, environmental physiology, and molecular biology. Specifically, we study nutritional ecology in insect pollinators to investigate three broad questions. See Goings-on for our most recent projects/updates!
How do organisms identify supplemental nutritional resources?
Insect pollinators get most of their nutrients from flowers–pollen provides protein and fats, nectar provides carbohydrates, and both provide trace amounts of vitamins and minerals. But sometimes, insects visit non-floral resources to supplement their floral diet. My past research shows that honey bees visit “dirty” water sources as a way to supplement the minerals in their floral diet and stingless bees visit carrion (or raw chicken). In my lab, we investigate which non-floral sources insect pollinators use, when/how they use them, and what this means for pollinator health in a changing environment.
How does nutrition affect multi-species interactions?
Insect pollinators interact with many species of plants but there’s another species interaction that sometimes gets overlooked: myrmecophily, or caterpillars that love ants.
As caterpillars, Lycaenid butterflies interact with ants. When threatened, caterpillars signal ants for help using scent or sound. When the threat has passed, caterpillars reward ants by exuding a sugar droplet. My lab examines the role of nutrition in this symbiosis. Caterpillar nutrition may affect the nutritional value of the sugar reward, and thus affect ant-tending behavior and caterpillar survival.
How does nutrition affect disease response?
It’s no secret that many of our native insect pollinator populations are in decline and it’s harder to manage honey bee colonies than ever before. While there are likely multiple factors at play (land use change, use of pesticides, climate change etc.), my lab is interested in how nutrition affects honey bee response to disease. If insect pollinators are able to get a well-rounded diet, they will likely be better equipped to deal with various stressors.
As social insects, honey bees are also an interesting system to investigate how nutrition affects a common cost living in a large group: disease spread.
Undergraduates are using satellite imagery to determine suitability of local sites for studying the rare butterfly, the frosted elfin. Soon, we will visit the most suitable sites and search for butterflies!
Undergraduates are surveying campus and our two natively planted BioSwales to determine on-campus pollinator diversity and which wetland plants might be “best” for pollinators
Continuing from my post-doc work in the Pacific Northwest, I am working on data analysis to determine how a changing climate might affect butterfly flight season as well as availability of nectar and host plants (both nutritionally important!).
