My research aims to understand how plant populations and communities respond to global change. It spans population modeling from orchids to old growth trees, uses meta-analysis to forecast biological impacts of climate change, and leverages citizen science data to aid global change research. I have worked in diverse systems, and am compelled to study anthropogenic impacts because humans exert a large and growing influence on Earth's biota, and because I believe we can simultaneously learn about basic ecology and address applied problems in natural resource management.

I study the ways organisms are affected by heterogeneous landscapes, with a focus on the movement and demography of Lepidoptera. Recently my work has focused on the Fender's blue butterfly (Plebejus icarioides fenderi), an endangered species found in the Willamette Valley of Oregon and the frosted elfin (Callophrys irus) in Massachusetts. In the past, I primarily worked with temperate fruit feeding Nymphalid butterflies, studying their movement in fragmented landscapes and the environmental cues they use to make movement decisions.


Graduate Students

Natalie Kerr
My research interests involve using population models to evaluate life history strategies and trade-offs in insects. More specifically, I am currently investigating size variation in bumble bees (Bombus vosnesenskii) as well as delineating age-based differences between the invasive cabbage white butterfly (Pieris rapae) and its native counterpart, the mustard white butterfly (Pieris oleracea). I am third-year Ph.D. student who graduated from the University of Queensland with bachelor of Environmental Science with first class honours majoring in Natural Resources Science.

Genevieve Pugesek
I am a second year graduate student in the Crone lab. My aspiration is to conduct impactful research and advocate change in conservation strategy. I am broadly interested in community ecology and conservation genetics as they relate to agroecosystems. I am particularly interested in pollinators, as the ecosystem services they provide are significant to both ecological and agricultural systems. After completing my Ph.D. studies, I would like to conduct research centered on the establishment of populations of feral organisms and their impact on ecological communities. Though underappreciated, understanding the impacts of this ongoing change is relevant to conservation of biodiversity.

I am interested in the genetics of rapid divergent evolution. My rotation project with the Crone lab is on mathematically modeling the population dynamics of the European corn borer resulting from phenological differences across the latitude and among genotypes.

Kirsi Alahuhta
I am a graduate student in ecology at the University of Oulu, Finland, and I am working together with Dr. Crone to model the population dynamics of plant species with prolonged dormancy. Since true fate of a plant that does not sprout is unknown (dormant or dead), researchers have been forced to make simplifying assumptions when estimating survival of such plants. I studied, both analytically and empirically, how these assumptions affect the projections of matrix population models for two orchids, Isotria medeoloides and Epipactis atrorubens. In the future I would like to expand my theoretical research to variety of ecological systems.

Michał Bogdziewicz
I am broadly interested in ecology and evolution of mast seeding, as well as its trophic consequences. Recently, we showed that anthropogenic emission of nitrogen is likely to reduce reproduction of masting trees despite driving increase in seed production. This is caused by indirect alternations in interactions of oaks with acorn consumers. I received my M.S. in ecology at Adam Mickiewicz University in Poland, and am a fourth-year Ph.D. student co-supervised by Dr. Rafał Zwolak and Dr. Elizabeth Crone.

I help with whatever needs helping. I recently graduated from Tufts University and completed a senior honors thesis in the Crone lab on bumble bee population dynamics.
