Research in the CaraDonna Lab aims to understand the structure and function of ecological communities and species interactions, mostly with plants and pollinators. In doing so, we explore the interplay among biotic context, abiotic variation, and species’ phenologies. We ask how these factors influence plant and animal populations, their interactions, and community structure from a basic ecological perspective and under rapid anthropogenic change.

We address our research questions using a variety of approaches including: observational field studies that use existing natural variation, field and laboratory experiments that build upon knowledge of this variation, and analytical tools like network analyses and null model simulations. Our research takes place in the City of Chicago, The Colorado Rocky Mountains, and the Desert Southwest.
