Meet the Cariveau Native Bee Lab

Daniel Cariveau
Assistant Professor

Dan is a community ecologist with an interest in understanding the factors that drive biodiversity and how biodiversity may influence ecosystem function. His work focuses on native bee communities with a strong emphasis on pollination ecology. Most recently, his work focuses on restoration ecology as a way to conserve biodiversity and as a tool for examining basic questions in ecology.

He earned his PhD studying the interaction among plants through pollinators at Colorado State University under Dr. Andrew Norton. He then studied native bee community ecology and the role of native bees in crop pollination as a postdoctoral research associate at Rutgers University with Dr. Rachael Winfree. Dan joined the Department of Entomology at the University of Minnesota as an Assistant Professor in September 2015.

Research interests: I am broadly interested in questions related to
bee community assembly and the role of restorations in conserving bee

Project: I am currently pursuing questions related to how bee
community composition in both prairie reconstructions and remnants
change as sites become increasingly isolated from other natural
habitats. I am also interested in how species specific floral
specialization might explain bee community structure within
reconstructed prairies along this gradient of isolation.

Research Interests: I am interested in plant-pollinator interactions, specifically how behavioral and morphological traits affect pollinator performance.


Project: Currently I am examining pollen limitation and its potential mechanisms in early restored prairies. Simultaneously, I'll be determining the most effective native bee pollinators of focal prairie plant species. I'm also interested in how the pollinator assemblages and degree of pollen limitation of focal plant species differ between restored and remnant prairies.
