Cariveau Lab Team
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.
Extension and Research
Research interests: I work on questions related to wild bee diversity and bee conservation. I am currently assessing the status of Minnesota wild bee communities in comparison to historic records as well as monitoring population of the endangered rusty-patched bumble bee and examining habitat associations.
Outreach and education: I work on bee citizen science efforts including the Minnesota Bee Atlas and the Minnesota Bumble Bee Survey. I also work on education efforts to increase awareness of wild bee habitat needs and instill action to create effective pollinator habitat.

BS, Biology, 1993, Evergreen State College, Olympia WA
Books: Befriending Bumble Bees, Managing Alternative Pollinators
Research interests: I am a bee taxonomist, broadly interested in the evolution, ecology, and conservation of bees. My PhD work focused largely on the genus Perdita (Andrenidae). I am currently working on the regional taxonomy of Minnesota bees.

I am a Research Scientist at UMN working on three different stem and wood nesting wild bee projects. I have my Masters in Biology from the University of South Dakota studying the endangered Hine's emerald dragonfly. My undergraduate was in Biology from Cornell University. Between schooling I really enjoyed radio-tracking re-introduced whooping cranes and recording vocalizations of wild ones. I've worked at UMN since 2009, first as a research coordinator for the entomology portion of a study on using restored grasslands for both bioenergy and wildlife habitat. My three current projects are: 1. Native grassland plants used as nesting sites for wild bees, 2. Minnesota Bee Atlas-a citizen science project. 3. Minnesota Futures Grant called The Art and Science of Nesting Bees. My academic interests include ecology, grasslands, wild bees, and discovering the natural history and life cycles of stem nesting bees in particular. When not thinking about bees, I enjoy spending time with my husband, dog and two daughters, being outside, going to lots of playgrounds and parks.
Current Graduate Students
I’m a M.S. student in the entomology program. I joined the bee lab in 2017. I am interested broadly in pollinator conservation, more specifically in assessing bumblebee communities along roadsides and in managed parks. I’ve always been passionate about conservation and am very excited to be part of such an amazing team of researchers!
BS, Biology, 2016, University of St. Thomas, St. Paul, MN
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.

BS, Crop and Soil Sciences, with a minor in entomology and a specialization in sustainable food systems, 2012, Michigan State University
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.

I am interested in native bee populations as they relate to natural and agricultural lands. I want to better understand plant and bee community interactions and how to best manage multifunctional landscapes.
I am working with the National Park Service to understand the influence of invasive plant management, specifically buckthorn removal, on wild pollinator populations.

Christina joined the bee lab in February 2017 to help with projects studying wild bee communities and native plant pollination in prairie reconstructions around western Minnesota. She manages logistics including hiring technicians, developing protocols, and purchasing and maintaining supplies and equipment to ensure a successful field season. She also helps lead the field crew during summer.
Christina earned a B.A. from St. Olaf College in 2012 and an M.S. in Land Resources and Environmental Sciences from Montana State University in 2014. Her master's project involved studying the invasive plant spotted knapweed and its interactions with insects, including pollinators. Christina is passionate about applying science and research to improve conservation practices.
Research interests: I am interested in the nesting behavior of wild bees. From 2015-2016, I participated in a study that used natural trap-nests in order to determine the habitat requirements of native stem-nesting bees around Minnesota. I am currently running a project sampling bees from local community and vegetable gardens. I think that public education and strong local communities are crucial to conservation efforts.

Michelle started at the Bee Lab in 2014 as an Undergraduate Research Assistant and currently works as a Research Scientist.
Native Bee Lab: As an undergraduate she worked on a wild bee historical comparison study. Body lengths of current and historic bees were compared to see if overall bee sizes were changing over time with changes in landscape. She is passionate about wild bees and finding ways to conserve and improve their habitat. https://conservancy.umn.edu/handle/11299/187700
Honey Bee Lab: She has collected resin from honey bees, extracted RNA to make cDNA copies for real time PCR analysis and other field and laboratory work. She is currently decoding waggle dances and recovering pollen from honey bees via acetolysis. Michelle is interested in finding ways to improve honey bee health through research.
