Welcome to the Larkin Lab

  • Phragmites

We focus on applied challenges in plant ecology, particularly related to invasive species management, biodiversity conservation, and ecological restoration. We are interested in how plant communities respond to species invasions, anthropogenic disturbances, and other drivers of change, and how we can improve our ability to restore diverse, resilient, high-functioning ecosystems.

Our study systems include lakes, wetlands, and prairies. We use observations, synthesis, and experiments to (1) understand the contributions of plant communities to key functions, (2) investigate causes and consequences of plant species invasions, (3) evaluate the extent to which restored habitats perform desired functions, and (4) develop guidance for restoration, conservation, and invasive species management.

 Barak defense


March 2017

  • Holy cow! Mike Verhoeven received an NSF Graduate Research Fellowship! Congratulations, Mike!
  • Becky Barak will become a Smith Fellow after she defends this spring! She'll be working with Lars Brudvig and Kay Havens on Effective seed mix design for ecological restoration. Congratulations, Becky!
  • In other Becky Barak news.... her dissertation work showing that restored tallgrass prairies had lower phylogenetic diversity than remnant prairies is now out in Journal of Applied Ecology.
  • A new paper in Soil Biology and Biochemistry from Paul Hartzog's dissertation shows strong "bottle effects" during a denitrification assay---calling into question the method's reliability for assessing relative differences in denitrification potential. This research was done in collaboration with John Kelly's lab at Loyola University Chicago.

February 2017

  • A paper led by Vicky Hunt on our Phragmites invasion crowdsourcing project, PhragNet, has been published in Wetlands Ecology and Management.
  • Ranjan Muthukrishnan and Carli Wagner presented on starry stonewort research at the Midwest Aquatic Plant Management Society annual meeting. Ranjan's ecological niche modeling predicts regions of high invasion risk in Minnesota and Wisconsin. Carli's work shows high potential for reinvasion via bulbils following summer 2016 management on Lake Koronis and earned her a poster presentation award

January 2017

  • Erin Vander Stelt's work on Isoëtes butleri has been published in Aquatic Botany.
