Sexual reproduction in Arctic and subarctic flowering plants is often overlooked, but has important ecological and evolutionary consequences. Berry and other fruit production for many species in Alaska requires the movement of pollen by pollinating insects from one plant to another. Changes in the composition and structure of plant communities due to invasive plant establishment and changes in the dominance of native species are likely affecting plant reproductive ecology in diverse ways in the state. Our research focuses on pollen limitation of fruit and seed production in tundra systems, plant reproductive interactions, pollinator-mediated selection on floral traits, and insect pollinator community composition.
We collaborate with a number of researchers from other institutions including: Christa Mulder, Katie Spellman, Justen Whittall, Courtney Amundson, Steve Gisler, Loriel Caverly, and Jessica Schneider.
