Research Interests: We are studying fungi as part of the much larger FIBR effort that examines the genetic basis for community and ecosystem ecology of cottonwoods, a critically important riparian tree. We are investigating the relationship between the diversity and community composition of arbuscular mycorrhizal, ectomycorrhizal, and endophytic fungi within and between species of hybridizing cottonwoods. Our studies involve field and common garden sampling as well as culturing and molecular genetic assays of fungal communities in roots, stems and soil. We complement these community assessments with greenhouse experiments to link structure with function. Current personnel involved: J. Lamit, Z. Kovacs, B. Ji and K. Meinhardt. Links to litter and belowground fauna (microarthropods and nematodes) are being explored by T. Wotjowicz.
