Ecological Effects Of Genotypic Diversity On Community And Ecosystem Function, Megan K. Kanaga
Ecological Effects Of Genotypic Diversity On Community And Ecosystem Function, Megan K. Kanaga
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Genotypic diversity within populations can have important evolutionary consequences, but the ecological effects of intraspecific genetic variation on community and ecosystem function have only been studied in a few systems. I present the results of a three-year study designed to address the ecological impacts of genotypic diversity in quaking aspen (Populus tremuloides Michx.), using aspen genotypes planted across genotypic diversity levels (monoculture and mixture) and watering treatment levels (well-watered and water-limited). First, I demonstrated that significant variation exists among genotypes for a wide range of growth, morphological and physiological traits, and quantified high heritability and coefficient of genetic variation …
