Symbioses: Plant, Animal, and Microbe Interactions

Rocha, Nicholas [1], Hernandez, Adriana [2], Specht, Chelsea [2].

Investigating pollinator preference, constancy, and diversity across the wide phenotypic range of Calochortus venustus.

Stebbins’ most effective pollinator principle suggests the coevolution of pollinators and conspicuous floral traits; that floral traits reflect the preferences of the most important pollinator to that plant. Calochortus venustus (Liliaceae) is a highly variable flower found throughout California’s Coastal, Sierra, and Transverse ranges that exhibits a wide variety of localized floral pigmentation and patterning. Little is known of the ecology and general biology of C. venustus and only one publication references the pollinators of this plant, but does not identify which pigmentations or patterns these pollinators were collected from. Because the phenotypic variation of these flowers is not due to genetic differentiation (Hernandez et al., in prep) it is possible that pollinator preferences are responsible for such variation, however such a symbiotic relationship remains uninvestigated. One reality in which pollinator preference influences C. venustus morphotypes is one where floral phenotypes are geographically limited by the range of its most important pollinators. Abundance counts and preference surveys are two methods well equipped to address this conjecture. A measure of local pollinator diversity is essential to identifying the process behind the adaptive diversification that realizes significant polymorphism within populations of C. venustus and across geographically separated populations.
