Investigating species relationships and evolutionary patterns of defense strategies in Tricalysia (Rubiaceae).

Herbivory can act as a selective agent in evolution, shaping plant traits to optimally defend against herbivorous organisms. Further, these defensive traits can directly affect speciation and extinction rates by increasing individual fitness, giving them the potential to disperse into new areas by the acquisition of new defense strategies against herbivorous attack. The tropics provide an excellent place to study herbivory due to the increase in species diversity and interactions. Tricalysia is a genus in the Coffeeae tribe that displays a wide variety of defensive traits, including secondary metabolites, foliar domatia, foliar bacterial nodules, and colleters. The proposed research will seek to (1) create a robust phylogeny of Tricalysia using the Angiosperm353 probe set, and (2) understand how plant defensive traits have evolved in with respect to current phylogenetic hypotheses of plant defense evolution.
