Pitcher plants: From prey and parasites to pollinators (2021-02-12)

Abstract

Carnivorous plants have long fascinated biologists and laypersons because they "turn the tables," preying upon insects that might have otherwise fed on them. However, there are herbivores that specialize on carnivorous plants, and herbivory on these unique plants has not been well studied. Because carnivorous plants live in nutrient-poor habintats, and because foliar herbivory removes tissue that is responsible for both photosynthesis and nutrient acquisition, herbivory may have especially strong negative effects on growth and fitness. Floral herbivory removes tissues that are both nutrient-rich and are directly related to reproduction. I will present data on the impacts of both foliar and floral herbivory on the yellow pitcher plant.
