  • Coping with low-nutrient environments has led to the repeated evolution of plant carnivory. Given the repeated evolution of carnivory as well as the facultative nature of this otherwise costly trait, why are carnivorous plants not more speciose in wet, sunny, nutrient-poor sites? Recent evidence suggests herbivores may play an important role in limiting the success of plants with specialized nutrient acquisition strategies (e.g. nitrogen-fixing bacterial associates), as herbivores are drawn to more nutrient-rich plant tissue. To test this hypothesis in carnivorous plants, we conducted a factorial herbivore exclusion and prey addition experiment on Sarracenia purpurea, the purple pitcher plant. Specifically, we examined whether 1) plant growth rate is maximized at intermediate levels of prey intake, and 2) if this pattern is caused by preferential consumption by herbivores of plants with high nutrient intake. To test these hypotheses, we measured plant growth and herbivore damage on 110 pitcher plants (Sarracenia purpurea) growing at Mud Lake Bog near UMBS from June to August 2024. To measure effects of stored nutrients on plant growth and herbivory, we plan to collect 2nd year early season growth data in June of 2025.
