Adaptations to novel habitats in Sarracenia purpurea

Scientists hope to understand adaptations which allow organisms to expand beyond habitats in which they originally evolved. Carnivorous plants were thought to have originated in ecosystems that are both low in nitrogen and high in sunlight. Because they are no longer limited by carbon capture due to high sunlight availability, energy can be expended into creating tissue for prey capture instead of carbon capture. This ability to capture additional nitrogen in the form of animal prey allows them to efficiently compete against plants that do not utilize prey derived nitrogen. Sarrecenia purpurea, the purple pitcher plant, is a carnivorous plant that is found primarily in the nitrogen poor bogs of the northern United States and throughout eastern Canada. Occasionally, however, this plant is found in other aquatic ecosystems, such as the interdunal swale of Grass Bay of northern Michigan. This ecosystem, unlike the common habitat of carnivorous plants, is high in nitrogen. Furthermore, S. purpurea is often found under fairly dense canopy, also contrary to the common habitat of these plants. We hope to understand the mechanism through which S. purpurea is able to exist in these atypical habitats by examining leaf morphology, green to red pigment ratios, and percentage of prey derived nitrogen between pitchers of shaded and sunny regions at Mud Lake Bog (a more typical carnivorous plant habitat) and Grass Bay. It is predicted that because S. purpurea at Grass Bay is less nitrogen limiting, shaded S.

Effects of Phenotypic Plasticity in Sarracenia purpurea L.

Sarracenia purpurea L. or the northern purple pitcher plant is a long-lived rosette-forming perennial that can be found in northern Michigan. It grows in nutrient poor environments like bogs and seepage swamps. Unlike most terrestrial plants Sarracenia pupurea L. has the ability to capture carbon and nitrogen through their leaves.

Manipulations of Water and Prey Levels within Pitcher Plants and the Effect on Inquiline Communities

Basic Information
Publication Date:

Abstract: 
The number of various inquiline invertebrates within pitchers containing either high or low levels of water volume and prey biomass was recorded. Water and prey combination treatments included high water/high prey, high water/low prey, low water/low prey, and low water/high prey.

Abstract: 
This study looks at 66 purple pitcher plants at Grass Bay, Michigan and used pitcher and habitat traits as well as stable nitrogen isotopes to determine levels of prey-derived nitrogen in pitchers and factors that correlated with nitrogen levels.
