Microinvertebrate Communities Inhabiting Sarracinia Spp. Colonies In Various Habitats In Western North Carolina: Species Composition And Community Development Over Time.

Sign up or log in to save this to your schedule and see who's attending!

Sarracinia (pitcher plant) spp. provide unique spatial niches to several families of microinvertebrates and macroinvertebrates in adult and larval forms. Digestive enzymes diluted by rainfall allow for these habitats to thrive virtually free of predation. Little is known about the invertebrate composition inside pitchers, and how they develop over time during the Sarracinia spp. growing period. For three months, 8 Sarracinia spp. populations in Haywood, Buncombe and Graham county in western North Carolina were surveyed for pitcher fluid volume and invertebrate composition to provide comparative data to reveal changes over 30 day periods. Microinvertebrates populations (n) and species composition were systematically estimated from 200-600 microliter water samples from each pitcher. Data comparing three month old pitcher with four month old pitchers will reveal differences in age of microhabitat and the type and number of organisms present. Data comparing width of pitcher opening with invertebrate surveys will reveal how size of habitat will affect population numbers and diversity. Older pitchers will presumably have a higher number of microinvertebrates, and a more diverse community composition. Pitchers with a large mouth diameter will experience the same positive correlation in invertebrate count and diversity.
