Introduction to Estuarine Ecosystems

  • Definitions and ecosystem diversity
    • Estuaries: Areas where freshwater from rivers meets saltwater from the ocean, creating unique ecosystems.
    • Communities within estuaries vary significantly based on salinity and hydrology.

Examination of Specific Marsh Examples

  • Purple Flower: Pickerel Weed
    • Abundant in low saline conditions along stream banks and in lakes.
    • Historically consumed by Native Americans and used to produce tea.
  • Examples from Virginia and North Carolina
    • Floating marsh presentations of species distribution and ecological dynamics.
    • Transition zones from marshes to woody vegetation, with species such as sycamores, willows, and cypress trees.
    • Influence of hydrologic conditions on plant composition and community structure.
