Study Notes
Coastal Ecosystems and Environmental Factors
- Zones of maximum turbidity concentrate nutrients and suspended sediment, supporting rapid plankton growth and a rich biological community.
- Pycnocline is a layer that separates high-density saltwater from low-density saltwater.
- The Redfield Ratio sums up the essential nutrients for plant life in the bay, including carbon, nitrogen, and phosphorus.
- Diatoms are single-celled algae with glass-like walls, providing essential food for primary consumers.
- Dinoflagellates, green-blue algae, predominate in the summer, while diatoms are more abundant in the winter.
- Intertidal ecosystems are above water at low tide and underwater at high tide, while subtidal ecosystems are always submerged.
- Epifauna, such as crabs and snails, travel over the flat to feed on plant debris and invertebrates on the mud surface.
- Infauna, including deposit-feeders and meiofauna, live below the mud surface, providing a food source for other organisms.
- Sessile organisms are fixed in one place and do not move.
- Detritus refers to dead or decaying organic matter that accumulates in ecosystems, such as dead plant material in the marsh ecosystem.
- Phytoplankton are autotrophic components of the plankton community, while zooplankton are a type of heterotrophic plankton.
- Living shorelines are a natural approach to erosion control that preserves the coastal edge by planting vegetation and using other natural materials.
