Estuaries

by: Vitoria Ferrara

Description

  • An estuary is where saltwater and fresh water mix. Many animals rely on these estuaries for food, breeding, and rest areas. Estuaries are also one of the world largest productive ecosystems, they contain many nutrients from the land and sea.
  • Estuaries can be found on the coast by oceans and seas.
  • can be known as lagoons or harbors
  • Examples: San Fransisco Bay, Chesapeake Bay, and the Galveston Bay

Abiotic and Biotic Factors

  • Some abiotic factors may include temperature, salinity (saltiness), sunlight, soil, and waves.

  • Some biotic factors may include habitats for wildlife (birds, fish, otters, seals), plants, and humans. Plants and animals that can stand a large amount of salinity are called euryhaline.
  • An example of a plant community that is euryhaline is the Pickleweed, and an example of a euryhaline animal most found in estuaries are blue crabs.

Importance

Estuaries filter nutrients from surrounding bodies of water, this makes them the most fertile ecosystems. Estuaries also keep coastal shores, and streams from eroding, which can be caused by wind, water and ice. They do this by soaking up the excess water like a sponge.

Human Impact

humans are causing habitat destructions in estuaries which is leading to fishery decline, and the overall estuarine health. (salinity increasing)
