Aquatic Biomes

Streams and Rivers

Freshwater ecosystems with flowing water, characterized by <1% salt concentration and fast-moving waters, supporting diverse aquatic life.

Salinity Type

Indicates the salt concentration in water; freshwater has <1% salt concentration.

Riparian habitat

Areas adjacent to rivers or streams that support diverse wildlife due to rich ecosystems.

Oligotrophic

A type of water body with low nutrient levels, typically clear but can support wildlife.

Mesotrophic

A water body with moderate nutrient levels between oligotrophic and eutrophic.

Eutrophic

A water body with high nutrient levels, often leading to algal blooms and low oxygen.

Wetlands

Lowland areas that are saturated with water at least part of the year, providing essential ecosystem services.

Essential Ecosystem Services in Wetlands

Includes flood control and water filtration, supporting biodiversity.

Estuaries

Where freshwater meets saltwater, characterized by variable salinity and high productivity.

Mangrove forests

Coastal ecosystems that protect shorelines from erosion and provide habitat for diverse species.

Coastal/Intertidal zones

Marine regions affected by daily tides, with specific adaptations for organisms to survive.

Coral Reef

A marine ecosystem characterized by a symbiotic relationship between corals and algae, known for its biodiversity.

Coral bleaching

A phenomenon where corals lose their color due to stress from factors like pollution and temperature changes.

Open Ocean

Marine areas where waters are mixed by currents, supporting phytoplankton in photic zones.

Threats to Freshwater Ecosystems

Include diversion, dams, channeling, pollution, and development.

Threats to Coral Reefs

Sediment pollution, warmer temperatures, and high nutrient loads that lead to coral stress.
