Aquatic ecology is a division of the science of ecology that is involved with the study of aquatic ecosystems. Other than the natural populations of organisms in the water, natural fluctuations and the effect of influences such as temperature, water depth and season, location are all form part of the study of Aquatic ecology.

Key Themes for Aquatic Ecology • The ecosystem is temporally variable tides rise and fall, floods come and go, species migrate in and out, and this variability is essential to its function. • The ecosystem is spatially variable and is dominated by several spatial gradients that are also essential to ecosystem function. • Monitoring and research help us understand the ecosystem, but our understanding will always be incomplete and will always lag behind changes in the system.
Four Aquatic Ecosystems are Freshwater and marine environments mark a primary break in aquatic ecosystems • Ponds and Lakes • Rivers and Streams • Oceans • Coral Reefs
Benefits of Aquatic Ecosystem • These ecosystems provide many important environmental benefits, to say nothing of their aesthetic and economic value. • Wetlands protect coastal areas and stream banks from flooding by absorbing excess flood waters. • Water-loving soils absorb water, acting as natural sponges.
How are the Aquatic Ecosystem Contaminated • Human Factors : Human pollution is one of the main causes of aquatic ecosystem contamination. • Red Tide : Red tide is a term used to describe a form of poisonous plankton that occurs naturally along saltwater coastlines. • Volcanoes : Volcanoes can play a role as a natural contaminant of aquatic ecosystems.
