Freshwater ecology concerns the relationship of organisms to their environment in aquatic ecosystems, or lakes, rivers, streams, and ponds, as well as in wetlands. This area of study is critical in understanding biodiversity, ecosystem services, and impacts of environmental changes on aquatic habitats.

Freshwater ecosystems are extremely diverse. Organisms present here range from microscopic plankton to the large fish and amphibians. Knowing the dynamics in freshwater ecology better will help societies manage and conserve those providers of critical services like water purification, flood regulation, etc., ecosystems.

Biotic interactions, that is predators, competitors, and symbionts, are a very robust feature of freshwater ecology. Biotic influences basically structure communities and act to determine species distribution and abundance. For example, predation by fish might control populations of other small organisms so that an ecological balance can be re-established.

Another key function is the nutrient cycle, referring to transporting and transforming nutrients, such as nitrogen and phosphorus, within an ecosystem. These nutrients are a critical resource for primary producers, like algae and aquatic plants, whose growth underlies the food web.

Other types of impacts involve how human activities such as pollution, habitat destruction and climate affect the aquatic ecosystems. Eutrophication where excess nutrients in the water over-enrich water plants creates harm algal blooms and oxygen depletion that threatens aquatic life.

Freshwater ecological conservation seeks to conserve or restore ecosystems in ways that will ensure the ecosystems continue providing important services while supporting biodiversity. Thus, management practices are informed by fresh insights into freshwater ecological principles and complex environmental interactions.
