How does rain influence the distribution and abundance of aquatic organisms such as fish, amphibians, and invertebrates by affecting habitat conditions, food availability, and reproductive success?

Rainfall influences the distribution and abundance of aquatic organisms by altering habitat conditions, food availability, and reproductive success in freshwater ecosystems such as rivers, lakes, and wetlands. Changes in water levels, flow regimes, and water quality associated with rainfall events can affect the behavior, physiology, and life history traits of fish, amphibians, and invertebrates, shaping their ecological interactions and population dynamics over time.
