Freshwater biology focuses on the life forms that inhabit rivers, lakes, and other non-saline water bodies. This field studies species diversity, behaviors, and interactions within freshwater ecosystems. Freshwater biologists work to understand how organisms adapt to various environmental factors such as water flow, temperature, and nutrient availability. They also explore how changes in water quality and habitat fragmentation impact species like fish, amphibians, and invertebrates. Research in freshwater biology is fundamental for conservation efforts, as it informs strategies for preserving biodiversity, protecting endangered species, and maintaining healthy aquatic ecosystems that provide essential resources for human and ecological well-being.
