Knowra Freshwater ecology Freshwater ecology Freshwater ecology studies organisms and ecological processes in inland waters, including lakes, rivers, streams, and wetlands. It examines how water conditions, habitats, and species interactions shape these ecosystems.
Thermal stratification : The formation of distinct temperature layers in a body of water, limiting vertical mixing. Layering controls oxygen and nutrient movement in lakes.
Lentic ecosystem : An inland-water ecosystem with still or standing water, such as a lake or pond. Standing-water systems have ecological patterns distinct from flowing waters.
Freshwater conservation : The protection and sustainable management of freshwater species, habitats, and ecosystems. Ecological knowledge identifies vulnerable habitats and conservation priorities.
Freshwater biodiversity : The diversity of genes, species, and ecosystems found in freshwater environments. Ecological processes sustain the unusually rich life concentrated in inland waters.
Climate change impacts on freshwater ecosystems : Changes in freshwater ecosystems caused by shifting temperatures, precipitation, ice cover, and extreme events. Climate change alters water conditions and species interactions across inland waters.
Eutrophication : The enrichment of water with nutrients, often causing excessive algal growth and oxygen depletion. Nutrient inputs can reorganize freshwater food webs and cause oxygen loss.
Lotic ecosystem : An inland-water ecosystem with continuously flowing water, such as a river or stream. Current and downstream transport shape these ecosystems.
River restoration : The repair of degraded rivers through actions that recover natural processes and habitat. Restoration uses ecological principles to rebuild river function and biodiversity.
Biogeochemical cycle : The movement of chemical elements between organisms and the atmosphere, water, and Earth's materials. Freshwaters transform and transport carbon, nitrogen, and other elements across landscapes.
Freshwater tipping point : A threshold beyond which a freshwater ecosystem can shift abruptly into a different state. Researchers investigate when gradual pressures trigger persistent ecological change.
