Limnology is the take a look at of inland waters - lakes (each freshwater and saline), reservoirs, rivers, streams, wetlands, and groundwater - as ecological structures interacting with their drainage basins and the ecosystem. The limnological subject integrates the functional relationships of increase, edition, nutrient cycles, and biological productivity with species composition, and describes and evaluates how bodily, chemical, and organic environments alter those relationships.The phrase limnology is derived from the Greek limne - marsh, pond and Latin limnaea - issue referring to a marsh. stated clearly, limnology is the look at of the structural and practical interrelationships of organisms of inland waters as their dynamic bodily, chemical, and biotic environments affect them.Freshwater ecology is the observe of the shape, characteristic, and alternate of organisms in sparkling waters as affected by their dynamic physical, chemical, and biotic environments. Saline waters (> 0.three% or three g in line with liter) are excluded from this definition.Freshwater biology is the look at of the biological traits and interactions of organisms of sparkling waters. This study is largely constrained to the organisms themselves, inclusive of their biology, life histories, populations, or communities.
