Limnology a brief review with special reference to benthic zone
Keywords:
Limnology, lakes and ponds, benthic zones, benthic macro-invertebrate.Abstract
Limnology is the Greek word, limens means lake and logos means knowledge also called freshwater science, is the study of inland water. It is often recorded as a division of ecology or environmental science. It covers the biological, chemical, physical, geological and other attributes of all inland waters (running and standing waters, fresh and saline, natural or man-made). This includes the study of lakes and ponds, rivers, springs, streams and wetlands. A more recent sub discipline of limnology, termed landscape limnology, studies, manages and conserves these aquatic ecosystems using a landscape perspective. Benthos are the organisms that live on or inside the deposits at the bottom of water body (Idowo and Ugwumba, 2005). These organisms play a vital role in the circulation and recirculation of nutrients in aquatic ecosystem. Most benthic organisms feed on the debris and settle on the bottom of the water and in turn form a major food link in the food chain as fishes, birds and mammals depends directly orindirectly on this benthos as their food.
