Limnology zoologist) and Einar Naumann (a Swedish botanist) co-founded the International Society of Limnology (SIL, from Societas Internationalis Limnologiae). Forel's original definition of limnology, "the oceanography of lakes", was expanded to encompass the study of all inland waters, and influenced Benedykt Dybowski's work on Lake Baikal. Prominent early American limnologists included G. Evelyn Hutchinson, Ed Deevey, E. A. Birge, and C. Juday. Physical properties of aquatic ecosystems are determined by a combination of heat, currents, waves and other seasonal distributions of environmental conditions. The morphometry of a body of water depends on the type of feature (such as a lake, river,
Landscape limnology ecosystem research, management, and conservation. Landscape limnology is especially relevant for geographical areas with thousands of ecosystems (i.e. lake-rich regions of the world), in situations with a range of human disturbances, or when considering lakes, streams, and wetlands that are connected to other such ecosystems. For example, landscape limnology perspectives have contributed to the development of nutrient criteria for lakes, formation of classification systems that can be used to monitor the health of aquatic ecosystems, understanding ecosystem responses to environmental stressors, or explaining biogeographic patterns of community composition. Landscape limnology Landscape limnology is the spatially explicit study of lakes, streams,
