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,
Forensic limnology Forensic limnology Forensic limnology is a sub-field of forensic botany, which examines the presence of diatoms in crime scene samples and victims. Different methods are used to collect this data but all identify the ratios of different diatom colonies present in samples and match those samples with locations at the crime scene. Diatoms are diverse microscopic algae with silica cell walls that have different characteristics such as color, shape, and size. There are 8,000 known species of diatoms (without taking into account the variety of subspecies that have specialized within their specific environments). Diatoms do not have specialized nutrient and
