WEBJan 1, 1991 · An interesting principle demonstrated in Cedar Bog Lake (Lindeman, 1941b) is that during late lake senescence general productivity (2,) is increasingly influenced by climatic factors, acting through water level changes, drainage, duration of winter ice, snow cover, etc., to affect the presence and abundance of practically all food groups in the ...
WEBExperimental studies of energy flow in lake ecosystems close to Cedar Creek Bog have verified the power and longevity of Lindeman’s approach and further quantified the important role of terrestrial energy subsidies to aquatic biota (Pace et al. 2004 and references within). Experimental manipulations of allochthonous energy flow in low-order,
Raymond Lindeman (1915-1942) | College of Biological Sciences
WEBRaymond Lindeman began collecting data for his doctoral thesis at Cedar Creek in 1936 and received his Ph.D. in zoology from the University of Minnesota in March of 1941. His thesis provided revolutionary new insights into how energy and nutrients move through ecosystems, beginning with photosynthesis and traveling up the food chain.
WEBRaymond Lindeman is best known for developing and advocating a conceptual approach, but he knew his organisms, and as we’ll remember here, he built his theory on a solid foundation of his knowledge of natural history and paleoecology.

WEBStudy area: Trophic efficiencies at the various trophic levels in two lakes; lake Mendota, Minnesota and Cedar Bog lake. According to Lindeman’s Law of 10%, the efficiency of energy transfer from one trophic level to the next is about 10%.
WEBLindeman's empirically based generalizations that both progressive efficiencies and percent of energy lost due to respiration increase with trophic level appeared contradictory, because he linked trophic levels in series to form a simple trophic chain.
WEBLindeman arrives at several very general relations regarding the flow of energy in ecosystems. In the final section of the paper these relations are brought to the analysis of successional devel- opment, with particular emphasis on rate-controlling processes and the eco- logical efficiency of energy transfer over this expanded time scale.
