Lee Raymond DiceDied 31 Jan 1977 at age 89 (born 15 Jul 1887).American zoologist, geneticist and ecologist who introduced biotic provinces to characterize areas of continuous ecological similarity in climate, soils, and topography. He investigated geographical and ecological distribution pertaining to plants and animals in fieldwork throughout the Southwest and Mexico in the 1920s and 30s. When he found C. Hart Merriam's idea of life zones to be inadequate for modeling distribution patterns, he developed his concept of biotic provinces. Dice demonstrated their application in his book, The Biotic Provinces of North America (1943). He is also known for his derivation of the Dice index, a similarity coefficient used to measure degree of association between biotic samples.«
