Frederic Clements
From Freepedia
Frederic Edward Clements (1874–1945) was an American plant ecologist and pioneer in the study of vegetation succession.
Born in Lincoln, Nebraska, he studied botany at the University of Nebraska, graduating in 1894 and obtaining a doctorate in 1898. (One of his teachers was botanist Charles Bessey, and he was a classmate of Willa Cather and Roscoe Pound.) While at the University of Nebraska, he met his future wife, Edith Gertrude Schwartz (1874–1971), also a botanist and ecologist.
In 1907 he was appointed professor for plant physiology at the University of Nebraska. From 1907 he was Professor of botany at the University of Minnesota in Minneapolis. From 1917 to 1941 he was employed as an ecologist at the Carnegie Institution of Washington in Washington, D.C., where he was able to carry out dedicated ecological research.
During winter he worked at research stations in Tucson, Arizona and Santa Barbara, California, while in the summer he performed fieldwork at the Carnegie's "Alpine Laboratory," a research station in Angel Canyon on the slopes of Pikes Peak, Colorado. During this time he worked alongside staff of the U.S. Soil Conservation Service. In addition to his field investigations, he carried out experimental work in the laboratory and greenhouse, both at the Pikes Peak station and at Santa Barbara.
From his work on the vegetation of Nebraska, Clements recognized that the vegetation cover does not represent a permanent condition but gradually changes over time, until it reaches an eventual "climax state."
In addition to botany, his research interests covered the systematics of fungi.
Among his works are:
- Research Methods in Ecology (1905)
- Plant Succession and Indicators (1928, reprinted 1973)
- Flower Families and Ancestors (1928, with Edith Clements)
- Plant Ecology (1929, with J.E. Weaver)
- The Genera of Fungi (1931, repr. 1965, with C. L. Shear)
In 1903, the flower Clementsia rhodantha ("Clements' rose flower"), a stonecrop, was named in honor of Frederic and Edith Clements. Clements died in Santa Barbara in 1945.
