|Chaney's University of California: In Memoriam obituary notes that his "most significant contribution to paleobotany was to consider fossil plants as members of forest associations and not as isolated morphologic entities. Thus he was the first to adopt an ecological approach to the description and analysis of Tertiary floras in western North America, and to apply it over a much larger geographic area adjacent to the Pacific basin. His quantitative studies of the relationships between the accumulations of recent leaves in stream pools and the surrounding vegetation provided a technique whereby objective inferences concerning past vegetation could be derived from the statistical analysis of leaves and other organs in fossil floras." Chaney's approach required the sifting of large amounts of data, and he traveled widely--both within Western America, and to Central and South America, Mongolia, Japan, Korea, and China. Among Chaney's innovations was his depiction of the "geoflora," a large scale dispersal of forms in time and space (for example, in response to permanent climatic shifts). One odd outcome of his work on paleofaunas and systematics was his interest in the Chinese redwood genus Metasequoia, and by extension Californian forms: late in life he became a leading advocate for their conservation.|
