Biography

Donald Johnson is, and has been, involved in various collaborative process and theoretical studies in soil geomorphology, tectonic geomorphology, pedology, geoarchaeology, and Quaternary zoogeography. Research areas include, or have included, various areas in the United States, Caribbean (Jamaica, Bonaire, Curacao), Central and South America (Costa Rica, Nicaragua, Ecuador-Galapagos, Venezuela, Argentina, Brazil), Australia (N.S.W., Northern Territories, Queensland, South Australia, Victoria, A.C.T.), and Africa (Egypt Sudan, Ethiopia, Kenya, Tanzania, Ivory Coast, Burkina Faso, Mozambique, South Africa). Long-term research is on soil geomorphologic theory, particularly applications of dynamic denudation-biomantle theory, and on soil geomorphologic problems, involving select areas of California, including offshore Channel Islands, and of Arizona, Arkansas, Illinois, Idaho, Iowa, Louisiana, Minnesota, Missouri, Mississippi, Oklahoma, Oregon, Texas, Utah, and Washington. A principal research focus is on the role of biota in soil and landform evolution. Other key interests are: biodynamic evolution of tropical-subtropical-middle-high latitude landscapes: soils that contain stonelayers (stone-lines), and what stone-lines mean genetically; philosophy of science; and Mima mounds as locally thickened, point-centered biomantles -- and how their formation (on level or low slope ground) automatically promotes the co-formation of associated vernal pools. Drawing on these endeavors, Johnson and co-workers have formulated new concepts, principals, general truths, models, and paradigms in pedology, geomorphology, and geoarchaeology. Chief among these is the dynamic denudation framework, anchored by biomantle theory. Such theoretical perspectives provide new and different—and realistic—insights to understanding the evolution of earth landscape and its epidermal soil.
