A case history of a dynamic resource--the red fox A case history of a dynamic resource--the red fox
Red fox (Vulpes vulpes) population trends in midwestern North America since 1800 were examined. During 1801-1900, the red fox expanded its range south to include most of the region, but populations remained low in most areas. During 1901-30, it became scarce or absent in many northern areas but was common in southern areas. During 1931-45, populations in most of the region increased to...

A topology of mineralization and its meaning for prospecting A topology of mineralization and its meaning for prospecting
Epigenetic mineral deposits are universal members of an orderly spatial and temporal arrangement of igneous rocks, endomorphic rocks, and hydrothermally altered rocks. The association and sequence of these rocks is invariant whereas the metric relations and configurations of the properties of these rocks are unlimited in variety. This characterization satisfies the doctrines of topology...

Atlantic continental margin of the United States Atlantic continental margin of the United States
The objective of this Decade of North American Geology (D-NAG) volume will be to focus on the Mesozoic and Cenozoic evolution of the U.S. Atlantic continental margin, including the onshore coastal plain, related onshore Triassic-Jurassic rift grabens, and the offshore basins and platforms. Following multiple compressional tectonic episodes between Africa and North America during the...
