Stretching over 750 km (450 mi) east to west from the Atlantic Ocean to the Appalachian mountains, the Commonwealth of Virginia spans five of the more than 20 major physiographic provinces found in North America (Fenneman 1938), making it one of the most diverse landscapes both topographically and floristically in the East. Because of its location between the glaciated, mountainous regions of t...

This study documents the effects of changing lake level (limnostasy), tectonics, sediment yield, and basin physiography on the facies architecture, sequence stratigraphy, and reservoir quality of three fine-grained deltas deposited along the eastern margin of late Pleistocene Lake Bonneville. Analysis of facies architecture indicates that the Weber and Spanish Fork deltas were strongly wavemodi...

Associations among nematode communities were studied in 18 Indiana mixed-hardwood stands of varying composition, soils, physiography, and past management practices. All sites were sampled in April, July, and October of 1968 and 1969. A total of 175 species representing eight orders were found, with 18 species occurring in all 18 sites, and approximately half the total species occurring in more ...
