Perspectives on the land use history of North America: A context for understanding our changing environment Perspectives on the land use history of North America: A context for understanding our changing environment
Ecological change is constant and profound, yet it often occurs at temporal and spatial scales that are difficult to measure and interpret. This publication demonstrates how diverse data bases, archived in different formats and at numerous locations, can be brought together to provide an integrated perspective on the relationship between land use and landcover change. The authors provide...

Riparian-vegetation controls on the spatial pattern of stream-channel instability, Little Piney Creek, Missouri Riparian-vegetation controls on the spatial pattern of stream-channel instability, Little Piney Creek, Missouri
The role of riparian vegetation is assessed quantitatively by using a five-decade record of valley bottom vegetation and channel dynamics developed from historical aerial photography. A 12-kilometer reach of a typical Ozarks stream was mapped using aerial photographs from 1938, 1948, 1955, 1965, 1976, and 1989; maps were then analyzed in a digital geographic information system. Analysis...

Source and transport of desethylatrazine and desisopropylatrazine to groundwater of the midwestern United States Source and transport of desethylatrazine and desisopropylatrazine to groundwater of the midwestern United States
Based on usage of the parent compounds and studies of their dissipation in corn fields, atrazine (6-chloro-N-ethyl-N'-(1-methylethyl-1,3,5-triazine-2,4-diamine)), cyanazine (2-[[4-chloro-6-(ethylamino)-1,3,5-triazin-2-yl]amino]-2-methylpropionitrile), and simazine (6-chloro-N,N'diethyl-1,3,5-triazine-2,4-diamine) are thought to be the important contributors of desethylatrazine (6-chloro...

Comparative sensitivity of five species of macrophytes and six species of algae to atrazine, metribuzin, alachlor, and metolachlor Comparative sensitivity of five species of macrophytes and six species of algae to atrazine, metribuzin, alachlor, and metolachlor
This study determined the relative sensitivity of five species of aquatic macrophytes and six species of algae to four commonly used herbicides (atrazine, metribuzin, alachlor, and metolachlor). Toxicity tests consisted of 96-h (duckweed and algae) or 14-d (submerged macrophytes) static exposures. The triazine herbicides (atrazine and metribuzin) were significantly more toxic to aquatic...

Common and scientific names of aquatic invertebrates from the United States and Canada: Mollusks Common and scientific names of aquatic invertebrates from the United States and Canada: Mollusks
This edition of Common and Scientific Names of Invertebrates from the United States and Canada: Mollusks represents the efforts of 15 molluscan taxonomic specialists in compiling a comprehensive checklist of the mollusks found in North America and Canada and their vernacular names. Built upon the success of the first edition, the authors have updated the nomenclature to reflect recent...

A table of polyatomic interferences in ICP-MS A table of polyatomic interferences in ICP-MS
Spectroscopic interferences are probably the largest class of interferences in ICP-MS and are caused by atomic or molecular ions that have the same mass-to-charge as analytes of interest. Current ICP-MS instrumental software corrects for all known atomic “isobaric” interferences, or those caused by overlapping isotopes of different elements, but does not correct for most polyatomic...
