The Amphibian Research and Monitoring Initiative in the Pacific Northwest
M. J. Adams
2003, Fact Sheet 020-03
Amphibians have been disappearing from many locations around the world with reports of declines increasing in recent decades. Some of the most dramatic declines have occurred in areas that were thought to be protected from human disturbance. For example, the once-common boreal toad has virtually disappeared from Rocky Mountain National...
Effects of hydrology on red mangrove recruits
Thomas W. Doyle
2003, Fact Sheet 029-03
Coastal wetlands along the Gulf of Mexico have been experiencing significant shifts in hydrology and salinity levels over the past century as a result of changes in sea level and freshwater drainage patterns. Local land management in coastal zones has also impacted the hydrologic regimes of salt marshes and mangrove...
Probability of detecting atrazine/desethyl-atrazine and elevated concentrations of nitrate in ground water in Colorado
Michael G. Rupert
2003, Water-Resources Investigations Report 2002-4269
Draft Federal regulations may require that each State develop a State Pesticide Management Plan for the herbicides atrazine, alachlor, metolachlor, and simazine. Maps were developed that the State of Colorado could use to predict the probability of detecting atrazine and desethyl-atrazine (a breakdown product of atrazine) in ground water in...
Flow origin, drainage area, and hydrologic characteristics for headwater streams in the mountaintop coal-mining region of Southern West Virginia, 2000-01
Katherine S. Paybins
2003, Water-Resources Investigations Report 2002-4300
Characteristics of perennial and intermittent headwater streams were documented in the mountaintop removal coal-mining region of southern West Virginia in 2000?01. The perennial-flow origin points were identified in autumn during low base-flow conditions. The intermittent-flow origin points were identified in late winter and early spring during high base-flow conditions....
