Additionally, efficacy of combined protocols was determined. Heat shock 10 min after fertilization induced triploidy when incubation temperature was 24 C but not when incubation...
Are shifts in herbicide use reflected in concentration changes in Midwestern rivers?
W.A. Battaglin, D. A. Goolsby
1999, Environmental Science & Technology (33) 2917-2925
In many Midwestern rivers, elevated concentrations of herbicides occur during runoff events for 1-3 months following application. The highest or 'peak' herbicide concentration often occurs during one of these runoff events. Herbicide concentrations in rivers are affected by a number of factors, including herbicide use patterns within the associated basin....

Hydrobiogeochemical interactions in 'anoxic' limestone drains for neutralization of acidic mine drainage
E. I. Robbins, C.A. Cravotta III, C.E. Savela, Gordon L. Nord Jr.
1999, Fuel (78) 259-270
Processes affecting neutralization of acidic coal mine drainage were evaluated within `anoxic' limestone drains (ALDs). Influents had pH≤3.5 and dissolved oxygen <2 mg/l. Even though effluents were near neutral (pH>6 and alkalinity>acidity), two of the four ALDs were failing due to clogging. Mineral-saturation indices indicated the potential for dissolution of calcite...
Parasites and commensals of the West Indian manatee from Puerto Rico

The maximum detected subsidence during...
Mass stranding of wedge-tailed shearwater chicks in Hawaii
Thierry M. Work, Robert Rameyer
1999, Journal of Wildlife Diseases (35) 487-495
Unusual numbers of wedge-tailed shearwater (Puffinus pacificus) chicks stranded on Oahu (Hawaii, USA) in 1994. Compared to healthy wedge-tailed shearwater (WTSW) chicks, stranded chicks were underweight, dehydrated, leukopenic, lymphopenic, eosinopenic, and heterophilic; some birds were toxemic and septic. Stranded chicks also were hypoglycemic and had elevated aspartate amino transferase levels....
A historical perspective and critique of the declining amphibian crisis
R. Bruce Bury
1999, Wildlife Society Bulletin (27) 1064-1068
Losses of amphibian species and populations are of global concern (Blaustein and Wake 1990, Wyman 1990, Wake 1991, Vial and Saylor 1993, Blaustein 1994) and have been the focus of an increasing number of studies. Still, neither all regions nor all species have declines (Dodd 1997; Green 197; Corn, in...

Geochemistry and hydromechanical interactions of fluids associated with the San Andreas fault system, California
Yousif K. Kharaka, James J. Thordsen, William C. Evans, B. Mack Kennedy
1999, Book chapter, Faults and subsurface fluid flow in the shallow crust
18O values establish that waters are predominantly of meteoric origin. The chemical compositions of water and gases are controlled mainly by the ambient rock types, and chemical geothermometry gives reservoir temperatures of 80-150 degrees C indicating shallow to moderate circulation depths of up to 6 km. However, compositions and isotope...
Mercury
J. C. Franson
1999, Information and Technology Report 1999-0001
Mercury has been used by humans for over 2,000 years and was associated with premature deaths of cinnabar (mercuric sulfide) miners as early as 700 B.C. More recent human poisonings have been related to agricultural and industrial uses of mercury. One of the best documented of these cases occurred in...
