Nutrient and triazine-herbicide concentrations in streams of the Chickies Creek Basin, south-central Pennsylvania, during low-flow conditions Nutrient and triazine-herbicide concentrations in streams of the Chickies Creek Basin, south-central Pennsylvania, during low-flow conditions
Excessive nutrients and herbicides in surface and ground water can affect human health and the aquatic life in Chickies Creek. Potential sources of these contaminants are all around us—direct application of nutrients and herbicides on land, discharge from wastewater-treatment and septic systems, and even deposition from the atmosphere. However, by far the largest source in the Chickies...

A new era for carnivore conservation A new era for carnivore conservation
Restoration has become an important technique in carnivore management. As the public becomes increasingly interested in carnivores, their management may become more contentious. Nevertheless, the value of this charismatic group of animals is high. Although they will have to be controlled where interfering too much with human activities, they should also be nurtured wherever they can live

Evaluation of 3 radio transmitters and collar designs for Amazona Evaluation of 3 radio transmitters and collar designs for Amazona
I evaluated 3 radio transmitter attachments and designs for adult parrots. Two of the transmitters and attachments were similar to those used previously in the study on fledgling and adult parrots. I designed, in collaboration with the manufacturer, a third transmitter and attachment that provided protection of key areas from chewing and eventual destruction of the attachment or...

Fluorspar Fluorspar
The U.S. consumed about 525 kt of fluorspar in 1995, with more than 70 percent being used for the production of hydrofluoric acid. Fluorspar is also used for the production of aluminum and steel. About 558 kt of fluorspar was imported in 1995, with a further 186 kt made available from the National Defense Stockpile. The market in the U.S. is expected to grow as increasing use is made of

Development of cytochromes P450 in avian species as a biomarker for environmental contaminant exposure and effect: Procedures and baseline values Development of cytochromes P450 in avian species as a biomarker for environmental contaminant exposure and effect: Procedures and baseline values
As in mammals and fish, birds respond to many environmental contaminants with induction of hepatic cytochromes P450. In order to monitor cytchromes P450 in specific avian species, for assessing the status of that species or the habitat it utilizes, it is necessary to have background information on the appropriate assay conditions and the responsiveness of cytochrome P450 induction in...
