The main theme of this research is the application of geographic techniques in a study involving environmental monitoring and analysis of the associations between landscape and in-stream characteristics in the Pacific Northwest. The geographic techniques used in this study include (1) geographic information systems (GIS) coupled with statistical analysis and...
The rationale for this study lies in the upsurge of home food
preservation which has occurred as a result of the unprecedented rise
in food prices and, concommitantly, the danger and economic loss
entailed in the use of faulty methods. A sample of 200 non-urban
homemakers in the province of...
Past disasters such as mercury poisoning in Minimata, and new problems such as tributyltin impacts on shellfish have maintained public concern about problems caused by chronic discharges of hazardous materials into marine waters (Clark, 1986; U.S. Congress, 1987). However, hazardous chemical spills in coastal waters typically escape public attention. Unlike...
Dramatic and ongoing changes pervading the Arctic and subarctic seas over
recent decades have motivated this effort to track and better understand hydrographic
variability using chemical tracers. Particular emphasis has been paid to differentiating
freshwater contributions to upper layers: namely Pacific water, meteoric water, and
sea-ice melt/formation.
Data collected in...
The present work shows predatory behavior of the social orb-weaver spider, Geratonephila burmanica n. gen., n. sp. (Araneae: Nephilidae) against a parasitic wasp, Cascoscelio incassa n. gen., n. sp., (Hymenoptera: Platygasteridae) in Early Cretaceous Burmese amber. An adult male and juvenile of Geratonephila burmanica n. gen., n. sp. in the...
