Aerial videography in combination with GPS were used to monitor the
active surge of Alaska's Bering Glacier. The large aerial extent of the study area and the
unpredictable weather in coastal Alaska required innovative techniques to be used in
order to successfully monitor the surge environment. A portable aerial videographic...
Geochemical characterization methods are commonly used in the reconstruction of prehistoric raw material use and procurement systems. Trace element studies of lithic source material and artifacts, specifically those made of obsidian, can reveal important information about the environmental and cultural factors which influence the prehistoric distribution of raw material. The...
Seasonally, in 1998 and 1999, I examined spatial and temporal variation in fish assemblages of agricultural, forested, and acid mine drainage tributaries within the Wayne National Forest (WNF) in southern Ohio. Land use and natural disturbance explained patterns in stream fish assemblages. Creek chub and green sunfish were present in...
The objective of this research project was to evaluate the toxicity of
local pyrrolizidine alkaloid containing plants and to examine the influence
of dietary protein, with particular reference to the amino acid cysteine,
upon this toxicity.
Senecio vulgaris (common groundsel) was shown to be more toxic than
Senecio jacobaea (tansy...
