Recent climate change forecasts have aroused growing interest in the influence of water
scarcity and climate on agricultural production and irrigation practice. However, it is common in
the economic literature to aggregate disparate crops when modeling irrigation choices. That
approach confounds the crop-specific effects of climate and water scarcity that...
An automated on-line ion exchange trace enrichment system has
been developed to improve the detection limits of flame atomic
absorption (AA) spectrophotometry in the determination of trace
metals in natural waters. The sample solution is passed through a
column of Chelex-100 chelating resin by a carrier buffer stream
delivered from...
Timber-dependent, rural communities in the Pacific Northwest face dramatic economic, political, and cultural change. New philosophies of forest management, primarily formulated in urban communities, require new approaches to the use and extraction of resources. What are the roles of rural communities that wish to adapt and sustain themselves? Two rural...
At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...
Frost injury is one of the major factors limiting potato production in many parts
of the world. It would be desirable to transfer the frost-tolerance traits from the hardy
relatives to the cultivated potato, however, progress has been very slow. Since Solanum
commersonii has been the major source of frost...

A study of the relative rates of the alkyl hydrogen abstraction
from a series of meta and para substituted t-butylbenzenes by the
chlorine atom at 70°C has been carried out. Application of the
Hammett equation yielded a ρ value of -0.44 for the para compounds.
Possible explanations for the non-linearity...
