Spatially explicit ecosystem service valuation (ESV) allows for the identification of the location and magnitude of services provided by natural ecosystems to human activities along with a measure of their significance based upon economic valuation. While ESV has been used to provide new insight into land use management, few studies...
A well-defined, quantitative model for determining soil contrast
was developed to improve soil survey interpretations concerning the
effects of mixtures of different kinds of soils on agricultural land
use. The model was evaluated by determining the levels and reasons
for soil contrast on mapped soil areas representing 5 different
landscapes,...
Numerous flights of Quaternary marine terraces are present around the island of Cyprus, in the Eastern Mediterranean. These terraces are a result of the global eustatic sea-level curve and local tectonism. Marine Isotope Stage (MIS) 5 through MIS 13 terraces are identified, mapped and dated. Palaeoshoreline elevation, an excellent indicator...
Understanding which factors motivate farmers to adopt certain practices is an important part of helping to solve many agri-environmental issues. This study uses 19 interviews with farmers along Oregon’s Willamette River, a statewide producer survey, and select interviews with organizations and agencies active in the farming community to examine the...
As engineered nanomaterials (ENM) become more common in consumer products, it is crucial to rapidly assess toxicity of unique ENM. Previous studies rarely focused on standardizing nanotoxicity testing, leading to inconsistent and irreproducible results. This study characterized a variety of ENM of different size, shape, core type, and surface charge...
Detection of L-serine and D,L-alanine by juvenile coho salmon (Oncorhynchus kisutch) was measured in a two-choice Y-trough. Threshold concentration for olfactory
detection of L-serine was 10-8 M for zero-age parr, 1O-7 M for yearling parr, 10-5 M for smolts in late April-early May, and 10-6 M for smolts in June....
Corn oil (CO) and Sterculic foetida oil (SFO) fed rats were
injected with [9, 10-methylene-¹⁴C]sterculic acid. Less than 1%
of the label was expired as carbon dioxide. The majority of the
label was excreted in the urine as short-chain dicarboxylic acids with
an intact cyclopropane ring. The major metabolites for...
