The purpose of this study was to determine what effect, if any, subtitles would have on listeners’
perceptions of expressivity in an operatic performance. Specifically, this study addressed the
following research questions: (1) Will there be differences in perceived expressivity among three
listening conditions (audio only, audio + video, audio...
The composition of global agricultural trade is shifting from primary commodities to processed foods in terms of value and quantity. It is important to understand the linkages between agriculture and food processing to identify the sources of the structural change in agricultural trade. The question addressed by this research is...
Several reports related to dams and dam removal have been released this decade by non-governmental organizations including Dam Removal: Science and Decision Making by The Heinz Center which focused on small dams, since most of the dams removed to date as well as those likely to be removed in the...
Host-selective toxins (HSTs) secreted by the pathogenic isolate of Pyrenophora tritici-repentis, BFP, are major pathogenicity factors in tan spot disease of wheat. Along with characterized HSTs such as Ptr ToxA (ToxA), BFP secretes at least two more uncharacterized toxic components. In an attempt to identify these additional components, 12 candidate...
1. The evaluation of the age and growth of animal populations is essential for understanding and
predicting how populations will respond to changes in environmental conditions and anthropogenic
stressors.
2. We used a novel, von Bertalanffy hierarchical modelling approach to quantify relationships between
the growth of three freshwater mussel species...
In the Klamath province of southwestern Oregon, Northern Spotted Owls (Strix occidentalis caurina) occur in complex, productive forests that historically supported frequent fires of variable severity. However, little is known about the relationships between Spotted Owl survival and home-range size and the characteristics of fire-prone, mixed-conifer forests of the Klamath...
Praying mantids look like something out of a horror movie, and they
truly are something to be feared by insects at least. They are harmless to people, though, and often are raised as pets. Gardeners love them due to their appetite for harmful insects. Most types (species) of mantids can...
Ladybug, ladybird, and lady beetle are a few of the common names for
this insect. Lady beetles are very common. In fact, there are more than
400 species in North America alone. The species most commonly seen in Oregon is the convergent lady beetle.
Processes that influence habitat selection in landscapes involve the interaction of habitat composition and configuration
and are particularly important for species with complex life cycles. We assessed the relative influence of landscape spatial
processes and local habitat characteristics on patterns in the distribution and abundance of spawning steelhead
(Oncorhynchus mykiss),...
