Douglas-fir and western hemlock growth and stocking were examined on two neighboring clear-cut watersheds in the Western Cascades of Oregon and related to the intensity of burning and logging disturbance, habitat type, soil type, aspect and the influence of percent cover of both invading Ceanothus species and residual Acer circinatum....
Coral reef ecosystems are the most diverse on earth, and their subsistence is being threatened by natural and adverse anthropogenic patterns and processes. In an effort to understand and protect these marine environments, several programs have outlined strategies and initiatives. For example, the United States Coral Reef Task Force’s Mapping...
Coral reefs around the world face numerous threats, both natural and
anthropogenic, including pollution, natural disasters, invasive species, habitat destruction,
and destructive methods of fishing. Given enough time, coral can recover from natural
disasters, but anthropogenic threats decrease corals’ ability to recover from things such as
hurricanes. It is difficult...
In the era of #MeToo, we have learned more about the plight of women in Hollywood as they seek employment as actors. While the recent public conversation about gender and sexualization in Hollywood is robust, few peer-reviewed academic articles examine the actor’s personal experiences of gaining meaningful employment in television...
During the past two decades, interest has grown in the role and welfare implications of different head and neck positions (HNPs) in equine biomechanics as well as dressage training and competition. To evaluate the influence of HNP on stride length, 17 horses of varying breeds and dressage levels were studied...
Equine-facilitated mental health (EFMH) is a practice within equine-assisted therapy
(EAT) that has expanded greatly in the last 20 years, but scientific research is still
lacking. Thus far, no attempt has been made to characterize the horses and ponies
currently used in EFMH programs, or to define what characteristics EFMH...
The development of new technologies in science is a balance between existence and use. There are three versions of this duality – something is built and users come, something is built and users don’t come, and, finally, potential users show up but the ballpark has not yet been built. In...
Mixed linear models are a time honored method of analyzing correlated data. However, there is still no method of calculating exact confidence intervals or p-values for an arbitrary parameter in any mixed linear model. Instead, researchers must use either specialized approximate and exact tests that have been developed for particular...
Streptococcus gordonii (S. gordonii) is being developed as a Gram-positive
expression vector for the expression of heterologous proteins. This bacterial
expression system takes advantage of the natural pathway of protein export and
anchoring on the surface of the bacterium. The expression of heterologous proteins
relies on the homologous recombination of...
I conducted acoustic lure surveys of northern pygmy-owls (Glaucidium gnoma) on transects that were systematically placed in forested areas throughout the state of Oregon. My objectives were to determine if pygmy-owls were associated with particular forest types, ecoregions, or with large-diameter dominant overstory trees. I also examined temporal variation in...
