The ecological interaction between the largest coastal predator, the gray whale (Eschrichtius robustus) and the most abundant shallow water marcrozooplanktonic prey, mysids, were examined in a poorly-understood predator-prey relationship along the central Oregon coast. From 2002-2008, 83 seasonal gray whales were identified. These whales returned each year around Memorial Day...
This study was designed to investigate the relationship between retinol intake, bone mineral density, and falls in 101 elderly women aged 72 to 90 years (78.6 yrs. ± 4.3 yrs.). Bone mineral density (BMD) (g/cm²) of the left hip, anterior-posterior lumbar spine (L3), and lateral spine (L3) was measured using...
The purpose of this study was to assess the usage of distance education in undergraduate dietetics programs. Additionally, the possibility of obtaining an undergraduate degree in dietetics via distance education was examined. The population receiving the survey research was all directors (279) of Commission on Accreditation for Dietetics Education (CADE)...
There is growing commercial interest in the use of unmanned aerial vehicles (UAVs) in urban environments, specifically for package delivery applications. However, the size, complexity and sheer numbers of expected UAVs makes conventional air traffic management that relies on human air traffic controllers infeasible. To enable UAVs to safely and...
Modeling and analyzing the combined effects of disease and population dynamics
is important in understanding the effects of mechanisms such as pathogen transmission
and direct competition between host species on the distribution and abundance of different
species in an ecological community. Mathematical analysis of such models in a
spatially explicit...
If it be true that the meaning of desserts is to
offer something more exquisite still, then from the
hygienic standpoint, the wisdom of the procedure is
nil unless it follows as a finishing grace to a simple
dinner of meat and vegetables. There is in this department
of culinary...
Otoferlin is a C2-domain, transmembrane protein whose mutated form is responsible for the DFNB9 subtype of prelingual hearing impairment. Mutations in otoferlin cause an autosomal recessive, non-syndromic form of deafness that is characterized by auditory neuropathy/ auditory dissynchrony (AN/AD), meaning that the outer hair cells (OHCs) are normal, and the...
Surface disinfection of fertilized fish eggs is widely used in aquaculture to reduce
extraovum pathogens that may be released from brood fish during spawning, and this is routinely
used in zebrafish (Danio rerio) research laboratories. Most laboratories use approximately 25-50 ppm unbuffered chlorine solution for 5-10 min. Treatment of embryos...
Most wild animals face concurrent challenges by multiple
infectious organisms, and immunological responses triggered by
some parasites may increase susceptibility to other infectious agents.
Immune-mediated interactions among parasites have been investigated
among individuals in a population, but less is known about
broader comparative patterns. We investigated the “macro-micro facilitation
hypothesis”...
Coastal Pacific hake (Merluccius productus) are known
to spawn in the southern California Bight from January
to March, migrate north during late spring and summer
to feed off Oregon, Washington, and British Columbia,
and then move back to southern California in the fall.
Juvenile Pacific hake nursery areas have been...
