Three studies were conducted related to the measurement and impact of
stream sediment fecal coliform (FC) bacteria on stream water quality. In part one
an enumeration technique for sediment FC was defined and statistically
characterized. This characterization necessitated the development of a sample
splitting mechanism, which was found to split...
As the demand for community mental health services grows, more and more counselors-in-training are being asked to face the challenge of working with high needs clients, including clients with Borderline Personality Disorder (BPD). Counselors-in-training are entering therapeutic relationships with high-risk clients without training specifically covering BPD client's unique needs. This...
The vast majority of terrestrial plant species live in symbiosis with arbuscular mycorrhizal fungi (AMF). AMF and plants live in complex networks, with roots of individual plants hosting multiple AMF, and single AMF colonizing multiple plants concurrently. Through the exchange of resources, the two partners of this symbiosis can have...
Vibrio tubiashii is reported to be a bacterial pathogen of larval Eastern oysters (Crassostrea virginica) and Pacific oysters (Crassostrea
gigas) and has been associated with major hatchery crashes, causing shortages in seed oysters for commercial shellfish
producers. Another bacterium, Vibrio coralliilyticus, a well-known coral pathogen, has recently been shown to...
We present a spatially extensive record of dinitrogen (N₂) fixation rates and distributions
of N₂ fixing microorganisms along with the results of exogenous phosphorus (P) addition experiments
conducted during a series of cruises in the North Pacific Subtropical Gyre (NPSG). We measured the
N₂ and carbon (C) fixation rates of...
OBJECTIVE: To evaluate the effectiveness of a 3-month treadmill desk intervention in eliciting changes in physical activity and sedentary behavior among overweight/obese office workers. METHODS: A randomized controlled trial was conducted among overweight/obese office workers (n=41; mean age = 40.1 ± 10.1 years) at a private workplace. Participants were randomly...
Evolutionary interactions across levels of biological organization contribute to a variety of fundamental processes including genome evolution, reproductive mode transitions, species diversification, and extinction. Evolutionary theory predicts that so-called “selfish” genetic elements will proliferate when the host effective population size (N[subscrit]e) is small, but direct tests of this prediction remain...

Evolutionary interactions across levels of biological organization contribute to a variety of fundamental processes including genome evolution, reproductive mode transitions, species diversification, and extinction. Evolutionary theory predicts that so-called “selfish” genetic elements will proliferate when the host effective population size (N[subscrit]e) is small, but direct tests of this prediction remain...
BACKGROUND: Low levels of moderate-to-vigorous physical activity are associated with adverse health consequences.
OBJECTIVE: The intent of the study was to determine the feasibility and efficacy of a 12-week physical activity promotion program
targeting children, which was delivered to parents through mobile phones.
METHODS: Potential participants were recruited through advertisements...
