Measurements on growth traits up to 41 years of age
from 68 progeny sites in eight first-generation breeding
zones of coastal Douglas-fir (Pseudotsuga menziesii
[MIRB.] FRANCO var. menziesii) in the US Pacific Northwest
were used to investigate age trends of genetic parameters
and to determine optimum age of selection. Heritabilities...
Over the past decade, regional ocean observing systems have been established along nearly the entirety of the U.S. coastlines, forming a major component of the national Integrated Ocean Observing System (100S). Observations from these systems provide information to support decision making by governmental agencies and commercial enterprises, such as shipping...
The Bering Sea and Gulf of Alaska support a number of commercially important flatfish fisheries. These high latitude ecosystems are predicted to be most immediately impacted by ongoing ocean acidification, but the range of responses by commercial fishery species has yet to be fully explored. In this study, we examined...
Clostridium difficile is an important nosocomial pathogen that has become a major cause of antibiotic-associated diarrhea.
There is a general consensus that C. difficile spores play an important role in C. difficile pathogenesis, contributing to infection,
persistence, and transmission. Evidence has demonstrated that C. difficile spores have an outermost layer,...
This paper reports on a study of primary contextualization processes during science immersion
trips and the resultant student learning. Four High School Ecology classes (n=67) and teachers
participated. Through a pre/post assessment of science concept knowledge (Pathfinder Network
Modeling) and follow-up interviews with students, it was determined that (1) significant...
Many obligate symbiotic fungi are difficult to maintain in culture, and there is a growing need for alternative approaches to obtaining tissue and subsequent genomic assemblies from such species. In this study, the genome of Elaphomyces granulatus was sequenced from sporocarp tissue. The genome assembly remains on many contigs, but...
This manuscript presents a novel algorithm to automatically detect landslide movement in a forested area
using displacements of tree trunks distributed across the landslide surveyed repeatedly using terrestrial laser
scanning (TLS). Common landslide monitoring techniques include: inclinometers, global position system (GPS),
and interferometric synthetic aperture radar (InSAR). While these techniques...
Coastal foredunes protect lives, infrastructure, and ecosystems during severe storms. A range of approaches, ranging from simple (e.g., geometric) to complex (e.g., process-based) predictive models, have been developed to quantify overtopping and foredune retreat during storms. At present, however, there is no widely accepted approach for assessing the vulnerability of...
OBJECTIVE: To identify and rank perceived personal benefits from parenting practices that promote intake of calcium-rich foods and beverages (CRF/B) by early adolescents. METHODS: A convenience sample of parents/caregivers (n = 133) of early adolescents (10-13 years) from 6 states (CA, HI, MN, OH, OR, UT) participated in a qualitative...
