Razor clams from Clatsop Beach (Tillamook Head to Columbia River) were sampled regularly from March through September and periodically the rest of the year. Sport and commercial diggers were interviewed to obtain data on number, age composition of clams dug and harvest area. Data from other beaches south of Tillamook...
Marine teleost fishes often experience over 99% mortality in the early life stages (eggs and larvae), yet larval survival is essential to population sustainability. Marine fish larvae from a wide range of families display elaborate, delicate features that bear little resemblance to adult forms and hinder their swimming escape ability...
While libraries are using increasingly sophisticated metrics to determine electronic resources’ usefulness, impact and cost effectiveness, much of this data reflects past usage. More nuanced information is still needed to guide collection managers’ decisions about which content to purchase, borrow or deselect. To fill this gap, librarians at OSU Libraries...
DNA methylation is a well-recognized epigenetic mechanism that has been the subject of a growing
body of literature typically focused on the identification and study of profiles of DNA methylation and their
association with human diseases and exposures. In recent years, a number of unsupervised clustering algorithms,
both parametric and...
dependence and regulation of relatively large local populations? If so, what are the causative mechanisms and their implications? We conducted an eight-year multigeneration study of population dynamics of bicolor damselfish (Stegastes partitus) inhabiting four large coral reefs in the Bahamas. After a four-year baseline period, it was clear that two...
Background: Statins substantially reduce cardiovascular disease risk and are generally well-tolerated, but many patients discontinue therapy. A better understanding of the characteristics of current and former statin users may be helpful for formulating strategies to improve long-term adherence.
Objective: The Understanding Statin Use in America and Gaps in Education (USAGE)...
Inherited age is defined herein as the difference between times of carbon fixation in a material and deposition
of that material within sediments from which it is eventually sampled in order to estimate deposit age via
radiocarbon dating. Inheritance generally leads to over-estimation of the age by an unknown amount...
Most forest managers would agree that soils are a fundamental resource of forestlands, yet many planning and management decisions continue to be made without a detailed and spatially explicit understanding of this unique and vital resource. We discuss the value of soil data and interpretations in forest planning. We emphasize...
Groundwater–surface-water (GW-SW) interactions in streams are difficult to quantify because of heterogeneity in hydraulic and reactive processes across a range of spatial and temporal scales. The challenge of quantifying these interactions has led to the development of several techniques, from centimeter-scale probes to whole-system tracers, including chemical, thermal, and electrical...
The potential influence of underlying differences in relative leukocyte distributions in studies involving blood-based profiling of DNA methylation is well recognized and has prompted development of a set of statistical methods for inferring changes in the distribution of white blood cells using DNA methylation signatures. However, the extent to which...
