At the Siuslaw Estuary or some adjacent areas, U. S. Fish and Wildlife Service (USFWS) Biologists John Annear, John Cornely, and Roy Lowe conducted 67 censuses; Maureen Woolington made 90 censuses, and Range Bayer completed 429 censuses. Unfortunately, these censuses do not give a complete picture of the seasonality, abundance,...
Increasingly diverse interests in commercial and recreational use of marine resources are creating new challenges for coastal ocean management. One concern of increased offshore use and development off the Oregon coast is the potential impact on marine bird populations. We summarized the primary surveys of seabird breeding colonies and at-sea...
One of the important ‘hallmarks’ of cancer is angiogenesis, which is the process of formation of new blood vessels that are necessary for tumor expansion, invasion and metastasis. Under normal physiological conditions, angiogenesis is well balanced and controlled by endogenous proangiogenic factors and antiangiogenic factors. However, factors produced by cancer...
For many historical and contemporary experimental studies in marine biology, seawater carbonate chemistry remains a ghost factor, an uncontrolled, unmeasured, and often dynamic variable affecting experimental organisms or the treatments to which investigators subject them. We highlight how environmental variability, such as seasonal upwelling and biological respiration, drive variation in...
Continuing education workshops and shortcourses are playing an increasingly important role in the education of forest resource professionals. The “tug-of-war” between breadth and depth in undergraduate curricula, combined with pressure to reduce the number of credit hours required for graduation, create knowledge gaps in various disciplines. Workshops and shortcourses help...

An emerging area in environmental toxicology is the role that chemicals and chemical mixtures have on the cells of the human immune system. This is an important area of research that has been most widely pursued in relation to autoimmune diseases and allergy/asthma as opposed to cancer causation. This is...
We investigated multiple-rate diffusion as a possible explanation for observed behavior in a suite of single-well injection-withdrawal (SWIW) tests conducted in a fractured dolomite. We first investigated the ability of a conventional double-porosity model and a multirate diffusion model to explain the data. This revealed that the multirate diffusion hypothesis/model...
