The relationship between population characteristics and population productivity is fundamental to sustainable fisheries management, but predicting productivity remains a challenging task. Proposed mechanisms driving the variability in productivity at a given population size have included environmental and demographic factors related to the age structure of the population, but the broad-scale...
Dynamic seascapes, which are classified using a combination of remotely sensed data and model output, represent a potential tool for dynamic ecosystem-based management in marine systems. This work explores the utility of seascape classification in the context of marine resource management by examining two case studies: one involving biological relationships...
An impediment to use of exotic and bioengineered trees in many places is their propensity for spread by pollen and/or seeds. Our laboratory has been using gene editing to induce mutations in floral genes as means to impart stable and reliable genetic containment when this is desirable from social (markets,...
Uneven-aged management has been suggested as a method for balancing biodiversity conservation and wood production goals from managed forests in a variety of regions. In coastal Douglas-fir (Pseudotsuga menziesii) forests of the Pacific Northwest, implementation of uneven-aged management is hindered by a lack of experience with uneven-aged silvicultural systems, including...
Despite its promise as a potentially beneficial new source of energy, the ocean-based renewable energy industry is still in its infancy, and like any new idea there are many unknowns with the potential to affect both people and our natural environments. A permit for marine renewable energy (MRE) must cut...
Oregon is one of several states to implement a new and innovative minimum wage policy. The Oregon policy defines three regions with each having a separate initial minimum wage and a different set of incremental increases over the next seven years. This paper explores how this policy change may impact...
Osteoporosis is a common metabolic bone disease, affecting a third of women and a fifth of men over age 65. In the US, annual health care costs associated with osteoporosis are estimated to be over $20 billion. Osteoporosis is associated with increased fracture risk, which has been demonstrated to predict...
Researchers rely on bioeconomic models to guide research and generate fishery management advice for commercial fisheries. Due partly to a paradigm shift towards ecosystem based fishery management, increasing complexity in the characteristics of the problems has meant that bioeconomic simulation models are becoming more prevalent in the fisheries literature. However...
Stock assessments use statistical models and empirical data to re-create the population dynamics of a stock in order to provide estimates of biomass and fishing mortality rates to inform fisheries management. Fish stocks are not uniformly distributed across spatial regions, but stock assessments typically ignore stock spatial structure, for the...
Various ocean-climate models driven by increased greenhouse gases and higher temperatures predict a decline in oceanic dissolved oxygen (DO) as a result of greater stratification, reduced ventilation below the thermocline, and decreased solubility at higher temperatures. Since spreading of low oxygen waters is underway and predicted to increase, understanding impacts...
