This document discusses the influence of density, fertilization, and the environment on the growth, survival, and yield of salmonid fry reared in freshwater impoundments.
Predation by piscivorous marine fishes has been hypothesized to be a primary source of marine
mortality for Pacific Northwest juvenile salmon. During the springs and summers of 1998–2004, we collected predator and prey fishes (forage and juvenile salmonids) at the surface at night off the mouth of the Columbia River....
Developmental bisphenol A (BPA) exposure is associated with adverse behavioral
effects, although underlying modes of action remain unclear. Because BPA is a
suspected xenoestrogen, the objective was to identify sex-based changes in adult
zebrafish social behavior developmentally exposed to BPA (0.0, 0.1 or 1 μM) or one of
two control...
When we think of voices in the library, we have tended to think of them as disruptive, something to control and manage for the sake of the total library environment. The stereotype of the shushing librarian pervades public perception, creating expectations about the kinds of spaces libraries want to create....
Lidar is currently the most accurate method for remote estimation of forest structure, but it has limited spatial and temporal coverage. Conversely, Landsat data are more widely available, but exhibit a weaker relationship with structure under medium to high leaf area conditions. One potentially valuable means of enhancing the relationship...
Designing A Citizen Involvement Program presents a model and supportive materials that can be used to design and implement a program for involving citizens in decision-making that concerns significant environmental issues. These actions might be large-scale construction projects, such as building a dam, an electric power plant, or a nuclear...
North Atlantic right whales (Eubalaena glacialis) were found in an important nineteenth century whaling area east of southern Greenland, from which they were once thought to have been extirpated. In 2007–2008, a 1-year passive acoustic survey was conducted at five sites in and near the ‘Cape Farewell Ground’, the former...
Genetic linkage maps have the potential to facilitate the genetic dissection of complex traits and comparative analyses of genome structure, as well as molecular breeding efforts in species of agronomic importance. Until recently, the majority of such maps was based on relatively low-throughput marker technologies, which limited marker density across...
