1. Globally, river systems have been extensively modified through alterations in riverscapes and flow regimes, reducing their capacity to absorb geophysical and environmental changes.
2. In western North America and elsewhere, alterations in natural flow regimes and swimways through dams, levees, and floodplain development, work in concert with fire regime,...
The aims of this study were first, to test the hypothesis that metrics of fish growth and condition relate positively to parasite species richness (S[subscript R]) in a salmonid host; second, to identify whether S[subscript R] differs as a function of host origin; third, to identify whether acquisition of parasites...
Better fisheries management is often given as one justification for research on improving forecasts of fish survival. However, the value gained from expected improvements in forecast skill in terms of achieving management goals is rarely quantified as part of research objectives. Using Monte Carlo simulations of population dynamics, we assessed...
Multiple analytical techniques were used to evaluate the impact of multiple parasite species on
the mortality of threatened juvenile coho salmon (Oncorhynchus kisutch) from the West Fork Smith
River, Oregon, USA. We also proposed a novel parsimonious mathematical representation of
macroparasite distribution, congestion rate, which i) is easier to use...
