Abstract In mountainous river basins of the Pacific Northwest, climate models predict that winter warming will result in increased precipitation falling as rain and decreased snowpack. A detailed understanding spatial temporal dynamics water sources across networks help illuminate change impacts on flow regimes. Because stable isotopic composition varies geographically, variation surface isotope ratios indicates volume‐weighted integration upstream source water. We measured samples collected...
Abstract. Climate change is modifying river temperature regimes across the world. To apply management interventions in an effective and efficient fashion, it critical to both understand underlying processes causing stream warming identify streams most least sensitive environmental change. Empirical thermal sensitivity, defined as water with a single degree air temperature, useful tool characterize historical conditions predict how might respond future climate warming. We measured Snoqualmie...
Globally, ocean dumping of chemical waste is a common method disposal and relies on the assumption that dilution, diffusion, dispersion at scales will mitigate human exposure ecosystem impacts. In southern California, extensive agrochemical waste, particularly chlorinated hydrocarbon contaminants such as DDT, via sewage outfalls permitted offshore barging occurred for most last century. This study compiled database existing sediment fish DDT measurements to examine how this unique legacy...
Abstract River flows change on timescales ranging from minutes to millennia. These vibrations in flow are tuned by diverse factors globally, for example, dams suppressing multi‐day variability or vegetation attenuating flood peaks some ecosystems. The relative importance of the physical, biological, and human influencing is an active area research, as related question finding a common language describing overall regime. Here, we addressed both topics using daily river discharge data set over...
Pacific salmon (Oncoryhnchus spp.) and brown trout (Salmo trutta) are introduced species stocked in the Laurentian Great Lakes. In their native range, deliver material that enhances growth, alters isotopic ratios, increases contaminant burdens of resident fish. However, whether subsidies mediate interactions between competing is unknown. Here, we employed a mesocosm experiment simulation model to determine if tissue consumption influences brook (Salvelinus fontinalis) mercury concentrations...

River flow changes on timescales ranging from minutes to millennia. These variations influence fundamental functions of ecosystems, including biogeochemical fluxes, aquatic habitat, and human society. Efforts describe temporal variation in river flow—i.e. regime—have resulted hundreds unique descriptors, complicating interpretation identification global drivers overall regime. In this study, we used three analytical approaches investigate related questions: 1. how interrelated are regime...

These variations influence fundamental functions of ecosystems, including biogeochemical fluxes, aquatic habitat, and human society. Efforts describe temporal variation in river flow—i.e., flow regime—have resulted hundreds unique descriptors, complicating interpretation identification global drivers dynamics. Here, we used a cross-disciplinary analytical approach investigate two related questions: 1. Is there...
