The scales of these two worlds are quite different: the freshwater environment works at the scale of a single stream, and environmental changes or stressors at the stream level affect a single population of fishes. On the other hand, oceanic changes or stressors cam affect broad regions or entire evolutionary significant units. By analyzing stock recruitment data for about sixty years along the Oregon Coast, some patterns become clear. Over this period, there have been significant changes in how fisheries are managed, from riparian buffers in forested lands to adding large woody debris to denuded streams. Despite these changes, it seems that oceanic conditions, especially the North Pacific Gyre Oscillation, which has dominated the marine environment since 1990, are determining population levels, rather than conservation efforts at the stream level. {\textquotedblleft}If Oregon Coast coho salmon populations become more synchronous, managers can expect to face new challenges driven by reductions in the population portfolio effect and increasingly variable marine conditions due to climate change{\textquotedblright} (from the Abstract).}, month = {2023,, May}, pages = {p.293-310}, keywords = {Alsea River, Beaver Creek, climate, Coho salmon = Oncorhynchus kisutch, ecosystem health, mathematical modeling, North Pacific Gyre Oscillation, Oregon Coast, Pacific Decadal Oscillation, population biology, Productivity, Salmon River Estuary, Siletz River, Siuslaw River, Umpqua River, Yaquina River}, doi = {https://doi.org/10.1111/fog.12630 }, author = {Davis, Melanie J. and Anthony, James and Ward, Eric J. and Firman, Julie and Lorion, Christopher} } @mastersthesis {83198, title = {Understanding Freshwater Mussel Distribution, Abundance, and Demography in the South Umpqua River Basin, Oregon: Impacts of Land Use and Stream Hydraulics}, year = {2021}, note = {Despite their many valuable ecosystem services and their threatened status, freshwater mussels are not well studied.
