We used spatiotemporal trends in production to identify the role of marine-derived nutrients in mediating these interactions. Among ocean upwelling-influenced estuaries along the northeastern Pacific, we documented a negative correlation between annual production of ulvoid macroalgae and the seagrass, Zostera marina L., at a regional scale that included four estuaries along a 400 km distance. While macroalgal biomass was , 30 times greater in southern (Yaquina Bay and Coos Bay, Oregon) compared to northern (Willapa Bay, Washington, and Netarts Bay, Oregon) estuaries, no temporal patterns of eelgrass decline were observed within the estuaries over a 5 yr period{\textellipsis}{\textquotedblright} (from the Abstract)}, month = {2013, May}, pages = {p,1103-1112}, keywords = {algae, Coos Bay, eelgrass = Zostera marina, Netarts Bay, nitrogen, phosphorus, primary production, Ulva spp., upwelling, Willapa Bay, Yaquina Bay}, doi = {doi:10.4319/lo.2013.58.3.1103}, author = {Hessing-Lewis, Margot L. and Hacker, Sally D.} }
