Long-Term Trends in Summertime Habitat Suitability for Delta Smelt, Hypomesus transpacificus
San Francisco Estuary and Watershed Science, 2008 The biological productivity of river-dominated estuaries is affected strongly by variation in freshwater inflow, which affects nursery habitat quality. Previous research has shown this is generally true in the upper San Francisco Estuary, California, USA;
