Hydrodynamic processes can lead to the accumulation and/or dispersal of water column constituents, including sediment, phytoplankton, and particulate detritus. Using a combination of field observations and stable isotope tracing tools, we identified how hydrodynamic processes influenced physical habitat, pelagic communities, and food web structure...

White Sturgeon (Acipenser transmontanus), a species of concern in the San Francisco Estuary, is in relatively low abundance due to a variety of factors. Patton et al. sought identify the estuarine habitat used by White Sturgeon to aid in the conservation and management of the species locally and across its range. By seasonally sampled sub-adult and...

Clear Lake Hitch is an imperilled minnow endemic to Clear Lake, Lake County, California, United States listed as threatened under the California Endangered Species Act (ESA) and a candidate for listing under the United States ESA. It exhibits a potamodromous life cycle whereby adults, which reach up to 6 + years in age and over 350 mm in length, mi...

... The factors governing primary production in terminal channels, where water exchange rates are low and age of water increases, are complex Cloern 2007;Downing et al. 2016), with important implications for energetic source-sink dynamics within the ecosystem (Malone et al. 1986;Crosswell et al. 2017;Wang et al. 2018). Despite their historic loss, terminal sloughs, with their habitat complexity, continue to provide important contributions to the food web for pelagic consumers in estuaries (Carle et al. 2020;Young et al. 2020). Although these habitats can support higher phytoplankton abundance than areas with faster water exchange rates (Stumpner et al. 2020a), the extent to which nutrient limitation may play a role in regulating phytoplankton remains unclear, especially in the context of transport processes that can be dominated by tidal hydrodynamics that vary at short timescales. ...
... In contrast, the extent of marine habitat use by white sturgeon is not known (Hildebrand et al., 2016). Aggregations of white sturgeon do occur in estuarine environments (Patton et al., 2020), but the species can complete its entire life cycle within a single river basin (Hildebrand et al., 2016). Adult green sturgeon are opportunistic consumers of benthic intertidal fauna (e.g., Neotrypaea californiensis), as well as subtidal crustaceans, bivalves, and fish (Dumbauld et al., 2008). ...
... We calibrated the cumulative energy BIW value to characterize the beginning of the hypoxic period, BIW c1 , for each basin and DO thr (Table 3). For example, mild and severe hypoxia and avoidance for fish have been defined when DO values are lower than 4 mg L −1 and 2 mg L −1 , respectively (Biddanda et al., 2018;Feyrer et al., 2020). The fish tolerance to hypoxia also changes with fish species. ...
