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...

... -15‰) in the S. salsa and S. alterniflora habitats were lower than the values commonly observed in temperate waters (-22 to -20‰;Cresson et al., 2012). We hypothesize that our conservative estimates for the phytoplankton stable isotope signatures in the two habitats were either influenced by water salinity and dissolved inorganic carbon (Careddu et al., 2015) or due to the fact that the collected phytoplankton may reflect a combination of phytoplankton, microorganisms, and POM of undefined origins (Young et al., 2021). The lower d 13 C values for SOM in the higher-elevation P. australis habitat compared with the lower-elevation S. alterniflora and Z. japonica habitats are consistent with the findings of Park et al. (2017), and are also consistent with observations that the d 13 C values of POM in freshwater are significantly lower than those in saltwater (Dibble and Meyerson, 2014;Ye et al., 2017). ...
... We quantified life-long variation in exposure to salinity concentrations in White Sturgeon to reconstruct movements and habitat use in the SFE using fin ray Sr isotope ( 87 Sr/ 86 Sr) geochemistry. Although previous studies have described habitat use of White Sturgeon in the SFE using baited hooks, telemetry, and mark recapture techniques (Nelson et al., 2013;Miller et al., 2020;Patton et al., 2020), our study is the first to employ a natural geochemical tracer to examine the ontogenetic movements and habitat use patterns of over 100 individual White Sturgeon over their lifespan prior to capture. Our results largely corroborated prior observations of amphidromous migratory behaviors (Bemis and Kynard, 1997;Patton et al., 2020) with prolonged periods of estuarine residence (DeVore et al., 1999;Miller et al., 2020). ...
... 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. ...
