36827 Cedar River N and C Isotopes 2000-2001 Entity Published / External 17861 Isotopes - Recolonization of the Cedar River, WA by Pacific salmon Data Set Planned These data consist of natural abundance levels of C and N stable isotopes in periphyton, in-stream leaf detritus, leaves of riparian plants, benthic invertebrates, and resident fish collected from multiple locations from the main stem Cedar River, and tributaries including Rock and Taylor creeks. Data were collected in 2000 and 2001 to establish baseline conditions before reintroduction of Pacific salmon in 2003. Data were analyzed at the University of Georgia Stable Isotope Facility.

Data were analyzed at the University of Georgia Stable Isotope Facility. 1 STREAM VARCHAR2 No No Active Name of sample location including:CR or main stem Cedar River between the dam and Cedar Falls; TC or Taylor Creek located above the dam; RC or Rock Creek located above the dam. Units for values are na. VARCHAR2 na na 2 YEAR NUMBER No No Active Calendar year samples were collected. Units for values are Date. NUMBER Date 2000 or 2001 3 Date_collected DATE No No Active Date samples were collected in the field. Units for values are Date. DATE Date See file 4 REACH NUMBER No No Active Unique geomorphic units defined by stream gradient, channel confinement, and dominant substrata. For additional details on reach designations see Kiffney, P.M., G. Pess*, J. Anderson*, P. Faulds, K. Burton and S. Riley. 2009. Changes in fish communities following recolonization of the Cedar River, WA, USA by Pacific salmon after 103 years of local extirpation. River Research and Applications 25: 438-452. Units for values are na. NUMBER na 1 through 10 5 taxa_name VARCHAR2 No No Active Common or scientific name of taxa collected for isotope processing. Units for values are na. VARCHAR2 na na 6 trophic_level VARCHAR2 No No Active Trophic levels of sample including leaves collected from plants (see Wikipedia for latin names) within 5 m of the stream edge, biofilm (slimy coating growing on stream rocks consists of bacteria, algae, and other organic matter), invertebrates (either nymphs or larvae; no adults or pupae) and resident (non-anadromous) fish. Fish caught by angling or electrofishing. Cottidae comprised mostly of torrent (Cottus rhotheus) sculpin with ~ 3 % riffle sculpin (C. gulosa). Rainbow trout = Oncorhynchus mykiss; cutthroat trout = O. clarkii clarkii. Trout fry were too small to be defined as cutthroat or rainbow. Units for values are na. VARCHAR2 na na 7 Sample_Weight_g NUMBER No No Active The weight in grams of the sample analyzed for isotope. Units for values are Grams. NUMBER Grams 0.1 through 2.0 8 Weight_%_C_MS NUMBER No No Active The concentration percent of carbon (C) in each sample. Units for values are Percentage. NUMBER Percentage 0 through 100 9 Weight_%_N_MS NUMBER No No Active The concentration percent of nitrogen (N) in each sample. Units for values are Percentage. NUMBER Percentage 0 through 100 10 delta_13C_per_mil NUMBER No No Active The concentration in per mil (parts per thousands) of C13 in each sample. Studies examining stable isotopes at or near natural abundance levels are usually reported as delta, a value given in parts per thousand or per mil ("o/oo"). Delta values are not absolute isotope abundances but differences between sample readings and one or another of the widely used natural abundance standards which are considered delta = zero (e.g. air for N, At%15N = 0.3663033; Pee Dee Belemnite for C, At%13C = 1.1112328). Isotope samples with no value and "." are samples with concentrations beyond the standard values so could not be determining. Units for values are per mil or parts per thousand. NUMBER per mil or parts per thousand -10 through -40 per mil 11 delta_15N_per_mil NUMBER No No Active The concentration in per mil (parts per thousands) of N15 in each sample. Studies examining stable isotopes at or near natural abundance levels are usually reported as delta, a value given in parts per thousand or per mil ("o/oo"). Delta values are not absolute isotope abundances but differences between sample readings and one or another of the widely used natural abundance standards which are considered delta = zero (e.g. air for N, At%15N = 0.3663033; Pee Dee Belemnite for C, At%13C = 1.1112328). Isotope samples with no value and "." are samples with concentrations beyond the standard values so could not be determining. Units for values are per mil or parts per thousand. NUMBER per mil or parts per thousand -10 through 25 per mil 12 fish_length (mm) NUMBER No No Active Fish length (fork for salmonids; total length for sculpin) in millimeters of each fish analyzed for stable isotopes. Fish were measured with handmade measuring board. Units for values are millimeter. NUMBER millimeter 1 through 600 mm 13 fish_weight (g) NUMBER No No Active Fish weight in grams using a Mettler field balance of each fish analyzed for stable isotopes. Units for values are grams. NUMBER grams 0.5 through 1000 grams gov.noaa.nmfs.inport:36827 Jeffrey Cowen 2017-02-16T19:24:58 SysAdmin InPortAdmin 2022-08-09T17:11:17 2018-02-27 Northwest Fisheries Science Center NWFSC 2725 Montlake Boulevard East Seattle WA 98112 USA 206-860-3200 https://www.nwfsc.noaa.gov 1001 Public No 2018-02-27 1 Year 2019-02-27
