Summary

Abstract

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 Attribute / Type Description
STREAM
VARCHAR2 		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.
YEAR
NUMBER 		Calendar year samples were collected. Units for values are Date.
Date_collected
DATE 		Date samples were collected in the field. Units for values are Date.
REACH
NUMBER 		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.
taxa_name
VARCHAR2 		Common or scientific name of taxa collected for isotope processing. Units for values are na.
trophic_level
VARCHAR2 		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.
Sample_Weight_g
NUMBER 		The weight in grams of the sample analyzed for isotope. Units for values are Grams.
Weight_%_C_MS
NUMBER 		The concentration percent of carbon (C) in each sample. Units for values are Percentage.
Weight_%_N_MS
NUMBER 		The concentration percent of nitrogen (N) in each sample. Units for values are Percentage.
delta_13C_per_mil
NUMBER 		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.
delta_15N_per_mil
NUMBER 		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.
fish_length (mm)
NUMBER 		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.
fish_weight (g)
NUMBER 		Fish weight in grams using a Mettler field balance of each fish analyzed for stable isotopes. Units for values are grams.
