Title: Cedar River N and C Isotopes 2000-2001
Short Name: Cedar River N and C Isotopes 2000-2001
Status: Planned
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 Attributes

Attribute Summary

Rubric Score Primary Key? Name Type Description
100
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.
100
YEAR NUMBER Calendar year samples were collected. Units for values are Date.
100
Date_collected DATE Date samples were collected in the field. Units for values are Date.
100
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.
100
taxa_name VARCHAR2 Common or scientific name of taxa collected for isotope processing. Units for values are na.
100
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.
100
Sample_Weight_g NUMBER The weight in grams of the sample analyzed for isotope. Units for values are Grams.
100
Weight_%_C_MS NUMBER The concentration percent of carbon (C) in each sample. Units for values are Percentage.
100
Weight_%_N_MS NUMBER The concentration percent of nitrogen (N) in each sample. Units for values are Percentage.
100
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.
100
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.
100
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.
100
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.
