Abstract:

This dataset lists every sample that was collected in 2015 for the food web project within the Coastal Waters Consortium II. Each sample has been assigned a CWC ID Number and all information gathered at the time of collection is listed here (species name, collection date, site, etc). The samples include tissue samples of multiple consumers (fish, invertebrates, terrestrial vertebrates) as well as primary producers from salt marshes in southern Louisiana. The samples were collected using a variety of methods that are specified in the spreadsheet under “Gear”. All tissue samples were frozen at -80oC so they could be accessed at a later date for fatty acid [R4.x264.000:0014, R4.x264.000:0053], bulk stable isotope [R4.x264.000:0013, R4.x264.000:0054], and/or compound-specific stable isotope analyses. Fish stomachs were preserved in formalin so the contents could be identified and measured at a later date. Additional dataset authors are Olaf Jensen, Ken Able, Joel Fodrie, Michael Polito, Jill Olin, Jessica Johnson, Charles Martin, Brian Roberts, Nancy Rabalais, Linda Hooper-Bui, Sabrina Taylor, Philip Stouffer.

Purpose:

This dataset was developed to serve as a central location to list all the samples collected in 2015 as part of the food web project within the Coastal Waters Consortium II. Multiple researchers are using subsets of these samples for different purposes and types of analyses. The results of those different types of analyses are included in separate datasets, but this one is the only one that includes all the information associated with each sample at the time of collection. Therefore, it is a reference document for all other datasets associated with this project.

Data Parameters and Units:

CWC ID Number: code assigned by our group to every sample collected Other ID Number: code that may have been assigned by other groups who collected the sample Collection Date: month and year of collection Site: names assigned by our group to different marsh sites Latitude: in decimal degrees Longitude: in decimal degrees Habitat/Location (measurements in meters indicate distance from marsh edge): we use this parameter to identify where in the marsh (or relative to the marsh) the sample was collected. Gear: type of gear used to collect the sample Node Group: refers to the functional group the species belongs to according to a diet literature review performed as part of a food web study (McCann et al. in press) Node Code: short version of node group Common Name: generally used name Scientific Name: genus and species, or only genus when species is unknown n: number of individual animals that make up the sample Total Length (mm): in millimeters Fork Length (mm): in millimeters Carapace width (mm): in millimeters Weight (grams): in grams Sex: male, female, or not available (unidentified) Tissue Collected: type of tissue (whole body, muscle, stomach, liver, hepatopancreas, plant) collected Collection Notes: any additional information regarding collection, storage, or processing
