Abstract
Spatio-temporal analysis of mast-eating small mammal populations at a continental scale using box-trapped small mammal data obtained from the National Ecological Observatory Network (NEON). This dataset submission includes a small mammal data file with metadata, a climate-data data file with metadata, and R code used for analysis that supports conclusions made in the manuscript titled "An ecological dipole in North American mast-eating small mammal dynamics" by Barton et al., for publication in Ecology and Evolution.
Dataset DOI: 10.5061/dryad.tdz08kqbm
Description of the data and file structure
Small mammal box-trapping data is publicly available and was downloaded from the National Ecological Observatory Network (NEON), then transformed into the small mammal index used in this study (# unique small mammals/trapnight/year); ("standardized_df_august2023.csv"). Weather data is publicly available from daymet.ornl.org, and provided here ("Weather_Wide_2009_2021_jan24.csv") to facilitate reproducibility of R analyses.
Files and variables
File: mammalmanuscript_code.R
Description: R file with reproducible code for analyses used to make conclusions in the manuscript.
File: standardized_df_august2023.csv
Description: Number of small mammals per trapnight per year per NEON site, with values for all species at a site. Missing values for any site/species/year combination are indicated with "NA".
Variables
- siteID: the four letter site code of National Ecological Observatory Network (NEON) field sites
- lat: latitude in decimal degrees of the geographic location of specified NEON site
- lon: longitude in decimal degrees of the geographic location of specified NEON site
- scientificName: scientific name of mast-eating small mammal species
- Y2013, Y2014, Y2015...: year of data collection
File: Weather_Wide_2009_2021_jan24.csv
Description: Raw climate indices obtained from daymet.ornl.org. File format is wide to accommodate data manipulation; for simplicity, all columns are not defined here, but only the first and last column of each climate variable.
Variables
- SITENAME: the four letter site code of National Ecological Observatory Network (NEON) field sites
- LAT: latitude in decimal degrees of the geographic location of specified NEON site
- LON: longitude in decimal degrees of the geographic location of specified NEON site
- TILE: daymet tile number of named location
- ELEVATION_m: elevation in meters of specified NEON site
- MeanTmean_C.month.Jan.2009...2022: mean January temperature in degrees Celsius from 2009-2022
- MeanTmean_C.month.Jul.2009...2022: mean July temperature in degrees Celsius from 2009-2022
- Totalprcp_mm.month.Jan.2009...2022: total January precipitation in mm from 2009-2022
- Totalprcp_mm.month.Jun.2009...2022: total June precipitation in mm from 2009-2022
