*for raw and processed data, see shapefile #6 for associated watershed IDs corresponding with CSVs. Raw data are in files: 1. spp_matrix_bywtrshd.csv - Presence/absence matrix of species in watersheds included in the analysis. spp codes can be found in 'SCBD_byelevationcluster.csv' - Original data are from Provincial dataset: https://a100.gov.bc.ca/pub/fidq/viewMultipleWaterbodies.do 2. wtrshd_env_var_all_byelevationcluster.csv - All human pressure, environmental, and geospatial variables for watersheds in analysis, with elevation clusters identified. - Human pressure variables are all defined in Connors et al. 2018: https://salmonwatersheds.ca/library/lib_442/ - tlca (total land cover alteration), forest_dst (forest disturbance), imprv_srf (impervious surfaces), mines, linear_dev (linear development), road_den (road density), strm_x_den (stream crossing density), water_lic (water licenses), riprn_dst (riparian disturbance), waste_wtr (waste water), eca (equivalent clearcut area), i_d_defltn (insect & disease defoliation) - NISrich is number of non-native species within a watershed taken from the Provinical dataset referenced in #1 - elev_mean is mean elevation (m) - wtrshd_AreaKM2 is watershed area (square km) - UTMx.full and UTMy.full are UTMs of the centroids of the watersheds - CHELSA01 - CHELSA19 are averaged CHELSA variables for each watershed for the current normal period (V1.2) from: https://chelsa-climate.org/bioclim/ Processed data are in files: 3. LCBD_Simpson_byelevationcluster.csv - Local Contributions to Beta Diversity (Simpson) values by elevation cluster - Used to make Figures 4a and 5 (Iacarella et al. 2022, Diversity and Distributions) 4. CumulativeEffect_ISplineSumsbyWTRSHD_ZetaOrder2_LowElevationWtrshds.csv - Ispline values from MS-GDMs for Simpson, order 2, low elevation watersheds; scaled model variable values; Cumulative Effect score by watershed - Human pressure variable naming convention matches #2 and is from variables defined in Connors et al. 2018: https://salmonwatersheds.ca/library/lib_442/ - 'ispline' columns are the Ispline values from the low elevation MS-GDMs - 'rescal.v' columns are the rescaled human pressure value for each low elevation watershed (scaled by subtracting the minimum value and dividing by the difference of the maximum and minimum value) - 'CE.spline.sum' are the 'ispline' columns added together - Used to make Figures 4b and 5 (Iacarella et al. 2022, Diversity and Distributions) - Please contact author for additional Ispline values (Josephine.Iacarella@dfo-mpo.gc.ca). 5. SCBD_byelevationcluster.csv - Species Contributions to Beta Diveristy values for each species by elevation cluster - 'status' refers to whether the species is native or a species at risk (SAR) in British Columbia. - Used to make Figure 6 (Iacarella et al. 2022, Diversity and Distributions) Shapefile: 6. FRB_FWA_1to20K.shp - Shapefile of watershed polygons for the Fraser River Basin from the British Columbia Freshwater Atlas Assessment Watersheds (FWA) 1:20,000: https://www2.gov.bc.ca/gov/content/data/geographic-data-services/topographic-data/freshwater - 'wtrshd_fid' are the watershed IDs used in the CSVs above. Polygons associated with CSVs #3 and #4 were used to make Figure 4 (Iacarella et al. 2022, Diversity and Distributions)
