These filesets support data from the following paper published in Diversity and Distributions:
Abundance and species diversity hotspots of tracked marine predators across the North American Arctic
DOI: 10.1111/ddi.12860
These filesets are GIS shapefiles (WGS84 projection) which contain the Getis-Ord Gi* analysis outputs for abundance densities and hotspots by species group and abundance and species diversity densities and hotspots across species groups by season.
Species groups
"CP" - cetaceans and pinnipeds"SB" - seabirds"PB" - polar bears
Headings
"FID" - grid cell number
"Count_PTT" - number of unique individuals"Count_Spec" - number of unique species
"GiZScore" - Getis-Ord Z score"GiPValue" - Getis-Ord P-value"Gi_Bin" - statistically significant hotspots at a=0.90 (1), 0.95 (2) and 0.99 (3) levels. Statistically significant coldspots at a=0.90 (-1), 0.95 (-2) and 0.99 (-3) levels. A score of 0 is non-significant.
