Polar.coordinates {EnvNicheR}

Polar cooordinates obtained from the function Niche

Description

Polar cooordinates.CSV file obtained from the function Niche using presence data of terrestrial carnivores of the family Felidae and mean of environmental variables in cells of 1 degree x 1 degree around the world.

Usage

data(Polar.coordinates)

Format

A matrix with the taxonomy, polar coordinates and mean values of the environemntal variables for each polar coordinate.

Source

The range maps of the species were obtained from the International Union for Conservation of Nature (IUCN) at the web page https://www.iucn.org/. The data of the mean annual temperature (BIO1), isothermality (BIO3), temperature seasonality (BIO4) and mean annual precipitation (BIO12) were downloaded from the web https://www.worldclim.org/. Both range maps and environmental variables were inputted into ModestR and the output file was used in the function Niche() and the file Polar coordinates.CSV obtained was converted to a RData file.
