Description of alternative ENMs

Description

A two-element list that describes 24 different ENMs used in simulations from Castilla et al. (2023).

Usage

data(enmScenarios)

Format

two element list (data frame and 24 element list)

Details

enms is a data frame with the following columns:

  • numRefugia. The number of spatially separated refugia at the LGM

  • gcm. The Global Circulation Model used in the ENM

  • ext. The buffer around occurrence points used to define background regions (in km)

  • algo. The niche modeling algorithm used in the model

  • threshold. The threshold used to define refuge cells, cells with suitability above this value at the LGM are occupied at the start of a simulation

  • cbi. Continuous Boyce Index - a measure of model accuracy, ranges from -1 to 1, with values >0 being better than random

  • tss. True Skill Statistic - a measure of model accuracy, ranges from -1 to 1, with values >0 being better than random

  • se. Sensitivity - proportion of present sites correctly predicted when the threshold is applied

  • sp. Specificity - proportion of absent sites correctly predicted when the threshold is applied

  • auc. The area under the curve - a measure of model accuracy, ranges from 0 to 1, with values >0.5 being better than random

  • meanRefugeAbund. Average habitat suitability of cells classified as refugia (given the defined threshold)

  • rasterStackName. A text string name for the ENM, describes GCM, extent, and algorithm used. Refers to landscapes located in system.file(package="holoSimCell","extdata/landscapes")

refugeCellNum is a list with 24 elements, 1 per ENM, with each element storing a vector of IDs for refuge cells. These ids correspond to the rasters named in 'rasterStackName' in the enms object
