Title Exact 100m
Downloaded 220 times
Description The file ‘Exact 100m.csv’ includes environmental covariates calculated within a 100 m radius buffer around the 32 whooping crane group locations obtained with a global positioning system as well as within a 100 m radius buffer around the 10,000 Monte Carlo integration points used in the analysis. The column ‘presence.location’ indicates if the covariates are associated with a location of a whooping crane group (yes) or a Monte Carlo integration point (no). Columns ‘aquatic’ and ‘development’ represent the proportion of aquatic habitat and development within a 100 m radius buffer around the whooping crane group locations and the Monte Carlo integration points. Columns ‘aquatic.section’ and ‘development.section’ represent the proportion of aquatic habitat and development within a 100 m radius buffer around whooping crane group locations that were degraded in accuracy to the section level and the Monte Carlo integration points. Columns ‘aquatic.small’ and ‘development.small’ represent the proportion of aquatic habitat and development within a 100 m radius buffer around whooping crane group locations that included a small degradation (σ = 100 m) in location accuracy and the Monte Carlo integration points. Columns ‘aquatic.large’ and ‘development.large’ represent the proportion of aquatic habitat and development within a 100 m radius buffer around whooping crane group locations that included a large degradation (σ = 1000 m) in location accuracy and the Monte Carlo integration points. The accuracies of the 10,000 Monte Carlo integration points were not degraded and thus the proportion of aquatic habitat and development within the 100 m radius buffers are the same across respective columns. Note: the same 10,000 Monte Carlo integration points were used in all analyses.

Description The file ‘Exact 500m.csv’ includes environmental covariates calculated within a 500 m radius buffer around the 32 whooping crane group locations obtained with a global positioning system as well as within a 500 m radius buffer around the 10,000 Monte Carlo integration points used in the analysis. The column ‘presence.location’ indicates if the covariates are associated with a location of a whooping crane group (yes) or a Monte Carlo integration point (no). Columns ‘aquatic’ and ‘development’ represent the proportion of aquatic habitat and development within a 500 m radius buffer around the whooping crane group locations and the Monte Carlo integration points.

Title Full 100m
Downloaded 23 times
Description The file ‘Full 100m.csv’ includes environmental covariates calculated within a 100 m radius buffer around the 32 whooping crane group locations obtained with a global positioning system, the 36 locations that were recorded as the center the Public Land Survey System section, and the 10,000 Monte Carlo integration points. The column ‘presence.location’ indicates if the covariates are associated with a location of a whooping crane group (yes) or a Monte Carlo integration point (no). Columns ‘aquatic’ and ‘development’ represent the proportion of aquatic habitat and development within a 100 m radius buffer around whooping crane group locations and Monte Carlo integration points. The column ‘accuracy’ indicates if the location was recorded as the center of a Public Land Survey System section (section) or if the location was recorded with a global positioning system (gps). The location of the 10,000 Monte Carlo integration points were recorded without error and therefore the ‘accuracy’ is recorded as exact. Note: the same 10,000 Monte Carlo integration points were used in all analyses.
