Expanding China's protected areas network to enhance resilience of climate connectivity

The code used for analysis, mammalian species occurrence points, prediction accuracy(AUC), and prediction distribution.

Specifically,

The main nodes are named "network efficiency.R" and "network efficiency_random.R", which can be run in RStudio software (download at https://posit.co/), and the files "hfp_expanded.csv" and "EN_length_expanded.net" are example data.

"Terrestrial mammalian species occurrence points.csv" is the latitude and longitude coordinates of occurrence records.

"AUC_prediction accuracy of Maxent.xlsx" is the prediction accuracy of each species in the Maxent model.

"all_species_maxent.zip" is the composite terrestrial mammalian species distribution of equal weight overlapping the spatial distribution of each species ("each_species_maxent.zip").
