Percent contribution and permutation importance of environmental variables retained in a predictive approach to mapping Angiostrongylus cantonensis nematode distribution, Canary Islands, Spain*

Variable % Contribution Permutation
Precipitation seasonality 52.1 9.6
Mean annual temperature 18.1 49.8
Topographic wetness index 10.4 9.4
Terrain ruggedness index 9.5 20.3
Tree cover density, 2018 8.4 0.9
Mean NDVI (SD), 2022 0.8 (0.5) 1.6 (0.4)
Temperature seasonality 0.4 7.9

*Predictions of habitat suitability (probability of occurrence) were made in MaxEnt mode on the basis of data from A. cantonensis field surveys conducted on Tenerife in 2022. We used bioclimatic variables from the CHELSA database (https://www.chelsa-climate.org) for 1981–2010 (37), including annual mean temperature in degrees Celsius (bio1), temperature seasonality (bio4), annual precipitation in kilograms per square meter (bio12), and precipitation seasonality (bio15). NDVI, normalized difference vegetation index.
