Relative influence of environmental variables in boosted regression tree model used in a predictive approach to mapping Angiostrongylus cantonensis nematode distribution, Canary Islands, Spain*
| Variable | % Relative influence |
|---|---|
| Tree cover density | 30.95 |
| Precipitation seasonality | 22.19 |
| Temperature seasonality | 17.03 |
| Mean NDVI (SD) | 12.74 (6.88) |
| Mean annual temperature | 5.83 |
| Terrain ruggedness index | 3.21 |
| Annual precipitation | 0.79 |
| Topographic wetness index | 0.36 |
*Model used local prevalence of A. cantonensis nematode detection among multiple host groups across Tenerife on the basis of 2022 field surveillance data. NDVI, normalized difference vegetation index.
