Initial interactive map of the suitability for the target 6 root-knot nematode (RKN) species (Meloidogyne incognita, M. javanica, M. arenaria, M. enterolobii, M. ethiopica & M. luci).This interactive map on RKN species richness, was developed from the sum of the 6 individual binary maps of suitability based on the threshold of maximum training sensitivity plus specificity (MTSS) using the ensemble species distribution models (SDMs) based on soil bioclimatic predictor variables (https://doi.org/10.1111/gcb.16060) as well as soil-physico-chemical variables such as soil organic carbon content, pH, and cation exchange capacity (obtained from soilgrids datasets, https://soilgrids.org/). These richness maps showing the potential or predicted suitable areas (grid cells of the agricultural landscapes (at 3 km * 3 km spatial resolution). This richness map indicates the potential RKN invasion risk or emergence risk, and doesn’t provide information at the level of specific RKN species. This map can be used as decision-support tool for field survey or sampling, management prioritization of the agricultural landscape and guide the range-shift strategy of the economic crops according to the cropland areas (grid cells) at high or low potential risk.

Initial interactive map of the suitability for target 3 tropical root-knot nematode
(RKN) species richness (Meloidogyne incognita, M. javanica, M. arenaria). This map of RKN richness was developed similarly to the above, and this showing the potential or predicted suitable areas (grid cells of the agricultural landscapes (3 km * 3 km spatial resolution). This richness map indicates the potential invasion risk or emergence risk and doesn’t provide information at the level of specific RKN species. This map can be used as decision-support tool for field survey or sampling, management prioritization of the agricultural landscape and guide the range-shift strategy of the economic crops according to the cropland areas (grid cells) at high or low potential risk.
