  1. The magnitude of terrestrial LULC effect of rainfed cropland, irrigated cropland, forest, shrub- and grassland (S. + G.), and urban areas, respectively, is provided. l is the log-likelihood function for optimization (see Supplementary Text). The significance of parameters is determined by a likelihood-ratio test (see “Materials and Methods” section and Supplementary Text). The uncertainty estimation is indicated in Table S8. We found a significant relative positive effect of rainfed cropland on fish species richness, but significant relative negative values of forest and urban areas across the Chao Phraya catchment.
