Fig. 4: Predicted diversity changes of overall fish species richness (SR) and richness of fish species of conservation concern (SPCC) due to LULC changes in the periods of 1992–2016 (past) and 2016–2050 (future).
From: Terrestrial land cover shapes fish diversity in a major subtropical river catchment
Future prediction of LULC was adopted from GLIOBIO4 data, and the list of seven SPCC was derived from the Red List of the International Union for Conservation of Nature (IUCN) with alien or invasive fish species removed (Table S1). We observed croplands and urban areas expansion over the past (a) and future (d) periods, resulting in a reduction of natural habitats such as forest, shrub, and grassland, especially in the mountainous region in the period of 2016–2050. Projected percentages of overall fish species change between 1992 and 2016 (b), and between 2016 and 2050 (e). Projected numbers of SPCC change between 1992 and 2016 (c), and between 2016 and 2050 (f). These predictions demonstrate different trends of fish species richness change between overall fish species richness and SPCC richness. Please refer to Fig. S8 for other scenarios SSP1RCP26, SSP3RCP60.
