Title: Biodiversity loss among global terrestrial vertebrate species
Abstract: This dataset is the assessment results of the paper “Future increase in aridity drives abrupt biodiversity loss among terrestrial vertebrate species” (under review) authored by Xiaoping Liu, Renyun Guo, Xiaocong Xu*, Qian Shi, Xia Li, Haipeng Yu, Yu Ren, and Jianping Huang. https://doi.org/10.1029/2022EF003162 <br> Four assessment indicators, i.e., exposure magnitude, exposure number, exposure abruptness, timing of abruptness, are available for the SSP5-8.5, SSP2-4.5, and SSP1-2.6 scenarios. <br> There are 8 files in each SSP scenario separate folder. They follow the same naming method, and the SSP585 Scenario folder is used as an example to illustrate what each file means. <br> ssp585_mag.tif: Exposure magnitude for all species in scenario SSP585. ssp585_num.tif: Exposure number for all species in scenario SSP585. ssp585_abr.tif: Exposure abruptness for all species in scenario SSP585. ssp585_time.tif: Exposure time for all species in scenario SSP585. <br> ssp585_mag_amphi.tif: Exposure magnitude for amphibian species in scenario SSP585. ssp585_mag_mamm.tif: Exposure magnitude for mammal species in scenario SSP585. ssp585_mag_bird.tif: Exposure magnitude for bird species in scenario SSP585. ssp585_mag_rep.tif: Exposure magnitude for reptile species in scenario SSP585. <br> Valid values for all indicators are non-negative. Note that there are special negative values in these raster files that you can simply ignore for your analysis. Here's what each of these negative numbers means: <br> -1 means that no specified species class exists at that location. <br> -0.7 means that less than half of the models have a value at this location and are therefore marked as not significant and not included in subsequent analyses. <br> -0.5 means that the Exposure number at this location is no more than 5. In order to avoid the influence of small samples on the analysis, they are not included in our subsequent analysis.
