Abstract
Diversification and demographic responses are key processes shaping species evolutionary history. Yet we still lack a full understanding of ecological mechanisms that shape genetic diversity at different spatial scales upon rapid environmental changes. In this study, we examined genetic differentiation in an extremophilic grass Puccinellia pamirica and factors affecting its population dynamics among the occupied hypersaline alpine wetlands on the arid Pamir Plateau in Central Asia. Using genomic data, we found evidence of fine-scale population structure and gene flow among the localities established across the high-elevation plateau as well as fingerprints of historical demographic expansion. We showed that an increase in the effective population size could coincide with the Last Glacial Period, which was followed by the species demographic decline during the Holocene. Geographic distance plays a vital role in shaping the spatial genetic structure of P. pamirica alongside with isolation-by-environment and habitat fragmentation. Our results highlight a complex history of divergence and gene flow in this species-poor alpine region during the Late Quaternary. We demonstrate that regional climate specificity and a shortage of nonclimate data largely impede predictions of future range changes of the alpine extremophile using ecological niche modeling. This study emphasizes the importance of fine-scale environmental heterogeneity for population dynamics and species distribution shifts.

Description: These files store genetic information on the single nucleotide polymorphism markers (SNPs) in Puccinellia pamirica. The datasets were generetad by Genome-Wide Restriction Fragment Analysis via the DArTseq platform (Diversity Arrays Technology Pty Ltd, Canberra, Australia), which combines complexity reduction methods, fragment size selection, and high-throughput sequencing, optimised for a target organism.
Usage notes: We used R (version 4.2.2, 2022-10-31; https://www.R-project.org/) and RStudio (version 2022.07.2+576 "Spotted Wakerobin" Release (e7373ef832b49b2a9b88162cfe7eac5f22c40b34, 2022-09-06; http://www.rstudio.com/) on Windows 8.1 to handle these files. We used the dartR R-package (version 2.7.2) with necessary dependencies to import, proccess and analyse these data files as objects of a class genlight (dartR) in the R environment. You may also handle these files as objects of a class genlight using the adegenet and ade4 R-packages.

C. Customised map of water bodies in the Pamir Mountains
13) Central_Asia_water_polygonst.cpg - optional file 14) Central_Asia_water_polygonst.dbf - mandatory file - attribute format 15) Central_Asia_water_polygonst.prj - optional file 16) Central_Asia_water_polygonst.sbn - optional file 17) Central_Asia_water_polygonst.sbx - optional file 18) Central_Asia_water_polygonst.shp - mandatory file (main file) - shape format 19) Central_Asia_water_polygonst.shp.xml - optional file 20) Central_Asia_water_polygonst.shx - mandatory file - shape index format
Description: These files represent a customised map of water bodies and wetlands in the Pamir Mountains. We used OpenStreetMap waterway polygon layer of the studied area [https://www.openstreetmap.org; accessed via https://data.humdata.org/dataset/ with a keyword “Waterways” and country names] to assemble a layer of water bodies and wetlands in the studied area. We used files: hotosm_tjk_waterways_polygons_shp.zip (Tajikistan), hotosm_kgz_waterways_polygons_shp.zip (Kyrgyzstan), hotosm_kaz_waterways_polygons_shp.zip (Kazakhstan), hotosm_chn_west1_waterways_polygons_shp.zip (north-western China), hotosm_tkm_waterways_polygons_shp.zip (Turkmenistan), hotosm_uzb_waterways_polygons_shp.zip (Uzbekistan), hotosm_afg_waterways_polygons_shp.zip (Afghanistan), and hotosm_pak_waterways_polygons_shp.zip (Pakistan). We created the dataset in Esri ArcMap 10.8. More information about how we used this dataset in our analyses can be found in Appendix_S6_Maxent_Ecological_Niche_Modelling.docx.
Usage notes: This dataset is in Esri shapefile format for geographic information system (GIS) software. Shapefile is composed of mandatory files (extension: SHP, SHX and DBF) and optional files (extension: PRJ, XML, SBN, CPG and SBX). At least mandatory files should be downloaded and placed in one folder to access data stored in the main file (extension: SHP). The shapefile may be opened by means of the Esri software (ArcGIS, ArcMap) or may also be imported and visualised in the R environment. For example, we used the rgdal R-package (version 1.6-2) with the sp R-package (version 1.5-1) to visualise data using commands:
shp<-rgdal::readOGR("D:/Path_to_folder/Central_Asia_water_polygonst.shp")
plot(shp)D. Ecological niche modelling - Environmental leyers and model outputs
Files 21-86 with .asc extension
Description: The input raster layers and results (outputs) of the ecological niche (species distribution/habitat suitability) modelling under current, Last Glacial Maximum ~20-25 ka or future (~2070) conditions. We performed niche modelling using MaxEnt (version 3.4.4). See Appendix_S6_Maxent_Ecological_Niche_Modelling.docx to learn more about variables, variable selection procedure, model settings and model interpretation.
Usage notes: The files are in the ASCII format (extension: .asc) that could be handled by the Esri software or in the R environment. For example, we used the raster R-package (version 3.6-11) with the sp R-package (version 1.5-1) to visualise data using commands:
data<-raster("File_name.asc")
plot(data)E. Input dataset to Linear Mixed-Effects models (Landscape Genetics)
87) LME_models_input_dataset.csv Description: This is the input file including all the variables used for the Linear Mixed-Effects models. See Supplementary Appendix S8 for more details regarding LME models. Usage notes: The dataset is a comma separated file (.csv) and could be viewed e.g. in Microsoft Excel or in Notepad++. We performed Linear Mixed-Effects models using the lme4 (version 1.1-33), lmerTest (version 3.1-3), MuMIn (version 1.47.5) and partR2 (version 0.9.1.9000) R-packages.

Notes
Past projection to LGM was conducted using the most informative ENVIREM (http://envirem.github.io/#varTable) climatic variables in 2.5 arcminutes resolution based on the climate simulation of the Model for Interdisciplinary Research on Climate version 3.2 (MIROC; https://ccsr.aori.u-tokyo.ac.jp/~hasumi/miroc_description.pdf).
For future projections we used bioclimatic variables projected under three different atmospheric circulation models (MIROC-ESM, CCSM4 MPI-ESM) within Coupled Model Intercomparison Project Phase 5 (CMIP5). The raster layers were derived from the WORLDCLIM repository in 30 arcseconds resolution [http://www.worldclim.com/cmip5_30s] for 2070 (average for 2061-2080) under representative concentration pathways (RCPs) of 4.5 (intermediate CO2 emission scenario) and 8.5 (rising CO2 emission scenario).
