Data for Modeling the potential distribution of Wesselsbron, Sindbis, and Middelburg viruses and their vectors in Africa under future climatic and land-use changes

This dataset comprises ecological variables and species presence points used to model the current and future potential distribution of Wesselsbron, Sindbis, and Middelburg viruses and five mosquito vectors (Aedes circumluteolus, Aedes mcintoshi, Culex univittatus, Culex pipiens and Mansonia Africana). Ecological data include 19 Bioclimatic variables, Normalized Difference Vegetation Index, Built-Up areas, Settlement model grid, Human population, Forested areas, Livestock density, and Croplands. Two time periods were selected, current (reference year 2015) and future (2021 – 2040); current bioclimatic comprised data collected over 1970 – 2000. For the future, we utilized the Intergovernmental Panel on Climate Change’s Shared Socioeconomic Pathways (SSPs), which are projections of future greenhouse gas emissions and climate. We chose SSP2-4.5 for moderate and SSP5-8.5 for severe conditions. Based on the Coupled Model Intercomparison Project Phase 6, we selected two Global Climate Models (GCM), IPSL - CM6A - LR and HadGEM - GC31 – LL. Therefore, per GCM, we extracted ecological data for the two SSPs for the period 2021 – 2040. Presence points comprise coordinates of locations of samples from which the species were previously identified.

本数据集包含用于构建韦塞尔斯布朗病毒、辛德毕斯病毒（Sindbis virus）、米德尔堡病毒以及5种蚊媒——淡色伊蚊（Aedes circumluteolus）、麦氏伊蚊（Aedes mcintoshi）、单纹库蚊（Culex univittatus）、尖音库蚊（Culex pipiens）和非洲曼蚊（Mansonia Africana）——当前与未来潜在分布模型的生态变量及物种存在点数据。生态数据涵盖19个生物气候变量（Bioclimatic variables）、归一化差异植被指数（Normalized Difference Vegetation Index）、建成区、居民点模型网格、人口总量、林区、牲畜密度与农田数据。研究选取两个时间周期：当前时段（参考年份为2015年，其生物气候数据采集时段为1970-2000年）与未来时段（2021-2040年）。针对未来情景，本研究采用了政府间气候变化专门委员会（Intergovernmental Panel on Climate Change, IPCC）提出的共享社会经济路径（Shared Socioeconomic Pathways, SSPs）——该路径用于预测未来温室气体排放与气候状况——并选取SSP2-4.5代表中度情景、SSP5-8.5代表极端情景。基于第六次耦合模式比较计划（Coupled Model Intercomparison Project Phase 6, CMIP6），本研究选取了两款全球气候模型（Global Climate Models, GCM）：IPSL-CM6A-LR与HadGEM-GC31-LL。因此，针对每一款全球气候模型，我们均提取了2021-2040年间对应两条共享社会经济路径下的生态数据。物种存在点数据包含此前已完成物种鉴定的采样点位坐标。
