Shifting hotspots: Climate change projected to drive contractions and expansions of invasive plant abundance ranges

This file contains maps of current and future abundance suitable habitat for 144 invasive plant species in the United States. Each tiff file represents the current or future range prediction maps of habitat suitable for supporting abundant populations (greater than or equal to 5% cover) of 144 invasive plant taxa, projected across the lower 48 States of the United States. Each tiff file is named with the USDA species code (SpCode) (see 'Species_information.xlsx file for full species names), with species codes followed by .2c indicating maps related to future climatic conditions under a +2oC warming scenario. Areas predicted to be climatically suitable for supporting abundant populations is based on model agreement and range from 0 (no models identify that area as suitable) to 15 (all model outputs identify the area as suitable). Values of 300 represent areas that are masked due to climate dissimilarity. See main publication for model fitting details.

本数据集包含美国境内144种入侵植物物种当前及未来适宜生境丰度分布图。每份TIFF（Tagged Image File Format）文件均对应美国本土48州范围内，针对144种入侵植物类群的当前或未来适宜生境分布预测图，此类生境可支撑覆盖度≥5%的高密度种群。每份TIFF文件以美国农业部（USDA）物种代码（SpCode）命名（完整物种名称详见《Species_information.xlsx》文件），其后缀.2c代表该地图基于+2℃升温情景下的未来气候条件生成。预测可支撑高密度种群的气候适宜区取值范围为0至15，其中0代表无模型将该区域判定为适宜生境，15代表所有模型均将该区域判定为适宜生境。取值为300的区域代表因气候不相似性被掩膜的区域。模型拟合细节详见主出版物。
