is a locoweed of northwest China that can seriously impede livestock development. However, it also plays various ecological roles, such as wind protection and sand fixation. Here, we used an optimized MaxEnt model to predict the distribution of suitable habitat of under current (1970-2000) conditions and future (2021-2080) climate change scenarios based on recent occurrence records. The most important environmental variables (suitability ranges in parentheses) affecting the distribution of were average maximum temperature of February (-2.12-5.34C), followed by total precipitation of June (2.06-37.33 mm), and topsoil organic carbon (0.36-0.69%). The habitat suitability of was significantly correlated with the frequency of livestock poisoning ( < 0.05). Under current climate conditions, the suitable environment of was distributed in central and western Inner Mongolia, Ningxia, central and northwestern Gansu, central and northwestern Qinghai, and the four basins around the Tianshan Mountains in Xinjiang. Under future climate conditions, the suitable habitat of shifted to higher latitudes and altitudes. No previous studies have used niche models to predict the suitable environment of this species nor analyzed the relationship between the habitat suitability of poisonous plants and the frequency of animal poisoning. Our findings provide new insights that will aid the prevention of livestock animal poisoning and the control of poisonous plants, promote the development of the livestock husbandry industry, and provide basic information that will facilitate the maintenance of the ecological balance of grassland ecosystems.
是中国西北的一种疯草，会严重阻碍畜牧业发展。然而，它也发挥着各种生态作用，如防风固沙。在此，我们基于最近的出现记录，使用优化的MaxEnt模型预测了当前（1970 - 2000年）条件下以及未来（2021 - 2080年）气候变化情景下[该疯草名称未给出]适宜栖息地的分布。影响[该疯草名称未给出]分布的最重要环境变量（括号内为适宜范围）是2月平均最高温度（-2.12 - 5.34℃），其次是6月总降水量（2.06 - 37.33毫米）和表层土壤有机碳（0.36 - 0.69%）。[该疯草名称未给出]的栖息地适宜性与牲畜中毒频率显著相关（<0.05）。在当前气候条件下，[该疯草名称未给出]的适宜环境分布在内蒙古中西部、宁夏、甘肃中北部、青海中北部以及新疆天山山脉周边的四个盆地。在未来气候条件下，[该疯草名称未给出]的适宜栖息地向更高纬度和海拔转移。此前没有研究使用生态位模型预测该物种的适宜环境，也没有分析有毒植物的栖息地适宜性与动物中毒频率之间的关系。我们的研究结果提供了新的见解，将有助于预防牲畜中毒和控制有毒植物，促进畜牧业发展，并提供有助于维持草原生态系统生态平衡的基础信息。
