Invasive exotic plants may compromise the survival, growth, and reproduction of native species and are among the leading causes of worldwide biodiversity losses. Climate changes—which will affect species distribution—may even amplify the problems caused by invasive species. Here, we used ecological niche models to evaluate the current and future distribution of 108 invasive plants in the entire Brazilian territory and the country's conservation unit facilities (CUFs). Overall, our results did not indicate a significant change in the potential distribution of invasive plants between the current and future climate scenarios, although we expect that 67.5% of the species will decrease its range in Brazil in the future. The proportion of the plants' invasive range inside conservation units varied from 1 to 12%, and results suggest that this would not increase or decrease in the future. Taken together, our results do not indicate that climate change will amplify the effects of existing invasive plants—although it may facilitate the invasion of other species. Both current and future scenarios suggest high suitability for invasive plants in the southern, southern, southeastern, and eastern coast of Brazil, comprising the Caatinga, Cerrado, and Mata Atlântica Brazilian biomes, the most populated areas of the country. We advise that conservation unit managers and authorities within these regions should continuously monitor such invasive plants to take early responses to avoid their establishment.

巴西的入侵植物:气候变化影响和保护单位内适当区域的发现

外来入侵植物可能会损害本地物种的生存,生长和繁殖,并且是全球生物多样性丧失的主要原因之一。气候变化将影响物种分布,甚至可能加剧由入侵物种引起的问题。在这里,我们使用生态位模型来评估整个巴西领土上的108种入侵植物的当前和未来分布以及巴西的保护单位设施(CUF)。总体而言,尽管我们预计未来有67.5%的入侵物种将缩小其在巴西的分布范围,但我们的结果并未表明当前和未来气候情景之间的入侵植物潜在分布的重大变化。植物在保护单元内的入侵范围所占比例从1%到12%不等,结果表明,这种情况将来不会增加或减少。两者合计,我们的结果并未表明气候变化会扩大现有入侵植物的影响,尽管它可能会促进其他物种的入侵。当前和未来的情况都表明,巴西南部,南部,东南部和东部沿海地区的入侵植物非常适合,其中包括巴西人口最多的Caatinga,Cerrado和MataAtlântica巴西生物群落。我们建议这些区域内的保护部门经理和主管部门应持续监视此类入侵植物,以便尽早采取措施,避免其入侵。我们的结果并不表明气候变化会扩大现有入侵植物的影响,尽管它可能会促进其他物种的入侵。当前和未来的情况都表明,巴西南部,南部,东南部和东部沿海地区的入侵植物高度适合,其中包括巴西人口最多的Caatinga,Cerrado和MataAtlântica生物群落。我们建议这些区域内的保护部门经理和主管部门应持续监视此类入侵植物,以便尽早采取措施,避免其入侵。我们的结果并不表明气候变化会扩大现有入侵植物的影响,尽管它可能会促进其他物种的入侵。当前和未来的情况都表明,巴西南部,南部,东南部和东部沿海地区的入侵植物非常适合,其中包括巴西人口最多的Caatinga,Cerrado和MataAtlântica巴西生物群落。我们建议这些区域内的保护部门经理和主管部门应持续监视此类入侵植物,以便尽早采取措施,避免其入侵。以及巴西人口最多的地区马塔亚特兰蒂卡(MataAtlântica)巴西生物群落。我们建议这些区域内的保护部门经理和主管部门应持续监视此类入侵植物,以便尽早采取措施,避免其入侵。以及巴西人口最稠密的地区MataAtlântica巴西生物群落。我们建议这些区域内的保护部门经理和主管部门应持续监视此类入侵植物,以便尽早采取措施,避免其入侵。
