Climate change is recognized as an important threat to global biodiversity because it increases the risk of extinction of many species on the planet. Mexico is a megadiverse country and native tree species such as red cedar (Cedrela odorata) can be used to maintain forests while helping mitigate climate change, because it is considered a fast growing pioneer species with great economic potential in the forestry industry. In order to assess possible shifts in areas suitable for C. odorata plantations in Mexico with ecological niche models, we used the MaxLike algorithm, climate variables, the geo-referenced records of this species, three general circulation models and three scenarios of future emissions. Results show a current potential distribution of 573,079 km2 with an average probability of occurrence of 0.93 (± 0.13). The potential distribution area could increase up to 650,356 km2 by 2060 according to the general circulation model HADCM3 B2, with an average probability of occurrence of 0.86 (± 0.14). Finally, we delimited an area of 35,377 km2 that has a high potential for the establishment of C. odorata plantations, by selecting those sites with optimal conditions for its growth that are outside protected areas and are currently devoid of trees. C. odorata has a significant potential to help in the mitigation of the effects of climate change. Using MaxLike we identified extense areas in Mexico suitable to increase carbon sequestration through plantations of this highly valued native tree species.
气候变化被认为是全球生物多样性的一个重要威胁,因为它增加了地球上许多物种灭绝的风险。墨西哥是一个生物多样性大国,像红雪松(Cedrela odorata)这样的本地树种可以用来维持森林,同时帮助缓解气候变化,因为它被认为是一种生长迅速的先锋物种,在林业中有很大的经济潜力。为了评估墨西哥利用生态位模型种植红雪松的适宜地区可能发生的变化,我们使用了 MaxLike 算法、气候变量、该物种的地理参考记录、三个通用循环模型和三个未来排放情景。结果显示,目前的潜在分布面积为 573,079 平方公里,出现概率平均为 0.93(±0.13)。根据 HADCM3 B2 通用循环模型,到 2060 年,潜在分布面积可能增加到 650,356 平方公里,出现概率平均为 0.86(±0.14)。最后,我们划定了一个 35,377 平方公里的区域,这些区域有很高的种植红雪松的潜力,选择了那些生长条件最佳的地点,这些地点位于保护区之外,目前没有树木。红雪松在缓解气候变化影响方面具有重要潜力。我们使用 MaxLike 算法确定了墨西哥的大片地区适合通过种植这种高价值的本地树种来增加碳封存。
