Abstract

ABSTRACT Astrocaryum aculeatum Mart. Moreover, Astrocaryum acaule Mart. are palm trees with ecological and extractive importance in the Amazon. These are hearty species that have been associated with archaeological sites and thrive in the presence of humans in certain areas. This work aimed to verify the effect of global climate change on the potential geographic distribution of A. acaule and A. aculeatum in the current period and future climate scenarios using ecological niche modeling in Brazilian phytogeographic domains. The modeling was based on 19 bioclimatic variables obtained from the Worldclim website and four algorithms (Climate space model, Envelope Score, Niche Mosaic, and Environmental Distance). Additionally, the Environmental Distance algorithm showed greater similarity regarding species distribution with potential occurrence in the five Brazilian domains (Amazon, Pantanal, Caatinga, Cerrado, and Atlantic Forest). The dispersion patterns were very similar between the two Astrocaryum palms though A. aculeatum was more sensitive to climatic variations. A. acaule may be more resilient to changes, as demonstrated by being able to recolonize in the southern portion of the Amazon in future scenarios in the year 2070. The modeling helped to delimit potential areas for A. aculeatum and A. acaule, indicating the need for the conservation of the species in more sensitive regions.

亚马逊地区棕榈树的地理分布与保护预测。和鹿茸。

摘要:星形姜。此外，Astrocaryum还能吸引顾客。是在亚马逊雨林中具有生态和采掘重要性的棕榈树。这些都是与考古遗址有关的丰盛物种，在某些地区人类存在的情况下茁壮成长。本研究旨在利用巴西植物地理域生态位模型，验证当前和未来气候情景下全球气候变化对A. acaule和A. acleatum潜在地理分布的影响。该模型基于从Worldclim网站获取的19个生物气候变量和4种算法(气候空间模型、包络评分、生态位马赛克和环境距离)。此外，环境距离算法在巴西5个域(亚马逊、潘塔纳尔、Caatinga、塞拉多和大西洋森林)的物种分布和潜在发生方面显示出更大的相似性。两种树间的分布模式非常相似，但对气候变化更为敏感。A. acaule可能对变化更有弹性，正如在2070年的未来情景中能够在亚马逊南部重新定居所证明的那样。该模型帮助划分了针叶草和针叶草的潜在生长区域，表明在更敏感的区域需要对该物种进行保护。
