Abstract

ABSTRACT Although species are continually exposed to variations in climate over time, there is growing concern about the accelerated pace of climate change to which they are currently exposed, as climate is determinant in the geographic distribution of animals and plants. This study evaluated the climatic niche and impact of climate change in the 2061-2080 period on areas of occurrence of indicator tree species of alluvial forests in the south-central portion of the Atlantic Forest and Brazilian Pampa. Nineteen climatic variables were considered for the contemporary and future climates. The species’ climatic niches were modeled using the Maxent algorithm. Climatic adequacy for species in the Parana-Uruguay group was strongly influenced by variables related to temperature, while adequacy for species in the Atlantic group was related to rainfall and temperature. A decrease in the area of climatic adequacy is estimated for most species considered, with similar behavior in the two groups assessed. The species tend to occupy a more southern position, using areas of higher altitude, latitude and proximity to the Brazilian coast as climate refuges, highlighting these areas as strategic for environmental conservation.

气候变化背景下大西洋森林和潘草原冲积林的树种

随着时间的推移，物种持续暴露于气候变化中，但由于气候在动植物的地理分布中起着决定性作用，人们越来越关注它们目前所暴露的气候变化的加速速度。本文评价了2061-2080年气候变化对大西洋森林中南部和巴西潘帕草原冲积林指示树种分布区的生态位和影响。19个气候变量被考虑为当代和未来的气候。该物种的气候生态位是用Maxent算法建模的。巴拉圭-乌拉圭类群物种的气候适足性受到与温度有关的变量的强烈影响，而大西洋类群物种的气候适足性则与降雨和温度有关。据估计，所考虑的大多数物种的气候适宜性面积都有所减少，所评估的两组物种的行为相似。该物种倾向于占据更南部的位置，利用海拔更高、纬度更高、靠近巴西海岸的地区作为气候避难所，强调这些地区对环境保护具有战略意义。
