摘要

物种分布模型是生物地理学和气候变化对生物多样性影响研究的一种分析工具。回顾了关键的建模概念和应用;描述了最大熵原理及其在Maxent软件中的实现。最后,以两种植物为例进行了物种建模:石竹科(Pycnophyllum spathulatum)和豆科(Prosopis pallida)。利用当前气候数据和基于RCP8.5的未来气候变化情景对这两个物种进行了建模,以研究全球变暖对物种分布的潜在影响。

Biogeografía predictiva: técnicas de modelamiento de distribución de especies y su aplicación en el impacto del cambio climático
Species distribution modeling is presented as an analytical tool for biogeography and the study of climate change impact on biodiversity.  Key modeling concepts and applications are reviewed; the maximum entropy principle is described as well as its implementation in the Maxent software.  Lastly, two demonstrative examples of species modeling are presented using two plant species: Pycnophyllum spathulatum (Caryophyllaceae) and Prosopis pallida (Fabaceae).  Bothe species were modeled using current climate data and under a future climatic change scenario based on RCP8.5 to examine the potential impact of global warming on the species’ distribution.
