简介:我们使用了GIS和最大的熵预言六蛇种的潜在的分发在Kroumiria(西北的突尼斯)属于三个家庭:Natricidae(Natrixmaura和Natrixastreptophora),Colubridae(Hemorrhoishippocrepis,Coronellagirondica和Macroprotodonmauritanicus),和Lamprophiidae(Malpoloninsignitus)。为每种的合适的产地用最大的熵算法被建模,联合存在地数据(在16期间镇定?年:2000-2015)与一套七个环境变量(吝啬的年度降水,举起,斜坡坡度,方面,到水路的距离,陆地表面温度和规范的微分植被索引。这些环境变量的相对重要性被大折刀测试评估,我们的模型的预兆的力量在操作特征的接收装置下面用区域被估计。种类分发的主要解释变量是来自流和举起的距离,与分别地从60~77并且从10~25%的贡献。我们的学习提供了适用性在Kroumiria为蛇建模的第一个产地,这个信息能被担心在Kroumiria保存蛇的保存生物学家和陆地经理使用。
