R code for species distribution modeling in "Phylogeography of a widespread sub-Saharan murid rodent Aethomys chrysophilus: the role of geographic barriers and paleoclimate in the Zambezian bioregion."

Zipped R code and necessary data for MaxEnt species distribution modeling used in "Phylogeography of a widespread sub-Saharan murid rodent Aethomys chrysophilus: the role of geographic barriers and paleoclimate in the Zambezian bioregion." It covers loading of data, model selection, fitting and prediction as well as assessment of variable importances. Included is also the code for plotting of predicted relative occurrence rates (ROR) and for "double density plots" confronting distribution of variable values across background with its ROR-weighted version.

本数据集包含压缩后的R语言代码与必要配套数据，用于支撑《广泛分布的撒哈拉以南鼠科啮齿动物金毛非洲攀鼠（Aethomys chrysophilus）的系统地理学：赞比西生物区的地理屏障与古气候作用》一文中所采用的最大熵（MaxEnt）物种分布建模工作。该数据集覆盖数据加载、模型选择、模型拟合与预测，以及变量重要性评估全流程。此外还包含绘制预测相对发生速率（ROR）的代码，以及用于对比背景区域变量值分布与经ROR加权后的变量值分布的双密度图代码。
