Global distribution of mammalian cradles and museums is driven by past climate dynamics and present water-energy balance

<b>README</b>This repository contains a data table with all the variables used in the study to assess the drivers of phylogenetic turnover accumulation rates (CpB). Each row corresponds to an assemblage cell, and each column contains the computed variables. The columns are as follows:<b>"rich"</b>: Terrestrial mammal species richness within the assemblage.<b>"CpB"</b>: Rate of accumulation of phylogenetic turnover for all terrestrial mammals, calculated over time slices spanning millions of years (non-log-transformed).<b>"pB"</b>: Phylogenetic turnover.<b>"pBO"</b>: Phylogenetic turnover origin in millions of years.<b>"CpBpd"</b>: Rate of accumulation of phylogenetic turnover for all terrestrial mammals, calculated through slices of phylogenetic diversity.<b>"CpBchiro"</b>: Rate of accumulation of phylogenetic turnover for terrestrial mammals, excluding Chiroptera, calculated over time slices spanning millions of years.<b>"ari"</b>: Aridity index.<b>"LGM_prc"</b>: Precipitation change since the Last Glacial Maximum (LGM).<b>"LGM_tmp"</b>: Temperature change since the Last Glacial Maximum (LGM).<b>"mnt_rng"</b>: Mountain range within the assemblage cell.<b>"prc_szo"</b>: Current precipitation seasonality.<b>"tmp_szo"</b>: Current temperature seasonality.<br>

<b>数据集说明</b>本仓库收录一张数据表，其中包含本研究用于评估系统发生周转累积速率（CpB）驱动因子的全部变量。数据表中每一行对应一个集合群落单元格，每一列则代表一项计算得到的变量。各列信息如下：<b>"rich"</b>：该集合群落单元格内的陆生哺乳动物物种丰富度；<b>"CpB"</b>：基于跨百万年时间切片计算得到的全部陆生哺乳动物的系统发生周转累积速率（未进行对数转换）；<b>"pB"</b>：系统发生周转值；<b>"pBO"</b>：以百万年为单位的系统发生周转起源时间；<b>"CpBpd"</b>：基于系统发生多样性切片计算得到的全部陆生哺乳动物的系统发生周转累积速率；<b>"CpBchiro"</b>：基于跨百万年时间切片计算得到的、排除翼手目（Chiroptera）陆生哺乳动物的系统发生周转累积速率；<b>"ari"</b>：干旱指数（Aridity Index）；<b>"LGM_prc"</b>：自末次盛冰期（Last Glacial Maximum, LGM）以来的降水量变化；<b>"LGM_tmp"</b>：自末次盛冰期（LGM）以来的气温变化；<b>"mnt_rng"</b>：该集合群落单元格所在的山脉分布；<b>"prc_szo"</b>：当前降水季节性；<b>"tmp_szo"</b>：当前气温季节性。
