Title: Phylogenetic and functional clustering illustrate the roles of adaptive radiation and dispersal filtering in jointly shaping late-Quaternary mammal assemblages on oceanic islandsJournal: Ecology LettersAuthors: Xingfeng Si, Marc W. Cadotte, T. Jonathan Davies, Alexandre Antonelli, Ping Ding, Jens-Christian Svenning, Søren Faurby Data description Island variables were obtained from Weigelt et al. (2013) and UNEP (http://islands.unep.ch), mammal occurrence data and phylogeny from the PHYLACINE 1.2 database (Faurby et al. 2018), and mammal trait data from Faurby et al. (2018), Wilman et al. (2014), and Healy et al. (2014). island.csv - Island.ID: island IDs - Latitude: the latitude of the island - Longitude: the longitude of the island - Name: the name of the island - Geology: oceanic or continental. Oceanic islands were defined as volcanic islands that emerged from the oceanic floor or continental islands that occur in the world’s oceans, and which were not connected to larger islands or nearby continental landmasses during the Last Glacial Maximum (LGM). Continental islands were defined as continental plate fragments which have been isolated during the LGM. In this study, all continental fragments (e.g., New Guinea, Borneo, Great Britain, and Hainan Island) and volcanic islands (e.g., Honshu and Kyushu Islands of Japan, Kefallinia and Ikaria Islands of Greece) that were attached to larger islands or continental landmasses during the LGM were excluded. - Area: Island area (km2) was measured as the polygon area of landmass surrounded by ocean using a cylindrical equal-area projection (Weigelt et al. 2013) - Isolation: Isolation (km) was calculated as the distance from an island’s mass centroid to the nearest mainland coast (excluding Antarctica which is covered by ice permanently) (Weigelt et al. 2013) - Temperature: maximum values per island polygon of mean annual temperature (°C). Specifically, temperature was transformed as: –1 × log10(max(x) + 1 – x), where max(x) is the maximum value of temperature (in °C) for included islands, to avoid non-positive values in log10-transformation. - Precipitation: maximum values per island polygon of mean annual precipitation (mm). Precipitation was rescaled as x/1000, where x is the original value of precipitation in millimetres mammal.occurrence.csv - Island.ID: island IDs mammal.phylo.txt - obtain from PHYLACINE 1.2 database mammal.trait.csv - Latin.name: Latin names of mammal species - Mass: body mass (grams, log10-transformed) - Diet.Plant, Diet.Vertebrate, Diet.Invertebrate: the percentage of three categories (i.e., vertebrate prey, invertebrate prey, and plants) - ForStrat.Value: Foraging stratum was coded as aerial, arboreal, ground level, or fossorial. - Activity: The timing of daily foraging activity was coded as diurnal, nocturnal, crepuscular (active at dusk and dawn), or cathemeral (active at any time of day)

数据说明：岛屿变量取自Weigelt等人（2013）及联合国环境规划署（UNEP，United Nations Environment Programme）的公开数据（http://islands.unep.ch）；哺乳动物出现数据与系统发育树取自PHYLACINE 1.2数据库（Faurby等人，2018）；哺乳动物功能性状数据取自Faurby等人（2018）、Wilman等人（2014）及Healy等人（2014）。

### island.csv 字段说明
- "Island.ID"：岛屿唯一标识符
- "Latitude"：岛屿地理纬度
- "Longitude"：岛屿地理经度
- "Name"：岛屿官方名称
- "Geology"：岛屿地质类型，分为大洋岛与大陆岛两类。大洋岛定义为源自洋壳的火山岛，或在末次冰盛期（Last Glacial Maximum，缩写LGM）未与更大岛屿或邻近大陆地块相连的海洋中大陆岛；大陆岛定义为在末次冰盛期发生隔离的大陆板块碎片。本研究排除了所有在末次冰盛期仍与更大岛屿或大陆地块相连的大陆碎片（如新几内亚、加里曼丹、大不列颠岛及海南岛）与火山岛（如日本本州岛、九州岛，希腊凯法利尼亚岛、伊卡里亚岛）。
- "Area"：岛屿面积，采用圆柱等面积投影计算的岛屿陆地块体多边形面积，单位为平方千米（km²）（Weigelt等人，2013）
- "Isolation"：岛屿隔离度，以岛屿质心到最近大陆海岸的距离计算，单位为千米（km），永久被冰盖覆盖的南极洲除外（Weigelt等人，2013）
- "Temperature"：年平均气温最大值，各岛屿多边形范围内的年平均气温最高值，单位为摄氏度（°C）。为避免对数转换出现非正值，对原始气温数据进行如下变换：–1 × log₁₀(max(x) + 1 – x)，其中max(x)为纳入研究的所有岛屿的气温最高值
- "Precipitation"：年平均降水量最大值，各岛屿多边形范围内的年平均降水量最高值，单位为毫米（mm）。对原始降水量数据进行标准化处理：将原始降水量x（单位：mm）除以1000得到标准化值

### mammal.occurrence.csv 字段说明
- "Island.ID"：岛屿唯一标识符

### mammal.phylo.txt
数据取自PHYLACINE 1.2数据库

### mammal.trait.csv 字段说明
- "Latin.name"：哺乳动物物种的拉丁学名
- "Mass"：体质量，单位为克（g），已进行log₁₀转换
- "Diet.Plant"、"Diet.Vertebrate"、"Diet.Invertebrate"：分别对应植物、脊椎动物猎物、无脊椎动物猎物三类食物的摄食百分比
- "ForStrat.Value"：觅食层位，将觅食生境分为空中、树栖、地面、地下四类
- "Activity"：活动节律，将每日觅食活动时段分为昼行性、夜行性、晨昏性（黄昏与黎明时段活跃）、全天活动性（任意时段均可活跃）四类
