Fungal mat growth and leaf colonization at the TRACE warming experiment, Mar - Aug 2024, Luquillo, Puerto Rico

This data package contains processed measurements on the growth of litter mat-forming fungi and the time to leaf colonization at the Tropical Responses to Altered Climate Experiment (TRACE). Located near the Sabana Field Research Station in Luquillo, Puerto Rico, the TRACE site is located in a mature, closed-canopy tropical rainforest within the Luquillo Experimental Forest (LEF). These data quantify fungal mat growth and the time to leaf colonization of fungi species Gymnopus johnstonii and Marasmius crinis-equi. The experiment was conducted in ambient (control) and experimentally warmed plots (4°C above ambient) during spring and summer periods to assess how litter mat-forming fungi respond to a range of environmental conditions of tropical wet forests. The data files include tables of relative fungal mat growth rates, time to leaf colonization, averages of soil temperature (°C), and number of dry days before leaf attachment. The data are stored in comma-separated values (CSV) format and viewable with any text editor, spreadsheet, or statistical software (e.g., R, Python, Excel). Associated metadata describe plot identifiers, measurement descriptions, and processing steps.

本数据集包含来自热带气候改变响应实验（Tropical Responses to Altered Climate Experiment, TRACE）的预处理测量数据，内容涉及凋落物垫形成真菌的生长情况与叶片定殖时长。该实验站点位于波多黎各卢基约的萨瓦纳野外研究站附近，地处卢基约实验林（Luquillo Experimental Forest, LEF）内的成熟封闭冠层热带雨林中。本数据集量化了真菌物种约氏裸柄伞（Gymnopus johnstonii）与马勃状小皮伞（Marasmius crinis-equi）的真菌垫生长情况及叶片定殖时长。本实验于春季和夏季开展，设置了环境对照样地与人工增温样地（较环境温度高4℃），以探究凋落物垫形成真菌对热带湿润森林多种环境条件的响应模式。数据文件包含相对真菌垫生长速率、叶片定殖时长、土壤平均温度（单位：℃）以及叶片附着前干旱天数的统计表。数据以逗号分隔值（Comma-Separated Values, CSV）格式存储，可通过任意文本编辑器、电子表格或统计软件（如R、Python、Excel）打开查看。配套元数据包含样地标识符、测量项说明与数据处理流程等内容。
