Data for Finkel et al. "Assessing the natural variance as a baseline for biodiversity monitoring: a case of an East Mediterranean canyon"

These are the data and R script used for the analysis presented in the manuscript "Assessing the natural variance as a baseline for biodiversity monitoring: a case of an East Mediterranean canyon" by Meir Finkel et al. These data are from Keziv Stream, Western Upper Galilee, Israel. The data are given in separate excel and csv files as follows: ants.xlsx - columns include the species names of all ant taxa found in the study, research period, and total number of individuals caught in pitfall traps in the north-facing slope (N), south-facing slope (S) and the valley bed (VB). Beetles 1998-2000.xlsx - columns include species names of four common ground beetle species caught by pitfall traps during 1998-2000, the month and year, total monthly count, mean date of all surveys conducted during this month and the number of surveys taken per month. Sampling dates are given a separate sheet. Beetles 2019-2021.xlsx - row.summary sheet summarizes beetles' the total number of individuals per research period, sampling row and collection method (pitfalls or sweeping nets), and also gives the species' global distribution pattern. raw.data details the exact collection dates and trap numbers (for pitfalls only). Eylon rain data 2018-2021.csv - rainfall data per day in 2018-2021. Dates with no rainfall are missing from the file. Note that there are two adjacent meteorological stations at the same site, one for which is manned and the other is automatic. Eylon temperature data 2018-2021.csv - temperature data per day in 2018-2022. Same two meteorological stations. NDVI.xlsx - NDVI values for August 15th to September 30th (summer minimum) from LANDSAT and MODIS (not analyzed in the paper) for 1984-2022. Columns 1 to 7 relate to the line numbers at the site. plants data.csv - Presence-absence data of plant species per line (L1 to L7) and period combination (1998-2000, indicated as 2000, vs. 2019-2021, indicated as 2020). precipitation_comb_stations_a_m.csv - homogenized rainfall data (corrected for differences in measuring devices, exact station location etc.) temperature_comb_stations.csv - homogenized temperature data (corrected for differences in measuring devices, exact station location etc.), in degrees Celsius. TN = minimum temperature. TX = maximum temperature. traps microhabitats 2019-2021.csv - The microhabitat of all pitfall traps, defined as other "open" (pitfall was not position near any plant), "shrub" (pitfall positioned near a shrub) or "tree" (pitfall positioned near a tree). SFS = south-facing slope; NFS = north-facing slope; VB = valley bed本数据集配套于Meir Finkel等人发表的论文《以自然变异作为生物多样性监测基准：东地中海峡谷案例研究》（原文标题："Assessing the natural variance as a baseline for biodiversity monitoring: a case of an East Mediterranean canyon"），包含该论文分析所用的全部数据与R脚本。本数据集的数据源自以色列上加利利西部的凯济夫溪（Keziv Stream），所有数据以独立的Excel与CSV文件形式提供，详情如下： ants.xlsx：该文件包含本研究中采集到的所有蚁类类群的物种名称、研究时段，以及北坡（N）、南坡（S）与谷底（VB）地面陷阱（pitfall trap）诱捕所得的总个体数。 Beetles 1998-2000.xlsx：该文件包含1998-2000年通过地面陷阱诱捕获得的4种常见步甲科物种的名称、采集月份与年份、月度总捕获量、当月所有调查的平均日期，以及当月的调查次数。另有单独工作表记录采样日期。 Beetles 2019-2021.xlsx：该文件包含两个工作表：①row.summary：汇总了各研究时段、采样样带与采集方式（地面陷阱或扫网）下的甲虫总个体数，同时标注了该物种的全球分布格局；②raw.data：详细记录了确切的采集日期与陷阱编号（仅针对地面陷阱）。 Eylon rain data 2018-2021.csv：该文件记录了2018-2021年的日降雨数据，无降雨的日期未纳入文件。需注意该站点设有两台相邻的气象站：一台为人工观测站，另一台为自动观测站。 Eylon temperature data 2018-2021.csv：该文件记录了2018-2022年的日气温数据，同样使用上述两台相邻的气象站观测数据。 NDVI.xlsx：该文件包含1984-2022年8月15日至9月30日（夏季植被指数最低期）的归一化植被指数（NDVI，Normalized Difference Vegetation Index）数据，数据源自LANDSAT与MODIS传感器（该数据未在论文中开展分析）。文件第1至7列对应研究样地的样带编号。 plants data.csv：该文件包含各植物物种在样带（L1至L7）与研究时段（1998-2000，标注为2000；2019-2021，标注为2020）组合下的存在-缺失数据。 precipitation_comb_stations_a_m.csv：该文件为经均一化处理的降雨数据，已校正因观测设备差异、站点精确位置不同等因素造成的系统误差。 temperature_comb_stations.csv：该文件为经均一化处理的气温数据，已校正因观测设备差异、站点精确位置不同等因素造成的系统误差，单位为摄氏度。其中TN代表最低气温，TX代表最高气温。 traps microhabitats 2019-2021.csv：该文件记录了所有地面陷阱的微生境类型，分为“开阔”（陷阱未紧邻任何植物）、“灌丛”（陷阱紧邻灌丛）与“乔木”（陷阱紧邻乔木）三类。同时标注了陷阱所在的微地形：SFS=南坡（south-facing slope），NFS=北坡（north-facing slope），VB=谷底（valley bed）。
