Dataset Artificial warming decreases heterotroph densities and predator-prey biomass ratio in aquatic systems

This file holds the data and scripts used in the article "Artificial warming decreases heterotroph densities and predator-prey biomass ratio in aquatic systems".Data are available in files whose name begins with the prefix "df". The variables names "date" and "date_c" represent the sampling date in discrete or continue value, respectively. "mesocosm_ID" is the identity of the mesocosm. "fish" represent the fish treatment (NF for No Fish, LB for Large-bodied fish and SB for Small-bodied fish). "warming" is the temperature treatment (NW for no warming, W for warming). "tmean15" is the mean temperature of the 15 days prior to the sampling date. "compartment", "class", "order" and "taxa" represent the taxonomy of the organisms. "N_l" is the density per liter. "C_mug_l" is the carbon biomass in microgram per liter. "S" and "H" are the species richness and the Shannon diversity index, respectively. "ZP" is the zooplankton:phytoplankton biomass ratio. The variables in df_bss.csv file are described in the main text of the article.Files with a numerical prefix are the scripts used for the statistical analyzes (multivariate analyzes, ecological index, community density and biomass, Predator Prey Biomass Ratio and Biomass Size Spectra).

本文件收录了论文《人工增温降低水生系统中异养生物密度与捕食者-猎物生物量比》所使用的实验数据与分析脚本。实验数据存储于文件名前缀为"df"的文件中。变量"date"与"date_c"分别对应离散形式与连续形式的采样日期。"mesocosm_ID"为中型实验生态系统（mesocosm）的唯一标识。"fish"代表鱼类处理组别：NF为无鱼组（No Fish）、LB为大型鱼类组（Large-bodied fish）、SB为小型鱼类组（Small-bodied fish）。"warming"代表温度处理组别：NW为无增温组（no warming）、W为增温组（warming）。"tmean15"为采样日期前15天的平均温度。"compartment"、"class"、"order"与"taxa"分别对应生物的分类层级：生境分区、纲、目与类群。"N_l"为每升水体的生物个体密度。"C_mug_l"为每升水体的碳生物量，单位为微克。"S"与"H"分别代表物种丰富度与香农多样性指数。"ZP"为浮游动物与浮游植物的生物量比值。df_bss.csv文件中的变量详见论文正文。带有数字前缀的文件为统计分析所用脚本，涵盖多元分析、生态指数计算、群落密度与生物量分析、捕食者-猎物生物量比分析以及生物量粒径谱分析。
