资源简介:

These consumer functional response datasets were extracted from the literature, either from tables or from figures. While some entail "raw" data, most represent means and associated levels of uncertainty (expressed as standard errors). Two types of functional response experiments are represented:1) experiments entailing 1 consumer species and 1 prey/host species in which both prey/host and consumer abundances are varied;2) experiments entailing 1 consumer species and 2 prey/host species in which both prey/host abundances are varied.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~The structure of the data varies somewhat across datasets, but in general..Preds (or Parasitoids) - number of predator (parasitoid) individualsPrey (or Hosts) - number of prey (host) individualsEaten (or Parasitized) - number of prey (hosts) eaten (parasitized)Time - the time-period of the experiment (not standardized)For datasets represented by summary statistics...Prey.Eaten.Mean - arithmetic mean number of prey eatenPrey.Eaten.SE - standard error of the mean number of prey eatenn - treatment sample size (number of replicates)For datasets entailing two prey/host species, the numbers available and eaten are indicated by Prey1 and Prey2.

本消费者功能响应数据集均提取自已发表文献,来源涵盖文献表格与插图。尽管部分数据集包含原始数据,但绝大多数仅呈现均值及其对应的不确定度水平(以标准误表示)。本数据集涵盖两类功能响应实验:1)单消费者物种-单猎物/寄主物种实验,即同时改变猎物/寄主与消费者的种群丰度;2)单消费者物种-双猎物/寄主物种实验,即同时改变两种猎物/寄主的种群丰度。 各数据集的数据结构存在一定差异,但总体而言: 捕食者(Preds)或寄生性天敌(Parasitoids)个体数:对应捕食者或寄生性天敌的个体总量 猎物(Prey)或寄主(Hosts)个体数:对应猎物或寄主的个体总量 被捕食个体数(Eaten)或被寄生个体数(Parasitized):对应被捕食或被寄生的猎物/寄主个体数量 实验时长(Time):实验的时间周期(未进行标准化处理) 对于以汇总统计量呈现的数据集: 猎物被捕食均值(Prey.Eaten.Mean):被捕食猎物数量的算术平均值 猎物被捕食标准误(Prey.Eaten.SE):被捕食猎物数量均值的标准误 样本量(n):处理组的重复样本数 对于包含双猎物/寄主物种的数据集,可用猎物(寄主)与被捕食(被寄生)猎物(寄主)的数量分别以Prey1和Prey2标注。
