The Interaction between Competition and Predation: A Meta-analysis of Field Experiments

Ecologists working with a range of organisms and environments have carried out manipulative field experiments that enable us to ask questions about the interaction between competition and predation (including herbivory) and about the relative strength of competition and predation in the field. Evaluated together, such a collection of studies can offer insight into the importance and function of these factors in nature. Therefore, this dataset was created by combining the results of 20 articles reporting on 39 published field experiments on the interaction between competition and predation. These experiments tested whether the presence of predators affects the intensity of competitive effects. The combined data was then analyzed using a factorial meta-analysis technique, the results of which were published in the study titled The Interaction between Competition and Predation: A Meta‐analysis of Field Experiments (Gurevitch et al., 2000).从事各类生物与环境研究的生态学者通过开展操控性野外实验，得以围绕竞争与捕食（包括植食作用）的相互作用，以及野外环境中竞争与捕食的相对强度提出相关科学问题。若对这类研究集合进行整合评估，则可揭示上述两类生态因子在自然生态系统中的重要性与作用机制。因此，本数据集通过整合20篇文献的研究结果构建而成，这些文献共报道了39项已发表的、针对竞争与捕食相互作用的野外实验。这些实验旨在检验捕食者的存在是否会改变竞争效应的强度。随后，研究人员采用析因元分析（factorial meta-analysis）方法对整合后的数据进行分析，相关分析结果发表于题为《竞争与捕食的相互作用：野外实验的元分析》（The Interaction between Competition and Predation: A Meta‐analysis of Field Experiments, Gurevitch等，2000）的研究中。
