Griffen et al. (2016) proposed that studies should be designed:
- to lead to a mechanistic understanding of the observed responses (rather than just description);
- to parameterize and inform population and ecosystem models, in order to allow upscaling from the experiments to field populations, communities and ecosystems;
- with a sufficient number of levels of the driver(s) to inform about the presence of linear or non-linear responses including thresholds to the drivers;
- conclusions about effect sizes and interactions (additive or multiplicative) need to consider the data model used, as data transformation changes the statistical model being tested.
