Synthesis and Meta-analyses workshop – providing the tools to generalize across mesocosm experiments

Partners: Lead UOL, co-lead UU, Participants: all partners

Duration: Month 15-24

Mesocosm experiments are poised to provide essential information on the response of aquatic ecosystems to current and future environmental change. At the same time, such results tend to be context-specific in the sense that the technical structure of the facility constrains treatments, sampling interval and volume, responses measured etc. In order to generalize findings across settings, methods for quantitative synthesis have been developed in the form of meta-analyses and mega-analyses, the former treating single experiments as independent studies, the latter explicitly including the non-random error structure across experiments in a single model. Partner UOL has strong expertise in both aspects and offers a two-stage workshop for AQUACOSM-plus. The first day will consist of a tutorial in research synthesis including a hands-on seminar of meta- and mega-analyses using R. The second day will allow small groups to work on research questions arising from a pre-meeting allocation of topics and identification of data. The focal group of the workshop are younger scientists developing with strong interests in conceptual ecology and data analysis.
