Our paper on the “progressive-change BACIPS” design was just published in MEE. This paper had a long ontogeny, starting with Laetititia’s visit to my lab to help guide her analyses of the Moorea MPA data. She and I developed the PC-BACIPS approach for those early analyses. Lauric then joined Joachim’s lab and initiated this simulation-based analysis of the PC-BACIPS approach, which evaluated how well the approach could discern different qualitative and quantitative patterns of change in studies of interventions in ecological systems. His creative insights really propelled the project. Congratulations Lauric and Laetitia!
