Description

SUPPLEMENTARY DATA FOR: Jolles, Briggs, Araya-Ajoy, & Boogert (2019) Personality, plasticity and predictability in sticklebacks: bold fish are less plastic and more predictable than shy fish. SUMMARY: In this study we tested 80 individual wild-caught three-spined sticklebacks (Gasterosteus aculeatus) repeatedly over a 10-week period in a classic boldness assay to investigate the links between the personality, plasticity and predictability. Fish were tested in random order in one of eight replicate testing boxes under controlled laboratory conditions. Using a mixed-modelling approach we demonstrate that individual variation in boldness, i.e. the tendency to trade off risks versus potential rewards, is fundamentally linked to temporal plasticity and predictability: bold fish were less plastic in their behaviour and more predictable than shy fish. Statistical simulations using a novel statistical framework (‘SQUiD’) show that our experimental dataset has sufficient statistical power to provide accurate and precise statistical parameter estimates. DATA: All raw data of the boldness trials is provided in the file boldnessdat.csv and the code for running the final mixed model of the experimental dataset before the testing break and subsequently setting up and running statistical simulations using the SQuID framework cna be found in the file squidsimulations.r. id = identity of the fish. testwk = week of testing relative to start of experimental period. session = sequence number of testing trial for that individual over the testing period. trial = sequence number of testing trial during the day. box = testing box in which the fish was tested. prop.out = the proportion of time a fish spent out of cover in the boldness assay. id.group = identity of the group a fish was housed in over the testing break between weeks 6 and 10.
