Fig. S5. Hourly atmospheric temperature and hourly maximum photosynthetically active radiation (PARmax) records collected since October 2012 at a weather station on Calvert Island. Black line shows the seasonal trends, and color of data points represent anomalies from the seasonal trend. The weather station is located above Foggy Cove at 63m above sea-level at the top of a nearby hill that is often above the fog layer
Selection of taxa: Because we were interested in modelling species abundance as a function of year, we could only include species that occurred fairly regularly. The rarest taxa were not included in the joint species distribution modeling with HMSC. We could have included those species, but we would have had far less certainty about distributional patterns in any one year, as well as patterns across years. Therefore, we set an arbitrary threshold that species must have occurred in at least 48 plots throughout the entire time series, which equates to an average of 6 quadrats per year. This threshold left a minimum of XX observations in any year and a minimum of XX percent cover in any year.
