A method for reconstructing temporal changes in vegetation functional trait composition using Holocene pollen assemblages
Fig 5
Changes in trait community weighted means (CWMs) through time (in thousands of calendar years before present) of the Holocene pollen-derived leaf trait records from five Fenland sites (circles = Murrow; squares = Redmere; diamonds = Swineshead; point-up triangles = Welney Washes 3rd peat; point-down triangles = Welney Washes 4th peat).
Green and brown symbols indicate the predominance of herbaceous and woody taxa in the Holocene record, respectively. The means of the modern vegetation (i.e., plant-based data) are shown for herb (green vertical lines) and woody (brown vertical lines) fens. Shaded areas around the modern means depict their 95% confidence intervals. Darker-coloured symbols show Holocene samples significantly different from their equivalent (herbaceous or woody) modern vegetation means at p < 0.05 (one-observation t-tests).
