From: Reconstructing predation intensity on crinoids using longitudinal and cross-sectional approaches
Estimates of average predation intensity (± 1 standard error) for two feather stars, Capillaster multiradiatus (solid symbols) and Clarkcomanthus mirabilis (open symbols) obtained using two independent approaches. Predation intensities, icross, plotted on the x-axis were obtained using Eq. 1 (circles) and Eq. 2 (squares), whereas ilong on the y-axis were obtained using longitudinal data only. The dotted, diagonal line has a slope of 1, thus for points falling on the line ilong = icross. The secondary x-axis (top) represents the average waiting time between injuries calculated as 1/i; a corresponding secondary y-axis is not labeled to avoid clutter
