Probability distributions of mean carbon range (CR) for different food chain lengths within each food chain.

<p>Distributions based on resampling (<i>n</i> = 10,000) of uncertainty in sample mean estimates. 50%, 75% and 95% credible intervals as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0093281#pone-0093281-g002" target="_blank">Fig. 2</a>. x-axis: p = plant, a = aphid, h = hoverfly, w = wasp. Numbers in parenthesis show food chain length.
