In a frustrating development, my co-author Nigel Hussey reported problems from other researchers in replicating our trophic position calculations from our recent Ecology Letters paper. In it, trophic position is, regrettably (and completely my fault) missing a +TPbase (trophic position of the baseline organism) at the end. The correct equation is:
My apologies to Nigel and my co-authors for not catching this in the proofs.
