Lafferty K: " The idea that some shorebirds are scum-sucking members of food webs might not have an intuitive appeal, but it does change the way that we view their ecological roles and needs. This paper does a very nice job of quantifying several aspects of this issue. I was impressed that the authors combined observations, isotope analysis, and morphological analysis to evaluate the importance of scum sucking...
