Data from: Can ancestry and morphology be used as surrogates for species niche relationships?

Friedrich Keppeler & Kirk Winemiller
Species interactions are difficult to quantify, and, consequently, many studies have used species traits and phylogeny as proxies under an assumption of niche conservatism (i.e., closely related and morphologically similar species should have similar niches). However, few studies have investigated whether niches actually are conserved within and across diverse communities. Here, we tested the degree to which phylogenetic relatedness and morphological similarity predict diets and stable isotopic ratios (δ15N and δ13C), two common descriptors of...
