  abstract = {{W}e explored the use of stable nitrogen ({N}) isotope analysis to assess trophic position of consumers in two marine ecosystems: the kelp forests of southern {C}alifornia and a coral atoll in the tropical {P}acific. {T}he delta {N}-15 values of consumers in both ecosystems increased from known herbivores (invertebrates and fish) to higher-level consumers (predatory invertebrates and fish). {I}n the absence of data on trophic enrichment in {N}-15 for our study species, we used the oft-cited value of +3.4 parts per thousand increase in delta {N}-15 value per trophic level and estimates of the delta {N}-15 producer baseline value to estimate trophic position. {T}he trophic position of consumers computed using {N} isotopes compared favorably to published observations of diet. {N}itrogen isotope analysis revealed that some of our higher-level fish consumers from rocky reefs (i.e., some rockfish) were feeding largely on invertebrates rather than on fish, as is often assumed. {O}ur analysis also suggests that higher-level consumers on coral reefs may consume more herbivorous prey (i.e., both fishes and invertebrates) than previously reported. {O}ur data support the use of nitrogen isotope values to assess trophic position and, thus, their utility as one metric with which to explore the effects of short- and longer-term natural and human-induced changes on kelp forest and coral reef food webs.},
