Quantifying individual specialization and other forms of intraspecific ecological diversity can reveal variation that is critical for evolutionary or behavioral adaption of a species to changing environments. Here, the isotopic niche and degree of individual foraging specialization were quantified for an endangered seabird, the Hawaiian petrel (Pterodroma sandwichensis), nesting on Lānaʻi (20°48′N, 156°52′W) and 72 km away on Haleakalā, Maui (20°42′N, 156°15′W; 20° 43′N, 156°14′W) between 2006 a...

We investigated how foraging habits vary among three ecologically distinct wide-ranging seabirds. Using amino acid δ15N proxies for nutrient regime (δ15NPhe) and trophic position (Δδ15NGlu-Phe), we compared Newell’s shearwater (Puffinus newelli) and Laysan albatross (Phoebastria immutabilis) foraging habits over the past 50–100 years, respectively, to published records for the Hawaiian petrel (Pterodroma sandwichensis). Standard ellipses constructed from the isotope proxies show that inter-popul...

Carotenoid-based ornaments are common signalling features in animals. It has long been proposed that such ornaments communicate information about foraging abilities to potential mates. However, evi...

Abstract. Isotope data from Hawaiian Petrel (Pterodroma sandwichensis) primaries P1 and P6 were compared to determine whether foraging habits change between the beginning and middle of the nonbreeding season. P6 data did not differ between samples derived from a longitudinal and a minimally invasive protocol and point samples taken from the feather bases. While P6 δ13C increased longitudinally, no δ15N longitudinal trends emerged, yet inter-individual δ15N variability was high. P6 δ13C data sugg...

Human-induced ecological change in the open oceans appears to be accelerating. Fisheries, climate change and elevated nutrient inputs are variously blamed, at least in part, for altering oceanic ec...
