Welch, Andreanna J.; Wiley, Anne E.; James, Helen F.; Ostrom, Peggy H.; Stafford, Thomas W.; Fleischer, Robert C. (2012)In the Hawaiian Islands human colonization, which began approximately 1200 to 800 years ago, marks the beginning of a period in which nearly 75% of the endemic avifauna became extinct and the population size and range of ...

Morra, Kaycee E.; Wiley, Anne E.; James, Helen F.; Dutcher, Alex; Ostrom, Peggy H. (2018)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 ...

Wiley, Anne E.; Ostrom, Peggy H.; Stricker, Craig A.; James, Helen F.; Gandhi, Hasand (2010)We wish to use stable-isotope analysis of flight feathers to understand the feeding behavior of pelagic seabirds, such as the Hawaiian Petrel (Pterodroma sandwichensis) and Newell's Shearwater (Puffinus auricularis ...

Wiley, Anne E.; Ostrom, Peggy H.; Welch, Andreanna J.; Fleischer, Robert C.; Gandhi, Hasand; Southon, John R.; Stafford, Thomas W.; Penniman, Jay F.; Hu, Darcy; Duvall, Fern P.; James, Helen F. (2013)Human exploitation of marine ecosystems is more recent in oceanic than near shore regions, yet our understanding of human impacts on oceanic food webs is comparatively poor. Few records of species that live beyond the ...

Morra, Kaycee E.; Chikaraishi, Yoshito; James, Helen F.; Rossman, Sam; Wiley, Anne E.; Ostrom, Peggy H. (2020)Stable isotope analyses of archival specimens have revealed trophic declines over the past 150 yr in a growing number of predatory pelagic seabirds that breed in the Hawaiian Islands. However, they have not examined whether ...

Morra, Kaycee E.; Chikaraishi, Yoshito; Gandhi, Hasand; James, Helen F.; Rossman, Sam; Wiley, Anne E.; Raine, Andre F.; Beck, Jessie; Ostrom, Peggy H. (2019)We investigated how foraging habits vary among three ecologically distinct wide-ranging seabirds. Using amino acid N-15 proxies for nutrient regime (N-15(Phe)) and trophic position (N-15(Glu-Phe)), we compared Newell's ...

Ostrom, Peggy H.; Wiley, Anne E.; Rossman, Sam; Stricker, Craig A.; James, Helen F. (2014)Hydrogen isotopes have significantly enhanced our understanding of the biogeography of migratory animals. The basis for this methodology lies in predictable, continental patterns of precipitation dD values that are often ...
