IRMS #: 0015 PI: Amy Hirons (NMNH) Smithsonian Initiative: Understanding and Sustaining a Biodiverse Planet Title: Examination of trophic structure of the Northwest Hawaiian Islands throughout the 20 th century: evidence from the stable isotope signatures of monk seals Project Summary: This study looks at the trophic structure of the Northwest Hawaiian Islands throughout predominantly the 20th century in an effort to better understand this species and develop appropriate conservation methods. This study includes monk seal bone collagen as well as vertebrate and invertebrate prey items of these seals which will be used to establish a food web through carbon and nitrogen stable isotope analyses. IRMS #: 0016 PI: Amy Hirons (NMNH) Smithsonian Initiative: Understanding and Sustaining a Biodiverse Planet Title: Stable isotope signatures of sea otter vibrissae as evidence for temporal/spatial distribution Project Summary: This study consists of the analysis of sea otter vibrissae. The animals' temporal/spatial distribution will be correlated to the δ 13 C and δ 15 N values. IRMS #: 0017 PI: Amy Hirons (NMNH) Smithsonian Initiative: Understanding and Sustaining a Biodiverse Planet Title: Temporal and spatial distribution of sea otters in the Bering Sea and North pacific: evidence from stable isotopes Project Summary: This study consists of analyses of Steller sea lion vibrissae for carbon and nitrogen stable isotopes. This is a continuation of our long-term temporal sea lion trophic studies, focused on the western side of the Bering Sea and North Pacific. IRMS #: 0018 PI: Amy Hirons (NMNH) Smithsonian Initiative: Understanding and Sustaining a Biodiverse Planet Title: Tracking a turtle’s ocean journey using stable isotope signatures Project Summary: Many species of sea turtles are known to be highly migratory throughout their lifespan. Understanding these migration patterns is crucial for conservation efforts. This project will analyze the stable carbon and nitrogen isotopic signature of several species of sea turtle scute (shell), egg case and bone collagen. This preliminary project will determine if the turtles' ocean journey can be tracked with stable isotopes. 30
IRMS #: 0019 PI: Amy Hirons (NMNH) Smithsonian Initiative: Understanding and Sustaining a Biodiverse Planet Title: Stable isotopic indications of seagrass contribution to diet and habitat Project Summary: This project examines seagrass contribution to diet and as habitat. A variety of organisms such as algae, invertebrates and vertebrate muscle will be examined isotopically for their relationship to the seagrass. Additionally, seasonal variability in the seagrass influence will be examined. IRMS #: 0020 PI: Christine France (MCI) Smithsonian Initiative: Understanding and Sustaining a Biodiverse Planet Title: Thermoregulatory adaptations of Acrocanthosaurus atokensis – evidence from oxygen isotopes Project Summary: The thermoregulatory strategy of Acrocanthosaurus atokensis is currently unknown. This study aims to discern the internal temperature patterns of this large theropod dinosaur and determine if it was a homeotherm or a heterotherm. Oxygen isotopes, which are sensitive to variations in body temperature, will be compared across different bones of the same individual. The overall interbone temperature pattern as indicated by the δ 18 O values will be compared to the pattern from an ostrich (a known homeotherm and direct descendant of the dinosaur lineage), an elephant (a known large homeotherm), and an alligator (a known large heterotherm). IRMS #: 0021 PIs: Peter Marra (NZP) and Carla Dove (NMNH) Smithsonian Initiative: Understanding and Sustaining a Biodiverse Planet Title: Investigation of the migratory nature of Canadian geese causing the crash of US Airways Flight 1549 Project Summary: In January 2009, multiple engine strikes from Canadian geese forced the crash-landing of US Airways Flight 1549 in the Hudson River. Hydrogen isotopic data for the feather remains of the birds were compared to both migratory and local populations of geese in an effort to determine which of these groups was most similar isotopically to the bird remains. Determination of the migratory status of the birds responsible for the crash is critical to future preventative measures. 31
