TL;DR: Organizational structure for the proposed IsoBank would oversee four subcommittees (SC): Information technology, integrative disciplinary, education and training, and analytical expertise.
Journal ArticleDOI
Temporal trends of mercury in marine biota of west and northwest Greenland
TL;DR: Temporal trends in mercury concentrations ([Hg]) during the last two to three decades were determined in liver of shorthorn sculpin, ringed seal and Atlantic walrus from northwest Greenland (NWG, 77 degrees N) and in liver from central west Greenland (CWG), and including tissue delta(15)N values as a covariate had a marked effect on results.
Journal ArticleDOI
Using Stable Hydrogen Isotope Analysis of Feathers to Delineate Origins of Harvested Sandhill Cranes in the Central Flyway of North America
Keith A. Hobson,Steven L. Van Wilgenburg,Leonard I. Wassenaar,Helen Hands,William P. Johnson,Mike O'Meilia,Philip Taylor +6 more
TL;DR: This paper used stable-hydrogen isotope analyses (δD) of feathers from 242 hatch-year (HY) and 628 after-hatch year (AHY) cranes harvested during the 2002 and 2003 hunting seasons in Saskatchewan, North Dakota, Kansas, Oklahoma, and Texas in order to provide new quantitative information regarding their geographical origins.
Journal ArticleDOI
Using hydrogen isotopes to assign origins of bats in the eastern united states
TL;DR: Stable hydrogen isotopes in metabolically inert tissues such as feathers and hair provide a set of endogenous markers that may be useful for establishing migratory connectivity in animals, but significant intra- and interspecific variation in δDh values suggests that pooling across sex and age categories and use of surrogate species should be avoided.
Journal ArticleDOI
Long-distance autumn migration across the Sahara by painted lady butterflies: exploiting resource pulses in the tropical savannah.
Constantino Stefanescu,David X. Soto,Gerard Talavera,Gerard Talavera,Roger Vila,Keith A. Hobson,Keith A. Hobson +6 more
TL;DR: The isotopic composition of butterflies from seven European and seven African countries is analysed to provide new support for the hypothesis that autumn movements are not only directed to northwestern Africa, but also include southward and northward flights across the Sahara.
