Background: Iron deficiency is common in obese subjects. This may be due to an increase in serum hepcidin and a decrease in iron absorption from adiposity-related inflammation.
We used water d2H and d18O from ca. 1000 lakes sampled in the 2007 U.S. Environmental Protection Agency’s National Lakes Assessment (NLA) to assess two hydrological variables—evaporation as a percent...
We used d15N-nitrate (NO{ 3 ) and d18O-NO{ 3 to unravel the provenance and fate of NO{ 3 in a groundwater-fed estuary. A total of 13 monthly and two time series surveys were undertaken in the Werr...
Characteristics of δ2 H and δ18O in precipitation samples collected at 16- to 17-d intervals at three stations at the northern end of Honshu Island, Japan, were investigated. Rokkasho and Ajigasawa ...
Benthic marine consumers inhabiting the subphotic zone rely on subsidies of energy synthesized by macrophytes and phytoplankton in the photic zone. The effects of this energy subsidy on the trophic ec...
Understanding the source and chemical characteristics of groundwater used for sake production is an important strategy for the quality management of sake brewing. Oxygen isotope ratios (δ18O) of 96 s...
The Namseong gold and silver deposit is located in the Seolcheon metallogenic province, one of the most important gold production areas in the Republic of Korea. It consists of three gold and silver-...
We used amino acid (AA) compound-specific isotope analysis (d15NAA and d13 CAA values) of midwater zooplankton and suspended particles to examine their dynamics in the mesopelagic zone. Suspended pa...
Bayesian Stable Isotope Mixing Models     Bayesian  Stable  Isotope  Mixing  Models       2012/11/23
In this paper we review recent advances in Stable Isotope Mixing Models (SIMMs) and place them into an over-arching Bayesian statistical framework which allows for several useful extensions. SIMMs are...
To determine the accuracy and precision limits associated with carbon stable isotope ratio (δ13C) measurements of cellulose and lignin from plant samples, experiments were performed using differing e...
Estuarine fish may remain as residents in areas with favorable conditions for feeding and refuge, but become mobile and transient where conditions are less favorable. We developed a new approach invol...
We measuredd13CofCO2,CH4, and acetate-methyl in profundal sediment of eutrophic Lake Dagow by incubation experiments in the presence and absence of methanogenic inhibitors chloroform, bromoethane sulf...
A pattern of succession has been demonstrated at Gulf of Mexico cold seeps proceeding from a high-biomass endemic community dominated by grazers to a diverse community of endemic and nonendemic speci...
Constructed wetlands attenuate effluent nutrients, are hydrodynamically well defined, and are a useful proxy for the study of nitrogen (N) transformation in eutrophic natural systems. A whole-system s...
We compared stable nitrogen isotope (d15N) values from the common Caribbean sea fanGorgonia ventalina,collected from a developed and undeveloped coastline, to test the hypothesis that sewage-derived n...
