Stable Isotope Ratios and Forensic Analysis of Microorganisms [PDF]
Applied and Environmental Microbiology, 2007 ABSTRACTIn the aftermath of the anthrax letters of 2001, researchers have been exploring various analytical signatures for the purpose of characterizing the production environment of microorganisms. One such signature is stable isotope ratios, which in heterotrophs, are a function of nutrient and water sources. Here we discuss the use of stable isotope

Equations for lipid normalization of carbon stable isotope ratios in aquatic bird eggs. [PDF]
PLoS ONE, 2014 Stable isotope ratios are biogeochemical tracers that can be used to determine the source of nutrients and contaminants in avian eggs. However, the interpretation of stable carbon ratios in lipid-rich eggs is complicated because (13)C is depleted in ...
