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

Scientific Reports, 2022 Alteration of conventional carbonate stable isotopes (δ18O, δ13C) in cave walls has been shown to be a useful tool to identify cave formation driven by deep-seated processes, i.e., hypogene karstification.

Empirical food webs of 12 tropical reservoirs in Singapore [PDF]
Biodiversity Data Journal, 2022 Food webs summarise trophic interactions of the biotic components within an ecosystem, which can influence nutrient dynamics and energy flows, ultimately affecting ecosystem functions and services.

Stable Isotope Approaches in Vadose Zone Research
Vadose Zone Journal, 2018 Recent developments in the measurement, modeling, and application of stable isotope tools to provide insights on water flow, transport, biogeochemical, and ecological processes in the vadose zone have motivated a special section in .

Stable Isotope Analysis of Greenhouse Gases Requires Analyte Preconcentration
CHIMIA, 2022 Nitrous oxide (N2O) is an important trace gas contributing to global warming and depletion of ozone in the stratosphere. Its increasing abundance is caused mainly by anthropogenic sources, such as application of fertilizers in agriculture or emissions ...

Stable Isotope Studies of North American Arctic Populations: A Review
Open Quaternary, 2019 We review the major stable carbon and nitrogen isotope studies conducted on human remains in the North American Arctic (NAA) and discuss the findings with respect to two major research themes: diachronic subsistence, and the development of food cultures ...
