Carbon stable isotope analysis of cereal remains as a way to reconstruct water availability: preliminary results [PDF]

, 2011
Reconstructing past water availability, both as rainfall and irrigation, is important to answer questions about the way society reacts to climate and its changes and the role of irrigation in the development of social complexity.

Stable-isotope Labeled Metabolic Analysis in Drosophila melanogaster: From Experimental Setup to Data Analysis

Bio-Protocol, 2018
Stable-isotope labeled metabolic analysis is an essential methodology to characterize metabolic regulation during biological processes. However, the method using stable-isotope-labeled tracer (e.g., 13C-glucose) in live animal is only beginning to be ...

Combined stable isotope and gut contents analysis of food webs in plant-dominated, shallow lakes [PDF]

, 2003
1. To determine feeding links between primary producers, invertebrates and fish, stable isotope analyses and gut content analyses of fish were conducted on the components of four shallow, eutrophic to hypertrophic, plant-dominated lakes. 2.
