A Pilot Study on Stable Isotope Compositions of <i>Bombyx Mori</i> L. and Saturniidae Silks: Comparison of Species, Influence of Degumming Method and Tracing the Provenance of <i>Bombyx Mori</i> Silk Open
Cocoons of non-mulberry feeding silkworms from nine genera of the Saturniidae family were degummed and analyzed with regard to their 13C/12C and 15N/14N signature. The analyses reveal that the isotopic signature probably depends strongly o…

A framework for tracing timber following the Ukraine invasion Open
Scientific testing including stable isotope ratio analysis (SIRA) and trace element analysis (TEA) is critical for establishing plant origin, tackling deforestation and enforcing economic sanctions. Yet methods combining SIRA and TEA into …

A Case Study to Establish a Basis for Evaluating Geographic Origin Claims of Timber From the Solomon Islands Using Stable Isotope Ratio Analysis Open
Global demand for low-cost forest products is leading manufacturers and traders to source timber and wood products from vulnerable nations and delicate ecosystems. One small island nation, the Solomon Islands, is seeing exploitation of nat…

Using plant physiological stable oxygen isotope models to counter food fraud Open
Fraudulent food products, especially regarding false claims of geographic origin, impose economic damages of $30–$40 billion per year. Stable isotope methods, using oxygen isotopes (δ 18 O) in particular, are the leading forensic tools for…

The Development and Use of Isoscapes to Determine the Geographical Origin of Quercus spp. in the United States Open
The stable isotope ratios of oxygen, hydrogen, carbon and sulfur from extracted wood of 87 samples of oaks from the United States were analysed. Relationships with climate variables and the stable isotope ratios of the 69 training dataset …

Can isotope markers differentiate between wild and captive reptile populations? A case study based on crocodile lizards ( Shinisaurus crocodilurus ) from Vietnam Open
The international wildlife trade in allegedly “captive-bred” specimens has globally increased during recent years, while the legal origin of respective animals frequently remains doubtful. Worldwide, authorities experience strong challenge…
