“I am an isotope ecologist with interests in developing new stable isotope methods and techniques for tracing spatio-temporal changes in food webs, and understanding animal movement and large-scale migration. My current research focus is on aquatic food webs using isotopic tracers such as hydrogen isotopes, and on insect migration patterns predicting natal origins by combining isoscapes and likelihood-based geospatial assignment methods.”
Animals feeding at sea inherit a chemical record reflecting the area where they fed, which can help track their movements, according to a new study by scientists from the University of Southampton.
Chemical testing of the source of marine food products could be a powerful tool to help to fight food fraud, maintain healthy sustainable fish stocks or marine protected areas, and ensure consumer confidence in marine eco-labelling. Continue reading →
Isotopes are atoms that have the same number of protons and electrons but differ in their number of neutrons; they are lighter and heavier forms of the same element. Unlike radioactive isotopes, stable isotopes do not decay over time.
