Insect food preferences analysed using 13C/12C ratios

  title={Insect food preferences analysed using 13C/12C ratios},
  author={Michael Petelle and Bruce Haines and Evelyn Haines},
Stable carbon isotope ratio analysis is a powerful technique in tracing ecosystem carbon flows, especially those between primary and secondary producers. The distinctive 13C/12C ratios of plant species tend to pass along the food chain with little further fractionation, hence the stable carbon isotope composition of an animal is an important clue to what it has eaten. We compared the stable carbon isotope composition of plants and insects in an old field in Georgia. Of the dominant plants in… CONTINUE READING
