Emeritus Professor

Faculty:Faculty of Science & Technology

Location: Cambridge

Areas of Expertise: Life sciences

John taught organic chemistry at Anglia Ruskin from 1981 to retirement in 2007 and was Director of the former Environmental Sciences Research Centre. He currently helps in supervising research students.

Background

John maintains his research interests in the use of stable isotopes in tree rings for environmental reconstruction, and chemical communication in mammals.

Research interests

  • Isotopic dendroclimatology concerns the measurement of the ratios of the stable isotopes of carbon, oxygen and hydrogen in the cellulose of tree rings. The precise values of these ratios depends upon the climatic conditions under which the tree ring was laid down, and so tree rings can provide a record of past climate in their record of isotope ratios. The great advantage of tree rings over other proxy climate records lies in the unambiguous annual resolution that the rings provide. The isotope ratios in living trees have also provided evidence for the ways in which trees are responding to the present increases in the level of atmospheric carbon dioxide. Work has been carried out at an international level with several institutions across the UK and Europe. Funding for projects has been obtained from NERC, the Leverhulme Trust and the European Commission.
  • Mammalian semiochemistry refers to the study of chemical communication between mammals. Social interaction is often mediated by olfactory communication, which can provide information on matters such as social and sexual status, emotional state, and territoriality. The organic compounds necessary for this communication are usually volatile, so that they can be detected at a distance. Urine, faeces and glandular secretions are all used to transmit chemical information. Knowledge of olfactory communication can be a great help in understanding animal behaviour, and may be used to develop environmentally acceptable methods of control and in the conservation of endangered species.
