Abstract | Plants communicate information about their status, intra- and inter- plant, and with other ecosystem members, through the release of volatile organic compounds (VOCs). The effects of rising CO2 in conjunction with ozone (O3) on plant VOC emissions is not yet fully understood, but research suggests that some herbivore-induced VOCs are degraded by O3, potentially reducing their signalling function. Furthermore, elevated CO2 has been shown to attenuate induced VOC responses to herbivory in Brassica oleracea. We are using two tri-trophic model systems; black poplar [Populus nigra betulifolia], winter moth [Operophtera brumata] and a tachinid fly parasitoid of winter moth, Cyzenis albicans; and oil seed rape [Brassica napus], diamond back moth [Plutella xylostella] (DBM), and a parasitoid of DBM, braconid wasp, Cotesia plutella. Additionally, we are working within two ground-breaking facilities; the Birmingham Institute of Forest Research (BIFoR)’s free-air carbon enrichment (FACE) experiment, and University of Reading’s free-air diesel and ozone enrichment experiment. We will also collect some data from lab-based experiments. Our project seeks to characterise the volatile organic compound (VOC) profiles emitted for both plants under herbivory, examine how these VOC profiles differ under combined elevated CO2 and O3, and explore whether changes to VOC profiles impact key ecological relationships, e.g, the ability of plants to signal to herbivore enemies. |
