Project description
Bud burst and leaf development in forests are fine-tuned to climate and use a suite of environmental cues to coordinate development between the canopy and understorey and with the biodiversity dependent on the forest. This in turn feeds back to the nutrient cycles and water use. Changing day length and light quality (UV:visible radiation, red:far-red, blue:green) help control phenology, allowing plants to optimise resource use. I will monitor the full solar spectrum in forests of differing composition and growing along a latitudinal gradient. I will use these data on changing spectral quality to examine the response of plants to selected candidate signals in field and greenhouse experiments. The results will allow expectations of changes in species range and ecosystem function under climate change to be tested. Data on phenology and spectral composition will be used to model forest water use and carbon budgets.
