Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial ana ....Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods. Expected outcomes are a mechanistic understanding of tree-mediated methane fluxes, helping to constrain regional, national and global methane budgets. The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.Read moreRead less
Brains frozen in time: vertebrate neural adaptations to invading land . The evolution of terrestrial animals from fish was one of the most significant events in our evolution, yet little is known about how the brain evolved during this transition. This project aims to investigate the major novelties acquired in the evolution of the early vertebrate brain in order to determine the functional reasons for such changes, as well as identifying the timing and environmental factors driving such changes ....Brains frozen in time: vertebrate neural adaptations to invading land .
