What determines plant sensitivity to heat?: Individual to lifetime impacts. Temperature is a major determinant of the distribution of species and yet the capacity to predict the thermal sensitivity of plants is extremely limited. How vulnerability varies as a plant grows from seed to adult and produces more seed is a key question. Whether chronic warming exacerbates or ameliorates effects of extreme events, e.g. triggering the plant to enlist defensive strategies, is also an open question.

Temperature is a major determinant of the distribution of species and yet the capacity to predict the thermal sensitivity of plants is extremely limited. How vulnerability varies as a plant grows from seed to adult and produces more seed is a key question. Whether chronic warming exacerbates or ameliorates effects of extreme events, e.g. triggering the plant to enlist defensive strategies, is also an open question. This project will advance fundamental understanding of how thermal tolerance varies across species and over the plant life cycle and how it scales demographically to lifetime vulnerability. The work will yield a significant advance in our capacity to predict impacts of extreme heat events on plant performance and distribution.

Improving long term forecasts of tree growth in carbon farming projects. Australia is taking action to limit global warming, including use of "carbon farming" to capture CO2 using trees as natural carbon sinks. Limited knowledge on the growth rate of Mulga trees, a primary carbon sink, hampers our partner organisation’s ability to maximise carbon stores.

Australia is taking action to limit global warming, including use of "carbon farming" to capture CO2 using trees as natural carbon sinks. Limited knowledge on the growth rate of Mulga trees, a primary carbon sink, hampers our partner organisation’s ability to maximise carbon stores. The aim of this proposal is to use dendrochronology to inform novel predictive models for growth of mulga trees that will reduce uncertainty in carbon removal forecasts. The expected outcome will be significant and benefit our partner organisation and other agencies by providing improved forecasting of tree growth that will inform their decisions for investment in carbon farming and nature repair markets.Read moreRead less
Sex is important in adaptation to environmental change. Aims: This project will use novel experiments with the aim of determining the potential for plasticity to be adaptive with sexual selection and how non-genetic effects transfer across generations by establishing genomic mechanisms. Significance: Plasticity (or acclimation) is often hailed as the saviour for species in the face of rapid climate change, but it is problematic if it is not adaptive in nature. Expected outcomes: Expected outcome ....Sex is important in adaptation to environmental change.

The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.Read moreRead less

This project aims to uncover the role low oxygen plays in shaping healthy corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs, yet we have no knowledge of how less oxygen availability affects critical life history factors that govern coral resilience: growth, reproduction, and stress tolerance. This project unites a multidisciplinary team of experts to, for the first time, couple advanced oxygen sensing, metabolic physiology, coral reproductive and stress biology to transform our understanding of oxygen thresholds that are diagnostic of reduced coral competitive fitness across life stages (adults, juveniles, larvae), needed to improve coral reef ecosystem management.Read moreRead less
