Resolving the role of kelp in blue carbon cycles to enable management. We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We wil ....Resolving the role of kelp in blue carbon cycles to enable management. We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We will also assess the risk that calcification and production of halogenic gas within the kelp forest could offset its climate mitigation potential. Project outcomes will enable management to consider kelp ecosystem services broadly and optimize our capacity to meet current emission reduction and biodiversity commitments.Read moreRead less
Can consistent individual differences in metabolic rate explain animal personality? Implications for fish and aquaculture in a warming climate. This project will determine if consistent individual differences in metabolic rate affect behaviour, growth, and reproduction in fish. If so, then we need to prepare for the fact that a warming climate will lead to reductions in fish growth and reproduction, because rising temperature directly increases metabolism and therefore maintenance costs.
Turf Wars: fighting the new battle facing blue forests. This project aims to use ecological models and field experiments to uncover drivers and critical thresholds for turf expansion. Habitat loss is a leading threat to goods and services from the oceans. Globally, kelp forests are collapsing and being replaced by persistent unwanted algal ‘turfs’. Understanding of this habitat shift is rudimentary, and solutions to mitigate the impacts virtually non-existent. Through stress experiments and geno ....Turf Wars: fighting the new battle facing blue forests. This project aims to use ecological models and field experiments to uncover drivers and critical thresholds for turf expansion. Habitat loss is a leading threat to goods and services from the oceans. Globally, kelp forests are collapsing and being replaced by persistent unwanted algal ‘turfs’. Understanding of this habitat shift is rudimentary, and solutions to mitigate the impacts virtually non-existent. Through stress experiments and genomic analyses, this project aims to discover resilient kelps that promote forest persistence under stress. By expanding our understanding of critical habitat transitions, and exploring new solutions, this project aims to enhance our capacity to respond to the ongoing degradation of Australia’s Great Southern Reef.Read moreRead less
