Shallow water carbonate sediment dissolution in the global carbon cycle. Carbonate sediment dissolution is a globally significant process, but poorly understood in shallow marine waters. This project will determine whether the combined effect of organic matter, ocean acidification and pore water flow in shallow water carbonate sediments increases the release of calcium and alkalinity to the ocean. This project is significant because this release has not previously been accounted for and may lead ....Shallow water carbonate sediment dissolution in the global carbon cycle. Carbonate sediment dissolution is a globally significant process, but poorly understood in shallow marine waters. This project will determine whether the combined effect of organic matter, ocean acidification and pore water flow in shallow water carbonate sediments increases the release of calcium and alkalinity to the ocean. This project is significant because this release has not previously been accounted for and may lead to an additional uptake of atmospheric carbon dioxide into the global ocean, maybe some additional buffering against ocean acidification, but unfortunately, maybe also a loss of carbonate ecosystems. The outcomes of this project will make a significant contribution to our understanding of the global carbon cycle.

Multitrophic interactions drive diversity-ecosystem function relationships. Soil communities, among the most abundant and diverse in nature are responsible for many critical ecosystem functions, including nutrient cycling and climate regulation.

Soil communities, among the most abundant and diverse in nature are responsible for many critical ecosystem functions, including nutrient cycling and climate regulation. This project will determine whether consideration and quantification of interactions between different biotic communities – specifically among plants, soil microbes and animals, within and across trophic levels - can address underlying shortcomings in predictions from classical biodiversity-ecosystem function theory. By advancing understanding of biological complexity and its impacts on ecosystem functions, the project will provide a unifying framework for understanding variation in ecosystem functions across scales, ecosystem types and multiple environmental disturbances.Read moreRead less
Congestion control in complex networks with higher-order interactions. Traffic congestion significantly costs the Australian economy and environment.

Small but bold: harnessing microbes to boost drought tolerance in grasses . Drought threats grasslands worldwide, and new adaptation and resilience building approaches are required to protect the wealth of ecosystem services provided by grasslands. Soil microbes offer an untapped opportunity to enhance drought survival in grasses. Yet, to harness this potential, we first need to identify the key microbial functions that contribute to plant tolerance to drought.

Drought threats grasslands worldwide, and new adaptation and resilience building approaches are required to protect the wealth of ecosystem services provided by grasslands. Soil microbes offer an untapped opportunity to enhance drought survival in grasses. Yet, to harness this potential, we first need to identify the key microbial functions that contribute to plant tolerance to drought. This project aims to determine the microbe-mediated ecological and functional mechanisms that underpin grass performance under drought. This knowledge will lay the foundation to accelerate the design and implementation of effective microbial manipulations and management strategies, and thus increase our success in protecting this important ecosystem.Read moreRead less
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.
