Abbi Scott

Graduated 2021

Thesis

Herbivores as ecosystem engineers in tropical seagrass meadows: Grazing impacts on meadow structure and ecosystem service delivery

Abbi’s work investigated how herbivores affect seagrass meadows around the Great Barrier Reef to understand their impact on the provision of ecosystem services, specifically focusing on how carbon storage in seagrass meadows can be modified by grazing activity. Her research will inform management measures that seek to maintain ecosystem function and understand potential trade-offs in ecosystem service delivery.

Graduated 2021

Thesis

Microbiology and greenhouse gas dynamics of inland wetlands

Giuditta’s PhD thesis involved: 1) improving inland wetlands activity efficiency by properly optimizing carbon sequestration as well as reducing to minimum the greenhouse gases release, 2) identifying key microbial communities and genes that are highly considered to be involved in carbon metabolism, 3) providing new standards and major advantages to scientific community through the constant monitoring of carbon fluxes field from the Australian floodplain freshwater wetlands.

Ashley Whitt

Graduated 2021

Thesis

Ashley’s career as a coastal ecologist has focused on understanding anthropogenic impacts to coastal communities in oyster reefs, seagrass, saltmarsh and mangroves. Her thesis developed fundamental knowledge of how coastal catchments should be managed to protect and conserve important coastal vegetated habitats under future climate change.

Graduated 2021

Thesis

Reducing emission from degraded wetlands

Katy’s thesis involved modeling carbon sources and sinks from freshwater wetland ecosystems of Southeastern Australia. The aim of this project is to identify long-term carbon storage by analyzing carbon sequestration rates of various inland wetland ecosystems. This connection must be studied to gather knowledge of its significance, and to provide information for better wetland ecosystem management practices.

Graduated 2020

Thesis

Value of Australian coastal ecosystems for fish and fisheries

Holger’s PhD research valued Australia’s coastal ecosystems in relation to fish production using ecological, social, and economic measures. He systematically gathered and synthesized existing fisheries datasets to summarise interactions between fish and coastal ecosystems. Results were combined with socio-economic analysis to advocate for ecosystem-based decision making.

Thesis

Blue Carbon Offset Opportunities within the Corangamite Catchment

Quinn investigated opportunities for carbon offsetting within blue carbon ecosystems of the Corangamite Catchment region in Victoria. He quantified blue carbon stocks and fluxe,s and identified possible mechanisms for the future management of these ecosystems that will aid in the mitigation of carbon re-mineralisation (CO2 released to the atmosphere) and climate change.

Carolyn Ewers Lewis

Graduated 2018

Thesis

Distribution, drivers and disturbance of “blue carbon” in southeast Australia.

Carolyn’s thesis focused on understanding the dynamics of carbon sequestration in saltmarshes, mangroves, and seagrasses in Australia.  Her research involved undergoing a comprehensive, large-scale sampling campaign of 96 blue carbon ecosystems across a data-deficient region of southeast Australia, applying these data to create predictive models and produce high-resolution carbon stock maps, and using paleoanalytical techniques and laboratory simulations to measure the impacts of ‘reclamation’ and erosion on blue carbon stocks, respectively.
