Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind. Substantial emission reduction must be achieved, with responsibilities to be shared by all sectors. Rivers, estuaries and water storages contribute considerably to global nitrous oxide and methane emissions, much of which is anthropogenic contributed by urban and agricultural run-off and wastewater discharges. Through an in-depth study on several rivers, estuaries and reservoirs in South East Queensland, this project will provide data to enable reliable estimation of such emissions in Australia, and deliver knowledge and tool support for the development of strategic catchment management strategies.Read moreRead less
Conserving native wildlife during urbanisation: the effectiveness of biodiversity-friendly urban design and construction practices. Urbanisation has many negative effects upon native wildlife and their habitats, but biodiversity-friendly urban design and construction practices may greatly reduce these impacts. This study will examine the effectiveness of such measures at sustaining wildlife at sites of urban development, and will therefore produce significant benefits for local residents and the ....Conserving native wildlife during urbanisation: the effectiveness of biodiversity-friendly urban design and construction practices. Urbanisation has many negative effects upon native wildlife and their habitats, but biodiversity-friendly urban design and construction practices may greatly reduce these impacts. This study will examine the effectiveness of such measures at sustaining wildlife at sites of urban development, and will therefore produce significant benefits for local residents and the broader Australian community. Healthy natural ecosystems in urban areas provide many services to the public, reduce the need for costly management, and improve the livelihood of residents living in greener environments. This study will enhance all these community benefits through a detailed examination of the effectiveness of biodiversity-friendly urban development measures.Read moreRead less

Greenhouse gases threaten the global climate. Many estimates of vegetation as sinks and sources for greenhouse gases have a high degree of uncertainty. This project will generate important information about greenhouse gas emissions from Queensland coastal vegetation. Characterised by moist and nutrient rich conditions, sugarcane fields and mangrove ecosystems represent significant sources/sinks of potent greenhouse gases nitrous oxide and methane. Sugarcane and mangroves exposed to different nutrient inputs will allow to (i) identify mechanisms of N2O and CH4 emission, (ii) model N2O and CH4 emissions under different nutrient and climate conditions, and (iii) control/reduce emissions by improving coastal ecosystem management.Read moreRead less
Environmental drivers for production of the toxin, cylindrospermopsin, by the cyanobacterium Cylindrospermopsis raciborskii. Water authorities spend significant resources to monitor and control algal blooms. A significant part of this is monitoring freshwater toxic algal blooms that can impact on drinking water and recreational uses. One of the difficulties in monitoring blooms is that the toxin content of individual species can vary considerably. It is unclear whether this is caused by changes ....Environmental drivers for production of the toxin, cylindrospermopsin, by the cyanobacterium Cylindrospermopsis raciborskii. Water authorities spend significant resources to monitor and control algal blooms. A significant part of this is monitoring freshwater toxic algal blooms that can impact on drinking water and recreational uses. One of the difficulties in monitoring blooms is that the toxin content of individual species can vary considerably. It is unclear whether this is caused by changes in environmental conditions, i.e. nutrient, light, temperature. This project would provide the link between environmental conditions and toxin production to improve the ability to predict and monitor toxin production.Read moreRead less
