An ecological genetic assessment. This project aims to assess the success of restoration in terms of ecological and genetic viability for plant species in the Fitzgerald River–Stirling Range region of Western Australia, where significant investment is being made in restoring connectivity at a landscape scale. The project intends to compare reproductive output, pollinator behaviour, mating, genetic diversity and pollen dispersal in restored sites with those of undisturbed natural vegetation. The project moves measures of restoration success beyond that of population establishment and survival to incorporate the evolutionary processes that provide long-term resilience, persistence and functional integration of restored populations into broader landscapes.Read moreRead less
Dynamic resilience and stability properties of marine systems: the importance of environment-engineer feedbacks in kelp forests. Kelp forests form complex habitats that support diverse, productive and economically important food-webs. This project will determine whether healthy kelp forests engineer their environment to make conditions more suitable for their continued recruitment and survivorship, thus increasing their stability and resilience in response to anthropogenic threats.
Adaptive management of arid and semi-arid ecosystems. Australia’s arid zones contain some of the world’s most threatened ecosystems. Management must begin immediately, but our understanding of these fragile species and ecosystems is currently very limited. This project will develop and apply new research in Adaptive Management (“learning by doing”) to ensure the persistence of these rare places.

Summary
Mechanisms underlying crop pollinator effectiveness in agro-ecosystems. This project aims to understand how pollinators affect fruit quantity and quality. Worldwide, insect pollinators contribute to biodiversity and ecosystem services in production systems, but also cause yield variability in pollinator-dependent crops. Accounting for the combined outcomes of the amount, quality and timing of the pollen transferred by each pollinator visit is a critical but unexplored component of crop pollinati ....Mechanisms underlying crop pollinator effectiveness in agro-ecosystems. This project aims to understand how pollinators affect fruit quantity and quality. Worldwide, insect pollinators contribute to biodiversity and ecosystem services in production systems, but also cause yield variability in pollinator-dependent crops. Accounting for the combined outcomes of the amount, quality and timing of the pollen transferred by each pollinator visit is a critical but unexplored component of crop pollination ecology. This project will quantitatively assess the effectiveness of pollinator communities to determine the importance of pollinator community composition to maximising crop production. This project is expected to protect food resources and economically benefit Australia.Read moreRead less
A general theory for ecological trait-strategy dimensions. This project aims to bridge the gap in understanding of ecological strategies between plant and animal ecology, globally, using ants. It will test how environmental change influences the success of species, based on ecological strategies, and the consequences for ecosystem function. This project is expected to make a significant contribution to generality and prediction in ecology. Expected outcomes of this project include theory deve ....A general theory for ecological trait-strategy dimensions.

It will test how environmental change influences the success of species, based on ecological strategies, and the consequences for ecosystem function. This project is expected to make a significant contribution to generality and prediction in ecology. Expected outcomes of this project include theory development and application and enhanced global networks of trait researchers. Intended benefits include improved ecological theory, an enhanced capacity to predict how global change will affect organisms and increased understanding of the cascading effects of changes for ecosystem function.Read moreRead less
Functional links between estuaries and their catchments: How does land use change affect estuarine ecological and bio-geochemical function? Estuaries are iconic recreational areas of high ecological and socio-economic value. Estuarine health is strongly linked to the catchments that feed them, yet we have no detailed understanding of these links. This project will use a number of state of the art approaches to better understand how land use affects estuarine health.
Does coevolution drive speciation? This project aims to connect micro-evolutionary processes with macro-evolutionary patterns to test the extent to which tightly coupled co-evolutionary interactions between species drive evolutionary diversification. The project will use techniques including the most recent phylogenetic modelling methods, field experiments and molecular genetics. Expected outcomes include advancing understanding of the mechanisms that generate biodiversity and developing new tec ....Does coevolution drive speciation?

This project aims to determine the ecological effects of artificial light at night on coastal marine ecosystems. Artificial light at night is a pervasive stressor that disrupts a fundamental driver of ecological and evolutionary processes: natural light cycles. Using a holistic approach that combines field experiments and microbial ecology, this project will assess impacts of artificial light at multiple levels of biological and ecological organisation. Expected outcomes include new knowledge on how species interactions mediate functional changes in response to an emergent, global stressor. This should provide significant benefits, including enhanced management of coastal systems and the critical services and social benefits they provide.

Species redundancy in response to multiple disturbances. This project aims to elucidate how the context within which disturbances occur affects food web linkages and how these map to responses in ecosystem function. There is a critical need to test the common assumption in environmental management that high biodiversity makes ecosystems resilient to disturbances.

This project aims to elucidate how the context within which disturbances occur affects food web linkages and how these map to responses in ecosystem function. There is a critical need to test the common assumption in environmental management that high biodiversity makes ecosystems resilient to disturbances. Studies that merely observe biodiversity change after disturbance cannot identify ecological processes connecting high diversity and ecosystem function, making experiments that manipulate identical disturbances in ecosystems with different biodiversity essential. This project will use field experiments that manipulate disturbances in streams replicated in low and high biodiversity regions and across gradients of chronic background stress to show how biodiversity sustains functional ecosystems, and how much diversity can be lost before ecosystems collapse.Read moreRead less

The most significant environmental challenges facing Australia include ensuring sustainable management of our water resources and conservation of both terrestrial and marine biodiversity, particularly in the face of our changing climate and land-use. The new instruments will accelerate progress across a number of projects aimed at understanding the development of groundwater resources, the relative dependency of ecosystems on groundwater versus soil and surface water, and an assessment of the likely impacts of altered hydrology, especially dewatering and salinisation, on ecosystems. In addition, they will also be used to extend our knowledge of climate variability in the recent past and increase understanding of critical marine resources.Read moreRead less
