Ecological and genetic connectivity in seagrasses: the role of sexual reproduction, dispersal and recruitment on meadow restoration. This project's goal is to study the role of dispersal in contemporary demographics and genetics of an Australian seagrass genus Posidonia. The expected outcome of this project is to understand the importance of long-distance dispersal of seeds in determining resilience of seagrasses to both natural and anthropogenic disturbances.

This project aims to examine the factors that influence conservation in multiple-use zones, using a functional habitat approach to study hollow-dependent black-cockatoos and parrots in the jarrah forest of south-western Australia as a model system.

Changing water availability and the conservation of wide-ranging species. This project aims to examine the factors that influence conservation in multiple-use zones, using a functional habitat approach to study hollow-dependent black-cockatoos and parrots in the jarrah forest of south-western Australia as a model system. It will focus on how water availability influences landscape use, and its potential as a management tool, and use this information to effectively conserve wide-ranging species in multiple-use landscapes in a changing climate. The project is anticipated to reduce the negative effects of competing land uses on biodiversity and improve the efficiency of conservation and landscape management.Read moreRead less
The role of plant-soil feedback in biodiversity maintenance along fertility gradients: from patterns to mechanisms. Plants strongly modify soils and their associated biota, which in turn has important consequences for plant growth. This is known as 'plant-soil feedback'. This project will determine whether such feedback plays a role in maintaining the exceptionally high levels of plant biodiversity found in the kwongan shrublands of south-western Australia.
Understanding coastal biodiversity: The impact of marine production subsidies upon arid coastal environments. Many of the Earth's coastlines have productive seas next to arid terrestrial habitats. Much of the coastline of Western Australia is arid. Our project will determine if biodiversity in fringing terrestrial areas is controlled by the supply of marine plant material that is transported to land by waves, wind and birds. A consequence of increasing coastal usage is associated growing anthrop ....Understanding coastal biodiversity: The impact of marine production subsidies upon arid coastal environments. Many of the Earth's coastlines have productive seas next to arid terrestrial habitats. Much of the coastline of Western Australia is arid. Our project will determine if biodiversity in fringing terrestrial areas is controlled by the supply of marine plant material that is transported to land by waves, wind and birds. A consequence of increasing coastal usage is associated growing anthropogenic pressures on the coastal environment. Our aim is to enhance awareness of the interactions that occur between terrestrial and marine systems, and hence to increase the capacity of the public and private sector to manage marine and terrestrial ecosystems, and the interface between them.Read moreRead less

Summary
Assessing pollination services of honey bees in native ecosystems and threats posed by parasites. The European honeybee is our most abundant pollinator but we know little about its role in native Australian ecosystems or how its many diseases may affect its ability to pollinate. This project will determine whether honeybees are important pollinators of native plants and how a common parasite affects their pollination ability.
Novel species interactions arising from synergistic environmental changes. Synergistic environmental changes, including climate and land use change, are altering Australia's ecosystems and creating novel species assemblages. We know little about how these assemblages develop and function, and yet they are likely to become more pervasive and provide a significant conservation and restoration challenge. We aim to improve our understanding of the factors affecting the creation of novel plant assemb ....Novel species interactions arising from synergistic environmental changes. Synergistic environmental changes, including climate and land use change, are altering Australia's ecosystems and creating novel species assemblages. We know little about how these assemblages develop and function, and yet they are likely to become more pervasive and provide a significant conservation and restoration challenge. We aim to improve our understanding of the factors affecting the creation of novel plant assemblages (through invasions and changes in species' ranges) in the York Gum woodlands of Western Australia. We will examine how novel assemblages function, improve the ability to predict potential ongoing changes in assemblages and provide guidance for the management of these and other internationally important plant communities.Read moreRead less
Testing the Flood Pulse Concept for rivers with variable flow regimes. For floodplain rivers the major unifying conceptual model linking hydrology, biogeochemistry and ecology is the Flood Pulse Concept (FPC). The model is based on rivers that have a seasonally predictable and long duration inundation of floodplain habitats. Recent reviews of the FPC indicate that the model needs to be broadened to describe the function of rivers with more variable flow regimes. This project will test some of th ....Testing the Flood Pulse Concept for rivers with variable flow regimes. For floodplain rivers the major unifying conceptual model linking hydrology, biogeochemistry and ecology is the Flood Pulse Concept (FPC). The model is based on rivers that have a seasonally predictable and long duration inundation of floodplain habitats. Recent reviews of the FPC indicate that the model needs to be broadened to describe the function of rivers with more variable flow regimes. This project will test some of the predictions of the FPC for variable dryland rivers by investigating how food webs in the channels of a floodplain reach respond to flows of different magnitude, seasonal timing and duration.Read moreRead less

This project aims to develop a model for urban ecosystem function and restoration, by identifying resources used by urban bandicoots (quenda).

Backyard bandicoots: Engaging community in urban bushland conservation. This project aims to develop a model for urban ecosystem function and restoration, by identifying resources used by urban bandicoots (quenda). Digging mammal species turn over substantial volumes of soil as they forage for invertebrates, subterranean fungi, and plant material. These ecosystem engineers contribute to water infiltration, nutrient cycling, increased soil microorganism function, and seedling recruitment. They spread hypogeous mycorrhizal fungi that contribute to plant nutrition, crucial in Australia's nutrient-poor soils. This research is expected to improve targeted plantings in bushland reserves, and identify and mitigate threats to bandicoots in cities.Read moreRead less

Summary
Understanding the origin and maintenance of megadiverse plant communities. South-western Australia hosts some of the most biologically diverse plant communities on Earth, and these occur on the most ancient, nutrient-impoverished soils. By studying coastal dunes of increasing age, this project will determine how megadiverse plant communities originate during long-term ecosystem development, and how they are maintained.
Integrating seagrass recruitment and growth at the shoot scale with temporal and spatial dynamics of seagrass meadows in marine landscapes. In Australia, seagrass loss associated with human activity is one of the most serious issues affecting the marine environment. Despite this, processes contributing to maintenance of seagrass meadows are poorly understood. This project addresses meadow maintenance through measuring seedling recruitment, clonal growth and patch dynamics for 3 species of seagra ....Integrating seagrass recruitment and growth at the shoot scale with temporal and spatial dynamics of seagrass meadows in marine landscapes. In Australia, seagrass loss associated with human activity is one of the most serious issues affecting the marine environment. Despite this, processes contributing to maintenance of seagrass meadows are poorly understood. This project addresses meadow maintenance through measuring seedling recruitment, clonal growth and patch dynamics for 3 species of seagrasses, and modeling emergent patterns of meadow expansion. The outcomes will be integration of shoot-scale and meadow-scale dynamics in shallow subtidal landscapes, resulting in a clearer understanding of and ability to manage large-scale changes in seagrass meadows caused by natural and anthropogenic influences.
