Characteristic length scales of marine systems: Can they be measured and what do they mean? A crucial question in ecology is the ?characteristic? scale or scales at which a system should be observed to most clearly observe its deterministic dynamics. We propose to modify methods recently developed for model ecosystems so they may be applied to real ecosystems, assess the performance of these measures in identifying unambiguous length scales, and ascertain what these scales reveal about the under ....Characteristic length scales of marine systems: Can they be measured and what do they mean? A crucial question in ecology is the ?characteristic? scale or scales at which a system should be observed to most clearly observe its deterministic dynamics. We propose to modify methods recently developed for model ecosystems so they may be applied to real ecosystems, assess the performance of these measures in identifying unambiguous length scales, and ascertain what these scales reveal about the underlying ecology. The work will provide significant advances to important applied scaling questions such as the optimal size of reserves and ecosystem management ?units?, and the appropriate scale of observation to detect deterministic trends in ecosystem dynamics.

Tracking squids from embryos to adults - novel approaches and new directions. Cutting edge acoustic tracking technology, combined with traditional tagging techniques and novel applications of trace element analysis, will allow for the life cycle of squid to be tracked through space and time - from embryonic stages through to spawning adults. Southern calamary earbones will be examined for evidence of elemental 'fingerprints' that reveal where they came from as hatchlings. This combined with trac ....Tracking squids from embryos to adults - novel approaches and new directions. Cutting edge acoustic tracking technology, combined with traditional tagging techniques and novel applications of trace element analysis, will allow for the life cycle of squid to be tracked through space and time - from embryonic stages through to spawning adults. Southern calamary earbones will be examined for evidence of elemental 'fingerprints' that reveal where they came from as hatchlings. This combined with tracking squid in Australia's biggest marine acoustic listening grid, will allow unprecedented resolution of squid life cycles. Commercial, recreational and managerial sectors are collaborating with this research to ensure sustainable management of this commercially important and ecologically crucial species.

A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit i ....A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit in areas where a strong need exists for conservation of prey species with economic importance too low to justify expensive at-sea research.Read moreRead less
Restoring diverse native vegetation using drone-based precision seeding . This project aims to make drone technology a viable solution for scaling up the restoration of native vegetation on degraded land. By integrating new research in plant ecology, microbiology and environmental economics the project aims to fill key knowledge gaps about the viability and application of drones in restoration. Expected outcomes are world-first research into the delivery of beneficial soil microbes using drones ....Restoring diverse native vegetation using drone-based precision seeding . This project aims to make drone technology a viable solution for scaling up the restoration of native vegetation on degraded land. By integrating new research in plant ecology, microbiology and environmental economics the project aims to fill key knowledge gaps about the viability and application of drones in restoration. Expected outcomes are world-first research into the delivery of beneficial soil microbes using drones and the first assessment globally of the cost-effectiveness of drone restoration utilizing data from spatial analysis and extensive field trials. This should provide wide-ranging benefits for local land managers restoring remote degraded land and aid in reversing the cumulative effects of habitat loss on biodiversity. Read moreRead less
The recovery of seagrass beds: the role of catchments and options for management responses. Seagrass beds once dominated tidal flats but are disappearing at an increasing rate due to human actions, both in Australia and around the world. This project will develop an understanding of the processes that cause these losses, the factors that prevent seagrass-bed re-establishment, and provide a framework for evaluating alternative management options.

Summary
A high-resolution isotope facility for low cost analysis of water, plant, and soil/sediment samples to understand environmental change. 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 developme ....A high-resolution isotope facility for low cost analysis of water, plant, and soil/sediment samples to understand environmental change. 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
