An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host ....An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host and symbiont response to changing water temperature along a latitudinal gradient. The intended outcome of the project is to provide knowledge to support predictions of likely species migrations from tropical to subtropical waters, enabling managers to anticipate the future response of coral communities to seawater warming.Read moreRead less
Biotic connectivity within the temperate Australian marine protected area network at three levels of biodiversity, communities, populations and genes. Project outcomes will improve management of coastal biodiversity through a multi-state collaboration of managers, marine ecologists, population geneticists and taxonomists. Sites most needed within marine protected area (MPA) networks for maintaining resilience of populations across seascapes will be identified, including sites with exceptional en ....Biotic connectivity within the temperate Australian marine protected area network at three levels of biodiversity, communities, populations and genes. Project outcomes will improve management of coastal biodiversity through a multi-state collaboration of managers, marine ecologists, population geneticists and taxonomists. Sites most needed within marine protected area (MPA) networks for maintaining resilience of populations across seascapes will be identified, including sites with exceptional endemism or key roles in dispersal of larvae. The ecological efficacy of the temperate Australian MPA network will be assessed through analysis of long-term ecological datasets and further development of a novel 'remote sensing' methodology, whereby surveys are undertaken by volunteer divers across much greater spatial and temporal scales than could be studied by dedicated scientific dive teams.Read moreRead less
Explaining biodiversity. Why are there many species in some places and not in others? The aim of this project is to understand this in order to protect species, understand invasion and restore ecological systems. Using published food webs, this project will determine what factors underlie biodiversity, then use experiments to understand effects of habitat loss and climate change on food web structure.
Dining with Dasyurids: Using Nutritional Geometry to Improve Diets for Captive Breeding Programs. Captive breeding programs are an important part of conservation and reintroduction plans for endangered Northern quolls and Tasmanian devils. This project aims to initiate new collaboration between the Charles Perkins Centre and Taronga Conservation Society to improve diets for captive breeding of marsupial carnivores using the framework of nutritional geometry. Specifically, the project aims to: qu ....Dining with Dasyurids: Using Nutritional Geometry to Improve Diets for Captive Breeding Programs. Captive breeding programs are an important part of conservation and reintroduction plans for endangered Northern quolls and Tasmanian devils. This project aims to initiate new collaboration between the Charles Perkins Centre and Taronga Conservation Society to improve diets for captive breeding of marsupial carnivores using the framework of nutritional geometry. Specifically, the project aims to: quantify the macronutrient (carbohydrate, lipid and protein) targets and regulatory behaviour of marsupial carnivores; test explanations for why animals are prone to excess weight gain in captivity; and quantify changes in nutrient targets with reproduction. These results aims to be applied by Taronga to improve captive-diets for marsupial carnivore breeding programs.Read moreRead less
Understanding snow gum dieback for effective and integrated management. The project leverages recent research and infrastructure investments and our determined and collaborative team as it aims to: 1) assess the future geography of snow gum dieback in the high country and identify priority locations for pro-active management, 2) quantify the impact of snow gums on high country water and carbon budgets and thus the socio- economic and biodiversity values, and 3) determine options for mitigation. ....Understanding snow gum dieback for effective and integrated management. The project leverages recent research and infrastructure investments and our determined and collaborative team as it aims to: 1) assess the future geography of snow gum dieback in the high country and identify priority locations for pro-active management, 2) quantify the impact of snow gums on high country water and carbon budgets and thus the socio- economic and biodiversity values, and 3) determine options for mitigation. Dieback of our iconic snow gum forests is diminishing the ecological, hydrological and cultural values of the Australian Alps and will impact state and national water-supply and power-generation systems. Our research will inform Alps-wide management efforts designed for long-term success.Read moreRead less
How arid zone wetlands persist: linking ecological dynamics with hydrological regimes . This project will investigate how aquatic food webs assemble and persist in mound springs, relict streams and river pools in the Australian arid zone. Knowing how aquatic systems respond to wet and dry phases is the first step towards ‘climate proofing ’ these systems against future extreme events.
Quantifying the threat posed by feral cats to Australian reptiles. This project aims to provide the first quantification of the impact of feral cats on Australian reptiles, the country’s most diverse vertebrate lineage. This project expects to provide crucial missing pieces of the puzzle by adopting an innovative behavioural approach to determine how cats hunt for lizards, and how lizards respond to cat predation risk. The expected outcomes are an improved understanding of the capacity of native ....Quantifying the threat posed by feral cats to Australian reptiles. This project aims to provide the first quantification of the impact of feral cats on Australian reptiles, the country’s most diverse vertebrate lineage. This project expects to provide crucial missing pieces of the puzzle by adopting an innovative behavioural approach to determine how cats hunt for lizards, and how lizards respond to cat predation risk. The expected outcomes are an improved understanding of the capacity of native lizards to recognise cats as predators and respond appropriately, and a determination of the magnitude of threat that cats pose to native lizards. Importantly, our study aims to trial management strategies to mitigate the impact of cat predation on native reptiles.Read moreRead less
Overcoming multiple constraints to wetland forest restoration. This project aims to determine the efficacy of different approaches for restoring wetland forests at the landscape scale. The death and decline of Victoria’s wetland forests, crucial habitat for the endangered helmeted honeyeater and Leadbeater's possum, most likely result from modified flooding patterns, low native tree and shrub recruitment and increased competition from understorey plants. The project intends to reinstate a more n ....Overcoming multiple constraints to wetland forest restoration. This project aims to determine the efficacy of different approaches for restoring wetland forests at the landscape scale. The death and decline of Victoria’s wetland forests, crucial habitat for the endangered helmeted honeyeater and Leadbeater's possum, most likely result from modified flooding patterns, low native tree and shrub recruitment and increased competition from understorey plants. The project intends to reinstate a more natural flood regime, planting native species and reducing competition from dense understorey vegetation. In this way, the project aims to test and advance ecological theory, guide wetland restoration and inform management plans for saving Victoria’s iconic fauna.Read moreRead less

Comparative population structure of forest invertebrate species - habitat specific or species specific? Invertebrates that colonize decomposing logs are an important link in the food chain and major players in the recycling of forest debris. In addition, many threatened species occupy this habitat. Despite their undoubted economic and conservation significance, there is very little information on distribution, dispersal and population structure for any of these species. We will use genetic tool ....Comparative population structure of forest invertebrate species - habitat specific or species specific? Invertebrates that colonize decomposing logs are an important link in the food chain and major players in the recycling of forest debris. In addition, many threatened species occupy this habitat. Despite their undoubted economic and conservation significance, there is very little information on distribution, dispersal and population structure for any of these species. We will use genetic tools to investigate these patterns, and to determine whether they are specific to particular species, or the product of the habitat itself. Our results will indicate whether forest management strategies should focus on the preservation of individual species or their habitat.Read moreRead less
