Ecophysiological limitations that affect water and carbon balance within large tree canopies: a comparative investigation. Supply of water to forest canopies is a major control of hydrological, atmospheric and biotic processes that impinge on groundwater stability, catchment yield, the fate of pollutants and plant productivity. Fundamental aspects of water transport and distribution within plant tissues remain obscured by conflicting experimental data and conflicting theoretical models that des ....Ecophysiological limitations that affect water and carbon balance within large tree canopies: a comparative investigation. Supply of water to forest canopies is a major control of hydrological, atmospheric and biotic processes that impinge on groundwater stability, catchment yield, the fate of pollutants and plant productivity. Fundamental aspects of water transport and distribution within plant tissues remain obscured by conflicting experimental data and conflicting theoretical models that describe physiological functioning.
Potential hydraulic constraints to the exchange of water and carbon between leaf and atmosphere require investigation before accurate models and informed decisions can be made with respect to the role of forests in biosphere-atmosphere processes. I will use large trees to investigate physiological and morphological determinants of hydraulic function and consider relationships between tree size, water requirements and water supply.
This project will foster comparative analyses of hydraulic functioning in large angiosperm and conifer species to elucidate universal principles that relate form to function and explain relationships between trees and their environment.

Ocean Acidification in a Rapidly Increasing CO2 World. Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critica ....Ocean Acidification in a Rapidly Increasing CO2 World. Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critical threshold limits of CO2 emissions for sustainable calcification in both shallow tropical and deep-water marine ecosystems of the Southern Oceans.Read moreRead less
Rushdie Annotated: Definitive explanations of all obscure references in the Salman Rushdie corpus and extended critical commentaries on the author. In an Australia where the literary work of art now attends to issues which are multicultural, this reference text on Rushdie would show how crucial the creative use of language is in the formation of cultural identity. As a key spokesperson for liberal values, Rushdie and his works are informed by those communal values which have a direct bearing on ....Rushdie Annotated: Definitive explanations of all obscure references in the Salman Rushdie corpus and extended critical commentaries on the author. In an Australia where the literary work of art now attends to issues which are multicultural, this reference text on Rushdie would show how crucial the creative use of language is in the formation of cultural identity. As a key spokesperson for liberal values, Rushdie and his works are informed by those communal values which have a direct bearing on definitions of the Australian nation state. Ongoing debates in Australia about citizenship in a globalized world, about the relative autonomy of the literary work of art, about the links between culture and religion find valuable expression in Rushdie's works.Read moreRead less

Sugar and water handling by honeyeaters and sunbirds. Honeyeaters are the major vertebrate pollinators in Australia, playing a vital role in maintenance of healthy ecosystems. These birds are faced with extreme physiological challenges due to their diet, ingesting 2-5 times their body mass in nectar to obtain their daily sugar requirement. Nectarivores are, consequently, masters at processing and assimilating sugars and water; comparative physiology of these charismatic birds will provide deep u ....Sugar and water handling by honeyeaters and sunbirds. Honeyeaters are the major vertebrate pollinators in Australia, playing a vital role in maintenance of healthy ecosystems. These birds are faced with extreme physiological challenges due to their diet, ingesting 2-5 times their body mass in nectar to obtain their daily sugar requirement. Nectarivores are, consequently, masters at processing and assimilating sugars and water; comparative physiology of these charismatic birds will provide deep understanding of sugar and water handling mechanisms. Understanding gut and renal physiology and morphology contributes to the broad base of knowledge required to address pathological and clinical conditions in man, and will enhance our ability to predict effects of environmental change on these birds.Read moreRead less

Indonesia in exile: The Indonesian Left abroad during the late Cold War. Since ousting President Suharto in 1998 Indonesians have been striving to make sense of a turbulent political past and re-evaluating long-held assumptions, including about communism. After decades of political suppression, there are signs some new form of polity will emerge in which a long-suppressed Left might play a part and which Australia needs to understand.

Since ousting President Suharto in 1998 Indonesians have been striving to make sense of a turbulent political past and re-evaluating long-held assumptions, including about communism. After decades of political suppression, there are signs some new form of polity will emerge in which a long-suppressed Left might play a part and which Australia needs to understand. Since diasporic, exilic communities are a potential source of inter-state tension, and possible irritant in Australian-Indonesian relations, it is important for Australia to understand the role such communities may play in sustaining and transmitting alternative political visions, and in challenging the state.

The world faces enormous environmental and clinical challenges that require accurate data from remote deployable and disposable sensors. Many key parameters important to global warming (carbon dioxide cycle) and clinical diagnostics (blood electrolytes) may be assessed with a polymeric membrane sensing technology, but the measurement principle is not sufficiently robust for remote sensing applications. This research will make this possible by adapting calibration free measurement principles (coulometry, or charge counting) to this class of sensors, where a thin layer of sample solution will be depleted by instrumental control. This forms the scientific basis for successfully tackling the measurement challenges of the future.Read moreRead less
Understanding the impact of heat stress on cognition in a changing world. Our research will determine how anthropogenic climate change effects the ability of animals to process information in their environment. This research is significant because it directly addresses the growing issue of wildlife adaptation to climate change.

Our research will determine how anthropogenic climate change effects the ability of animals to process information in their environment. This research is significant because it directly addresses the growing issue of wildlife adaptation to climate change. If heat stress, reported widely in wildlife both in Australia and globally, impairs an animal's ability to respond to stimuli in its surrounding environment, then this may cause lower reproductive success (eg lower predator detection rates) and population declines. We aim to identify critical temperature points beyond which the cognitive responses of animals decline rapidly - a significant finding for effective wildlife management priorities in the face of rapid climate change.
