The summer of 2003 was an active forest fire season in Siberia. Several events of elevated carbon monoxide (CO) were observed at Rishiri Island in northern Japan during an intensive field campaign in September 2003. A simulation with a global chemistry-transport model is able to reproduce the general features of the baseline levels and variability in the observed CO, and a source attribution for CO in the model suggests that the contribution from North Asia dominated, accounting for approximately 50% on average, with contributions of 7% from North America and 8% from Europe and 30% from oxidation of hydrocarbons. With …


North Polar Frontal Clouds And Dust Storms On Mars During Spring And Summer, Huiqun Wang, Jenny A. Fisher Jan 2009

North Polar Frontal Clouds And Dust Storms On Mars During Spring And Summer, Huiqun Wang, Jenny A. Fisher

Faculty of Science - Papers (Archive)

The complete archive of Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) Mars Daily Global Maps (MDGM) are used to study north polar clouds and dust storms that exhibit frontal structures during the spring and summer (Ls 0–180°). Results show that frontal events generally follow the edge of the polar cap during spring and mid/late summer with a gap in the distribution in early summer. The exact duration and timing of the gap vary from year to year. Twww.lw20.comen to twenty percent of spring and summer time frontal events exhibit complex morphologies. Distinct temperature signatures are associated with features observed …

Inverse modeling of CO2 satellite observations to better quantify carbon surface fluxes requires a chemical transport model (CTM) to relate the fluxes to the observed column concentrations. CTM transport error is a major source of uncertainty. We show that its effect can be reduced by using CO satellite observations as additional constraint in a joint CO2-CO inversion. CO is measured from space with high precision, is strongly correlated with CO2, and is more sensitive than CO2 to CTM transport errors on synoptic and smaller scales. Exploiting this constraint requires statistics for the CTM transport error correlation between CO2 and CO, …

The calculated reservoir ages, rimglng from -60 to +112 years, are much smaller than those for Australian marine shells and not considered significant for the radiocarbon dating of Late Pleistocene freshwater shells from the Murray-Darling Ba,sin.


Invasion And Management Of A Woody Plant, Lantana Camara L., Alters Vegetation Diversity Within Wet Sclerophyll Forest In Southeastern Australia, Ben Gooden, Kris French, Peter J. Turner Jan 2009

Invasion And Management Of A Woody Plant, Lantana Camara L., Alters Vegetation Diversity Within Wet Sclerophyll Forest In Southeastern Australia, Ben Gooden, Kris French, Peter J. Turner

Faculty of Science - Papers (Archive)

Plant invasions of natural communities are commonly associated with reduced species diversity and altered ecosystem structure and function. This study investigated the effects of invasion and management of the woody shrub Lantana camara (lantana) in wet sclerophyll forest on the south-east coast of Australia. The effects of L. camara invasion and management on resident vegetation diversity and recruitment were determined as well as if invader management initiated community recovery. Vascular plant species richness, abundance and composition were surveyed and compared across L. camara invaded, non-invaded and managed sites following L. camara removal during a previous control event by land managers. …


Impact Threshold For An Alien Plant Invader, Lantana Camara L., On Native Plant Communities, Ben Gooden, Kris French, Peter J. Turner, Paul O. Downey Jan 2009

Impact Threshold For An Alien Plant Invader, Lantana Camara L., On Native Plant Communities, Ben Gooden, Kris French, Peter J. Turner, Paul O. Downey

Faculty of Science - Papers (Archive)

Alien plant invaders significantly threaten native community diversity, although it is poorly understood whether invasion initiates a linear or non-linear loss of resident species. Where low abundances of an invader have little impact on native species diversity, then a threshold level may exist, above which native communities rapidly decline. Our aim was to assess the broadscale effects of an alien thicket-forming shrub, lantana (Lantana camara L.), on wet sclerophyll forest in southeastern Australia. Vascular plant species richness, abundance and composition were measured and compared along a gradient of lantana invasion. There was a strong negative non-linear relationship between native species …


Apolipoprotein-E Forms Dimers In Human Frontal Cortex And Hippocampus, David A. Elliott, Glenda M. Halliday, Brett Garner Jan 2009

Apolipoprotein-E Forms Dimers In Human Frontal Cortex And Hippocampus, David A. Elliott, Glenda M. Halliday, Brett Garner

Faculty of Science - Papers (Archive)

Background: Apolipoprotein-E (apoE) plays important roles in neurobiology and the apoE4 isoform increases risk for Alzheimer’s disease (AD). ApoE3 and apoE2 are known to form disulphide-linked dimers in plasma and cerebrospinal fluid whereas apoE4 cannot form these dimers as it lacks a cysteine residue. Previous in vitro research indicates dimerisation of apoE3 has a significant impact on its functions related to cholesterol homeostasis and amyloid-beta peptide degradation. The possible occurrence of apoE dimers in cortical tissues has not been examined and was therefore assessed. Human frontal cortex and hippocampus from control and AD post-mortem samples were homogenised and analysed …

White-rot fungi, unlike bacteria in conventional activated sludge system, can degrade wide varieties of textile dyes. Their large scale implementation, however, has been impeded due to lack of appropriate reactor system that can sustain stable performance under non-sterile environment. In this study, contrary to virtually complete decoloration of an azo dye (Acid Orange II, 100 mg L−1) in pure culture batch test, a fungal membrane bioreactor (MBR) achieved 93% removal during long-term non-sterile operation at a hydraulic retention time (HRT) of 1 d. Through a set of novel observations made in MBR and parallel batch tests, the interrelated factors responsible …

De Novo Synthesis And Degradation Of Lx And V Cycle Pigments During Shade And Sun Acclimation In Avocado Leaves, Britta Forster, C. Barry Osmond, Barry J. Pogson

Faculty of Science - Papers (Archive)

The photoprotective role of the universal violaxanthin cycle that interconverts violaxanthin (V), antheraxanthin (A), and zeaxanthin (Z) is well established, but functions of the analogous conversions of lutein-5,6-epoxide (Lx) and lutein (L) in the selectively occurring Lx cycle are still unclear. We investigated carotenoid pools in Lx-rich leaves of avocado (Persea americana) during sun or shade acclimation at different developmental stages. During sun exposure of mature shade leaves, an unusual decrease in L preceded the deepoxidation of Lx to L and of V to A+Z. In addition to deepoxidation, de novo synthesis increased the L and A+Z pools. …

Nanosized materials are known to take on peculiar properties compared to the bulk material. Their electronic and mechanical properties are known to improve e.g. higher electrical conductivity and greater strength. Their electrochemical redox properties can change dramatically, e.g. in the case of Ag°, the E° value for Ag°→Ag+ + e can change by up to half a volt as the particle size decreases. Nanodimensional materials also have an extraordinarily high surface area to volume ratio. All of these properties would bring beneficial effects if they could be retained when the material is assembled into a structure capable of being …


Climate Change At The Landscape Scale: Predicting Fine-Grained Spatial Heterogeneity In Warming And Potential Refugia For Vegetation, Michael B. Ashcroft, Laurie Chisholm, Kris French Jan 2009

Climate Change At The Landscape Scale: Predicting Fine-Grained Spatial Heterogeneity In Warming And Potential Refugia For Vegetation, Michael B. Ashcroft, Laurie Chisholm, Kris French

Faculty of Science - Papers (Archive)

Current predictions of how species will respond to climate change are based on coarse-grained climate surfaces or idealized scenarios of uniform warming. These predictions may erroneously estimate the risk of extinction because they neglect to consider spatially heterogenous warming at the landscape scale or identify refugia where species can persist despite unfavourable regional climate. To address this issue, we investigated the heterogeneity in warming that has occurred in a 10 km × 10 km area from 1972 to 2007. We developed estimates by combining long-term daily observations from a limited number of weather stations with a more spatially comprehensive dataset …

A transition in hemoglobin (Hb), involving partial unfolding and aggregation, has been shown previously by various biophysical methods. The correlation between the transition temperature and body temperature for Hb from different species, suggested that it might be significant for biological function. In order to focus on such biologically relevant human Hb dynamics, we studied the protein internal picosecond motions as a response to hydration, by elastic and quasielastic neutron scattering. Rates of fast diffusive motions were found to be significantly enhanced with increasing hydration from fully hydrated powder to concentrated Hb solution. In concentrated protein solution, the data revealed that …

Faculty of Science - Papers (Archive)

The receptacle of the sacred lotus is the main source of heat during the thermogenic stage of floral development. Following anthesis, it enlarges, greens and becomes a fully functional photosynthetic organ. We investigated development of photosynthetic traits during this unusual functional transition. There were two distinct phases of pigment accumulation in receptacles. Lutein and photoprotective xanthophyll cycle pigments accumulated first with 64% and 95% of the maximum, respectively, present prior to anthesis. Lutein epoxide comprised 32% of total carotenoids in yellow receptacles, but declined with development. By contrast, more than 85% of maximum total chlorophyll, β-carotene and Rubisco were produced …

Where Is Creativity In The City? Integrating Qualitative And Gis Methods, Christopher R. Gibson, Christopher Brennan - Horley Jan 2009

Where Is Creativity In The City? Integrating Qualitative And Gis Methods, Christopher R. Gibson, Christopher Brennan - Horley

Faculty of Science - Papers (Archive)

This paper discusses a new blend of methods developed to answer the question of where creativity is in the city. Experimentation with new methods was required because of empirical short- comings with existing creative city research techniques; but also to respond to increasingly important questions of where nascent economic activities occur outside the formal sector, and governmental spheres of planning and economic development policy. In response we discuss here how qualitative methods can be used to address such concerns, based on experiences from an empirical project charged with the task of documenting creative activity in Darwinöa small city in Australia's …

Faculty of Science - Papers (Archive)

A flood exceeding the 100 year average recurrence interval in November 2005 led to the failure of an upland peat bog in Waterfall Gully. The area is prone to severe bushfire and flood events and the control dam at the base of First Falls was filled with sediment sourced from Wilson Bog. A resistant quartzite bar at Fourth Falls has formed a natural constriction point against which burnt logs and debris have collected following previous fire events forming a natural dam resulting in sediment/peat accumulation upstream. The failure of the bog was inevitable as the vegetative material in the log-jam …

According to archaeological standards the Blombos Cave was on the south coast of Africa was a rather small dwelling. The footprint measures just over 50 square meters. But what the researchers unearthed in 13 cubic meters of cave floor was enough to revolutionize our knowledge of the history of the human mind. So-called modern behaviour was therefore on much earlier than previously thought. A team led by South African archaeologist Christopher Henshilwood of the African Heritage Research Institute in Cape Town, who also teaches at the University of Bergen (Norway), discovered in the last 15 years in the Blombos Cave …

Background The largest living lizard species, Varanus komodoensis Ouwens 1912, is vulnerable to extinction, being restricted to a few isolated islands in eastern Indonesia, between Java and Australia, where it is the dominant terrestrial carnivore. Understanding how large-bodied varanids responded to past environmental change underpins long-term management of V. komodoensis populations. Methodology/Principal Findings We reconstruct the palaeobiogeography of Neogene giant varanids and identify a new (unnamed) species from the island of Timor. Our data reject the long-held perception that V. komodoensis became a giant because of insular evolution or as a specialist hunter of pygmy Stegodon. Phyletic giantism, coupled with …

Increasing attention is being paid to how workers in the creative industries negotiate transitions from amateur to professional status and seek opportunities for work and spaces for expression that suit artistic desires. The settings have usually been large cities with populations that can support diverse and specialised audiences and subcultural scenes. In this paper, we discuss research where we participated in a music scene, and talked to dance music disc jockeys and venue owners in a small, regional university city - Dunedin. In Dunedin opportunities for musical work are comparatively plentiful but are constrained in a number of ways. Disc …

Solid-State And Solution-Phase Conformations Of Pseudoproline-Containing Dipeptides, James R. Cochrane, Nima Sayyadi, Danielle Skropeta, Peter Turner, Jack K. Clegg, Katrina A. Jolliffe

Faculty of Science - Papers (Archive)

The conformations of 14 threonine-derived pseudoproline-containing dipeptides (including four d-allo-Thr derivatives) have been investigated by NMR. In solution, the major conformer observed for all dipeptides is that in which the amide bond between the pseudoproline and the preceding amino acid is cis. For dipeptides in which the N-terminus is protected, the ratio of cis- to trans-conformers does not depend significantly on the side chain of the N-terminal amino acid, or the stereochemistry of the Thr residue. However, for dipeptides bearing a free N-terminus, there are significant differences in the ratios of cis- to trans-conformers depending on the side chain present. …

Faculty of Science - Papers (Archive)

Contemporary Australian local government faces several daunting problems, not least escalating financial un-sustainability and local infrastructure depletion. The main response of the various state and territory governments has taken the form of a series structural reform programs, with a strong emphasis on forced amalgamation. However, widespread dissatisfaction with the consequences of these compulsory consolidation programs has led to a search for alternative policy solutions based largely on shared services and various types of regional co-operation between local councils. This paper seeks to place proposed ‘regional’ solutions to contemporary problems in historical perspective by providing a comparative account of three distinct …

Thermal Attributes Of Chrysomya Species, James F. Wallman, Leigh Nelson, Mark P. Dowton

Faculty of Science - Papers (Archive)

The correct identification of forensically important arthropods for post-mortem interval estimation is crucial, as the rate of larval development can vary substantially between species. The identification of forensically important blowflies of the genus Chrysomya (Diptera: Calliphoridae) may be hampered by their close morphological similarities, especially as immatures. The aim of this study was to establish whether genetically closely related blowfly species would share similar developmental profiles. This could permit the application of developmental data to a number of closely related species, including those for which thermodevelopmental studies are lacking. If Australian Chrysomya were found to share developmental profiles, identification of …
