  abstract  = {Three spinel lherzolite xenoliths from Mt. Quincan (Queensland, northeastern Australia) were studied with special attention to their enclosed fluid inclusions. The xenoliths are deformed, have porphyroclastic textures and overall show very similar petrographic features. The only significant difference is manifested in the abundance of fluid inclusions in the samples, mostly in orthopyroxene porphyroclasts. Xenolith JMTQ11 is fluid inclusion-free, whereas xenolith JMTQ20 shows a high abundance of fluid inclusions (fluid inclusion-rich). Xenolith JMTQ45 represents a transitional state between the previous two, as it contains only a small amount of fluid inclusions (fluid inclusion-bearing). Previous studies revealed that these xenoliths and the entrapped fluid inclusions represent a former addition of a MORB-type fluid to the pre-existing lithosphere, resulting from asthenosphere upwelling. There is a progressive enrichment in LREE, Nb, Sr and Ti from the fluid inclusion-free xenolith through the fluid inclusion-bearing one to the fluid inclusion-rich lherzolite. This suggests an increase in the extent of the interaction between the fluid-rich melt and the lherzolite wallrock. In addition, the same interaction is considered to be responsible for the formation of pargasitic amphibole as well. The presence of fluid inclusions indicates fluid migration at mantle depth, and their association with exsolution lamellae in orthopyroxene suggests fluid entrapment following the continental rifting (thermal relaxation) during cooling. A series of analyses, including microthermometry coupled with Raman spectroscopy, FTIR hyperspectral imaging, and Focused Ion Beam-Scanning Electron Microscopy (FIB-SEM) was carried out on the fluid inclusions. Based on the results, the entrapped high-density fluid is composed of 7589 mol\% CO2, 918 mol\% H2O, 0.11.7 mol\% N-2 and <= 0.5 mol\% H2S with dissolved trace elements (melt component). Our findings suggest that the metasomatic fluid phase could have been either a fluid/fluid-rich silicate melt released from the deeper asthenosphere, or a coexisting incipient fluid-rich silicate melt. Further cooling, possibly due to thermal relaxation and the upward migration of the fluid phase, caused the investigated lherzolites to reach pargasite stability conditions. We conclude that pargasite, even if only present in very limited modal proportions, can be a common phase at spinel lherzolite stability in the lithospheric upper mantle in continental rift back-arc settings. Studies of fluid inclusions indicate that significant CO2 release from the asthenosphere in a continental rifting environment is resulting from asthenosphere upwelling and its addition to the lithospheric mantle together with fluid-rich melt lherzolite interaction that leaves a CO2-rich fluid behind.},

By comparing different pricing and non-pricing water management policies with the help of the Water Integrated Market Model, it is found that the impact of water demand reducing policies is most severe on crops that need to be intensively irrigated and are at the same time less water productive. A combination of increasingly frequent and severe droughts and the application of policies that decrease agricultural water demand, in the same region, will create a situation in which the highly water dependent crops rice and cotton cannot be cultivated at all.},

  abstract  = {Semi-parliamentary government is a distinct executive-legislative system that mirrors semi-presidentialism. It exists when the legislature is divided into two equally legitimate parts, only one of which can dismiss the prime minister in a no-confidence vote. This system has distinct advantages over pure parliamentary and presidential systems: it establishes a branch-based separation of powers and can balance the 'majoritarian' and 'proportional' visions of democracy without concentrating executive power in a single individual. This article analyses bicameral versions of semi-parliamentary government in Australia and Japan, and compares empirical patterns of democracy in the Australian Commonwealth as well as New South Wales to 20 advanced parliamentary and semi-presidential systems. It discusses new semi-parliamentary designs, some of which do not require formal bicameralism, and pays special attention to semi-parliamentary options for democratising the European Union.},

  abstract  = {Terrestrial reptiles are particularly vulnerable to climate change. Their highest density and diversity can be found in hot drylands, ecosystems which demonstrate extreme climatic conditions. However, reptiles are not isolated systems but part of a large species assemblage with many trophic dependencies. While direct relations among climatic conditions, invertebrates, vegetation, or reptiles have already been explored, to our knowledge, species' responses to direct and indirect pathways of multiple climatic and biotic factors and their interactions have rarely been examined comprehensively. We investigated direct and indirect effects of climatic and biotic parameters on the individual (body condition) and population level (occupancy) of eight abundant lizard species with different functional traits in an arid Australian lizard community using a 30-yr multi-trophic monitoring study. We used structural equation modeling to disentangle single and interactive effects. We then assessed whether species could be grouped into functional groups according to their functional traits and their responses to different parameters. We found that lizard species differed strongly in how they responded to climatic and biotic factors. However, the factors to which they responded seemed to be determined by their functional traits. While responses on body condition were determined by habitat, activity time, and prey, responses on occupancy were determined by habitat specialization, body size, and longevity. Our findings highlight the importance of indirect pathways through climatic and biotic interactions, which should be included into predictive models to increase accuracy when predicting species' responses to climate change. Since one might never obtain all mechanistic pathways at the species level, we propose an approach of identifying relevant species traits that help grouping species into functional groups at different ecological levels, which could then be used for predictive modeling.},

  abstract  = {In this thesis, I want to outline the emergence of the Australian national identity in colonial Australia. National identity is not a politically determined construct but culturally produced through discourse on literary works by female and male writers. The emergence of the dominant bushman myth exhibited enormous strength and influence on subsequent generations and infused the notion of "Australianness" with exclusively male characteristics. It provided a unique geographical space, the bush, on and against which the colonial subject could model his identity. Its dominance rendered non-male and non-bush experiences of Australia as "un-Australian." I will present a variety of contemporary voices - postcolonial, Aboriginal, feminist, cultural critics - which see the Australian identity as a prominent topic, not only in the academia but also in everyday culture and politics. Although positioned in different disciplines and influenced by varying histories, these voices share a similar view on Australian society: Australia is a plural society, it is home to millions of different people - women, men, and children, Aboriginal Australians and immigrants, newly arrived and descendents of the first settlers - with millions of different identities which make up one nation. One version of national identity does not account for the multitude of experiences; one version, if applied strictly, renders some voices unheard and oppressed. After exemplifying how the literature of the 1890s and its subsequent criticism constructed the itinerant worker as "the" Australian, literary productions by women will be singled out to counteract the dominant version by presenting different opinions on the state of colonial Australia. The writers Louisa Lawson, Barbara Baynton, and Tasma are discussed with regard to their assessment of their mother country. These women did not only present a different picture, they were also gifted writers and lived the ideal of the "New Women:" they obtained divorces, remarried, were politically active, worked for their living and led independent lives. They paved the way for many Australian women to come. In their literary works they allowed for a dual approach to the bush and the Australian nation. Louisa Lawson credited the bushwoman with heroic traits and described the bush as both cruel and full of opportunities not known to women in England. She understood women's position in Australian society as oppressed and tried to change politics and culture through the writings in her feminist magazine the Dawn and her courageous campaign for women suffrage. Barbara Baynton painted a gloomy picture of the Australian bush and its inhabitants and offered one of the fiercest critiques of bush society. Although the woman is presented as the able and resourceful bushperson, she does not manage to survive in an environment which functions on male rules and only values the economic potential of the individual. Finally, Tasma does not present as outright a critique as Barbara Baynton, however, she also attests the colonies a fascination with wealth which she renders questionable. She offers an informed judgement on colonial developments in the urban surrounds of the city of Melbourne through the comparison of colonial society with the mother country England. Tasma attests that the colonies had a fascination with wealth which she renders questionable. She offers an informed judgement on colonial developments in the urban surrounds of the city of Melbourne through the comparison of colonial society with the mother country England and demonstrates how uncertainties and irritations emerged in the course of Australia's nation formation. These three women, as writers, commentators, and political activists, faced exclusion from the dominant literary discourses. Their assessment of colonial society remained unheard for a long time. Now, after much academic excavation, these voices speak to us from the past and remind us that people are diverse, thus nation is diverse. Dominant power structures, the institutions and individuals who decide who can contribute to the discourse on nation, have to be questioned and reassessed, for they mute voices which contribute to a wider, to the "full", and maybe "real" picture of society.},

  abstract  = {Im Rahmen dieser Doktorarbeit wurden die Hangkarbonate von zwei mioz{\"a}nen heterozoischen Karbonatsystemen n{\"a}her untersucht: die Malta Inselgruppe (zentrales Mittelmeer) und das Marion Plateau (Nordost Australien, ODP Leg 194). Die Auswirkungen der mittelmioz{\"a}nen Abk{\"u}hlung (Mi3), die auf 13.6 Ma datiert wird und starken Einfluß auf die Sauerstoffisotopenkurve hatte, in den oben genannten Flachwassersystemen stellten das Ziel dieser Arbeit dar. Dieses Abk{\"u}hlungsereignis beeinflußte außerdem sehr stark die ozeanographischen und klimatischen Muster, die im weiteren Verlauf zum modernen Eishausklima f{\"u}hrten. So steht insbesondere die Vereisung von Ostantarktika mit diesem Ereignis in Verbindung. Diese Arbeit untersucht den Einfluß dieses Ereignisses auf Flachwassersysteme, um vorliegende Untersuchungen in Tiefwassersystemen zu erg{\"a}nzen und so zum globalen Verst{\"a}ndnis des mioz{\"a}nen Klimawechsels beizutragen. Die Profile auf der Maltainselgruppe wurden mit Hilfe von Kohlenstoff- und Sauerstoffisotopen Auswertungen im Gesamtgestein, Gesamtgesteinmineralogie, Tonmineralanalyse und organischer Geochemie untersucht. Durch einen Wechsel von karbonatischeren zu tonigeren Sedimenten beeinflußte das mittelmioz{\"a}ne Abk{\"u}hlungsereignis die Sedimentation in diesem Gebiet sehr stark. Weiterhin wurde beobachtet, daß jede Phase der antarktischen Vereisung, nicht nur das mittelmioz{\"a}ne Hauptereignis, zu einem erh{\"o}hten terrigenen Eintrag in den Hangsedimenten der Maltainselgruppe f{\"u}hrte. Akkumulationsraten zeigen, daß dieser erh{\"o}hte terrigene Eintrag den einzelnen Vereisungsperioden zusammenh{\"a}ngt und die karbonatischen Sedimente durch tonreiche Sedimente \&ldquo;verunreinigt\&rdquo; wurden. Das daraufhin entwickelte Modell erkl{\"a}rt diesen erh{\"o}hten terrigenen Eintrag mit einer nordw{\"a}rtigen Verlagerung der innertropischen Konvergenzzone durch die Bildung von kalten, dichten Luftmassen, die zu verst{\"a}rkten Niederschl{\"a}gen in Nordafrika f{\"u}hrten. Diese verst{\"a}rkten Niederschl{\"a}ge (oder verst{\"a}rkter afrikanischer Monsun) beeinflußten die kontinentale Verwitterung und den Eintrag, mit der Folge, daß verst{\"a}rkt terrigene Sedimente im Bereich der Hangsedimente der Maltainselgruppe abgelagert wurden. Die tonreichen Intervalle weisen {\"A}hnlichkeiten zu sapropelischen Ablagerungen auf, was mit Hilfe der Spektral analyse des Karbonatgehalts und der geochemischen Analyse des organischen Materials gezeigt wurde. Auf dem Marion Plateau wurden die Sauerstoff- und Kohlenstoffisotopenkurven anhand von Foraminiferen der Gattung Cibicidoides spp. rekonstruiert. Der Karbonatgehalt wurde mit Hilfe einer chemischen Methode (Coulometer) ermittelt. Genauso wie die Sedimente der Maltainselgruppe beeinflußte das mittelmioz{\"a}ne Abk{\"u}hlungsereignis (Mi3) auch die Sedimente auf dem Marion Plateau. So kam es bei 13,8 Ma, in etwa zur Zeit der Vereisung von Ostantarktika, zu einem Abfall der Karbonatakkumulationsraten. Weiterhin traten {\"A}nderungen in der Zusammensetzung der Sedimente auf, so nehmen neritische Karbonatfragmente ab, der planktische Foraminiferengehalt nimmt zu und es wurden verst{\"a}rkt Quarz und Glaukonit abgelagert. Ein {\"u}berraschendes Ergebnis ist die Tatsache, daß der große N12-N14 Meeresspiegelabfall um 11,5 Ma die Akkumulationsraten der Karbonate auf dem Hang nicht beeinflußte. Dieses Ergebnis ist umso erstaunlicher, da Karbonatplattformen normalerweise sehr sensitiv auf Meeresspiegel{\"a}nderungen reagieren. Der Grund, warum sich die Karbonatakkumulationsraten schon um 13,6 Ma (Mi3) und nicht erst um 11,5 Ma (N12-N14) verringerten, liegt in der Tatsache, daß die ozeanischen Str{\"o}mungen die Karbonatsedimentation auf dem Hang des Marion Plateau schon im Mioz{\"a}n kontrollierten. Das mittelmioz{\"a}ne Ereignis (Mi3) erh{\"o}hte die St{\"a}rke diese Str{\"o}mungen und als eine Ursache wurde die Karbonatakkumulation auf den H{\"a}ngen reduziert. Die Amplitude des N12-N14 Meeresspiegelabfalls liegt bei 90 m unter der Ber{\"u}cksichtigung der Sauerstoffisotopendaten aus der Tiefsee und Berechnungen des Meeresspiegels anhand des \&ldquo;coastal onlaps\&rdquo;, die w{\"a}hrend Leg 194 gemacht wurden. Die Isotopendaten dieser Arbeit weisen hingegen auf einen verringerten Meeresspiegelabfall von 70 m hin. Als allgemeine Schlußfolgerung kann gesagt werden, daß der mittelmioz{\"a}ne Klimaumschwung die Karbonatsysteme zumindest an den beiden untersuchten Lokalit{\"a}ten beeinflußt hat. Allerdings waren die Auswirkungen sehr von den unterschiedlichen lokalen Gegebenheiten abh{\"a}ngig. Insbesondere wirkten sich die Anwesenheit einer Landmasse (Malta) und die Abwesenheit einer Barriere vor den Einfl{\"u}ssen des offenen Ozeans (Marion Plateau) stark auf die Ablagerung der Karbonate aus.},

The venomous elapid snakes are among the best-studied organismal groups in this region, but many knowledge gaps persist: for instance, despite their iconic status, the species-level diversity among Australo-Papuan blacksnakes (Pseudechis) has remained poorly understood due to the existence of a group of cryptic species within the P. australis species complex, collectively termed "pygmy mulga snakes". Using two mitochondrial and three nuclear loci we assess species boundaries within the genus using Bayesian species delimitation methods and reconstruct their phylogenetic history using multispecies coalescent approaches. Our analyses support the recognition of 10 species, including all of the currently described pygmy mulga snakes and one undescribed species from the Northern Territory of Australia. Phylogenetic relationships within the genus are broadly consistent with previous work, with the recognition of three major groups, the viviparous red-bellied black snake P. porphyriacus forming the sister species to two clades consisting of ovoviviparous species.},
