description: Resistively Detected Nuclear Magnetic Resonance (RD-NMR) has been used to investigate a two-subband electron system in a regime where quantum Hall pseudo-spin ferromagnetic (QHPF) states are prominently developed. It reveals that the easy-axis QHPF state around the total filling factor $ν=4 $ can be detected by the RD-NMR measurement. Approaching one of the Landau level (LL) crossing points, the RD-NMR signal strength and the nuclear spin relaxation rate $1/T_{1}$ enhance significantly, a signature of low energy spin excitations. However, the RD-NMR signal at another identical LL crossing point is surprisingly missing which presents a puzzle.

Genetic basis of the effect of alkylating agents on gametogenesis in drosophila melanogaster
Creators: name: Schewe, Michael Joseph
Publisher: name: University of British Columbia
Year: 2011

description: The antibiotic, Mitomycin-C (MC), increases recombination in Drosophila females, yet has no effect on crossing over in males. This sexual difference in recombinagenic response to MC cannot be attributed to a sex difference in permeability to MC, since MC is mutagenic in both sexes. MC increases the frequency of exchange events involving X and Y chromosomes as well as those involving the two arms of the Y in both sexes. On the basis of brood analysis it was found that those cells which are most sensitive to the recombinagenic and X-Y and Y-Y exchange effects of MC were in a premeiotic stage of gametogenesis at the time of treatment. It is proposed that the apparent inability of MC to induce crossovers in males is related to the normal absence of spontaneous meiotic crossing over in males. MC can act as a monofunctional or as a bifunctional alkylating agent which primarily reacts with guanine residues of DNA. Bifunctional alkylation results in the crosslinking of the two strands in the DNA double helix. It is postulated that prior to meiosis, alkylated guanine residues are excised from the DNA molecule through the action of natural repair mechanisms. Depending on whether mono or bifunctional alkylation has taken place, either single strand nicks or double strand cuts will be induced in the DNA. Double strand cuts may be repaired as a mutation or as a non-reciprocal exchange event whereas single strand nicks might act as the natural pre-condition for genuine meiotic crossovers and could thus form crossovers when the necessary "crossover substances" are present. This model predicts that an alkylating agent such as ethyl methanesulfonate (which alkylates guanine monofunction-ally, and therefore would give rise to single strand nicks following excision), should be recombinagenic in females, but not in males but should not effect the frequency of X-Y and Y-Y exchange events in either sex. This prediction was indeed demonstrated thus supporting the model.
Model space truncation in shell-model fits

description: We carry out an interacting shell-model study of binding energies and spectra in the $sd$-shell nuclei to examine the effect of truncation of the shell-model spaces. Starting with a Hamiltonian defined in a larger space and truncating to the $sd$ shell, the binding energies are strongly affected by the truncation, but the effect on the excitation energies is an order of magnitude smaller. We then refit the matrix elements of the two-particle interaction to compensate for the space truncation, and find that it is easy to capture 90% of the binding energy shifts by refitting a few parameters. With the full parameter space of the two-particle Hamiltonian, we find that both the binding energies and the excitation energy can be fitted with remaining residual error about 5% of the average error from the truncation. Numerically, the rms initial error associated with our Hamiltonian is 3.4 MeV and the remaining residual error is 0.16 MeV. This is comparable to the empirical error found in $sd$-shell interacting shell model fits to experimental data\cite{br06}.

Shell structures are shown to change as functions of $N$ and $Z$ consistently with experiments. Some key cases of this shell evolution are discussed, clarifying the effects of central and tensor forces. The validity of the present tensor force is examined in terms of the low-momentum interaction V$_{low k}$ and the Q$_{box}$ formalism.

Abstract. The article is devoted to the analysis of documents from the Central Archive of the Ministry of Defense of the Russian Federation, which allows us to compile a list of names of Soviet soldiers buried in May 1944 on Kommuna Square (Ushakov Square). In total, the names of nine people were identified, including two who were buried in individual graves. Seven people, tankers of the 63rd Taman Tank Brigade, were buried in two mass graves. Presumably, it was the remains of the tankers that were discovered during the reconstruction of the square in 2020.

Spin-glass-like behavior caused by Mn-rich Mn(Ga)As nanoclusters in GaAs

Year: 2009
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We simulate the indirect exchange interaction between Mn-rich Mn(Ga)As nanoclusters in GaAs by analytical means. In contrast to the conventional Ruderman-Kittel-Kasuya-Yosida (RKKY) formula which considers the mediation by the carriers in the medium, we also include the contribution from those inside the clusters. Since the carrier concentration is higher in the clusters, this modification allows the RKKY oscillation to change sign. Consequently, while the previous approach only favors ferromagnetism for this system, an antiferromagnetic coupling is in fact possible. Since the Mn-rich Mn(Ga)As nanoclusters are naturally formed and bound to have different sizes, their spin orientation is likely to be frustrated due to mixed preferences from different neighbors. We argue that this is likely the source of the spin-glass-like behavior which plagues this system. By tuning the size and narrowing its distribution, normal ferromagnetism can be restored with an Curie temperature higher than previously thought.

Long structural zones in the Archaean Yilgarn Craton, Western Australia
Creators: name: Langsford, N
Publisher: name: University Of Tasmania
Year: 2023

description: Eight structural zones from 250km to 800km long, traverse the granite-greenstone terrane of the Eastern Goldfields and Murchison districts of the Yilgam Craton. The structural zones, herein called LSZ, (long structural zones) have been traced using 1 :500,000 geological compilations and AGSO (Australian Geological Survey Organisation) aeromagnetic and gravity data. LSZ are complex linear deformation zones, resulting in the reactivation of structures formed prior to a craton wide shortening episode. Some of the pre-existing structures are interpreted as low angle extensional features, post dating the formation of much of the supracrustals; others as still earlier structures controlling original volcanic and sedimentary greenstone belt architecture. The structural corridors reactivated by the shortening event are overprinted by strikeslip faults which formed relatively narrow shear zones within the corridors. Most of the LSZ contain or abut linear belts of relatively coarse, immature, locally derived elastic sediments, which have been in turn overprinted by shear zones. Carbonate and alkali metasomatism is commonly strongly developed within the local sediment troughs. Numerous alkalic syenitic plugs have been intruded within and adjacent to the LSZ. At I larger scales, several LSZ are associated with K-Th-U rare metal (W-Sn-Be-Li)rich granitoids, or alkali rich syenites in belts up to 250km long. LSZ contain a record of the youngest events related to the evolution of the greenstonegranite terrane; the youngest sediments, the belts of elastics; the youngest shear zones; and the youngest intrusive suites. LSZ are direct hosts to only a few large Yilgarn gold deposits. Several major deposits ¬¨‚àë occur within structures directly connected to LSZ. Although major, deeply penetrating crustal scale structures, LSZ are not a necessary or sufficient condition for the formation of major gold deposits in the Yilgarn.
Housing co-operatives in British Columbia
Creators: name: Constantinu, Marianthi
Publisher: name: University of British Columbia
Year: 2011

description: Housing co-operatives consist basically of people joining together as a corporation to provide housing through group action for themselves. The corporation owns the housing project and each member owns stocks in the corporation which entitles him to live in a unit and share management of the project together with the other members. Housing co-operatives, when supported by adequate education, comprehensive organization and governmental assistance, can provide housing at lower costs than those of equivalent housing in the private market. They are a widely-developed sector of housing in Latin American and European countries. They also exist in the United States Housing, Cooperative |z British Columbiaand various provinces of Canada. Their manifestation in British Columbia is very limited and this constitutes the main concern of this thesis. Such concern focuses on the hypothesis that the formation of housing co-operatives in this province has been retarded by the lack of specific provincial or municipal policies regarding such co-operatives. This hypothesis is supported by various cases, in foreign countries and some Canadian provinces, where legislation for such type of housing caused definite and unprecedented activity in the field. It is thus the conclusion of this thesis that the field of housing co-operatives in British Columbia would develop if specific governmental legislation for such co-operatives were adopted and combined with improvements in education and organization in the field.

description: I recently proposed the "reheating-volume" (RV) prescription as a possible solution to the measure problem in "multiverse" cosmology. The goal of this work is to extend the RV measure to scenarios involving bubble nucleation, such as the string theory landscape. In the spirit of the RV prescription, I propose to calculate the distribution of observable quantities in a landscape that is conditioned in probability to nucleate a finite total number of bubbles to the future of an initial bubble. A general formula for the relative number of bubbles of different types can be derived. I show that the RV measure is well-defined and independent of the choice of the initial bubble type, as long as that type supports further bubble nucleation. Applying the RV measure to a generic landscape, I find that the abundance of Boltzmann brains is always negligibly small compared with the abundance of ordinary observers in the bubbles of the same type. As an illustration, I present explicit results for a toy landscape containing four vacuum states and for landscapes with a single high-energy vacuum and a large number of low-energy vacua.

description: We present high time-resolution multicolour optical observations of the quiescent X-ray transients GRS1124-684 (=GU Mus) and Cen X-4 (=V822 Cen) obtained with ULTRACAM. Superimposed on the secondary stars' ellipsoidal modulation in both objects are large flares on time-scales of 30-60 min, as well as several distinct rapid flares on time-scales of a few minutes, most of which show further variability and unresolved structure. Not significant quasi-periodic oscillations are observed and the power density spectra of GRS1124-684 and Cen X-4 can be described by a power-law. From the colour-colour diagrams of the flare events, for GRS1124-684 we find that the flares can be described by hydrogen gas with a density of N_H~10^24 nucleons cm^-2, a temperature of ~8000 K and arising from a radius of ~0.3 Rsun. Finally we compile the values for the transition radius (the radius of the hot advection-dominated accretion flow) estimated from quasi-periodic oscillations and/or breaks in the power density spectrum for a variety of X-ray transients in different X-ray states. As expected, we find a strong correlation between the bolometric luminosity and the transition radius.

description: Three recent surveys of 21-cm line emission in the Galactic plane, combining single dish and interferometer observations to achieve resolution of 1 arcmin to 2 arcmin, 1 km/s, and good brightness sensitivity, have provided some 650 absorption spectra with corresponding emission spectra for study of the distribution of warm and cool phase H I in the interstellar medium. These emission-absorption spectrum pairs are used to study the temperature of the interstellar neutral hydrogen in the outer disk of the Milky Way, outside the solar circle, to a radius of 25 kpc. The cool neutral medium is distributed in radius and height above the plane with very similar parameters to the warm neutral medium. In particular, the ratio of the emission to the absorption, which gives the mean spin temperature of the gas, stays nearly constant with radius to 25 kpc radius. This suggests that the mixture of cool and warm phases is a robust quantity, and that the changes in the interstellar environment do not force the H I into a regime where there is only one temperature allowed. The mixture of atomic gas phases in the outer disk is roughly 15% to 20% cool (40 K to 60 K), the rest warm, corresponding to mean spin temperature 250 to 400 K. The Galactic warp appears clearly in the absorption data, and other features on the familiar longitude-velocity diagram have analogs in absorption with even higher contrast than for 21-cm emission. In the third and fourth Galactic quadrants the plane is quite flat, in absorption as in emission, in contrast to the strong warp in the first and second quadrants. The scale height of the cool gas is similar to that of the warm gas, and both increase with Galactic radius in the outer disk.

This Fisher matrix based formalism can be used to study the power and aid in the design of future surveys.

Ion fluxes from protoplasts and split segments of oat coleoptiles relating to the mode of action of growth substances
Creators: name: Juswono, Unggul Pundjung
Publisher: name: University Of Tasmania
Year: 2023

description: Indole 3 acetic acid (IAA) is the major plant growth substance that causes normal plant elongation and the bending responses to light and gravity. The mechanism by which IAA causes cell wall loosening to produce elongation growth of plant stems is still in controversy. The most accepted hypothesis for the mode of action of IAA is the acid growth hypothesis, which states that auxin regulates wall loosening by causing a pH drop in the cell wall. Many questions are left in relation to the involvement of ions in the mechanism of wall loosening. The investigation of ion fluxes from plant cells in the presence and absence of the cell walls may contribute to the explanationof the involvement of these ions. The study of proton fluxes on opposite sides of protoplasts shows an asymmetric pattern and polarity of the flux. This leads to the conclusion that the protoplasts must have polarity to allow pH regulation in the cytoplasm. Estimation of the change in the cytoplasmic pH due to observed influx or efflux of protons shows that the cytoplasmic buffering capacity alone is not capable of neutralising the observed proton flux. IAA and fusicoccin (FC) stimulate proton extrusion from protoplasts by factors of about three and two times the control. It must be stimulation of active proton transport that is caused by these substances. IAA also enhances the calcium efflux which may be a way to maintain the cytoplasmic free calcium at a low level. As with protoplasts, IAA and FC also enhance proton and calcium effluxes from epidermal and parenchymal cells of split oat coleoptiles. Ion fluxes from the epidermal cells are larger than those from the parenchymal cells. It could be that the epidermal cells are more sensitive to the growth substances. However, the effects of IAA and FC on ion fluxes from the parenchymal cells are still observable. There is no time delay in enhancement of proton and calcium fluxes from protoplasts and segments by IAA and FC. This is in contrast with results of other workers in observing the effect of IAA. However, enhancement of proton and calcium fluxes by FC is larger than for IAA. The calcium appearing in the external medium may come from a compartment inside the cell and from the cell wall. The cell walls contribute about 75 to 90 % of the total amount of the emerging calcium. The calcium from the walls results from the exchange of the extruded protons from inside the cell with the condensed calcium in the wall. This is in agreement with the Weak Acid Donnan Manning (WADM) model for cell wall ion exchange.

Interiors from the mind : pictorial illusionism within painting
Creators: name: Dewhurst, Andrew
Publisher: name: University Of Tasmania
Year: 2023

description: This project sets out to investigate spatial illusion within realist painting. Observations concerning speculative architectural constructs as a pictorial space provides the content for the project. This research develops visual strategies with the intention of enhancing the viewers' perceptual experience of an illusionary space. The aim of this project has been to push beyond traditions of illusory pictorial spaces that have informed the research. To extend those representations, a series of methodologies were developed that fuse both the virtual architectural space of digital imaging with the pictorial illusionism of painting that reflects the techniques formulated by early fifteenth century Flemish painters. The paintings are constructed from multiple digitally captured photographs of interior architecture, reconstructed into fictional spaces through digital manipulation. The spaces feature multiple entry/exit points that are ambiguous and devoid of human presence. Extraneous details are removed from the sourced imagery and the resulting spaces are vast, labyrinthine, artificially lit passageways. Central to the project is the duplicity apparent in mirrors and reflections. These are employed as devices to lead the viewer to speculate and contemplate the ambiguities within the painting. The outcome is a group of paintings submitted for examination; the exhibition contains the original discourse of the project. The exegesis chronicles the practical and conceptual inquiries, together with an exploration of the issues significant to the project, placed in context through discussions of historical and contemporary practice.
The theme of violence in the later fiction of Herman Melville
Creators: name: McKeown, Thomas Wilson
Publisher: name: University of British Columbia
Year: 2011

description: Incidents of violence abound in most of the novels and short stories of Herman Melville, and in several of them, especially Billy Budd, the protagonist is characterized in terms of his attitude towards violence. The central contention of my thesis is that in the development of Melville's fiction from Moby-Dick to Billy Budd the thematic role of violence changes from that of a destructive to a more redemptive force. This change parallels another change that takes place in his fiction, from a focus on the individual who is destroyed by his commitment to violence, to the society which is temporarily purged of evil through the violent act of an individual. In my first two chapters I discuss Moby-Dick and Pierre as representing Melville's early attitude to violence. In Moby-Dick violence is associated primarily with Ahab, whose characterization takes up about half of the novel. In Pierre violence becomes a more central motif, simply because Pierre is the only major character in the novel, and consequently his involvement with violence reflects the focus of the novel as a whole. Both of these novels employ the theme of violence mainly to dramatize the separation of the self from society. In chapters three and four I discuss the ways in which "Bartleby the Scrivener" and "Benito Cereno" prefigure the role of violence in Billy Budd. The fact that even, the timid lawyer is capable of feeling the faint stirrings of anger within him anticipates the concern of Billy Budd with the universality of human emotion, and its important role in helping to redeem an excessively rationalistic society. “Benito Cereno" also looks toward Billy Budd, in that Cereno's magnanimous concern for Delano's safety, which gives him the strength to break away from Babo's influence and jump into the boat, prefigures Billy's magnaminity at his execution. In my final chapter I discuss the way in which the destructive violence and a focus on the fate of the individual in Moby-Dick has been replaced by the socially redemptive violence and a focus on the fate of society in Billy Budd. Melville's development in this respect may be measured by his transformation of murder into a socially desirable act. Billy destroys evil and is in turn destroyed by the society which he protects, yet his influence lives in the hearts of the sailors who have known him.

description: We report on the properties of 89 low mass star clusters located in the vicinity of luminous young clusters (blue globulars) in the disk of M31. 82 of the clusters are newly detected. We have determined their integrated magnitudes and colors, based on a series of Hubble Space Telescope Wide Field/Planetary Camera 2 exposures in blue and red (HST filters F450W and F814W). The integrated apparent magnitudes range from F450W = 17.5 to 22.5, and the colors indicate a wide range of ages. Stellar color-magnitude diagrams for all clusters were obtained and those with bright enough stars were fit to theoretical isochrones to provide age estimates. The ages range from 12 Myr to >500 Myr. Reddenings, which average E(F450 - F814) = 0.59 with a dispersion of 0.21 magnitudes, were derived from the main sequence fitting for those clusters. Comparison of these ages and integrated colors with single population theoretical models with solar abundances suggests a color offset of 0.085 magnitudes at the ages tested. Estimated ages for the remaining clusters are based on their measured colors. The age-frequency diagram shows a steep decline of number with age, with a large decrease in number per age interval between the youngest and the oldest clusters detected.

description: We extended existing theory of the two-pulse electric-dipole echo in glasses in a magnetic field to the three-pulse echo. As is well known, at low temperatures two-level systems (TLS's) are responsible for the echo phenomenon in glasses. Using a diagram technique in the framework of perturbation theory we derived a simple formula for the three-pulse echo amplitude. As in the case of two-pulse echo the magnetic field dependence of the tree-pulse echo amplitude in glasses is related to quadrupole electric moments of TLS's non-spherical nuclei and/or dipole-dipole interaction of their nuclear spins. These two mechanisms are responsible for the fine level splitting of TLS. As a result TLS transforms to multi-level system with the fine level splitting depending on a magnetic field. Due to existence in the theory the additional parameter T - the time interval between the second and the third pulses we have more reach spectrum of echo oscillations in a magnetic field in comparison with the case of the two-pulse echo.

Box-and-whisker plots show high, low, and median values, with lower and upper edges of each box denoting first and third quartiles, respectively. Plots of the same color represent results from replicate plates (or trays) using larvae derived from independent cohorts of eggs. No significant differences between replicates were detected for adult females (NS). Size likewise did not differ between treatments for adult females (NS; Mann–Whitney U test, p > 0.05) after pooling replicates, while gnotobiotic adult males were marginally smaller than conventional males even after accounting for variation between replicates (*; Mann–Whitney U test, p

description: We present highlights from a series of four simultaneous Suzaku/RXTE observations of the black hole candidate Cyg X-1. We briefly summarize several key results from our decade long RXTE monitoring campaign. We then comment on challenges of analyzing the Suzaku data, i.e., improving the aspect correction beyond that of the existing tools, and quantitatively assessing pileup. All of our Suzaku observations (one, by design) occurred at or very near orbital phase 0 (superior conjunction), and hence show evolution in color-color diagrams due to X-ray absorption by material from the wind of the secondary. We present simple partial absorption models for this evolution. We then compare the Suzaku and RXTE data, and explicitly divide the Fe line region into narrow and broad components. Both are required for the Suzaku data, and are seen to be consistent with the RXTE data. These Suzaku observations occurred near historically hard, low flux states. We present fits of the broad band spectra with a simple phenomenological broken powerlaw model, as well as a more physically motivated Comptonization model. Whereas the former class of models described nearly all of the RXTE campaign better than any physical model, here the latter model is slightly more successful. The Comptonization model, however, exhibits little evidence for a soft disk component, which formally corresponds to a small, inner disk radius. Whether this is physical, due to unmodeled absorption, or is a calibration issue, remains an open question.

Chiral Dynamics Predictions for $η'\toηππ$

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study the decay $η'\toηππ$ in two different chiral invariant approaches: Large-$N_c$ Chiral Perturbation Theory (ChPT) and Large-$N_c$ Resonance Chiral Theory (RChT). We analyze the Dalitz plot and the invariant mass spectra. We also compare the relevance of the isoscalar and isovector channels in these approaches. While the predictions of Large-$N_c$ ChPT at next-to-leading order slightly disagree with the measured decay width (showing the need for final state interactions and higher order local contributions), a reasonable agreement is obtained for the case of RChT. Forthcoming experimental analyses at Bonn, Frascati, Jülich and Mainz will decide among the different frameworks.

Spatial and temporal variation in growth and age composition of the temperate wrasse Notolabrus fucicola in Tasmanian waters
Creators: name: Ewing, Graeme
Publisher: name: University Of Tasmania
Year: 2023

description: The mechanisms that determine the age and size structure of a population are not well understood for temperate reef species and are functionally divided into pre-settlement and post-settlement processes. Their relative importance in structuring populations can be inferred from spatial comparisons of adult age composition and growth rates, provided factors that obscure or bias the ability to detect signals from early life history are considered. These factors include migration, fishing mortality and methodological issues such as ageing errors and size-selectivity of sampling gears. The biological features that promote Notolabrus fucicola as a suitable species for demographic research and the highly variable hydrology of the east and southeast coasts of Tasmania, provide an opportunity for examination of the relative roles of pre-and post-recruitment processes in structuring temperate reef populations. In addition, N. fucicola is the primary target of a commercial live wrasse fishery that has developed over the last decade in Tasmania, necessitating an understanding of its population dynamics for effective management. Notolabrus fucicola were collected using baited traps from six locations around the east and southeast coasts of Tasmania. A methodology for age estimation was developed using thinly sliced transverse sagittal otolith sections and the periodicity and timing of increment formation, location of the first annual increment and precision of age estimations were validated. A size-selectivity function for the traps was calculated directly from sampling an isolated population of N. fucicola of known size structure, generated from a simulated fish-down using tags. The selectivity function was used to reconstruct the raw size and age structures from which fishing mortality was estimated. Fishing mortality varied spatially, with strong mortality prior to the minimum legal size limit implied at some sites. Spatial comparisons of growth were not biased by fishing mortality and indicated that growth rates followed the sea surface temperature gradient, but did not follow trends in fishing mortality, diet or reef structure. Given that growth is sensitive to resource limitation, the spatial trend in growth rates suggested that populations of N. fucicola were not structured by post-settlement density-dependent mortality. Spatial and temporal comparisons of selectivity-corrected age compositions, whilst primarily detecting differences in the level of fishing mortality between sites, indicated low variation in relative year class strength. This result is consistent with recent findings suggesting that N. fucicola are well adapted to maximize larval survival despite the highly variable coastal hydrography. Thus, it is likely that populations of the temperate wrasse N. fucicola are primarily structured by larval supply.
Long-Term Evolution of and X-ray Emission from a Recoiling Supermassive Black Hole in a Disk Galaxy

description: Recent numerical relativity simulations have shown that the emission of gravitational waves at the merger of two black holes gives a recoil kick to the final black hole. We follow the orbits of a recoiling supermassive black hole (SMBH) in a fixed background potential of a disk galaxy including the effect of dynamical friction. If the recoil velocity of the SMBH is smaller than the escape velocity of the galaxy, the SMBH moves around in the potential along a complex trajectory before it spirals into the galactic center through dynamical friction. We consider the accretion of gas onto the SMBH from the surrounding ISM and estimate the X-ray luminosity of the SMBH. We find that it can be larger than 3x 10^39 erg^-1 or the typical X-ray luminosity of ultra-luminous X-ray sources, when the SMBH passes the galactic disk. In particular, the luminosity could exceed ~10^46 erg s^-1, if the SMBH is ejected into the galactic disk. The average luminosity gradually increases as the SMBH spirals into the galactic center. We also estimate the probability of finding recoiling SMBHs with X-ray luminosities of >3x 10^39 erg^-1 in a disk galaxy.

Micropropagation and horticultural potential of native Tasmanian Liliaceae and Iridaceae
Creators: name: Gilmour, DD
Publisher: name: University Of Tasmania

description: A study encompassing a range of botanical research areas was undertaken to determine the horticultural potential of some members of the native Tasmanian Liliaceae and Iridaceae. Six main species were studied: Blandfordia punicea, Dianella tasmanica and Milligania densiflora from the Liliaceae as well as Diplarrena moraea, Diplarrena latifolia and Isophysis tasmanica from the Iridaceae. With the exception of D. tasmanica and D. moraea, all species are endemic to Tasmania. Seed germination trials were carried out to assess the viability of this method of propagation. The natural germination percentages were extremely high for B. punicea (93-100%), D. moraea (97%) and I. tasmanica (90-100%) and reasonably high for D. latifolia (76%). For D. tasmanica and M. densiflora they were much lower (38% and 48%, respectively). The germination percentage of M. densiflora could be increased to 88% simply by germinating the seed in vitro; it could be increased further to 90% by disinfesting seeds for 35 min and growing them on a 1/2 MS medium. However, for D. tasmanica there are dormancy mechanisms present which proved more difficult to overcome. The most promising methods for this species were smoke treatments and partial removal of the testa. The percentage of seeds germinating increased with increasing smoke extract concentration; however, 100% smoke inhibited germination. Removal of part of the testa and growth in vitro was the best treatment, with 90% germination achieved. In vitro propagation was achieved for all species studied. Successful protocols were devised for disinfestation, shoot initiation and multiplication, rooting and transplanting to ex vitro conditions. Not all explant types investigated were suitable for all species, with the major problem being contamination. Meristematic regions originating underground were more difficult to disinfest than the immature floral explant types that originated above-ground. In general, a MS or 1/2 MS medium was suitable for growth of all species studied and BAP (at 8-32¬¨¬µM) was generally successful for shoot multiplication. Roots often grew on shoots on multiplication media, or could be induced to form on a medium containing NAA (or less successfully, IAA or IBA) or by placing them on a medium free of plant growth regulators. Transplanting was successful for all species, with a high percentage of plantlets surviving. However, they were susceptible to damping off if too much water was applied. Experiments were also performed to examine the possibility of forcing D. tasmanica plants to flower out-of-season. By manipulation of temperature and photoperiod plants could be forced to flower earlier. The fire-related treatments of smoke and foliage removal also increased the percentage of flowering plants compared to the control.
