Demographic Feedback Between Clonal Growth And Fragmentation In An Invasive Seaweed, Jeffrey T. Wright, Andrew R. Davis
Demographic Feedback Between Clonal Growth And Fragmentation In An Invasive Seaweed, Jeffrey T. Wright, Andrew R. Davis
Faculty of Science - Papers (Archive)
Many abundant plants, invertebrates, and seaweed are clonal, and this allows the formation of high-density aggregations, foraging, and the placement of modules into new space, and rapid rates of expansion. For these species, population density and rates of expansion are functions of recruitment of asexual modules and post-recruitment vegetative growth and survivorship. In this study, we provide the first experimental test of the relative importance of these two processes in determining the abundance of a clonal seaweed using Caulerpa taxifolia, an invasive green alga that spreads rapidly and reaches very high abundance. We asked two main questions: What is …

Two new platinum complexes, trans-chlorodiammine[N-(2-aminoethyl)-4-[4-(N-methylimidazole-2-carboxamido)-N-methylpyrrole-2-carboxamido]-N-methylpyrrole-2-carboxamide]platinum(II) chloride (DJ1953-2) and trans-chlorodiammine[N-(6-aminohexyl)-4-[4-(N-methylimidazole-2-carboxamido)-N-methylpyrrole-2-carboxamido]-N-methylpyrrole-2-carboxamide]platinum(II) chloride (DJ1953-6) have been synthesized as proof-of-concept molecules in the design of agents that can specifically target genes in DNA. Coordinate covalent binding to DNA was demonstrated with electrospray ionization mass spectrometry. Using circular dichroism, these complexes were found to show greater DNA binding affinity to the target sequence: d(CATTGTCAGAC)2, than toward either d(GTCTGTCAATG)2, which contains different flanking sequences, or d(CATTGAGAGAC)2, which contains a double base pair mismatch sequence. DJ1953-2 unwinds the DNA helix by around 13°, but neither metal complex significantly affects the DNA melting temperature. Unlike simple DNA minor …

There have been few studies on the structure and dynamics of sponge-dominated assemblages, despite the fact that such assemblages are vulnerable to environmental impacts from many anthropogenic disturbances. Sponges are generally slow to recruit, slow growing and long lived; hence, they may be very vulnerable to anthropogenic and natural disturbances. In order to understand how such assemblages may respond to disturbance, it is essential to measure natural patterns of spatial differences and temporal changes, so that any future impact assessments can be identified. This study quantified and contrasted patterns of abundance in sponge-dominated assemblages on deep reefs (18 to 20 …

The Geomorphological Evolution Of A Wave-Dominated Barrier Estuary: Burrill Lake, New South Wales, Australia, Brian G. Jones, Craig R. Sloss, David M. Price, C.E. Mcclennen, John De Carli

The geomorphological evolution of the Holocene wave-dominated barrier estuary at Burrill Lake on the New South Wales coast, Australia, has been delineated using a combination of seismic stratigraphy and the lithostratigraphic analysis of vibracores collected from the back-barrier estuarine environment. A combination of radiocarbon and aspartic acid racemisation-derived ages obtained on Holocene fossil molluscs, and the thermoluminescent signal in remnant Last Interglacial barrier sediments provides the chronological framework for this investigation. Results from this paper show that the barrier estuary occupies a relatively narrow (<1.5 km wide) and shallow (<40 m deep) incised bedrock valley formed during sea-level lowstands. Late Pleistocene sedimentary successions and remnants of the Last Interglacial barrier have been preserved within the incised valley axis and the mouth of the incised valley. These sediments, deposited during the Last Interglacial sea-level highstand, have subsequently been partially removed during the last glacial maximum. Overlying the antecedent late Pleistocene landsurface is a near basin-wide basal marine sand deposited in response to rising sea level associated with the most recent post-glacial marine transgression, which inundated the shallow incised valley ca.7800 years ago. More open marine conditions, with a diverse assemblage of estuarine and marine mollusc species, persisted until ca. 4500 years ago when the stabilizing Holocene barrier resulted in the development of a lowenergy back-barrier lagoonal environment. A late Holocene 1-2 m regression of sea level ca. 3000 years ago further restricted oceanic circulation, increased the rate of fluvial bay-head delta progradation and the extension of the backbarrier central basin mud facies. This evolutionary model of barrier estuary evolution developed for Burrill Lake is consistent with recent research conducted in Lake Illawarra and St Georges Basin and can be applied to other estuaries that have formed in relatively shallow and narrow incised bedrock valleys on tectonically stable, wave-dominated coastlines.

Faculty of Science - Papers (Archive)
For marine invertebrates such as corals, restricted dispersal of sperm and/or larvae have been invoked to explain large heterozygote deficits and population subdivision apparent in many genetic surveys. Equally though, for the many corals and other invertebrates that are hermaphroditic, inbreeding through self-fertilisation may also account for heterozygote deficits. Flexibility of mating systems to allow at least some level of self-fertilisation may be favoured by selection, as this would facilitate the founding of new populations by low numbers or densities of colonists. While tests for self-compatibility are relatively easy for broadcast-spawning corals, experimentally determining the level of selfing in corals …

The infrared spectrum of mass selected Li +-D 2 cations is recorded in the D-D stretch region (2860-2950 cm -1) in a tandem mass spectrometer by monitoring Li + photofragments. The D-D stretch vibration of Li +-D 2 is shifted by -79 cm -1 from that of the free D 2 molecule indicating that the vibrational excitation of the D 2 subunit strengthens the effective Li +-D 2 intermolecular interaction. Around 100 rovibrational transitions, belonging to parallel K a=0-0, 1-1, and 2-2 subbands, are fitted to a Watson A-reduced Hamiltonian to yield effective molecular parameters. The infrared spectrum shows that …

Coastal waters adjacent to industrialised catchments are likely to receive contaminants from urban run-off, storm water drains, and industrial effluent discharges. While routine monitoring may indicate that contaminant concentrations are below levels of regulatory concern, there is generally a poor understanding of the rate, concentration and consistency of contaminant inputs and the associated biological effects.

Faculty of Science - Papers (Archive)
Assessment of contaminated sediments and development of remediation strategies is becoming an important priority for regulators and industries worldwide. Although sediment quality assessment frameworks exist, poor scientific procedures and a limited understanding of species sensitivity to common contaminants hinders most assessment programs. Globally, sediment quality guidelines (SQGs) for metals vary over several orders of magnitude and are not based on clear cause-effect relationships. Although equilibrium partitioning approaches to developing SQGs have been attempted, the cause-effect relationships are weak due to the many other modifying factors that influence metal bioavailability and toxicity. The inherent lack of defensible SQGs for metals currently …

Are Seed Dispersal And Predation In Fire-Sensitive Persoonia Species (Proteacae) Associated With Rarity?, Paul Rymer
Faculty of Science - Papers (Archive)
Seed dispersal and predation are key processes affecting the colonization and extinction of populations in fire-prone environments. If these processes influence distribution and abundance, rare species may be expected to have less seed removal and/or greater seed predation than common congeners. I compared seed removal and predation under plants in two closely related pairs of fire-sensitive common and rare Persoonia species with fleshy fruits in two replicate populations of each species. Seed removal by macropods was significantly greater in the two common species (>50% seeds/plant) than in their rare congeners (<25%). There was no overall effect of rarity on seed predation by rodents, but there were significantly more seeds of the rare Persoonia mollis subspecies maxima eaten than of the other three species. Plant size was the only attribute measured that was significantly correlated with seed removal (r ¼ 0:50). After including plant size as a covariate in the analysis, I still detected a significant effect of rarity on seed removal. High levels of seed removal were sustained in both small and large populations of the common Persoonia lanceolata, suggesting that population size may not be contributing to the differences between these common and rare species. The common-rare difference in the seed removal of Persoonia species seems robust across several plant and population attributes.

Virtually all the known physico-chemical and biological techniques have been explored for treatment of extremely recalcitrant dye wastewater; none, however, has emerged as a panacea. A single universally applicable end-of-pipe solution appears to be unrealistic, and combination of appropriate techniques is deemed imperative to devise technically and economically feasible options. An in-depth evaluation of wide range of potential hybrid technologies delineated in literature along with plausible analyses of available cost information has been furnished. In addition to underscoring the indispensability of hybrid technologies, this paper also endorses the inclusion of energy and water reuse plan within the treatment scheme, and …

A submerged microfiltration membrane bioreactor implementing the white-rot fungus Coriolus versicolor was developed for the treatment of textile dye wastewater following explorations with different fouling-prevention techniques. The optimum combination ensuring permeate quality and precluding membrane fouling comprises of placing a bundle of hollow fibers within a non-woven coarse-pore (50–200 μm) mesh cage, so as to avoid direct deposition of sludge onto it, together with arrangements for its periodic high-pressure back-washing (3 s/10 min) and chemical back-flushing (100 ml/m2, every third day). Under controlled temperature (29±1°C) and pH (4.5±0.2), and applied HRT and an average flux of 15 h and 0.021 …

A submerged microfiltration membrane bioreactor implementing the white-rot fungus Coriolus versicolor was developed for effective treatment of textile dye wastewater [1]. In that system membrane fouling was precluded by placing a bundle of hollow fibers within a pre-filtration assembly, so as to avoid direct deposition of sludge onto it, together with its periodic high-pressure back-washing and low-dose chemical back-flushing. However, the extreme vulnerability of the bare membrane used in that study to inter-fibral deposition of sludge leading to merging of fibers indicated necessity of development of an appropriate module so that the proposed system may enjoy more flexibility in terms …

Column-averaged volume mixing ratios of CH4 were retrieved with a precision of better than 0.5% from infrared solar absorption spectra obtained at Ny-Alesund (Spitsbergen, 79°N) between 1997 and 2004 and during two ship cruises (54°N–34°S) on the Atlantic in 2003. The retrieval has been performed in a spectral region available to all operational FTIR (Fourier Transform InfraRed) spectrometers performing solar absorption measurements. The seasonality and the long-term increase of the tropospheric volume-mixing ratio, derived from the infrared measurements agree well with data from surface sampling at this site. The latitudinal variation of ship-borne measurements between 54°N and 34°S is in …

While exceedingly rare on any given archaeological site, engraved stone artefacts have nonetheless been reported from sites covering a range of periods mid regions across the world. Attempts to interpret such engravings have often focused on potential representational or communicative functions, including their role in notational systems, symbolic depiction, and the development of early forms of writing. Contextual and microscopic investigation Of a number of engraved artefacts discovered in a large assemblage of dolerite artefacts excavated from a Neolithic hilltop habitation and stone-tool production site in south India suggests, however, that an alternative interpretation of engraved stone artefacts is possible. …

Gay And Lesbian Identity Work At Home, Andrew W. Gorman-Murray
Faculty of Science - Papers (Archive)
Geographical and sociological literature on gay/lesbian experiences of domestic environments has drawn attention to the heteronormativity of homes, focusing on how these sites often marginalise and silence gay/lesbian identities. While not denying these arguments, I suggest that many gay men and lesbians have also used domestic spaces to resist heteronormative socialisation and affirm gay/lesbian identities. In this paper I explore some of these affirmative uses. Drawing on 37 in-depth interviews with gay/lesbian Australians, I examine two key ways that some gay men and lesbians have used homes to consolidate their sexual identities: (i) the role played by domestic spaces in …

Serum opacity factor (SOF) is a bifunctional cell surface protein expressed by 40-50% of group A streptococcal (GAS) strains comprised of a C-terminal domain that binds fibronectin and an N-terminal domain that mediates opacification of mammalian sera. The sof gene was recently discovered to be co-transcribed in a two-gene operon with a gene encoding another fibronectin-binding protein, sfbX. We compared the ability of a SOF(+) wild-type (WT) serotype M49 GAS strain and isogenic mutants lacking SOF or SfbX to invade cultured HEp-2 human pharyngeal epithelial cells. Elimination of SOF led to a significant decrease in HEp-2 intracellular invasion while loss …

Mycoplasma hyopneumoniae is the causative agent of porcine enzootic pneumonia, a chronic and economically significant respiratory disease that affects swine production worldwide. M. hyopneumoniae adheres to, and adversely affects the function of ciliated epithelial cells of the respiratory tract, and the cilium adhesin (P97), is intricately but not exclusively involved in this process. Although binding of pathogenic bacteria to glycosaminoglycans is a recognised step in pathogenesis, knowledge of glycosaminoglycan-binding proteins is lacking in M. hyopneumoniae. However, heparin and other sulfated polysaccharides are known to block the binding of M. hyopneumoniae to purified swine respiratory cilia. In this study, four regions …

This paper reviews approaches to assessing vulnerability of coasts to climate change and gives details of one of the approaches, coastal vulnerability index (CVI). The CVI ranks the following in terms of their physical contribution to sea-level rise-related coastal change: dune height, barrier type, beach type, relative sea-level change, shoreline erosion and accretion, mean tidal range and mean wave height. These variables are seen to be more useful to the Australian coast. The ranking for each input variable were combined and an index value calculated for selected beaches on the Illawarra and Batemans Bay coasts. The results are presented here.
