Pyrite framboids interpreted as microbial colonies within the Permian Zoophycos spreiten from southeastern Australia

Two types of pyrite framboids (PF, probably sulphate-reducing bacteria) have been found
within the Zoophycos spreiten, hosted in the Guadalupian (Middle Permian) glaciomarine greywacke
of the Westley Park Sandstone Member within the Broughton Formation from the southern Sydney
Basin of southeastern Australia. They are composed of non-sheathed (PF1) and sheathed (PF2)
sub-micron balls, respectively. Chemically, the sub-micron balls consist of iron, sulphur, carbon and
oxygen. Both PF1 and PF2 occur in rhythmic alternationwithin the thick, light-grey and thin, dark-grey
minor lamellae of Zoophycos spreiten. The framboids from the minor lamellae are highly abundant and
occur in an orderly arrangement of equal density and in a good state of preservation.Within Zoophycos
spreiten no homogeneous filling, fecal pellets, or any sign of re-exploitation of the minor lamellae have
been recognized. No similar framboids have been observed outside Zoophycos spreiten. Therefore, the
framboids are interpreted as the pyritized remains of microbial colonies within Zoophycos spreiten.
The trace Zoophycos would be a multifunctional garden thatmay have been carefully constructed by the
Zoophycos maker, where different microbial colonies were orderly and carefully planted and cultured
within different minor lamellae. Further, it is proposed that the Zoophycos maker had a symbiotic
relationship with microbial colonies on the mutual basis of food supply and redox conditions. The fact
that the overlying spreiten cut the underlying ones indicates that the Zoophycos from the study area is
of an upward construction. The rhythmic alternation of both the thick, light-grey and thin, dark-grey
minor lamellae within Zoophycos spreiten may be suggestive of a gardening manner of the Zoophycos
maker responding to the warm and cold changes, food supply in pulses and variations of sedimentation
rate for planting and culturing microbial colonies under the conditions of a glaciomarine environment
at the high latitudes.

Contrasting genetic structuring between colonies of the world's smallest penguin, Eudyptula minor (Aves: Spheniscidae)

The Little Penguin, Eudyptula minor, is a seabird that nests in colonies throughout New Zealand and southern Australia. Individuals from different colonies in southeast Australia differ significantly in morphology and ecology, suggesting that some genetic structuring may exist among colonies. In contrast, the marking of individuals with flipper bands has revealed some, albeit infrequent, movement between colonies. To determine the extent of genetic structuring, we tested the null hypothesis of substantial gene flow within southeast Australia by examining patterns of genetic variation across seven colonies separated by up to 1,500 km. Phylogeographic structuring was absent for mitochondrial control region sequences (2–3 individuals per colony). Microsatellite allele frequencies at five loci and mitochondrial haplotype frequencies (50 individuals per colony) were also homogenous among the majority of colonies sampled, although two colonies at the western periphery of the sampling range were distinct from those to the east. The genetic homogeneity among the majority of colonies can be explained by low but consistent contemporary gene flow among them, or a recent founder event in Bass Strait following the last marine transgression. The genetic break towards the western end of the sampling distribution appears best explained by differences in sea surface temperature and, consequentially breeding phenology, the latter hindering genetically effective migration.

Music in state-supported schooling in South Australia to 1920

This thesis is a study of the establishment of the music curriculum in state-supported schools in South Australia from the beginnings of such schooling until 1920. There will be a discussion of issues to be explored and the method by which this investigation will proceed. A literature survey of relevant research will be included, after which there will be a sketch of the development of state-supported schooling in South Australia. Several broad themes have been chosen as the means of organising the historical material: the rationales offered for the inclusion of music in schooling, the methodologies, syllabi and materials of such music instruction, the provisions for teacher training in music, both preservice and as professional development for established teachers, and the place and function of music in schooling. Each of these themes will form the framework for a chronological narrative. Comparisons will be made with three neighbouring colonies/States concerning each of these themes and conclusions will be drawn. Finally, overall conclusions will be made concerning the initial contentions raised in this chapter in the light of the data presented. Although this study is principally concerned with the establishment of music in state-supported schooling, there will be a brief consideration of the colony of South Australia from its proclamation in 1836. The music pedagogical context that prevailed at that time will be discussed and this will, of necessity, include developments that occurred before 1836. The period under consideration will close in 1920, by which time the music curriculum for South Australia was established, and the second of the influential figures in music education was at his zenith. At this time there was a new school curriculum in place which remained essentially unchanged for several decades. As well as the broad themes identified, this thesis will investigate several contentions as it attempts to chronicle and interpret the establishment and development of music in state-supported schooling in South Australia up to 1920. The first contention of this thesis is that music in state-supported schooling, once established, did not change significantly from its inception throughout the period under consideration. In seeking a discussion of the existence and importance of the notion of an absence of change or stasis, the theory of punctuated equilibria, which identifies stasis as the norm in the evolutionary growth of species, will be employed as an insightful analogy. It should be recognised that stasis exists, should be expected and may well be the prevailing norm. The second contention of this thesis is that advocates were and continue to be crucial to the establishment and continued existence of music in state-supported schooling. For change to occur there must be pressure through such agencies as motivated individuals holding positions of authority, and thus able to influence the educational system and its provisions. The pedagogical method introduced into an educational system is often that espoused by the acknowledged advocate. During the period under consideration there were two significant advocates for music in state-supported schools. The third contention of this thesis is that music was used in South Australia, as in the other colonies/States, as an agent of social reform, through the selection of repertoire and the way in which music was employed in state-supported schooling. Music was considered inherently uplifting. During the nineteenth and early twentieth centuries, the music selected for school singing carried texts with messages deemed significant by those who controlled the education system. The repertoire was not that of the receiving class but came from a middle class tradition of fully notated art music in which correct performance and notational reading were emphasised. A sweet, pure vocal tone was desired, as strident, harsh, speaking tones were perceived as a symptom of incipient larrikinism which was not desired in schooling. Music was seen as a contributor to good order and discipline in schooling.

The sermon in the British colonies

This article discusses sermons in the British colonies. It draws on existing studies to identify key themes and areas of investigation that may be fruitful for further study. It considers examples from the North American colonies, from 1688 until independence, and from India in the eighteenth and nineteenth centuries and the Cape Colony in the nineteenth century. It then presents a case study of the sermon in early colonial Australia.

The descent of Morgan in Australia: kinship representation from the Australian colonies

Morgan had two extraordinary disciples in Lorimer Fison and Alfred Howitt in Australia. They were inspired by Morgan’s kinship schedule and were profoundly engaged in the method and theory of the collection of kinship data and its interpretation. Fison began using the schedule in Fiji in 1869. Soon after his first contact with Howitt, in 1873, they changed the method of collection of kinship terminologies. This paper traces the shift from tabulated kinship lists to family trees and the use of sticks to represent relationships (nearly twenty years before Rivers’ celebrated ‘genealogical method’), as well as efforts to find new means of representing kinship through experimentation with ‘ graphic formulae’ inspired by chemical equations. These innovations first occurred through the gathering of kinship data about the Kŭnai of Gippsland, Victoria, and crucially involved close collaboration between Howitt and his Kŭnai consultant Tulaba. What was revealed in this process was an indigenous kinship system quite different from that found in other parts of colonial Australia known at the time. Fison and Howitt explained this system as transitional between two stages in terms of Morgan’s evolutionary scheme, but at the same time challenged the assumption that the general scheme could be applied to Australia. While the details of Morgan’s evolutionary stages have faded from view, the methods of collection, representation, transmission, comparison and interpretation of kinship data are still live issues in anthropology today. The kind of kinship system discovered in Gippsland involved neutralisation of the cross-parallel distinctions, distinctions that are otherwise typical of Australia. Such neutralisation can now be shown to occur elsewhere in Australia. There does indeed seem to have been a transition from a Dravidianate system with cross-parallel distinctions to ‘overlays’ of cross-parallel neutralisation, and finally a complete loss in some generations of such distinctions in the terminology. These discoveries open up possibilities of rebuilding a diachronic theory of kinship change and evolution, incorporating some of the insights of Fison and Howitt, though without their specific hypotheses, either of local developments in Gippsland or the grand scheme of Morgan.

‘The freedom suits me’: encouraging girls to settle in the colonies

This chapter examines the role of the immensely popular Girl's Own Paper to demonstrate how girls were prompted to think of emigration to a British colony.

Corvids congregate to breeding colonies of a burrow-nesting seabird

Egg predation is a major cause of reproductive failure among birds, and can compromise the viability of affected populations. Some egg predators aggregate near colonially breeding birds to exploit the seasonal increase of prey resources. We investigated spatial and temporal variations in the abundance of an egg predator (little raven Corvus mellori; Corvidae) to identify whether ravens aggregate spatially or temporally to coincide with any of three potential prey species: burrow-nesting little penguin (Eudyptula minor; Spheniscidae), short-tailed shearwater (Ardenna tenuirostris; Procellariidae), and surface-nesting silver gull (Chroicocephalus novaehollandiae; Laridae). We derived spatially explicit density estimates of little ravens using distance sampling along line transects throughout a calendar year, which encompassed little penguin, short-tailed shearwater and silver gull breeding and non-breeding seasons. High raven abundance coincided temporally with penguin and gull egg laying periods but not with that of shearwaters. The spatial distribution of raven density corresponded with the little penguin colony but not with shearwater or gull colonies. Thus, the presence of little penguin eggs in burrows correlated strongly with little raven activity, and this implies that little ravens may have learnt to exploit the plentiful subsurface food resource of little penguin eggs. Corvid management may be required to maintain the viability of this socially and economically important penguin colony.

Activity and flight trajectory monitoring of mosquito colonies for butomated behaviour analysis

Monitoring and tracking of mosquitoes using image processing is important to facilitate the mosquitos’ behaviour analysis automatically over longer period of times. In this paper, we propose a simple methodology to monitor mosquitos’ activity using multiple cameras optimally placed. In order to ensure optimal camera coverage for the area of observation and desired image quality; we propose to simulate the experimental setup in a 3D virtual environment to obtain one-off optimum camera placement parameters. Our proposed methodology is demonstrated to have improved the activity monitoring process using two cameras for accurate count of occluded mosquitoes and 3D trajectory path reconstruction. This framework will enable working out more challenging tasks of constructing 3D trajectories using information received from multiple low quality cameras, which provide inconsistent and discontinuous trajectories.
