Home range and habitat use by the roadside hawk, Rupornis magnirostris (Gmelin, 1788) (Aves: Falcaniformes) in southeastern Brazil

Although most raptor species are found mainly in the tropics, information on their home range and spatial requirements in the Neotropics is still scarce. In this study, we used radio telemetry to evaluate the home range and the habitat use and selection of five Roadside hawks, Rupornis magnirostris (Gmelin, 1788) in a heterogeneous landscape in southeastern Brazil. The average home range size calculated using the adaptive kernel method (95% isopleth) was 126.1ha (47.4-266.7ha), but using the minimum convex polygon method (95% isopleth) it was 143.54ha (32.6-382.3ha). The roadside hawk explored a wide variety of habitats, most of them opportunistically, as suggested in the literature. Despite this, habitat quality could influence home range size and promote habitat selection. The observation of habitat use as expected, as well as the relatively small home range size, could be related to the generalist/opportunistic behaviour of the roadside hawk.

The molecular systematics of Leiopotherapon unicolor (Günther, 1859): testing for cryptic speciation in Australia’s most widespread freshwater fish

Leiopotherapon unicolor is the most widespread freshwater fish species in Australia. A comprehensive allozyme and mitochondrial DNA 16S rRNA data set was assembled from 141 specimens of L. unicolor collected Australia-wide in order to test for cryptic speciation in this far-ranging species. Surprisingly, little genetic diversity was observed within L. unicolor and provided no evidence for the existence of cryptic species within this lineage. In contrast, a small sample set of L. aheneus used as the outgroup showed two highly divergent haplotypes strongly suggestive of cryptic speciation. L. unicolor has a number of ecological and life history attributes that may explain the lack of significant genetic divergence over substantial geographical distances. The occurrence of other widespread fish and crustacean species that also display only limited genetic diversity indicate that climate conditions more favourable to dispersal across central and northern Australia than is suggested by the extent of present-day aridity have occurred in the relatively recent geological past.

Feminine transports and transformations : textual performances of Australian women convicts and emigrants from 1788 to 1850

While scholars have critiqued early representations of the white colonial female in the form of the novel, short story, or historical narrative, analyses of poetry tend to be located only on that produced in Australia and often in light of a nascent national identity. This article examines how poetic renditions of the desolate woman might be viewed as part of imperialism's mythologising process, displacing more worrying versions of womanhood in relation to the new colonies. While social anxieties over the identity of the white colonial female would result in highly controlled productions of the female convict and female emigrant, this article demonstrates how they also prove unstable and point to a disruptive reality beyond language.

The 1859 election on the Ovens

The Victorian general election of 1859 occurred during a time of social transition and electoral reformation, which extended the vote to previously unrepresented adult males. Gold discoveries, including those on the Ovens, triggered the miners’ insistent demands for access to land and participation in the political process. The thesis identifies issues, which emerged during the election campaign on the Ovens goldfields, surrounding Beechworth. The struggle centred on the two Legislative Assembly seats for the Ovens and the one Legislative Council seat for the Murray District. Though the declared election issue was land reform, it concealed a range of underlying tensions, which divided the electorate along lines of nationality and religion. Complicating these tensions within the European community was the Chinese presence throughout the Ovens. The thesis suggests the historical memory of the French Revolution, the European Revolutions of 1848 and the Catholic versus Protestant revivals divided the Ovens goldfield community. The competing groups formed alliances; a Beechworth-centred grouping of traders, merchants and the Constitution’s editor, ensured the existing conservative agenda triumphed over those perceived radicals who sought reform. In the process the land hungry miners did not gain any political representation in the Legislative Assembly, while a prominent Catholic squatter who advocated limited land reform was defeated for the Legislative Council seat. Two daily Beechworth papers, Ovens and Murray Advertiser and its fierce competitor, the Constitution and Ovens Mining Intelligencer are the major primary sources for the thesis.

William Wardell's 1859 St John's College - a rare realisation of Pugin's ideal Catholic College?

William Wardell’s St John’s College, Sydney, considered the grandest and architecturally most distinguished university college in New South Wales, is an exceptional example of 19th century Gothic Revival architecture.  The information board outside the college states that St John’s is ‘a rare realisation of Pugin’s ideal Catholic College’ and further that ‘it demonstrates [Pugin]’s profound influence on the work of Wardell’. This is but a small part of the story. The commission for St John’s College was far more complex.  The correspondence between the architects, William Wardell, Edmund Blacket and others, and St John’s Council indicates that right from the beginning there was a general lack of understanding of Wardell’s original design concept for the building. This has continued to the present day, as evidenced by the information on the board outside St John’s College, in which it is incorrectly assumed that Wardell’s proposal included a quadrangle as featured in Pugin’s ‘ideal College’. This paper, based largely on primary sources, investigates such claims about St John’s, considers William Wardell and the Gothic Revival, examines St John’s College within the University of Sydney – its design and its translation and posits a few conclusions leading to new understandings.

Placas maxilo-dentárias em Rincossauros Hyperodapedon Huxley, 1859. Histologia e morfogênese maxilo-dental: nova abordagem.

O estudo das estruturas da placas maxilo-dentárias dos rincossauros Hyperodapedon Huxley, 1859, do Triássico da Formação Santa Maria, em nova abordagem histológica e ontogênica resultou na identificação da natureza do esmalte aprismático verdadeiro, de variados elementos histológicos dentinários e osteológicos, e de um centro de ossificação periosteal primário. Também foram encontradas evidências histológicas dos mecanismos de fusionamento maxilo-dentinário e amelo-maxilar. Com estes elementos, inferimos os modelos de organogênese dental, da ontogênese maxilar e dos mecanismos de fusionamento maxilodental. Encontrou-se uma singular e raríssima coroa dental, imatura e ainda não erupcionada, na região posterior da placa dental e assim evidenciou-se a correta posição da margem odontogenicamente ativa. Adicionalmente inferiu-se a localização da posição da lâmina dentária embrionária. Constatou-se a não formação de alvéolos dentários, de cemento radicular e do espaço necessário à formação do ligamento periodontal e, assim, se deduziu a não formação do folículo dental embriônico. As presenças de especiais elementos anatômicos e histológicos nos tecidos ósseos periapicais evidenciam o crescimento radicular contínuo, enquanto a forma e o fusionamento radicular imediato depõe a favor de uma função dentária fisiológica diferenciada para as baterias dentárias maxilares dos Rincossauros do gênero Hyperodapedon. Os mecanismos que possibilitaram o controle embriônico para a deposição das lamelas de tecido ósseo coronal e seu preciso fusionamento sobre o esmalte dentário, declinam por modificações nas funções tardias do órgão reduzido do esmalte e pela presença de uma membrana oral com funções osteogênicas e também protetivas, situada nas porções posteriores da placa maxilo-dentária em desenvolvimento. Mudanças heterocrônicas no tempo de diferenciação das células da crista neural embriônica e em seus derivados, como a lâmina dentária e órgãos dentários embrionários ou correlacionadas com a organogênese das placas maxilo-dentárias e seus anexos periodontais, todos como condições plesiomórficas para Diápsidas Triássicos, poderiam ser as causas responsáveis pela origem e evolução deste estranho aparelho estomatognático nos clados de Hyperodapedon sp..

Emprego de escama de sardinha (Sardinella brasiliensis - STEIDACHNER, 1859), conservada em glicerina, em ceratoplastias lamelares experimentais em cães

Estudou-se experimentalmente a escama de sardinha (Sardinella brasiliensis) como substituto de córneas no reparo de ceratectomias superficiais em cães. Utilizaram-se 14 animais, machos e fêmeas, sem raça definida, com peso médio de 10 kg, considerados sadios. Analisaram-se, macro e microscopicamente, as córneas receptoras bem como o material implantado aos 1, 3, 7, 14, 30 e 60 dias de pós-operatório. As evidências clínicas para a enxertia lamelar mostraram fotofobia e blefarospasmo mais incidentes nos períodos iniciais e intermediários, com tendência à regressão nos tardios. Revelaram edema discreto e igualmente regressivo; neoformação vascular mais incidente nas fases intermediárias e pouco nas tardias. O estudo microscópico evidenciou quadro reacional compatível com padrão benigno a exemplo do que fora visto macroscopicamente. Ambos retrataram boa adesividade da prótese, epitélio e estroma neoformados, sob e sobrepostos a ela. A transparência das córneas receptoras, junto às zonas de enxertia, manteve-se por 14 dias. Para a enxertia interlamelar, observou-se quadro reacional pouco significativo. Para ambas as enxertias, não foram observados sinais de extrusão do material implantado. A escama de sardinha pode ser empregada para fins tectônicos, com bons resultados em ceratoplastias lamelares em cães.

A educação destina a algumas crianças no Piauí (1730 1859)

L'histoire culturelle de l'éducation de l'enfant dans le Piauí, de l'année de 1730 à l'année de 1859, je mange écriture dans ce travail de thèse, est motivé dans l'analyse sócio-histórica de la forme scolaire à la lumière des théorisations des historiens Gui Vincent, Bernard Lahire et Daniel Thin, avec l'objectif de refléter concernant le passage d'instauration de la socialisation des enfants dans les écoles publiques, religieuses, particulières et domestiques. La recherche concernente à la thématique éducation de l'enfant dans leurs conceptions politiques et culturelles levou-em à définir, je mange objet d'étude, les manières d'instruire les enfants dans l'(s) école (s) et dans la (s) famille (s). La thèse du travail ici défendu est de que l'éducation destinée aux enfants dans le Piauí, dans la période de 1730 à 1859, était soumise aux acquisitions des habilités de lecture et d'écriture, principalement, analogue à leurs conceptions politiques et culturelles. La judicieuse recherche de corpus documentaire (licences, avertissements, troupeaux, lettres, correspondances, consultations, métiers, règlements, régiments, rapports, lois, dispositions, cartes scolaires, cartes d'inscriptions) pour l'écriture de la thèse il se procède nous quantités formulaires et digitales du Portugal, Brésil, Pará, Maranhão et Piauí. L'analyse de l'ensemble des sources nous a permis de comprendre que la socialisation scolaire de l'enfant dans le Piauí n'a pas maintenu le mêmes façons pendant cette longue période qui a été de 129 ans, malgré des récurrences, celui-là a acquis des formes et des sens divers qui variaient comme les circonstances politiques et culturelles, les exigences du commerce, les espaces et les sujets qui l'ont vécue intensément
