Thomas Mitchell and the Wellington caves: The relationship among science, religion, and aesthetics in early-nineteenth-century Australia

THOMAS MITCHELL (1792–1855), explorer and Surveyor-General in New South Wales between 1828 and 1855, was a talented and competent draughtsman who was responsible for the original sketches and even some of the lithographs he used to illustrate his two journals of exploration, published in 1838 and 1848. In this paper, I will be concerned with the 1838 journal, entitled Three Expeditions into the Interior of Eastern Australia; with descriptions of the recently explored region of Australia Felix, and of the Present Colony of New South Wales. On the whole, it is a detailed and lavishly illustrated account of the land Mitchell encountered, along with its inhabitants and natural history. My particular interest is in offering an explanation for differences between a sepia sketch depicting a cave at Wellington, NSW, that Mitchell prepared as one of the illustrations for geological material included in this journal, and the final lithograph.

Data compilation on the biological response to ocean acidification: environmental and experimental context of data sets and related literature

The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.

On the microstructure, growth pattern and original porosity of belemnite rostra: insights from calcitic Jurassic belemnites

Calcitic belemnite rostra are usually employed to perform paleoenvironmental studies based on geochemical data. However, several questions, such as their original porosity and microstructure, remain open, despite they are essential to make accurate interpretations based on geochemical analyses.This paper revisits and enlightens some of these questions. Petrographic data demonstrate that calcite crystals of the rostrum solidum of belemnites grow from spherulites that successively develop along the apical line, resulting in a “regular spherulithic prismatic” microstructure. Radially arranged calcite crystals emerge and diverge from the spherulites: towards the apex, crystals grow until a new spherulite is formed; towards the external walls of the rostrum, the crystals become progressively bigger and prismatic. Adjacent crystals slightly vary in their c-axis orientation, resulting in undulose extinction. Concentric growth layering develops at different scales and is superimposed and traversed by a radial pattern, which results in the micro-fibrous texture that is observed in the calcite crystals in the rostra.Petrographic data demonstrate that single calcite crystals in the rostra have a composite nature, which strongly suggests that the belemnite rostra were originally porous. Single crystals consistently comprise two distinct zones or sectors in optical continuity: 1) the inner zone is fluorescent, has relatively low optical relief under transmitted light (TL) microscopy, a dark-grey color under backscatter electron microscopy (BSEM), a commonly triangular shape, a “patchy” appearance and relatively high Mg and Na contents; 2) the outer sector is non-fluorescent, has relatively high optical relief under TL, a light-grey color under BSEM and low Mg and Na contents. The inner and fluorescent sectors are interpreted to have formed first as a product of biologically controlled mineralization during belemnite skeletal growth and the non-fluorescent outer sectors as overgrowths of the former, filling the intra- and inter-crystalline porosity. This question has important implications for making paleoenvironmental and/or paleoclimatic interpretations based on geochemical analyses of belemnite rostra.Finally, the petrographic features of composite calcite crystals in the rostra also suggest the non-classical crystallization of belemnite rostra, as previously suggested by other authors.

Céphalopodes des mers d'Indochine

During 1920-1921, Mr. Krempf, Director of the Fisheries and Oceanographic Service of Indochina, collected samples of cephalopods in different places along the coast of Indochina, especially on the island of Poulo-Condor, located about 100 miles east from Camau. The present paper deals with the description of Sepia harmeri, Loligo singhalensis, Sepioleuthis lessoniana, Sepioleuthis krempfi, Octopus fantonianus, Octopus dollfusi, Octopus tuberculatus.

Brote de toxiinfección alimentaria por Norovirus: estudio epidemiológico y medidas sanitarias aplicadas para evitar su recurrencia

Objetivo: Debido a que las Toxiinfecciones alimentarias (TIA) originan daños para la salud, pérdidas económicas y requieren la intervención directa sobre la fuente de contaminación, el objetivo fue realizar un estudio clínico, epidemiológico e higiénico sanitario de un brote de TIA, sin posibilidad de análisis microbiológico. Diseño: Estudio descriptivo y de casos-controles. Emplazamiento: Comunidad de Munera. Albacete (España). Participantes: Población compuesta por las personas asistentes a tres comidas de celebración de comunión. Mediciones Principales: Se realizó una encuesta telefónica epidemiológica y se calcularon odds ratio (OR) crudas y ajustadas con intervalos de confianza al 95 %. Se realizó un modelo de regresión logística multivariante e inspección sanitaria del restaurante. Resultados: Se expusieron 204 personas y fueron encuestadas 62 (32 afectados y 30 sanos). La tasa global de ataque fue de 51,6 % y el periodo de incubación de 33 horas. Los síntomas principales: dolor abdominal, vómitos y diarreas. El tiempo de duración de la enfermedad fue 38 horas. Se observó asociación con la "Ensalada" (OR-cruda: 7,5; IC95: 1,48-37,91), resultando al borde de la significación estadística la relación con "Sepia" (ORc: 4,15; IC95: 1,00-17,18) y "Marisco" (ORc: 4,57; IC95: 0,87-24,08). La OR-ajustada para la "Ensalada" fue 5,41 (IC95: 1,00-29,23). La inspección sanitaria comprobó la existencia de deficiencias de estructura, limpieza, desinfección y formación de manipuladores. Conclusiones: La Ensalada fue el único alimento asociado estadísticamente, pero no podemos descartar la Sepia y Mariscos; mediante la inspección sanitaria y los criterios de Kaplan, es posible clasificarla como una infección por Norovirus. Se aplicaron medidas especiales de funcionamiento en el restaurante para evitar reincidencia del brote.

Trammel net selectivity studies in the Algarve (southern Portugal), gulf of cadiz (Spain), Basque coutry (Spain) and cyclades islands (Greece)

Trammel net fisheries were studied in four areas: the Cantabrian Sea (Basque Country, Spain), the Algarve (Southern Portugal), the Gulf of Cádiz (Spain) and the Cyclades Islands (Greece). Surveys were carried out in order to identify trammel net métiers and to characterise the gear used. Trammel nets were among the most important gears used in the small-scale fisheries, with up to 9 different métiers identified in each area. The most important métiers in the Algarve and the Gulf of Cádiz were those for cuttlefish (Sepia officinalis) and soles (Solea senegalensis, Microchirus azevia, Synaptura lusitanica). In the Cantabrian Sea, sole (Solea vulgaris), shellfish (several species) and scorpion fish (Scorpaena spp.) métiers dominated while a variety of species where targeted in the multi-species trammel net fishery in the Cyclades. In each area, experimental trammel nets of six different types (combinations of 2 large mesh outer panel sizes and 3 small mesh outer panels) corresponding to the most common métier, were constructed and fishing trials carried out on a seasonal basis (4 seasons in the Cantabrian Sea, Algarve and Cyclades and 2 in the Gulf of Cádiz) using chartered commercial fishing vessels. Overall, 271, 360, 185 and 185 km of trammel nets were fished in the experimental fishing trials in the Cantabrian Sea, Algarve, Gulf of Cádiz and Cyclades Islands respectively.

In praise of the everyday

The following forgotten text is flawed. It is a failure. It has many mistakes but few regrets. It was written 20 years ago and first appeared in the Melbourne Super 8 Group Newsletter Issue 135 in May 1998, 25 years after I solarized my first 25 feet of 16mm film of the Carlton Cemetery fence, just down the road from Goodtime Studios and did my first bit of sepia toning in a Russian processing tank that still lies with its warped plastic spiral in my garage in suburban Melbourne. As Pearls Before Swine sang in one of their songs, a faint memory now; 'The More things change, the more they stay the same'. They were not the first to say this. Technology continues to develop massively and the rubble of its passing slowly recedes to invisibility. I continue to live through this conundrum every day. It sings me to sleep. It wakes me up.

Size selectivity of trammel nets in southern European small-scale fisheries

Trammel net size selectivity was studied for the most important metiers in four southern European areas: the Cantabrian Sea (Atlantic, Basque Country, Spain), the Algarve (Atlantic, southern Portugal), the Gulf of Cadiz (Atlantic, Spain) and the Cyclades Islands (Mediterranean, Aegean Sea, Greece). These metiers were: cuttlefish (Sepia officinalis) and soles (Solea senegalensis, Microchirus azevia, Synaptura lusitanica) in the Algarve and the Gulf of Cadiz, sole (Solea solea) in the Cantabrian Sea and mixed fin-fish in the Cyclades. In each area, experimental trammel nets of six different types (combinations of two large outer panel mesh sizes and three small inner panel meshes) were constructed. Fishing trials were carried out on a seasonal basis (four seasons in the Cantabrian Sea, Algarve and Cyclades and two seasons in the Gulf of Cadiz) with chartered commercial fishing vessels. Overall, size selectivity was estimated for 17 out of 28 species for which sufficient data were available. Trammel nets generally caught a wide size range of the most important species, with length frequency distributions that were skewed to the right and/or bi-modal. In many cases the length frequency distributions of the different nets were highly overlapped. The Kolmogorov-Smirnov test also showed that the large outer panel meshes generally had no effect in terms of size selectivity, while the opposite was true for the small inner panel ones. Six different selectivity models (normal scale, normal location, gamma, log-normal, bi-modal and gamma semi-Wileman) were fitted to data for the most abundant species in the four areas. For fish, the bi-modal model provided the best fits for the majority of the data sets, with the uni-modal models giving poor fits in most cases. For Sepia officinalis, where trammelling or pocketing was the method of capture in 100% of the cases, the logistic model fitted by maximum likelihood was judged to be more appropriate for describing the size selective properties of the trammel nets. Our results, which are among the first ones on trammel net selectivity in European waters, will be useful for evaluating the impacts of competing gear for the socio-economically important small-scale static gear fisheries.
