Observations of loxocythere (loxocythere) ouyenensis (chapman, 1914) (ostracoda) from the cenozoic of S.E. Australia with comments on species attributed to microcytherura müller, 1894 and hemiparvocythere hartmann, 1982 from Australian and New Zealand ma

The type material of Loxocythere (Loxocythere) ouyenensis (Chapman, 1914) from mid Cenozoic strata of the Mallee Bore No. 11 in the Murray Basin, S.E. Australia is partially redescribed and refigured. This species belongs to a discrete group of large elongate Cenozoic fossil and living Loxocythere species, the carapaces of which possess sub-rectangular inner margin outlines, and broadly rounded posterior extremities. Some much smaller but otherwise very similarly shaped species, that have previously been placed under the genus Microcytherura (i.e. Microcytherura? peterroyi Yassini and Jones, 1995) or the genus Hemiparvocythere Hartmann, 1982 (i.e. Hemiparvocythere Iagunicola Hartmann, 1982), are also known from marine Cenozoic strata and modern seas of the Australasian region. There is a marked difference in the shape of the inner margin between this group of small Australasian forms and European species of Microcytherura s.s .. The former have broadly rounded posterior inner margins, whilst the latter have acutely rounded posterior inner margins. The latter also usually present posterior extremities located well below mid carapace height. It is here argued that this difference in inner margin shape between smaller Australasian species such as Microcytherura? peterroyi, and European species of Microcytherura s.s ., suggests that there is not a direct phylogenetic relationship between these two species groups.

The modern Medea : Euripides, anti-imperialism and infanticide

Euripides' Medea has been reinvented several times in the twentieth century. This paper uncovers the impetus that informs the lineage of Medeas that are overt in their politicisation of the problems of colonialism and/or institutionalised gender dissymmetry: the Medeas of Pier Paolo Pasolini, Heiner Mller, Brendan Kennelly, Liz Lochhead, Christa Wolf, Diana Wakoski, Tony Harrison - and more recently Wesley Enoch. What, however, lends the Euripidean narrative to such politicisations? To answer this question, the paper looks back to Euripides' play, offering a reappraisal of its representation of infanticide. The paper argues that while this motif is routinely dismissed in the scholarship as a demonising representation of the cultural and sexual Other, the infanticide motif is also the key to understanding Medea's radicality and politicisation of rights-bearing subjectivity in its ancient and modern incarnations.

Detection of endocrine disrupting chemicals in aerial invertebrates at sewage treatment works

Endocrine disrupting chemicals (EDCs) constitute a diverse group of chemical compounds which can alter endocrine function in exposed animals. Whilst most studies have focussed on exposure of wildlife to EDCs via aquatic routes, there is the potential for transfer into the terrestrial food chain through consumption of contaminated prey items developing in sewage sludge and waste water at sewage treatment works. In this study, we determine levels of EDCs in aerial insects whose larval stages develop on percolating filter beds at sewage treatment works. We compare absolute concentrations of known EDCs with those collected from aquatic environments not exposed to sewage effluent outflow. Our findings document for the first time that aerial invertebrates developing on sewage filter beds take up a range of chemicals thought to be incorporated from the sewage effluent, which act as endocrine disruptors. For two synthetic chemicals (17α-ethinylestradiol and butylated hydroxy aniline), concentrations were significantly higher in insects captured around percolating filter beds than sites over 2 km from the nearest sewage works. A number of species of insectivorous bats and birds, some of which are declining or threatened, use sewage works as principle foraging sites. We calculate approximate exposure levels for a species of bat known to forage within sewage works and suggest that further research is warranted to assess the ecological implications of consuming contaminated invertebrate prey

Photochromic wool fabric by sol-gel coating and photochromism

The application of photochromism in textiles has potential to create new opportunities to develop fancy colour-changing effects in fashionable textiles, as well as smart garments capable of protecting wearers from the effects of UV irradiation and responding to environmental changes. This book presents a coating method for achieving quick and obvious photochromic effects on wool fabrics using conventional photochromic dyes and hybrid silicas. It covers details about fabricating different types of photochromic dye-silica coatings, measuring their optical performance, assessing some physical characterisations of the coatings, and measuring the effects of the coatings on fabric performance.

Motion Bank : Phase One

 Motion Bank Phase One (2010-2013) was a four-year international and interdisciplinary research project of The Forsythe Company providing a broad context for research into choreographic practice. The main focus was on the creation of on-line digital scores in collaboration with guest choreographers, to be made publicly available via this website. For Phase One, the guest choreographers were Deborah Hay, Jonathan Burrows & Matteo Fargion, Bebe Miller and Thomas Hauert. Teams from the Motion Bank Score Partners worked with these artists to make their diverse choreographic approaches accessible in new ways through the digital medium with the results published here: http://scores.motionbank.org/. Alongside this core research, Motion Bank Education Partners and an International Education Workgroup researched ways to integrate the new on-line digital scores and related choreographic resources produced by other artists into their academic programs. Accompanying the Motion Bank education research was an interdisciplinary initiative titled Dance Engaging Science aiming to stimulate new forms of collaborative research involving dance practice. Motion Bank public events offered at The Frankfurt Lab included performances and talks with the guest choreographers as well as a series of Motion Bank Workshops with internationally recognized practitioners from different fields. An extensive series of reports and documentation on all Motion Bank activities and results are available on-line at http://motionbank.org.

American exceptionalism: population trends and flight initiation distances in birds from three continents.

All organisms may be affected by humans' increasing impact on Earth, but there are many potential drivers of population trends and the relative importance of each remains largely unknown. The causes of spatial patterns in population trends and their relationship with animal responses to human proximity are even less known.

Animal behaviour and cancer

Scientists are increasingly coming to realize that oncogenic phenomena are both frequent and detrimental for animals, and must therefore be taken into account when studying the biology of wildlife species and ecosystem functioning. Here, we argue that several behaviours that are routine in an individual's life can be associated with cancer risks, or conversely prevent/cure malignancies and/or alleviate their detrimental consequences for fitness. Although such behaviours are theoretically expected to be targets for natural selection, little attention has been devoted to explore how they influence animal behaviour. This essay provides a summary of these issues as well as an overview of the possibilities offered by this research topic, including possible applications for cancer prevention and treatments in humans.

Flight initiation distances in relation to sexual dichromatism and body size in birds from three continents

Predators exert strong selection pressures on their prey. Prey would therefore benefit by adjusting their behaviour to the risk of predation, while predators conversely would benefit from adjusting their behaviour to that of their prey. Extravagant ornamentation has evolved to attract mates and/or successfully compete with conspecifics of the same sex to secure high mating success, even if that occurs at a cost of increased risk of predation. Thus, sexually dichromatic species may be more susceptible to predation than sexually monochromatic species, and the presence of compensation is indicative of such species being more vulnerable. If extravagant ornamentation is costly in terms of predation risk, then we should expect sexually dichromatic species to have longer flight initiation distances (FID) than sexually monochromatic species. If ornamentation is acquired as a handicap with only individuals in prime condition being able to display with the smallest viability cost, we should expect sexually dichromatic individuals to have shorter FID than sexually monochromatic individuals. Such differences among individuals should, on an evolutionary time scale, translate into differences in FID being related to differences in sexual dichromatism among species. We investigated the relationship between FID and sexual dichromatism in phylogenetic analyses, while accounting for effects of continent (Australia, North America, and Europe), body mass, the interaction between sexual dichromatism and body mass and the interaction between sexual dichromatism and continent. In an analysis of 447 species we found shorter FID in sexually dichromatic than in sexually monochromatic species (consistent with the handicap hypothesis because sexually dichromatic species took greater risks), especially so at large body size. FID differed among continents and the relative difference in FID between sexually monochromatic and sexually dichromatic species was larger in Europe than in Australia and North America. These differences among continents may be attributed to latitudinal effects of predation. These findings are important for current ideas about the evolution of secondary sexual characters because they imply covarying continental differences in predation, especially for large bodied sexually dichromatic species.
