Patterns of morphological and genetic variation in the endemic Malagasy bat Miniopterus gleni (Chiroptera: Miniopteridae), with the description of a new species, M. griffithsi

Over the past decade, major advances have been made concerning the systematics and species diversity of Malagasy bats, largely based on specimens collected during inventories and associated morphological and molecular genetic studies. Herein we describe a new species of endemic bat from southern Madagascar, Miniopterus griffithsi sp. n., which is the sister taxa to Miniopterus gleni, a taxon described in 1995 (holotype from Sarodrano, just north of the Onilahy River in the southwest). Based on current information, M. griffithsi is found in the sub-arid bioclimatic zone, south of the Onilahy River, and M. gleni occurs in a variety of different bioclimatic zones, north of the Onilahy River to the northern portion of the island and on the near shore island of Ile Sainte Marie. The realization that M. griffithsi was a separate entity was first based on phylogeographic studies of the M. gleni complex. Comparisons using 397 bp of mitochondrial cytochrome b found a divergence of 1.2% within animals occurring across much of Madagascar north of the Onilahy River, 0.07% in those south of the Onilahy River, and 7.4% in populations separated by this river. Subsequently, morphological characters were identified that supported the specific separation of populations occurring south (M. griffithsi) and north of the Onilahy River (M. gleni), which include tragus shape, pelage coloration, and skull proportions.

Morphological, bioacoustical, and genetic variation in Miniopterus bats from eastern Madagascar, with the description of a new species

Recent molecular genetic work, combined with morphological comparisons, of Malagasy members of the bat genus Miniopterus (Family Miniopteridae), has revealed several cryptic species. Based on new specimens and associated tissues, we examine patterns of variation in the recently described species M. petersoni, the holotype of which comes from extreme southeastern Madagascar, and for which specimens from more northerly portions of eastern Madagascar were noted to show some morphological divergence from typical M. petersoni. On the basis of morphological and genetic (cytochrome b) characters we described a new species, M. egeri sp. nov. This taxon also shows bioacoustical differences from M. petersoni. Miniopterus egeri is widely distributed in the eastern portion of Madagascar across an elevational range from near sea level to 550 m. The specific status of moderately small Miniopterus from Montagne d'Ambre in the far north remains to be determined.

Description of systenobythere gen. nov. (Ostracoda, Crustacea) from the late miocene of southeastern Australia with comments on its problematical taxonomic and palaeoecological affinities

A new ostracod genus and species, Systenobythere archboldi, is described from late Miocene open neritic strata of southeastern Australia. Specimens occur in argillaceous glauconitic sands deposited in offshore continental shelf settings that were periodically influenced by coastal upwelling. Systenobythere archboldi possesses an adductor muscle scar pattern typical of the Bythocytheridae, but has a pentodont hinge and sieve-type normal pore canals atypical of this family.

The value of circles and the dangers of straight lines

This article focuses on how respectful learning relationships based on reciprocity between a Anglo-western raised educator and South Sudanese Australian students and graduates in social work and welfare courses in a regional location have (re)shaped the development of a research process. A reflective critique is intertwined with a description of my search (as an experienced practitioner but new researcher) for an appropriate ethical cross cultural framework for researching and advocating with a small ethnic population in a regional location. This includes a description of the process of exploring the need for, and positioning of, changing and re-creating relationships between the ‘researcher(s)’ and the ‘researched’ as co-authors; co-researchers; collaborators and participants to address issues of selfdetermination and power in the context of cross cultural research, education and human rights. The motivation to research seems a pivotal part of ethics in cross cultural research. As an educator I became concerned that the courses I taught in, and my own teaching practices, were (unintentionally) discriminatory. There appeared to be a lack of acknowledgement and/or action regarding the ingrained Western whiteness permeated and privileged knowledge and approaches in the construction and delivery of courses. I did not think I was adequately responding to, recognising or incorporating the different knowledge’s, strengths and needs of South Sudanese Australian students and graduates. There was a lack of fit between the academic rhetoric of human rights and diversity and my/our educator practice. This article explores the ‘corralling’ effect of mainstream research culture with attention to its potential for seduction and corruption that tends to separate the passion from the researcher, the researcher from the researched, and the actual issue(s) of concern ….from everyone.

Metaphoric re-description of organisational culture for mid-career female academics: monkeys, raccoon, bees and horses

The paper explores how metaphors can be used to analyse the experiences of women working in higher education. The paper discusses research on women working in higher education across three Australian Universities and the implications of their metaphorical uses to theorize about women in higher education. 

We ‘are’ rhetoric. Get over it!

This paper argues that a better understanding of public relations would help us to get an urgently needed better understanding of people. It explains why public relations should be considered the contemporary manifestation of the millennia-old art of rhetoric which in turn should be considered the basis of, at least western culture. This article introduces a thesis that understanding rhetoric properly will lead to the best way of understanding public relations properly. It will critique existing writers about the rhetoric to public relations nexus to suggest that there is a crucial need to more carefully consider the true relevance
of massively organised deliberate persuasive discourse. The urgency is because few of these commentators quite capture the extent to which public relations and related  activities are creating us. It will explain why we are almost unconscious of this process and it will point out that by contrast ancient sophists and the more accomplished pre-modern rhetoricians have always been aware of this ‘construction of people process’. The approach of this paper is premised on the observation of classicist Werner Jaeger who explains that rhetoric is at the centre of being human. When explaining the use of  grammar, rhetoric and dialectic by Greek Enlightenment sophists he writes that: “This educational technique is one of the greatest discoveries which the mind of man has ever made: it was not until it explored these three of its activities that the mind apprehended the hidden law of its own structure.” (Jaeger, 1947:314)

The rhetoric of ‘community’ : ABC local radio's coverage of the 2009 Victorian bushfires

This article joins recent debates in media and communication studies concerning audience participation in news journalism. Specifically, we investigate the impact of an increasing reliance on audience-generated content on newsroom practice in traditional media organisations. We do this by recounting and analysing the experiences of journalists involved in ABC Radio's coverage of the dramatic Victorian bushfires of early 2009, which relied heavily in listener contributions and was closely integrated with the ABC's online coverage. Interviews with two staff at ABC Gippsland, and the ABC's Manager of Emergency Broadcasting provide the basis for a case study of the kinds of tensions that media workers routinely confront within an organisation like the ABC. The interviews suggest that in negotiating the possibility of increased audience participation, journalists and their managers are thinking about much more that the rhetorics of democracy and the validity of news values: their focus is also on a complex structure, the need for skill (re)development and the precise mechanics of creating and maintaining productive relationships with local communities. The significance of the research lies in its attempt to bring together a number of related factors: the increasingly active role of audiences in generating and supplying news content; the impact of digital communications technologies on news production practices; and the ABC's ongoing development of its now contested role as an 'emergency broadcaster'.
