Full Consideration

Evolutionary ecology is at the precipice of a paradigm shift. For many years and through the early years of the 21st century, mitochondrial genomes were dismissed as unimportant to the evolution of complex life. Variation within mitochondrial genomes was proposed to be functionally neutral. These conceptions about mitochondrial genomes and mitonuclear genomic interactions have begun to change within the past decade, but currently accepted theories of sexual selection and speciation were proposed before the discovery of the mitochondrial genome. Evolutionary ecology has yet to fully appreciate the fundamental implications of two genomes coding for the core respiratory enzymes of eukaryotes. This chapter promotes a fundamental rethinking of key theories in evolutionary ecology with full consideration of the necessity of coadaptation of mitochondrial and nuclear genes.

Austropuccinia Psidii

Mitochondrial genomes are highly conserved in many fungal groups, and they can help characterize the phylogenetic relationships and evolutionary biology of plant pathogenic fungi. Rust fungi are among the most devastating diseases for economically important crops around the world. Here, we report the complete sequence and annotation of the mitochondrial genome of Austropuccinia psidii (syn. Puccinia psidii), the causal agent of myrtle rust. We performed a phylogenomic analysis including the complete mitochondrial sequences from other rust fungi. The genome composed of 93.299 bp has 73 predicted genes, 33 of which encoded nonconserved proteins (ncORFs), representing almost 45% of all predicted genes. A. psidii mtDNA is one of the largest rust mtDNA sequenced to date, most likely due to the abundance of ncORFs. Among them, 33% were within intronic regions of diverse intron groups. Mobile genetic elements invading intron sequences may have played significant roles in size but not shaping of the rust mitochondrial genome structure. The mtDNAs from rust fungi are highly syntenic. Phylogenetic inferences with 14 concatenated mitochondrial proteins encoded by the core genes placed A. psidii according to phylogenetic analysis based on 18S rDNA. Interestingly, cox1, the gene with the greatest number of introns, provided phylogenies not congruent with the core set. For the first time, we identified the proteins encoded by three A. psidii ncORFs using proteomics analyses. Also, the orf208 encoded a transmembrane protein repressed during in vitro morphogenesis. To the best of our knowledge, we presented the first report of a complete mtDNA sequence of a member of the family Sphaerophragmiacea.

The nature of diaspora is changing in the 21st century. Yet many of the communication issues remain the same. At the heart of it is multilingual and intercultural communication across time and space. There is much that applied linguists can contribute to the understanding of diaspora in the era of globalization. This article discusses some of the core issues of communication between the diaspora and the homeland, the past and the present, the individual and the community, and the sense of belonging and the ascribed category with a detailed analysis of empirical data collected through linguistic ethnography in the Chinese diaspora in Britain and elsewhere. It also highlights the significance of dynamic multilingualism in everyday communication.

AbstractLiligo glacier, in the central eastern Karakoram, Pakistan, is a small, south-to-north-flowing glacier situated in a transverse valley on the left (south) side of Baltoro glacier. New processing of satellite imagery enables a better quantification of terminus oscillations over the past 30 years. From the beginning of the 1970s to the beginning of the 21st century, Liligo glacier advanced about 2 km (60ma–1). The progress was characterized by a significant evolution of terminus morphology, similar to that observed on the same glacier during the advance event near the beginning of the 20th century, and to those of many other Karakoram glaciers. This suggests indications of a surge-type mechanism. Field observations performed in 2004 indicated there was probably no confluence at that time between Liligo and Baltoro glaciers and that a quiescent phase had started in the early years of the 21st century.

Abstract Background Ixodes barkeri, a tick with a distinctive ventrolateral horn-like projection on palpal segment 1, was described in 2019 from two male ticks from the Wet Tropics of Far North Queensland, Australia. However, females lie at the core of the taxonomy and subgenus classification of Ixodes, hence we sought specimens of female ticks, successfully recovering females, plus nymphs and larvae. Mitochondrial genomes are also desirable additions to the descriptions of species of ticks particularly with regard to subgenus systematics. So, we sequenced the mt genomes of I. barkeri Barker, 2019 and the possible relatives of I. barkeri that were available to us (I. australiensis Neumann, 1904, I. fecialis Warburton & Nuttall, 1909, and I. woyliei Ash et al. 2017) with a view to discovering which if any of the subgenera of Ixodes would be most suitable for I. barkeri Barker, 2019. Results The female, nymph, larva, and mitochondrial genome of Ixodes barkeri Barker, 2019 are described for the first time and the male of I. barkeri is redescribed in greater detail than previously. So far, I. barkeri is known only from a monotreme, the short-beaked echidna, Tachyglossus aculeatus (Shaw, 1792), from the highland-rainforests of Far North Queensland, Australia. Conclusions Our phylogeny from entire mitochondrial genomes indicated that I. barkeri, and indeed I. woyliei Ash et al. 2017, another tick that was described recently, are best placed in the subgenus Endopalpiger Schulze, 1935.

Core Concepts

Eukaryotes were born of a chimeric union of two prokaryotes. The legacy of this fusion is organisms with both a nuclear and mitochondrial genome that must work in a coordinated fashion to enable cellular respiration. The coexistence of two genomes in a single organism requires tight coadaptation to enable function. The need for coadaptation, the challenge of co-transmission, and the possibility of genomic conflict between mitochondrial and nuclear genes have profound consequences for the ecology and evolution of eukaryotic life. This book defines mitonuclear ecology as an emerging field that reassesses core concepts in evolutionary ecology in light of the necessity of mitonuclear coadaptation. I discuss and summarize research that tests new mitonuclear-based theories for the evolution of sex, two sexes, senescence, a sequestered germ line, speciation, sexual selection, and adaptation. The ideas presented in this book represent a paradigm shift for evolutionary ecology. Through the twentieth century, mitochondrial genomes were dismissed as unimportant to the evolution of complex life because variation within mitochondrial genomes was proposed to be functionally neutral. These conceptions about mitochondrial genomes and mitonuclear genomic interactions have been changing rapidly, and a growing literature in top journals is making it increasingly clear that the interactions of the mitochondrial and nuclear genomes over the past 2 billion years have played a major role in shaping the evolution of eukaryotes. These new hypotheses for the evolution of quintessential characteristics of complex life hold the potential to fundamentally reshape the field of evolutionary ecology and to inform the emerging fields of mitochondrial medicine and mitochondrial-based reproductive therapies.

Municipal Level

Under the term “Hilfe zur Arbeit” (aid for work) the federal law of social welfare subsumes all kinds of labour disciplining instruments. First, the paper shows the historical connection of welfare and labour disciplining mechanisms in the context of different periods within capitalist development. In a second step, against the background of historical experiences, we will analyse the trends of “Hilfe zur Arbeit” during the past two decades. It will be shown that by the rise of unemployment, the impact of labour disciplining aspects of “Hilfe zur Arbeit” has increased both on the federal and on the municipal level. For this reason the leverage of the liberal paradigm would take place even in the core of social rights.

At a time when the Union between Scotland and England is once again under the spotlight, Remembering the Past in Nineteenth-Century Scotland examines the way in which Scotland’s national heroes were once remembered as champions of both Scottish and British patriotism. Whereas 19th-century Scotland is popularly depicted as a mire of sentimental Jacobitism and kow-towing unionism, this book shows how Scotland’s national heroes were once the embodiment of a consistent, expressive and robust view of Scottish nationality. Whether celebrating the legacy of William Wallace and Robert Bruce, the reformer John Knox, the Covenanters, 19th-century Scots rooted their national heroes in a Presbyterian and unionist view of Scotland’s past. Examined through the prism of commemoration, this book uncovers collective memories of Scotland’s past entirely opposed to 21st-century assumptions of medieval proto-nationalism and Calvinist misery. Detailed studies of 19th-century commemoration of Scotland’s national heroes Uncovers an all but forgotten interpretation of these ‘great Scots’ Shines a new light on the mindset of nineteenth-century Scottish national identity as being comfortably Scottish and British Overturns the prevailing view of Victorian Scottishness as parochial, sentimental tartanry

To displace a character in time is to depict a character who becomes acutely conscious of his or her status as other, as she or he strives to comprehend and interact with a culture whose mentality is both familiar and different in obvious and subtle ways. Two main types of time travel pose a philosophical distinction between visiting the past with knowledge of the future and trying to inhabit the future with past cultural knowledge, but in either case the unpredictable impact a time traveller may have on another society is always a prominent theme. At the core of Japanese time travel narratives is a contrast between self-interested and eudaimonic life styles as these are reflected by the time traveller's activities. Eudaimonia is a ‘flourishing life’, a life focused on what is valuable for human beings and the grounding of that value in altruistic concern for others. In a study of multimodal narratives belonging to two sets – adaptations of Tsutsui Yasutaka's young adult novella The Girl Who Leapt Through Time and Yamazaki Mari's manga series Thermae Romae – this article examines how time travel narratives in anime and live action film affirm that eudaimonic living is always a core value to be nurtured.

This article investigates human–nature relations in the light of the recent call for degrowth, a radical reduction of matter–energy throughput in over-producing and over-consuming cultures. It outlines a culturally sensitive response to a (conceived) paradox where humans embedded in nature experience alienation and estrangement from it. The article finds that if nature has a core, then the experienced distance makes sense. To describe the core of nature, three temporal lenses are employed: the core of nature as ‘the past’, ‘the future’, and ‘the present’. It is proposed that while the degrowth movement should be inclusive of temporal perspectives, the lens of the present should be emphasised to balance out the prevailing romanticism and futurism in the theory and practice of degrowth.
