Dragonfly Species

Here, we investigate the evolutionary history of five northern dragonfly species to evaluate what role the last glaciation period may have played in their current distributions. We look at the population structure and estimate divergence times for populations of the following species: Aeshna juncea (Linnaeus), Aeshna subarctica Walker, Sympetrum danae (Sulzer), Libellula quadrimaculata Linnaeus and Somatochlora sahlbergi Trybom across their Holarctic range. Our results suggest a common phylogeographic pattern across all species except for S. sahlbergi. First, we find that North American and European populations are genetically distinct and have perhaps been separated for more than 400,000 years. Second, our data suggests that, based on genetics, populations from the Greater Beringian region (Beringia, Japan and China) have haplotypes that cluster with North America or Europe depending on the species rather than having a shared geographic affinity. This is perhaps a result of fluctuating sea levels and ice sheet coverage during the Quaternary period that influenced dispersal routes and refugia. Indeed, glacial Beringia may have been as much a transit zone as a refugia for dragonflies. Somatochlora sahlbergi shows no genetic variation across its range and therefore does not share the geographic patterns found in the other circumboreal dragonflies studied here. Lastly, we discuss the taxonomic status of Sympetrum danae, which our results indicate is a species complex comprising two species, one found in Eurasia through Beringia, and the other in North America east and south of Beringia. Through this study we present a shared history among different species from different families of dragonflies, which are influenced by the climatic fluctuations of the past.

The Fourth Memoir, published in my Zoological Researches and Illustrations, No. III. page 69, &c., having first made known the real nature of the Cirripedes , the key of which remained concealed in their metamorphosis, it might have been expected that some naturalist favourably situated to investigate the oceanic tribe of these animals, would have been the first to make the same discovery in regard to these, and thereby complete their natural history. It was scarcely to be expected that the honour of this discovery also should be reserved for the author, fixed to one spot, where none of them naturally exist, and are but casually thrown upon our shores by the waves of the Atlantic, attached to pieces of wreck, or brought into port fixed to the bottoms of ships returning from distant voyages. Fortunately, however, two ships of this description came into this harbour (Cork), one from the Mediterranean, the other from North America, which, not being sheathed with copper, had their bot­toms literally covered with Barnacles of the three genera of Lepas , Cineras , and Otion ; and having persons employed expressly for the purpose, numbers of these were brought alive in sea water, amongst which were many with the ova in various stages of their progress, and some ready to hatch, which they eventually did in prodigious numbers, so as to enable him to add the proof of their being, like the Balani, natatory Crusta­cea in their first stage , but of a totally different facies and structure; a circumstance which determines the propriety of the separation of the Cirripedes into two tribes, and evinces the sagacity of Mr. MacLeay in being the first to indicate that these two tribes, the Balani and Lepades , were not so closely related as generally supposed. The larvæ of the Balani , described in Memoir IV. under the external appearance of the bivalve Monoculi ( Astracoda ), have a pair of pedunculated eyes, more numerous and more completely developed members, approximating to those of Cyclops , and of the perfect Triton ; while, in the present type, or Lepades , the larva resembles some­what that of the Cyclops , which Müller, mistaking for a perfect animal, named Amymone , and which can be shown to he common to a great many of the Entomostraca ; or the resemblance is still more striking to that of the Argulus Armiger of Latreille, which, in fact, is but an Amymone furnished with a tricuspidate shield at the back.

Strategic Policies

Michel de Certeau, a French philosopher trained in history and ethnography, was a peripatetic teacher in Europe, South America and North America. His thought has inflected four areas of philosophy. He studied how mysticism informs late-medieval epistemology and social practice. With the advent of the Scientific Revolution, the affinities the mystic shares with nature and the cosmos become, like religion itself, repressed or concealed. An adjunct discipline, heterology, thus constitutes an anthropology of alterity, studying the ‘other’ and the destiny of religion since the sixteenth century. De Certeau opens the hidden agendas that make representations of the past a function of social pressures, so that sometime histories are rearticulated in mirrored or subversive forms. This subversion makes accessible a general philosophy of invention that works within and against the strategic policies of official institutions. De Certeau’s writings also belong to activism, the history of ideological structures, psychoanalysis, and post-1968 theories of writing (écriture) as defined by Deleuze, Derrida, Foucault and Lyotard.

Abstract The book under review serves as a significant contribution to the field of Trans-Himalayan linguistics. Designed as a vade mecum for readers with little linguistic background in these three languages, Nathan W. Hill’s work attempts, on the one hand, a systematic exploration of the shared history of Burmese, Tibetan and Chinese, and, on the other, a general introduction to the reader interested in obtaining an overall understanding of the state of the art of the historical phonology of these three languages. Whilst it is acknowledged that the book in question has the potential to be a solid contribution to the field, it is also felt that few minor issues can be also addressed.

The emergence of the trade paperback in the 1980s crucially transformed the way in which Australian literature was received in North America. The publication history of Patrick White on the one hand and Glenda Adams and Peter Carey on the other shows how younger writers actually made more of a cultural impact, despite White’s Nobel Prize, because the form in which they met the reading public was one freed from the modernist binary between high and low culture. The 1980s saw the emergence of a more globalized and more culturally pluralistic world—though also one much more pervaded by multinational capital—in which Australian writers flourished.

Research on this topic in Europe and North America has reached a new stage. Prior to 1970, historians told a story of progress in which modern individuals gradually gained mastery of emotions. After 1970 this older approach was put into doubt. Since 1990 research into the history of emotions has increasingly relied on a new methodology, based on the assumption that emotion is a domain of effort, and that it is possible to document variance between emotional standards, on the one hand, and the greater or lesser success of individuals in conforming to them, on the other. Emotional standards are now assumed to display a history that is not progressive, but reflects distinctive features of each period.

This nomenclatural note addresses the problem regarding the taxonomic status of the extinct large nimravid Pogonodon Cope, 1880 (Chordata. Mammalia, Nimravidae), from the Oligocene of North America and its junior homonym, the recent triphorid marine snail Pogonodon Bouchet, 1997 (Mollusca, ) from the Mediterranean. Here we propose Ionthoglossa nov. gen. as a substitute name for the latter and provide a brief history of the two taxa from the literature available.

We review the status of an Iranian gecko population previously referred to Tropiocolotes cf. steudneri and describe it as a new species, Tropiocolotes hormozganensis sp. nov. We discuss the taxonomic history of this population and compare its characters with those of the other species in the genus. The new species is distinguished from other species of Tropiocolotes by possessing weakly keeled dorsal scales and smooth ventral scales, having imbricate scales on dorsal and ventral tail, possessing clearly tricarinatesubdigital scales, 48–55 dorsal scales, two pairs of postmental shields, of which the second pair is about half of the size of the first, 100–107 scales longitudinally along underside of body, 15–19 scales across head and 16–19 subdigital lamellae.

Abstract This interview/dialogue addresses an important issue of how educational semiotics is grounded in the history of ideas. The discussions concern the shared history of semiotics and liberal education; the modern university and its medieval antecedents; semiotic consciousness, the traces of which are found in both Christianity and Islam (and the hermeneutics of Abrahamic and mystical religions, in general); intercultural translation; the relationship between learning (conceptualized edusemiotically) and biosemiotics, and how our social understandings of learning determine and shape our basic relationship to the world. Touching on the concepts of scaffolding and evolution, the chapter discusses adaptation in relation to learning, social semiotics and contemporary social reality, while imploring us to consider education in terms of its service to learning (and not the other way around).Campbell: This interview was originally published as a recorded podcast-interview in 2017, on philosophasters.org as part of the interview series Signs of Life. Thank you to Thomas Hoeller for recording and editing the sound and music, and Marion Benkaiouche for transcribing the interview. Thank you, Inna Semetsky, for summarizing the dialogue, included in part in the above abstract description. Please bear in mind that as this interview was conducted two years ago, the author´s current ideas on some of these topics may have changed.

AbstractThe Microgastrinae wasp Diolcogaster claritibia (Papp, 1959) (Hymenoptera: Braconidae), a parasitoid of the diamondback moth, Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae), is recorded from the Nearctic region (Alberta, Manitoba, and Ontario, Canada) for the first time. In spite of some minor morphological and molecular (DNA barcoding) differences, the available data indicate that the European and New World specimens should be considered one species, but more specimens and loci need to be sampled to conclusively determine the phylogeographic history of the species. Diolcogaster claritibia seems to be widely distributed within the Holarctic, and the molecular data suggest that it was recently introduced to North America from Europe.
