Local Dispersal

Human mediated introductions of non-native species can pose a major threat to global biodiversity on several accounts i.e. through competition, the introduction of novel pathogens, and genetic pollution. Where hybridization occurs between two closely related species the F1 offspring are usually phenotypically discernible whereas F2 hybrid, backcrossed or admixed individuals become more difficult to separate. At this point the utilization of molecular methods is required in conservation efforts to differentiate and manage populations. This study demonstrated how a possible threat of hybridization from an introduced non-native (T. carnifex) with a protected native newt species (T. cristatus) could be investigated with molecular tools, and examined the current extent of its genetic introgression over an 80 years period. The results confirmed that hybridization had taken place at the site of introduction (and continues to do so), and that historically limited local dispersal of both non-natives and/or hybrids had occurred sometime in the past. However, the data suggests that although dispersal of hybrids into a local satellite site may still be occuring, hybridization with native species appears limited.

Past biological invasions have contributed to shaping our present day biodiversity. For many island ecosystems, they are the only source of terrestrial life. At the same time, biological invasions, in particular when caused by human activity, are a major concern for the conservation of native species. It is therefore essential to understand the drivers of biological invasions as well as the role invasions have played in different ecosystems. Molecular tools have provided valuable data to reconstruct biological invasions, their drivers, and their impacts. Recent technological developments have further increased the potential of molecular tools to track past shifts in biodiversity. Here, we provide a perspective on how such molecular tools have influenced our understanding of past biological invasions and discuss how they may further help to shape our understanding and management of biological invasions. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 52 is November 2021.

In this article I analyze how Americans draw upon the authority of both ancient, so-called “hidden” texts and the authority of scholarly discourse, even overtly fictional scholarly discourse, in their imaginings of the “re-discovered” figure of Mary Magdalene. Reading recent treatments of Mary Magdalene provides me with an entrance onto three topics: how Americans see and use the past, how Americans understand knowledge itself, and how Americans construct “religion” and “spirituality.” I do so through close studies of contemporary websites of communities that focus on Mary Magdalene, as well as examinations of relevant books, historical novels, reader reviews, and comic books. Focusing on Mary Magdalene alongside tropes of wisdom also uncovers the gendered dynamics at play in constructions of antiquity, knowledge, and religious accessibility.

It is an honour for me as President of the Pakistan Society of Development Economists to welcome you to the 13th Annual General Meeting and Conference of the Society. I consider it a great privilege to do so as this Meeting coincides with the Golden Jubilee celebrations of the state of Pakistan, a state which emerged on the map of the postwar world as a result of the Muslim freedom movement in the Indian Subcontinent. Fifty years to the date, we have been jubilant about it, and both as citizens of Pakistan and professionals in the social sciences we have also been thoughtful about it. We are trying to see what development has meant in Pakistan in the past half century. As there are so many dimensions that the subject has now come to have since its rather simplistic beginnings, we thought the Golden Jubilee of Pakistan to be an appropriate occasion for such stock-taking.

Other People’s Struggles is the first attempt in over forty years to explain the place of “conscience constituents” in social movements. Conscience constituents are people who participate in a movement but do not stand to benefit if it succeeds. Why do such people participate when they do not stand to benefit? Why are they sometimes present and sometimes absent in social movements? Why and when is their participation welcome to those who do stand to benefit, and why and when is it not? The work proposes an original theory to answer these questions, crossing discipline boundaries to draw on the findings of social psychology, philosophy, and normative political theory, in search of explanations of why people act altruistically and what it means to others when they do so. The theory is illustrated by examples from British history, including the antislavery movement, the women’s suffrage and liberation movements, labor and socialist movements, anticolonial movements, antipoverty movements, and movements for global justice. Other People’s Struggles also contributes to new debates concerning the rights and wrongs of “speaking for others.” Debates concerning the limits of solidarity—who can be an “ally” and on what terms—have become very topical in contemporary politics, especially in identity politics and in the new “populist” movements. The book provides a theoretical and empirical account of how these questions have been addressed in the past and how they might be framed today.

This chapter and the following both draw the reader into seventeenth-century understandings of the past, and of Boudica in particular, and makes clear that in a time before disciplines, writers of ‘history’ were erudite commentators, immersed in political thought, the classical world, and contemporary ideas, as well as in drama, poetry, and the law. Chapter 1 shows the subtleties of Boudica’s place in history at this early stage by giving sustained attention to the work of Edmund Bolton (1574/5–c.1634), the first person to analyse the written and material evidence for Boudica’s deeds, and the last to do so in depth before the later nineteenth century. Bolton’s distaste for contemporary philosophy and his loyalty to James I were highly influential in determining the way the antiquary approached Boudica and her rebellion; but equally important was Bolton’s deep understanding of historical method and the strictures this placed on his interpretive latitude.

AbstractTicks are vector arthropods responsible for the transmission of several pathogenic agents that affect both human and animal health worldwide. In this study our objective was to analyse, using molecular tools, the bacterial community of Dermacentor reticulatus and Haemaphysalis inermis ticks collected in south-eastern Slovakia. Using real-time PCR, we identified the presence of Rickettsia spp. DNA at levels of 14/59 (23.72 %) and 29/173 (16.76 %) in D. reticulatus and H. inermis, respectively. In addition, using standard PCR and sequencing, we identified the presence of Rickettsia raoultii DNA in 13 ticks belonging to the two investigated species. Rickettsia raoultii blast results revealed an average identification percentage of 99.62 %. Following the results of this molecular study there is a possibility that D. reticulatus and H. inermis play a potential role in the transmission of R. raoultii. To prove the possibility of validity of this hypothesis, we suggest performing experimental models in future studies. Our results can serve as preliminary data for future transmission models.

A striking feature of Palestinian oral history projects is the extensive use that interviewees make of direct speech to communicate their memories—especially those born before the 1948 Arab–Israeli war. They do so irrespective of whether or not they participated in or actually heard the dialogues they wish to convey. This article seeks to characterize and explain this phenomenon. In the interviews conducted by the author—an Arabic-speaking Jew—as well as in other projects, this mode of speech is marked by ease of transition from character to character and between different points in time. It clearly gives pleasure to those engaged in the act of remembering, and it grades readily into a theatrical performance in which tone of speech and the quality of the acting become the main thing. This form of discourse sprang up from the soil of a rural oral culture and still flourishes as a prop for supporting memory, a vessel for collecting and disseminating stories, and a technique for expressing identification with significant figures from the past.

In presenting my valedictory to this distinguished Association which has honored me by selecting me as its President, I should like to point out by way of introduction what has happened to this office, and therefore to me, during the past year. I have heard of one of my distinguished predecessors some twenty-five years ago who had little else to do as President of this Association than work all year on his presidential address. This was important work and I have no word of criticism of it. But the Association has changed, and today it leaves to the harried wearer of its presidential toga little time to reflect about the status of political science and his own impact, if any, upon it. An active Association life, now happily centered in our new Washington office, is enough to occupy the full time of your President, and universities as well as this Association might well take note. Therefore, in presenting my own reflections to you this evening in accordance with the custom of our Association, I do so without the benefit of the generous time and scholarly leisure which were the privileges of some of my distinguished predecessors.Nevertheless I do base my presidential address today upon my own active participation in the problems of government, as well as upon my scholarly experience. I have extracted it in part from the dynamics of pulsating political life. It has whatever authority I may possess after having been exposed these twenty-five years to the cross-fire of politics, domestic and foreign, as well as to the benign and corrective influences of eager students and charitable colleagues.

In the past few decades we have been improving our understanding of the weather system and exploring ways to modify it. Over sixty countries have experimented with modifying the weather. The new technology of weather and climate modification will raise important political problems which will demand new responses from the international community. Whether states will be able to establish the cooperative measures necessary to develop and manage new technology depends upon whether there are sufficient incentives to do so. This article analyzes the historical patterns of international cooperation in meteorology, and then plots against several time horizons projected developments and capabilities in weather modification technology and the potential problems emerging from using the technology. It derives a tentative picture of the responsibilities demanded, compares the likely responses with those needed, and assesses whether they will be adequate for the problems projected.

Denatured 3H-labelled DNAs containing Xenopus or human globin sequences hybridize to RNA transcripts on a single pair of lateral loops on lampbrush chromosome IX of Triturus cristatus carnifex, and to no other loops on this chromosome or the rest of the complement. However they do so, not because of the globin sequences in the probes, but rather because the plasmids from which the probes were prepared were constructed with G.C homopolymer tails. Simple sequence poly d(C/G)n probes also hybridize with RNA transcripts on this same pair of loops, and with no others.
