Uruguay River

The Uruguay River basin in South America has held a social, cultural, environmental, and economic relevance for many centuries. The river flows for about 2,000 km, linked to an important remnant of native forest, the Selva Misionera in Argentina, and to a Brazilian conservation unit for biodiversity, the Turvo State Park. The Uruguay River is fed by several other important rivers, forming a basin region in which thousands of people live and work. The history of the Uruguay River is intensively linked to the permeable borders between Brazil, Argentina, and Uruguay where different social groups circulated in diverse historical time periods. Forests along the river played a very important role with emphasis on the extraction and trade of yerba mate (Ilex paraguariensis, Saint-Hilaire), a forest product widely consumed in southern America, and also the timber extraction from native forests, during the nineteenth and twentieth centuries. As a result, a profound socio-environmental transformation took place with the reconstruction of regional landscapes shaped by the Uruguay River basin.

Abstract Astyanax is a species-rich, non-monophyletic genus composed of several supraspecific taxa that are poorly delimited. The Astyanax fasciatus complex is one of these taxa and shows high taxonomic complexity. To elucidate the evolutionary history of the A. fasciatus complex from southern South America, we conducted cytogenetic, molecular and morphological analyses in specimens from the Uruguay River basin. Cytogenetic characters demonstrated two closely related operational taxonomic units: Astyanax sp. 1 (8m+22sm+10st+6a), Astyanax sp. 2 (8m+24sm+10st+4a) and natural hybrids (8m+23sm+8st+5a). 5S ribosomal DNA sites were found in two pairs of m chromosomes and one pair of a chromosomes in Astyanax sp. 1, two pairs of a chromosomes and one pair of m chromosomes in Astyanax sp. 2, and three m chromosomes and three a chromosomes in hybrids. As51 sites were found in three chromosomes in Astyanax sp. 1 and in five chromosomes in Astyanax sp. 2 and hybrids. Mitochondrial sequence analyses did not separate the two units and hybrids. Morphological analyses revealed differences between Astyanax sp. 2 and hybrids. This secondary contact with gene flow between lineages that diverged long ago might slow or reverse the differentiation/speciation process. These results help us to understand the evolutionary history of this highly complex clade of Astyanax in southern South America.

History Of

Charles Waterton was the eccentric “Lord of Walton Hall” near Wakefield in Yorkshire. His Wanderings in South America was first published in 1826; translated into French, German and Spanish, it was a best seller. He brought back wourali used by the Macoushi natives of British Guiana (now Guyana) for killing prey; there is a piece of it in the Wakefield Museum. This paper traces the history of wourali which paralyses its victims; its attempted medical use for rabies and tetanus and, though different from curare, its belated use in modern anaesthesia.

John Owen Havard, “‘What Freedom?’: Frankenstein, Anti-Occidentalism, and English Liberty” (pp. 305–331) “If he were vanquished,” Victor Frankenstein states of his monstrous creation in Mary Shelley’s Frankenstein (1818), “I should be a free man.” But he goes on: “Alas! what freedom? such as the peasant enjoys when his family have been massacred before his eyes, his cottage burnt, his lands laid waste, and he is turned adrift, homeless, pennyless, and alone, but free.” Victor’s circumstances approximate the deracinated subject of an emergent economic liberalism, while looking to other destitute and shipwrecked heroes. Yet the ironic “freedom” described here carries an added charge, which Victor underscores when he concludes this account of his ravaged condition: “Such would be my liberty.” This essay revisits the geographic plotting of Frankenstein: the digression to the East in the nested “harem” episode, the voyage to England, the neglected episode of Victor’s imprisonment in Ireland, and the creature’s desire to live in South America. Locating Victor’s concluding appeal to his “free” condition within the novel’s expansive geography amplifies the political stakes of his downfall, calling attention to not only his own suffering but the wider trail of destruction left in his wake. Where existing critical accounts have emphasized the French Revolution and its violent aftermath, this obscures the novel’s pointed critique of a deep and tangled history of English liberty and its destructive legacies. Reexamining the novel’s geography in tandem with its use of form similarly allows us to rethink the overarching narrative design of Frankenstein, in ways that disrupt, if not more radically dislocate, existing rigid ways of thinking about the novel.

Nineteenth And Twentieth Centuries

During the nineteenth and twentieth centuries, the global Mennonite church developed an uneasy relationship with Germany. Despite the religion's origins in the Swiss and Dutch Reformation, as well as its longstanding pacifism, tens of thousands of members embraced militarist German nationalism. This book is a sweeping history of this encounter and the debates it sparked among parliaments, dictatorships, and congregations across Eurasia and the Americas. Offering a multifaceted perspective on nationalism's emergence in Europe and around the world, the book demonstrates how Mennonites' nationalization reflected and reshaped their faith convictions. While some church leaders modified German identity along Mennonite lines, others appropriated nationalism wholesale, advocating a specifically Mennonite version of nationhood. Examining sources from Poland to Paraguay, the book shows how patriotic loyalties rose and fell with religious affiliation. Individuals might claim to be German at one moment but Mennonite the next. Some external parties encouraged separatism, as when the Weimar Republic helped establish an autonomous “Mennonite State” in Latin America. Still others treated Mennonites as quintessentially German; under Hitler's Third Reich, entire colonies benefited from racial warfare and genocide in Nazi-occupied Ukraine. Whether choosing Germany as a national homeland or identifying as a chosen people, called and elected by God, Mennonites committed to collective action in ways that were intricate, fluid, and always surprising.

Basin Area

India is a subcontinent, there huge no of people lived in river basin area. In India there more or less 80% of people directly or indirectly depend on River. Ganga, Brahamputra in North and North East and Mahanadi, Govabori, Krishna, Kaveri, Narmoda, Tapti, Mahi in South are the major river basin in India. There each year due to flood and high tide lots of people are suffered in river basin region in India. These problems destroy the socio economic peace and hope of the people in river basin. There peoples are continuously suffered by lots of difficulties in sort or in long term basis. Few basin regions are always in high alert at the time of monsoon seasons. Sometime due to over migration from basin area, it becomes empty and creates an ultimate loss of resources in India and causes a dis-balance situation in this area.
