Management from the viewpoint of Lake Victoria fisheries

Fisheries science is concerned with ultimate yield prediction and control. The subject deals with the study of natural history of stocks and the dynamics of fish populations. The multiple species fisheries of Lake Victoria are undergoing rapid development. Already, some of the highly valued fish species have been reduced to very low population levels. The most abundant but less relished Haplochromis spp. remain underutilized. The real problem in management is to win acceptance for regulations that foster increasing productivity in the industry, without slavish adherence to status quo.

‘”Like an Old Cathedral City”: Belfast Welcomes Queen Victoria, August 1849’,

Belfast, with its history of communal violence, is normally seen as lying outside the mainstream of nineteenth-century British urban development. The visit of Queen Victoria in 1849 suggests a more complex, less linear picture. What emerges is an urban identity in transition, in which aspirations to conform to an ideal of civic harmony temporarily overrode acute sectarian and political divisions, where pride in recent economic achievement sat uneasily alongside an awareness of the town’s newcomer status, and where an emerging sense of regional difference competed with a continuing assumption of Irish identity.

Identifying appropriate sampling and modelling approaches for analysing distributional patterns of Antarctic terrestrial arthropods along the Victoria Land latitudinal gradient

Biotic communities in Antarctic terrestrial ecosystems are relatively simple and often lack higher trophic levels (e. g. predators); thus, it is often assumed that species' distributions are mainly affected by abiotic factors such as climatic conditions, which change with increasing latitude, altitude and/or distance from the coast. However, it is becoming increasingly apparent that factors other than geographical gradients affect the distribution of organisms with low dispersal capability such as the terrestrial arthropods. In Victoria Land (East Antarctica) the distribution of springtail (Collembola) and mite (Acari) species vary at scales that range from a few square centimetres to regional and continental. Different species show different scales of variation that relate to factors such as local geological and glaciological history, and biotic interactions, but only weakly with latitudinal/altitudinal gradients. Here, we review the relevant literature and outline more appropriate sampling designs as well as suitable modelling techniques (e. g. linear mixed models and eigenvector mapping), that will more adequately address and identify the range of factors responsible for the distribution of terrestrial arthropods in Antarctica.

The Victoria Falls 1900-1940: Landscape, tourism and the geographical imagination

This article is about the politics of landscape ideas, and the relationship between landscape, identity and memory. It explores these themes through the history of the Victoria Falls, and the tourist resort that developed around the waterfall after 1900. Drawing on oral and archival sources, including popular natural history writing and tourist guides, it investigates African and European ideas about the waterfall, and the ways that these interacted and changed in the course of colonial appropriations of the Falls area. The tourist experience of the resort and the landscape ideas promoted through it were linked to Edwardian notions of Britishness and empire, ideas of whiteness and settler identities that transcended new colonial borders, and to the subject identities accommodated or excluded. Cultures of colonial authority did not develop by simply overriding local ideas, they involved fusions, exchanges and selective appropriations of them. The two main African groups I am concerned with here are the Leya, who lived in small groups around the Falls under a number of separate chiefs, and the powerful Lozi rulers, to whom they paid tribute in the nineteenth century. The article highlights colonial authorities' celebration of aspects of the Lozi aristocracy's relationship with the river, and their exclusion of the Leya people who had a longer and closer relationship with the waterfall. It also touches on the politics of recent attempts to reverse this exclusion, and the controversial rewriting of history this has involved.

A Glacial Geomorphological Map of Victoria Island, Canadian Arctic

Victoria Island lies at the north-western extremity of the region covered by the vast North American Laurentide Ice Sheet (LIS) in the Canadian Arctic Archipelago. This area is significant because it linked the interior of the LIS to the Arctic Ocean, probably via a number of ice streams. Victoria Island, however, exhibits a remarkably complex glacial landscape, with several successive generations of ice flow indicators superimposed on top of each other and often at abrupt (90 degrees) angles. This complexity represents a major challenge to those attempting to produce a detailed reconstruction of the glacial history of the region. This paper presents a map of the glacial geomorphology of Victoria Island. The map is based on analysis of Landsat Enhanced Thematic Plus (ETM+) satellite imagery and contains over 58,000 individual glacial features which include: glacial lineations, moraines (terminal, lateral, subglacial shear margin), hummocky moraine, ribbed moraine, eskers, glaciofluvial deposits, large meltwater channels, and raised shorelines. The glacial features reveal marked changes in ice flow direction and vigour over time. Moreover, the glacial geomorphology indicates a non-steady withdrawal of ice during deglaciation, with rapidly flowing ice streams focussed into the inter-island troughs and several successively younger flow patterns superimposed on older ones. It is hoped that detailed analysis of this map will lead to an improved reconstruction of the glacial history of this area which will provide other important insights, for example, with respect to the interactions between ice streaming, deglaciation and Arctic Ocean meltwater events.

Victoria en Germania. Tomás Luis de Victoria y la historiografía alemana hasta principios del siglo XX

Es war bisher unbekannt, dass die deutschsprachige Musikhistoriographie dem Komponisten Tomás Luis de Victoria relativ viel Beachtung geschenkt hat. Als iberischer Counterpart des Heroen Palestrina spielt er bei der Gestaltung eines Geschichtsbildes der musikalischen Renaissance daher eine viel wichtigere Rolle als bisher vermutet. Die Auseinandersetzung deutscher Musikwissenschaftler mit Victoria spielte eine zentrale Rolle bei der Würdigung des Komponisten durch die spanische Historiographie.

Antarctic Glacial History Since the Last Glacial Maximum: An Overview of the Record on Land

This overview examines available circum-Antarctic glacial history archives on land, related to developments after the Last Glacial Maximum (LGM). It considers the glacial-stratigraphic and morphologic records and also biostratigraphical information from moss banks, lake sediments and penguin rookeries, with some reference to relevant glacial marine records. It is concluded that Holocene environmental development in Antarctica differed from that in the Northern Hemisphere. The initial deglaciation of the shelf areas surrounding Antarctica took place before 10000 C-14 yrs before present(sp), and was controlled by rising global sea level. This was followed by the deglaciation of some presently ice-free inner shelf and land areas between 10000 and 8000 yr sp. Continued deglaciation occurred gradually between 8000 yr sp and 5000 yr sp. Mid-Holocene glacial readvances are recorded from various sites around Antarctica. There are strong indications of a circum-Antarctic climate warmer than today 4700-2000 yr sp. The best dated records from the Antarctic Peninsula and coastal Victoria Land suggest climatic optimums there from 4000-3000 yr sp and 3600-2600 yr sp, respectively. Thereafter Neoglacial readvances are recorded. Relatively limited glacial expansions in Antarctica during the past few hundred years correlate with the Little Ice Age in the Northern Hemisphere.

Delfina Bunge. Victoria Ocampo hacedoras de un espacio literario 1920-1940

Los teóricos de la literatura han propuesto una serie de conceptos específicos para estudiar la problematización del hecho literario. Unido a esto la noción de "espacio literario" aparece como búsqueda de la esencia de la literatura y de un campo donde se asiente la intimidad del yo. A partir de esta categoría y su asociación con el concepto de mentalidad, entendida como forma de pensar que se sucede a lo largo de la historia donde se plasman códigos de vida, en el presente trabajo se analizan dos ensayos sobre la problemática femenina y su inserción en el espacio intelectual de su época. El estudio de los ensayos de Delfina Bunge Las mujeres y su vocación y La mujer y su expresión de Victoria Ocampo pretende destacar la búsqueda de un espacio literario femenino propio centrando el interés particularmente en la problemática de la emancipación de la mujer. Los dos textos se articulan sobre algunos ejes temáticos comunes que permiten establecer coincidencias en el pensamiento de estas escritoras argentinas respecto de la maternidad, la educación y la igualdad respecto del varón.
