Bats have evolved migration to escape unfavourable climatic conditions. However, their migratory flyways and the way how they surmount geographical barriers are still unknown. The Jungfraujoch in the Swiss Alps is a mountain covered in permafrost (3460m ASL), known colloquially as the “Top of Europe”. Using broadband ultrasound recorders, we tested the occurrence of bats at the high altitude research station. In 36 nights, we recorded 268 bat call sequences of 8 species, including all European long-distance migrant bats. Since no feeding buzzes were recorded, we assume the bats were on transit. This is the first evidence to show that migrating bats can fly at unprecedented altitudes to cross the Alps. This feat outperforms the spectacular behaviour of the high altitude foraging bat Tadarida brasiliensis. Our findings shed light on the bats’ migratory flyways and demonstrate that the field of aeroecology can still uncover unexpected perspectives on the behaviour of bats.

AbstractThe thermal regime of high-altitude accumulation areas in the Swiss Alps was systematically investigated on the Jungfraufirn, Bernese Alps, on the Breithornplateau, Valais Alps, and on Grenzgletscher, Valais Alps. In 1991, 1992 and 1994, temperatures were measured in a deep hole (120 m deep) and in several shallow holes (14–30 m deep). Whereas the wide névé of the Jungfraufirn at 3400–3600 m a.s.l. and the 3800 m high Breithornplateau seems to be predominantly temperate, cold firn and ice temperatures were measured throughout on Grenzgletscher (3900–4450 m a.s.l.). Mean firn temperatures on Grenzgletscher vary strongly and range between −3° and −14°C. A comparison between the measured temperature profiles and a one-dimensional heat-conduction calculation shows that the release of latent heat by penetrating and refreezing meltwater decisively influences the thermal pattern of the firn pack. A multiple linear regression model, based on measured firn temperatures from the European Alps and the parameters altitude and aspect, yields aspect-dependent lower boundaries for the occurrence of cold firn ranging between 3400 (northerly aspects) and 4150 m a.s.l. (southerly aspects). A total of 120 glaciers with cold-firn areas are found when applying the model to glacier inventory data from the European Alps.

This paper examines the inherent intermediary realities of design-build within a continuum of academia and practice through the presentation of a series of “in-betweens” associated with a year-long design-build studio, a mobile shelter and research station for the Sharjah Environment and Protected Areas Authority (EPAA) sited within the extreme climatic conditions of the Arabian Desert. It analyzes a set of liminal, cultural, and environmental conditions and how they defined the design process; the way in which we engaged the community; and the resulting architecture as an assessment of the studio experience from the conceptual through to the deployment of built work. The impetus for the studio was a fascination with the Empty Quarter of the Rub’ al Khali, one of the most isolated places on Earth and until recently referred to as “terra incognita”, and the intersection between the disappearing Bedouin culture and the rapidly developing and modernizing culture of the United Arab Emirates. For thousands of years, the Bedouins have traversed the Arabian deserts and are the only masters of their more than 650,000 square kilometers of ancient sands. The first foreign explorers were not able to penetrate the Quarter until 1931, with the first accurate Western maps made by Thesiger between 1946 and 1950. Since then, only a few extreme adventurers have attempted its crossing, leaving the rest of us to wonder at its edge.

The philosophical and political aspects of Utopia have often shadowed the geographical and cartographical dimension of More’s work. Thus, I will try to shed light on this aspect of the book in order to lay emphasis on the links fostered between knowledge and space during the Renaissance. I shall try to show how More’s opusculum aureum, which is fraught with cartographical references, reifies what Germain Marc’hadour terms a “fictional archipelago” (“The Catalan World Atlas” (c. 1375) by Abraham Cresques ; Zuane Pizzigano’s portolano chart (1423); Martin Benhaim’s globe (1492); Martin Waldseemüller’s Cosmographiae Introductio (1507); Claudius Ptolemy’s Geographia (1513) ; Benedetto Bordone’s Isolario (1528) ; Diogo Ribeiro’s world map (1529) ; the Grand Insulaire et Pilotage (c.1586) by André Thevet). I will, therefore, uncover the narrative strategies used by Thomas More in a text which lies on a complex network of geographical and cartographical references. Finally, I will examine the way in which the frontispiece of the editio princeps of 1516, as well as the frontispiece of the third edition published by Froben at Basle in 1518, clearly highlight the geographical and cartographical aspect of More’s narrative.

In the summer of 1962 at the White Mountain Research Station the early phases of altitude acclimatization were studied in six of the surviving eight members of the 1935 expedition to the Chilean Andes; they were from 58 to 71 years of age. Alveolar and arterial Po2 and Pco2 were determined for each man a few hours after arrival at 3,093 m and at 3,800 and 4,343 m over the next few days. The effects of age were superimposed on the classical responses to high altitude. The arterial and alveolar Pco2 values showed no significant gradient; the alveolar Pco2 was found to be lower for a given altitude than 27 years before. For example, their average alveolar Pco2 at 4,700 m in 1935 was 27.7 mm Hg as opposed to 25.1 mm Hg at 4,343 m in 1962. The case of Hall was exceptional: his alveolar Pco2 ranged from 21 to 24 mm Hg regardless of altitude for his sojourn of 22 days. In 1935 these six men had a mean A-a Po2 gradient of +3.0 mm Hg at 4,700 m, while in 1962 the gradient over the three altitudes was +12.4 mm Hg. These findings would likely be explained partially by age changes in the pulmonary ventilation-perfusion ratio. acclimatization; pulmonary ventilation-perfusion ratio; alveolar-arterial Po2 and Pco2 gradients; alveolar hyperventilation; aging and altitude Submitted on February 19, 1963

AbstractNumerous studies have dealt with the process of globalization and its various cultural products. Three such cultural products illustrate this process: Vikas Swarup’s novel Q and A (2005), the TV quiz show Kaun banega crorepati? (Who Wants to Be a Millionaire?), and Danny Boyle’s film Slumdog Millionaire (2008). The novel, the TV show and the film have so far been studied separately. Juxtaposing and comparing Q and A, Kaun banega crorepati, and Slumdog Millionaire provides an effective means to shed light on the dialogic and interactive nature of the process of globalization. It is argued through this case study that an analysis of their place of production, language and content, helps clarify the derivative concepts of “glocalization” and “grobalization” with regard to the way(s) contemporary cultural products respond to globalization.

Abstract. In the present pilot study, an optimized LOPAP instrument (LOng Path Absorption Photometer) for the detection of nitrous acid (HONO) in the atmosphere (DL 0.2 pptV) was tested at the high alpine research station Jungfraujoch at 3580 m altitude in the Swiss Alps under conditions comparable to polar regions. HONO concentrations in the range <0.5–50 pptV with an average of 7.5 pptV were observed at the Jungfraujoch. The diurnal profiles obtained exhibited clear maxima at noon and minima with very low concentration during the night supporting the proposed photochemical production of HONO. In good agreement with recent measurements at the South Pole, it was demonstrated, that interferences of chemical HONO instruments can significantly influence the measurements and lead to considerable overestimations, especially for low pollution level. Accordingly, the active correction of interferences is of paramount importance for the determination of reliable HONO data.

Fragmentation of land and buildings was common in the Alps due to the nature of the interplay between economy and ecology. A fragmented holding allowed a farmer to spread his agricultural labor evenly throughout the season, while at the same time protecting him against the everpresent dangers of avalanche and flooding. Following the second world war, with a shift from agriculture to industry as the basis of the rural alpine economy, fragmentation came to be more of a nuisance than a necessity. Finally, with the introduction of tourism, new uses for land, particularly for house sites, rendered fragmentation totally useless. Yet the practice continues, deeply ingrained in the conservative rural tradition.
