The 1960S

We examined published historical information, reports on aerial surveys conducted since 1953, and harvest data collected since 1971 to describe changes in the distribution and abundance of Caribou (Rangifer tarandus) in Québec. The southern limit of the Caribou distribution diminished considerably in the late 19th century, and the decline in numbers probably continued until the 1960s and 1970s east of the 62nd meridian. South of the 49th parallel, only four small populations still persist. Despite the fact that all Caribou of the province were assigned to the same sub-species (R. t. caribou), three ecotypes with specific habitats and behaviour are found. The Barren-Ground ecotype, the only migratory form, is found north of the 52nd parallel. This ecotype currently occupies ≈ 255 000 km2 in fall and winter, mainly in the ecological subzones of the forest tundra and the taiga. The Barren-Ground Caribou was characterized by a very low abundance from the end of the 19th century until the mid-1950s, but increased markedly thereafter reaching over a million individuals at the beginning of the 1990s. Populations of the Mountain ecotype have been identified in the southeastern and, possibly, in the northeastern parts of the province. The latter Mountain population is virtually unknown. The southeastern population is sedentary and uses mainly the boreal forest. This population has decreased over the last century and currently numbers only ≈ 140 individuals. Finally, the Forest-Dwelling ecotype is found discontinuously, mainly between the 49th and 55th parallels. Its current distribution covers ≈ 235 000 km2, mainly east of the 72nd meridian. This sedentary ecotype is found almost exclusively in the boreal forest, principally in areas with long forest fire cycles. Its abundance has also decreased over the years. Large Forest-Dwelling populations still persisted during the 1950s and 1960s, but they apparently disappeared. The current abundance is not known precisely, but based on density estimates and considering the current distribution, it probably does not exceed 3000 individuals. Current data are insufficient to identify precisely the causes of the population decline, although hunting seems to be an important proximal cause.Nous avons utilisé les données historiques publiées, les rapports d’inventaires aériens réalisés depuis 1953 et les statistiques de récolte sportive colligées depuis 1971 pour décrire les changements dans la répartition et l’abondance du Caribou (Rangifer tarandus) au Québec. La limite méridionale de l’aire de répartition a beaucoup diminué à la fin du 19e siècle et la régression s’est probablement poursuivie durant les années 1960 et 1970 à l’est du 62e méridien. Au sud du 49e parallèle, on ne retrouve plus que quatre petites populations. Bien que tous les caribous du Québec soient considérés appartenir à la même sous-espèce (R. t. caribou), on distingue trois écotypes fréquentant des milieux différents et arborant des comportements spécifiques. Au nord du 52e parallèle, on retrouve l’écotype Toundrique, lequel est migrateur. Ces Caribous se répartissent sur ≈ 255 000 km2 durant l’automne et l’hiver, principalement dans les sous-zones écologiques de la toundra forestière et de la taïga. Cet écotype était peu abondant entre la fin du 19e siècle et le milieu des années 1950, mais il s’est accru considérablement pour atteindre plus d’un million d’individus au début des années 1990. Une population de l’écotype Montagnard est présente au sud-est de la province et une autre existe possiblement au nord-est. Cette dernière n’est pas bien connue. Celle du sud-est utilise principalement la forêt boréale. Cette population sédentaire a diminué considérablement depuis une centaine d’années et elle ne compte plus qu’environ 140 individus. Finalement, l’écotype Forestier est présent de façon discontinue, principalement entre les 49e et 55e parallèles. Ces Caribous sont également sédentaires. On les retrouve presque exclusivement en forêt boréale, principalement là où le cycle des feux de forêt est long. Leur répartition actuelle couvre ≈ 234 000 km2, principalement à l’est du 72e méridien. D’importantes populations forestières existaient encore durant les années 1950 et 1960, mais elles semblent avoir disparu. L’abondance actuelle n’est pas connue mais elle pourrait difficilement dépasser 3000 individus si l’on se base sur les estimations de la densité et de l’aire de répartition. Les données disponibles sont insuffisantes pour identifier les causes exactes des diminutions d’effectifs bien que la chasse semble une cause proximale importante.

Evidence for the fidelity of female barren-ground caribou (Rangifer tarandus spp.) of each herd to specific calving grounds is convincing. Involvement of learned behaviour in the annual return of those cows to the same calving grounds implies such actions are a form of «traditional» behaviour. Even wide variations in population size have not yet knowingly led to marked changes in size or location of calving grounds or prolonged abandonment of established ones. Rarely is the adoption of new calving grounds reported and emigration to another herd's calving ground or interchange between calving grounds has not yet been unequivocally documented. The calving experience of individual caribou and environmental pressures may modify the cow's use patterns of her calving grounds. The current definition of herds based on traditional calving grounds may require modification, if increasing caribou numbers result in changes in traditions. However, current data do not contradict either the fidelity to traditional calving grounds or the concept of herd identity based on that fidelity.

The 1960S

The Chernobyl accidenr of 1986 caused radioactive contamination of widespread areas of reindeer pasture in Scandinavia. Reindeer {Rangifer tarandus) are especially exposed to radioactive fallout due to their wintet diet, of which lichens are an important part. Much knowledge about the transfer of radiocaesium to reindeer, and via reindeer meat to man, was accumulated by intense scientific investigations, undertaken during the 1960s and 1970s, following nuclear weapons testing. Various ways to reduce the transfer of radiocaesium to animals and humans were also developed during this time. Much of the older knowledge proved to be of great value in the attempts to determine potential consequences of the Chernobyl accident and to suggest possible ways to ameliorate the effects of contamination. After Chernobyl, not only did reindeer prove to be a problem; many other food products originating ftom natural and semi-natural ecosystems were found to accumulate significant amounts of radiocaesium. Intense scientific work has produced new knowledge about the role of ungulates in the transfer of nutrients and contaminants within these systems. Different measures, like providing uncontaminated feed, use of caesium binders, altering the time of slaughter have been used with good results to minimize the transfer of radiocaesium to animals grazing natural pastures. The high cost of countermeasures has enforced consideration of cost against risk, which may also be of general interest with respect to other forms of pollution. Information, introduction of countermeasures and so forth would be more efficient in case a similar accident were to happen again. The Chernobyl accident is an obvious example of how human failures when dealing with a modern technical system can have global consequences and also be a potential threat to what we like to think of as the unspoiled wilderness of the Arctic.

Palaeolimnological techniques were used to study the recent acidification history of Lilia Oresjon in southwest Sweden, and its relation to the deposition of airborne pollutants and land-use. The sediment analyses suggest that water quality began to deteriorate at the beginning of the 20th century and resulted in an acute acidification phase in the 1960s. An indifferent (circumneutral) diatom flora with some planktonic taxa was replaced by a non-planktonic acidophilous and acidobiontic flora; diatom inferred pH decreased from 6.1 in the 19th century to the present value of about 4.6. The history of acidification and of major biological change in the lake is reinforced by the analyses of chrysophyte scales and cladocera and chironomid remains, which show that alterations of species composition and an impoverishment of faunal communities took place. There is close stratigraphic agreement between these biological changes and indicators of the deposition of atmospheric pollutants. The concentration of Pb, Zn, Cu and S increased from the beginning of the 19th century to peak values during the 1960s and 1970s. Spheroidal carbonaceous particles, polycyclic aromatic hydrocarbons (PAH) and ‘hard’ isothermal remanence, indicative of oil and coal combustion, peaked during the 1970s and 1980s, respectively. The increased deposition of airborne pollutants from fossil fuel combustion and industrial processes is suggested as the main cause of the acidification of the lake, although vegetation changes, such as a recent expansion of spruce-pine forest, have also occurred during the 200—300 year period studied.

Deepwater ciscoes (Coregonus spp.) or "chubs" of Lake Michigan far surpassed those of Lake Huron in yield, population density, and resilience following severe depletion in the 1960s and 1970s, when the bloater (C. hoyi) composed more than 90% of the stocks. The population decline of bloaters in recent decades was mainly attributed to exploitation, to the depression of chub recruitment (e.g. from inferred predation on early life stages) by nonendemic alewives (Alosa pseudoharengus) and rainbow smelt (Osmerus mordax), and to complications arising from extreme female predominance that was best documented for Lake Michigan. The various interactions between bloaters and the nonendemic species, which were intensified after the loss of large predators to sea lamprey (Petromyzon marinus), would help to explain why a stock–recruitment relation was not shown for the Lake Michigan bloater. We hypothesize that reproductive inefficiency caused by a shift to strong female predominance in the bloater depresses recruitment and thus helps to regulate abundance. However, the low resilience that sex imbalance seems to impart makes the stock unstable when exploited. It should therefore be exploited conservatively during such periods. Also, the sex ratio and its direction of change appear to be important qualifiers when surplus production is estimated from stock size.

This article traces Ken Russell's explorations of war and wartime experience over the course of his career. In particular, it argues that Russell's scattered attempts at coming to terms with war, the rise of fascism and memorialisation are best understood in terms of a combination of Russell's own tastes and personal style, wider stylistic and thematic trends in Euro-American cinema during the 1960s and 1970s, and discourses of collective national experience. In addition to identifying Russell's recurrent techniques, this article focuses on how the residual impacts of the First and Second World Wars appear in his favoured genres: literary adaptations and composer biopics. Although the article looks for patterns and similarities in Russell's war output, it differentiates between his First and Second World War films by indicating how he engages with, and temporarily inhabits, the stylistic regime of the enemy within the latter group.

Brainwashing assumed the proportions of a cultural fantasy during the Cold War period. The article examines the various political, scientific and cultural contexts of brainwashing, and proceeds to a consideration of the place of mind control in British spy dramas made for cinema and television in the 1960s and 1970s. Particular attention is given to the films The Mind Benders (1963) and The Ipcress File (1965), and to the television dramas Man in a Suitcase (1967–8), The Prisoner (1967–8) and Callan (1967–81), which gave expression to the anxieties surrounding thought-control. Attention is given to the scientific background to the representations of brainwashing, and the significance of spy scandals, treasons and treacheries as a distinct context to the appearance of brainwashing on British screens.

The Impact

This article reports findings of research into the far-reaching plan to ‘modernise’ the Scottish economy, which emerged from the mid-late 1950s and was formally adopted by government in the early 1960s. It shows the growing awareness amongst policy-makers from the mid-1960s as to the profoundly deleterious effects the implementation of the plan was having on Glasgow. By 1971 these effects were understood to be substantial with likely severe consequences for the future. Nonetheless, there was no proportionate adjustment to the regional policy which was creating these understood ‘unwanted’ outcomes, even when such was proposed by the Secretary of State for Scotland. After presenting these findings, the paper offers some consideration as to their relevance to the task of accounting for Glasgow's ‘excess mortality’. It is suggested that regional policy can be seen to have contributed to the accumulation of ‘vulnerabilities’, particularly in Glasgow but also more widely in Scotland, during the 1960s and 1970s, and that the impact of the post-1979 UK government policy agenda on these vulnerabilities is likely to have been salient in the increase in ‘excess mortality’ evident in subsequent years.

The Relationship

The mid-1960s saw the beginnings of the construction of a Palestinian political field after it collapsed in 1948, when, with the British government’s support of the Zionist movement, which succeeded in establishing the state of Israel, the Palestinian national movement was crushed. This article focuses mainly on the Palestinian political field as it developed in the 1960s and 1970s, the beginnings of its fragmentation in the 1990s, and its almost complete collapse in the first decade of this century. It was developed on a structure characterized by the dominance of a center where the political leadership functioned. The center, however, was established outside historic Palestine. This paper examines the components and dynamics of the relationship between the center and the peripheries, and the causes of the decline of this center and its eventual disappearance, leaving the constituents of the Palestinian people under local political leadership following the collapse of the national representation institutions, that is, the political, organizational, military, cultural institutions and sectorial organizations (women, workers, students, etc.) that made up the PLO and its frameworks. The paper suggests that the decline of the political field as a national field does not mean the disintegration of the cultural field. There are, in fact, indications that the cultural field has a new vitality that deserves much more attention than it is currently assigned.

This essay focuses on a body of photoconceptual works from the 1960s and 1970s in which the automobile functions as a prosthetic-like aperture through which to view the world in motion. I argue that the logic of the “automotive prosthetic“ in works by Paul McCarthy, Dennis Hopper, Ed Ruscha, Jeff Wall, John Baldessari, Richard Prince, Martha Rosler, Robert Smithson, Ed Kienholz, Julian Opie, and Cory Arcangel reveals a techno-genetic understanding of conceptual art, functioning in addition and alternatively to semiotics and various philosophies of language usually associated with conceptual art. These artworks show how the automobile, movement on roads and highways, and the automotive landscape of urban sprawl have transformed the human sensorium. I surmise that the car has become a prosthetic of the human body and is a technological force in the maieusis of the posthuman subject. I offer a reading of specific works of photoconceptual art based on experience, perception, and a posthumanist subjectivity in contrast to solely understanding them according to semiotics and linguistics.
