The south-eastern coast of Australia is recognised as a climate-change hotspot; warming over the past 50 years has exceeded the global average. The marine fauna in the region is responding to this warming with several subtidal species showing a pole-ward range expansion. We provide the first evidence for a similar response in intertidal invertebrates, on the basis of surveys from the eastern coast of Tasmania in 2007–2008 that replicated a set from the 1950s. Of 29 species used in the analysis, 55% were detected further south than in the 1950s. The average minimum movement of the southern (pole-ward) range edges was 116 km (range 20–250 km), representing a rate of ∼29 km per decade for a warming rate of 0.22°C per decade. Barnacles and gastropods showed the greatest range extensions, with one species absent from Tasmania in the 1950s, the giant rock barnacle, Austromegabalanus nigrescens, now recorded widely along the eastern coast of Tasmania. The distance that the southern (pole-ward) range limit moved south for each species was not related to a qualitative dispersal potential index. Local extinction of some species in north-eastern Tasmania may also occur in the coming decades.

This article shows the heuristic value of a film consumption study that combines oral archives and fieldwork with written sources. Oral archives on film consumption provided by a local film market of Longwy, an industrial town of north-eastern France, during the 1950s allow the researcher to reconstruct the audience’s collective experience of the films released on this market. Combined with a systematic study of local releases and their box office, they give us access to the artistic expertise of local filmgoers in the past and motivate us to challenge the conventional interpretation of film consumption as the ostensibly predictable expression of a social taste.

The paper describes the past and present distribution of Colchicum autumnale in the vicinity of Cracow, highlights the role of Stanisław Dembosz (who published the first locality of C. autumnale near Igołomia in 1841). Gives information about the occurrence of C. autumnale in Krzeszowice in the 19th century (reported by Bronisław Gustawicz), presents new localities noted in 2012–2014 in meadows in the north-eastern part of the Puszcza Niepołomicka forest and adjacent area (between the Vistula and Raba rivers), and gives a locality found in Cracow in 2005 (no longer extant).

AbstractAn initial investigation of recirculation is carried out for the coast of the Black Sea. The local mesoscale circulations (land-sea breezes, mountain and valley winds) in coastal areas are shown to be an additional risk factor in creating favorable conditions for air stagnation and accumulation of air pollutants in the surface atmosphere layer. Two types of annual recirculation patterns are revealed for northern and north-eastern coast of the Black Sea. Long-term changes in recirculation are investigated. It is shown that the recirculation parameter values remained quasistable until the mid-1970s. Since 1976–1977, steady intensification of recirculation in both winter and summer is identified.

The paper will establish a connection between folktales and the cultural history of a region, particularly with respect to the Indian state of Manipur. It is premised on the belief that a study of folktales can alert us not only to the various interconnections between folktales and the cultural history of a place but also help analyse the dynamics of the publication of the anthologies of folktales in relation to this cultural history. The paper will include analyses of Meitei and tribal tales pertaining to the nationalist phase and contemporary period in the history of the North Eastern Indian state of Manipur and look at how in the past few years, compilers and translators have incorporated versions of tales different from the earlier anthologies, establishing a direct link between the tales and the times of their publication.

Abstract The aim of this paper is to determine the trends of the main indicators of life expectancy in Russia in the 1950s to 2000s. For this purpose, life tables for Russia (former — RSFSR) from 1959 to 2014 for one-year age intervals were analyzed. The main indicators under review are the modal age at death and the standard deviation of life expectancy from the modal value for all ages and the mode. As a result, it is concluded that in Russia the modal age at death and the indicator of life expectancy have stagnated over the past 60 years, and definite trends can be traced only in short periods of time, namely after 2009 when all basic life expectancy indicators were steadily increasing. Life expectancy is far behind those of the developed countries by about half a century.

Two new fossiliferous amber outcrops in the heights of Baskinta and Bqaatouta (El-Maten and Kesserouan districts, Central Lebanon) are described. These new discoveries constitute respectively the 27th and 28th amber outcrops with biological inclusions in Lebanon, enrich and improve our knowledge about the palaeobiodiversity and palaeoenvironment of the North-Eastern coast of Gondwana during the early Barremian.

The northern Mandara Mountains of Cameroon have been a focus of slave raiding for the past five centuries, according to historical sources. Some captives from the area were enslaved locally, primarily in Wandala and Fulbe communities, while others were exported to Sahelian polities or further abroad. This chapter examines ethnohistorical and archaeological data on nineteenth- and twentieth-century slave raiding, derived from research in montagnard communities along the north-eastern Mandara Mountains of Cameroon. Enslavement and slave raiding existed within larger structures of day-to-day practice in the region, and were closely tied to ideas about sociality, social proximity and violence. Through the mid-1980s at least, enslavement in the region was understood as a still-relevant political and economic process, with its chief material consequence the intensely domesticated Mandara landscape.

During the past two years the commercial airline operators and the travelling public alike have been forced to acknowledge the rapid increase in airport congestion. This problem is most marked in the North Eastern area of America at the present time but a similar situation will develop fairly soon at major airports in Europe. Even with the introduction of the airbus to scheduled services, the number of aircraft movements at conventional airports, within a given time period, will reach a maximum safe level. The restrictions are imposed partly by the large number of aircraft operations on each runway, and partly by Air Traffic Control safety limits.
