AbstractSix serpentinites occur in the Moinian granulites of the North-East Ox Mountains. Four have been known for some time and have been previously described. Additional information on these and the associated vermiculite deposits is provided. The remaining two serpentinites are described for the first time. A pyroxenite vein associated with one of these may have been produced by meta-morphic regeneration.The relationship of some of these serpentinites to the probable position of the Highland Boundary Fracture-zone in Eire is also discussed. Brief comparison is made with serpentinites occurring in the Scottish Moinian.

Впервые в мире создана популяция зубров на территории 60 градусов северной широты. В новых климатических условиях разведения и сохранения зубров определены и проанализированы факторы существования вида на севере Европейской части РФ. Выявлены признаки, динамика численности, которые являются составной частью системы, предназначенной для управления биоразнообразием. Интродукция, являясь процессом введения в экосистему нехарактерных для нее видов, может усиливать изменения биоценозов как положительно, так и отрицательно. Насколько быстро и успешно проходит процесс адаптации заселенного вида, и усматривается его влияние на окружающую среду зависит дальнейшее существование зубров и в целом биоразнообразия. В статье обсуждаются вопросы взаимоотношения зубров с другими видами копытных и хозяйственной деятельностью человека, а также дальнейшим использованием зубров в сельскохозяйственном производстве. Пластичность зубров, выявление изменений и их анализ при вселении видов в новые условия обитания необходимы не только для определения развития или деградации биоценозов и в целом экосистемы, но и прогноза социально-экономических последствий интродукции как одного из методов сохранения редких и исчезающих видов фауны.For the first time in the world, a bison population has been created in an area of 60 degrees north latitude. In the new climatic conditions of breeding and preservation of bison, the factors of the species existence in the north of the European part of the Russian Federation are identified and analyzed. The signs, dynamics of abundance, which are an integral part of the system designed to manage biodiversity are identified, since the preservation of biological diversity on the planet is one of the main problems of our time. Introduction, being the process of introducing non-typical species into an ecosystem, can enhance changes in biocenoses, both positively and negatively. The question posing sounds especially when it comes to such a large hoofed animal as the European bison. How quickly and successfully the process of adaptation of the universe takes place and its environmental impact is seen depends on the continued existence of bison and biodiversity in general. The article discusses the relationship of bison with other types of ungulates and human activities, as well as the further use of bison in agricultural production. How these issues will be resolved positively depends on the future of these animals. Thus, the plasticity of bison, the identification of changes and their analysis, with the introduction of species into new habitat conditions is necessary not only to determine the development or degradation of biocenoses and the ecosystem as a whole, but also to predict the socio-economic consequences due to the introduction as one of the methods of preserving rare and endangered species of fauna.

AbstractIn 1789 in Leipzig, a slim pamphlet of 128 pages appeared that sent shock waves through the German republic of letters. The pamphlet, bearing the title Mehr Noten als Text (More notes than text), was an ‘exposure’ whose most sensational element was a list naming numerous members of the North German intelligentsia as initiates of a secret society. This secret society, known as the German Union, aimed to push back against anti-Enlightenment tendencies most obviously manifest in the policies promulgated under the new Prussian king Frederick William II. The German Union was the brainchild of the notorious theologian Carl Friedrich Bahrdt (1741–92). But who was responsible for the ‘exposure’? Using material culled from several archives, this article pieces together for the first time the back story to Mehr Noten als Text and in doing so uncovers a surprisingly heterogeneous network of Freemasons, publishers, and state officials. The findings prompt us to reconsider general questions about the relationship of state and society in the late Enlightenment, the interplay of the public and the arcane spheres and the status of religious heterodoxy at this time.

The generic status of Thuranthos C. H. Wr. is discussed. A key separating the two species is provided. The genus is reported to occur in Natal for the first time. Field studies in Natal have yielded additional information on the habitat, phenology, fruit morphology and pollination biology of  T. macranthum (Bak.) C.H. Wr. Phalaenophily is reported for the second time in the South African Liliaceae. The relationship of T. macranthum with the moth  Diaphone eumela (Cramer)—Noctuidae, Hadeniae, is discussed.

AbstractCheaply available high-quality digital recording equipment, and the ubiquity of computer music tools and the Internet make the creation of electroacoustic music in diverse localities, and its dissemination around the globe, extremely easy. This raises important questions about the relationship of local sound worlds and cultural experience to a potentially global audience. This quandary is examined through the compositions Globalalia (which deals explicitly with speech material from many languages) and Fabulous Paris – a virtual oratorio whcih uses speech in different ways to contrast our relationship to the local and personal with our relationship to the mass experience of the globalised mega-city. The problems in relating to both a local and a global audience are considered in relation to the composer's current project recording speech materials in local communities in the North East of England.

This chapter examines Afghanistan's premodern patterns of political authority and the groups that wielded it. During this period nation-states did not exist and regions found themselves as parts of various empires. During its premodern history, the territory of today's Afghanistan was conquered and ruled by foreign invaders. Located on a fracture zone linking Iran in the west, central Asia in the north, and south Asia in the east, it was the route of choice for armies moving across the Hindu Kush (or south of it) toward the plains of India. For the same reason, empires based in India saw the domination of this region as their first line of defense. This chapter focuses on how (and what kinds of) territory was conquered, how conquerors legitimated their rule, and the relationship of such states with peoples at their margins.

This paper explores the ‘best practice’ interactions between universities and small firms in the UK. The purpose is to identify ways in which a university can build stronger and more effective links with small firms. The relationship between universities and small firms is of growing importance. There are political, economic and educational pressures which influence the behaviour and relationship of higher education toward the business sector, and small firms in particular. The wider context of the changes taking place within higher education are discussed. This is followed by the initial findings from a recently completed research project for the Council for Industry and Higher Education which investigated the foremost components in ‘best practice’ interactions and linkages between small firms and universities in the North East of England. Some preliminary ideas are suggested on how best practice can be further facilitated. These proposals are then interpreted in terms of the operational implications for universities and other strategic organizations involved in building linkages with small firms.

The chromosome complements of four specimens of the anatomically primitive frog Leiopelma hochstetteri are described from cultured cells and squashes. The basic karyotype in all cases consists of 22 chromosomes, 12 of which are acrocentric. Supernumerary chromosomes are either absent or variable in number, but appear to be constant in the somatic cells of any one individual. The limited evidence available suggests that the supernumerary chromosomes do not pair during male meiosis.The karotype of L. archeyi is described for the first time. Only the smallest pair of the total complement of 18 chromosomes is acrocentric. Supernumeraries are absent.The distribution and probable relationships of the species of Leiopelma are discussed. The karyotypes of Leiopelma and the North American ascaphid frog Ascaphus truei are compared, with particular reference to the relationship of the supernumerary chromosomes of Leiopelma and the microchromosomes of Ascaphus.

Abstract. Core samples from the Paleogene of the Bonavista C-99 well on the northeast Newfoundland shelf and cuttings from downdip Blue H-28 contain foraminiferal assemblages which enable reconstruction of paleoenvironments along a downslope transect in Eocene through Late Oligocene-Miocene time. Comparison with coeval assemblages in North Sea wells with respect to structure and grain size of agglutinated taxa between the two areas reveal inter-basin differences.Reconstruction of the paleobathymetry derived from foraminiferal analysis, confirms seismic evidence for shallowing at the Bonavista site beginning in the Early Oligocene. The relationship of the Bonavista assemblages to contour currents is explored with reference to modern regional analogues. Species such as Reticulophragmium amplectens, Haplophragmoides walteri, Eponides umbonatus and Uvigerina ex. gr. miozea-nuttalli persist stratigraphically higher in the deeper Blue site.The paleoslope of this two-well transect is determined as approximately 0.48° during the Middle to Late Eocene and 0.68° during the Late Oligocene-Early Miocene. The bottom water hydrography of the transect can be evaluated by reference to these assemblages and a comparison to flysch-type agglutinated assemblages from a transect in the North Sea. The presence of an Upper Eocene-Middle Miocene hiatus at the Blue site contrasting with apparently continuous Tertiary deposition at Bonavista places a theoretical upper limit of 500–1000 m on the depth of the early Cenozoic western boundary undercurrent.

SynopsisAnalyses of winter and summer vertical migrations of Meganyctiphanes norvegica are given and the differences in behaviour pointed out. A vertical layering of size classes, larger specimens occurring deeper than smaller ones, is shown to exist during the day and night.Four potential methods of feeding were found. The inter-relationships between vertical migration, feeding method used, and type of food eaten are discussed.The relationship of carapace length to total length was found to depend on the state of maturity of M. norvegica.M. norvegica matures at the age of 1 year, transference of the spermatophores taking place in January-February, the eggs being laid in March-April. The larvae take 2–3 months to reach adolescence and little growth in size takes place in the winter when the gonads are maturing. An age of 3 years may be attained but most only survive 1½—2 years.The distribution within the Clyde Sea throughout the year is described. Most of the population were found to move to the North-east Arran Area for egg-laying.A 24-hr. and annual periodicity of luminescence is described and correlated with the period of swarming of this species prior to spermatophore transference.
