Thirty species of Odonata are known to occur in the north-west of Western Australia, between the De Grey and Gascoyne Rivers. Eight of these species, from the families Coenagrionidae, Protoneuridae, Gomphidae, Corduliidae, and Libellulidae, belong to taxa here described as new. All the north-western dragonflies are either of tropical affinity, or widespread species. The species confined to permanent waters, i.e. to conditions of relatively mild temperatures and high oxygen tensions, are commonly more distinct from closest relatives in the Kimberley region or northern Queensland, than Kimberley and Queensland species are from each other. Such disjunct species show limited dispersal as adults.

The species composition and broad trophic structure of the mangrove creek and open shore fish communities of the Dampier region in tropical north-western Australia are described. The habitats are characterized by a lack of freshwater influence, low turbidity and a tidal range in excess of 4 m. Both mangroves and open shores have a diversity of species typical of Indo-west Pacific coastal waters but the physical conditions have modified the community structure both to exclude many families that prefer areas of higher turbidity and reduced salinity, and to include others that usually occur only in clear waters. The fish faunas of the mangroves (113 species) and open shores (106 species) are compared: 54 species were common to both. The deeper waters were dominated by piscivores, which penetrated throughout the mangroves at high tide. Iliophagous species were abundant, particularly in the mangroves where the organic content of the substratum (7.8-8.2%) was not reduced markedly compared with other areas of the Indo-Pacific, despite the lack of freshwater inflow. The clear and deep water in the mangroves at high tide favour predation on juveniles by piscivorous fishes and reduce the effectiveness of such areas as nurseries. There is virtually no overlap of the fauna with that of the deeper waters (>20 m) of the North West Shelf, and the inshore region is not a significant nursery ground for any of the commercially important deeper water species.

SummaryPalaeocurrent directions from cross-beds in the Proterozoic Kimberley Basin sediments, north-western Australia indicate sediment transport predominantly from the north-east in the lower part of the succession, and from the north-west in the middle and upper parts. Most of the sediment was probably derived from the north and only a little from the adjacent exposed areas of older Pre-Cambrian rocks to the south. The suggested northerly source of the sediment is consistent with a probable former position of Western Australia close to Peninsular India and to Burma.

Commercial catch rates for the North West Shelf trap fishery, at up to 10 kg trap-1 h-1, are considerably greater than those reported for similar trap fisheries elsewhere. Two fish-trapping experiments were conducted off Lowendal Island (north-western Australia) to study the catch rates of four trap types (O-, S- and Z-shaped and rotational) and two bait types (pilchard, Sardinops neopilchardus, and emperor, Lethrinus choerorynchus) over various soak times (ranging from 1 to 24 h). Total catches varied significantly with soak time. Catches increased rapidly for the first 3 h, levelled off, and then decreased steadily to 16 h; there was a slight increase at 24 h. The species composition of the catch did not vary significantly with soak time. There was no significant difference in catch rates between trap types. The traps did not appear to cause fish to die by being confined in the traps for extended periods. A fairly large amount of suitable bait (about 4 kg) was necessary for effective trapping of fish. The catch rates of the pilchard bait were significantly higher than those of the emperor bait. Over extended soak times (more than 3 h), pilchard bait was lost at a rate of about 6% h-1. whereas there was no detectable loss of emperor bait.

This chapter studies cultural invention in light of the North-Western European cultural movement called Enlightenment. Enlightenment refers, in the first place, to a description by European intellectuals of what they took to be an advanced present state of moral and natural knowledge by comparison to that of the ancients. With related self-confidence, in the heyday of their empires, some described their culture as possessed of a dynamic modernity to be distinguished from the ‘oriental' lethargy and backwardness existing elsewhere. Yet Enlightenment also originated as European self-criticism. One context for that was the comparative perspective acquired by discovery of non-European cultures. In this and in other ways the origin of Enlightenment, including its ‘conviction that progress had become unstoppable', lies in the period when Renaissance and Reformation combined with printing and natural philosophy to establish the culture of the European North-West.

February 18, 2021, a flank eruption started on the north-western slope of the Klyuchevskoy Volcano (Kamchatka, Russia). Cinder cone was formed at the altitude of 2 850 m above sea level, from which a lava flow was spreading north-west. Having moved 1.2 km downslope, the lava flow entered the Ehrmann Glacier, which resulted in the formation of huge mud-stone flows. The latter made their way further north-east along the Kruten’kaya River bed and reached the length of about 30 km. The eruption brought onto the surface high-aluminous basaltic andesites typical of the Klyuchevskoy Volcano. By March 21, the flank eruption ended. It has been named after G.S. Gorshkov, associate member of USSR Academy of Science, famous Russian volcanologist.

Introduction. History of the North-West area of Novgorod land at the end of the XV century attracted the attention of researchers mainly in the socio-economic aspect. This is due to the fact that Novgorod scribal books are dated by the end of the XV century. From the standpoint of socio-economic history their value is not in doubt, but from an ethno-historical point their onomastic content is underestimated. Materials and methods. The main source of research was the scribe book of the Vodskaya Pyatina 1499/1500. The descriptive method of research is to identify and record the Baltic-Finnish oikonyms (names of rural settlements) and anthroponyms mentioned in the scribe books. Baltic-Finnish anthroponyms are identified on the basis of an analysis of formal indicators of borrowing the anthroponyms. Results and Discussion. There are several areas where the Baltic-Finnish oikonymy and anthroponymy were concentrated, namely Korboselsky graveyard in the northern Prinevye, Lopsky and Terebuzhsky graveyards in the southern Ladoga, as well as Dudorovsky and Izhora graveyards south of the Neva. Archaeological sources record a significant presence of the Izhora antiquities. The presence of Karelians is noted in the northern Prievye and southern Ladoga. Slavic onomastic materials are recorded throughout Orekhovsky and Ladoga counties, but to mostly in the cities of Oreshka, Ladoga and their nearest areas. Conclusion. By the end of the XV century the north-western graveyards of Novgorod land were inhabited by representatives of various ethnic groups: Slavs, Vodians, Izhora and Karelians, as evidenced by the data of anthroponyms and toponyms of the scribe’s books and confirmed by archaeological sources.

The Baltic elements in the grammar of traditional local dialects of north-western BelarusThe article analyzes a number of grammatical features typical for the North-West dialect zone of the Belarusian language. These peculiarities are interpreted as a possible result of Slavic-Baltic contacts in the region. Some phenomena can be explained as a Baltic (mainly (great)Lithuanian) substratum in North-West Belarusian dialects.The factor of areal neighborhood has to be taken into consideration too. Such phenomenon as language support has effect just in connection with the last one. A lot of the appropriate lingual facts are in restricted and inconsistent use. However, it is possible to be said about more or less significant (now or/and before) tendencies of regional lingual development. These tendencies has not got the status of a structural (= constitutional) lingual regularity. As a rule the wide and compact areas are characterized of some lingual facts (= lexemes), which illustrate the given transformations in the system of Belarusian dialects. Baltic influence upon the North-West Belarusian dialects grammar is detected on as the formal level so the structural one. And it is not noticeable at all times. The definite changes in the sphere of morphology and syntax can provoke different modifications in the other parts of a language system (word building, semantics). The results of this process are the evidences of ethnic and language assimilation of native Balts by Slavs in the region. That comes in support of forming the singular North-West Belarusian regiolect (= the regionally marked variety of a dialect language). Балтийские грамматические элементы в говорах северо-западной БеларусиВ статье анализируется ряд грамматических черт, характерных для говоров северо-западной диалектной зоны беларусского языка. Эти особенности квалифицируются автором как весьма вероятное следствие славяно-балтского языкового взаимодействия в соответствующем регионе. Отдельные явления есть основания рассматривать в качестве возможного проявления балтского (главным образом (пра-) литовского) субстрата в северо-западных беларусских говорах. Фактор ареальной смежности здесь также должен быть принят во внимание. В связи с последним следует упомянуть и действие феномена языковой поддержки. Многие соответствующие языковые факты имеют существенные ограничения в употреблении, в говорах выступают не всегда последовательно и регулярно. В некоторых случаях, однако, можно говорить о действии более или менее выраженных (в настоящем и/или прошлом) тенденций регионального языкового развития, которые пока не приобрели статус структурно значимой (= конститутивной) языковой закономерности. Широкие и компактные ареалы образуют, как правило, лишь отдельные языковые факты (= лексемы), иллюстрирующие данные трансформации в системе традиционных беларусских говоров. Балтское влияние на грамматический строй беларусских говоров северо-западной диалектной зоны выявляется как в плане формального выражения, так и на внутриструктурном уровне. Оно не всегда может быть заметно на первый взгляд. Определенные сдвиги в сфере морфологии и синтаксиса могут повлечь за собой изменения в других областях языковой системы (словообразовании, семантике). Результаты этого процесса являются ярким свидетельством того, что на отмеченной территории действительно имела место этноязыковая ассимиляция неславянского (= балтского) населения и происхо- дило формирование своеобразного северо-западного беларусского региолекта (= регионально обусловленной разновидности диалектной речи).

This paper deals with the preliminary results of the typological and analytical study of a collection of copper-based objects found at the site of Castelo Velho (Freixo de Numão). This collection is associated to different contexts from the 3rd millennium BC (Chalcolithic). The analyses, performed by non-destructive X-ray fluorescence (XRF), show that the metals were produced with almost pure copper and arsenical copper (> 2% As). Impurities, such as As (<2%), Fe, Bi, Ag, Sn, Sb and Ni, were also identified, likely due to their presence in the ores used for the production of the objects. The data suggest that the metals from Castelo Velho may be framed within the metallurgical production already known for the Chalcolithic of the North-Western Iberian Peninsula.

The “North-Western Prakrit” as Konow has called it is represented by the following documents.(1) The two versions of Aśoka's edicts preserved at Mansehra’ and Shahbazgarhi. At this stage many of the characteristic features of the language have not yet developed, e.g. śr > ṣ, śv > śp.(2) The later Kharoṣṭhi inscriptions, mostly short, collected by Konow in the second volume of the Corp. Inscr. Ind.(3) The Kharoṣṭhi manuscript of the Dhammapada discovered near Khotan (Manuscript Dutreuil du Rhins).(4) The Kharoṣṭhi documents from Niya, representing the administrative language of the Shan-Shan kingdom in the third century A.D. In the Journ. As., 1912, pp. 337 ff., J. Bloch examined the dialectical peculiarities of the Manuscript Dutreuil du Rhins and showed that they appeared in modern times in the languages of the North-West.

This chapter explains the coverage of this book, which is about the comparison of rulers, warriors, traders, and clerics on the central Sahel and the North Sea region. It argues that there was more similarity between north-western Europe and the central Sahel in the few centuries either side of AD 1001 than has hitherto been recognised, and maintains that the nature of the sources has obscured these formative times and left them in the shadow of organised structures. It discusses the interconnectedness of central Sahel and north-west Europe through contacts and shared pre-industrial nature.
