Species in the Pseudomys australis complex were historically widely distributed in a variety of habitats over southern Australia. By 1990 the group had apparently declined to a single species in the centre of its former range in the north-western Lake Eyre Basin, in gibber plain areas. In the past, the species has been collected only after exceptional annual rainfall. This study sought to define the current distribution of P. australis and to determine its preferred habitats during the usual prolonged dry periods. Allozyme electrophoresis on blood and tissue samples were used to investigate the genetic distinctiveness of geographically separated populations. The known distribution has been extended along a belt of gibber habitats running from north-west of Lake Eyre on the Northern Territory border to south of Lake Eyre South, and a discrete population inhabiting gibber tableland west of Lake Torrens. Pseudomys australis was extant in low-lying patches of deep cracking clay associated with minor drainage features and small depressions of cracking clay ‘gilgai’ common on some gibber plains. The former type sustained significantly denser populations, which we suggest represent ‘source’ habitats or ‘refugia’ during droughts. Many of the 16 localities at which the species was recorded are geographically separated; however, electrophoretic analyses showed high levels of allozyme heterozygosity and no evidence of speciation.

AbstractThe city of Essaouira is located along the north-west coast of Morocco, where groundwater is the main source of drinking, domestic and agricultural water. In recent decades, the salinity of groundwater has increased, which is why geochemical techniques and environmental isotopes have been used to determine the main sources of groundwater recharge and salinization. The hydrochemical study shows that for the years 1995, 2007, 2016 and 2019, the chemical composition of groundwater in the study area consists of HCO3–Ca–Mg, Cl–Ca–Mg, SO4–Ca and Cl–Na chemical facies. The results show that from 1995 to 2019, electrical conductivity increased and that could be explained by a decrease in annual rainfall in relation to climate change and water–rock interaction processes. Geochemical and environmental isotope data show that the main geochemical mechanisms controlling the hydrochemical evolution of groundwater in the Cenomanian–Turonian aquifer are the water–rock interaction and the cation exchange process. The diagram of δ2H = 8 * δ18O + 10 shows that the isotopic contents are close or above to the Global Meteoric Water Line, which suggests that the aquifer is recharged by precipitation of Atlantic origin. In conclusion, groundwater withdrawal should be well controlled to prevent groundwater salinization and further intrusion of seawater due to the lack of annual groundwater recharge in the Essaouira region.

Baited lander represents a low impact technique, an alternative to the traditional trawl sampling for collecting data on fish diversity and abundance, especially for threatened species such as Chondrichthyes living in sensitive habitats. In this study, distribution and abundance of cartilaginous fish were compared between two geographic areas, the southern Adriatic Sea and the north-western Ionian Sea, with two low impact sampling gears, an experimental bottom longline and a baited lander. Species diversity was evaluated by applying ecological indices and difference in mean abundances were tested using multivariate analysis. A total of 13 species of cartilaginous fish were collected. Significant differences in the assemblage recorded in the same area using different sampling tools were detected and no significant differences were detected among different areas explored with the same method. Using longline, the most abundant species collected in both areas was Galeus melastomus, while using lander, the most observed species were Dalatias licha in the southern Adriatic Sea and Hexanchus griseus in the north-western Ionian Sea. According to IUCN classification, of the 13 species collected, 2 are near threatened and 5 are threatened. A better governance of sensitive habitats coinciding with the essential fish habitat for these species would ensure them a better conservation status.

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.

This article critically discusses solidarity actions in support of Pussy Riot within the global North/West, arguing that most solidarity projects within popular culture as well as within the queer-feminist counterculture are based on a lopsided interpretation of Pussy Riot as Russian version of Riot Grrrl feminists. This onedimensional interpretation of the performance art group as Riot Grrrl-identities further leads to labelling their performance at the Christ the Saviour Cathedral as anti-religious. Within this framework the group’s negotiation of Orthodox religion within their song lyrics, performances as well as statements is ignored, supporting the binary construction of The North/West as progressive – tolerant and secular – and Russia as backward – dogmatic and fundamentalist religious. We attempt to complicate the view on Pussy Riot’s performances and reread them within the Russian context, highlighting several political statements that got lost in North/Western translations. The focus of the analysis concentrates on the ‘Punk Prayerr’, its mimicry of religious language and references to the leadership of the Russian Orthodox Church as well as the local public critical discourses.
