During the 20th century many insect species have expanded into Finland and established themselves as part of the fauna. Some species of Coleoptera seem to have been carried here originally by man, but nowadays live outdoors. Many other species seem to have reached Finland on their own, and colonized a minor or major part of the country. Most colonists have come from the south, only a few from the east or north-east. This article lists various kinds of newcomers to Finland.

Bombus pomorum (Panzer, 1805) is known from Europe, Anatolia, the Caucasus, and to the Urals in Russia.  Two specimens have been collected in the south of western Siberia for the first time.  It is possible that the species is indigenous to Siberia but was not discovered until regular observations were made.  There is also a possibility that this observation results from an expansion of the range of B. pomorum.  We consider the evidence that our study coincided with a range expansion of the bumblebee species B. pomorum and B. sylvarum (Linnaeus,1761) near the end of 20th century.  The distribution and abundance of B. pomorum in Russia and conservation efforts are also discussed.

NOTE: This article was published in a former series of GEUS Bulletin. Please use the original series name when citing this article, for example: Kalsbeek, F., & Skjernaa, L. (1999). The Archaean Atâ intrusive complex (Atâ tonalite), north-east Disko Bugt, West Greenland. Geology of Greenland Survey Bulletin, 181, 103-112. https://doi.org/10.34194/ggub.v181.5118 _______________ The 2800 Ma Atâ intrusive complex (elsewhere referred to as ‘Atâ granite’ or ‘Atâ tonalite’), which occupies an area of c. 400 km2 in the area north-east of Disko Bugt, was emplaced into grey migmatitic gneisses and supracrustal rocks. At its southern border the Atâ complex is cut by younger granites. The complex is divided by a belt of supracrustal rocks into a western, mainly tonalitic part, and an eastern part consisting mainly of granodiorite and trondhjemite. The ‘eastern complex’ is a classical pluton. It is little deformed in its central part, displaying well-preserved igneous layering and local orbicular textures. Near its intrusive contact with the overlying supracrustal rocks the rocks become foliated, with foliation parallel to the contact. The Atâ intrusive complex has escaped much of the later Archaean and early Proterozoic deformation and metamorphism that characterises the gneisses to the north and to the south; it belongs to the best-preserved Archaean tonalite-trondhjemite-granodiorite intrusions in Greenland.

THE Carlingford-Barnave district falls within the boundaries of Sheet 71 of the Ordnance Survey of Ireland, and forms part of a broad promontory lying between Carlingford Lough on the north-east and Dundalk Bay on the south-west. The greater part of this promontory is made up of an igneous complex of Tertiary age which has invaded the Silurian slates and quartzites and the Carboniferous Limestone Series. This complex has not yet been investigated in detail, but for the purposes of the present paper certain references to it are necessary, and these are made below. The prevalence of hybrid-relations and contamination-effects between the basic and acid igneous rocks of the region is a very marked feature, and because of this it has been difficult at times to decide which types have been responsible for the various stages of the metamorphism.

A taxonomic revision of the Nystiellidae from Brazil, including samples from the Rio Grande Rise, South Atlantic, was performed based on shell morphology. Five genera and 17 species were recognized. For the richest genus,Eccliseogyra, the three species previously recorded from Brazil were revised:E. brasiliensisandE. maracatu, previously known only from their respective type series, were re-examined. Newly available material ofE. maracatuexpanded the known geographic range of this species to off south-east Brazil.Eccliseogyra nitidais now recorded from north-eastern to south-eastern Brazil, as well as from the Rio Grande Rise. Three species ofEccliseogyraare newly recorded from the South Atlantic:E. monnioti, previously known from the north-eastern Atlantic, occurs off eastern Brazil and on the Rio Grande Rise; its protoconch is described for the first time, confirming its family allocation.Eccliseogyra pyrrhiasoccurs off eastern Brazil and on the Rio Grande Rise, andE. folinioff eastern Brazil. The genusIphitusis newly recorded from the South Atlantic.Iphitus robertsiwas found off northern Brazil, although the shells show some differences from the type material, with less-pronounced spiral keels. Additional new finds showed thatIphitus cancellatusranges from eastern Brazil to the Rio Grande Rise, and Iphitusnotiossp. nov. is restricted to the Rio Grande Rise.Narrimania, previously recorded from Brazil based on dubious records, is confirmed, including the only two living species described for the genus:N. azelotes, previously only known from the type locality in Florida, andN. concinna, previously known from the Mediterranean. A third species,Narrimania raquelaesp. nov. is described from eastern Brazil, diagnosed by its numerous and thinner cancellate sculpture. To the three species ofOpaliopsispreviously known from Brazil, a fourth species,O. arnaldoisp. nov., is added from eastern Brazil, and diagnosed by its very thin spiral sculpture, absence of a varix, and thinner microscopic parallel axial striae.Papuliscala nordestina, originally described from north-east Brazil, is recorded off eastern Brazil and synonymized withP. elongata, a species previously known only from the North Atlantic.

The new material on which this paper is based has lately been received through Mr. D. Ferguson, who recently investigated the geology of the island, and collected the rocks described in an earlier paper. It consists of twenty-seven rock specimens from the south-eastern end of the island, between Cape Disappointment and Cooper Island, and nine specimens from Gold Harbour on the north-east coast between Cooper Island and Royal Bay. All these were collected by the staff of the South Georgia Co., Ltd., under the instructions of Mr. Th. E. Salvesen, managing director, of Leith.

The article considers the activities of Ivan Kraft, the governor of Yakutsk Oblast, on the incorporation of North-East Siberia into the single economic, administrative and sociocultural space of the Russian Empire. The aim of the study is to analyze Kraft's contribution to the construction and arrangement of the Amur-Yakutsk Highway at the beginning of the 20th century. To reach this aim, the authors broadly use archival sources that have not been previously published and introduced into academic discourse. The topic has theoretical and applied relevance. It has not been sufficiently studied in the historiography of North-East Siberia and is the subject of scholarly and political discussions. The key method in the study is an interdisciplinary approach to the research problem, which is at the intersection of history and economics. The authors used content analysis for a quantitative and qualitative study of these sources based on the principle of historicism and consistency. The authors determined that, in connection with the design of the Amur Railway, the Amur-Yakutsk Highway received the status of a strategic infrastructure object in the macroregion. The authors note that Kraft was the initiator of the construction of the route from Yakutsk to the Amur. The governor conducted a number of scientific and engineering surveys of the most convenient route and made applications for financing the construction of the highway. Kraft made a strategic decision to attract private companies with large capital for the construction. The Upper Amur Gold Mining Company and the Heirs of A. I. Gromova company helped build highway sections with a total length of more than 500 km, equip stations, establish telegraph communications, and construct river crossings. At the beginning of the 20th century, in the framework of modernization measures, Kraft considered Yakutsk Oblast as a mining region. This became the basis for raising the question of Yakutia's access to the Trans-Siberian Railway. The close cooperation of the government, in the person of Kraft, with large enterprises of the region was the basis for the project of constructing a railway line to Yakutsk. In conclusion, the authors note that the processes of incorporation of the Asian borderlands of Russia into the economic, administrative and sociocultural space of the state that Governor of Yakutsk Oblast Ivan Kraft began at the beginning of the 20th century were reflected in the modern policy of the Russian Federation. The Amur-Yakutsk Mainline was put into operation in 2015. At present, the problem of building a bridge across the Lena in the Yakutsk area is still relevant. In 2019, President of the Russian Federation Vladimir Putin signed orders to begin the construction of the bridge. This will create an international transit corridor between Europe and the Asia-Pacific region.

Purpose: Determination of the peculiarities of the behavior and the flow of childbirth in females (wrenches) of the northern home deer of the Even Breed of the Republic of Sakha (Yakutia), depending on the natural climatic zone of breeding.Material and research methods. Research of the reservation of the hotel's reservoir of the northern home deer was held from April to June in the reindeer herds of the mountain-taiga (FSUE «Yuchjuyuskoye») and the Tundrov zones (SHPZK «Taba-Yana») of the Republic of Sakha (Yakutia) in the conditions of nomadic home reindeer herding since 2013 2018 In the study, the method of observation is used with the registration of motor activity of animals and the activities of individual bodies in a certain living environment.Results. To fix some patterns and species features of the generic process, 8 main elementary behavioral reactions spent venizables of northern domestic deer per day before childbirth: walking, feeding feed, chewing, leisure standing, rest lying, sleep, urination (how many times / total time), defecation (how many times / total time). Also marked 4 behavioral reactions on the hotel day: the exploitation time of the fetus, the licking of the calf, the time of the calf on his feet after delivery, the first reception of the mosper calf after birth. For each parameter, data reflected in tabular format is obtained.Conclusion. It has been established that the degree of adaptation of the northern domestic deer to the harsh conditions of existence in various natural-climatic zones of the Republic of Sakha (Yakutia) is very high, which is manifested in a minor difference in the duration of the generic process and behavioral reactions at the vainer of the mountain and tundra and tundra dilution zones.

The Cyclopean Terrace Building lies to the north-west of the Lion Gate on the northern end of the Panagia Ridge and faces almost due west across the valley of the Kephissos and modern main road from Corinth to Argos. It lies just below the 200 m. contour line, and one terrace below the houses excavated in 1950–51 by Dr. Papadimitriou and Mr. Petsas to the east at the same end of the ridge. The area contains a complex of buildings, both successive and contemporary, and in view of the discovery of structures both to the south-west and, by the Greek Archaeological Service, to the north-east it is likely that this whole slope was covered by a portion of the outer town of Mycenae. This report will deal only with the structure to which the name Cyclopean Terrace Building was originally given, the so-called ‘North Megaron’, supported by the heavy main terrace wall.The excavation of this structure was begun in 1923. The main terrace wall was cleared and two L.H. IIIC burials discovered in the top of the fill in the south room. In 1950 it was decided to attempt to clear this building entirely in an endeavour to find out its date and purpose. The clearing was not, however, substantially completed until the close of the 1953 excavation season, and this report presents the available evidence for the date as determined by the pottery found beneath the building; the purpose is still a matter for study, though various tentative conclusions can be put forward.
