Abstract Orobanche coerulescens has a Eurasian distribution. The species is classified as extinct at most of its localities at the western limit of its range. Its populations are very scarce and critically endangered in Central Europe. This work presents the current distribution of O.coerulescens in Poland, based on a critical revision of herbarium and literature data as well as results of original field research, and reviews its distribution in Central Europe (partly in Eastern Europe). Habitats, plant communities, and migration routes of O.coerulescens in Central Europe are discussed. The species was initially known in Poland from now historical localities in Pomerania and the valley of the lower Vistula. In 2000-2011 it was recorded at 9 localities in Podlasie, the Małopolska Upland (Wyżyna Małopolska), and the Łódź Hills (Wzniesienia Łódzkie). Its abundance at the localities ranged from a few to over 1000 shoots. These are the largest populations of O.coerulescens at its western and north-western range limits.

Based on comprehensive environmental monitoring, geobotanical, zoogeographical, landscape-ecological, hydro-ecological, forest-typological, agroecological principles and approaches and own field research it is proposed to create a national nature park (NNP) «Central Podillya» within Vinnytsia region. A promising NNP is planned to be created on the territory of Vinnytsia and Khmilnytsky administrative districts of Vinnytsia region as a habitat and migration routes of bison (Bison bonasus) and preservation of unique biotic and landscape diversity. The projected area of NPP «Central Podillya» is 53 820 hectares. The need to create a park due to the presence of natural (forest, wetland, peat-swamp, floodplain, meadow, forest-steppe, meadow-steppe, steppe, weed-field) complexes with associations of plant groups, where more than 40 species of plants and lives more than 50 species of animals listed in the RBU, as well as the presence of a significant number of objects that have historical, cultural, recreational, health (medical) value. The general ecological and geographical characteristics of the park from the standpoint of physical-geographical and geobotanical zoning are given. There are 34 objects of the nature reserve fund (NRF), which will be a part of the perspective park. Functional zoning of the territory of the projected NNP «Central Podillya» was carried out taking into account representative and rare ecosystems, where its 4 zones (protected, regulated recreation, stationary recreation, economic) were allocated. The structural elements of the ecological network of the perspective park are singled out. The necessity of protection, preservation and reproduction of biotic and landscape diversity and historical and cultural heritage of the studied territory through the greening of economic activity, education and culture of the local population is substantiated. It was found that the creation of NPP «Central Podillya» through the Presidential Decree and the optimization of protected areas, which account for 2.27% of the total area of Vinnytsia region, the implementation of regional ecological and Emerald networks is an extremely important, important and absolutely necessary for effective adjustment of the strategy of balanced development of territorial communities. Creation of NPP «Central Podillya» will increase the percentage of protected areas to 4.5% of the total area of Vinnytsia region. According to this indicator Vinnytsia region is in one of the last places in Ukraine. According to the Institute of World Resources (Washington), for the effective functioning of the territory, the area of its reserves should be at least 10–12%. Preparation of scientific substantiation and project of creation of NPP «Central Podillya» within Vinnytsia region is a pilot project that requires official detailing, delimitation, land management, coordination with land users on which the park will be located, creation of park directorate, introduction of technologies aimed at preservation and restoration of biogeocenotic cover, reproduction of broken types of connections, preservation of settlements, optimization of land use, balanced development of territorial communities that will be a part of the NNP.

Abstract The paper presents the current distribution of Orobanche alba subsp. major and subsp. alba in Poland, based on a critical revision of herbarium and literature data as well as results of my field studies. Most of their localities are in southeastern Poland: in the Małopolska Upland, Lublin Upland, Roztocze Hills, Polesie, Przemyśl Foothills (Pogórze Przemyskie), and Western Bieszczady Mts. These are the northernmost sites known for the species in Central Europe, so the new data extend its distribution range. Maps of distribution of both the subspecies in Poland and of subsp. major in Central Europe are included. Additionally, their seed micromorphology was compared using scanning electron microscopy (SEM). The taxonomy, biology, and ecology of both the subspecies of O. alba are also discussed.

This article scrutinizes the trajectories of African men whose cross-border movements intersect two types of mobility routes: mining and migration routes. Drawing on field research in Mali and Guinea, as well as phone interviews with male miners/migrants in North Africa and Europe, this article provides a case to empirically question some of the premises in the approach to migration decision-making by giving a voice to African men moving across borders who do not necessarily identify as (prospective) ‘migrants.’ Building upon International Organization for Migration data and secondary sources, this article starts by sketching where migration and mining routes overlap. It then examines, in detail, the mobility trajectories of men who were sometimes considered migrants and other times miners in order to identify how these different routes relate to one another. While overseas migration is certainly not a common project for itinerant miners, the gold mines constitute a transnational space that fosters the expansion of movements across the continent, including outside the field of mining. Rather than encouraging overseas migration, gold mines appear to be more of a safety net, not only for seasonal farmers or young people in search of money and adventure, but also, increasingly, for people who are confronted with Europe’s intra-African deportation regime.

Abstract The paper presents the current distribution of Orobanche purpurea s. str. (excl. O. bohemica) in Poland, based on a critical revision of herbarium and literature data as well as results of my field research. Most of the records date back to the 19th or early 20th century and are now historical. Most of them lack also herbarium documentation. Since the 1950s the species has been found in 10 new localities, only partly documented by herbarium specimens. Currently it is present in only 4 localities, in valleys of the Lower Vistula and the Lower Oder (Odra) rivers and in the Silesian-Kraków Upland (Wyżyna alπsko-Krakowska). These are some of the northernmost sites known for the species, and the new data extend its continuous distribution range. A map of its distribution in Poland is included. The taxonomy, biology, and ecology of O.purpurea are also discussed.

The results of a sintaxonomical study of plant communities of the Yamozero lake (the North-East of the European part of Russia) are presented. The diversity of the aquatic and helophytic vegetation of the Yamozero lake consists of 16 associations and 2 communities of 6 unions, 4 orders and 2 classes of the floristic classification: Potamogetonetea (7 associations, 2 communities), Phragmito-Magnocaricetea (9 associations). Many of described associations are widely distributed in the Central and the Eastern Europe. Some associations have the boundaries of their ranges. Some communities include 2 rare species of regional level: Isoetes setacea and Sagittaria natans.

Abstract Eastern (Vireo gilvus gilvus) and western (V. g. swainsoni) forms of the Warbling Vireo have essentially allopatric breeding ranges across north-central North America, but come into contact in central Alberta, Canada. In 1986, Jon Barlow presented preliminary morphological and song evidence suggesting that the Warbling Vireo complex might comprise more than one valid species. However, to date, Barlow’s suggestion is supported by only limited DNA evidence, demonstration of molt and migration differences between the taxa, and anecdotal accounts of differences in song, morphology, plumage, and ecology. We analyzed variation in both mitochondrial and nuclear DNA in birds from Alberta and surrounding areas to determine the levels of genetic differentiation and hybridization occurring in the contact zone, and whether the two taxa warrant recognition as separate biological species. Our analyses reveal that Warbling Vireos in Alberta and the surrounding areas are separated into two well-defined, genetically differentiated, and monophyletic clades corresponding to previously recognized taxonomic groups. The two taxa come into contact in a narrow (~85 km) zone in Barrhead County, northwest of Edmonton, Alberta. They show evidence of limited hybridization. The distinct genetic differences are maintained in the contact zone, where individuals of the two taxa may occupy neighboring territories. Differences in spring arrival dates, molt schedules, and migration routes indicate that a migratory divide may play an important role in reproductive isolation. We suggest that the two taxa are distinct cryptic species: an eastern form, Vireo gilvus, and a western form, Vireo swainsoni.

By abolishing feudalism, the Hungarian Revolution of 1848 helped to create the economic preconditions and the legal-political framework necessary for capitalistic development. This made it possible for Hungary to adapt her economy to the market possibilities offered by the Industrial Revolution in western and central Europe and to share in the agrarian boom of the period between 1850 and 1873. The previously existing division of labor between western and eastern Europe and between the western and eastern parts of the Habsburg monarchy continued on a scale larger than before, with the significant difference, however, that this practice now speeded up rather than retarded the development of preconditions for capitalism. During the first half of the nineteenth century the preconditions for capitalism had come into existence in the Cisleithanian provinces at considerable expense to the Hungarian economy.

Abstract Early pottery on the territory from the Eastern Caspian Sea and Aral Sea to Denmark reveals a certain typological similarity. It is represented by egg-shaped vessels with an S-shaped profile of the upper part and a pointed bottom. The vessels are not ornamented or decorated with incised lines, organized often in a net. This type of pottery was spread within hunter-gatherer ancient groups. The forest-steppe Volga region is one of the earliest centers of pottery production in Eastern Europe. The first pottery is recorded here in the last quarter of the seventh millennium BC. Its appearance is associated with the bearers of the Elshanskaya cultural tradition. The most likely source of its formation is the territory of Central Asia. Later, due to aridization, these ceramic traditions distributed further westward to the forest-steppe Don region. During the first half of the sixth millennium BC, groups associated with the bearers of the Elshanskaya cultural tradition moved westward. Significant similarities with the ceramic complexes of the Elshanskaya culture are found in materials from a number of early pottery cultures of Central Europe and the Baltic (Narva, Neman, and Ertebølle).

This book describes the choices open to farming families in the Sahelian village of Kala, in central Mali. Life in this drought-prone region is harsh and full of risk to health, crops, and livestock, yet there are also opportunities open to the hard-working, audacious and lucky, bringing considerable returns if the timing is right. Three inter-related themes underlie the analysis of production and investment decisions faced by households; the role of risk, the long timeframe within which decisions are made, and the close links between economic performance and household size and organisation. Climatic variability and demographic uncertainty lie at the heart of domestic structures; the extreme vulnerability faced by single individuals means people cluster in large kin-based groups, pooling risks and providing protection. The very limited development of labour markets means that households rely almost entirely on their own members for their workforce, and generating the capital needed for investing in ploughs, wells, carts and livestock must stem from a good year’s grain surplus and migration earnings. Based on field-research over the period 1980-82, this study illustrates a successful response to making ends meet in a land abundant region, despite high risks of drought. A follow-up study of this village was published in 2020: Land, Investment, and Migration. Thirty-five years of village life in Mali (OUP).
