The study of the current state and habitats of rare and threatened species of plants is a relevant task of ecological research. The paper presents the results of the study of systematic position, habitats and modern state of populations of a rare species included in the Red DataBook of Ukraine Carlina cirsioides Klokov (=C. acaulis L.). Carlina cirsioides is well-known to European phytosozologists as an endemic and relic species of the Flora of Ukraine. At the same time, the species independence of this taxon is not recognized by the authors of monographs on the Carlina genus and by the authors of “Flora Europaea”. Comparative morphological, chorological and ecological-coenotic analyses do not give sufficient reasons to consider C. cirsioides described by Klokov as a separate species, endemic and relic species of the Flora of Ukraine. According to the morphological traits, the specimens from the lowland part of Ukraine belong to the C. acaulis caulescens subspecies, which is distributed mostly in the lowlaand regions of Europe. Ecological-coenotic conditions of habitats of C. acaulis in the plains of Ukraine are different from those in the mountain regions and are close to the plains habitats of this species in Central Europe. Steppe communities of class Festuco-Brometea, of which C. acaulis is component in the plains part of Ukraine, are close to xerothermic herbaceous communities of Central Europe; forest communities of Erico-Pinetea with C. cirsioides in Ukrainian Polissia and the North-East Poland are very сlose by floristic composition. The removal of separate species status of the plains populations of C. acaulis near the eastern border of the range does not at all downplay its sozological significance. Taking into account the low number of C. acaulis in the Volhynian-Podolian Upland and in the Polesian Lowland, all localities of this species in the lowland part of the range in Ukraine must be taken under protection in situ.

Data Book

The systematic position and modern state of populations of the rare species of Ukrainian flora Carlina cirsioides Klokov (Asteraceae) are considered. Since this species is included into the Red Data Book of Ukraine (2009) and the European List of Globally Threatened Animals and Plants (1991), it is well-known for European botanists as an endemic of the Ukrainian flora. However, neither the authors of Flora Europaea (1976), nor monographers of the genus Carlina recognize Carlina cirsioides as a separate species. Comparative morphological, chorological, and coenotic analyzes does not allow Carlina cirsioides to be considered as a separate species, endemic and relic of the Ukrainian flora. According to morphological features, specimens from the plains of Ukraine are referred to the subspecies Carlina acaulis caulescens, which is distributed mainly in plain regions of Europe. Ecological and coenotic conditions of habitats of Carlina acaulis in the lowland part of Ukraine are different from its habitats in the Carpathians and Alps and are close to xerotherme grass communities with Carlina acaulis of plains of Central Europe. Steppe communities of Festuco-Brometea class with Carlina acaulis in the Volhynian-Podolian Upland are similar to xerotherme communities with Carlina acaulis of Central Europe. Erico-Pinetea class communities are common habitats for Carlina acaulis in the Ukrainian Polissia and north-eastern Poland. Lowering the species status of Carlina cirsioides from separate species to subspecies Carlina acaulis caulescens does not diminish its phytosozological value. Due to the low number of Carlina acaulis populations in the Volhynian-Podolian Upland and Polissia, all localities of this species in the lowland part of Ukraine need to be provided by protection.

The early Neolithic rondel is a large curvilinear ditched and palisaded enclosure found in increasing numbers in Central Europe. It has close links with the tells of the Danube region, themselves highly suggestive instruments of the earliest Neolithic. Here the authors extend the distribution of rondels further to the north-east, with the discovery and verification of the first example in Poland. As they point out, it is aerial photography that made this advance possible and we can expect many more discoveries, given appropriate investment in the art.

The ellobiopsid genus Thalassomyces is of uncertain systematic position, having been allied at various times with the fungi, algae and protozoa, and little is known of its biology. Discovery of a flagellate stage suggested to Gait & Whisler (1970) that the genus is a member of the achlorophyllous Dinophyceae (Dinoflagellata). T. fagei (Boschma, 1949) appears to be restricted to euphausiids (of which there are 85 valid species in 11 genera-see Mauchline & Fisher, 1969). According to Vader (1973), T. fagei has been recorded in different areas from various euphausiid species, i.e. in 11 (perhaps 12) species of Euphausia, two of Nycliphanes, three of Thysanoessa, and in Nematoscelis difficilis and M. novegica. Other Thalassomyces species are found in mysid, decapod and amphidpod crustaceans (Vader, 1973).

Culture Sequence

In 1931 I described two newly-discovered stone age industries of post-glacial age situated in north-east Ireland which had been made by myself and worked in conjunction with my friend C. Blake Whelan: the one from the Lower Estuarine Clay on Islandmagee, and the other from what is probably a fluviatile gravel intercalated between the Upper and Lower Estuarine Clays in the raised-beach formation at Cushendun.The former of these cultures has its counterpart in the blade industry beneath alluvium in the Orwell Estuary at Ipswich, Suffolk; whilst the latter finds its parallel in the raised-beach at Campbeltown in Argyllshire, Scotland. Adopting the familiar culture-sequence of Central Europe I had previously designated these two groups as phases of the Magdalenian period, but, in order to avoid confusion between the time-periods and the nomenclature of continental cultures, I have decided to base my chronology of the north Irish industries upon the natural changes of climate revealed by a study of the deposits in which they were found. The industries to be described below were contemporary with the Mesolithic Forest Cultures distinguished by Childe and Clark over the plain of northern Europe.

The results of the study of rare communities in the middle reaches of the Lena river valley, one of the most floristically rich regions of Yakutia, are presented. There are grow populations of 81 species of vascular plants listed in the regional Red Book. Populations of 35 species are covered by various types of protection. Five populations of endemic plants of the North-East of Russia, 13 species living on the northern limit of their ranges, and 3 endemic plants of the Central Yakutia were not included in protected areas (PAs). The relict steppe communities with Artemisia martjanovii Krasch. ex Poljak., Krascheninnikovia ceratoides (L.) Gueldenst., Hedysarum gmelinii Ledeb., Astragalus lenensis Shemetova, Schaulo et Lomon. are under threat of complete extinction.

Systematic Composition

The analysis of the distribution of plant remains in deposits of the Aigur and Toptan formations (Omsukchan district of the Magadan Region) showed that the main part of the species that were included in the Toptan stratoflora (Samylina, 1976), in fact come from the Aigur Formation. Floristic assemblages of the Aigur and Toptan formations are very similar in systematic composition. Increasing the diversity of flowering plants and reduction of typical Cretaceous taxa (cycadophytes and Ginkgoales was not indicated on the boundary between these formation. Thus, there is no evidence of significant changes in the floristic composition at this stratigraphic level and the existence of independent Toptanian stage in the evolution of the mid-Cretaceous flora of the North-East of Russia. Floristic assemblages from the Galimyi, Aigur and Toptan formations are proposed to be merged into a single Sugoi flora, which should be attributed to the Buor-Kemus stage of floral development (lower-middle Albian). The description of the lectostratotype of the Toptan Formation is first published and distribution of this formation is illustrated.

Classification of relic steppe communities in the Omolon valley (Western Chukotka) has been performed according to the Braun-Blanquet approach. All communities represent 3 associations, 3 subassociations, 3 variants and 15 communities of class Сleistogenetea squarrosae Mirk. et al. 1986, order Helictotrichetalia schelliani Hilbig 2000 and alliance Elytrigio jacutori—Dracocephalion palmati Sinelnikova 2009. The new association — Lychnido sibiricae—Festucetum kolymensis ass. nov. and two new subassociations — Thymo diversifolii—Elytrigietum jacutori festucetosum kolymensis subass. nov. and Dracocephalo palmati—Saxifragetum omolojensis eremogonetosum tschuktschori subass. nov. are described. Peculiarities of distribution of class Сleistogenetea squarrosae in the North-East of Russia are discussed.

Up to the present time it has usually been considered that almost all the cases of Human trypanosome disease in man in Nyasaland have been confined to a small area. This, the so-called Sleeping-Sickness District, has been described in a former paper, but it may be repeated here that it is the part of the “fly-country” lying along the western shore of Lake Nyasa, between S. lat. 13° 20' and 13° 50', and extending some twenty miles inland. Through the centre of this area a road runs from Domira Bay on the Lake into North-East Rhodesia. This road, until lately, was a principal highway between the coast and Central Africa. Dr. Aylmer May, the Principal Medical Officer of North-East Rhodesia, who lately visited Kasu, informed the Commission that it was along this trade-route that all the North-East Rhodesian, cases of Human trypanosome disease have occurred. It is said that some 25,000 native porters passed along this road every year, and as they entered a Glossina palpalis area at the Congo end of their journey, it seemed at first natural to suspect that the disease was true Sleeping Sickness, and had spread from west to east along this trade-route. This suspicion was shown to be groundless by the discovery that the parasite causing the disease in North-East Rhodesia and Nyasaland is not Trypanosoma gambiense , but a distinct and separate species giving rise to a totally different disease. The question then arose as to whether this was an imported or indigenous disease. It has, therefore, been one of the objects of this Commission to determine whether the trypanosome causing Human trypanosome disease in Nyasaland is restricted to the game and “fly” of the Proclaimed Area, or if it extends to the north and south along the “fly-belt.” If it is found to extend over all the “fly-area” in Nyasaland, then the disease is probably native to the soil and not an importation from Tanganyika or the Congo. But it will be well at this point to lay down definitely the various opinions or theories at issue. These are three in number.

Abstract Recent climate warming is thought to affect the migratory behavior and geographical range shifts of Pipistrellus nathusii. This bat of the European temperate woodland zone is known to migrate up to 1900 km between its breeding and wintering areas where it uses overground roosts for hibernation. New wintering areas of the species have been recorded lately mainly in the cities of Central Europe, largely extending its winter distribution to the north-east. The growing detection of the winter occurrence of P. nathusii has coincided with an increase in mean winter temperatures and urban warming. Our analysis shows that a winter isotherm of −2.5°C acts as a border for the winter occurrence of P. nathusii, and the species uses urban areas, most likely benefiting from the effect of urban heat islands. Accordingly, the island-like pattern of P. nathusii’s regular wintering habitats distribution in Central Europe seems to reflect the thermal and structural diversity of the environment. The use of diverse anthropogenic roosts suggests that the species is well-adapted to urban habitats, thus demonstrating its ecological plasticity.
