In the present paper we describe and discuss belemnite finds from the basal part of the middle Jurassic sequence at the southwest of the Republic of Tatarstan (Tetyushi district). The belemnites were collected from the outcrops located along a shoreline of the Kuybyshevskoye reservoir (Volga river) between the place Tarkhanovskaya pristan and the former village Dolinovka. These belemnites indicate that the basal part of the Jurassic sequence is Early Bathonian (Ishmae Zone) or, less probable, Middle Bathonian in age. Such dating triggers a critical review for the age of the middle Jurassic sequence in the region. In particular, poorly preserved ammonites previously collected from the same outcrops higher in the succession and interpreted as members of the Late Bajocian subfamily Garantianinae, are in fact Late Bathonian Gowericeratinae. Consequently, Beds with Garantiana nominally the most ancient ammonite-based biostratigraphic unit within the whole Jurassic of European Russia, based on this assemblage, is invalid.

Abstract Population-based studies of endangered plant species are key methods for assessment of the status for these plants at any territory. Plant species of the Orchidaceae family are sensitive components in natural ecosystems. That is why determination of the status for their populations can be considered as indicators for the status of natural ecosystem position as a whole. Investigations of three Orchidaceae species populations (Orchis militaris L., Epipactis palustris (L.) Crantz, Malaxis monophyllos (L.) Swartz) were carried out in Central Russia (Republic of Mordovia). Abundance, density, structure and dynamics of populations of these species were studied. Species composition of accompanying flora was established for each rare species. Some morphometrical parameters of individuals for the studied species were measured. Features of ontogenetic spectrum for Orchis militaris and Epipactis palustris populations were shown.

The history of local government in South Africa dates back to a time during the formation of the Union of South Africa in 1910. With regard to the status of local government, the Union of South Africa Act placed local government under the jurisdiction of the provinces. The status of local government was not changed by the formation of the Republic of South Africa in 1961 because local government was placed under the further jurisdiction of the provinces. Local government was enshrined in the Constitution of the Republic of South Africa arguably for the first time in 1993. Under the interim Constitution local government was rendered autonomous and empowered to regulate its affairs. Local government was further enshrined in the final Constitution of 1996, which commenced on 4 February 1997. The Constitution refers to local government together with the national and provincial governments as spheres of government which are distinctive, interdependent and interrelated. This article discusses the autonomy of local government under the 1996 Constitution. This it does by analysing case law on the evolution of the status of local government. The discussion on the powers and functions of local government explains the scheme by which government powers are allocated, where the 1996 Constitution distributes powers to the different spheres of government. Finally, a conclusion is drawn on the legal status of local government within the new constitutional dispensation.

ArgumentThis paper analyses a process of co-construction of knowledge and its multiple forms of communication in a country of the European periphery in the early twentieth century. It focuses on Lieutenant Manuel Soares de Melo e Simas, a politically engaged Portuguese astronomer, who moved from amateur to professional during the political transition from the monarchy to the republic. Melo e Simas paralleled his professional career in continuous activity of communicating science to the public in the context of republicanism in a double way, by responding to the agenda of republicanism and by playing an active role in shaping it. He aimed at educating lay audiences in the various ways of astronomy, and he reached out to as many people as possible by exploring a multitude of communication channels, from lectures to articles in newspapers and journals. Voiced often within newly created republican institutions, the praxis and the ideas of Melo e Simas helped to mold the new republican scientific ethos. By going beyond mere emphasis on scientism and positivism, usually taken to be the defining characteristics of the new republican ethos, this paper argues that science and the specificities of its multiple forms of communication were central to the way Melo e Simas shaped the republican ideology. Furthermore, popularization of science was used to legitimize the status of professional scientists at the same time that it helped reinforce their institutional setting, still to be negotiated in the forthcoming decades through a complex process which deserves further historical analysis.

Abstract Background This study aimed to describe the status of alcohol consumption and drug use among young adults as well as their determinants. Methods We conducted a cross-sectional study of 356 young adults (aged 18 to 24 years) living in Palau in 2013. The prevalence of self-reported alcohol and marijuana usage were compared within and between sexes, age groups, ethnicities, and education levels. Results The proportion of current drinking was higher in people aged 21–24 than in those aged 18–20 (73.2% vs. 60.9%, p = 0.09 in men and 48.3% vs. 30.0%, p = 0.02 in women), while that of marijuana use did not differ between the age groups. The proportions of current drinking and marijuana use were higher in Palauan than in other ethnicities (current drinking: 70.6% vs. 40.6%, p = 0.005 in men and 38.8% vs. 16.6%, p = 0.04 in women; lifetime marijuana use: 80.0% vs. 52.9%, p = 0.02 in men and 56.1% vs. 30.6%, p = 0.09 in women). The proportion of frequent (3 times or more) marijuana users was higher for the lower educated than for the higher educated (62.5% vs. 32.1%, p < 0.001 in men and 33.9% vs. 24.4%, p = 0.12 in women). Conclusions Sex, age, ethnicity, and education were significant determinants of alcohol and marijuana use.

AbstractThe Republic of Guinea is thought to contain the largest population of common hippopotamus in West Africa. However, no systematic field survey has been carried out recently and the information available is limited to informal observations. To clarify the status of the common hippopotamus in Guinea, we carried out a biannual population survey along the section of the Niger River (the largest river in Guinea) within the Haut Niger National Park. We counted 93 hippopotamuses in 28 groups in the dry season and 77 hippopotamuses in 23 groups in the wet season. Mean group size and number of neonates did not change between the seasons. Hippopotomuses were more numerous along the river sections bordering uncultivated floodplains. This underlines the significance of this habitat (which is used as a grazing area) for conservation of this species. Haut Niger National Park is the most important protected area in Guinea for conservation of the common hippopotamus. Hippopotamus-human and -cattle conflicts in terms of floodplain use in the park's buffer zone should be closely monitored. Floodplain conversion to rice fields represents one of the most important threats to the long-term conservation of hippopotamus populations in Guinea.

The paper is part of a series of publications that set out to examine various aspects in the analysis of appositive constructions. The purpose of this particular study is to reveal the multidimensional, diverse, and complex interaction between three types of syntactic relations – attributive, predicative, and appositive. The study offers a critical review of various theories on the status of the grammatical relation between the components of non-detached (close) appositive constructions. The main argument of this paper is that determining this status, on the one hand, is a function of the morphological and semantic characteristics of the components of the construction, while, on the other hand, it determines their syntactic status.

Process of bird population restoration after fires was investigated in two protected areas in the Volga river basin in central Russia. Anthropogenic pressure in Kerzhensky and Mordovsky nature reserves is very low, it made possible to discover some characteristics of the process of bird population restoration in reference environment. The counts were carried out both in the affected areas of the reserves, and in unaffected parts. The studied area was in its five year after the fire. Dynamics of post fire bird population restoration and its dependence on both the age and history of the original ecosystems were investigated. The authors present the results of dominant species analysis and information about their distribution in the investigated natural reserves. The authors show peculiarities and proportions of ecological groups of birds in the studied territories as well as their proportion. The influence of hydrological parameters on bird communities composition was investigated, it turned out that post fire partial inundation leads to increase of waders of Gallinago and Tringa genera. Species diversity of bird communities in affected areas was considered. Using Pielous index it was found that species evenness remained relatively high, i.e. no significant increase of dominance was observed after the fires. The authors analyzed the composition of ornitocomplexes in terms of different faunistic groups.

Fossil chela of an erymid lobster from a single locality of the upper Bajocian in the Western Fore-Balkan Mts (NW Bulgaria) was studied. Two segments of the thoracic appendages, probably belonging to one individual, were described: 1) P1 propodus with partially preserved pollex and dactylus; and 2) P1 carpus and P1 merus attached. These elements of the first pair of pereiopods of a lobster were identified as Eryma compressum (Eudes-Deslongchamps, 1842). Eryma compressum a is well-known taxon from numerous Jurassic localities in Europe but has not been recorded in Bulgaria to date. Therefore, albeit being an isolated finding with only a few elements, the Bulgarian example contributes to the overall record of European erymid faunas from the Middle Jurassic, and especially in Eastern Europe, from where only a few erymids have been reported.
