Calcareous and siliceous microorganisms are common components of mudrocks, and can be important in terms of stratigraphy and environmental interpretation. In addition, such microorganisms can have a significant ‘after life’, through post-mortem alteration, and represent a potential source of additional information about the diagenetic and deformation history of the rock unit. Some examples of the latter are illustrated in this study from foraminifera within a Cretaceous black shale of Colombia. This includes foraminifera tests acting as understudied repositories of authigenic calcite cement, and of elements such as Ba, Zn, Fe and S through the formation of baryte, sphalerite and iron sulphides (pyrite, marcasite). Such repositories, within the body chambers of foraminiferal tests, can provide important windows into the diagenetic processes within mudstones. If calcite cement is not recognised or separated from biogenic calcite, the depositional calcite budget can be easily overestimated, skewing the application of mudrock classification schemes, and affecting environmental interpretation including that of productivity. The elements Ba, Zn and Fe (often in ratio with Al) are commonly utilised as geochemical proxies of environmental parameters (productivity, bottom water redox conditions, etc.). Therefore, the presence of significant amounts of baryte, sphalerite and pyrite-marcasite (within foraminifera) should be noted and their origins (source and timing) investigated based on their spatial relationships before making environmental deductions based on geochemical analysis alone. Additionally, commonly observed marginal shell damage of many of the observed foraminifera is reported. We interpret this damage, for the first time, as an indicator of lateral dissolution, brought about by horizontal foreshortening during orogenesis. This is also supported by the occurrence of microscale anastomosing horizontal to inclined baryte-filled fractures within the mudstone matrix.

The spionid polychaete Dipolydora armata, a borer in calcareous substrata, is recorded for the first time from Belize, Brazil, Taiwan, and Vietnam. Specimens from these and other localities, as well as the type material of Polydora armata from Madeira Island and Polydora rogeri from the Mediterranean were examined and all the specimens were considered to be conspecific. Dipolydora armata is up to 8 mm long (usually 2–3 mm), with up to 45 segments (usually 25–35 segments), an incised prostomium, caruncle until the end of segment 2, up to 10 pairs of branchiae from segment 7, up to 20 awl-like modified spines per notopodium in up to 15 posterior segments, bilobed or cup-shaped pygidium, hooded hooks from segment 7 accompanied by capillaries throughout the body, major falcate spines of segment 5 with a large lateral tooth and an apical structure covered by fine bristles and appearing as a cowling or third tooth on the convex side of the main fang.  The life history of the species includes a period of asexual reproduction by architomy beginning soon after settlement, then sexual maturation and continuous breeding within an extended period with production of lecithotrophic larvae developing entirely inside egg capsules. Once mature, individuals probably reproduce only sexually and do not undergo additional architomic divisions.  Asexual reproduction results in high morphological variability of adult individuals, particularly in number, size, and arrangement of awl-like spines in notopodia. Polydora rogeri is placed into synonymy of D. armata. The original interpretation of the relationship between the polychaetes and the excavating sponge Cliona viridis as mutualistic symbiosis is discussed. Dipolydora armata is considered to be a widespread non-specialized borer perforating various calcareous substrata.

ABSTRACT Trachycephalus cunauaru is an Amazonian hylid that uses phytotelmata to reproduce. There is relatively little information about the species, mainly due to the difficulty of accessing their reproductive sites. In this study, we gathered data on the ecology and natural history of T. cunauaru in the southern Amazon, in the state of Mato Grosso, Brazil. In addition to natural phytotelmata, we used buckets installed at a height of 10 m as artificial phytotelmata. We compared physical and chemical characteristics, as well as the presence of tadpoles between natural and artificial phytotelmata. We also collected data on the reproductive behavior of the species through the use of camera traps. We recorded a density of 14.1 reproductive sites per km². Environmental parameters differed significantly between artificial and natural phytotelmata. In artificial sites, the presence of tadpoles was directly related to trees with a larger diameter. We registered oophagy for the first time for the species and observed that males can use more than one phytotelm. We also recorded the presence of snakes within the reproductive sites. We determined that artificial sites and digital camera traps are a satisfactory alternative for behavioral observations of T. cunauaru and possibly for other species with a similar habit.

The subject of this research is the history of the first of country-style resort appeared on the South Coast of Crimea at the turn of the XIX – XX centuries on the lands of country estates of New Mishor belonged to Shuvalov-Dolgorukov family. The phenomenon of country-style construction on the South Coast of Crimes, which starting point was the foundation of the Novyi Mishor, is viewed in the context of the processes of economic and sociocultural modernization of Russian society, formation of self-identification mechanisms of the emerging “middle class”, and new urban culture. Special attention is given to the period from 1917 to 1920, when the cultural figures left the capital and resided in the villages of Novyi Mishor. Based on examination the body of historical sources, many of which introduced to the scientific discourse for the first time, the author formed the database of villages and countryside residents of Novyi Mishor. A vast array of archival funds, reference literature, sources of personal provenance (memoirs, correspondence), and visual sources was attracted in the course of research. The novelty of consists in establishment of identities and social status of the residents of country resort of Novyi Mishor, determination of a range of sources for its further research, reconstruction of chronology of the development of this resort, details of everyday life and mentality traits of the residents, among which were the prominent figures of culture and art of Russia of that time – writers, actors, painters, scholars, and philanthropists.

The article describes the results of a codicological study of the Inventory of the Kirillo-Belozersky (St. Cyrill of Beloozero) Monastery (1615). The main codicological problem for the researchers posed by this monument is its numerous and asynchronical edits. It is possible to identify edit layers by studying the ink by means of spectrosonal imaging in near-IR wavelength region of the spectrum. This method is based on the property of inks (except those with a carbon base) to acquire transparency beyond the visible region of the spectrum (after 700 nm). As additional information, visually observed (in natural indirect daylight) color differences between inks have been used, as well as color estimation using a digital portable microscope Dinolite with Dinoscope software. As a result of the study, the main stages of work on the Inventory have been established. A significant part of the marginalia are in the same ink and handwriting as the main text: brown, with moderate transparency in near-IR wavelength region. Thus, the text was probably supplemented in the course of creation. This edit was accompanied by the text on the insert sheets made in ink that is slightly translucent in the IR region of the spectrum and has a dark brown color. The same ink was used in the main text of the manuscript. When the main text was rewritten in 1616-1617, it was compiled in a codex and significantly revised for the first time. The marker of this revision stage is light brown and yellowish-brown ink with high degree of transparency in IR wavelength region of the spectrum. In addition to the editing, the notebooks are numbered in the same light brown ink. The edit of this layer mainly included clarifications to the items description. The next significant revision of the inventory text, marked with brown ink that has low transparent in the IR wavelength region of the spectrum, refers to the period after July 22, 1621. Most of these edits, as well as the earlier ones, were devoted to clarifying descriptions, to clarifying location of objects, and to describing the monastery’s acquisitions and losses. Apparently, the later stage of editing is associated with the use of gray-brown ink, similar in spectral behavior to the ink of the main text. The record of the contribution of Prince Khvorostinin made in 1622–23 was written in this ink.

What makes this study topical: the urgency of the problem under consideration is due to the existing need for structural and semantic analysis of complex sentences (CS) with homogeneously collateral subordination of clauses, in different functional styles of speech and language. Our study is directed towards revealing the ability of syntaxemes with homogeneously collateral subordination to render hidden meanings of the author‘s ‘I’ and to thereby affect the reader/hearer. The cornerstone research method in this study is direct observation of language phenomena with generous borrowings from transformational analysis; it allows us to assert that the multi-component sentences under scrutiny here possess powerful expressive potential and can better than any other render additional information, thereby giving a strongly suggestive focus to an utterance or statement. In this paper, for the first time in the history of linguistics, we reveal how CS with homogeneously collateral subordination of sub clauses work in all functional styles. We also define cognitive boundaries within which takes place the choice between such multi-component structures in the process of language activity, with concern for how the ‘I’ of the author affects the addressee.

The paper is devoted to the generalization and characterization of random finds from the territory of the Charyshsky district of the Altai Territory. The summary includes both previously published items and new artifacts, information about which was received by the authors during the archaeological research of the Ust-Teplaya burial ground in 2020. The collection of artifacts published for the first time consists of three items. This is a double-headed iron psalium with sculptural design of the tips in the form of the heads of mythical birds with an elongated beak, a horn double-headed psalium and a bronze knife with a ring pommel. These items supplement the body of random finds from the area under consideration, which includes items already published in the scientific literature, such as stone drilled axes belonging to the Afanasyevo culture of the Eneolithic era of the 31st — 27th centuries BC, stone mace pommel and bronze dagger of the early and Middle Bronze period of the 22nd — 15th centuries BC and bronze bits of the Early Scythian time of the 8th — 6th centuries BC. The paper also presents the results of X-ray fluorescence analysis of a metal knife and bit, which showed that the objects were cast from a copper-tin alloy. The analyzed artifacts, random finds from the territory of the Charyshsky district of the Altai Territory, reflect various historical and cultural stages of the development of the population of Northern Altai. The artifacts add to the collection of archaeological sources on the ancient history of the region, from the Eneolithic to the early Middle Ages inclusively.

The threat assessment of Finnish species was carried out during 2017–2018 for the third time using International Union for Conservation of Nature (IUCN) criteria (IUCN 2012a, IUCN 2012b, IUCN 2016). The Red List was published in March 2019 (Hyvärinen et al. 2019). In conjunction with the assessment of threatened species, 36,602 species or lower taxa were listed. The information was sufficient for assessment of 22,418 species. It was done by 18 expert groups of different organism groups. The process was coordinated by the Finnish Environment Institute Syke and led by the steering group of the assessment from the Ministry of Environment. For the first time, the Finnish Biodiversity Information Facility FinBIF offered a documentation tool and archive for the threat assessment. The assessment was based on the national checklist of Finnish species coordinated by FinBIF. Many of the expert groups are in active collaboration with FinBIF in maintaining FinBIF’s taxon database and in updating the checklists. Hence, there was a good foundation to build on in developing the cooperation further and deepening the integration of the Red Listing process into FinBIF’s IT infrastructure. The documentation tool of the assessment is implemented in the taxon database of FinBIF (Fig. 1). The Red List data of the 2010 (all species) and 2015 (birds and mammals) assessments are readily available in the tool. The assessor can therefore easily copy and confirm e.g. area of occupancy, extent of occurrence, generation length and habitat of a species, if there is no need for editing. The service offers the possibility to add notes to most of the fields separately and commenting on the assessment by other authorized users. The tool archives the history of all changes. In line with the IUCN instructions, the tool automatically chooses the criteria leading to the highest possible threat category of criteria A-E filled out for each species. However, the assessor confirms the final evaluation. Finally, in several fields, the tool automatically checks the validity of values entered, e.g. criteria, threat category, length of the observation period, causes of threat, and current threat factors. The tool includes necessary fields for back-casting the categories of previous assessments to count the Red List Index. There is also a possibility to add or choose references for the assessment of a certain species in the publications part of the taxon database. Due to linkage through the taxon database, the updated threat categories of each Finnish species are immediately available as additional information of each species introduced in FinBIF. Also for the first time, the results of the threat assessment can be examined online directly after its publication at the Red List online service through FinBIF: https://punainenkirja.laji.fi/en. The online service makes Red List categories and related criteria searchable. Data can be categorized also by habitat, causes of threat, or current threat factors. Due to the ability to conduct searches, the online service supplements the printed book (Hyvärinen et al. 2019), which includes extensive summaries for groups of organisms.

The Way

Benjamin Franklin's enunciation of his so-called ‘one-fluid’ theory of electricity in the period 1747–55 nas often been hailed as an important milestone in the history of physics. So indeed it was, for, with the rapid and widespread acceptance of the new theory, the science of electricity became based for the first time on the view that the electrification of a body involved the accumulation of a ‘charge’ from elsewhere, rather than the excitation of matter already present in the body. Only a little more remotely, the triumph of Franklin's theory over the rival ‘excitation’ theory espoused by the Abbé Nollet paved the way for the more sophisticated fluid theories propounded by Aepinus, Cavendish, and Coulomb in the years that followed.
