Riccia marginata Lindb. was described by S. O. Lindberg (1877) from the outskirts of the town of Sortavala near the north shore of Lake Ladoga, Republic of Karelia, Russia. The species has been forgotten in most recent liverwort accounts of Europe, including Russia. Lectotypification of R. marginata is provided. R. marginata shares most characters with R. beyrichiana Hampe ex Lehm. It differs from “typical” plants of R. beyrichiana in having smaller spores, with ± distinctly finely areolate to roughly papillose proximal surfaces and a narrower and shorter thallus, as well as in scarcity or absence of marginal hairs. It may represent continental populations of the suboceanic-submediterranean R. beyrichiana, known in Russia from the Leningrad Region and Karelia only. The variability of spore surfaces in R. beyrichiana is discussed and illustrated by SEM images. A comparison with the spores of R. bifurca Hoffm. is provided. The question how distinct R. marginata is from R. beyrichiana needs to be clarified by molecular studies in the future, when adequate material is available. R. marginata is for the time being, provisionally, included in R. beyrichiana.

The Town

Lindfield was originally the traditional land of the Kuringgai (also spelt Guringai) people. It is located on the north shore, 13 kilometres from central Sydney. The name for the railway station and suburb was taken from Lindfield, meaning a clearing in the lime forest, the name of the cottage built by early resident, Francis John List, in 1884 and later moved to Narrabeen. It is assumed that the house was named after the town of Lindfield in Sussex, England. The suburb is bordered by Treatts and Stanhope roads, Garigal National Park, Carnarvon Street, Chelmsford Avenue and Waimea Road to the east of Pacific Highway, and Bayswater and Provincial roads and Lane Cove National Park to the west. It has an area of 517 hectares.

The Crimean Peninsula

The situation in the ecology of the Crimean Peninsula in recent years was discussed in the article. The analysis of absolute and integrated indicators of the anthropogenic impact showed that the ecological situation remains difficult, and according to some indicators even continues to deteriorate. In summer 2018, the situation had worsened because of the large chemical release of titanium dioxide on the north of the Crimea from the holding pond of a large Russian plant that is situated near the town of Armyansk. This, in turn, led to the contamination of the large territory on the north of the peninsula. This fact indicates insufficient control by officials of the Republic of Crimea over the implementation of the RF laws for environmental protection by business owners of various forms of ownership, especially private ownership, the level of responsibility for the environment of which is very low.

This chapter is a transcript of Haq’s address to the North South Roundtable of 1992, where he identifies five critical challenges for the global economy for the future. If addressed properly, these can change the course of human history. He stresses on the need for redefining security to include security for people, not just of land or territories; to redefine the existing models of development to include ‘sustainable human development’; to find a more pragmatic balance between market efficiency and social compassion; to forge a new partnership between the North and the South to address issues of inequality; and the need to think on new patterns of governance for the next decade.

Specific Sequences

We employ social network analysis of collar decoration on Iroquoian vessels to conduct a multiscalar analysis of signaling practices among ancestral Huron-Wendat communities on the north shore of Lake Ontario. Our analysis focuses on the microscale of the West Duffins Creek community relocation sequence as well as the mesoscale, incorporating several populations to the west. The data demonstrate that network ties were stronger among populations in adjacent drainages as opposed to within drainage-specific sequences, providing evidence for west-to-east population movement, especially as conflict between Wendat and Haudenosaunee populations escalated in the sixteenth century. These results suggest that although coalescence may have initially involved the incorporation of peoples from microscale (local) networks, populations originating among wider mesoscale (subregional) networks contributed to later coalescent communities. These findings challenge previous models of village relocation and settlement aggregation that oversimplified these processes.

The Future

Tropical Cyclones (TCs) and Easterly Waves (EWs) are the most important phenomena in Tropical North America. Thus, examining their future changes is crucial for adaptation and mitigation strategies. The Community Earth System Model drove a three-member regional model multi-physics ensemble under the Representative Concentration Pathways 8.5 emission scenario for creating four future scenarios (2020–2030, 2030–2040, 2050–2060, 2080–2090). These future climate runs were analyzed to determine changes in EW and TC features: rainfall, track density, contribution to seasonal rainfall, and tropical cyclogenesis. Our study reveals that a mean increase of at least 40% in the mean annual TC precipitation is projected over northern Mexico and southwestern USA. Slight positive changes in EW track density are projected southwards 10° N over the North Atlantic Ocean for the 2050–2060 and 2080–2090 periods. Over the Eastern Pacific Ocean, a mean increment in the EW activity is projected westwards across the future decades. Furthermore, a mean reduction by up to 60% of EW rainfall, mainly over the Caribbean region, Gulf of Mexico, and central-southern Mexico, is projected for the future decades. Tropical cyclogenesis over both basins slightly changes in future scenarios (not significant). We concluded that these variations could have significant impacts on regional precipitation.

This forum builds on the discussion stimulated during an online salon in which the authors participated on June 25, 2020, entitled “Archaeology in the Time of Black Lives Matter,” and which was cosponsored by the Society of Black Archaeologists (SBA), the North American Theoretical Archaeology Group (TAG), and the Columbia Center for Archaeology. The online salon reflected on the social unrest that gripped the United States in the spring of 2020, gauged the history and conditions leading up to it, and considered its rippling throughout the disciplines of archaeology and heritage preservation. Within the forum, the authors go beyond reporting the generative conversation that took place in June by presenting a road map for an antiracist archaeology in which antiblackness is dismantled.

Set Up

Early in 1963 much of the land occupied by the Roman building at Fishbourne was purchased by Mr. I. D. Margary, M.A., F.S.A., and was given to the Sussex Archaeological Trust. The Fishbourne Committee of the trust was set up to administer the future of the site. The third season's excavation, carried out at the desire of this committee, was again organized by the Chichester Civic Society.1 About fifty volunteers a day were employed from 24th July to 3rd September. Excavation concentrated upon three main areas; the orchard south of the east wing excavated in 1962, the west end of the north wing, and the west wing. In addition, trial trenches were dug at the north-east and north-west extremities of the building and in the area to the north of the north wing. The work of supervision was carried out by Miss F. Pierce, M.A., Mr. B. Morley, Mr. A. B. Norton, B.A., and Mr. J. P. Wild, B.A. Photography was organized by Mr. D. B. Baker and Mrs. F. A. Cunliffe took charge of the pottery and finds.

Asymmetrical Power

AbstractNegotiators for powerful, self-reliant states tend to be less responsive to weak states relative to domestic constituents, while negotiators for states entangled in ties of asymmetric interdependence with more powerful states tend to be more responsive to the demands of powerful states than to the demands of domestic constituents. Asymmetrical power does not necessarily lead to asymmetrical results, however, because negotiators in weaker states may, nevertheless, have more attractive non-agreement alternatives and a longer shadow of the future. Negotiators with attractive non-agreement alternatives will be more willing to put agreement at risk by withholding concessions in the negotiation process. Centralized and vertical institutions are often a bargaining liability precisely because weak states tend to be less responsive to domestic constituents, whereas divided government can be a major asset. These propositions are demonstrated through an analysis and reconstruction of the North American Free Trade negotiation process.
