The ancient fortified settlement of Amnya I is a unique Early Neolithic site in the northern taiga zone of Western Siberia (Khanty-Mansi Autonomous Okrug, the Amnya river). It is located on a promontory and has three lines of defense and ten dwelling depressions. The structures of the excavated dwellings are very similar, though the artifact assemblage appears rather heterogeneous. We carried out a technical and technological analysis of ceramics, which showed no correlation between the texture, on the one hand, and the morphology and ornamentation of pots on the other one. Planiographic analysis of ceramics showed that vessels with comb and incising patterns are found in different dwellings, although there are objects in which both groups lie together. Various categories of stone implements (bladelets and polished arrowheads) also appear on different parts of the settlement. Most likely, the observed differences in the artefact complexes of objects are associated with the stages of the functioning of the settlement. The absolute chronology does not yet clarify the sequence of erection and existence of objects. New AMS date is probably vulnerable to a significant reservoir effect. The abundance of unsolved issues of absolute and relative chronology makes the resumption of research on this unique site urgent.

Northern taiga forests and subalpine plant communities of the Laplandskiy State Nature Biosphere Reserve (Kola Peninsula, Russia) were surveyed for myxomycetes. A total of 1675 specimens of myxomycete fruit bodies (sporocarps) were registered, among them 1584 records from field collections and 92 obtained from 210 moist chamber cultures of ground litter, bark of living trees, wood, and weathered dung of moose and willow ptarmigan. Most of 125 taxa (124 morphospecies and one variety) representing 34 genera were recorded only in the field (104 taxa from 32 genera), but some were exclusively obtained from moist chamber cultures (8 taxa from 5 genera). All of the recorded species are new for the Laplandskiy Reserve. Species numbers decreased among the four studied forest associations along the elevation and mositure gradient, and the Shannon index showed a similar trend: spruce forest (PICa; 84 taxa, H’=3.8), spruce-peat moss forest (PICb; 70, 3.5), dry spruce-pine forest (PIN; 62, 3.7), subalpine birch forest (SB; 30, 2.7). The estimated completeness of the survey according to the Chao1 estimator was 66%, indicating that most of the more common species should have been recovered. The trend among forest associations runs mainly parallel to diversity: PICa and PICb 83%, PIN 47%, SB 57%. The myxomycete assemblage of dry coniferous forests is the most distinctive among the three forest types and shows the highest number of indicator species. The overall degree of specialization of myxomycetes is higher for substrate type than for forest associations. Among substrate types, species diversity and richness increase from litter over bark to wood.

Living Organisms

The Onega Peninsula is located in the north-west of Russia in the Arkhangelsk Region, juts out into the White Sea, is located in an area of a transitional climate from an oceanic to a continental temperate climatic zone, belongs to the central sector of the northern taiga zone. The flora and fauna of the peninsula are very diverse. A significant part of natural complexes is highly preserved and is ideal for biosphere monitoring. In connection with intensive industrial logging on the peninsula, there is a need to identify rare species of living organisms and determine measures for their protection. The article provides data on the finds of habitats of 11 rare species discovered by the author during field routes along the Lyamitsky landscape in the period from 2009 to 2020. Finds of 10 out of 11 species have not been previously published. In 2020, the state of a group of individuals of 1 of 11 species that had not yet formed a stable population was reexamined, the find of which was previously published. This species (derbyanka spikate) is new for the Arkhangelsk and all adjacent regions and needs to be entered into the Red Book of the Arkhangelsk Region, which includes the remaining 10 species. 4 species of them are also included in the Red Book of the Russian Federation. The finds of the species belong to the lands of different purposes: to the forbidden zone of forests and to the lands of the forest fund leased by a logging company. The article discusses the number of discovered species and such a limiting factor as logging. The assessment of the feasibility of measures for the protection of species has been carried out. It was revealed that some of them (splachnums) increase in number due to felling, the number of others is not threatened by felling (common viper, etc.), to preserve the number of the third, special protection measures are required (pulmonary lobaria, truncated horn, etc.). The information obtained is processed cartographically using geoinformation technologies and can be used to replenish the database of the Red Book species and to organize their protection.

The Village

In the Murmansk Region floodplain meadows of class Molinio-Arrhenatheretea Tx. 1937 being there on the northern limit of distribution in Europe, rarely occur along the large rivers. The research with purpose of classification was conducted in lower stream of the Varzuga River, which is one of the largest (254 km long) river on Kola Peninsula. Few large islands are disposed in the lower course of the river. Riverbanks are formed mainly by sandstones and moraine deposits which prevent the formation of a vast floodplain formation; its the largest area is situated downstream the Varzuga village, that is one of the oldest settlements of Kola Peninsula, arisen in 15 century. The agriculture period on floodplains around the village has about 500 years of regular mowing and grazing. The river basin is located in the taiga zone. Adjacent spruce and pine forests belong to associations Empetro–Piceetum obovatae (Sambuk 1932) Morozova 2008 and Cladonio arbusculae–Pinetum sylvestris (Cajander 1921) K.-Lund 1967, bogs — to ass. Empetro–Sphagnetum fusci (Du Rietz (1921) 1926) Dierssen 1982. Ferns and tall herbs dominated birch forests occur on Varzuga River islands. Sandy beach vegetation of Ammophiletea Br.-Bl. et Tx. ex Westhoff et al. 1946 and halophytic marshes of Junceteamaritimi Br.-Bl. in Br.-Bl. et al. 1952 were described in the river mouth (Koroleva, 1999; Koroleva et al., 2011). Floodplain meadows (Fig. 1) were studied on the river banks and on islands from the Varzuga village to river mouth, in July and August in 2013 and 2015. 46 relevés were performed on sample plots mainly 10×10 m on the base of Braun-Blanquet approach. The syntaxa of high level are in accordance with latest survey by L. Mucina et al. (2016). Floodplain meadows belong to the alliance Astragalo subpolaris–Festucion rubrae all. nov. hoc loco (holotypus — Anthoxantho alpini–Geranietum sylvatici ass. nov. hoc loco) (Table 1) with following diagnostic species: Sanguisorba polygama, Dianthus superbus, Astragalus subpolaris, Oxytropis sordida, Myosotis asiatica, Veratrum lobelianum, Hedysarum arcticum, Senecio nemorensis, Allium schoenoprasum, Potentilla crantzii. Plant communities include mesophytic herbs, diagnostic species of classes Molinio-Arrhenatheretea and Mulgedio-Aconitetea Hadač et Klika in Klika et Hadač 1944, with group of species characteristic for tundra meadows (Dianthus superbus, Astragalus subpolaris, Oxytropis sordida, Bistorta vivipara and Potentilla crantzii). More than half of diagnostic species of alliance Astragalo subpolaris–Festucion rubrae have arctic, arctic-alpine and hypoarctic distribution. Two associations belong to this alliance: ass. Diantho superbi–Festucetum ovinae ass. nov. (Table 2; holotypus hoc loco — relevé 2 (186/13), Fig. 2) with diagnostic species Dianthus superbus, Thymus subarcticus, Campanula rotundifolia, Antennaria ­dioica, Calluna vulgaris, Festuca ovina, Nardus stricta, Viola canina, Potentilla crantzii, P. erecta, Sonchus arvensis, Pilosella laticeps. Low-herb meadows, being used as a pasture, occur mainly on higher and dryer habitats, than the next association. Ass. Antho­xantho alpini–Geranietum sylvatici ass. nov. (Table 3; holotypus hoc loco — relevé 17 (136/13), Fig. 3) includes regularly mowed tall-herb meadows formed after deforestation. Diagnostic taxa are Anthoxanthum alpinum, Geranium sylvaticum, Angelica sylvestris, Phleum pratense, Trollius europaeus, Anthriscus sylvestris, Cirsium heterophyllum, Vicia cracca. Ass. Filipendulo ulmariae–Deschampsietum cespitosae Shushpannikova et Yamalov 2013 of alliance Deschampsion cespitosae Horvatić 1930 (Table 4) was described in wet depressions near the village. Diagnostic taxa are Deschampsia cespitosa and Filipendula ulmaria. Community type Festuca rubra–Ligusticum scothicum of alliance Conioselinion tatarici Golub et al. 2003 (Table 5) occurs on the islands and in floodplain in the Varzuga river mouth. Diagnostic taxa are Ligusticum scothicum, Festuca rubra, Potentilla egedii, Primula finmarchica, Alopecurus arundinaceus, Calamagrostis neglecta, Lathyrus aleuticus, Carex lanceolata, Eleocharis palustris. Floodplain meadows of class Molinio-Arrhena­the­retea are rich of species, with about 140 vascular plants, 20 % of which occur with high constancy (more than 60 % of presence in at least one syntaxa), and 20 % with high cover (more than 5 % at least in one community). The composition of meadows reflects the habitats specific, with short spring flood, regular grazing and mowing, close neighboring of birch and pine forests, tundra zone and White Sea shore. These meadows are worth status of the special protected area «Floodplain meadows in the valley and islands of Varzuga River». If the idea of the National Park «Terskiy Bereg» is revived, the analyzed meadows are to be included in the protected area of natural and cultural heritage, with special regime of mowing and moderate grazing.
