For a comprehensive assessment of the habitats of rare and vulnerable lichen species, 4 key sites in theEltsovsky, Togulsky and Zarinsky districts of the Altai territory were studied. Plant communities – spruce forests, forests with spruce and cedar pine, as well as fir and aspen forests were described. Seven species of lichens listed in the Reddata book of the Altai territory (2016) were found in the studied forests: Graphis scripta, Lobaria pulmonaria, Nephromabellum, Ramalina roesleri, R. sinensis, R. vogulica, and Usnea longissima. Ecological preferences are indicated for eachspecies, and the population density is calculated.

Key Sites

The long-term soil temperature monitoring in the area of more than 550 km in length within the region of Transbaikalia has been carried out. Sites for the monitoring were represented by the forest-steppe vegetation of different ecotopological and ecogeographical patterns. It was revealed that the dynamics of temperature regimens are highly synchronized reflecting the macroclimatic unity of the region. The sufficiently higher heat supply on the southerly exposed slopes comparing to northerly exposed ones was demonstrated. The distinctness between soil temperature regimens in different sites was revealed and attributed to the size of forested patches within the forest-steppe landscape, as well as discrepancies between eco-geographical features of sites along the sublatitudinal gradient. Differences between the vegetation types that occurred on the northern and southern slopes as well as between key sites scattered throughout the region were underlined. These differences are suggested to be connected with the spatial differentiation of the soil temperature. It was established that vegetation on the southern slopes is relatively more homogeneous being related to the single class Cleistogenetea squarrosae, while on the northern slopes plant communities related to three classes were developed, namely steppe class Cleistogenetea squarrosae, and two forest classes – Rhytidio-Laricetea and Vaccinio-Piceetea.

AbstractAn overview of the salt-marsh herbland and scrub vegetation belonging to the class Salicornietea fruticosae Br.-Bl. et Tx. ex A. Bolòs y Vayreda 1950 in Apulia is presented. Data available from literature have been supplemented with original relevés performed in different locations of the Apulia region. On the basis of a total of 297 relevés, fifteen communities have been defined, according to the traditional phytosociological system based on dominant and/or diagnostic taxa. For comparison purposes, the salt-marsh vegetation has been classified using numerical methods. The results obtained show that most of the clusters correspond to specific associations, and confirm the division into vegetation alliances and orders. Numerical analysis also allowed us to assign the proper allocation of some associations and plant communities drawn from literature. Five alliances, with plant communities characterized by specific ecological features, have been discriminated: Sarcocornion alpini and Arthrocnemion glauci (lower marshes), Salicornion fruticosae (middle marshes), Inulion crithmoidis and Suaedion brevofoliae (upper marshes). In addition, during the field work, a population of Halocnemum strobilaceum (Arthrocnemo-Halocnemetum strobilacei), new record for the Apulia region, has been found.

<p>The mycology of peatlands, with their specific plant communities and numerous rare plant species, has been underexplored and is poorly recognized. The main objectives of this study were to identify the species richness and diversity of macromycetes in raised and transitional bogs of Pomerania and to establish correlations between macroscopic fungi and peatland communities occurring in the area in view of environmental conditions. Investigations spanning a period of ten years were conducted at 134 sites (71 raised and 63 transitional bogs) in eight non-forest peatland communities (<em>Caricetum lasiocarpae</em>, <em>Caricetum limosae</em>, <em>Caricetum rostratae</em>, <em>Eriophoro angustifolii-Sphagnetum recurvi</em>, <em>Rhynchosporetum albae</em>, <em>Erico-Sphagnetum medii</em>, <em>Sphagnetum magellanici</em>, and the <em>Eriophorum vaginatum-Sphagnum fallax</em> community) and two forest communities (<em>Vaccinio uliginosi-Pinetum</em> and <em>Vaccinio uliginosi-Betuletum pubescentis</em>) in which 108 permanent observation plots were established for detailed examinations. A total of 191 macromycete species were recorded in the peatlands. The smallest number of species was recorded in <em>Rhynchosporetum albae</em> (12 species) and <em>Caricetum rostratae</em> (15 species). Phytocoenoses richest in fungi were <em>Vaccinio uliginosi-Pinetum</em> (102 species) and <em>Vaccinio uliginosi-Betuletum pubescentis</em> (121 species). The number of macromycete species recorded in individual peatland communities depends on the community type and is not conditioned by the number of observations and the number and the total area of permanent plots. Five mycosociologico-ecological groups of macroscopic fungi were distinguished based on numerical analyses. Four groups comprise species of fungi associated with a specific phytocoenosis or a group of phytocoenoses. One group consists of fungi with a broader ecological scale. The majority of environmental variables representing the substrate’s chemical properties, humidity and pH show a statistically significant influence on the diversity of macroscopic fungi species in the peatland communities. Cartogram maps of the distribution of 21 species of peatland fungi are included and geographico-ecological features of the species are briefly described.</p>

&lt;p&gt;Forests plants affect the biological and chemical properties of the soil through the root exudation, input of leaf and root litter. This study investigates the relationships between the species composition of plant communities, microbial properties and content of elements of the upper soil horizon in boreal forest ecosystems (using NMS analysis).&lt;/p&gt;&lt;p&gt;It is hypothesized that 1) microbial biomass and chemical properties relates to the species diversity of plants, 2) microbial biomass and chemical properties relates to certain plant communities, 3) microbial biomass and chemical properties linked to altitude gradient, 4) types of communities differ due to the composition of the grass cover.&lt;/p&gt;&lt;p&gt;Plots were chosen in the foothills of the Ural Mountains, Russia, in Pechoro-Ilych Nature Reserve, 62-63&amp;#176;N, 58-59&amp;#176;E, to small altitude gradient 250-400 m above sea level. Plant, litter and soil were taken from five spruce - fir forests (Picea obovate together with Abies sibirica) with siberian pine and birch (hereinafter &amp;#8220;spruce forest&amp;#8221;). The peculiarity of the territory is that in a small area five different grassy communities were formed.&amp;#160; They represented by both species-rich tall grasses forests and poor species, moss and large fern forests.&lt;/p&gt;&lt;p&gt;Types of forests: boreal-tall grass (3 plots), small grass &amp;#8211; green moss (3 plots), bilberry-green moss (3 plots), shrub - haircap moss (4 plots) and large fern (3 plots). The plots (10&amp;#215;10 m) were selected for plant biodiversity describing. Topsoil samples (0-5 cm) were taken from sub-plots in July 2018 (n=48). In the collected samples, microbial biomass carbon (MBC), basal respiration (BR), pH and content of elements (S, P, Ca, Mg, K, Si, Ti, Mn) were measured.&lt;/p&gt;&lt;p&gt;We distinguished a group of communities with high microbial biomass (small grass-green moss and boreal-tall grass spruce forests) and a group with low microbial biomass (shrub-long moss, bilberry-green moss, large fern spruce forests). The high biological activity of the soil is weak confined to plant communities.&lt;/p&gt;&lt;p&gt;No strong relationship between MBC, BR, plant species richness and altitude was found.&lt;/p&gt;&lt;p&gt;Microbial biomass is strongly related to species of boreal-tall grasses (Aconitum septentrionale Koelle, Crepispaludosa (L.) Moench, Rubussaxatilis L., Thalictrum minus L., Valerianaofficinalis L., Filipendulaulmaria (L.) common species, Geranium spp. Species L.) albiflorumLedeb., Paris quadrifolia L.). These types of grass indicate an increase in soil pH, increase the content of Ca, Mg and S in the soil, and a decrease the content of Si and Ti. Opposite, the content of Si and Ti increased in the moss communities. K increased in the soil of large fern and boreal-tall grass communities. Thus, the content of microbial biomass, S, Ca, Mg, pH increased together in the direction of boreal tall grass community. The research was financial supported by grant RFBR mol_a No. 18-34-00987.&lt;/p&gt;

Quercus Rotundifolia

The holm oak woodlands as ecotonic phytocoenoses occur under different ecological conditions, and frequently representing the climax of edaphoxerophilous series of crests and siliceous rocky areas. In this paper we study the floristic, ecological, and biogeographical differences of the edaphoxerophilous holm oak woodlands of the southwestern Iberian Peninsula, included in the Querco rotundifoliae-Oleenion sylvestris suballiance. Our phytosociological (Braun–Blanquet methodology) and numerical analysis (hierarchical cluster analysis) of three formerly described association and our own samples lead us to propose a new association: Ulici argentei-Quercetum rotundifoliae, growing mostly on semihyperoceanic Monchique Sierran Biogeographic District, on rocky slopes and outcrops derived from schists and greywackes. Moreover, we present an overview of ecological features and the diversity of plant communities occurring in the serial dynamic of the thermophile holm oak woodlands of the southwest of the Iberian Peninsula.
