Soil invertebrates occurrences in European North-East of Russia.

BackgroundThe European North-East of Russia is the territory which includes the Nenets Autonomous District, represented by the East European tundra (from Kanin Peninsula to Vaigach Island), Komi Republic with its taiga ecosystems and the Urals (Northern, SubPolar and Polar). Over 20 years of systematic studies of soil fauna in the studied region has resulted in a huge amount of data being accumulated that can be analysed from different positions. Considering that the representation of Russian soil biota data, especially from European North-East of Russia in the GBIF database is not large, our data are of great interest to the scientific world community. The accumulation of such data will solve questions on national and global scales using large arrays.This study produced a dataset containing information on occurrences on soil invertebrates (Lumbricidae, Chilopoda, Diplopda, Collembola, Elateridae and Staphylinidae) in the European North-East of Russia. The dataset summarises occurrences noted in natural and disturbed forests, tundra and mountain ecosystems.New informationData from 196 geo-referenced localities of European North-East of Russia (tundra, taiga and mountains ecosystems) have been collated. A total of 5412 occurrences are included in the resource. The current project surveys 13 species of earthworms, 20 species of millipedes, 246 species of springtails, 446 species of rove beetles and 60 species of click beetles. The diversity of soil invertebrates in the European North-East of Russia has not been fully explored and further exploration will lead to more taxa.

Bryophytes Occurrences Dataset Based On SYKO Herbarium Moss Collection.

BackgroundThe dataset with 49,726 bryophytes occurrences (49,261 moss occurrences and 465 liverworts occurrences), located predominantly on the territory European north-east Russia, is described in this data paper. The dataset was based on the digitised moss labels from the Institute of Biology of Komi Scientific Сenter of the Ural Branch of the Russian Academy of Sciences herbarium (SYKO). The information from the labels was recognised, cleaned and brought into compliance with the Darwin Core. More than 99.9% of occurrences were georeferenced with a precision of at least 3 km. For each occurrence, the original label image URL was given. The dataset contains occurrences of 539 moss and liverworts taxa (species and lower ranks) belonging to 190 genera and 75 families.New informationInformation about 49,726 bryophytes occurrences was published in GBIF. The dataset was based on label data of 94% of SYKO herbarium moss collection specimens.

A checklist of the flowering plants of Komi Republic (northeast of European Russia) and their representation in BOLD and GenBank databases

We presented the updated list of flowering plants (Angiosperms) of the Komi Republic that comprises 1211 taxa (including subspecies), 401 genera, and 80 families. This checklist based on the authors field collections data, materials from the Scientific Herbarium of the Institute of Biology of the Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences, published data and open-access databases. For each taxon of flowering plants, we provided a presence-absence checklist of nucleotide sequences (rbcL,matK, ITS2 andtrnH-psbA) that is available in BOLD and GenBank databases of DNA barcode data. The presented dataset will promote the identification of potentially new species (including endemic taxa) for molecular taxonomy and including of new sequences into the global database of BOLD Systems using the regional flora as model object.

Abundance of <i>Ixodes persulcatus</i> ticks in Komi Republic as a function of an air temperature

The sharp rising incidence of tick-borne encephalitis (TBE) in Komi Republic at the North-east of European Russia was recorded last decades. Tick-bite incidence also was grown. Rapid rise of TBE incidence growth and Ixodidae ticks depends on a number of factors, and the impact of climate change being one of them. Ixodes persulcatus ticks is considered as a main vector of TBE in Komi. Our objective is to estimate the influence of air temperature change on the tickbite incidence and Ixodes persulcatus population in Komi. Komi Republic is located near the Polar circle where the northern frontier of Ixodes persulcatus ticks situated and we expected the growth of tick’s population. The number of Komi inhabitants seeking medical care after tick bites in 1992–2014 was considered. Gridded monthly air temperature data with grid size 0.5 degree were recalculated to temperature referred to Komi administrative units. The time series of annual number of tick victims from 1992 till 2014 and model air temperature from 1948 till 2016 for all Komi administrative units were compiled. We analyzed the data on tick-bite incidence in Komi administrative units in relation to changes in local annual average air temperature within the study area. The linear dependence of the tick-bite incidence on air temperature was established when of the tick-bite incidence is represented in logarithm form. The tick population depends not only on temperature but humidity, landcover and hosts. Described areas of Komi belong to humid climate, where precipitations exceed evaporation. Most of the Komi territory is covered by taiga with underwood, grass and bush. Hosts of the first and the major levels are represented by birds and rodents. The dependence of tick-bite incidence and temperature looks like “Malthus’s law”, but the development of population depends on temperature not on time. The exponential growth in the nearest future will ceased and the population will proceed to stable phase. Ticks population in Komi Republic is moving to the North and the air temperature determines the dynamics of population.

Diatoms in epixylon of waters in the European North (Komi republic, NAO)

The results of studying the diatoms in epixylon of 15 water objects in European Northeast of Russia are presented. The samples of nature biofilms from external surfaces of submersed branches of Betula nana, Salix spp., woody snags, and wood debris were investigated. A comparative analysis of diatoms in fouling of woody substrates was carried out from coal-mine settling pond, lakes, streams, and different parts of mountain river. These are in the basins of Ortina, Vorcuta, More-Yu, Vychegda, Izhgma, Shchugor rivers. In stagnant waters diversity of diatoms form 9–56, in waterways 10–102 taxa. Encyonema minutum (Hilse) Mann, Navicula radiosa Kützing, Tabellaria flocculosa (Roth) Kützing were most frequently. A small degree of diatoms similarity in epixylon with other communities was revealed; the Sørensen coefficient is 0,3–0,4. Part of the diatoms with an abundance 3–6 points (28 taxa) were found only in one water bodies. Among them, in thermokarst lakes with low salinity water and a weakly acid reaction halophobic, acidophilic Eunotia microcephala Krasske, Kobayasiella subtilissima (Cleve) Lange-Bertalot, and Cymbella borealis Cleve prevail. In the coal–mine settling pond dominating group is represented by the alkaliphilic, halophilic Diatoma tenuis C. Agardh, Nitzschia clausii Hantzsch, and Gomphonema productum (Grunow) Lange-Bertot et Reichardt. Mountain streams are distinguished by the development of rheophilic Meridion circulare (Grѐville) C. Agardh, Diatoma mesodon (Ehrenberg) Kützing, Encyonema reichardtii (Krammer) Mann, Fragilaria gracilis Oestrup, Fragilariforma virescens (Ralfs) Williams et Round, Gomphonema montanum (Schumann) Grunow, G. pumilum (Grunow) Reichardt et Lange-Bertalot, G. ventricosum Gregory, Hannaea arcus (Ehrenberg) Patrick var. arcus et f. recta (Cleve) Foged. The composition of the epixylon dominant complexes also differs depending on the hydrological conditions and characteristics of aquatic environment. These differences in this community determine the significant diversity of this group of algae as a whole. In total, 244 species with intraspecific taxa from 67 genera and 27 families identified, and a large number of rare species found.

Mosses of spruce “island” in the valley of the More-Yu River (Bolshezemelskaya Tundra, northeast European Russia)

For the first time an annotated list of mosses of the northernmost «island» relict spruce forest in the northeast European Russia has been compiled. The Spruce forest was isolated from the area of spruce (Picea obovata) presumably 4.5 thousand years ago. Spruce «island» is located in Bolshezemelskaya Tundra, in the middle reaches of the More-Yu River on the territory of the state nature reserve of regional importance (67°49'50"–67°59'67"N, 60°01'47"–60°03'02"E). The total area of spruce communities is about 2.5 km2. The age of the trees is 150–200 years. The annotated list includes 134 species of mosses, of which 17 species are found for the first time for Bolshezemelskaya Tundra. New data on the occurrence of six rare species of mosses included in the Red Data Book of the Arkhangelsk Region (2008) — Aloina brevirostris, Cynodontium strumiferum, Encalypta rhaptocarpa, Meesia uliginosa, Scorpidium cossonii, Tetraplodon mnioides are presented.

Characteristics of the Microarthropod Communities in Postagrogenic and Tundra Soils of the European Northeast of Russia

Microarthropod communities (Oribatida, Mesostigmata, and Collembolans) in postagrogenic and tundra soils of the European Northeast of Russia have been characterized. In the postagrogenic soils, developed in places of former cultivation of perennial and annual crops, Collembolans predominate among microarthropods, while Oribatid mites predominate in the tundra soils. The population density of Mesostigmata has not been subjected to significant changes. In the studied sites, 58 species of Collembolans have been identified, including 33 species in postagrogenic soils and 46 species in tundra soils. A comparison of the species composition of springtails attested to significant differences in the structure of the complexes of dominant species, though no strongly specialized fauna has been found in the postagrogenic soils. No definite relationships between particular soil properties and population densities of different groups of microarthropods have been found, though these groups are definitely differentiated depending on genetic types of studied soils.

Photosynthetic Pigments in Native Plants of the Taiga Zone at the European Northeast Russia

The content and composition of photosynthetic pigments in 160 plant species representing the native flora of the taiga zone in European Northeast Russia were investigated. The amounts and proportions of chlorophylls and carotenoids were shown to depend on plant species, life form, and the attribution of plants to particular geographical and ecological–coenotic groups. On the whole, terrestrial plants of the taiga zone accumulated relatively low amounts of chlorophyll: 2–6 mg/g dry wt. The chlorophyll content in leaves of herbaceous species was 1.5 times larger than in woody plants. The relative content of light-harvesting (antenna) chlorophyll accounted for 55–65% of the total pool of green pigments. The vegetation of the Subpolar Ural mountains, comprising a substantial proportion of arctic and arctic–alpine species, was characterized by the chlorophyll/carotenoid ratio equal to 3. In plants inhabiting the middle Vychegda basin, where boreal species dominated, the chlorophyll/carotenoid ratio was 35% higher than in the Subpolar Ural mountains plants. Despite significant interspecific differences in the content of photosynthetic pigments, the relative content of carotenoids tended to increase in the row: boreal–hypoarctic–arctic and arctic–alpine species. This trend indicates the increasing protective role of carotenoids along with the passage of plants to the north.

Строение древостоев среднетаежных сосняков лишайниковых на европейском северо-востоке России

В статье представлены результаты, характеризующие строение древостоев среднетаежных сосняков лишайниковых на европейском северо-востоке России. Проведен статистический анализрядов распределения деревьев сосны по диаметру и высоте ствола. Установлено, что коэффициентвариации высоты в древостоях сосняков изменяется от 9 до 34 %, а асимметрия близка к нулевомузначению, что свидетельствует о почти нормальном распределении деревьев. Коэффициент вариации диаметра колеблется от 27 до 67 %, что говорит о растянутости распределения особей сосны в насаждениях по этому показателю. Показан вклад деревьев разных ступеней толщины в накопление запасов древесины древостоем. В средневозрастных и приспевающих насаждениях 41–55 % от числа деревьев и 32–41 % от объема древесины приходится на ступень толщины, соответствующую среднему диаметру дерева в древостое, и на две соседние ступени толщины. В спелых и перестойных сосняках эти величины составили 6–48 и 4–46 % соответственно, что отражает наличие нескольких поколений в древостоях на этих стадиях развития. Выявлена статистически достоверная взаимосвязь (положительная и отрицательная) между средним диаметром дерева и числом крупно- и тонкомерных деревьев, тогда как корреляции между средним диаметром дерева и запасом древесины в крупномерных и деревьях средних ступеней толщины не обнаружено. Выведено обобщенное регрессионное уравнение взаимосвязи высоты дерева от его диаметра, которое можно использовать для определения высоты деревьев среднетаежных сосняков лишайниковых на европейском северо-востоке России.
