Adaptation variability and ecological plasticity in the “genotype-environment” system of 22 provenances of Picea abies (Linnaeus) H. Karsten, Picea obovata (von Ledebour) and their introgressive hybrids growing within the Russian Plain were studied. Provenances grow in provenance trials located in the Arkhangelsk, Vologda Regions, and Komi Republic. For assessment of provenances in the “genotype-environment” system, the ranking method was used. Based on a complex ranking index (survival, diameter, height) two local areas of the most adaptive geographic races of P. abies, P. obovata and their hybrid forms were distinguished. In the south-western part of the Russian Plain the best provenances are represented by P. abies and related hybrids from Karelia, Vologda, Leningrad, and Pskov Regions. In the north-eastern part they are represented by P. obovata and its hybrids from the Komi Republic, Arkhangelsk, Sverdlovsk Regions. Provenances of local P. abies and related hybrid forms demonstrate high ecological plasticity on their growing in harsh climatic conditions of the north outside of the species distribution area.

Abstract Phenotypic plasticity of 22 spruce provenances in three test plots located in the European North of Russia was studied. Parent spruce stands are located within the Russian Plain and are represented by Picea abies (L.) Karst., P. obovata (Ledeb.) and two introgressive hybrids. In the test plots located in the middle and southern taiga subzones P. abies provenances are tested northward of its distribution area and P. obovata provenances are tested within the distribution area and nearby its boundaries. phenotypic plasticity of the spruce provenances was assessed. Straight-line regression coefficient based on survival, diameter, and height was calculated. All provenances are divided into two groups: plastic and non-plastic provenances. High plasticity is observed more often for P. abies and hybrids forms with properties of P. abies. Plastic provenances based on three parameters grow in the Leningrad, Pskov, Vologda, Kostroma and Karelia. Area of parent stands growing is quite small-size and lies between 56º30´ – 61º40´ N and 30º30´ – 42º30´ E. Adaptive provenances of P. obovata and its related hybrids forms grow in the North-Eastern part of the Russian Plain that could be consequence of its distribution in Holocene. Picea abies being the more adaptive species would be more responsive to climate changes in terms of survival and growth rate than P. obovata. Therefore, in case of sustainable climate warming in the Northern areas of the Russian Plain, the further propagation and major distribution of P. abies with further competitive replacement of P. obovata can be expected.

Abstract This research presents the variability in the survival and growth for 27 provenances of spruce (Picea abies (L.) Karst. and Picea obovata (Ledeb.)). All the tests were carried out in Russia, Arkhangelsk region, 62º 54’ N, 40º 24’ E, in the northernmost site of the State Geographic Network, established in 1977. For the research on the spruce provenances, standard methods for studying the geographic variation of the main forest-forming species were used. Growth rates of provenances were correlated with their geographical coordinates and climatic characteristics. Data was expressed in standard deviation units to select the best in growth provenances. Despite the significant differences in the location of the original stands (up to 12º N and 37º E), variability in survival, height and diameter is low (coefficient of variation is 12.2–19. 0%). Obtained data indicated that provenances’ growth is correlated on longitude of the location rather than on the latitude. Diameter and average height of provenances significantly depend on annual rainfall. The height of provenance is mostly dependent on the location of the initial habitats and their climatic characteristics. It is also related to the length of the growing season and the air temperature (annual average and in January). Groups of the provenances of the best and the worst growth were distinguished. The group of the best ones on the integral indicator (volume stand) includes provenances of the western origin represented by P. abies and its immediate hybrids – Karelia (3), Vologda (24), Leningrad (5), Pskov (7) and Moscow (29) Regions – and provenances of the eastern one represented by P. obovata – Komi (26) and Perm (38) Region. High plasticity of spruce (P. abies (L.) Karst. × P. obovata (Ledeb.)), growing within the Russian Plain, in sufficiently favourable conditions of middle taiga subzone (Arkhangelsk Region, Russia) was proved.

Abstract The article presents the results of provenance trials carried on the Norway spruce (Picea abies (L.) Karst.), the Siberian spruce (Picea obovata Ledeb.) and hybrid forms of these two species. The trails were laid in 1977-1978 according to wide-scale All-Union program of 1972 year (Prokazin 1972) in the Arkhangelsk, Vologda, Leningrad regions and the Republic of Bashkortostan. The results of the most recent inventory of provenance trials as well as analyses of preservation and growth of spruce progenies with different geographical origin are presented. One of the main factors affecting spruce progeny survival was north-south distance between seed collection locality and test locality. At the time of the study (2010-2012), in the Vologda and Arkhangelsk regions, spruce progeny preservation was higher in the case of mother stands distant to the north. On the contrary, in the Leningrad region and the Republic of Bashkortostan, preservation of northern climatypes’ progenies was lower during the whole period of plantations’ growth. With the change of seed collection locality towards west-east direction, a correlation between progeny preservation and geographical origin factors was non-existent (Vologda, Arkhangelsk regions) or weak (Leningrad region, Republic of Bashkortostan). The most successful growth and the lowest preservation were observed under the conditions of sharp-continental climate, in provenance trials carried out in the Bashkortostan Republic. In the north of Russia, in provenance trials in the Arkhangelsk region there was observed the slowest spruce growth. On the whole, at all the objects under investigation, Norway spruce progenies and hybrid forms with Norway spruce properties showed better growth parameters when compared to those of the Siberian spruce.

AbstractAbundant mammal (45 localities) and plant (52 sections) fossil data collected from the Russian Plain deposits of the Middle Valdai Briansk Interstade indicate a period of noticeable warming. These materials were jointly analyzed. The data were organized in the database software PARADOX and then moved to the GIS program ARC/INFO. Mathematical methods as well as traditional research methods were used for the analysis. The reconstructed biogeographical provinces illustrate the specific environmental and climatic conditions of the Briansk Interstade. Analogues of modern natural zones did not exist at this time on the Russian Plain. The Briansk landscapes reflect the moderate-cool climate of this period, when the majority of northern subarctic plant and mammal species extended their ranges considerably to the south to the Central Russian Plain. At the same time, steppe species penetrated farther north and west. This combination shows that the continuous forest zone was destroyed during the Briansk Inter-stade. Five biogeographical provinces have been reconstructed from the north to the south for the Russian Plain during the Briansk warming on the basis of joint analysis of mammalian and botanical data.

AbstractCladonia subturgida is a Mediterranean species that has been overlooked. Apparently it was restricted to the Iberian Peninsula and Canary Islands. However, during the study of the genus Cladonia in the Mediterranean region, new populations from 44 localities were found in: south France, Sardinia, south Italian peninsula, Crete and continental Greece. Distribution models based on MaxEnt, GLM, GAM and MARS algorithms were used to estimate the potential distribution of C. subturgida. Sicily, Corsica and the north of Africa were regions with suitable climatic conditions for C. subturgida where it has not been reported yet. The climatic variables with greatest relative influence in the C. subturgida distribution were the Precipitation of Warmest Quarter and the Annual Precipitation. Additionally, the ITS rDNA region was used to study the genetic variation of this species across its distribution area. Eleven haplotypes were found, one of them widely distributed through its geographical range. AMOVA analyses indicated lack of geographical structure.


The purpose of this article is to highlight the possibilities of successful grape growing based on the use of agro-climatic resources of the Eastern forest-steppe of Ukraine, in particular, the relevant areas of Kharkiv region. Main material. Attention is drawn to the needs to intensify research and practical activities on the cultivation of grapes in the region. In the agricultural sector of Ukraine interest in cultivating grapes is growing in more in northern areas, than in its traditional distribution area. An urgent task is a more thorough study of agro-climatic conditions, clarifi cation of agro-clima tic zoning of this culture and the development of practical recommendations. This is especially true of the Eastern forest-steppe of Ukraine and its individual areas, including the northern part of Kharkiv region. This industry, judging by the success of farms and individual economies, can be highly profi table throughout the region but with some reservations. Currently, one of the problems of viticulture is to obtain suffi cient yield to supply the population. For this purpose, the author identifi es the features of the natural conditions of the region. Clarifi cation of agro-climatic features of the territory can be considered as a multi-stage task of agro-climatic zoning at diff erent levels. The Eastern forest-steppe region should be considered as part of a large agroecosystem, occupying a signifi cant place in the forest-steppe zone of Ukraine. Of particular interest are the climatic indicators, the assessment of which allows to justify the grape culture management. These indicators are grouped together. The most important of them are temperature, humidity, light conditions and features of the winter period. Distribution of rainfall (fl ow of water) in the phases of grapes development during the active growing season is also important. It is also necessary to pay a???? ention to the use of other indicators. Most of them are closely related to the hydrothermal coeffi cient (HTC) - the simplest and most informative indicator. It should be added that using special agricultural techniques cultivation of certain grape varieties can be possible in the north-east of Ukraine. Conclusions. The study of suitable forest-steppe agrometeorological regions in Kharkiv region for growing grapes in natural conditions continues to be relevant. This difficult task requires a lot of effort and involvement of specialists.

Географические культуры ели, заложенные на территории Любанского лесничества Ленинградской области в 1977 г., являются частью эксперимента, организованного на территории бывшего СССР по программе ВНИИЛМ. На основании выполненного исследования приведены первые результаты оценки устойчивости ели к грибным болезням. Средняя сохранность 40летних культур в группе потомств Picea abies составляет 39, P. оbovata 26. На протяжении всего периода развития культур северные и восточные потомства имеют более низкую сохранность. Снижение сохранности культур обусловлено факторами географического происхождения семян, а также отсутствием рубок ухода. Выявлены очаги некрознораковых заболеваний и гнилей. Высокая распространённость некрознораковых заболеваний (51 62) прослежена в потомствах псковского, костромского, медвежьегорского и сегежского климатипов. Стволовая гниль находится в начальной стадии развития загнившие сучки и плодовые тела возбудителей на растущих деревьях не выявлены. Отмечаются признаки развития опёнка Armillaria mellea s. l., вызывающего корневую и комлевую гниль. Категория состояния по объекту 2,85, с колебаниями от 2,67 2,76 (P. abies и гибридные формы P. abies) до 2,95 3,09 (P. оbovata и её гибридные формы), что свидетельствует об ослаблении или о сильном ослаблении насаждений с нарушением их устойчивости. Низкая категория состояния (3,3 3,4) отмечена в потомствах гибридных форм с признаками P. оbovata кареломедвежьгорского и архангельскоплесецкого происхождений. В группе потомств P. abies прослежена достоверная зависимость категории состояния от географического происхождения семян: с удалением мест заготовок семян на север и восток состояние культур хуже. Среди гибридных форм с признаками P. оbovata лучшим состоянием отличаются восточные потомства. Provenance trials of spruce, established on the territory of the Lyubansky Forest District of the Leningrad Region in 1977, are a part of a vast experiment started on the territory of the former USSR. On the basis of the studies performed, the first results of the assessment of the spruce resistance to fungal pathogens are presented. The average preservation of 40yearold trials in the Picea abies progenies group is 39 and in P. ovovata is 26. During the whole period of cultures development northern and eastern progenies had lower rate of preservation. The decrease in the preservation of provenance trials is due to factors of geographical origin of seeds, as well as the lack of selection thinning. Foci of necrosiscancerous diseases and rots were identified. A high distribution rate of necrosiscancerous diseases (51 62) was traced to the progenies of Pskov, Kostroma, Myedvezhegorsk and Segezha climatypes. Stem rot is in the initial stage of development: rotten knots and fruiting bodies of pathogens on growing trees have not been found. There are signs of the development of honey fungus Armillaria mellea s.l., which causes root and butt rot. The state category of the object is 2.85, with fluctuations from 2.67 2.76 (P. abies and hybrid forms of P. abies) to 2.95 3.09 (P. оbovata and its hybrid forms), which indicates decline, or strong decline of forest stands with loss of their sustainability. The low state category (3.3 3.4) is noted in the progenies of hybrid forms with P. obovata properties of KarelianMyedvezhegorsk and ArkhangelskPlesetsk origins. In the group of progenies P. abies, a significant dependency of the category of state on the geographical origin of seeds was traced: if we go further to the North and East, the state of the trails is getting worse. Among the hybrid forms with the properties of P. оbovata, the eastern progenies have the best state.

Here, we report the data on modern state and protection prospects of plant species Anemone altaica Fisch. ex C.A.Mey., Anemone nemorosa L., Anemone ranunculoides L., Ficaria verna Huds. (Ranunculaceae), Corydalis solida (L.) Clairv. (Papaveraceae) and Gagea samojedorum Grossh. (Liliaceae) in the taiga zone of the Komi Republic. These ephemeroid species require a special research due to their biological features (short periods of vegetation in the spring and subtle presence in communities at later dates) and geographic localization. One of the species, Gagea samojedorum is an endemic of the Urals, other species are presented by populations on the border of their distribution areas. Until recently, studies of early-flowering ephemeroids in the north-east Russia have not been performed. However, such studies become more and more important due to an active industrial development of the North. To assess the prospects for the conservation of rare early-flowering ephemeroids, we carried out work to clarify the number of locations of species on the territory of the Komi Republic, compiled maps of their distribution (See Fig. 1), collected and summarized information about the area, the number and the structure of 44 coenopopulations (See Tables 1 and 2), as well as identified limiting factors. It is shown that at the edge of the distribution area, ephemeroid species often have fragmented habitat range due to ecological and phytocoenotical preferences. They occur sporadically in the river and stream floodplains (sometimes at limestones) where soils are moist and fertile. In the floodplain meadows and forests, ephemeroids can form one-two species ecotopical assemblages. The populations of ephemeroids are linear, often with a high number of individuals. Self-recovering of short-root Anemone altaica, A. nemorosa, A. ranunculoides and root-tuber Ficaria verna is made, mainly, by vegetative reproduction. Tuber species Corydalis solida is propagated only by seeds. The ontogenetic structure of populations indicates a decline in seed and vegetative reproduction rate in these species at the edges of distribution areas (See Fig. 2 and 3). The Ural endemic Gagea samojedorum occurs in herbal habitats and sparse forests in foothill and mountain areas of the Ural Mountains, where it forms abundant populations with the prevalence of young individuals. A high reproduction rate of Gagea samojedorum is due to the variability of vegetative reproduction. In the Komi Republic, the anthropogenic impact on the ephemeroid species is low due to a low level of industrial development and population. Natural abiotic and biotic factors are more significant here and may weaken species positions in plant communities, as well as limit the growth, development and self-recovering of the populations. By now, Anemone altaica, A. nemorosa, A. ranunculoides, Corydalis solida, Ficaria verna and Gagea samojedorum have been included in regional Red Books of plants with the protection category 3 (rare). The main reasons for their inclusion are the edge location, small number, isolation of the local populations and often relic origin. Gagea samojedorum is also an endemic species. The object of the UNESCO World Heritage List “Virgin Komi Forests” and the number of regional reserves are important for the preservation of ephemeroid plants in the North.

Пахотные угодья Республики Коми в основном представлены дерново-подзолистыми почвами с низким естественным плодородием, которые без применения удобрений быстро подвергаются деградационным процессам, что резко снижает их продуктивность. Цель исследований: оценка эффективности долговременного применения органических и минеральных удобрений при выращивании картофеля в кормовом севообороте в условиях Республики Коми. Методической основой выполнения работ были комплексные исследования дерново-подзолистых почв, клубней картофеля на участках многолетнего полевого эксперимента, заложенного на землях Института агробиотехнологий ФИЦ Коми НЦ УрО РАН в соответствии с «Методическими указаниями географической сети опытов с удобрениями». Длительный период исследований (более 40 лет) характеризовался различными климатическими условиями, которые отразились на количестве урожая и качестве клубней картофеля. Было проведено 7 ротаций (14 лет) с выращиванием картофеля. Вносили органические удобрения – торфонавозный компост (ТНК) в дозах 40 и 80 т/га (1 и 2 фон, соответственно) под картофель и минеральные удобрения – NPК в дозах 1/3; 1/2 и 1 для восполнения выноса растениями элементов питания. Установлено положительное влияние комплексного применения органических и минеральных удобрений на урожайность и качество картофеля, а также на плодородие дерново-подзолистой легкосуглинистой среднеокультуренной почвы в кормовом севообороте в почвенно-климатических условиях Республики Коми. В результате применения шестипольного севооборота и комплексного внесения удобрений с 1978 года к 2019 году в почвах снизилась обменная и гидролитическая кислотность; повысилось содержание гумуса на 0,5% (в контроле); на 0,2–0,5% (с тремя дозами минеральных удобрений); на 0,3–1,1% (с ТНК); на 0,2–1,6% (при совместном применении органических и минеральных удобрений). Наибольшие урожаи картофеля получены при совместном применении органических (80 т/га) и минеральных удобрений (1 NPК) и составили 37,1 т/га клубней (8,5 тыс/га кормовых единиц). При таком соотношении удобрений показано высокое качество клубней картофеля: содержание крахмала 15,5%, витамина С – 19,4 мг%, сырого протеина – 14,1%. Количество нитратного азота не превышало ПДК (ПДК 250 мг.с.м.). Экономические расчеты показали, что при внесении ТНК 40 т/га + 1 NPК в дерново-подзолистые почвы с.-х. использования в среднетаежной зоне Республики Коми при выращивании картофеля, условный чистый доход составит 68,4 тыс. р. с 1 га, себестоимость 1 т картофеля – 2,8 тыс. р., рентабельность 188,7%. The arable land of the Republic of Komi is mainly represented by dern-sub-ground soils with low natural fertility, which without the use of fertilizers are quickly subjected to degradation processes, which dramatically reduces their productivity. The aim of the research is to evaluate the efficiency of long-term use of organic and mineral fertilizers in the growing of potatoes in feed crop rotation in the conditions of the Komi Republic. The methodological basis for carrying out the works was comprehensive studies of dern-subhead soils, potato tubers on the sites of a multi-year field experiment laid on the lands of the Institute of Agrobiotechnology of the FRC Komi SC UB RAS in accordance with the «Methodological Instructions of the Geographical Network of Experiments with Fertilizers». A long period of research (more than 40 years) was characterized by different climatic conditions, which affected the number of crops and the quality of potato tubers. There were 7 rotations (14 years) with potato cultivation. Organic fertilizers – peat-avous compost (TNK) in doses of 40 and 80 t/ha (1 and 2 background, respectively) for potatoes and mineral fertilizers – NPK in doses of 1/3; 1/2 and 1 to replenish the carry-out of food elements by plants. The positive effect of the integrated use of organic and mineral fertilizers on the yield and quality of potatoes, as well as on the fertility of soddy-podzolic light loamy medium cultivated soil in fodder crop rotation in the soil and climatic conditions of the Komi Republic, has been established. As a result of the use of six-bed crop rotation and the integrated application of fertilizers, metabolic and hydrolytic acidity decreased in soils from 1978 to 2019; humus content increased by 0.5% (in control); 0.2–0.5% (with three doses of mineral fertilizers); 0.3–1.1% (with TNCs); 0.2–1.6% (with combined use of organic and mineral fertilizers). The largest potato yields were obtained from the combined use of organic (80 t/ha) and mineral fertilizers (1 NPK) and amounted to 37.1 t/ha tubers (8.5 thousand/ha feed units). The largest potato harvests were obtained with the combined use of organic (80 t/ha) and mineral fertilizers (1 NPK) and amounted to 37.1 t/ha of tubers (8.5 thousand/ha of feed units). With this ratio of fertilizers, the high quality of potato tubers was also determined: the starch content was 15.5%, vitamin C – 19.4 mg%, crude protein – 14.1%. The amount of nitrate nitrogen did not exceed the MPC (MPC 250 mg.s.m.). Economic calculations showed that if TNK is added 40 t/ha 1 NPK to the dern-sub-ground soils of agricultural use in the medium-sized zone of the Komi Republic when growing potatoes, the conditional net income will be 68.4 thousand rubles from 1 ha, the cost of 1 t of potatoes – 2.8 thousand rubles, profitability 188.7%.

A growth in the number of deer and an increase in their productivity are closely related to the solution of the complex problem of reproduction and rational use of deer females. Significant damage to reindeer husbandry is caused by the barrenness of northern domestic deer, the level of which has been quite high in recent years. So, in the Republic of Sakha, on 01.01.2020, the number of domesticated reindeer was 152,068, of which female deer and heifers — 71,818, offspring per 100 females — 59, business yield amounted to 52 fawns per 100 females. The causes of infertility are very diverse, as the natural and climatic conditions of the breeding zones have a significant influence on the reproductive function of reindeer. In Yakutia, the main population of northern domestic deer is bred in mountain taiga and tundra natural-climatic zones, so there are about 55 thousand deer in the mountain taiga zone and more than 65 thousand deer in the tundra zone. In this regard, the study of the peculiarities of the postpartum period course in domestic reindeer females, its morphophysiology, and behavioral reactions depending on the natural and climatic conditions of breeding is of great importance.
