  • The results of the introduction of twisted pine () in Bolshoy Solovetsky
           Island

    • Abstract: In the central part of the Bolshoy Solovetsky Island, in the same type of growing conditions, two plots were created in 1988: the first consisted of twisted pine (Pinus contorta Loud. var. latifolia S. Wats) crops and the second one was of Scots pine (Pinus sylvestris L.). The aim of the study was to establish the morphological parameters of the twisted pine and its growth in the conditions of the Bolshoy Solovetsky Island in comparison with the native species P. sylvestris L. Also, we aimed to identify the features of P. contorta var. latifolia and determine the possibility and necessity of further introduction of the species. The preservation of the twisted pine and scots pine cultures was determined. Accounting trees were selected (62 and 31 trees, respectively), in which morphometric indicators were measured. Wood samples (cores) were taken from them with an age drill to measure radial growth. The radial increment was measured using the MBS-9 microscope and the Lintab device. To measure the increase in height, six medium-sized model trees were cut down. According to the taxation indicators, the two types differed slightly and the differences were most often unreliable. The average height of the twisted pine trees was significantly higher compared to that of Scots pine. The thickness of the bark varied; on average, at the age of 18, it was 1.35 ± 0.038 mm for twisted pine and 1.86 ± 0.095 for Scots pine, that is, the native pine bark was 38% thicker. Typical for twisted pine were a significant number of pathologies noted in 22% of the studied trees.Twisted pine was distinguished by a stronger development of the assimilation apparatus: the number of branches of the first order, the number of branches in the whorl, the life span of needles. An increase in radius (the width of the annual ring) was observed at 14–15 years, and then with age, the value decreased in twisted pine and remained at a consistently high level in Scots pine. The width of the late zone of the annual ring was 12% in Scots pine and 14% in twisted pine; but at a young age, the late wood in twisted pine was very small. The increase in height of the twisted pine was on average less than that of Scots pine. The dependence of the trunk volume on the diameter was almost identical in both species.

  • Genetic characterisation of centuries-old oak and linden trees using SSR
           markers

    • Abstract: The main goal of this study was to identify the unique gene pool of old and historically valuable Quercus robur L. and Tilia cordata L. to be able to characterise their genetic diversity in order to determine the polymorphism by expressed sequence tag-single sequence repeat (EST-SSR) markers and identify the most valuable specimens.Morphological description, molecular genetic analysis, and statistical analysis were used in studies. The genetic distances between old-value trees of different Quercus L. and Tilia L. were determined based on EST-SSR markers and morphological characteristics.Using polymerase chain reaction (PCR), alleles of the expected size were obtained. It was determined that four to eight alleles were obtained by seven SSR markers in the studied Q. robur L. samples. According to the calculated value of the locus polymorphism index (polymorphism information content [PIC]), the most polymorphic was the marker SSRQrZAG 65; the PIC was 0.84. The lowest value of PIC was observed in the marker SSRQrZAG 11; the PIC was 0.69. Intragenetic polymorphism was detected for all studied markers. Among the studied samples of linden, two to five alleles were identified. It was found that the highest value of PIC was obtained for the marker Ts920 – 0.72. The least polymorphic was the marker Ts927 (PIC was 0.28), which is not only due to the small number of alleles, but also their uneven distribution in the sample. Intragenetic polymorphism was detected in four of the six markers analysed for T. cordata L.In this study, polymorphism was detected in all studied samples of Q. robur L. and T. cordata L., which allows to assess their genetic diversity based on the distribution of alleles.

  • Bioindication of megalopolis park ecosystems under aerotechnogenic loading

    • Abstract: This study focuses on the influence of motor transport on various indicators of park ecosystems and Taraxacum officinale Web., as well as on their applicability to the bioindication of the urban environments in the largest megalopolis of Ukraine, namely, Kyiv. Our investigations were carried out in 14 park ecosystems exposed to different levels of aerotechnogenic loading: low pollution level in Pushcha-Vodytsya (park) and outskirts, average pollution level alongseven roads with medium traffic and high pollution level along eight highways. Pollen indication, integration and statistical methods were used to identify the most sensitive indicators of the impact of air pollutants. The aim is to assess the impact of vehicle emissions on the state of park ecosystems in the metropolis using bioindication and GIS technologies. The effects of air pollution on green infrastructure at the level of cells, organisms, groups and ecosystems in time and space are revealed. Under the influence of aerotechnogenic pollution, there is a deterioration of trees, their drying, defoliation of crowns and deterioration of integral indicators of park ecosystems. Using QGIS (Free open source geographic information system, version 3.12.3 „București”, May 15, 2020), we have created maps for the spread of air pollutants. The highest levels of air pollution and damage to parks were concentrated in the central part of the city with dense buildings and near heavy traffic roads. The average daily maximum allowable concentration (MAC) of phytotoxicants exceeded 1.5 MACa.d. and depended on the terrain and directions of the prevailing winds. We registered degradation of the megalopolis ecological state by 19.3% for 7 years.

  • Correlations among morphological traits of sweet chestnut ( Miller) from
           Bosnia and Herzegovina

    • Abstract: Sweet chestnut forests in Bosnia and Herzegovina are underrepresented in the total forest fund, and their area is declining today. The research aims to determine the correlation relations of morphological traits of chestnut leaves, fruit and cupule in the population of Bosnian Krajina (northwestern Bosnia and Herzegovina) to undertake selection and breeding activities. Eleven traits of fruits, leaves and cupules were measured, seven assessed and six calculated. A mutual correlation for the researched traits was calculated using the Pearson correlation coefficient r. When the fruit traits and cupule traits were compared, the needle length showed a statistically significant correlation with most of the fruit traits. The traits of the number of fruits in the cupule and needle length had a statistically significant correlation coefficient with leaf blade width and leaf petiole length. The correlated traits can be distinguished as important for further selection and breeding of sweet chestnuts. The research results indicate that the genetic material of sweet chestnut is a rich source of genetic diversity and can be used in selection to obtain new varieties and cultivars in Bosnia and Herzegovina and for the protection of the indigenous gene pool.

  • Dynamics of non-structural carbohydrates in D. Don needles under different
           forest growth conditions of ravine anti-erosion plantations

    • Abstract: The research was aimed at analysing the peculiarities of non-structural carbohydrate metabolism in the needles of Pinus pallasiana D. Don in anti-erosion plantations on the slope and in the thalweg of the Viyskovyi ravine under different forest growth conditions. The ravine is located in the Dnipropetrovsk region and belongs to the southern geographical variant of ravine forests. The studied plants grew at three experimental sites of man-made plantation: in the thalweg (forest growth conditions – mesophilic, fresh, CL2), in the middle part of the slope of the southern exposure (mesoxerophilic, somewhat dry, or semi-arid, CL1) and on the upper part of this slope (xerophilic, arid, CL0–1). Changes in glucose, fructose, reducing sugars, sucrose and starch during the period from May to October were studied.The concentration of osmotically active substances (glucose, sucrose) increases in the months with the most unfavourable hydrothermal parameters, especially in plants of mesoxerophilic and xerophilic forest growth conditions. The dynamics of fructose content revealed two maxima (July and October), when the concentration of glucose tends to increase steadily, with the highest values found in October. During the study period, the level of fructose in the needles under the arid conditions of the upper and middle parts of the slope was much lower than under the fresh conditions of the thalweg. The dynamics curve of the starch content tends to decrease from the maximum values in May to the first minimum in August. It is followed by some increase in the concentration of this polysaccharide that does not reach the previous values. The second minimum is registered in October. Such changes in the level of starch in the needles of plants are observed under all forest growth conditions. The decrease in polysaccharide content is consistent with the increase in glucose and sucrose, especially in August. A more significant increase in the concentration of soluble osmoprotective sugars (glucose, sucrose) in P. pallasiana needles under unfavourable hydrothermal conditions compared to normal moisture conditions indicates the ability of plants to adapt to mesoxerophilic and xerophilic conditions.

  • Effect of meteorological factors on the radial growth of pine latewood in
           northern taiga

    • Abstract: The purpose of this study is to evaluate the influence of day and night meteorological parameters (air temperatures and dew points, relative humidity, wind speed and precipitation) on the radial growth of pine latewood in northern taiga, in typical conditions of its growth. The study was conducted in the north of the Arkhangelsk region (Russia). A total of 63 cores were selected from seven most representative sites. Meteorological parameters were obtained from the WMR 918 H digital weather station (Huger GmbH, Germany), located directly on the study area and operating in monitoring mode. The analysis used meteorological data for the period 2008–2015. Correlation with night and day air temperature in June and July (0.72–0.77) was revealed in blueberry type. In all the stands studied, a reliable correlation with wind speed was established, direct (0.77–0.88) and inverse (−0.7 to −0.99), but each sample plot had an individual dependence. A reliable correlation with the humidity of August and September (0.64–0.87) and an inverse correlation with precipitation in May and August (−0.63 to −0.75) were established. In general, pine in blueberry, cowberry and pine on swamp types have a similar reaction to the variability of meteorological factors, the most important of which is the temperature regime of air and wind speed.

  • Can standardisation of the unit costs of wood extraction be applied in the
           financial system of the State Forests'

    • Abstract: The paper presents a method for grouping forest districts that are characterised by similar natural and forest conditions and the results of standardisation of wood extraction costs for forest districts and regional directorates of the State Forests. The adopted standard costs referred to the costs which determine the reasonable level of costs necessary to perform a specific management task in the given natural, forest and economic conditions of forest districts. Forest districts were grouped based on the forest habitat types and the land diversity index (Wtri), which were determined with statistical methods to be the factors that shape wood extraction costs. In order to determine the standard unit costs of wood extraction, source materials for the year 2017 have been used, which had been obtained from the State Forests Information System for all forest districts in the country. The method of standardising wood extraction unit costs on the basis of forest district groups with similar natural and forest conditions was reduced in 2017 to the designation of eight uniform forest district groups in terms of forest habitat type structure and Wtri index. Standard unit costs of wood extraction, determined on the basis of the methodology presented in the paper, should be used in the State Forests’ financial system.

  • The damage caused by wind in middle-aged Scots pine stands on permanent
           thinning experimental plots

    • Abstract: In July 2002, the very strong hurricane appeared in northern Poland, which caused destruction of forest cover of area more than 10,000 ha. The permanent thinning research plot in a 53-year-old pine stand located in Myszyniec forest district (150 km north of Warsaw) was lying on the edge of damaged area. The following treatments were tested on this plot: 1) control plot (without thinning); 2) schematic cut in 20-year-old stand, selective thinning to 40 years, then thinning from below; 3) schematic cut in 20-year-old stand, then selective thinning; 4) selective thinning in young stand (20–40 years), then thinning from below and 5) selective thinning all the time.A significant part of this plot was completely destroyed and in the other part of the plot, some trees survived. A small part of the plot resisted the wind attack. An analysis of the amount of destroyed trees (measured by basal area) showed no differences between particular silvicultural treatments. The level of damage differed between particular parts of the plot.Another plot located in Ostrów Mazowiecka forest district (100 km NE of Warsaw) with the same thinning treatments was touched by heavy wind in July 2011 when the stand was 62 years old. Unlike the hurricane of 2002, this storm did not destroy the experimental plot which was located outside the zone of heaviest calamity. Therefore, damage on this plot had point and group character. Although on particular measurement units, share of broken or fallen trees did not exceed 10% of total basal area, it can be observed that the lowest level of damage was noticed on plots with selective thinning in young age and thinning from below in older stand.

  • Expected harmfulness of gnawing phyllophagous insects in urban stands of
           Kharkiv city

    • Abstract: Urban stands are becoming increasingly important in improving the environmental health and liveability of cities. However, they weaken as a result of technogenic air pollution and become vulnerable to pests, particularly to non-native forest insects. The aim of this research was to assess potential harmfulness (bionomically determined harmfulness [BDH]), environmentally determined harmfulness (EDH) and generally expected harmfulness (GEH) of the gnawing phyllophagous lepidopterous insects in the green stands of Kharkiv (Ukraine). All supplementary parameters were assessed by analysis of publications and the own experience of authors. BDH was evaluated as a product of the duration of larvae nutrition (p1) and an index of larvae nutrition (p2). An index of larvae nutrition (p2) was considered being proportional to their imago wingspan. EDH was evaluated as a product of the value of damaged tree species (p3), location of plant damage (p4), the period of loss decorative effect (p5) and the prevalence of certain insect species in the stands (p6). GEH was estimated as a product of BDH, EDH and the ability of insect species to the outbreaks (p7).A modified approach for evaluation BDH, EDH and GEH was suggested and implemented, considering phyllophagous leaf miner insects and phyllophagous insects with open lifestyle in the deciduous stands of streets, parks, and Forest Park of Kharkiv city. EDH of insects with an open lifestyle depends on their size and prevalence in the stand. EDH and GEH of all revealed insects with an open lifestyle increase from streets to Forest Park. Among the insects with an open lifestyle, Lymantriidae and Notodontidae had the highest BDH due to the large size and long feeding period of larvae. Among the insects with hidden lifestyle, Cameraria ohridella had the highest BDH due to the highest prevalence and the large duration of feeding period with its several generations.

  • Successive processes at quarry waste dumps of various ages

    • Abstract: This work is dedicated to the study of the succession processes in quarries of different ages in the territory of the Russian Federation and neighbouring countries, namely, Kazakhstan and Ukraine. In selected soil samples from the areas studied, certain physical and chemical properties, the quantitative composition of microbial communities and the diversity of floral species from the quarries were studied. The pH values for the Kuzbass area were found to decrease to 4.8, and in the area of the younger quarries – Inguletsky and Sokolovsky – higher pH values were recorded. The basal soil respiration rate of the Kuzbass quarry was approximately 0.2 mg CO2/g/h. The CO2 carbonate content ranged from 0.05% to 0.6%. The microbial biomass in Kuzbass soil was from 0.87 to 5.10 μg C/g soil, while its quantity in other quarries was 6 times lower, which is associated with the relatively young age of these sites. The study of the diversity of floral species in the Kuznetsk coalfield identified 120 species of upper plants belonging to 34 families. Among them, cereals, legumes and mosses, lichens and algae were predominant. In the territory of Inguletsky and Sokolovsky quarries, the diversity of plant species was much poorer. In this regard, further research will focus on increasing the rate of succession and maintaining ecosystem stability by increasing the share of microorganisms. Also, the study of the possibility to accelerate the restoration of younger flora in the discharges of age careers at the expense of the mycorrhizal communities formation is of high relevance.

  • s. str. in crimea – differentiation and history inferred from genetic
           and morphological markers

    • Abstract: Juniperus excelsa s. str. (Greek juniper) in Crimea is a relic species on the limits of its range, and represents the Mediterranean flora in the Sub-Mediterranean part of the peninsula. Its origin and history in this area remains unresolved. We aimed to analyze phylogeny and potential demographic expansion of the juniper in the Crimea as well as to study its morphological differentiation. We analyzed plant material from 59 trees inhabiting eight populations. Genetic variation assessments were based on the four non-coding chloroplast DNA (cpDNA) fragments and the nuclear internal transcribed spacer region ITS1-5,8S-ITS2 (ITS). To examine the morphological differentiation, eight measured/counted traits of cones, seeds, and shoots were chosen and eight ratios were calculated. Morphological parameters were compared using ANOVA, Student’s t test, discrimination analysis and Kruskal-Wallis and U Mann-Whitney tests. Two cpDNA fragments were polymorphic and, in total, 10 cpDNA haplotypes were found. Haplotype diversity (Hd) ranged from 0.0 to 0.9. Based on both cpDNA and ITS sequences variation, phylogenetic analyses revealed a close relationship of the Crimean junipers to the individuals from other parts of the species range. In general, our molecular results confirmed the low level of genetic differentiation of J. excelsa individuals inhabiting different parts of the species range, likely resulting from a common ancestry. Only slight morphological differences were found between populations with different geographic location or habitat. The analyzes showed the distinctness of the populations from the southern part of the coast. Some unique morphological and molecular features of southern coastal populations imply that they are remnants of Late Pleistocene abundant forests. We suggest that the recent fragmentation of the Juniperus populations in the Crimean Peninsula could have arisen during the Atlantic period of the Holocene.

  • The local populations of the fungus Fr. as drivers of its biodiversity

    • Abstract: Changes that occur on the local level can explain the processes on the population level and, at the same time, are the driving force of species adaptation. This manuscript reports data about genetic diversities of the fungus Schizophyllum commune on the level of a local population. Objects of the study were dicarious cultures of S. commune collected from 38 basidiocarps grown on the territory of Holosiivskyi National Nature Park, Lysa Hora Regional Landscape Park and Feofaniya forest parcel (Ukraine). Results showed similarity of genetic variability of S. commune in different local populations. The heterozygote deficiency of some loci that was discovered might have resulted from new forms of allozymes that have not become widespread or due to small population sizes. The degree of differentiation of genes between local studied populations was moderate due to the high flow of genes. The absence of spatial structuration of genotypes is established, and the Mantel test showed a lack of interconnection between the genetic component and the geographical coordinates of the samples. It has been suggested that wind direction and terrain are the factors that influence the genetic structure of local populations.

  • Accumulation of heavy metals in soil and litter of roadside plantations in
           Western Polissia of Ukraine

    • Abstract: The article presents the results of a study on the influence of roadside forest belts of different species composition on the accumulation of heavy metals in soil and litter along roads of international and national importance in the conditions of Western Polissia of Ukraine. Mobile forms of Cd, Cu, Pb and Zn in soil and forest litter samples were determined in ammonium acetate extract buffer by atomic absorption spectrometry. The analysis of the content of heavy metals, their comparison with the maximum allowable concentrations depending on the composition of plantations and the category of the highway have been done. It is confirmed that roadside forest belts perform important functions in the accumulation of heavy metals in soil and forest litter. It is confirmed that roadside forest belts perform important functions in the accumulation of heavy metals in soil and forest litter. Among all the pollutants studied, the concentration of cadmium was the lowest and that of zinc the highest (especially in forest litter). Lead and copper in this indicator occupied an intermediate position. Despite the different species composition of plantations, the coefficient of concentration of heavy metals in the soil did not exceed the maximum allowable concentrations and was on average in the range of 0.10–0.20 of these indicators. The greatest effect of delaying the migration of heavy metals was observed in forest litter. Therefore, in order to effectively use the biological barrier along the roads, it is necessary to create linear protective belts of deciduous species with Acer platanoides, Betula pendula, Carpinus betulus and Tilia cordata, which give a rich annual litterfall.

  • Air temperature as a determinant of the forest line in the Tatras

    • Abstract: The forest line has been widely studied by a number of scientists representing various research disciplines. Changes in its position are an indicator of climate change. However, despite numerous studies, it is not always known what has the greatest influence on the position of the forest line. In the Tatras, which are Alpine moun-tains, the position of the forest line in places not disturbed by human activity or slope processes mainly depends on the annual mean air temperature and the number of days with negative temperature and its value in the warm season. The most unfavourable thermal conditions are found at the bottoms of concave landforms, just above the forest line. This thermal barrier effectively limits the upward movement of the forest line, even if the average annual temperature increases. Small concave landforms may have a higher vertical temperature gradient and lower air temperature values at their bottoms than larger and higher-lying forms.

  • Current state and productivity of age-old experimental plantations of
           prof. V.D. Ogievsky in the northeastern part of Ukraine

    • Abstract: This research is aimed at determining the health condition and productivity of Scots pine (Pinus sylvestris L.) stands created during 1906–1908 on the initiative of Prof. V. D. Ogievsky. The scheme of silvicultural experiments included: determining the influence of different widths and directions of clear felling on the natural regeneration, testing of pine plantations of pure and mixed composition and the choice of methods for their creation. In terms of health condition, 103–105-year-old artificial pine stands are weakened and their health condition is slightly worse compared to the aged pines of natural origin. The productivity of age-old linden-pine plantations is higher than of pure pine plantations, and the stock of stem wood in plantations created by seed sowing and marketability is higher compared to the plantations created by planting seedlings.

  • Slope aspect and altitude effect on selected soil organic matter
           characteristics in Beskid Mountains forest soils

    • Abstract: In the era of dynamic climate change, it is important to have knowledge on the interactions between climatic factors and processes occurring in the soil environment. The present study aimed to determine how slope aspect and altitude above sea level influence carbon and nitrogen accumulation and dehydrogenases activity of forest soils. The study was conducted in the Beskid Żywiecki in the south-facing part of Poland. Soils of the same texture, with similar vegetation species composition, in different altitude variants (600, 800, 1000 and 1200 m above sea level) and different north-facing and south-facing slope aspect were selected for the study. For each height and slope aspect variant, samples were collected from the surface horizons of soils for further analyses. The basic chemical properties and dehydrogenases activity of the soil samples were determined. Carbon and nitrogen stocks in the surface horizons of the soils were calculated. The analyses confirmed the influence of location conditions on the carbon and nitrogen stocks in mountain forest soils. The stock of carbon and nitrogen increased with the height up to 1000 m a.s.l. In the soils at the highest altitude, the reserve of carbon and nitrogen decreased regardless of the slope aspect variant. There were no statistically significant differences in carbon and nitrogen stocks between slope aspect variant. The highest dehydrogenases activity was associated with the organic horizons of the soils at the lowest altitude in height gradient. In our study, higher dehydrogenases activity was observed in the north-facing slope soils, and this finding can be explained by more stable thermal conditions.

  • The proposal of a new provisional border of range of the acidophilous oak
           forest Hartm. 1934 Scam. et Pass. 1959 in central Poland

    • Abstract: The range of acidophilous oak forest from Quercetea robori-petraeae Br-Bl. et Tx. ex Oberd. 1957 in Central Europe depends largely on the syntaxonomical concept used and is still provisional. The most continental association from this class occurring in Poland is Calamagrostio arundinaceae-Quercetum petraeae Hartm. 1934 Scam. et Pass. 1959. It is present in western and central Poland, but its eastern boundary is not well known. The aims of the study were to survey and document new patches of Calamagrostio-Quercetum in central Poland, to check the internal variation of the association and to summary the known distribution of it in lowlands of central-western and central Poland. 23 phytosociological relevés were made within new stands together with soil sampling. New relevé data was subjected to the numerical Wards classification together with acidophilous oak forests datasets from western Poland and oak-pine forests ones from eastern part of the Country. The new dataset was similar to Calamagrostio-Quercetum. Three subassociations were distinguished. Soil parameters and oak site index did not differ from acidophilous oak forest stands from other parts of Poland. The provisional range of Calamagrostio-Quercetum in central Poland was proposed to be moved by circa 60–90 km to the north-east (approximately as far as the Vistula river line) in order to include south-western part of Mazowsze.

  • Using FORDRY model to forecast transformation of Norway spruce ( (L.)
           Karst.) stands in Nadsyansky Regional Landscape Park (Ukrainian
           Carpathians)

    • Abstract: The aim of this study was to simulate transformation of species composition, biomass and number of treesin spruce stands depending on a possible combination of cutting and planting scenarios as well as climate changes. The FORDRY computer model was used to predict the dynamics of Norway spruce (Piceaabies (L.) Karst.) stands in Nadsyansky Regional Landscape Park in the Ukrainian Carpathians. Potential changes in species composition, biomass and number of trees were forecasted for the next 50 years. Four scenarios, first – warm-dry, second – cutting dead spruce trees, third – cutting all trees andfourth – planting, were compared to the control one. The analysis revealed a rapid decrease of stand biomass in the first decade as a result of spruce decline. The model predicts an increase in beech biomass before the 50th year of simulation in all scenarios. In the planting scenario, the biomass of beech increased up to 199.9 ± 6.9 t·ha-1 in the 50th year. Correlation analysis showed weak autocorrelations of spruce and negative cross-correlations of spruce with the total stand in control and other scenarios. The output of performed simulations is supported with field and literature data. Results of this study can be applied in the long-term planning of the management and conservation activities in this region. The application of FORDRY model was found useful for analysing the potential scenarios of spruce stand transformation in Nadsyansky Regional Landscape Park.

  • Planktonic communities in a small post-peat reservoir (Ustka Forest
           District, Poland)

    • Abstract: The aim of this study was to evaluate the present state of a small (area of 0.2 ha), shallow (mean depth of 2 m) and approximately 30-year-old post-peat reservoir located in Bruskowskie Bagno, a Baltic raised mire in northern Poland. The study was conducted during all seasons of the year (August 2019–July 2020). The reservoir was characterised by a yellow to brown water colour, low pH (5.4) and quite low conductivity (40.4 μS cm-1), which are the main features of dystrophic water bodies. Similar to natural, dystrophic lakes and ponds, the phytoplankton was mainly composed of mixotrophic species like Dinobryon sp. and Gonyostomum semen. The only numerous non-flagellate group within the phytoplankton was desmids, which indicated that the water was influenced by the mire. The reservoir was characterised by a high abundance of ciliates (annual mean of 55.6 cells ml-1) and a very high abundance of rotifers (annual mean of 3.72 ind. ml-1). Among ciliates, the most important were prostomatids, accounting for 53% of the mean annual ciliate abundance. The results of our study indicate that artificial, approximately 30-year-old, post-peat reservoir resembled a natural dystrophic water body.

  • Genetic diversity of in Sweden and conservation implications for
           protection of relict Polish populations

    • Abstract: The natural range of the dwarf birch (Betula nana L.) includes the boreal, subarctic and arctic regions of Europe, Asia and North America, where it is relatively common. In Poland, it is a relict species occurring in fragmented populations. Using the random amplification of polymorphic DNA (RAPD) technique, we investigated the genetic diversity of the four Swedish populations representing a part of the continuous range of dwarf birch. With the knowledge of the level of genetic diversity of a population from a continuous distribution, we can assess the genetic status of polish populations and answer the question if habitat fragmentation and a decrease in population size lead to a loss in genetic diversity. Knowledge of genetic diversity is important for species conservation, especially to predict their ability to respond to environmental pressures. We found that the populations Abisko, Malbo, Gällivare and Storlien, which are located at the edge of the natural range of B. nana and occupy different habitats, are genetically diverse to varying degrees. The northern populations from Abisko and Gällivare showed a lower level of genetic polymorphism than the population from Malbo, the southernmost site of dwarf birch in Sweden. The data presented indicate higher genetic diversity existed within populations, whereas genetic differentiation between populations was lower. The high level of genetic differentiation within B. nana populations that were analysed in the present study may be explained by a limited capacity for dispersal among populations via both pollen and seeds.We found that the level of genetic diversity in one of the Polish populations of B. nana is comparable to that in areas in Scandinavia where populations are large and continuous. Based on these studies, we conclude that the “Linje” population has sufficient genetic resources.
