Abstract Like other ecosystems, burnt peatlands will run into natural regeneration, characterized by pioneer plants’ presence as a succession process guard. However, annual burnt peatlands can complicate vegetation growth, including the pioneer's presence. Besides that, it is unknown what kind of grow pioneers are, so the research aims to find out the pioneer plants’ diversity on burnt peatlands is essential. The reasonably extensive distribution of peat ecosystems and high fire potential in Sumatra is Tanjung Jabung Regency of Jambi Province selected to study. The locations of plant species inventory are Orang Kayo Hitam Forest Park (burnt five times), village forest (HD) Sinar Wajo, and HD Koto Kandis Dendang (each burnt once) using the Nested Quadrat and Line Transect of vegetation survey method. Vegetation analysis showed that 22 pioneers were found in HD Sinar Wajo and 27 species in HD Koto Kandis Dendang. Some are identified as ferns (Pteridophyta), breed with spores, and pioneer plants reproduce by seeds (Spermatophyta). In Orang Kayo Hitam Forest Park found 26 species consisting of plants, trees, shrubs, and lianas. Among the three locations, we found the same type of pioneer. It is implied that patterns and regeneration processes can help each other in the same landscape.
与其他生态系统一样,燃烧后的泥炭地也会经历自然更新,其特征是先锋植物的存在作为演替过程的守卫。然而,每年燃烧的泥炭地会使植被生长复杂化,包括开拓者的存在。此外,目前尚不清楚先锋植物是什么样的,因此研究的目的是找出烧焦泥炭地先锋植物的多样性是至关重要的。选取占碑省丹戎贾邦县作为研究对象,研究了苏门答腊岛泥炭生态系统分布较广且具有较高的火灾潜力。植物物种清查地点为Orang Kayo Hitam森林公园(烧毁5次)、村庄森林(HD) Sinar Wajo和HD Koto Kandis Dendang(各烧毁1次)。植被分析显示,在HD Sinar Wajo和HD Koto Kandis Dendang分别发现了22种和27种先锋植物。有些被鉴定为蕨类植物(蕨类植物),通过孢子繁殖,而先锋植物通过种子繁殖(精子植物)。在Orang Kayo Hitam森林公园发现了26种植物,树木,灌木和藤本植物。在这三个地点中,我们发现了相同类型的拓荒者。这意味着在同一景观中,格局和再生过程可以相互帮助。

Abstract The purpose of the research was to assess the species composition and biodiversity indices for xylophagous beetles collected by window traps in the parts of Gomilshanski lisy National Nature Park with different management regimes and anthropogenic load. Four window traps were placed in each of the five groups of sample plots: clear felling, selective felling, stationary recreation, regulated recreation and protected zone. The data were analysed using the statistical software package PAST, particularly, the Menhinick index (DMn) and dominance index (D) were evaluated and classical clustering (unweighted pair-group average [UPGMA]) was performed. A total of 42 species of xylophages (9903 individuals) were collected from Curculionidae (Scolytinae and Cossoninae), Cerambycidae, Histeridae, Bostrichidae, Buprestidae and Lymexilidae. The highest species richness was in the plots of clear and selective felling (25 and 22 species, respectively) and the lowest was in the protected zone (16 species), regulated recreation (19 species) and stationary recreation (22 species). The Menhinick index (DMn) was the lowest in the protected zone (0.27), increased in the zone of regulated recreation (0.43) and stationary recreation (0.45) and was maximal in the plots of selective and clear felling (0.69 and 0.77, respectively). The number of individuals was maximal in the protected zone and minimal at the plots of selective and clear felling. All sites were dominated by Xyleborinus saxesenii (Ratzeburg, 1837) (66–85% individuals) and Anisandrus dispar (Fabricius, 1792) (8.5–20.7% individuals). Minimal dominance (0.49) was found in the plot of clear felling. Cluster analysis showed similarity of the xylophage complex in the plots of clear and selective felling, as well as in the zone of stationary and regulated recreation, which differed from the protected zone.
摘要本研究旨在评价不同管理制度和人为负荷下格米尔山斯基国家自然公园部分地区窗捕法采食木食甲虫的种类组成和生物多样性指数。在5组样地中分别设置了4个窗捕器,分别为:明确采伐、选择性采伐、固定游憩、管制游憩和保护区。使用统计软件包PAST对数据进行分析,特别是评估Menhinick指数(DMn)和优势度指数(D),并进行经典聚类(未加权对组平均[UPGMA])。共采集到木噬细胞42种(9903只),分别来自蛭蝇科、天牛科、蛭蝇科、白蝇科和灰蝇科。物种丰富度最高的是明确采伐地和选择性采伐地(25种和22种),最低的是保护区(16种)、管制游憩地(19种)和静止游憩地(22种)。Menhinick指数(DMn)在保护区最低(0.27),在调控游憩区(0.43)和静止游憩区(0.45)增加,在选择性采伐和明净采伐区最大(分别为0.69和0.77)。在保护区的个体数最多,在选择性采伐和明确采伐地的个体数最少。所有生境以Xyleborinus saxesenii (Ratzeburg, 1837)(66-85%)和Anisandrus dispar (Fabricius, 1792)(8.5-20.7%)为优势种。清林样地的优势度最小(0.49)。聚类分析结果表明,清伐区和选择性采伐区、休养区和调控游憩区木噬体复合体具有相似性,与保护区不同。

Abstract The purpose of the research is to study the current state, features of growth and formation of Scots pine (Pinus sylvestris L.) stands in Eastern Polissia of Ukraine. The structure of pine stands by origin, age, the density of stocking, site indices, forest types and health condition was analysed. Features of the formation of stands were studied at the permanent sample plots. Visual assessment of health condition, as well as signs of pest and disease damage of trees, other defects and external signs that caused stem defects was carried out. The age structure of pine stands was not optimal: there was an excess of mature stands and a lack of young stands. The health condition of mixed pine stands was relatively better than that of pure pine stands. Mixed pine stands were characterised by high biological resistance and accumulated significant wood stock under regular sylvicultural maintenance. The dynamics of forestry and evaluation indicators of reference pine stands were evaluated and comparison of their growth with stocked pine stands was performed.
摘要本研究旨在研究乌克兰东波兰地区苏格兰松(Pinus sylvestris L.)林分的现状、生长和形成特征。从产地、林龄、放养密度、立地指数、林型和健康状况等方面对松林结构进行了分析。研究了永久样地林分形成的特征。对树木的健康状况、病虫害损害迹象、其他缺陷和导致茎部缺陷的外部迹象进行了目视评估。松林年龄结构不理想,成熟林过多,幼林不足。混交松林的健康状况相对好于纯松林。混交松林具有较高的生物抗性,在定期造林维护下积累了大量的木材。对参考林分的林业动态和评价指标进行了评价,并将参考林分的生长情况与已有林分进行了比较。

Abstract Productive European beech stands (Fagus sylvatica L.) involving Scots pine (Pinus sylvestris L.) are formed in Ukrainian Roztochie. Considering value and limited distribution of beech stands involving pine in tree species composition, it is necessary to work out and implement measures for their natural restoration in connection with the climate change and the efficient use of raw materials and non-wood products. Main forestry and management indices of beech stands that include pine in tree species composition were analysed. Forestry activities that are currently carried out in middle-aged and maturing stands significantly reduce their relative completeness and growing stocks, as determined by comparing growth particularities of productive beech stands from different sources.
生产欧洲山毛榉林(Fagus sylvatica L.)涉及苏格兰松(Pinus sylvestris L.)在乌克兰Roztochie形成。考虑到涉及松木的山毛榉林分在树种组成中的价值和分布的有限性,有必要制定和实施与气候变化、原料和非木制品的有效利用相结合的自然恢复措施。分析了树种组成中含松山毛榉林分的主要林业管理指标。目前在中年和成熟林分进行的林业活动大大降低了它们的相对完整性和生长量,这是通过比较不同来源的生产性山毛榉林分的生长特性而确定的。

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.
摘要本文研究了机动车交通对公园生态系统和蒲公英网各项指标的影响。,以及它们对乌克兰最大的大都市,即基辅的城市环境的生物指示的适用性。我们在14个暴露于不同程度航空污染负荷的公园生态系统中进行了调查:普什查-沃迪茨亚(公园)及其郊区的低污染水平,沿7条中等交通道路的平均污染水平,沿8条高速公路的高污染水平。采用花粉指示法、积分法和统计法确定空气污染物影响的最敏感指标。目的是利用生物指示和GIS技术评估车辆排放对大都市公园生态系统状况的影响。揭示了空气污染在时间和空间上对细胞、生物、群体和生态系统水平上的绿色基础设施的影响。在航空污染的影响下,出现了树木退化、干枯、树冠落叶和公园生态系统综合指标恶化的现象。利用QGIS(免费开源地理信息系统,版本3.12.3“București”,2020年5月15日),我们绘制了空气污染物扩散地图。空气污染和公园破坏最严重的地区集中在城市中心建筑密集的地区和交通繁忙的道路附近。植物毒物的平均日最大允许浓度(MAC)超过1.5 MACa.d。这取决于地形和盛行风的方向。特大城市生态状态连续7年退化19.3%。

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.
摘要本研究的目的是在北方针叶林典型生长条件下,评价昼夜气象参数(气温、露点、相对湿度、风速和降水)对松木径向生长的影响。这项研究是在阿尔汉格尔斯克地区(俄罗斯)北部进行的。从7个最具代表性的地点共选出63个岩心。气象参数来自WMR 918h数字气象站(德国Huger GmbH),该气象站直接位于研究区域并以监测模式运行。该分析使用了2008-2015年期间的气象数据。蓝莓品种与6、7月昼夜气温的相关系数为0.72 ~ 0.77。所有林分与风速均存在正相关(0.77 ~ 0.88)和负相关(- 0.7 ~ - 0.99),但各样地间存在个体相关性。与8、9月湿度呈负相关(0.64 ~ 0.87),与5、8月降水呈负相关(- 0.63 ~ - 0.75)。一般来说,蓝莓松、红莓松和沼泽松对气象因子的变化有相似的反应,其中最重要的是空气的温度状态和风速。

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.
在Bolshoy Solovetsky岛的中部,在相同的生长条件下,于1988年创建了两个地块:第一个地块由扭曲的松树(Pinus contorta Loud)组成。第二种是苏格兰松(Pinus sylvestris L.)。本研究的目的是建立在Bolshoy Solovetsky岛条件下扭曲松的形态参数及其与本地种P. sylvestris L.的比较,并确定扭曲松的特征,确定进一步引进该物种的可能性和必要性。决定保留扭曲松和苏格兰松文化。选择会计树(分别为62棵和31棵),对其形态计量指标进行测量。木材样本(岩心)是用年龄钻来测量径向生长的。采用MBS-9显微镜和Lintab装置测量径向增量。为了测量高度的增加,我们砍倒了6棵中等大小的模型树。根据税收指标,这两种类型略有不同,而且这种差异通常是不可靠的。扭松的平均高度明显高于苏格兰松。树皮的厚度各不相同;在18岁时,松皮厚度平均为1.35±0.038 mm,苏格兰松为1.86±0.095 mm,即本土松皮厚度增加38%。典型的扭曲松在22%的研究树木中注意到大量的病理。扭曲松的特点是同化装置的发展更强:一级分支的数量,在轮中的分支的数量,针的寿命。年轮半径(年轮宽度)在14 ~ 15年呈增加趋势,然后随着年龄的增长,扭曲松的年轮半径逐渐减小,而苏格兰松的年轮半径一直保持在较高水平。苏格兰松年轮晚带宽度为12%,扭松年轮晚带宽度为14%;但是在年轻的时候,扭曲的松树的后期木材非常小。扭松的平均高度增长量小于苏格兰松。树干体积对直径的依赖性在两种中几乎相同。

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.
摘要本研究的主要目的是鉴定具有历史价值的古栎(Quercus robur L.)和天麻(Tilia cordata L.)的独特基因库,以表征其遗传多样性,并利用EST-SSR(表达序列标记-单序列重复)标记确定其多态性,从而筛选出最有价值的标本。形态学描述、分子遗传分析和统计学分析均被用于研究。利用EST-SSR标记和形态特征,确定了不同栎、椴老树间的遗传距离。利用聚合酶链反应(PCR)获得了预期大小的等位基因。结果表明,7个SSR标记可获得4 ~ 8个等位基因。根据位点多态性指数(多态性信息含量[PIC])的计算值,多态性最多的是标记SSRQrZAG 65;PIC为0.84。标记SSRQrZAG 11的PIC值最低;PIC为0.69。所有研究标记均检测到遗传内多态性。在所研究的椴树样品中,鉴定出2 ~ 5个等位基因。结果表明,标记Ts920 - 0.72的PIC值最高。多态性最小的是标记Ts927 (PIC为0.28),这不仅是由于等位基因数量少,而且它们在样本中的分布不均匀。结果表明,6个标记中有4个标记存在遗传内多态性,所有样本均存在遗传内多态性,可根据等位基因的分布来评估其遗传多样性。

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.
摘要本研究旨在分析不同森林生长条件下,维伊斯科维沟壑区坡地和沟壑区抗侵蚀人工林pallasiana D. Don松针非结构性碳水化合物代谢的特点。该峡谷位于第聂伯罗彼得罗夫斯克地区,属于峡谷森林的南部地理变体。所研究的植物生长在三个人工人工林的实验地点:在塔林(森林生长条件-中氧,新鲜,CL2),在南暴露的斜坡中部(中氧,有点干燥,或半干旱,CL1)和在这个斜坡的上部(干燥,干旱,CL0-1)。研究了5月至10月期间葡萄糖、果糖、还原糖、蔗糖和淀粉的变化。在水热参数最不利的月份,渗透活性物质(葡萄糖、蔗糖)的浓度增加,特别是在中氧和亲氧森林生长条件下的植物中。7月和10月是果糖含量变化的两个高峰,葡萄糖浓度呈稳定上升趋势,10月达到最高值。在研究期间,坡顶和坡顶中部干旱条件下的松针中果糖含量远低于坡顶新鲜条件下的松针中果糖含量。淀粉含量的动态曲线从5月的最大值逐渐减小到8月的第一个最小值。随后,这种多糖的浓度有所增加,但没有达到以前的值。第二次最低限额是在10月份。在所有森林生长条件下,都能观察到植物针叶中淀粉含量的这种变化。多糖含量的下降与葡萄糖和蔗糖含量的增加是一致的,特别是在8月份。与正常水分条件相比,在不利的水热条件下,白杨针叶中可溶性渗透保护糖(葡萄糖、蔗糖)的浓度显著增加,这表明植物具有适应中氧和嗜干环境的能力。

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.
波斯尼亚和黑塞哥维那的甜栗树林在森林总基金中代表性不足,其面积今天正在下降。本研究旨在确定波斯尼亚克拉伊纳(波黑西北部)种群板栗叶、果实和叶片形态性状的相关关系,以便开展选育活动。测定了果实、叶片和茎节的11个性状,评价了7个性状,计算了6个性状。用Pearson相关系数r计算各性状间的相关系数。在果实性状和偶对性状比较时,针尖长度与大部分果实性状的相关均具有统计学显著性。对果数和针尖长度性状与叶片宽度和叶柄长度的相关系数均有统计学意义。相关性状对甜栗子的进一步选育具有重要意义。研究结果表明,甜板栗遗传物质具有丰富的遗传多样性来源,可用于在波黑地区选育新品种和保护本土基因库。
