Abstract The investigation was carried out to evaluate the influence of glutathione (GSH: levels 0, 0.1, 0.5 1.0, and 2.0 mM) on the callus growth, shoot multiplication and phytochemicals of in vitro shoots of the Date palm cv. Barhee. The optimum concentration of GSH was 1.0 mM. Such concentration improved the callus growth and increased its weight to 312.0 mg, the addition of this substance of the same concentration level showed the highest response rate and the number of shoots per jar (73.34 ± 2.69 and 8.83 ± 0.80 shoots/jar, respectively). Also, the 1.0 GSH application resulted in reducing the percentage of browning to 0.0 compared to the other concentrations. The results of the biochemical analysis revealed that treatments GSH of 0.1, 0.5 and 1.0 mM reduced the total soluble phenols compound (TSPC). These treatments were also more effectively reducing peroxidase (POD) and phenylalanine ammonia-lyase (PAL) activity than the concentrations of 2 mM or 0 (control treatment).
摘要研究了谷胱甘肽(GSH:0、0.1、0.5、1.0和2.0mM)对椰枣试管苗愈伤组织生长、芽增殖和植物化学物质的影响。GSH的最适浓度为1.0mM。该浓度可促进愈伤组织的生长,并使其重量增加到312.0mg,添加相同浓度的GSH可显示出最高的响应率和每罐芽数(分别为73.34±2.69和8.83±0.80芽/罐)。此外,与其他浓度相比,施用1.0的GSH使褐变的百分比降低到0.0。生化分析的结果显示,0.1、0.5和1.0mM的GSH处理降低了总可溶性酚类化合物(TSPC)。这些处理也比2mM或0的浓度(对照处理)更有效地降低过氧化物酶(POD)和苯丙氨酸解氨酶(PAL)活性。

Abstract The aim of the study was to analyze the origin of oak stands within the catchments of the Vorskla’s tributaries and to describe their state. Covering 60,900 ha, pedunculate oak (Quercus robur L.) stands prevail and cover 51.1% of the total forest area of 119,200 ha in the catchment areas of the River Vorskla’s tributaries. The way oak stands are distributed in regards to trophotopes points at favourable conditions for their growth, as 81.7% of the area is a fresh fertile oak forest site type. Forest stands aged 41–80 years (39.8 % of the total area) and 81–120 years (50.4%) are prevailing. Natural oak stands cover almost 66.5% and planted ones grow at 33.5%. Distribution of oak stands in regards to the functional categories of forests shows a significant predominance of the protective forests. They cover 46.6% of the total area. The commercial forests cover 23.0%, the recreational ones make 18.8% and the forests with conservational, academic, historical and cultural purpose cover 11.6 %. Distribution patterns of oak forests in the catchments of the River Vorskla’s tributaries should be considered in the forest management in order to conserve their biodiversity and enhancing the performance of important environmental, protective, recreational and other functions. The article contains results of the study on the natural regeneration of Quercus robur and other wood species under the canopy of oak stands and on felling sites. The further research perspectives are a thorough study of the stand characteristics and the typological structure of forests in terms of certain wood species in the catchments of rivers all over Ukraine. It will help developing principles for the catchment and landscape zonation.
摘要本研究的目的是分析Vorskla支流集水区内橡树林的起源,并描述其状态。Vorskla河支流集水区119200公顷的总森林面积中,以带蒂橡树(Quercus robur L.)为主,面积60900公顷,占51.1%。橡树林在营养方面的分布方式为其生长提供了有利的条件,因为81.7%的面积是新鲜肥沃的橡树林类型。41–80岁(占总面积的39.8%)和81–120岁(50.4%)的林分占主导地位。天然栎林占66.5%,人工栎林占33.5%。从森林功能类别来看,栎林的分布显示出防护林的显著优势。它们占总面积的46.6%。商品林占23.0%,休闲林占18.8%,具有保护、学术、历史和文化目的的森林占11.6%。森林管理中应考虑Vorskla河支流集水区橡树林的分布模式,以保护其生物多样性,提高重要的环境、保护、娱乐和其他功能。本文介绍了在栎林冠下和采伐现场对粗壮栎和其他木材物种自然再生的研究结果。进一步的研究视角是对乌克兰各地河流集水区的林分特征和森林类型结构进行深入研究。它将有助于制定集水区和景观区划的原则。

Abstract We investigated the current health condition (defoliation), state of natural regeneration, and mycoflora and phytopathogen-caused attacks in Scots pine forests (Pinus sylvestris L.) planted in the 1960s in areas affected by wind disturbances in the West Rhodope Mountains in Bulgaria. Some damage types (resin outflow and anthropogenic damage) were present to a low extent in the research plots (S – Selishte and PK – Pobit Kamak). Some were missing completely (damage by deer and other animals, the presence of lignicolous fungi and abiotic damage). The most important results of this study were the following: i) the occurrence of the bark beetle pest Tomicus minor Hartig (Coleoptera, Scolytinae) was recorded on average in 4.6 (S) and 2.3 (PK) of fallen shoots under the tree crown within 1 m diameter around the stem; ii) significant damage to tree crowns due to the loss of assimilation organs in Scots pine trees (28% – S and 39% – PK, respectively) was several times higher than that recorded in Norway spruce (Picea abies L.) (10%); iii) tree species composition resulting from natural regeneration showed 95–100% proportion of Norway spruce despite the predominance of Scots pine in the maternal stand. These observations might provide evidence of unsuitable environmental conditions in the studied localities for pine forests on the southern range of the natural P. sylvestris occurrence. Forest management in similar ecological and climatic conditions should aim at significant diversification of the forest stand structure by utilizing tree species suitable for the given ecosystems.
摘要我们调查了保加利亚西罗多佩山脉受风扰动影响地区20世纪60年代种植的苏格兰松(Pinus sylvestris L.)目前的健康状况(落叶)、自然再生状态以及真菌群和植物病原体引起的攻击。一些损害类型(树脂流出和人为损害)在研究地块中的程度较低(S–Selishte和PK–Pobit Kamak)。一些完全失踪(鹿和其他动物造成的损害、木质素真菌的存在和非生物损害)。本研究最重要的结果如下:i)在树干周围1m直径内树冠下的落叶芽中,平均记录到4.6(S)和2.3(PK)发生了树皮甲虫害虫Tomicus minor Hartig(鞘翅目,Scolytinae);ii)由于苏格兰松树同化器官的损失(分别为28%–S和39%–PK)对树冠的严重损害是挪威云杉(Picea abies L.)(10%)的数倍;iii)自然再生产生的树种组成显示,尽管母林中苏格兰松占主导地位,但挪威云杉的比例为95%至100%。这些观测结果可能为研究地区天然樟子松分布的南部范围内的松林提供了不合适的环境条件的证据。类似生态和气候条件下的森林管理应通过利用适合特定生态系统的树种,实现林分结构的显著多样化。

Change in photosynthetic pigments of Date palm offshoots under abiotic stress factors 非生物胁迫条件下椰枣枝条光合色素的变化

Abstract Increasing world temperatures are bringing about climate changes creating abiotic stress in plants. Date palm offshoot leaves (Khadrawi cv.) were analyzed for chlorophyll Chl a, Chl b, Total Chl, Chl a/b ratio, anthocyanin and carotenoid subject to salinity, drought and temperature stress under field conditions. Results demonstrated that drought and salinity stress accompanied by high temperatures in July and August significantly reduced the Chl a, Chl b, and Total Chl relative to the control. Anthocyanins, carotenoids, hydrogen peroxide, and malondialdehyde were markedly higher in July and August (45 ºC), whereas September showed lower values in these substances. Temperature reduction to 35 °C accompanied by drought or salinity stress, brought about a critical increment in relative water content and a decrease in electrolyte leakage. Although the impact of drought and salinity stress continued, the reduced temperatures in September resulted in a reduction of abscisic acid and proline concentration. Cluster analysis showed the two groups. In this first group, the significant similarity between the treatments is illustrated by the influence of the high temperature of 43–45 ºC. Recovery of photosynthesis following low-temperature, for the most part, determines plant flexibility to water deficiencies and salinity. Thermal stress, associated with salinity or drought stress is more damaging to the photosynthetic pigments than any single factor.
全球气温升高带来的气候变化给植物带来了非生物胁迫。在盐碱、干旱和温度胁迫条件下,对枣树枝叶叶绿素Chl a、Chl b、总Chl、Chl a/b比值、花青素和类胡萝卜素含量进行了分析。结果表明,与对照相比,7、8月干旱、盐胁迫和高温显著降低了Chl a、Chl b和Total Chl。花青素、类胡萝卜素、过氧化氢和丙二醛在7月和8月(45℃)显著升高,而9月这些物质的含量较低。温度降低至35°C,并伴有干旱或盐度胁迫,相对含水量临界增加,电解质泄漏减少。尽管干旱和盐胁迫的影响仍在继续,但9月份气温的降低导致脱落酸和脯氨酸浓度的降低。聚类分析显示两组。在第一组中,43-45ºC高温的影响说明了处理之间的显著相似性。低温后光合作用的恢复,在很大程度上决定了植物对缺水和盐度的适应性。与盐胁迫或干旱胁迫相关的热胁迫对光合色素的损害比任何单一因素都要大。

Abstract Various treatments can be used to break physical dormancy (PY, i.e. water-impermeable seed coat) of legume species, but the effects of these treatments on seedling growth are of great importance in the success of afforestation projects. Our aims were to determine the effects of 20 PY-breaking treatments on (1) germination of Gleditsia caspica (Caspian locust) seeds and (2) seedling growth. Five germination and nine seedling growth and morphological traits were studied. Immersion in concentrated sulfuric acid (98%) for 60 minutes was optimal for all germination traits and for all seedling traits except root length. After seed coat removal or treatment with sulfuric acid (for 45 to 120 minutes), 99–100% of the seeds germinated, but seedling growth traits after 5 months were significantly lower in the former than in the latter treatment. Other treatments (e.g., different periods of exposure to cold water, boiling water, and KNO3) did not significantly increase germination or improve seedling growth. Thus, despite incurring adverse environmental impacts, sulfuric acid treatments have the best potential to break seed dormancy and produce high-quality seedlings (in terms of shoot length, root and shoot mass, root area, leaf number and area and collar diameter) of Caspian locust.
摘要各种处理可以用来打破豆科植物的物理休眠(PY,即不透水的种皮),但这些处理对幼苗生长的影响对造林项目的成功至关重要。我们的目的是确定20个PY破坏处理对(1)皂荚(里海蝗虫)种子发芽和(2)幼苗生长的影响。研究了5个发芽和9个幼苗的生长和形态特征。在浓硫酸(98%)中浸泡60分钟对所有发芽性状和除根长外的所有幼苗性状都是最佳的。在去除种皮或用硫酸处理(45至120分钟)后,99–100%的种子发芽,但5个月后前者的幼苗生长特性显著低于后者。其他处理(例如,暴露于冷水、沸水和KNO3的不同时期)并没有显著提高发芽率或改善幼苗生长。因此,尽管会产生不利的环境影响,但硫酸处理最有可能打破种子休眠,生产出优质的里海蝗虫幼苗(就地上部长度、根和地上部质量、根面积、叶数和面积以及项圈直径而言)。

Abstract Forest growth is commonly used to explore tree vitality and ability to resist to environmental changes or climatic fluctuations. This paper illustrates and examines how regional climatic conditions can be related to the decline of tree growth, which were found to be more distinct in Quercus frainetto Ten. (Hungarian oak) and Fagus sylvatica L. (European beech) and less pronounced in Abies borissi-regis Matt f. (Bulgarian fir) on three long-term intensive monitoring plots (ICP Forests-Level II) in Greece during the period 1996–2009. Relative basal area increment and volume increment were calculated, expressing tree growth in terms of mean relative annual periodic increment. A decline in the growth of basal area and volume was observed after hot and dry periods, where annual temperatures and precipitation were far from the mean of the analyzed period. This observation was statistically confirmed in oak and beech plots regarding summer precipitation only and are in agreement with the findings of previous studies in Europe. The representativeness of the results at a national scale needs further investigation, although our results provide a good basis for further and more intensive monitoring programs to address various forest management scenarios against the background of potential climatic changes in the Mediterranean area.
摘要森林生长量通常用来考察树木的生命力和抵抗环境变化或气候波动的能力。本文说明并研究了区域气候条件如何与树木生长下降有关,这在栎树生长下降中更为明显。1996年至2009年期间,在希腊的三个长期密集监测地块(ICP森林二级)上,匈牙利橡木和欧洲山毛榉(Fagus sylvatica L.)和保加利亚冷杉(Abies borisi -regis Matt f.)的变化不太明显。计算相对基面积增量和体积增量,用平均相对年周期增量表示树木生长。在干热期之后,年平均气温和降水量远低于分析期的平均值,基底面积和体积的增长呈下降趋势。这一观察结果在统计上得到了橡树和山毛榉地块上的证实,仅与夏季降水有关,并且与先前在欧洲进行的研究结果一致。尽管我们的结果为进一步和更密集的监测方案提供了良好的基础,以解决地中海地区潜在气候变化背景下的各种森林管理方案,但结果在全国范围内的代表性需要进一步调查。

Abstract The Alpine musk deer (Moschus chrysogaster) is classified as an “Endangered” species by the IUCN Red list category. We studied anthropogenic pressure on the musk deer population in the Khaptad National Park, Nepal. The questionnaire survey was applied from October to November 2018. Out of 111 respondents, 77% reported that the primary objective for poacher kills to the musk deer was musk pod, followed by skin (15%) and meat (8%).

Abstract Research into small mammals and their ectoparasites was carried out in the Belianske Tatras during 2010–14, evaluating flea communities found on small mammals on the basis of species richness, abundance and level of infestation. Flea infestation of host species occurred mostly in C. glareolus with the highest infestation rates recorded in S. alpinus, the earlier mentioned C. glareolus, N. anomalus and N. fodiens. Based on their prevalence in all the examined hosts, the most frequent flea communities found were M. turbidus, C. agyrtes, A. penicilliger and P. soricis. In addition, flea prevalence in all the captured host species was evaluated. The most frequent flea communities were M. turbidus, P. soricis and D. dasycnema (8 host species); C. agyrtes and H. orientalis (7); A. penicilliger and P. bidentata (4); C. uncinatus, P. sylvatica and R. integela (3); and M. rectangulatus, N. fasciatus and C. bisoctodentatus (2), while A. nuperus and A. arvicolae were recorded in only one host species.
摘要2010-2014年间,在Belianske Tatras对小型哺乳动物及其体外寄生虫进行了研究,根据物种丰富度、丰度和侵扰程度评估了小型哺乳动物身上发现的跳蚤群落。寄主物种的跳蚤侵扰主要发生在甘叶C.glareolus,其中高山S.alpinus、前面提到的甘叶C.aleolus、N.anomalus和N.fodiens的侵扰率最高。根据它们在所有受检宿主中的流行率,发现最常见的跳蚤群落是M.turbidus、C.agyrtes、A.penicilliger和P.soricis。此外,还评估了所有捕获宿主物种的跳蚤流行率。最常见的跳蚤群落是M.turbidus、P.soricis和D.dasycnema(8个寄主物种);C.agyrtes和H.orientalis(7);A.penicilliger和P.bidentata(4);C.uncinatus、P.sylvatica和R.integela(3);以及M.rectangulatus、N.fasciatus和C.bisoctodentatus(2),而A.nuperus和A.arvicolae仅记录在一个寄主物种中。

Abstract The dhole (Cuon alpinus) is one of the least frequent studied endangered canid species and many aspects of ecological knowledge about this species are lacking. The objectives of this study were to investigate the spatial movement of dholes, prey abundance, prey selection, and prey overlaps with other large carnivorous species in the Huai Kha Khaeng Wildlife Sanctuary, Thailand, during November, 2017 and October, 2018. Two adult female dholes were captured and fitted with GPS collars. Twenty camera trap sets were systematically used to survey the area. Scat collection was conducted along forest roads and trails. The home range sizes and activity radii of the two dholes were 3,151.63 ha. and 1,442.84 m, and 33.39 ha and 331.56 m, respectively. The sambar deer (Rusa unicolor) was the most abundant prey species (30.93%). However, dhole fecal analysis showed that the monitored dholes preferred red muntjac (Muntiacus muntjak) (57.1%). There was a high degree of prey overlap between dholes and leopards (98%), indicating very high prey competition. The dholes in this study represent movement patterns in richly abundant prey habitats, but with the presence of other predators that can affect prey selection and movement patterns of the dhole in the area.
摘要:全孔犬(Cuon alpinus)是濒危犬科动物中研究频次最少的物种之一,对其生态认识的许多方面都很缺乏。研究了2017年11月至2018年10月泰国怀卡亨野生动物保护区洞洞的空间运动、猎物丰度、猎物选择以及与其他大型食肉动物的猎物重叠情况。捕获了两只成年母洞,并安装了GPS项圈。系统地使用了20套摄像机来调查该地区。沿着森林道路和小径收集粪便。两个钻孔的钻孔范围大小和活动半径为3151.63 ha。1,442.84 m, 33.39 ha, 331.56 m。鹿(Rusa unicolor)是最丰富的猎物,占30.93%。然而,粪便分析显示,被监测的豚鼠偏好红麂(Muntiacus muntjak)(57.1%)。洞与豹之间的猎物重叠程度很高(98%),表明猎物竞争非常激烈。本研究中的洞代表了丰富的猎物栖息地的运动模式,但其他捕食者的存在会影响该地区洞的猎物选择和运动模式。

Abstract Despite their extensive distribution globally, recent reports indicate leopards are declining, especially in Southeast Asia. To support conservation efforts we analyzed the behavioral interactions between leopards (Panthera pardus), their prey, and tigers to determine if leopards fine-tune their activity to maximize contact with four prey species (sambar; wild boar; barking deer; banteng) and avoid tigers and if prey alter their temporal activity in response to variation in their relative abundance ratio with leopards. A lower density of sambar in the northern part of our study area and a lower density of wild boar and a higher density of tigers in the southern part allowed us to examine fine-grained differences in the behavior of leopards and their prey. We used camera trap data to investigate spatial and temporal overlap. Differences in tiger relative abundance did not appear to impact the temporal activity of leopards. Leopards had similar cathemeral activity at all sites with highest activity at dawn and dusk. This behavior appears to be a compromise to provide access to diurnal wild boar and barking deer and nocturnal sambar and banteng. Sambar showed higher temporal avoidance of leopards in the north where its RAI was lowest; in contrast, wild boar had the highest temporal avoidance in the south where its density was lowest. This is the first study in Southeast Asia to quantify spatial and temporal interactions between the leopard, its primary ungulate prey, and the tiger. It provides new insights for conserving this declining subspecies.
尽管豹子在全球广泛分布,但最近的报告表明,豹子正在减少,尤其是在东南亚。为了支持保护工作,我们分析了豹子(Panthera pardus)、它们的猎物和老虎之间的行为相互作用,以确定豹子是否会微调它们的活动,以最大限度地与四种猎物(桑巴;野猪;叫鹿;它们会避开老虎,如果猎物会根据它们与豹子的相对丰度比的变化而改变它们的时间活动。在我们的研究区域北部,桑巴尔的密度较低,而在南部,野猪的密度较低,老虎的密度较高,这使我们能够研究豹子及其猎物行为上的细微差异。我们使用相机陷阱数据来调查空间和时间重叠。老虎相对丰度的差异似乎不会影响豹子的时间活动。豹子在所有地点都有相似的大教堂活动,在黎明和黄昏活动最高。这种行为似乎是一种妥协,以提供白天的野猪和吠鹿和夜间的桑巴和班腾。Sambar在北部表现出较高的时间躲避性,其RAI最低;而野猪在密度最低的南方有最高的时间回避。这是东南亚第一个量化豹和老虎之间时空相互作用的研究,豹是它的主要猎物。它为保护这个日益衰落的亚种提供了新的见解。
