Abstract Urbanization is a form of pervasive human-induced disturbance. We tested the effectiveness of Abundance/Biomass Comparisons (ABC) as an approach in detecting stress due to landscape urbanization in large small mammal assemblages obtained from pellets of Barn Owl (Tyto alba; Strigiformes). We compared three assemblages sampled in not urbanized contexts (agro-mosaic landscapes) with three assemblages preyed in highly urbanized contexts. In all assemblages, the role of strictly synanthropic species (in our case: rodents) emerged since almost all of total biomass was assigned to these species: indeed, everywhere (both in agro-mosaic and urbanized sites) species of low trophic level (i.e. omnivorous/herbivorous rodents) significantly prevail in biomass when compared to insectivorous species (i.e. shrews, Soricomorpha) linked to less anthropized habitats. This biomass dominance in rodent species is highlighted by the data on evenness, showing lower values in biomass when compared to abundance. This pattern did not match with the classic assumption expressed by the ABC model (i.e., species with higher biomass are typical of undisturbed assemblage) and could be wrongly interpreted. Our study evidenced as ABC approach is a not reliable tool to detect the effect of urbanization as landscape disturbance acting on small mammal assemblages. Therefore we suggest that the ABC assumptions are not universal but limited only to assemblages where high body mass species coincide to species of a higher trophic level.

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.

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。

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.

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.

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.

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%). The major part of the killing tools represented traps; however, 23% respondents stated that poachers also use snares, 20% respondents reported guns, and 18% persons interviewed had no idea regarding the tool the poachers use to kill the musk deer. There was a significant difference between the male and female respondents regarding their opinion on musk deer conservation; male respondents exhibited more positive attitudes towards musk deer conservation than female respondents (Chi-squared 8.21; P < 0.05). People based conservation awareness programs and alternative income generating sources must be employed for long term musk deer conservation in the Nepal Himalayas.

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。

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.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":"46 1","pages":"127 - 136"},"PeriodicalIF":1.3,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47390945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 This paper tested the hypothesis that the placement of trees in the floodplain ecosystem leads to multiscale spatial structuring and plays an important role in formation of the spatial patterns of the soil macrofauna. The research polygon was laid in an Eastern European poplar-willow forest in the floodplain of the River Dnipro. The litter macrofauna was manually collected from the soil samples. The distances of the sampling locations from the nearest individual of each tree species were applied to obtain a measure of the overstorey spatial structure. The pure effect of tree structured space on the soil animal community was presented by the broad-scale and meso-scale components. The soil animal community demonstrated patterns varying in tree structured space. The tree induced spatial heterogeneity was revealed to effect on the vertical stratification of the soil animal community. The complex nature of the soil animal community variability depending on the distance from trees was depended on the interaction of tree species in their effects on soil animals. The importance of the spatial structures that interact with soil, plants and tree factors in shaping soil macrofauna communities was shown.
