In polar regions, apart from tundra and glaciers, geothermally active areas with elevated temperatures are important elements of ecosystems. One such geothermally active region characterized by mosaic ecosystems and vast areas covered by recent lava fields is Iceland. The aim of our study was to explore the diversity of invertebrates inhabiting geothermally active lava fields in the Krafla area (Iceland). Eight bryophyte samples were collected from a warm surface, mainly from the steaming areas. We have found Nematoda, Rotifera, Tardigrada and Oribatida in the samples. Habitat analysis demonstrated there to be 12 bryophyte species (five liverworts and seven mosses). The diversity of bryophytes in a single sample ranged from one to six species. The most common bryophyte was Racomitrium lanuginosum (Hedw.) Brid. Four species of tardigrades were found, including one that was new. Pilatobius islandicus sp. nov. is described herein by morphological, morphometric and molecular approaches (COI, 28S rRNA, 18S rRNA). Oribatida mites were identified as two species (Malaconothrus monodactylus (Michael, 1888) and Camisia foveolata Hammer, 1955). The average density of invertebrates was 13.1 ind./g with a maximum of 40.8 ind./g calculated per dry material. The tardigrades found in our study belonged to herbivores, microbivores and omnivores, whereas the mites belonged to saprophages, which indicates complex trophic networks in geothermally active lava fields.
在极地地区,除冻土带和冰川外,气温升高的地热活动区是生态系统的重要组成部分。冰岛就是这样一个地热活跃的地区,其特征是马赛克生态系统和大片新近被熔岩覆盖的地区。本研究的目的是探索冰岛克拉夫拉地区地热活动熔岩区的无脊椎动物多样性。在温暖地表采集了8份苔藓植物样本,主要来自蒸区。我们在样本中发现了线虫、轮虫、缓步虫和甲虫。生境分析表明,该区有苔藓植物12种(苔类5种,苔藓类7种)。单样苔藓植物的多样性在1 ~ 6种之间。最常见的苔藓植物是蓝齿藓(Racomitrium lanuginosum)。Brid。他们发现了四种缓步动物,其中一种是新发现的。本文通过形态学、形态计量学和分子方法(COI, 28S rRNA, 18S rRNA)对岛彼拉多ius islandicus sp. 11进行了描述。甲螨鉴定为Malaconothrus monodactylus (Michael, 1888)和Camisia foveolata Hammer(1955)两种。无脊椎动物平均密度为13.1 ind./g,最大密度为40.8 ind./g。本研究发现的缓步动物属于食草动物、微生物动物和杂食动物,而螨虫属于腐食动物,这表明在地热活跃的熔岩场中存在复杂的营养网络。

Deglaciation rate on southern and western Spitsbergen in the conditions of Arctic amplification 北极放大条件下斯匹次卑尔根岛南部和西部的消冰速率

This paper reports on a morphometric analysis of land-terminating glaciers on southern and western Spitsbergen in the years 1936–2014. An attempt was made to estimate the deglaciation rate and the scale of its acceleration in the 21st century in the conditions of Arctic amplification. Satellite scenes and topographic map sheets were used for the study and were analyzed by means of remote sensing and GIS methods. The study covered 2000–2014 years and concluded that surface recession accelerated on average by a factor of 2.75 compared to the 1936–2000 period, while linear recession was 2.2 times faster. The greatest increase in the deglaciation rate can be observed in the case of glaciers faced to N and W sectors. The deglaciation process is the most advanced in the central part of the island, where small, compact mountain glaciers predominate. In recent years, a slowdown in the deglaciation processes in these glaciers was observed. The studies demonstrate that the deglaciation rate was mainly influenced by the basin relief determining the glacier geometry. The resultant fractal nature of the ice cover makes it highly vulnerable to the disintegration of complex glacial systems into smaller ones due to glacier thinning and the separation of outlets. The acceleration of the deglaciation rate in turn is modified by the climate factor, especially the impact of warming air masses from the N and W sectors where seas are becoming increasingly ice-free and, consequently, have an increasing heat capacity.
本文报道了1936年至2014年斯匹次卑尔根半岛南部和西部陆地末端冰川的形态计量学分析。在北极放大条件下,对21世纪的冰川消融速率及其加速规模进行了估算。利用卫星场景和地形图进行研究,并通过遥感和GIS方法进行分析。该研究涵盖了2000年至2014年,得出的结论是,与1936年至2000年期间相比,地表衰退的平均速度加快了2.75倍,而线性衰退的速度加快了2.2倍。在面向北、西两扇区的冰川中,消冰速率的增加幅度最大。消冰作用在岛中部最为严重,那里主要是小而致密的山地冰川。近年来,观测到这些冰川的消冰过程有所减缓。研究表明,消冰速率主要受盆地起伏决定冰川几何形状的影响。由于冰川变薄和出水口分离,冰盖的分形特性使其极易受到复杂冰川系统分解成较小冰川系统的影响。冰川消融速度的加速反过来又受到气候因素的影响,特别是来自北半球和西半球的变暖气团的影响,这些地区的海洋正变得越来越无冰,因此热容量也在增加。

Geomorphological research based on geomorphological mapping seeks to identify the origins and age of forms as well as to describe the process that created or transformed a particular form. One of the most important aspects of this study is the morphometry and morphology of the landscape. This also applies to the submarine areas, and issues related to marine geomorphometry. Bathymetric data used in this study were obtained from the measurements of the Norwegian Hydrographic Service and measurements conducted by the authors. Its main goal was: to determine the bathymetry of the Recherchefjorden (Bellsund, Svalbard), establish morphometric parameters for the analysis of the morphology of the bottom. The boundaries of zones, related to the specific character of bottom geomorphology linked with geological structure, tectonics and, in particular, the impact of glacial system, was delineated. The sets of landforms (areas) were distinguished based on the morphometric analysis resulting from the determined parameters: slopes, its aspects, curvatures and Bathymetric Position Index. Basically, this areas are concentrated in two zones: the main Recherchefjorden and its surroundings. The delimitation also takes into account the origins and location of theme in relation to the glacial systems. On this basis, moraine areas were distinguished. They are linked with the Holocene advances of two glaciers, Renardbeen and Recherchebreen, mainly during the Little Ice Age. They constitute boundary zones between areas with different morphometric parameters: outer fjord and inner fjord. Moreover, taking into account geology and terrestrial geomorphology it was possible to describe paraglacial processes in this area.
基于地貌学测绘的地貌学研究试图确定形态的起源和年龄,以及描述创造或转化特定形态的过程。本研究最重要的方面之一是景观的形态测定学和形态学。这也适用于海底区域,以及与海洋地貌学有关的问题。本研究中使用的水深数据来自挪威水文测量局的测量和作者进行的测量。其主要目标是:确定Recherchefjorden (Svalbard的Bellsund)的水深测量,建立分析底部形态的形态测量参数。根据与地质构造、构造、特别是冰川系统的影响有关的海底地貌的具体特征,划定了带的边界。根据确定的参数(坡度、坡面、曲率和水深位置指数)进行形态计量学分析,区分地貌(区域)。基本上,这些区域集中在两个区域:主要的Recherchefjorden和它的周围。这种划分还考虑了主题的起源和位置与冰川系统的关系。在此基础上,划分了冰碛区。它们与Renardbeen和Recherchebreen两个冰川的全新世进展有关,主要是在小冰期。它们构成了具有不同形态参数的区域:外峡湾和内峡湾之间的边界地带。此外,考虑到地质和陆地地貌,有可能描述该地区的副冰川过程。

Abstract: Humification plays an important role in stabilization of organic matter in soils of the cryolithic zone. In this context, the degree of organic matter stabilization has been assessed, using instrumental methods, for permafrost peat soils of the eastern European Arctic, based on selected plots from within the Komi Republic (Russian Federation). Humic substances (HSs) isolated from the mire permafrost peats of the forest-tundra subzone of the European Arctic have been characterized in terms of molecular composition. This was accomplished using elemental and amino acid fragments (AAFs) composition. Solid-state 13C nuclear magnetic resonance (13C NMR) spectroscopy was utilized to identify the structure of HSs. Changes in the molar x(H) : x(C) ratio, ratio of aromatic to paraffin fragments and ratio of hydroxy AAFs to heterocyclic AAFs along the peat profiles have been revealed. They are due to the activation of cryogenic processes in the upper part of the seasonally thawing layer, the natural selection of condensed humic molecules, the botanical composition and degree of degradation of peat, which reflect the climatic features of the area in the Holocene. Humic acids and fulvic acids of the peat soils showed the prevalence of compounds with a low degree of condensation and a low portion of aromatic fragments. The aromaticity degree showed the trend to increase within the depth. Changes of quantitative and qualitative parameters of specific organic compounds occur at the permafrost boundary of peatlands, which can serve as an indicator of recent climate changes in environments from the high latitudes. The presented data can be useful in the evaluation of soil organic matter stabilization degree in the active layer and below the permafrost table.
摘要腐殖化作用在冻石器带土壤有机质稳定中起着重要作用。在这方面,利用仪器方法,根据科米共和国(俄罗斯联邦)境内选定的地块,评估了东欧北极永久冻土区泥炭土的有机质稳定程度。从欧洲北极森林-苔原亚带的沼泽冻土泥炭中分离出的腐殖质(HSs)在分子组成方面具有特征。这是完成使用元素和氨基酸片段(AAFs)组成。利用固态13C核磁共振(13C NMR)光谱对hs的结构进行了鉴定。揭示了泥炭分子x(H): x(C)比、芳烃与石蜡碎片之比以及羟基与杂环AAFs之比的变化。季节解冻层上部低温过程的激活、凝聚腐殖质分子的自然选择、泥炭的植物组成和降解程度反映了该地区全新世的气候特征。泥炭土腐殖酸和黄腐酸中存在低凝结度和低芳香碎片含量的化合物。芳香度在深度内呈增加趋势。泥炭地冻土带边界特定有机化合物的定量和定性参数发生变化,可作为高纬度地区近期气候变化的指标。所得数据可用于评价活动层及多年冻土层以下土壤有机质的稳定程度。

Usnea aurantiaco-atra is the dominant flora around King George Island, Antarctica, whose specimens exhibited various phenotypes, even for those with the same ITS sequences in both mycobiont and photobiont. A comprehensive analysis of morphological traits of U. aurantiaco-atra including the reproductive structures, growth forms and ornamentation, cross section of the branches, and the substratum was carried out. Four arbitrary groups were identified based on their reproductive characters, but these groups cannot be distinguished from molecular phylogenetic trees based on fungal or algal ITS sequences. Further, the complicated morphological diversity of the thalli with the same ITS haplotypes in both mycobiont and photobiont suggest that some other factors in addition to the symbionts could influence the morphology of lichens. This implies that lichen is indeed a complex-mini-ecosystem rather than a dual symbiotic association of fungus and alga. Also, a lichenous fungi Phacopsis sp. was identified based on its anatomical characters and ITS sequence, which was also responsible for the black burls-like structures on U. aurantiaco-atra.
Usnea aurantiaco-atra是南极洲乔治王岛(King George Island)的优势区系,其标本表现出不同的表型,即使在真菌和光生物中ITS序列相同的标本也表现出不同的表型。对金银花的生殖结构、生长形态和纹饰、枝条截面、基质等形态特征进行了综合分析。根据其生殖特征鉴定出4个任意类群,但这些类群无法与基于真菌或藻类ITS序列的分子系统发育树区分开。此外,具有相同ITS单倍型的菌体在菌体和光体中具有复杂的形态多样性,这表明除共生体外,还有其他因素可能影响地衣的形态。这意味着地衣实际上是一个复杂的微型生态系统,而不是真菌和藻类的双重共生关系。此外,根据其解剖学特征和its序列鉴定出一种地衣真菌Phacopsis sp.,该地衣真菌也是造成U. aurantiaco-atra黑色瘤状结构的原因。

: In the southern Spitsbergen area, thermal and mineral waters are primarily associated with subpermafrost deep circulation, being mixed with shallow circulation and glacial waters. Four thermal springs, located in the region of Stormbukta (Sørkappland), were studied and analyzed. In the thermal waters, the main cation is sodium, while the main anions are chloride and bicarbonate. The temperatures of the mineral and thermal waters range from 3.4 to 15.1°C. The pH values are between 7.43 and 8.41. The total dissolved solids (TDS) content of the geothermal waters is in the range of 346–4031 mg/l and the Olsok thermal spring has the highest TDS values. Based on the variation in physicochemical characteristics, two thermal water types were distinguished in the study area. The first type is associated with thermal waters originating from deep circulation waters. The second type is associated with the thermal and mineral waters originating from the mixture of subpermfrost hot brines with glacial waters.
在斯匹次卑尔根南部地区,热水和矿泉水主要与次永久冻土层深层环流有关,与浅层环流和冰川水混合。对位于Stormbukta (Sørkappland)地区的4个温泉进行了研究和分析。在热水中,主要的阳离子是钠,而主要的阴离子是氯化物和碳酸氢盐。矿泉水和热水的温度范围为3.4至15.1°C。pH值在7.43 ~ 8.41之间。地热水的总溶解固形物(TDS)含量在346 ~ 4031 mg/l之间,其中Olsok温泉的TDS最高。根据其物理化学特征的变化,将研究区划分为两种热水类型。第一种类型与源自深层循环水的热水有关。第二种类型与源自亚冻土层热盐水与冰川水混合的热水和矿泉水有关。

Antarctica is perceived as one of the most pristine environments on Earth, though increasing human activities and global climate change raise concerns about preserving the continent’s environmental quality. Limited in distribution, soils are particularly vulnerable to disturbances and pollution, yet lack of baseline studies limits our abilities to recognize and monitor adverse effects of environmental change. To improve the understanding of natural geochemical variability of soils, a survey was conducted in the fellfield environments of Edmonson Point (Victoria Land). Soil samples were analyzed for six major (Fe, Ca, Mg, Na, K and Ti) and 24 trace elements (As, Ba, Be, Bi, Cd, Co, Cr, Cs, Cu, Ga, Li, Mn, Mo, Ni, Pb, Rb, Sn, Sr, Tl, U, V, Y, Zn and Zr). Relationships among element concentrations in the samples and local bedrock were analyzed to identify their origin and similarities in geochemical cycles. Element concentrations in the soils were highly variable but generally within the lowest values reported elsewhere in Antarctica. Though values of Cd, Mn, Ni and Zn were relatively high, they are consistent with those in the local soil-forming rocks indicating an origin from natural sources rather than anthropogenic contamination. Chemical composition of soils vs. rocks pointed to alkali basalts as the lithogenic source of the soil matrix, but also indicated considerable alteration of elemental composition in the soil. Considering local environmental settings, the soil elemental content was likely affected by marinederived inputs and very active hydrological processes which enhanced leaching and removal of mobilized elements. Both of these processes may be of particular importance Jerzy Smykla et al. 20 within the context of global climate change as the predicted increases in temperature, water availability and length of the summer season would favor mineral weathering and increase geochemical mobility of elements.
南极洲被认为是地球上最原始的环境之一,尽管越来越多的人类活动和全球气候变化引起了人们对保护该大陆环境质量的担忧。土壤分布有限,特别容易受到干扰和污染,但缺乏基线研究限制了我们认识和监测环境变化不利影响的能力。为了提高对土壤自然地球化学变异性的认识,对维多利亚地埃德蒙森角(Edmonson Point)的农田环境进行了调查。分析了6种主要元素(Fe、Ca、Mg、Na、K和Ti)和24种微量元素(As、Ba、Be、Bi、Cd、Co、Cr、Cs、Cu、Ga、Li、Mn、Mo、Ni、Pb、Rb、Sn、Sr、Tl、U、V、Y、Zn和Zr)。分析了样品中元素浓度与当地基岩的关系,确定了它们的来源和地球化学旋回的相似性。土壤中的元素浓度变化很大,但一般在南极洲其他地方报告的最低值之内。Cd、Mn、Ni、Zn含量较高,但与当地成土岩中Cd、Mn、Ni、Zn含量基本一致,表明其为自然污染而非人为污染。土壤与岩石的化学成分对比表明,碱性玄武岩是土壤基质的产岩源,但也表明土壤中元素组成发生了较大的变化。考虑到当地的环境条件,土壤元素含量可能受到海洋来源输入和非常活跃的水文过程的影响,这些水文过程促进了淋滤和移动元素的去除。在全球气候变化的背景下,这两个过程可能特别重要,因为预测的温度、水分供应和夏季长度的增加将有利于矿物风化和增加元素的地球化学流动性。

Abstract: The aim of this research was to study the biodiversity of cyanobacteria and microalgae in hydro-terrestrial habitats from the area of Hornsund fjord (Svalbard archipelago). This research is particularly important, because hitherto no complex research (including all taxonomic groups) has previously been conducted on the cyanobacterial and microalgal flora in Arctic water ecosystems. The research was conducted during the summer seasons of 2011 and 2013. Shannon’s diversity index was used to describe species diversity and evenness. Data on cyanobacteria and microalgae were analyzed using the MVSP and PCA. Additionally, a basic analysis of the physicochemical properties of water in the studied ecosystems was performed. A total of 506 taxa were noted in the studied hydro-terrestrial habitats. The most numerous group was cyanobacteria, constituting 35% of all recorded taxa. Ochrophyta and Chlorphyta were almost equally numerous (percentage again as for cyanobacteria). Nineteen types of assemblages were noted in all studied hydro-terrestrial habitats. The diversity of cyanobacteria and microalgae and the assemblages formed by them were used to determine the characteristics of the studied ecosystems. Each type of water ecosystem was represented by specific phycoflora and assemblages. Ecological parameters along with biological data (the diversity of cyanobacteria and microalgae) allowed us to sort the studied hydro-terrestrial habitats by similarity. Our analyses clearly distinguished water ecosystem groups differing in species composition determining their trophic status. The research shows the usefulness of cyanobacteria and microalgae diversity defined by the Shannon-Weaver index for characterizing bodies of water and determining the trophic status of these habitats.
摘要/ Abstract摘要:本研究旨在研究霍恩松峡湾(斯瓦尔巴群岛)水陆生境中蓝藻和微藻的生物多样性。这项研究特别重要,因为迄今为止还没有对北极水域生态系统中的蓝藻和微藻菌群进行过复杂的研究(包括所有分类群)。这项研究是在2011年和2013年的夏季进行的。采用香农多样性指数来描述物种多样性和均匀度。采用MVSP和PCA对蓝藻和微藻数据进行分析。此外,还对研究生态系统中水的理化性质进行了基本分析。在研究的水陆生境中共发现506个分类群。数量最多的是蓝藻,占所有记录分类群的35%。绿藻门和绿藻门的数量几乎相同(百分比再次与蓝藻门相同)。在所有研究的水陆生境中发现了19种组合类型。利用蓝藻和微藻的多样性及其形成的组合来确定所研究生态系统的特征。每种类型的水生态系统都由特定的藻系和组合来代表。生态参数以及生物数据(蓝藻和微藻的多样性)使我们能够根据相似性对所研究的水陆生境进行分类。我们的分析清楚地区分了不同物种组成的水生态系统群,决定了它们的营养状况。该研究表明,蓝藻和微藻多样性的香农-韦弗指数定义的有用性表征水体和确定这些栖息地的营养状况。
