Screening of 1000-years old ice layers from the perennial ice block in Ghețarul de la Scărișoara Cave (Romania) revealed the presence of a diverse fungal community. The ice layers were deposited annually by freezing of percolating water containing debris from the surface. Using molecular techniques, based on DGGE fingerprinting of 18S rRNA gene fragments and sequencing, we detected fungi in presently-forming ( i.e. , 1-year old) and in 400 and 900 years old ice layers, respectively. The fungal community profiles in enriched cultures were relatively different compared to those derived from the corresponding environmental ice samples. The community profiles of fungi cultivated at 15°C were more complex compared to the DGGE profiles of fungi cultivated at 4°C. The fungal community was dominated by sequences belonging to the cryophilic yeast Mrakia stokesii in all ice samples. Another cryophilic fungus, Mrakia gelida , was only identified in recent ice samples. Sequences of more ubiquitous fungi Aureobasidium pullulans , Teberdinia hygrophila , Hyphoderma praetermissum , Leucosporidium yakuticum , Candida sp., Cercomonas sp., Thelebolus sp., alongside several yet uncultured fungi, were also identified
从罗马尼亚Ghețarul de la Scărișoara洞穴的多年生冰块中筛选1000年历史的冰层，发现存在多种真菌群落。这些冰层是每年由含有地表碎片的渗透水冻结而形成的。利用分子技术，基于18S rRNA基因片段的DGGE指纹图谱和测序，我们分别在当前形成(即1年)和400年和900年的冰层中检测到真菌。富集培养的真菌群落特征与相应环境冰样品的真菌群落特征相对不同。与4℃培养的真菌DGGE谱相比，15℃培养的真菌群落谱更为复杂。在所有冰样品中，真菌群落以属于嗜冷酵母Mrakia stokesii的序列为主。另一种嗜冷真菌，Mrakia gelida，仅在最近的冰样本中被发现。此外，还鉴定出了一些普遍存在的真菌，如鹅毛小孢子菌、嗜湿小孢子菌、早熟小孢子菌、雅库特白孢子菌、念珠菌、Cercomonas sp、Thelebolus sp，以及一些尚未培养的真菌

Mass movements have been one of the most efficient processes controlling the morphogenesis of the Outer (Flysch) Carpathians. Dated by 14 C method 180 landslides and related processes in the Polish Carpathians enabling to reconstruct mass movement chronology, confirm the thesis formulated by Starkel (1966), that the periods of acceleration of gravitational processes during the Late Glacial and the Holocene were connected with the stages of climatic humidity growths (Alexandrowicz, 1996; Margielewski, 2006; Starkel et al., 2013). Gravitational slope failures have often generated formation of non-karst caves. In the Polish part of the Outer Carpathians ca. 1400 caves, mainly of gravitational origin, have been explored up till now (Klassek, Mleczek, 2015). Part of these caves formed in the initial stage of landslide development, some ones formed during subsequent stages of landslide evolution (Margielewski, Urban, 2003; Lenart et al., 2013). Radiocarbon datings of speleothems allow us to reconstruct the stages of cave development and related mass movements. Pollen analysis of speleothems confirms these datings (Urban et al., 2015)
群众运动是控制外喀尔巴阡山脉形态形成的最有效的过程之一。用14c法测定波兰喀尔巴阡山脉180次滑坡和相关过程的年代，从而重建了岩体运动年代学，证实了Starkel(1966)提出的论点，即晚冰期和全新世重力过程加速的时期与气候湿度增长的阶段有关(Alexandrowicz, 1996;Margielewski, 2006;Starkel et al.， 2013)。重力坡失稳常导致非溶洞的形成。到目前为止，在外喀尔巴阡山脉的波兰部分已经发现了大约1400个洞穴，主要是重力起源(Klassek, Mleczek, 2015)。这些洞穴部分形成于滑坡发展的初始阶段，部分形成于滑坡演化的后续阶段(Margielewski, Urban, 2003;Lenart et al.， 2013)。洞穴化石的放射性碳定年法使我们能够重建洞穴发展的阶段和相关的群体运动。对洞穴植物的花粉分析证实了这些年代(Urban et al.， 2015)

In the northern part of the Polish Outer Carpathians, the Beskid Makowski Mts., four landslides formed during the Late Glacial have been identified so far. The landslide peat bogs formed within landslide depressions represent specific type of minerogenic mires filled down by organic-minerogenic deposit. Within the depositional sequences of these peats, palaeoenvironmental changes of the Late Glacial and the Holocene are recorded. The oldest of the studied fens started to form in the Oldest Dryas, the younger ones – in the Bolling (two peat bogs), Older Dryas and the Younger Dryas (Margielewski, 2003; Margielewski, 2006). In the sediments of the four landslide fens of the thickness varying from 4.5 m to 1.5 m, several logs were cored using the Instorf sampler. The laboratory study of the logs, reaching the deepest parts of the fens, included: palynological analysis, peat analysis (microscopic examination of organic deposits), grain-size (aerometric) analysis and content of minerogenic material (loss on ignition) analysis for 2.5 cm long intervals. Over 50 radiocarbon datings made in the studied logs (7-14 ones for each log), enable to date the horizons of lithological and pollen changes

Baradla Cave is a world heritage site situated in the northeastern part of Hungary. The cave itself formed supposedly from the Pliocene in Mesozoic marine carbonates and today has a total length of 25 km. The climate of the area is continental most of the precipitation arrives during early-summer, however, the main infiltration period is from November to April when precipitation exceeds evapotranspiration. According to recent monitoring data, temperature in the cave varies around 9.8°C throughout the year while the pCO 2 of the cave air follows a seasonal cycle. The CO 2 mixing ratio is highest (~4200 ppm) during the summer and lowest during in winter (~1600 ppm)

The Moldavian Plateau is a landslide prone region located in North-Eastern and Eastern Romania, the general morphostructural setting of this area consisting of a monocline with cuesta landforms. In the study area, the landslides are characterized by a strong temporal and spatial clustering, being influenced by the morphostructural setting and by the stratified layered rocks. The majority of the hillslopes affected by landslides are characterized by the presence of large old, relict landslides whose morphological signature is degraded by erosion and by younger landslides, the majority of them generating the retreat of the scarps in a retrogressive manner. In this paper we study the topological relations between several large landslides and archaeological sites for three selected settlements in the Moldavian Plateau, situated on ridges and hillslopes. Landslides and archaeological sites were mapped using high resolution LiDAR DEMs and extensive field validation activities were performed for stratigraphic and morphologic recognition of the landslides, deposits, and its relation with archaeologic sites

Many studies link the observed changes in local climate to the variations in the atmospheric circulation. A tested method of describing atmospheric circulation is by employing the weather or circulations types. This paper presents an objective classification of the atmospheric circulation affecting Romania, between 1951 and 2010, and its relation to the significant changes in the amount of precipitation after 1980

Lake sediments act as high-resolution archives of past climate and environments, able to record natural and anthropogenic driven changes, and their effects on the ecosystem. Here we discuss a new lacustrine record from Lake Ighiel (924 m a.s.l.), located in Apuseni Mountains, in an attempt to reconstruct the lacustrine dynamics over the last 6000 years and identify the main processes, which controlled the depositional system during specific phases of lake evolution. Based on 210 Pb and 14 C dating, X-ray fluorescence scanning (μ-XRF) measurements, long-core sedimentary logging and environmental magnetic proxies (susceptibility, natural and induced remanences) we discuss the following points: i) the characteristics of main lacustrine sedimentation phases; ii) the amplitude and interplay of processes controlling the depositional environment through time; iii) contribution of hydroclimatic forcing in explaining changes in the nature of lacustrine deposition

The effects of stress exposure in marine plankton are difficult to assess directly, because it is hard to replicate realistic conditions in laboratory experiments and because the physiological changes and adaptations in response to stress exposure occur over times scales that cannot be covered by direct observations. A viable alternative is provided by studies of marine microfossils. Census counts of microfossil assemblages allow reconstructions of community-level changes, whilst biometric studies provide information on the reaction of populations to different levels of stress

Present climate change issues have reached the top on the agenda of decision makers on national, regional and global level. Climate science directly contributes to socio-economic planning in our society despite the unavoidable uncertainties associated to the research tools we have used. The presentation reviews the research related to climate modeling as a tool for generating knowledge applied to past and present climate changes in Earth and human history and associated uncertainties from the perspective of future society development. The presentation shows that, in the context of adaptation to present climate change, ignoring knowledge together with related uncertainties about past and future climate might lead to high social, economic and environmental costs.
