Abstract:
Abstract Peat bogs and specially raised bogs are vulnerable ecosystems all over the world and they create refuges for some rare plant species. The aim of this paper is to provide information regarding the conservation status of five oligotrophic peat bogs situated in the volcanic mountains in the Oriental Chain of Carpathians, in Maramureș County. The studied peat bogs are: Tăul lui Dumitru (Dumitru Pond), Mlaștina Vlășinescu (Vlășinescu Peat bog), Iezeru Mare (Big Tarn), Tăul Chendroaiei (Chendroaiei Pond) and Tăul Negru (Black Pond), all of them have the status of nature reserve and under the IUCN categories they are included in category IV Habitat/Species Management Area (www.iucn.org, 2016). The analysis of the selected peat bogs reveals that all five of them have the vegetation included in the Natura 2000 priority habitat 7110* Active raised bogs. The conservation status of these peat bogs was evaluated and it is variable from moderate to very good conservation status.

Abstract:
The first data about Sphaeroceridae occurring on eight montane and foothill peat bogs of various types in the North Caucasus (Russia) are presented. A total of 38 species has been recorded and their affinity to peat-bog habitats is discussed. A single species is classified as a tyrphobiont, viz. the strongly brachypterous Pullimosina (Pullimosina) turfosasp. nov. being strictly associated with Sphagnum hummocks in peat bogs. This new species is described and illustrated in detail and its relationships, biology, and wing reduction are discussed. Only three species are considered tyrphophilous or probably tyrphophilous, viz. Ischiolepta nitida (Duda, 1920), Phthitia (Kimosina) longisetosa (Dahl, 1909), and Spelobia ibrida Roháček, 1983. The majority of recorded species do not have close affinity to peat bogs and are treated as tyrphoneutral, and Rachispoda hostica (Villeneuve, 1917) is probably tyrphoxenous due to occasional occurrence in a peat bog. Species composition of Sphaeroceridae on Caucasian peat bogs is discussed in comparison to those known from peat bogs in other parts of Europe. Taxonomic notes are given on Minilimosina (Svarciella) species of the M. vitripennis group. Six species (including P. turfosasp. nov.) are new additions to the fauna of Russia.

Abstract:
A regional survey of 60 raised bogs was made in eastern North America to determine the geographic patterns of bog landforms and gross peat stratigraphy. Three major types of bogs were identified: (i) midcontinental forested bogs with a longitudinal crest, radiating lines of forest growth, and an actively growing surface of loose Sphagnum hummocks, (ii) non-forested northern or maritime bogs with a convex or plateau shape, various networks of pools, hollows, and firm compact hummocks, and a more slowly growing surface that produces deeply humified bands or recurrence surfaces throughout the peat profile, and (iii) semiforested continental bogs with a forested crest, networks of linear hummocks and flat hollows on the lower flanks, and shallow expanding pools on the hollows. The peat stratigraphy on these semiforested bogs is also intermediate, with recurrence bands in the compact upper portions of the profile, becoming looser and more irregular toward the bottom. The geographic changes in landform patterns and gross peat stratigraphy indicate that forested bogs with a linear crest represent an early stage of bog development and are replaced in time by a nonforested plain with pools as changes in the slope and the hydrologic properties of the surficial layers of peat restrict runoff and infiltration, producing a rise in the water table. Thus on a regional scale autogenic bog processes may be as important as climate in controlling bog patterns and peat stratigraphy.

Abstract:
Pinus mugo shrubs on peat bogs in the Tatra National Park (TNP) were for the first time described as a separated plant association by Obidowicz (1975) from only two mires. Since then, there have been no studies on peat bogs in the TNP and they have not been mentioned in the list of vegetation types of the Park. The research regarding the dwarf pine shrubs on mires in the Tatra Mountains was carried out in 2019. We mapped all patches of such vegetation (total – ~2 ha) on which we made 26 relevés. P. mugo shrubs on peat bogs occur within the complex of mire habitats, such as Norway spruce bog woodlands, raised bogs and poor fens. The shrub layer is dominated by Pinus mugo with admixture of dwarfish Picea abies. Typical plants of the herb layer are Vaccinium myrtillus, V. vitis-idaea, Eriophorum vaginatum and Oxycoccus palustris, whereas the most common mosses are Sphagnum magellanicum, S. capillifolium, S. russowi, Pleurozium schreberi. P. mugo shrubs on peat bogs in the TNP belong to the association Sphagno magellanici-Pinetum mugo.

Abstract The paper deals with the possibilities of different wave frequency antennae applications for estimation of the depth of peat deposits and detection of peat layers with different physical characteristics. We employed a GPR system “OKO-2” (“Logical systems”, Russia) with 250 MHz, 700 MHz, and 1700 MHz shielded antennae. The surveys were conducted in 2017–2019 within the pristine and drained raised bogs and swamp forest in the south taiga subzone of Western Siberia to assess the spatial differentiation of the peat deposit and the modern peat accumulation rate within drained bogs. The peculiarities of field surveying, GPR data processing and interpretation are shown. Based on GPR data analysis the influence zone of Bakchar bog and modern peat accumulation within drained bogs were assessed. We noted that the Bakchar bog has a vast zone of influence reaching 700 m from the bog border where peat accumulation is observed. The modern peat accumulation is observed within Bakchar the bog. Drained sites of Ust-Bakchar bog are characterised by the absent peat accumulation or degradation of the peat deposits.

Abstract:
Peat humification character in two ombrotrophic bogs depending on peat properties Study of the living organic matter humification process is essential for understanding of the carbon biogeochemical cycle. The aim of this study is to determine the relations between peat properties and humification degree in two peat profiles in ombrotrophic bogs in Latvia, to identify the links between peat age, decomposition degree, peat properties, peat botanical composition and peat properties. The peat diagenesis process was described using multiproxy analysis of peat age, botanical composition, elemental composition, elemental ratios of the peat organic matter and peat alkaline extracts. This approach supports a better understanding of the peat properties and their relation both to peat decomposition processes, and also to original living organic matter. Multiproxy study of peat properties supports development of peat humification indicators.

Abstract:
Based on the analysis of the botanical composition of the organic-mineral soil layer and peat, dendrochronological and radiocarbon datings, we performed the reconstruction of the development of six pine wooded sphagnum bogs located in the boreal zone of Russia. Most of the bogs under study followed the endogenesis patterns with the vegetation cover gradually changing, peat layer growing, substrate trophicity declining and shrub-sphagnous vegetation forming under modern conditions. Emerging pyrogenic layers and charcoals in the peat indicate that the study sites were constantly affected by fires, which periodically interrupted the endogenous development of the bogs, especially during the warmest Holocene periods.

Abstract:
Organic matter has accumulated as peat in bogs since the last glacial retreat and its anaerobic decay by microbial communities produces methane (CH₄). CH₄ released from northern Boreal peat currently represents a significant proportion of the global budget but their contribution under future climates is uncertain. It is the surface peat 0-500 mm below the water table that is most important for emissions. This study aims to describe the vertical distribution of the gases CH₄, CO₂, O₂ and Ar and their fine scale (0.6 mm) variability in surface peat cores from a rain-fed bog using Quadrupole Mass Spectrometry (QMS). Direct links between the physical structure of peat and distribution of microbial communities have been investigated to identify the determinants of gas distribution.

Abstract:
Human activity has affected metal emissions to the atmosphere on a global scale for several thousand years, resulting in widespread contamination of the environment with toxic heavy metals such as Pb and Hg, thereby threatening both human and environmental health. In recent years ombrotrophic peat bogs have been used to study the changing rates and sources of atmospheric metal deposition, as they receive all their water and nutrients from the atmosphere by dry and wet deposition alone. Cores from such bogs have proved especially useful as archives of atmospheric Pb deposition as Pb is essentially immobile in ombrotrophic peat. The work described in this thesis is primarily concerned with the use of ombrotrophic peat bogs to investigate environmental contamination in Scotland during pre-industrial, industrial and post-industrial (i.e. ca. post-1970 A.D.) times. Cores were collected from ombrotrophic peat bogs at four different geographical locations (Carsegowan Moss, SW; Flanders Moss, W Central; The Red Moss of Balerno, E Central; Turclossie Moss, NE) in Scotland. Air-dried peat samples were dry-ashed and dissolved using microwave-assisted HF IHN03 digestion. Elemental concentrations (e.g. AI, As, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, P, Pb, S, Sb, Sc, Se, Ti, V, Y, Zn and Zr) and Pb isotope ratios (e.g. 206PbP07Pb) were determined using ICP-OES and ICP-MS as appropriate. For Hg determination, samples were digested with HN03/H2S04 and then analysed by CV AAS. Certified reference materials (e.g. Ombrotrophic Peat (NIMT/UOE/FM001), Canadian Peat (1878 P), Bush Branches and Leaves (DC73349), Peach Leaves (GBW 08501) and Coal (BCR CRM No. 40 and NBS SRM 1635) were used for quality control purposes. The distribution and behaviour of the potentially toxic trace elements (As, Cd, Co, Cr, Cu, Hg, Ni, Sb, Se, V and Zn) and of major elements (Ca, Fe, Mg, Mn, P and S) within the four ombrotrophic peat bogs was investigated and there was strong evidence that Ca, Fe, Mg, Mn, P, S, Se and Zn were mobile in ombrotrophic peat, while As, Cd, Co, Cr, Cu, Hg (at least during industrial and post-industrial periods), Ni, Sb and V, like Pb, were essentially immobile in ombrotrophic peat. Deposition records of conservative lithogenic elements (e.g. concentrations of AI, Sc, Ti, Y and Zr) that occur predominantly in soil dust were also investigated and the chosen conservative elements Sc, Ti and Zr were used in calculations to estimate anthropogenic enrichments of As, Cd, Co, Cr, Cu, Ni, Pb, Sb and V in peat bog profiles. 210Pb- and 14C- dated peat cores were used to reconstruct historical records of atmospheric anthropogenic As, Cd, Co, Cr, Cu, Ni, Pb, Sb and V deposition (since the pre-Roman (i.e. to ca. 380 B.C.)/Roman period) and atmospheric Hg deposition (since the onset of the industrial period) across Scotland. For Pb, on the basis of Pb isotopic composition (e.g. 206PbP Pb), clear indications of contamination during the preRoman/Roman and Mediaeval periods were attributed to the mining and smelting of Pb ores (from Britain and elsewhere in Europe). During the industrial and post-industrial periods, variations in the relative importance of contributions of anthropogenic Pb from different sources were apparent. From ca. the early 17th century A.D. at three of the peat bog sites, the mining and smelting of indigenous Scottish Pb ores, until the early 20th century A.D., were found to be the most important sources of anthropogenic Pb deposition. In contrast, at the most southerly site (Carsegowan Moss), influences from the use of both British Ph ores and imported Australian Ph ores (in more southern parts of Britain) since the late 19th century A.D. were evident. At each of the sites, the increasing importance of Australian-Ph-influenced car-exhaust emissions from the 1930s to late 1990s A.D., along with significant contributions from coal combustion (until the late 1960s A.D.) was evident. For Sb, in general, similarities between the major trends in the concentration profiles of anthropogenic Sb and Ph suggested common sources of these two elements. Perturbations in the anthropogenic Sb/Pb ratios since ca. 1800 A.D., however, were attributed to temporal variations in the relative importance of atmospheric emissions from different sources such as Ph ore mining/smelting, coal combustion and, in recent decades, automobile-related use of compounds of Ph (in leaded petrol) and of Sb (in brake linings). For Hg, in general, during the industrial and post-industrial periods, coal combustion and waste incineration, respectively, were likely to be the most important sources of Hg. For As, clear indications of contamination during the Mediaeval period were probably attributable to the mining and smelting of Ph and Cu ores, and for As, Cd, Co, Cr, Cu, Ni and V, during the industrial and post-industrial periods, a variety of sources (e.g. metallurgical activities, coal and oil combustion, use of phosphate fertilisers and waste incineration) were important to varying extents. Also, in recent years, atmospheric Cu emissions from automobile-related use of compounds of Cu (in motor oil, brake linings and tyres) may have been important. Inter-site and inter-elemental comparison of records of atmospheric metal deposition across Scotland indicated that, in general, atmospheric As, Cr, Hg, Ph and Sb deposition was greatest during the industrial period (between the late 1880s and late 1960s A.D.) and atmospheric Cd, Co, Cu, Ni and V deposition was greatest during the industrial and post-industrial periods (between ca. 1900 and the early 2000s A.D.), although increases in As, Co, Cr, Hg, Ph and Sb deposition were earliest (during the late 19th and early 20th century A.D.) at the most southerly site (Carsegowan Moss). During the industrial and post-industrial periods, levels of As, Ph and Cd contamination were generally highest in the south of Scotland, Cu, Co and Sb in south and central Scotland, and Cr, Ni and V in central Scotland. Overall, the existence of a south to north As, Cd, Co, Cr, Cu, Ni, Ph, Sb and V pollution gradient in Scotland was evident.

Abstract:
The primary aim ofthis project was to use a range of molecular markers to estimate genetic diversity levels of a range ofcommon plant species in peatbogs, in cut and uncut areas of six differentbogs across Northern Ireland. The main species studied were the moss Polytrichum commune, the ericaceous angiosperm Calluna vulgaris, and the sedge Eriophorum vaginatum. For the moss, levels of genetic diversity were lower in fragmented populations, as predicted by population genetic theory. For the two higher plant species, no decrease in genetic diversity was found at the cut sites. Calluna vulgaris showed an increase in genetic diversity at cut sites, possibly associated with the effects of a substantial, soil seed bank, while for Eriophorum vaginatum all populations examined had a similar level of genetic diversity. The differences observ~d between the three species can be related to their different life . history traits. E. vaginatum and C. vulgaris are long lived species with the capacity for clonal growth and any detrimental effect of habitat fragmentation is likely to take many more generations to become apparent, if such an effect is to be observed. P. commune is a bryophyte where the haploid gametophyte is the dominant generation, with a short life span and a small dispersal distance compared to C. vulgaris and E. vaginatum, it is not unexpected that such a species would be the first to display the detrimental signs of habitat fragmentation. Based on the findings ofthis study, recommendations are made for the efficient conservation and management of peat bogs.

Abstract:
For the first time, presented within this thesis, is an investigation into the species richness and community composition of a group of beautiful but taxonomically challenging green algae - the desmids. This thesis represents the first account of a systematic sampling approach for desmid species and community assemblages in relation to national and local environmental variation. Sampling was focused on intact blanket mire with the aim of capturing a rich baseline dataset of desmid diversity. Previous works had highlighted desmids as being especially species rich in these acidic, nutrient-poor peatland habitats. A nested sampling approach was used to collect desmids from blanket mire microhabitats along the hummock-pool microtopographic gradient, from sites nationally within Scotland. This approach revealed remarkable species richness with 202 taxa sampled, including one new species. Distinct desmid communities were found to be strongly associated with the hummock-lawn-pool microhabitats within patterned blanket mire. This topographic aspect of peatland structure and its associated co-variables (such as pH and water table depth) also have a strong link to desmid diversity with the richest communities being found in association with a consistent supply of water close to the water table. Generally, ‘unstable' habitats supported lower desmid diversity. A field experiment was established to investigate the effects of drainage and drain restoration on desmid communities. This highlighted the loss of desmid diversity in drained peatlands and a successful but slow recovery of diversity upon restoration through drain blocking. The findings of this PhD project provide an understanding of the spatial scale of desmid community structure and the factors which are important for informing future conservation strategies for peatland habitats to maintain the diversity of this fascinating microbial group.

Abstract:
Microbial nitrogen (N2) fixation supplies important nitrogen inputs to boreal peatlands, extremely oligotrophic ecosystems dominated by Sphagnum mosses. In this study, we coupled major and trace nutrient analyses and rate measurements to characterize interactions between N2 fixation and CH4 cycling at the S1 peat bog in Marcell Experimental Forest and the Zim bog (Minnesota, USA). Total dissolved inorganic nitrogen (NO3-+NO2-+NH4+) and phosphate were both consistently < 2 μM in the porewater of surface peat, indicating severe nutrient limitation. While dissolved Fe was fairly abundant (18-35 mM), Mo, V and Cu were scarce (2-40 nM), suggesting that alternative metalloenzymes containing Fe in place of other metals may be favored. Rates of diazotrophy measured by both 15N2 incorporation and the acetylene (C2H2) reduction assay (ARA) were 7-fold higher under anoxic vs. oxic incubations conducted at both 4°C and 25°C. No significant difference in N2 fixation rates measured by either method was observed with or without the amendment of 1% CH4 at 25 °C; however, a significant inhibitory effect by methane was seen at 4°C in material from the S1 bog hollows. Anoxic 15N2 incorporation was 3-4x higher in treatments lacking acetylene, suggesting that the ARA likely underestimates N2 fixation by inhibiting diazotrophs sensitive to C2H2. Aerobic methanotrophy was also inhibited by 1% C2H2 when incubated under oxic conditions. No observations for the production of ethane (C2H6) were detected during the ARA, a biomarker for alternative nitrogenase activity. Major differences in ARA rates were observed to vary locally within microhabitats and between two bogs. In June 2014, peat sampled from hollows incubated under anoxic conditions showed the highest ARA rates (94.9 ± 11.0 nmol C2H4 g-1 moss dry mass hr-1), while the lowest rates were observed in ix hummock samples incubated under oxic conditions (5.1 ± 0.8 nmol C2H4 g-1 moss dry mass hr-1) in the S1 bog (T3 site). Observed rates have the potential to be a function of oxygen concentrations and or water content. ARA rates in all microcosm treatments were significantly lower at Zim bog compared to the S1 bog. The developed conversion factor between the regression of 15N2 and ARA in this study was 3.9 and agrees with the theoretical conversion factor as well as previous studies of soils and forest mosses.

The work described in this thesis is primarily concerned with (i) the development of analytical methods for the determination of inorganic elements in peat, (ii) the production and analysis of a certified peat reference material, and (iii) the application of methods and procedures to the generation and interpretation of elemental profiles in cores from the largest ombrotrophic peat bog in Scotland. The effects of sample preparation on the determination of inorganic elements in peak samples were thoroughly investigated. The analytical methods and quality assurance procedures developed using the certified reference material were applied to the analysis of two Flanders Moss peat cores that had been collected by different coring techniques. An offset between the elemental profiles of the two cores was attributed to loss of surface material in the case of one, confirmed by stable (206Pb/207Pb) and radioactive (210Pb) isotopic analysis. The depth profiles of the various elements were interpreted in terms of influences such as nutrient uptake and recycling, anthropogenic inputs from industry, energy generation and transport, soil dust, and post-depositional remobilisation and redistribution. For Pb, for which a record for atmospheric deposition was retained, the relative contributions of different sources (e.g. smelting, coal combustion, car-exhaust emissions) during the industrial era were assessed using Pb concentration and 206Pb/207Pb ratio variations in 210Pb-dated peat. The importance of atmospheric Pb deposition prior to the introduction of leaded petrol was confirmed and, in the more distant past, a small Pb peak at a depth of ~1 m was tentatively attributed to Pb mining and smelting activities during the period of the Roman Empire.

Abstract:
Les tourbières sont communément utilisées comme archives de dépôts de mercure (Hg). De nombreuses études ces dernières décennies ont montré que les taux d’accumulation de Hg (HgARs) ont augmenté en réponse à l’industrialisation. Les signatures isotopiques en Hg se révèlent très utiles pour mieux caractériser les dépôts de Hg. Elles ont permis de montrer que les dépôts secs de Hg élémentaire gazeux (GEM) dominent les dépôts de Hg sur la tourbière du Pinet. L’analyse d’échantillons de tourbe provenant de plusieurs tourbières en hémisphère nord montre que les dépôts secs de GEM dominent globalement les dépôts de Hg. Les tourbières pourraient donc être utilisées comme archives à la fois des dépôts humides et des concentrations en GEM pendant l’Holocène. On présente la première reconstruction quantitative des concentrations passées en GEM à partir de carottes de tourbe. L’impact de l’Homme sur le cycle du Hg a eu pour conséquence une augmentation graduelle des concentrations en GEM de 0,2 (10 000 – 4000 BP) à 3,5 ng m-3 (20ème siècle), accompagnée par des modifications de signatures isotopiques du Hg atmosphérique. Cette première utilisation de tourbières comme archives de concentration et d’isotopie du GEM est prometteuse, et devrait être étendue à la période pré-anthropique pour étudier les variations naturelles du cycle du Hg pendant l’Holocène
During the past few decades, peatlands were successfully used to investigate historical mercury (Hg) deposition. The chronology of Hg accumulation rates (HgARs) to peatlands is well constrained, with recent increases in HgAR associated with anthropogenic Hg emissions and deposition. The use of Hg stable isotopes in peatland ecosystems provides new opportunities to better characterize and understand historical Hg deposition. In an extensive study conducted at the Pinet peat bog (French Pyrenees) we identify gaseous elemental Hg (GEM) dry deposition, via foliar uptake, as the dominant Hg transfer pathway from the atmosphere to peat vegetation. Based on the Hg isotope analysis of multiple northern hemispheric peat records, we find that GEM dry deposition dominates Hg deposition globally. We suggest that peatlands can be used as archives of both past Hg wet deposition, Hg dry deposition and GEM concentration. We present the first quantitative reconstruction of historical atmospheric GEM concentrations using peat archives from the Pyrenees. The Human impact on Hg cycling caused a gradual increase in GEM concentrations from 0.2 (10,000 – 4000 BP) to 3.5 ng m-3 (20th Century) and was accompanied by a change in atmospheric Hg isotope signatures. This first comprehensive study on Hg isotope deposition to peatlands is promising and should be extended to pre-anthropogenic times to investigate natural variations in atmospheric Hg dynamics during the Holocene

Abstract:
The Hudson Bay Railway (HBR) is a 510 mile railway completed in 1929 in northern Manitoba, Canada. It connects domestic locations in North America with international destinations through the Port of Churchill. Permafrost was encountered during construction at milepost 136 in isolated peat bogs which continued in a gradual northward transition from discontinuous to continuous permafrost. Over the past 80 years, warming climate combined with poor engineering properties of the railway embankment material has resulted in further thawing of the discontinuous permafrost leading to differential settlement along the rail embankment and high annual maintenance costs. In a bid to understand the geothermal regime of the embankment, underlying subsurface condition, and to seek for solutions to stabilize the embankment, extensive work has been done from 1977 to the present time. This paper seeks to review reports of the past projects and compare the results against current conditions at selected test locations.

Abstract:
Oy Alholmens Kraft Ab, with its unique combination of owners, was founded for the purpose of building a power station at Pietarsaari on the west coast of Finland. The power utility companies initiated the co-operation with the saw-, pulp and paper mill owners with the goal of finding a solution which maximized biomass utilization through co-firing with other fuels, to produce steam and heat in a utility sized power plant. Concept development resulted in a 240 MWe circulating fluidized bed unit with a flexible and demanding combination of fuels. The Alholmens Kraft power plant supplies process steam to the nearby UPM-Kymmene paper mill, and for district heating in Pietarsaari. The plant produces electricity for the power company owners in Finland and in Sweden. The CFB boiler steam capacity is 550 MWth (1875 MMBtu/hr), giving a maximum electric power of 240 MWe. When commissioned in autumn 2001 the boiler was one of the largest CFB boilers in the world, and the largest biofuel-burning CFB. The Alholmens Kraft CFB boiler is a multi-fuel boiler, whose main fuels are bark, wood residue and peat, with coal as a back-up fuel. Due to its location at the pulp and paper mill, high reliability and low emissions were the most important design criteria for the boiler. Steam production for the mill must be ensured all year-round, apart from during the mill’s short annual service shutdowns. Another important design consideration was the controllability of the boiler due to Nord Pool electricity production requirements. Typical regular load variation is between day and night but sometimes the load change speed requirement is quite high. This paper presents the Alholmens Kraft power plant application, and its very smooth start-up and operational experience during the first year with different fuels and fuel combinations at various load levels. The paper also describes how well the large boiler has performed with regard to the strict emission limits. The selection of design fuel contributes well towards the target for net CO2 reduction, but it also places huge requirements in terms of fuel purchasing and logistics. The volumetric fuel consumption by the boiler at full load is 1000 m3/h (35 000 ft3) of biofuel. More coal, the support and reserve fuel, is used in spring as weather conditions may cause availability problems with peat, before the new peat can be harvested and dried at the peat bogs. Coal is always available at the site. This paper presents the first year’s operational experience of the fuel logistics chain. The successful Alholmens Kraft CFB boiler project is an excellent example of the very wide fuel flexibility that is possible in a CFB unit.

Abstract:
Teichi bog is largest intact moss bog in the Baltics states. The article considers the hydrological exchange process of the bog and surrounding areas. It plays an important role in the ecosystem, as well as a factor in stabilizing the water level, as bog peat in its natural state contains 88%-97% water. It belongs to raised bogs, since its upper layer is located above the surrounding relief. Replenishment of water resources in the Teichi Nature Reserve occurs mainly due to precipitation. In turn, the bog with surface runoff and groundwater flow returns excess moisture, thus feeding nearby streams. The reserve area and surroundings modeled in the Groundwater Vistas environment over a 35 km ? 40 km area, with a plane approximation step of 20 m. The hydrogeological model contains seven layers, 24.5 million nodes. The model includes several rivers, lakes and a wide network of drainage ditches, both embedded in the relief and attached as boundary conditions. A novelty is the assignment of different filtration coefficients to the bog. The process of water movement studied by calculating water balances, as well as by performing particle tracing simulations. Result of the research - it was found that there is an intensive interaction of the bog with nearby watercourses. The protection zone of the bog was determined using the results of tracer simulation - movement time and trajectory over a period of 25 years.

Abstract:
Bogs of Darwin Biosphere reserve (southern NW Russia) represent sustain ecosystem balance on an outstandingly large scale. Dynamics of the bog metabolism and structure should be estimated both under the influence of the Rybinsk reservoir and beyond it (in terms of natural evolution), although these cannot always be distinguished clearly. Forested bog areas are most sensible ecosystems to trace decadal or centennial dynamics of the landcover. Longstanding observations of the geobotanical and forest structure have been continuously performed in Darwin Nature Biosphere reserve from 1947 to 2012 within a series of the model grounds. Changes of parameters of sphagnous pinewood through 65 years are overviewed, based on the on-site censuses and, partially, remote sensing data. During the first decades of observations (1947-1991) the accounted forest stand gained maturity, and ultimately tree died off numerously. Pinewood shrinkage was noticed in 1990-s, due to the reached tree age limits (in bog conditions), and the durative drought to have affected those years. At present mature and undergrowth pine stand covers almost 1.7 times less of the surrounding 500-area around the model ground, than 40-50 years ago, mainly due to the tree dying off in 1990-2000. A 20-year forest regrowth brings repopulation of pine on the site, which gradually spreads over the bog around the model ground. The assessed changes of qualitative and quantitative properties of the microlandscape enable to trace ecosystem function transformation on the local level, i.e., enhancement of peat soil humidity, hygrophytic vegetation appearance, and reformation of habitats suitable for bog-nesting birds, as the pine forest decayed.

Full text
Abstract:
Historic maps are an important primary source which can be utilized in the reconstruction of environmental variables of the pre-industrial landscape. However, methodological constraints have hitherto prevented large scale and systematic approaches. In this paper a novel methodology is presented, which documents the usefulness of the maps in the study of paleo-hydrology and thus serves a better understanding of the conditions for agricultural production under pre-drainage conditions. The methodology is developed based on eighteenth and nineteenth century maps from a 100 km2 study area in one stream catchment in East Jutland, Denmark. It combines information from two types of historic maps in order to correlate computed soil hydrology (wetness index) and recorded historic land-use. The calculated wetness indexes are derived from contour lines on topographic (military) maps (in Danish: Høje Maalebordsblade), whereas the spatial overlays are land-use classes from economic maps (in Danish: Matrikelkort - Original 1). This study demonstrates – for the first time - that the wetness index is explanatory for the agricultural suitable/non-suitable dichotomy (tilled land versus “wetland”: meadows, fens, and peat bogs) on the historic economic maps. Furthermore, the study shows that pre-industrial arable areas were stretched to their limits in respect to cropping wet soils in this agricultural dominated landscape. The study confirms the existing belief that the historic economic maps constitute the best available source of these mosaic-landscapes for periods before the intense subsurface tile drainage began. This finding opens for further methodological development and up-scaling using automatic feature detection, contour line extraction and text recognition of historical maps.
