The Tea Bag Index (TBI) method was used to estimate the litter decomposition rate in peatland exposed for climate manipulation (increased temperature and reduced precipitation) at two contrasting sites differing water table depth (WTD) dynamics. To manipulate on peatland, prototyped Open Top Chambers (OTC) automated rain-out shelters were used. OTCs increased daytime air temperatures by ~1.7 °C driest plots an increase of precipitation, while average daily lower than 0.9 °C. However, cooled...
The Charales (stoneworts) are an ancient monophyletic group with conserved features same in ancesters as well present representatives.They considered to be closely related the ancestors of land plants.The taxonomy was delimitated on basis morphology and later by fossil characters well.Nowadays, higher taxa relatively defined their delimitation is supported molecular analyses.However, situation more problematic at subgeneric levels.The appearance often depends environmental conditions that...
Summary Plant community composition is recognized more and for playing an important role in ecosystem processes, such as C cycling. In particular, plant functional type ( PFT ) seems to have a key regulatory role, yet the underlying mechanisms interaction between s processes are still be identified. Here, we assess link dominant microbial consumers along calcareous poor extremely rich fen gradient western P oland. We particularly focussed on (testate amoebae), which can exert large effects...
Due to their unique flora, hydrology and environmental characteristics, peatlands are precious specific habitats for microorganisms microscopic animals. Their microbial network structure biomass crucial peatland carbon cycling, through primary production, as well decomposition mineralization of organic matter. Wetlands one the ecosystems most at risk from anthropogenic activities climate change. Most recent scenarios change Central Europe predict an increase in air temperature a decrease...
Abstract We investigated the relationships between testate amoebae (Arcellinida, Euglyphida), vegetation and water chemistry along environmental gradients in minerotrophic peatlands (fens) western Poland. hypothesized that: a) hydrochemistry significantly influences structure of amoeba communities, b) communities are more closely correlated with hydrochemical variables (environment) than data. Testate from 71 sample plots were together hydro‐chemistry hydrology based on 16 composition....
Understanding the influence of environmental factors on hydrobiota structure small aquatic ecosystems is essential for effective landscape management. In this study 165 water bodies situated in lowland high-productive agricultural western Poland we evaluate effect catchment, buffer zone, body and quality parameters macrophyte functional groups (nymphaeids, elodeids, pleustophytes, helophytes) zooplankton diversity. The potential pressure catchment ponds was high (mean Ohle index 140). For...
Abstract Peatlands are widely exploited archives of paleoenvironmental change. We developed and compared multiple transfer functions to infer peatland depth the water table (DWT) pH based on testate amoeba (percentages, or presence/absence), bryophyte presence/absence, vascular plant presence/absence data from sub-alpine peatlands in SE Swiss Alps order 1) compare performance single-proxy vs. multi-proxy models 2) assess models. Bootstrapping cross-validation showing best performing for both...
Ulva species are characterised by the capacity to achieve rapid biomass increase, which results in formation of "green tides", particularly nutrient-rich seawaters. Over last decade, large-scale mats has been increasingly observed freshwater systems Central Europe. Mass development ecosystems presents a growing burden spite its economic benefits. This study explores dynamics flexuosa with respect habitat conditions, using examples number water located Poland. Elevated temperature, pH and...
Hyperspectral remote sensing (RS) provides unique possibilities to monitor peatland vegetation traits and their temporal dynamics at a fine spatial scale. Peatlands provide vital contribution ecosystem services by massive carbon storage wide heterogeneity. However, monitoring, understanding, disentangling the diverse from heterogeneous landscape using complex RS signal is challenging, due its biodiversity distinctive plant species composition. In this work, we aim demonstrate, for first...
Abstract Peatlands are one of the most important ecosystems due to their biodiversity and abundant organic compounds; therefore, it is observe how different plant species in peatlands react changing environmental conditions. Sphagnum spp. main component considered as creator conditions favorable for carbon storage form peat. angustifolium fallax taxonomically very close species. To examine adaptability climate change, we studied morphology pigment content these two from manipulation sites...
In Europe peatlands are wetlands of postglacial origin. Because climatic changes and agricultural activities (i.e. drainage peat extraction), they one the most endangered ecosystems worldwide. Water mites well known as indicators changing environments in other such springs lakes. For our study we selected seven located North-Western Poland focused on water mite distribution associated habitat quality variables. We described fauna various microhabitats (aquatic semiaquatic) along...
Sphagnum peatlands host a high abundance of protists, especially testate amoebae. Here, we designed study to investigate the functional diversity amoebae in relation wetness and forest cover Baltic bogs. We provided new data on influence openness/wetness gradient communities, showing significant differences selected (TA) traits. Three key messages emerged from our investigations: 1) recorded an effect peatland surface openness traits that led us accept hypothesis TA differ according light...
Species of Ulva (Ulvaceae, Chlorophyta) are relatively common macroalgae in most coastal areas. In this paper, we examine inland aquatic ecosystems to determine relationships between the chemical parameters water and taxa present. Two groups samples freshwater were selected from: (i) habitats with high salinity levels, (ii) fresh or slightly saline waters. We showed that these two Ulva, which occupy distinct habitats, represent separate taxa. The first group represents flexuosa subsp....

In this study, we are testing a proxy for red and far-red Sun-induced fluorescence (SIF) using an integrated fuzzy logic modelling approach, termed as SIFfuzzy SIFfuzzy-APAR. The SIF emitted from the core of photosynthesis observed at top-of-canopy is regulated by three major controlling factors: (1) light interception absorption canopy plant cover; (2) escape fraction photons (fesc); (3) use efficiency non-photochemical quenching (NPQ) processes. our proposed validated approach that uses...
