Open AccessActive afforestation of drained peatlands is not a viable option under the EU Nature Restoration Law
The EU Nature Restoration Law (NRL) is critical for the restoration of degraded ecosystems and active afforestation of degraded peatlands has been suggested as a restoration measure under the NRL. Here, we dis...

Open AccessRecent climate change has driven divergent hydrological shifts in high-latitude peatlands
High-latitude peatlands are changing rapidly in response to climate change, including permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century using testate amoeba data from ...

Open AccessSynthesis of palaeoecological data from the Polish Lowlands suggests heterogeneous patterns of old-growth forest loss after the Migration Period
Human impact on Central European forests dates back thousands of years. In this study we reanalyzed 36 published pollen data sets with robust chronologies from Polish Lowlands to determine the patterns of larg...

Open AccessLong-term microclimate study of a peatland in Central Europe to understand microrefugia
Peatlands perform many important ecosystem functions at both the local and global scale, including hydrologic and climatic regulation. Although peatlands often act as climatic microrefugia, they have rarely be...

Open AccessHow Joannites’ economy eradicated primeval forest and created anthroecosystems in medieval Central Europe
During European states’ development, various past societies utilized natural resources, but their impact was not uniformly spatially and temporally distributed. Considerable changes resulted in landscape fragm...

Article
Widespread drying of European peatlands in recent centuries
Climate warming and human impacts are thought to be causing peatlands to dry, potentially converting them from sinks to sources of carbon. However, it is unclear whether the hydrological status of peatlands ha...

Article
Latitudinal limits to the predicted increase of the peatland carbon sink with warming
The carbon sink potential of peatlands depends on the balance of carbon uptake by plants and microbial decomposition. The rates of both these processes will increase with warming but it remains unclear which w...

Open AccessThe Impact of Experimental Temperature and Water Level Manipulation on Carbon Dioxide Release in a Poor Fen in Northern Poland
Peatlands are ecosystems for which carbon budget relies strongly on the meteorological and hydrological conditions. Here, using a manipulative field experiment, we measured ecosystem respiration (RECO) over two y...

Chapter
The Role of Peatlands and Their Carbon Storage Function in the Context of Climate Change
Peatlands are unique habitats that are covering around 3% of the land area and they are characterized by high sensitivity to climate. These very complex ecosystems impact both water and carbon cycle at local a...

Open AccessA novel testate amoebae trait-based approach to infer environmental disturbance in Sphagnum peatlands
Species’ functional traits are closely related to ecosystem processes through evolutionary adaptation, and are thus directly connected to environmental changes. Species’ traits are not commonly used in palaeoe...

Article
Hidden invertebrate diversity - phytotelmata in Bromeliaceae from palm houses and florist wholesalers (Poland)
Bromeliads accumulate water in the leaf axils (forming phytotelmata), which may then form a habitat for many animal species of both invertebrates and vertebrates. In temperate regions, bromeliads are commonly ...

Ecology of Testate Amoebae in an Amazonian Peatland and Development of a Transfer Function for Palaeohydrological Reconstruction
Tropical peatlands represent globally important carbon sinks with a unique biodiversity and are currently threatened by climate change and human activities. It is now imperative that proxy methods are develope...

Open AccessResponse of Sphagnum Peatland Testate Amoebae to a 1-Year Transplantation Experiment Along an Artificial Hydrological Gradient
Peatland testate amoebae (TA) are well-established bioindicators for depth to water table (DWT), but effects of hydrological changes on TA communities have never been tested experimentally. We tested this in a...

Article
Ecology of testate amoebae in peatlands of central China and development of a transfer function for paleohydrological reconstruction
Testate amoebae are a diverse and abundant group of protozoa that constitute a large proportion of biomass in many ecosystems and probably fill important roles in ecosystem function. These microorganisms have ...

Article
Holocene changes in climate and land use drove shifts in the diversity of testate amoebae in a subalpine pond
Testate amoebae that inhabit peat are sensitive indicators of water table position. In this study, we used testate amoebae in sediments from a mire in the western Alps (Lac du Thyl) to: (1) reconstruct the hyd...

Article
Contrasting Species—Environment Relationships in Communities of Testate Amoebae, Bryophytes and Vascular Plants Along the Fen–Bog Gradient
We studied the vegetation, testate amoebae and abiotic variables (depth of the water table, pH, electrical conductivity, Ca and Mg concentrations of water extracted from mosses) along the bog to extremely rich...

A rapid response of testate amoebae and vegetation to inundation of a kettle hole mire
Our palaeoecological study covers 73 years of history (1929–2002) of a kettle hole peatland inundated by water from a nearby, dammed lake. Testate amoebae, pollen and non-pollen palynomorphs (NPPs) were used t...

Chapter
Climate and Peatlands
Peatlands are an important natural archive for past climatic changes, primarily due to their sensitivity to changes in the water balance and the dating possibilities of peat sediments. In addition, peatlands a...

Multiproxy study of anthropogenic and climatic changes in the last two millennia from a small mire in central Poland
The Żabieniec kettle hole is the first peatland in central Poland analyzed quantitatively with four biotic proxies (plant macrofossils, pollen, testate amoebae and chironomids) to reconstruct the past environm...
