Short summary
We used a multi-proxy approach combining peat, tree ring, climate, and historical records to reconstruct >2,300 years of peatland dynamics in a Central European region. Results show a human-induced shift from alder to pine forest due to land use change and acidification, stressing the importance of long-term records for peatland conservation.

Peatlands are large stores of carbon but are vulnerable to human activities and climate change. Comprehensive peatland data are vital to understand these ecosystems, but existing datasets are fragmented and contain errors. To address this, we created Peat-DBase — a standardized global database of peat depth measurements with > 200,000 measurements worldwide, showing average depths of 144 cm. Peat-DBase avoids overlapping data compilation efforts while identifying critical observational gaps.

We integrated palaeoecological and geochemical data to discern the impact of catastrophic events on the development of peatlands within pine monocultures. An approach that integrates these methods is not commonly employed but offers a more comprehensive understanding of past ecosystem transformations. We used multi-proxy research of the peat core and neodymium isotope record. We support the results of our analyses with the recognition of statistically significant critical transitions.

We studied a peatland in northern Poland to see how climate and natural ecosystem changes shaped it over the past 11,500 years. By analysing preserved plants and microscopic life, we found clear shifts in wetness linked to climate and internal development. This longest complete peat record in the region shows how peatlands help us understand long-term environmental change and their future resilience to climate change.

The long-term effects of alkalinisation upon peatland ecosystem functioning remains poorly understood. Using palaeoecological techniques, we show that intensive cement dust pollution altered vegetation cover and reduced carbon storage in an Estonian peatland. Changes also occurred during the 13th century following agricultural intensification. These shifts occurred following two-to-threefold alkalinity increases. Limited recovery was evident ~30 years post-pollution.

The study combines palaeoecological, dendrochronological, remote sensing and historical data to detect the impact of forest management and climate change on peatlands. Due to these changes, the peatland studied in this paper and the pine monoculture surrounding it have become vulnerable to water deficits and various types of disturbance, such as fires and pest infestations. As a result of forest management, there has also been a complete change in the vegetation composition of the peatland.

In our study, we investigate what changes in environment and climate occured during post-Holsteinian period in Krępa palaeolake in Eastern Poland. In order to achieve this goal we reconstructed summer temperature at that time with the use of Chironomidae larvae head capsules. This is first research from Central Europe in which we use chironomids to trace climate change through pre-Holocenian period. We hope to encourage scientific community to carry out further research in the region.

We provide a new global data set of charcoal preserved in sediments that can be used to examine how fire regimes have changed during past millennia and to investigate what caused these changes. The individual records have been standardised, and new age models have been constructed to allow better comparison across sites. The data set contains 1681 records from 1477 sites worldwide.

Młynek Lake, located near the village of Janiki Wielkie (in the Warmia and Masuria region of north-east Poland) has been selected for multi-faceted palaeoenvironmental research based on a precise radiocarbon scale. Bottom sediments of this reservoir also contain unique information about anthropogenic activity and climate changes during last 2400 years.

We developed an up-to-date European map of groundwater pH and Ca (the major determinants of diversity of wetlands) based on 7577 measurements. In comparison to the existing maps, we included much a larger data set from the regions rich in endangered wetland habitats, filled the apparent gaps in eastern and southeastern Europe, and applied geospatial modelling. The latitudinal and altitudinal gradients were rediscovered with much refined regional patterns, as is associated with bedrock variation.

Western Siberian permafrost peatlands store vast amounts of carbon and play a crucial role in global climate regulation. Based on the comparison of palaeoecological records from two microhabitats from discontinuous permafrost peatlands, the authors explore environmental shifts during rapidly changing climate conditions during the last two centuries. The study presents data from rapidly disappearing landscapes. The results emphasize the nonlinear and spatially variable nature of permafrost thaw’s impact on peatlands. Permafrost is regarded as one of the climate tipping points, and this study provides insights into potential consequences of permafrost destabilization for northern peatlands ecosystems.

Short summary
Western Siberian peatlands regulate global climate, but their response to permafrost thaw remains poorly studied. Our study analyzed peat cores from a peat plateau and a lake edge to track changes over two centuries. We found that permafrost thawing, driven by rising temperatures, altered peatland hydrology, vegetation, and microbial life. These shifts may expand with further warming, affecting carbon storage and climate feedbacks. Our findings highlight early warning signs of ecosystem change.
