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.

In our study, we investigate changes in environment and climate that occured during post-Holsteinian period in Krępa palaeolake (eastern Poland). To achieve this goal we reconstructed summer temperature at the time using Chironomidae larvae head capsules and pollen data. This is first research from Central Europe with both chironomids and pollen used to trace climate change through post-Holsteinian period. We hope to encourage scientific community to carry out further research in the region.

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.

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 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.

We looked at man-made radioactive substances in the Arctic lower atmosphere. We found that airborne plutonium is linked to environmental processes such as local resuspension, biomass burning and long-range transport from remote areas. However, the presence of americium and neptunium in the air could not be explained by natural mechanisms, suggesting a recent nuclear release. We used simulated trajectories to identify the most likely transport pathways from northern Eurasia.

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.

The spring onset and growing season dynamics during the Late Glacial period in the Baltic region were reconstructed using the micro-phenology based on dwarf birch subfossil leaf cuticles. The comparison of pollen- and chironomid-inferred past temperature estimations with spring onset, growth degree day, and plant macrofossil data shows coherent patterns during the cooler Older Dryas and warmer Bølling–Allerød periods but more complicated climate dynamics during the Younger Dryas cold reversal.

Annually banded lake sediment can track environmental change with high resolution in locations where alternatives are not available. Yet, information about chronology is often affected by poor appearance. Traditional methods struggle with these records. To overcome this obstacle we demonstrate a Bayesian approach that combines information from radiocarbon dating and laminations on cores from Columbine Lake, Colorado, expanding possibilities for producing high-resolution records globally.

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.

We present a continental dataset of pollen accumulation rates (PARs) collected by pollen traps. This absolute measure of pollen rain (grains cm−2 yr−1) has a positive relationship to current vegetation and latitude. Trap and fossil PARs have similar values within one region, so it opens up possibilities for using fossil PARs to reconstruct past changes in plant biomass and primary productivity. The dataset is available in the Neotoma Paleoecology Database.

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.

Short summary
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 substantial as well as small but sustained increases in alkalinity. Limited recovery was evident ~30 years post-pollution.
The long-term effects of alkalinisation upon peatland ecosystem functioning remains poorly...
