Long‐Term Ecological Baselines and Critical Thresholds in Ombrotrophic Peatlands of Europe: Implications for Restoration Strategies Open
Maintaining appropriate peatland hydrology, notably through the regulation of the depth to water table (DWT), is crucial for peatland conservation, restoration, and the mitigation of greenhouse gas (GHG) emissions. We assess the long‐term …

Fire activity in the northern Arctic tundra now exceeds late Holocene levels, driven by increasing dryness and shrub expansion Open
Tundra ecosystems are characterized by small, rare and infrequent fires due to cold, often waterlogged conditions, and limited biomass. However, ongoing climate warming and drying in northern soils and peatlands are contributing to increas…

Climate and water-table levels regulate peat accumulation rates across Europe Open
Background Peatlands are globally-important carbon sinks at risk of degradation from climate change and direct human impacts, including drainage and burning. Peat accumulates when there is a positive mass balance between plant productivity…

Synchronizing Pu fallout and inorganic fly ash particles record in Northern Hemisphere peatlands Open
This study examines two critical markers of anthropogenic activity - plutonium (Pu) and inorganic fly ash particles, specifically spheroidal aluminosilicates (SAPs) and mullite - to evaluate their patterns of distribution across the Northe…

Climate Warming and Deglaciation Drive New Peat Formation in the Southern Alps, Aotearoa/New Zealand Open
Nascent peatlands represent an emerging, nature‐based carbon sink in the global climate system. A warming climate and changing precipitation regime could drive peat initiation beyond the current latitudinal and altitudinal boundaries of th…

The impact of Lusatian Urnfield and subsequent prehistoric cultures on lake and woodland ecosystems: insights from multi-proxy palaeoecological investigations at Bruszczewo, western Poland Open
The Lusatian Urnfield culture (LUc, Lausitzer Kultur, kultura łużycka) was one of the most important cultural developments during the Late Bronze and Early Iron Age of central-eastern Europe, 1500–500 bc . In this article, we focus on the …

Ecohydrological Response of a Tropical Peatland to Rainfall Changes Driven by Intertropical Convergence Zone Variability Open
Aim Tropical peatlands are globally significant carbon stores, increasingly threatened by human activities and climate change. However, their ecohydrological responses to shifting water availability remain poorly understood. In this study,…

An Assessment of Palaeoecological and Geochemical Indicators for the Re-establishment of Peat Formation in Ombrotrophic Bogs Open
The restoration of peatlands is becoming an increasingly important topic for both policymakers and the scientific community. However, knowledge on the past succession of ombrotrophic bogs, the extent of disturbance, and their response to c…

Investigating ecological baselines and critical thresholds in ombrotrophic nemoral peatlands: implications for ecological restoration Open
Peatlands are increasingly prone to climate extremes, such as drought, with long-lasting effects on plant and soil communities and, thus, on C cycling. Unveiling past tipping points is a prerequisite for understanding how individual plant …
