Wetland succession in a permafrost collapse: interactions between fire and thermokarst [PDF]

open access: yes, 2007
To determine the influence of fire and thermokarst in a boreal landscape, we investigated peat cores within and adjacent to a permafrost collapse feature on the Tanana River Floodplain of Interior Alaska.

Using high‐resolution imagery to map Scots pine regeneration in the Scottish uplands

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
This study utilizes high‐resolution imagery to map over 90,000 naturally regenerating Scots pines across a 3360‐ha area in the Scottish Uplands. Our approach demonstrates that remote sensing can accurately quantify landscape‐scale forest expansion, identifying nearly 85% of saplings over 2 m tall.

Investigating the ecological consequences of historic forest drainage through vegetation composition across Sweden

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract For hundreds of years, humans have drained water from landscapes, especially peatlands, to improve agriculture and forestry. Widespread, intensive ditching alters ecosystem processes and vegetation communities in ways that may last decades after ditch abandonment and that could be irreversible or require extensive intervention to reverse ...

Towards Affordable Wetland Evapotranspiration Monitoring Using the Variance‐Bowen Ratio Method: Insights From Three Contrasting Wetlands

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract Accurate measurement of evapotranspiration (ET) is essential for sustainable water management. Standard methods such as eddy covariance (EC) are costly, while alternatives such as surface renewal are cheaper but require calibration and complex data processing.

Decoupling of alpine wetland degradation and regional development

open access: yesEcological Indicators
Wetland is the core functional system of the global alpine region. However, with the development of the social economy in the past few decades, the alpine wetland ecosystem has suffered serious shrinkage, drying, degradation and landscape fragmentation ...

Longer thaw seasons increase nitrogen availability for leaching during fall in tundra soils [PDF]

open access: yes, 2016
Climate change has resulted in warmer soil temperatures, earlier spring thaw and later fall freeze-up, resulting in warmer soil temperatures and thawing of permafrost in tundra regions.

Limited release of previously-frozen C and increased new peat formation after thaw in permafrost peatlands [PDF]

open access: yes, 2017
Permafrost stores globally significant amounts of carbon (C) which may start to decompose and be released to the atmosphere in form of carbon dioxide (CO 2 ) and methane (CH 4 ) as global warming promotes extensive thaw.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Century‐long trends in plant diversity of temperate mountain vegetation are modulated along elevation gradient

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.

UAV Photogrammetry-Based Leaf Area Index for Above-Ground Biomass Estimation in Wetlands

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Wetlands are highly productive and biologically diverse environments that provide numerous ecosystem services. Effective monitoring methods are critical to ensure their preservation and management.
