People and Nature, EarlyView.Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Processes affecting the transformation of riverine dissolved organic carbon (DOC) across the land‐to‐ocean aquatic continuum are still poorly constrained in Arctic models, leading to large uncertainties in simulated air–sea CO2 fluxes of the coastal periphery.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Differential frost heave between fine (earthy) and coarse (gravelly) domains was monitored over 10 years (2013–2023) on a mountain‐top flat ground subjected to both frequent diurnal and deep seasonal freezing. Monitoring objects include, ground heave, soil temperature down to 55 cm, soil moisture, air temperature, rainfall, and snow depth. The

Active Layer Warming and Thickening on CALM‐S JGM, James Ross Island, in the Period 2013/14–2022/23
Permafrost and Periglacial Processes, EarlyView.ABSTRACT The Circumpolar Active Layer Monitoring‐South (CALM‐S) site was established near the Johann Gregor Mendel (JGM) research station on James Ross Island in February 2014. The CALM‐S JGM grid, measuring 80 × 70 m, encompasses two distinct lithological units: a Holocene marine terrace (covering approximately 75% of the grid) and Cretaceous ...
