Climate and human impacts inferred from a 1500-year multi-proxy record of an alpine peatland in the South-Eastern Alps

open access: yesEcological Indicators, 2022
In the last decades, climate and human activities significantly affected ecosystems, particularly in mountain areas. Whereas the Alps have been extensively studied for palaeoclimatic reconstructions, little information is available about ecological ...

Dominant influence of non-thawing periods on annual CO2 emissions from Zoige peatlands: Five-year eddy covariance analysis

open access: yesEcological Indicators, 2021
Changes in freeze–thaw processes as a result of climate change significantly affect the carbon balance of terrestrial ecosystems, especially peatlands.

Subsidence in Qinghai—Tibet Plateau Peatlands Driven by Drainage Disturbance and Climatic Variability

open access: yesGeosciences
Peatlands are globally important carbon sinks, yet these are increasingly threatened by climate change and human disturbances. Among degradation indicators, surface subsidence is gradual and challenging to monitor, particularly in alpine peatlands.

Relation between methanogenic archaea and methane production potential in selected natural wetland ecosystems across China [PDF]

open access: yesBiogeosciences, 2011
Methane (CH<sub>4</sub>) emissions from natural wetland ecosystems exhibit large spatial variability at regional, national, and global levels related to temperature, water table, plant type and methanogenic archaea etc.

Maximising trait evenness promotes the recovery of plant species richness in managed grasslands

open access: yesEcography, EarlyView.
Land‐use intensification threatens biodiversity, and restoring degraded ecosystems remains challenging due to the difficulty of identifying the rules governing community assembly and dynamics. Investigating the temporal dynamics of trait‐abundance distributions (TADs) along long‐term time series offers a promising approach to disentangle the influence ...

Multidimensional diversity of bird communities across spatial variation of land cover in Zoige on the eastern Qinghai-Tibetan Plateau

open access: yesAvian Research, 2021
Background Spatial variation of land cover can result in the changes of community similarities and biotic homogenization, whereby the increasing similarity would reduce the adaptive capacity of biotic assemblages to further disturbance, and degenerate ...

Water Table Decline Shifts Microbial Necromass From Particulate to Mineral‐Associated Pools in Peatlands

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Microbial necromass carbon (MNC) is a major and stable component of soil organic carbon, yet its fraction‐specific accumulation and stabilization mechanisms remain unclear, particularly in peatlands experiencing hydrological change. We investigated MNC distribution along three independent transects spanning a natural gradient of five ...

Internal Permafrost Structure of Geomorphologically Distinct Palsas in Northern Sweden Revealed by Quasi‐3D ERT

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Incorporating burn probability into spatial prioritization of woodland caribou habitat restoration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Habitat disturbance is a major driver of population declines of woodland caribou in Canada. Habitat restoration is a critical component of a successful, long‐term approach to caribou recovery; however, with limited resources, it is important to target areas where restoration efforts will provide maximum benefits to caribou.
