Biomass-modulated fire dynamics during the last glacial-interglacial transition at the central pyrenees (Spain) [PDF]

, 2014
Understanding long-term fire ecology is essential for current day interpretation of ecosystem fire responses. However palaeoecology of fire is still poorly understood, especially at high-altitude mountain environments, despite the fact that these are ...

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

Geosciences
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.

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

, 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.

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

Avian 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 ...

Floristic variation in Sphagnum-dominated peatland communities of the Central Highlands, Victoria [PDF]

, 2013
The floristic composition of Sphagnum-dominated peatlands in the Central Highlands region of Victoria was surveyed (37º 25´ S; 145º 50´ E). NMDS ordination and cluster analysis divided the peatland sites into two broad groups with altitude being the most

Integrating ecological feedbacks across scales and levels of organization

Ecography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Molecular mechanisms of water table lowering and nitrogen deposition in affecting greenhouse gas emissions from a Tibetan alpine wetland. [PDF]

, 2017
Rapid climate change and intensified human activities have resulted in water table lowering (WTL) and enhanced nitrogen (N) deposition in Tibetan alpine wetlands.

Reduced Carbon Dioxide Sink and Methane Source under Extreme Drought Condition in an Alpine Peatland [PDF]

Sustainability, 2018
Potential changes in both the intensity and frequency of extreme drought events are vital aspects of regional climate change that can alter the distribution and dynamics of water availability and subsequently affect carbon cycles at the ecosystem level.

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

Reviews 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,

Use of Microbial Biofilms to Assess Groundwater Quality in Karstic Ecosystems

Environmental Microbiology, Volume 28, Issue 2, February 2026.
Analyses of prokaryotic diversity and community structures of biofilms showed variations linked to the nutrient and organic matter conditions in the studied karstic stations. Biofilms developed on artificial substrates appeared as promising indicators to assess groundwater quality in karst.
