Mesoscale eddies heterogeneously modulate CO₂ fluxes in eddy-rich regions of the Southern Ocean [PDF]

Biogeosciences
Mesoscale eddies are known to influence the Southern Ocean biogeochemistry. However, the distinct contributions of cyclonic and anticyclonic eddies to air–sea CO2 fluxes, as well as their longer-term effects remain poorly studied. We present results from

National forest carbon harvesting and allocation dataset for the period 2003 to 2018 [PDF]

Earth System Science Data
Forest harvesting is one of the anthropogenic activities that most significantly affect the carbon budget of forests. However, the absence of explicit spatial information on harvested carbon poses a huge challenge in assessing forest-harvesting impacts ...

Spatiotemporal Response and Driving Factors of Carbon Stocks to Land Use Change in Southwest China Karst Region

Ecosystem Health and Sustainability
Karst landscapes serve as vital carbon reservoirs, yet the long-term dynamics of their multiple carbon pools and the underlying driving mechanisms remain insufficiently understood.

Integrated modeling of blue and green water evolution in a headwater region of Chaohu Lake: Impacts of climate and surface environmental factors

Ecological Indicators
Understanding the dynamic changes of blue water (BW, surface and groundwater) and green water (GW, soil-stored rainfall used by plants via evapotranspiration) is essential for assessing water resource sustainability.

The global terrestrial carbon cycle

Water, Air, & Soil Pollution, 1993
There is great uncertainty with regard to the future role of the terrestrial biosphere in the global carbon cycle. The uncertainty arises from both an inadequate understanding of current pools and fluxes as well as the potential effects of rising atmospheric concentrations of CO2 on natural ecosystems.

Integrated geochemical and geophysical assessment for monitoring soil stabilization with waste oyster shells

Scientific Reports
We assessed the field-scale stabilization efficiency of lead (Pb) and copper (Cu) in contaminated soils using powdered (WOS-P) and granular (WOS-G) waste oyster shell (WOS) amendments.

Variabilities of dissolved inorganic carbon along chain-shaped karst river-reservoir continuum: The control of cascade damming

Journal of Hydrology: Regional Studies
Study Region: The natural river, reservoir profiles, and inflow/outflow waters of ten cascade reservoirs along the Xijiang River in the subtropical karst region of southern China were studied.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Spatio-temporal dynamics and drivers of drying conditions in the HRB: Unraveling the role of precipitation intensity and total precipitation in drying risk

Journal of Hydrology: Regional Studies
Study region: The Hangbu River Basin (HRB), located in eastern China, is the largest sub-basin of the Chaohu Lake Basin. Study focus: In recent decades, the HRB has experienced increased drying and spatial heterogeneity in its hydrological conditions ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
