Damage in porous media due to salt crystallization [PDF]

, 2010
We investigate the origins of salt damage in sandstones for the two most common salts: sodium chloride and sulfate. The results show that the observed difference in damage between the two salts is directly related to the kinetics of crystallization and ...

How do drying and rewetting events affect nutrient fluxes and bacteria dynamics in subtropical estuarine sediments? [PDF]

, 2018
Drying and rewetting occur frequently in coastal marsh sediments due to oscillations of rising and falling tides, and episodic droughts and floods. Similarly, drying events also occur within freshwater systems due to changing precipitation patterns ...

Absence of oxygen effect on microbial structure and methane production during drying and rewetting events

Scientific Reports, 2022
Natural environments with frequent drainage experience drying and rewetting events that impose fluctuations in water availability and oxygen exposure. These relatively dramatic cycles profoundly impact microbial activity in the environment and subsequent

Asynchronous pulse responses of soil carbon and nitrogen mineralization to rewetting events at a short-term: Regulation by microbes

Scientific Reports, 2017
Rewetting after precipitation events plays an important role in regulating soil carbon (C) and nitrogen (N) turnover processes in arid and semiarid ecosystems.

The effect of desiccation on the emission of volatile bromocarbons from two common temperate macroalgae [PDF]

, 2014
Exposure of intertidal macroalgae during low tide has been linked to the emission of a variety of atmospherically-important trace gases into the coastal atmosphere.

Artificial weathering pools of calcium-rich industrial waste for CO2 sequestration [PDF]

, 2011
Processes of carbonation of calcium-rich aqueous industrial wastes from acetylene production were performed mimicking rock weathering, using the atmospheric carbon dioxide as reactant.

Estimating taxon‐specific population dynamics in diverse microbial communities

Ecosphere, 2018
Understanding how population‐level dynamics contribute to ecosystem‐level processes is a primary focus of ecological research and has led to important breakthroughs in the ecology of macroscopic organisms.

Impact of drying, freezing and re-wetting events soil leachate in acidic versus calcareous soils [PDF]

Journal of the Serbian Chemical Society
This study investigates the impact of drying-rewetting and freezing-rewetting events on soil leachate ion composition across two contrasting geochemical settings through a series of controlled laboratory experiments.

Sediment drying-rewetting cycles enhance greenhouse gas emissions, nutrient and trace element release, and promote water cytogenotoxicity.

PLoS ONE, 2020
Increased periods of prolonged droughts followed by severe precipitation events are expected throughout South America due to climate change. Freshwater sediments are especially sensitive to these changing climate conditions.

The Response of Microbial Communities to Peatland Drainage and Rewetting. A Review

Frontiers in Microbiology, 2020
Peatlands are significant global carbon stores and play an important role in mediating the flux of greenhouse gasses into the atmosphere. During the 20th century substantial areas of northern peatlands were drained to repurpose the land for industrial or
