Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes

New Phytologist, Volume 252, Issue 1, Page 54-68, October 2026.
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

Spatial and temporal evolution of a coastal erg margin: The Middle Jurassic Page Sandstone, southern Utah, USA

Sedimentology, Volume 73, Issue 6, Page 2081-2119, October 2026.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Evaluation of Cherts in Gumushane Province in Terms of Alkali Silica Reaction

Buildings
Alkali–silica reaction (ASR) occurs when alkali oxides coming from the cement composition in concrete come together with reactive silica and moisture coming from the aggregate.

Diagenetic evolution of porosity microfabric in biosiliceous sediments, Monterey Formation, California, United States

Frontiers in Earth Science
Biosiliceous sediments have a unique diagenesis with abrupt transformations in porosity, density, sonic velocity and rock strength. With time or increased temperature, biosiliceous sediments undergo two transitions in silica phase.
