Seepage-induced sand-leakage karst collapse mechanism considering the soil arching effect

Shuiwen dizhi gongcheng dizhi
Sand-leakage karst collapse often occurs in the hidden karst area of the binary structure covering layer due to seepage. However, further research is needed to understand the macro and micro mechanical mechanisms of such collapse and the mechanical ...

Ostracode-based aminostratigraphy and aminochronology of a tufa system in central Spain [PDF]

, 2005
In the Priego area, central Spain, extensive tufa deposits are located in three small tributaries located at the head of the 1000 kmlong Tagus River. The deposits are originated after karst-origin running waters emerged from the confines of the canyons ...

Simulating N2O Emissions From Inland Waters: Model Development and Site‐Level Study

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Inland waters are significant sources of atmospheric nitrous oxide (N2O), and their emissions are expected to rise rapidly due to human activities. However, current estimates remain highly uncertain, partly because sparse field measurements and existing models fail to capture fine‐scale variations in N2O emissions, especially due to the ...

Numerical simulation of critical flow velocity in the covered karst soil cave formation

Shuiwen dizhi gongcheng dizhi
The covered karst collapse has the characteristics of concealment, suddenness, uncertainty, and mechanism complexity, which leads to its prevention and treatment more difficult. In the process of covered karst collapse, soil caves formed in the overlying

Reduced snow cover at the alpine treeline: resistance and recovery of saplings

New Phytologist, Volume 250, Issue 3, Page 1492-1509, May 2026.
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Equipped for success: genomes and metabolomes of the European Amanita muscaria are conserved in its novel South African range

New Phytologist, Volume 250, Issue 3, Page 1863-1883, May 2026.
Summary Plants and soils have been moved around the world for centuries, but invasive mushrooms receive scant attention. The Amanita muscaria species complex was introduced to South Africa in the context of forestry, but its origins, ecology and recent evolution are unstudied. We sequenced the genomes of 24 Northern and Southern Hemisphere A. muscaria,

Evaporite sinkholes of the Friuli Venezia Giulia region (NE Italy) [PDF]

, 1991
Sinkholes are common in the Friuli Venezia Giulia (FVG) Region (NE Italy), where the presence of karstifiable rocks favours their occurrence accelerated by intense rainfalls.
