Overview on karst geology of Vietnam

open access: yesCarsologica Sinica
Karst is widely distributed in Vietnam, covering almost 60,000 km2, approximately 20% of the total area of Vietnam. Most karst rocks crop out in North and Central Vietnam. Karst developed with peak-clusters, peak-forests, caves, etc.

Karst [poster] [PDF]

open access: yes, 2005
Florida’s geology allows for the creation of many interesting features including sinkholes, underground rivers, springs, and caves. These features make up what is called karst topography which forms as flowing water slowly dissolves the limestone and ...

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

open access: yesNew Phytologist, EarlyView.
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

Spatiotemporal evolution of landscape stability in World Heritage Karst Sites: a case study of Shibing Karst and Libo-Huanjiang Karst

open access: yesHeritage Science
Landscape stability is a paramount concern within the field of landscape ecology. Indices of landscape patterns not only facilitate an effective analysis of land use transformations but also delve into the mechanisms of landscape disturbances across ...

Dissolution process of carbonate rocks by different types of water in atmospheric environment and δ13C evolution of dissolved inorganic carbon

open access: yesCarsologica Sinica
Carbonate dissolution is a geological process that occurs in the shallow surface environment of the Earth. Due to its geochemical characteristics—such as low temperature, openness, sensitivity, and biological participation—it leads to variability in the ...

Preliminary hydrogeological characterization of an evaporite karst area (province of Cordoba, South Spain) [PDF]

open access: yes, 2015
The northern sector of the Subbetic Domain in the Betic Cordillera is formed by an olistostrome unit known as the Chaotic Subbetic Complex (CSC). This megabreccia is basically made of Triassic (Keuper) clays and evaporites (gypsum, anhidrite and halite)

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

open access: yesNew Phytologist, EarlyView.
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,

The initial stages of cave formation: Beyond the one-dimensional paradigm

open access: yes, 2010
The solutional origin of limestone caves was recognized over a century ago, but the short penetration length of an undersaturated solution made it seem impossible for long conduits to develop.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Occurrence of 'Antrobathynella stammeri' (Jakobi, 1954) (Crustacea: Syncarida: Bathynellidae) in the hyporheic zones of two English karst rivers [PDF]

open access: yes, 2008
This paper reports the first records of Antrobathynella stammeri in the British Isles since 1985. Numerous individuals were observed in hyporheic water extracted from the River Skirfare (Yorkshire, UK), whilst, in an independent study, a single confirmed
