Desertification in karst areas: A review

Earth-Science Reviews
Desertification in karst is an effect of climate change and not sustainable anthropogenic activities, the combination of which, however, causes the gradual loss of karst natural resources, such as soil, vegetation, and groundwater. A considerable percentage of global karst areas is found in drylands, characterized by negative water balance and scarce ...

Chalcone-Synthase-Encoding RdCHS1 Is Involved in Flavonoid Biosynthesis in Rhododendron delavayi

Molecules
Flower color is an important ornamental feature that is often modulated by the contents of flavonoids. Chalcone synthase is the first key enzyme in the biosynthesis of flavonoids, but little is known about the role of R.

Subsurface flow aggravates the soil erosion on steep slopes in karst post-mining areas

Journal of Hydrology: Regional Studies
On karst steep slopes, subsurface flow frequently emerges at the rock-soil interface, thereby exacerbating soil erosion. However, there have been few studies that quantitatively assess the impact of subsurface flow on soil erosion in this region.

Overview of karst geology in Turkey

Carsologica Sinica
Turkey is distributed with karst up to about 40% of its land area, in which karst is developed under typical Mediterranean climate. According to the structural characteristics, Turkey is divided into four different karst areas from north to south, among ...
