Artificial wetlands, also known as constructed wetlands, are engineered systems designed to mimic the functions of natural wetlands for purposes such as water treatment, flood control, and habitat restoration. They leverage natural processes involving wetland vegetation, soils, and microbial life to purif...

For scenes with vegetation (Nogueiró, Levada, Sameiro) mean relative deviations were somewhat smaller for S cones than for L and M cones, and for each scene the effects of point spacing were similar. But over scenes, the mean relative deviation for a given spacing varied by a factor of...
Natural hazards have the potential to cause catastrophic damage and significant socioeconomic loss. The actual damage and loss observed in the recent decad
Plant extraction requires substantial amounts of plant raw materials, posing the risk of vegetation destruction. In addition, the intricate structure of PNPs, often containing multiple chiral carbon atoms, results in a relatively low selective yield for chemical synthesis. In response to these ...
Fundamental natural elements such as elevation, slope, aspect, and soil types can significantly affect the evapotranspiration and water use efficiency of vegetation, thereby affecting vegetation growth [11,12]. Temperature and precipitation are considered the most important climatic factors that affect ...
The highest content of caffeic acid was found at the beginning of plant vegetation, while apigenin was found at full flowering and the beginning of seed setting. Bencsik et al. [108] showed that the total flavonoid content of the Lythrum salicaria L. herb was higher at full flowering (...
Known as 'maar' craters, these bodies reveal a nearly uninterrupted stack of sediments dating back to 150,000 years ago that provides data for the reconstruction of past climate, vegetation and ecology. Similarly, fossils found in 43 million years old sediments of Eckfeld Maar are of worldwide...
, deforestation, lack of crop rotation, improper surface drainage, monoculture and excessive use of fertilizers, etc. soil erosion drastically affects soil fertility and renders it useless. in extreme cases, it may leave patches of land dry and increasingly arid, losing its wildlife and vegetation ...
