Archaea and their interactions with bacteria in a karst ecosystem. [PDF]
Front Microbiol, 2023 Karst ecosystems are widely distributed around the world, accounting for 15–20% of the global land area. However, knowledge on microbial ecology of these systems does not match with their global importance. To close this knowledge gap, we sampled three niches including weathered rock, sediment, and drip water inside the Heshang Cave and three types of ...

Ecosystem service delivery in Karst landscapes: anthropogenic perturbation and recovery [PDF]
Acta Geochimica, 2017 Couvrant de vastes régions de la Chine, les paysages karstiques sont exceptionnels car un changement rapide et intensif de l'utilisation des terres n'a provoqué une grave dégradation de l'écosystème qu'au cours des 50 dernières années. L'intensification de la production alimentaire par l'agriculture au XXe siècle a entraîné une détérioration rapide de ...

Karst ecosystem observation and assessment at local and regional scales [PDF]
InterCarto. InterGIS, 2019 The highly sensitive and vulnerable karst ecosystem in Southwest China is one of the largest exposed carbonate rock areas (more than 0.54 million km2) in the world, hosting 220 million people. Rocky desertification is the most serious eco-environmental problems in China karst.

Village ecosystem vulnerability in karst desertification control: evidence from South China Karst
Frontiers in Ecology and Evolution, 2023 Against the background of global environmental changes and the intensification of human activity, the village ecosystem faces enormous challenges. In particular, the rural areas in South China Karst face serious problems, such as karst desertification and human–land conflicts.

Effects of high Ca and Mg stress on plants water use efficiency in a Karst ecosystem. [PDF]
PeerJ, 2022 BACKGROUND: Karst ecosystems are widely distributed in the world, with one of the largest continuous Karst landforms in Southwest China. Karst regions are characterized by water shortage, high soil calcium (Ca) and magnesium (Mg) content, and soil ...

Carbonate Mineral Dissolution and Its Carbon Sink Effect in Chinese Loess
Land, 2022 The relationship between the source and sink of atmospheric CO2 has always been a widely discussed issue in global climate change research. Recent studies revealed that the chemical weathering of carbonate rocks contributed to 1/3 (~0.5 Pg C/yr) of the ...
