Chalcone Isomerase a Key Enzyme for Anthocyanin Biosynthesis in Ophiorrhiza japonica

open access: yesFrontiers in Plant Science, 2019
Anthocyanins are distributed ubiquitously to terrestrial plants and chalcone isomerase (CHI) catalyzes the stereospecific isomerization of chalcones – a committed step in the anthocyanin biosynthesis pathway.

Asymmetric Responses of Ecosystem Health to Urbanization in a Typical Karst City: Spatiotemporal Patterns and Driving Mechanisms in Guilin, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Urban expansion can substantially reshape ecosystem structure and functioning, especially in ecologically fragile Karst landscapes. Clarifying how ecosystem health (EH) responds to urbanization and identifying the factors that drive spatial variation in EH are important for regional sustainability.

Estimation Accuracy Obviously Increased of Soil Organic Carbon Content Based on Habitat Patches Scale Using Interpretable Machine Learning in Southwest China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Although machine learning models have been successfully applied to estimate soil organic carbon (SOC), the lack of interpretability research has resulted in the absence of mechanistic explanations for these models. Therefore, in this study, we adopted the following workflow: first, we divided the whole study area into several subregions using ...

Exploring Relationships Between Karst Terrains and Social Features by the Example of Gömör-Torna Karst (Hungary-Slovakia) [PDF]

open access: yes, 2015
Human-environment relations have some special characteristics on karst terrains, and karstlands are usually less densely inhabited areas principally due to hydrologic, topographic and pedologic reasons.

Spatiotemporal Interactions of Land Use Change, Land Surface Temperature, and Vegetation Dynamics in China's Caohai National Nature Reserve

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Understanding the spatiotemporal dynamics of land use change (LUC), land surface temperature (LST), and vegetation indices is critical for assessing ecological changes and informing sustainable land management. This study investigates the long‐term interrelationships between LUC, LST, and vegetation indices in China's Caohai National Nature ...

Recent Advances for Phase Transformation and Reconstruction of Gold-bearing Inclusions during the Pre-oxidation of Refractory Gold Ores

open access: yesKuangchan zonghe liyong
This is an article in the field of mining engineering. Under the background of "double carbon" and "ballast stone" of refractory gold ore resources, pre-oxidation is an effective pretreatment method for efficient gold extraction from refractory gold ores.

Seasonal Dynamics of Soil Multitrophic Biodiversity, Co‐Occurrence Network and Assembly Mechanisms Under Typical Vegetation Restoration Patterns in Karst Region

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Previous studies often overlooked the dynamic effects of karst vegetation restoration on soil multi‐trophic biodiversity and the underlying community‐assembly mechanisms. To fill this gap, we performed a seasonal comparative analysis of soil biodiversity, co‐occurrence network architecture, and assembly processes across three representative ...
