Article Synopsis
- Biocrusts are crucial for primary production and nutrient cycling in drylands, yet their role in transferring biologically fixed carbon (C) and nitrogen (N) to mineral soil is not well understood.
- Experimental studies showed that while biocrusts can modulate CO fluxes, drought severely limits their ability to uptake carbon, leading to a decline in net carbon gain.
- Climate change, particularly warming, disrupts the beneficial effects of biocrusts on mineral soil composition and diminishes biological nitrogen fixation, threatening overall soil health and ecosystem functions.
Background And Aims: Clonal growth is widespread among herbaceous plants, and helps them to cope with environmental heterogeneity through resource integration via connecting clonal organs. Such integration is considered to balance heterogeneity by translocation of resources from rich to poor patches. However, such an 'equalization' strategy is only one of several possible strategies.

Material And Methods: We collected incidence, mortality, and gross domestic product (GDP) data between the first quarter of 2020 and of 2023. Then, we reviewed the effectiveness of the mitigation and zero-COVID control strategies.
