Land Degradation &Development, EarlyView.ABSTRACT Cereal‐legume rotation is regarded as an important agricultural management strategy for enhancing soil organic carbon (SOC) and improving soil ecosystem multifunctionality (EMF). The soil microbial carbon pump (MCP) exerts a regulatory effect on the production of microbial necromass as well as the SOC accumulation.

Bacillus subtilis Mobilizes Phosphorus by Reshaping P Pools, Sorption, and Enzyme Activities
Land Degradation &Development, EarlyView.ABSTRACT Low phosphorus (P) availability constrains crop production in saline‐alkaline soils of Xinjiang, China. We tested whether Bacillus subtilis (B. subtilis) mobilizes soil P by altering P fractions, sorption–desorption, and P‐cycling enzymes in a saline‐alkaline cotton soil. Under conventional fertilization, B. subtilis was applied at 0 (B0), 15 (

Land Degradation &Development, EarlyView.ABSTRACT Lateral carbon transport induced by soil erosion is a key component of the global carbon cycle. Over the past 50 years, ecological restoration projects in the Loess Plateau of China have increased vegetation coverage. However, the effects of land use, precipitation variability, and landscape factors on lateral carbon transport remain unclear ...

Moss Biocrusts Regulate Heavy Metal Speciation and Mobility in Coal Mine Soils
Land Degradation &Development, EarlyView.ABSTRACT On a global scale, coal mining activities often lead to heavy metal(loid) contamination in soils of mine dump sites, posing serious ecological risks. As ecosystem “engineers,” biological soil crusts (biocrusts)—especially moss crust—have shown great potential in remediating heavy metal‐polluted soils, but their roles remain underexplored.

Greed, Grievance, and Mobilization in Civil Wars
Journal of Conflict Resolution, 2005Greed, grievances, and mobilization are generally offered as explanations for rebellion and civilwar. The authors extend arguments about the precursors to nonviolent protest, violent rebellion, and civil war. These arguments motivate a series of hypotheses that are tested against data from the Minorities at Risk project.

MOBILE MEDICAL SUPPORT FOR CIVIL DEFENSE
Journal of the American Medical Association, 1956• Help for survivors in a nuclear blast area must come from the periphery. Consequently it depends on organized mobile groups from the surrounding region. Such a unit, planned to include first aid for 250 casualties, was given a field trial in "Operation Mercy." Four hospitals willingly agreed to supply equipment for the four operating teams, three ...
