Spatiotemporal Dynamics of NEP and Its Influencing Factors: Exploring the Impact Mechanisms Under Extreme Climate Conditions

Remote Sensing
Current research on net ecosystem productivity (NEP) still lacks sufficient attention to the impacts of extreme climate events, particularly in understanding the interactive response mechanisms of carbon sinks under extreme climate conditions. This study

Driving factors behind multiple populations

Science China Physics, Mechanics & Astronomy
Star clusters were historically considered simple stellar populations, with all stars sharing the same age and initial chemical composition. However, the presence of chemical anomalies in globular clusters (GCs), called multiple stellar populations (MPs), has challenged star formation theories in dense environments.
