Aims Elevated atmospheric CO 2 can impact soil organic carbon (SOC) cycling through increased photosynthetic carbon allocation in the rhizosphere, accelerating the decomposition of SOC (rhizosphere priming). How elevated CO 2 modifies priming intensity in different soil types and the associated microbial functional pathways remains poorly understood. Methods Using dual 13 C/ 15 N labelling, this study compared rhizosphere prim...

Background and aims Water scarcity due to increasing climate variability means improved drought tolerance in crop plants is more urgent. Addition of organic wastes could enhance crop drought tolerance through improved nutrition or increased soil water holding capacity. However, their effect on crop water relations, mediated by plant beneficial soil microbes, remains less well-studied. This study aims to understand how applicat...

The seed bank of Halophila ovalis is crucial for resilience to disturbance through re-establishment. Understanding seasonal changes in abundance and quality of seeds in natural seed banks is critical for seed-based restoration. We selected an estuary in southwestern Australia and investigated the seasonal changes of seed distribution and viability in H. ovalis seed banks. We also adapted an X-ray viability test used for terres...
