Disentangling gross N2O production and consumption in soil
The difficulty of measuring gross N2O production and consumption in soil impedes our ability to predict N2O dynamics across the soil-atmosphere interface. Our study aimed to disentangle these processes by comparing measurements from gas-flow soil core (GFSC) and 15N2O pool dilution (15N2OPD) methods. GFSC directly measures soil N2O and N2 fluxes, with their sum as the gross N2O production, wher...
متن کاملSalt Marsh Claviceps purpurea in Native and Invaded Spartina Marshes in Northern California
Epidemics caused by plant-pathogenic fungi are relatively rare in wild plant populations (7). Relatively constant, low disease incidence is expected in natural plant populations because environmental heterogeneity, species richness (26,30), host density (8), genetic diversity (2,37), age structure (11), and host–pathogen coevolution (36) each militate against range-wide epidemics. However, plan...
متن کاملEnvironmental and biological controls on methyl halide emissions from southern California coastal salt marshes
Methyl bromide (CH3Br) and methyl chloride (CH3Cl) emission rates from southern California coastal salt marshes show large spatial and temporal variabilities that are strongly linked to biological and environmental factors. Here we discuss biogeochemical lines of evidence pointing to vegetation as the primary source of CH3Br and CH3Cl emissions from salt marshes. Sediments and macroalgae do not...
