Deployment of sediment traps over a 12-month period has enabled investigation of the lateral variability of overbank deposition rates and particle size composition of deposited sediment across a frequently inundated flood plain section of the River Culm, southeast Devon, UK. Although a general exponential decrease in deposition rate and grain size with distance from the channel occurs, signific...

BACKGROUND AND AIMS In crops other than sugarcane there is good evidence that the size and activity of carbon sinks influence source activity via sugar-related regulation of the enzymes of photosynthesis, an effect that is partly mediated through coarse regulation of gene expression. METHODS In the current study, leaf shading treatments were used to perturb the source-sink balance in 12-month...
