Poplar Bark Storage Proteins (BSP) are important in storing nitrogen (N)
recovered from autumn-senescent leaves, and supply N for spring growth. Plants of
Populus tremula x P. alba were transformed with a poplar BSP antisense cDNA
fused to a double 35S promoter. Regenerated lines were screened for reduced BSP
accumulation...
This dissertation re-examines the now standard perceptual model of hillslope
hydrological response to rainfall, which includes the growth of a saturated wedge at the soil-bedrock interface or impeding layer. It also challenges the notion of bedrock impermeability and the assumption that the pattern of subsurface stormflow is determined by the...
We evaluated the regeneration behavior and early growth rates of 10 non-pioneer canopy tree species in medium-height, semi-evergreen dry tropical forest in Quintana Roo, Mexico. These species provide timber and non-timber forest products for local communities and include evergreen and deciduous species with varied dispersal mechanisms. The species were Coccoloba...
