Boundary-layer flow within and above a forest canopy of variable density

, 2012
An analytical model is developed for flow within and above a forest canopy with a slowly varying canopy density. Results are compared with existing analytical models for flow over a surface with slowly varying roughness length, and also with numerical ...

Comparative Transcriptome-Based Analysis of the Regulation of Leaf Senescence in the Upper and Middle Canopy of Different Soybean Cultivars

Agronomy
Premature leaf failure is one of the major factors contributing to crop yield reduction. High-yielding soybean cultivars exhibit a longer leaf lifespan during the reproductive period, promoting higher yields. In this experiment, physiological indexes and

Remote sensing investigations of wetland biomass and productivity for global biosystems research [PDF]

The relationship between spectral radiance and plant canopy biomass was studied in wetlands. Spectroradiometer data was gathered on Thematic Mapper wavebands 3, 4, and 5, and correlated with canopy and edaphic factors determined by harvesting.
