Canopy Structure and Environmental Interactions
1979patterns of vegetation have generally been recognized first on the basis of physiognomy, i.e., the structure of the vegetation canopy, and second by species composition. Several investigations have sought general relationships between physiognomy and climate; others have correlated physiognomy with soil properties.

Turbulent Structures in Canopy Flows
2014A wind-tunnel experiment has been performed by means of a new forest canopy model. Hot-wire anemometry and Particle Image Velocimetry have been used to describe the flow from the statistical point of view together with a conditional sampling approach based on the Variable Interval Time Average method.

Turbulence structure above a vegetation canopy
Journal of Fluid Mechanics, 2009We compare the turbulence statistics of the canopy/roughness sublayer (RSL) and the inertial sublayer (ISL) above. In the RSL the turbulence is more coherent and more efficient at transporting momentum and scalars and in most ways resembles a turbulent mixing layer rather than a boundary layer.

Canopy Structure of the Forest
2003In order to assess herbivory rates (see Chap. 11) and also to calculate the effect of foliage removal on canopy carbon and water relations (see Chaps. 12 and 14), it is necessary to gain sufficient information on the amount of foliage present and its arrangement in space.

Diurnal variations of vegetation canopy structure
International Journal of Remote Sensing, 1983The significance and magnitude of diurnal variations of vegetation canopy structure are reviewed. Diurnal leaf inclination-azimuth angle distributions of a soybean and cotton canopy were documented using a simple measurement technique. The precision of the measurements was on the order of + or -5 deg for the inclination and + or -14 deg for the azimuth.

Structure of Foliage Canopies and Photosynthesis
Annual Review of Ecology and Systematics, 1973All living things on the earth, including plants, rely principally upon the photosynthate produced by plants for their daily food, and accordingly are strongly affected by the variation of plant photosynthesis over the globe. The distribution of solar energy with latitude determines to a great extent the geographic variation of photosynthetic activity ...

Forest canopy-structure characterization: A data-driven approach
Forest Ecology and Management, 2015Forest canopy structure influences and partitions the energy fluxes between the atmosphere and vegetation. It serves as an indicator of a variety of biophysical variables and ecosystem goods and services. Airborne laser scanning (ALS) can simultaneously provide horizontal and vertical information on canopy structure.

Functional significance of variation in bryophyte canopy structure
American Journal of Botany, 2001In most bryophytes, the thickness of boundary layers (i.e., unstirred layers) that surrounds plant surfaces governs rates of water loss. Architectural features of canopies that influence boundary layer thickness affect the water balance of bryophytes.
