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.

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 ...

Measuring plant canopy structure
Remote Sensing of Environment, 1985The potential of three systems to quantify plant canopy structure, key input data to canopy reflectance models is examined. The results show an optical radar system is potentially capable of providing the most fundamental type of structural data, the area, and the direction of the normal of each small piece of foliage in each cube of space in the ...

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.

Structural Assessment of Rapid Deployment Canopy Structure
Advances in Structural Engineering, 2006A lightweight, deployable canopy system has been designed to provide weather protection for events seating. Built as a cantilever truss fixed to the back of seating systems, the canopy avoids the use of columns within the viewing area and is deployed from the ground level.

Canopy Architecture and Turbulence Structure in a Coniferous Forest
Boundary-Layer Meteorology, 2003Synchronous sonic anemometric measurements at five heightswithin a mixed coniferous forest were used to test two different parameterisations ofcanopy architecture in the application of a second-order turbulence closure model. Inthe computation of the leaf drag area, the aerodynamic sheltering was replaced with anarchitectural sheltering, assumed to be ...

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.

Modeling canopy structure and heterogeneity across scales: From crowns to canopy
Forest Ecology and Management, 1997Abstract Canopy studies have been limited in ecological investigations due to problems of canopy accessibility, and the lack of efficient sampling and modeling methods. The primary objective of this study was to develop an efficient modeling approach to describe the 3-dimensional, hierarchical structure of individual crown shells within stands and ...

Forest Canopy Structural Properties
2008The forest canopy is the interface between the land and the atmosphere, fixing atmospheric carbon into biomass and releasing oxygen and water. The arrangement of individual trees, differences in species morphology, the availability of light and soil nutrients, and many other factors determine canopy structure.
