Soil temperature plays an important role in soil respiration, which is related to the atmospheric carbon cycle. In addition its own physical and chemical properties, also influenced by external environmental factors, including plants. Therefore, it relevant explore relationship between plant characteristics temperature. This study was conducted Hangzhou, China. The influence of canopy structura...

re-vegetation of bare soil is believed to increase, or at least maintain the organic matter levels of soil. the aim of this study was to investigate the soil characteristics changes, nutrient pool sizes and their availability under mid canopy, and canopy gap positions of saltbush in an area re-vegetated with atriplex lentiformis. some of the physical and chemical soil characteristics (the parti...

1. The functional characteristics of forests are related to the organization of their canopies. However, understanding the relationship between canopy structure and function has been limited by a paucity of methods for determining structure at scales consistent with those of function measurements. 2. We describe here a portable system, assembled from commercially available components, for acqui...

Satellite-based estimates of vegetation structure capture broad-scale vegetation characteristics as well as differences in vegetation structure at plot-scales. Active remote sensing from laser altimetry and radar systems is regularly used to measure vegetation height and infer vegetation structural attributes, however, the current uncertainty of their spaceborne measurements is likely to mask a...

Computational fluid dynamic studies of 3-D, fixed geometry, gore-shaped parachute canopies are presented. Both solid and ribbon canopies with a 10% vent diameter are investigated. The flowfields analyzed are laminar and compressible, broaching both the subsonic and supersonic regimes. Results presented include characterization of the local and global flowfields and the internal and external can...

Fresh pistachio fruit cv. Kalleghochi was harvested from the exterior and interior parts of the tree canopy in four geographical directions. The fruit position in exterior and interior parts of the tree canopy has a significant influence on the number of nuts per ounce, pistachio splitting, hull weight, shell weight, kernel weight, colour indices and total anthocyanin content. Results indicated...

Title of Document: ENHANCEMENT OF A CANOPY REFLECTANCE MODEL FOR UNDERSTANDING THE SPECULAR AND SPECTRAL EFFECTS OF AN AQUATIC BACKGROUND IN AN INUNDATED TIDAL MARSH Kevin Ross Turpie, Ph.D., 2012 Directed By: Professor Michael Kearney, Department of Geographical Sciences The presence of water produces unique specular and spectral characteristics in an inundated tidal marsh canopy. The aquatic ...

In this study, the early development of monocultures and mixtures of Cedrela odorata, Cordia alliodora, and Hyeronima alchorneoides was measured to determine what interspecific differences in structural characteristics lead to good ecological Ž . combining ability in fast-growing tropical tree species. Plantations were established at high density 2887 treesrha on fertile alluvial soil in the hu...
