There is increasing attention on the effects of seasonal snowpack on wintertime litter decomposition, as well as the processes following it, in cold biomes. However, little information is available on how litter nitrogen (N) dynamics vary with snowpack variations created by tree crown canopies in alpine forests. Therefore, to understand the effects of seasonal snowpack on litter N dynamics duri...

Soil moisture is an important yet unobserved reservoir of the hydrologic cycle linked to the spatial and temporal variability of precipitation [1]. The brightness temperature of the land surface at microwave wavelengths is sensitive to soil moisture. Terrestrial brightness temperature also depends on the temperature of the soil and vegetation canopy as well as other canopy and soil properties [...

Improved understanding of the links between aboveground production and allocation of photosynthate to belowground processes and the temporal variation in those links is needed to interpret observations of belowground carbon cycling processes. Here, we show that combining a trenching manipulation with high-frequency soil respiration measurements in a temperate hardwood forest permitted identific...

intercropping is a correct method of management for crop production and leads to improvement of resource absorption and use by plants. in order to evaluate light interception and some characteristics of canopy in monocropping and intercropping of maize (zea mays l.) and faba bean (vicia faba l.) under climatic conditions of tabriz, a field experiment was conducted in 2006-2007 at the research s...

We measured growth and development variables on single soybean [Glycin max (L.) Merr.] plants under five management strategies in the upper Midwestern USA. Plants grown under different management strategies differed significantly in their geometric structures, and were classified into their proper categories with 75 to 100% correct classification, based mainly on differences in their fractal di...

In this paper, we discuss the impact of a rain forest canopy on the statistical characteristics of atmospheric turbulence. This issue is of particular interest for understanding on how the Amazon terrestrial biosphere interact with the atmosphere. For this, we used a probability density function model of velocity and temperature differences based on Tsallis’ non-extensive thermostatistics. We c...

There is a strong need to extend whole-tree measurements of sap flow into broad-leaved forests where characteristics of stand structure, surface roughness, leaf dimension, and aerodynamic and canopy conductance may interact to partially decouple the canopy from the atmosphere. The implications partial decoupling to understanding the environmental control of canopy transpiration and to the model...
