Soil moisture plays a key role in vegetation restoration and ecosystem stability in arid and semiarid regions. The response of soil moisture to rainfall pulses is an important hydrological process, which is strongly influenced by land use during the implementation of vegetation restoration. In this study, vertical soil moisture variations of woodland (Pinus tabulaeformis), native grassland (Sti...

BACKGROUND The Mongolian steppe is one of the most important grasslands in the world but suffers from aridization and damage from anthropogenic activities. Understanding structure and function of this community is important for the ecological conservation, but has seldom been investigated. METHODOLOGY/PRINCIPAL FINDINGS In this study, a total of 324 quadrats located on the three main types of...

in order to sustainable use of rangelands, it is necessary to recognize water, soil, and vegetation cover and analyze their relationships. physical and chemical properties of soil are effective in distribution of plant species in local area. to determine the effects of some soil properties on species distribution of eurotia ceratoides and stipa barbata in baghedar summer region of bafgh, three ...

Abstract The developed system allows to measure the thermal conductivity of solid materials used as insulators in building bioclimatic houses on high Andean zones. A unidirectional heat flow model through a sample dimensions 4.0 cm x 4.2 1.35 has been considered. K-type thermocouples were temperature’s gradient. obtained values were: 0.97 Wm −1 °C for glass, 0.38 ignimbrite, 0.58 roof brick and...

Native grasses interact spatially with themselves and their environment and can therefore be thought of as a system of dependent random variables. One method of modeling the spatial dependence of a multi-species population is a Gibbsian pairwise potential model. Since natural selection operates at the level of individual plants, the information obtained from such a model should provide a greate...

In the course of field research, analysis previously published works and review materials stored in well-known collection funds Siberia (NS, KRAS, SSHZ), information on distribution rare adventitious native plant species Upper Yenisei basin was clarified. For first time, Arctium lappa, Armoracia sisymbrioides, Bupleurum sibiricum, Calystegia sepium, Lolium perenne, Pastinaca sativa, Polygonum s...

The biogenic volatile organic compounds (VOC) emitted by the vegetation of a terrestrial ecosystem play a key role in both regional air quality and tropospheric chemistry. To describe the general emission properties of VOC of different plant functional groups (PFG) in a typical temperate grassland in Inner Mongolia, China, we randomly selected 175 plant species and measured the quantities of is...
