For the purpose of marker assisted selection (MAS), six Algerian cultivars and landraces developed locally or introduced from external breeding programs for semi-arid environments were marker characte...
Large grazing herbivores have been reported to determine the structure and function of grassland ecosystems. However, the ecological linkages between structure and functioning components have yet been...
The carbon isotope composition ( d13C) of C3/C4 mixed grassland is reflected in the d13C of diet, hair or faeces of grazers, if 13C discrimination (13 D) between grassland vegetation and these tissues...
The Gonghe Basin is a sandified and desertified region of China, but the distribution of soil organic carbon (SOC) and total nitrogen (TN) along the cultivation chronosequence across this ecologically...
Numerous tanks were constructed and used for irrigation purposes in southern India. With the advent of canal and ground water system of irrigation, they were neglected and found to be in non-usabl...
PAHs concentration in particulate and gas phase was investigated in indoor and outdoor air of urban residential and roadside homes in a semiarid region of India. Samples were collected during winter ...

A typical arid area in China is the province of Xinjiang. The objective of this paper is to present a description of a method based on the energy balance and evaporative fraction, which is obtained by...
The climate of most loess plateau gully area is continental monsoon climate. It is hot , dry, sometimes rain-storm in summer, and cold, windy, occasionally snow in winter. The summer and the winter ar...
Interactions between shallow groundwater and land surface processes play an important role in the ecohydrology of riparian zones. Some recent land surface models (LSMs) incorporate groundwater-land su...
Agriculture in arid and semi-arid lands of Kenya is depends on seasonal characteristics of rainfall. This study seeks to distinguish components of regional climate variability, especially El Niño...
The impacts of clouds and atmospheric aerosols on the terrestrial carbon cycle at semi-arid Loess Plateau in Northwest China are investigated, by using the observation data obtained at the SACOL (Semi...
The impact of dust aerosols on the semi-arid climate of Northwest China is analyzed by comparing aerosol and cloud properties derived over the China semi-arid region (hereafter, CSR) and the United St...
The Tropical Rainfall Measuring Mission (TRMM) carries aboard the Precipitation Radar (TRMMPR) that measures the backscatter (σ°) of the surface. σ° is sensitive to surface soil moisture and vegetatio...
