Variation in nitrogen economy of two Stipa species in the semiarid region of northern China
Habitat preference Mean residence time Nitrogen-use efficiency Nitrogen productivity Plant strategies
2015/2/5
How effectively plants utilize nitrogen (N), the most limiting nutrient in natural ecosystems, will largely determine the success of plants in intra- and inter-specific competition. Theory suggests th...

Hydrologic processes in the semiarid regions of the Southwest United States are considered to be highly susceptible to variations in temperature and precipitation characteristics due to the effects of...
A conceptual dynamic vegetation-soil model for arid and semiarid zones
vegetation-soil model semiarid zones arid
2009/5/6
Plant ecosystems in arid and semiarid climates show high complexity, since they depend on water availability to carry out their vital processes. In these climates, water stress is the main factor cont...
The CO2 exchange of biological soil crusts in a semiarid grass-shrubland at the northern transition zone of the Negev desert,Israel
CO2 exchange biological soil crusts semiarid grass-shrubland transition zone
2010/1/18
Biological soil crusts (BSC) contribute significantly to the soil surface cover in many dryland ecosystems. A mixed type of BSC, which consists of cyanobacteria, mosses and cyanolichens, constitutes m...
Gauging the ungauged basin:a top-down approach in a large semiarid watershed in China
