Modelling Above ground net primary production of Sabalan rangelands using vegetation index and non-linear regression
Background and objectives: Alongside with the progresss in satellite sensors, their role on obtaining information and study of the environmental events and phenomena have become increasingly important. One of these precious data which is the basis for many planning and decision making in rangelands, is the above ground net primary production assements. The traditional method of estimating ANPP ...
متن کاملIncreased Precipitation and Nitrogen Alter Shrub Architecture in a Desert Shrubland: Implications for Primary Production
Shrublands are one of the major types of ecosystems in the desert regions of northern China, which is expected to be substantially more sensitive to global environmental changes, such as widespread nitrogen enrichment and precipitation changes, than other ecosystem types. However, the interactive effects of nitrogen and precipitation on them remain poorly understood. We conducted a fully factor...
متن کاملEffect of precipitation variability on net primary production and soil respiration in a Chihuahuan Desert grassland
Precipitation regimes are predicted to become more variable with more extreme rainfall events punctuated by longer intervening dry periods. Water-limited ecosystems are likely to be highly responsive to altered precipitation regimes. The bucket model predicts that increased precipitation variability will reduce soil moisture stress and increase primary productivity and soil respiration in aridl...
متن کاملInvestigation of Vegetation Dynamics and Range Conditions in Central Desert of Iran (Case Study: Haftooman, Khoor and Biabanak)
Abstract. The purpose of this study was to investigate vegetation dynamics and range conditions considering the climatic conditions and soil properties in Haftooman, Khoor and Biabanak deserts, Iran. For this purpose, after determining vegetation types and the associated species, the type of rangeland utilization, grazing season, the livestock type, the other relevant information, vegetation da...
متن کاملThe Vegetation of Flat Top Hill: an Area of Semi-arid Grassland/shrubland in Central Otago, New Zealand
New Zealand Journal of Ecology (1995) 19(2): 175-194 ©New Zealand Ecological Society temperatures among the most extreme recorded in New Zealand (Maunder, 1965). The Central Otago region has a complex history of disturbance. Post-glacial forest may never have extended to the drier basins of Central Otago, and the establishment of grassland, possibly through natural fires, preceded human settlem...
