RISWorldwide evidence of a unimodal relationship between productivity and plant species richness
data from coordinated surveys conducted
throughout grasslands worldwide and comprising a wide range of site productivities, we
provide evidence in support of the HBM pattern at both global and regional extents. The...
Alpine soil properties are influenced by Dryas octopetala tannins
A multidisciplinary study was conducted to evaluate the influence of tannins isolated from a dominant and polyphenol rich alpine species (Dryas octopetala) on soil properties and activities. Tannins were isolated from Dryas ...
Acclimation of leaf dark respiration to nocturnal and diurnal warming in a semiarid temperate steppe
Effect of short term versus long term grassland management and seasonal variation in organic and conventional dairy farming on the composition of bulk tank milk
The impact of fencing on the distribution of Przewalski's gazelle
Population dynamics of reintroduced Gunnison's Prairie dogs in the southern portion of their range
Effects of Time and Frequency of Clipping on Production and Regrowth of Agropyron trichophorum -Link- Richt in Emam Gholi Summer Rangelands, Ghochan, Iran
Pubescent wheatgrass -Agropyron trichophorum -Link- Richt.- is growing in semiarid regions of Iran at altitude of 500 to 2000 m. Among different grasses growing in Iran, A. trichophorum is relatively resistant to grazing ...
Effects of spring and summer times prescribed burning on spores and colonization of mycorrhiza and five plant species in a dry grassland
Plant-mycorrhiza symbiosis significantly affects plant community dynamic and composition in dry grasslands. On the other hand, fire is a natural component of many dry grasslands worldwide. Prescribed fire, as a restoration technique, may alter...
Comparing plant functional types in the old-filed and a naturl rangeland vegetation
This research was conducted to compare plant functional types (PFT) and traits in an old-field (abandoned for 28 years) and a control site, in the Baharkish rangelands, Quchan, Iran. In the both sites, 40 randomized quadrates ...
Effects of spring and autumn prescribed fires on plant species diversity and ecological groups in a dry grassland
Wildfire is of the major components of dry grasslands, which may significantly affect their composition and dynamics. However in the recent decades, it is intentionally being used for restoration of grazing lands e.g. for reducing thorny shrubs...
