RISTrend Detection of Drought in Aridand Semi-Arid Regions of Iran Basedon Implementation of Reconnaissance Drought Index (RDI) and Application of Non-Parametrical Statistical Method
Drought is known as one of the main natural hazards especially in arid and semiarid
regions where there are considerable issues in regard to water resources management.
Also, climate changes has been introduced as a global concern...
The study of productive and reproductive traits of first lactation in arid and semi-arid climate Holstein dairy cows of Iran
) and calving interval (CI)) of Holstein dairy cows in arid and semi aridclimate of Iran. Data were collected of 4805 and 58781 first lactation Iranian Holstein dairy cows in arid and semi-arid climate, respectively during 1996 to 2009 by the Animal Breeding...
Three new vagrant eriophyoid species (Acari: Trombidiformes: Eriophyoidea) associated to Rosaceae species from South Khorasan province, East Iran
During the field surveys on eriophyoid mites associated with plant species of the Rosaceae family in semi-arid and arid environments in East Iran (Birjand, South Khorasan, Iran 2016-2017), three new vagrant species (Acari: Eriophyoidea) were found...
Increasing aridity reduces soil microbial diversity and abundance in global drylands
Climate change is increasing the degree of aridity in drylands,
which occupy 41% of Earth’s surface and support 38% of its
population. Soil bacteria and fungi are largely responsible for key
ecosystem services, including soil...
Estimating Evaporation from Lakes and Reservoirs under Limited Data Condition in a Semi-Arid Region
applicable under the limited data condition and arid climate.
Therefore, the objective of this research was to determine the most appropriate evaporation
methods over Doosti dam reservoir in Iran. Eighteen existing methods were tested and ranked...
Paleoenvironment of geomorphic surfaces of an alluvial fan in the eastern Isfahan, Iran, in the light of micromorphology and clay mineralogy
indicated that the illuviation process in the calcareous soils of the arid regions of the eastern Isfahan was probably in response to Quaternary moist conditions. There was no significant difference between clay coating properties of the studied relict...
Spatiotemporal reference evapotranspiration changes in humid and semi-arid regions of Iran: past trends and future projections
This study was undertaken to investigate the refer- ence evapotranspiration (ET0) changes in semi-arid and hu- mid regions of Iran during the past (1966–2010) and future (2011–2099). For detecting possible trend in ET0 over 1966– 2010, the Mann...

Chaotic and Nonlinear Behavior of Arid Ecosystems to Outgoing Drivers
be the result of changing conditions, but may as well be caused by perturbations in system state that force it out of its basin of attraction. Semi arid and arid ecosystems are fragile environments and have low resilience range to respond perturbations...
Effects of range condition on the temporal diet selection by goats in steppe rangelands of Iran
One of the key factors in managing a rangeland is to determine the preference values of its major plant species. We investigated grazing behaviour of a native goat (Garizi) in the steppe rangelands of Iran, from May to ...
