Considering the current state of the Zagros forests and the necessity of using information related to quantitative characteristics in the management of these forests, it is essential to prepare more accurate information so that the control of this area can be done more accurately. One of the ways to obtain statistical information is linear sampling (transect.( In this regard, the present study ...

We map the lateral variations of P-wave velocity beneath Zagros collision zone in Iran down to 800 km depth by regional travel time tomography. invert 32,293 relative residuals from five temporary seismic networks across NW and central northern Iran, a large number permanent stations distributed over Iranian Plateau. A salient feature our model is ~225 thick lithosphere Zagros, almost twice as ...

[1] We use the GEOS-Chem chemical transport model to interpret observations of tropospheric ozone from the Tropospheric Emission Spectrometer (TES) satellite instrument in summer 2005. Observations from TES reveal elevated ozone in the middle troposphere (500–400 hPa) across North Africa and the Middle East. Observed ozone abundances in the middle troposphere are at a maximum in summer and a mi...

Hypogastrura persica sp. nov. is described from the Zagros Mountains (Kermanshah Province, Iran). The new species can be distinguished from two nearest congeners, namely H. exigua Gisin, 1958 (Alps) and H. magistri Babenko, 1994 (Siberia), by the body size, the number of sensilla on antennal segment IV, the number of setae on dens and ventral tube as well as chaetotaxy of abdominal terga IV and...

This study quantifies the significance of southerly water vapour fluxes, associated with the Zagros Mountains barrier jet, on precipitation occurring in the Eastern Fertile Crescent region and its change due to global warming. Precipitation events are simulated using a Regional Climate Model (MM5-Noah) driven by boundary conditions from a CCSM global climate model simulation with the SRES A2 em...

.  Introduction Old trees are important and key elements of forest sites and are of great value in terms of forest management, reforestation, silviculture and ecology. Although old trees constitute a small percentage of forest trees, they account for a large share of forest carbon reserve and play a vital role in carbon storage. Understanding the how geographical and site distribution of thes...
