Abstract Late brittle extension is a common feature in orogenic belts, and its role mountain building processes still the subject of debate. Its timing relationship with crustal thickening, topography, basin infill, rock exhumation are key importance determining whether it major factor development or merely causes near-surface secondary effects. We examined this question relation to active arc-...

Root-knot nematodes (RKN) are the most serious plant parasitic nematodes having a broad host range exceeding 2,000 plant species. Quercus brantii Lindl. and Q. infectoria Oliv are the most important woody species of Zagros forests in west of Iran where favors sub-Mediterranean climate. National Botanical Garden of Iran (NBGI) is scheduled to be the basic center for research and education of bot...

Exploitation of the tidal energy resource has been demonstrated to reduce flow speeds and affect the deposition of coarse sediment in the vicinity of Tidal Energy Converter (TEC) arrays, yet the far reaching hydrodynamic and morphological effects have yet to be determined. This impact could be significant in areas where sand banks form regions that exhibit asymmetries in terms of the

Abstract. The Zagros orogenic system resulted due to collision of the Arabian plate with Eurasian plate. region is characterized by ocean–continent subduction and continent–continent collision, convergence velocity shows variations from east west. Therefore, this complex tectonic stress a wide range diffuse or localized deformation between both plates. in situ GPS data are very limited sparsely...

The formation of Pt-Ru nanoclusters (NCs) by sequential deposition of Pt and Ru on a periodically rumpled graphene sheet supported on Ru(0001) is analyzed by atomistic-level modeling and kinetic Monte Carlo simulations. The "coarse-scale" periodic variation of the adsorption energy of metal adatoms across the graphene sheet directs the assembly of NCs to a periodic array of thermodynamically pr...

Karami A, Sefidi K, Feghhi J. 2014. Structure and spatial pattern of land uses patches in the Zagros Mountains region in the west of Iran. Biodiversitas 15: 53-59. Landscape ecology as a new interdisciplinary science, concepts, theories and methods provides for evaluation and management of land. Quantification of landscape patterns has key role in the interpretation and modeling of spatial and ...

A multi-proxy approach was used to examine the geomorphic dynamics and environmental history of an upper deltaic floodplain tract in the Sacramento–San Joaquin Delta, California. Three long cores were collected from the McCormack– Williamson Tract (MWT) and these cores were analyzed for bulk density, loss-on-ignition, fine (clay and silt) content, Al concentration, magnetic susceptibility, poll...

Dead wood biomass can be a substantial fraction of stored carbon in forest ecosystems, and coarse woody debris (CWD) decay rates may be sensitive to climate warming. We used an elevation gradient in Colorado Rocky Mountain subalpine forest to examine climate and species effects on dead wood biomass, and on CWD decay rate. Using a new radiocarbon approach, we determined that the turnover time of...
