Numerical taxonomy and seed storage protein analysis of Hyoscyamus species of Iran was carried out with the aim to illustrate species inter-relationship and to check the sub-generic taxonomic treatment proposed for the genus. Cluster analysis of morphological and protein data grouped the species in three separate clusters which supports the relationships of H. niger with H. reticulatus and H. k...

Fungi play an essential role in carbon cycle by decomposing the litter and woody fibers. This study aims to establish a model for describing decomposition multiple fungal activities different environment. We Colony Distribution-Decomposition Model simulate interaction between various fungi describe relationship activity decomposition, which is divided into three sub-models: single colony growth...

Background:Yersinia is a genus in the family Enterobacteriaceae that its species includeYersinia enterocolitica, Yersinia intermedia, Yersinia frederiksenii, and Yersinia kristensenii. Among these species, Yersinia enterocolitica is the most important one that causes various diseases such as gastroenteritis, mesenteric lymph...

Objective: Yield components and genetic contribution have the most important in final yield and breeding programs of crop plants. For this purpose, 20 varieties of grapevines with Russia origin were evaluated in Urmia and Takestan research station (under full irrigation and drought stress). Methods: Twenty grapevine genotypes were evaluated in Urmia and Takestan research station (under full irr...

Background & Aim: Drought stress, as a main abiotic stress, has a significant influence on growth and metabolic activities of plant species. In this study, the influence of reduced irrigation on dry herbage, essential oil yield, and chemical components of two thyme species were investigated. Experimental: This study was done in an experimental greenhouse, I.A.U., Shahrekord Branch, Iran at 201...

A dual-frequency approach is proposed to discriminate hemi-boreal forest species using L- and P-band data. First, it shown that L-band less sensitive the structure than P-band. Second, underlying ground topography estimated polarimetric sub-space decomposition at minimize any potential bias. Then, Gaussian backscatter model employed extract vertical The inverted profiles differ significantly ov...

Abstract. Globally, soil temperature to 1 m depth is predicted be up 4 ∘C warmer by the end of this century, with pronounced effects expected in temperate forest regions. Increased temperatures will potentially increase release carbon dioxide (CO2) from soils, resulting important positive feedback on climate change. Dark CO2 fixation microbes can recycle some released CO2, and rates are reporte...
