Spatial variation of soil chemical properties in relation to the canopy of two cushion plants Astragalus myriacanthus and Acantholimon spinosum in Yazd province

Shadi Hazhir; Reza Erfanzadeh; Mohammad Jafari

Volume 28, Issue 3 , October 2021, , Pages 410-423

Abstract
  Soil and plants in natural ecosystems are always interacting with each other. The different structure and characteristics of plant species in an area in the long term affect environmental variables, especially on the soil. The aim of this study was to investigate the effect of two different plant species, ...  Read More

The effect of canopy cover of three species on soil seed bank characteristics in the arid regions Case Study: rangelands of Chenarnaz village in Khatam county, Yazd province

Mahboubeh Hadinejad; Reza Erfanzadeh; Hasan Qelichnia

Volume 27, Issue 4 , December 2020, , Pages 742-751

Abstract
  The persent study was designed to investigate the effect of canopy cover of three woody species, Amygdalus scoparia, Daphne mezereum, Ebenus stellata on the composition and density of soil seed bank under their canopies. Fifteen individuals were selected from each of the woody species in Chenarnaz rangelands, ...  Read More

The research method is descriptive-analytic and the size of sample was defined 24 rangeland users according to Morgan table. Following a review ...  Read More

Application of additive partitioning to study the effect of aspect and elevation on alpha, beta and gamma diversities of plant species (case study: protected area of Geno, Hormozgan province)

Sajad Amiri; reza erfanzadeh; yahya esmaeil pour; reza omidipour

Volume 23, Issue 3 , January 2017, , Pages 645-660

Abstract
   This research was aimed to study the effects of elevation and aspect on diversity components (alpha, beta and gamma) using additive partitioning in the Geno Mountain. All plant species were listed in nine elevation zones (400-1050 m a.s.l.) in southern and eastern aspects of Geno. The cover percentage ...  Read More

Evaluation of crude protein of dry rangeland species in two phenologocal stages and comparing with critical limit needing for native animal (case study: Kahnuj, Kerman province)

Parya Kamali; Reza Erfanzadeh; Seyed Hamzeh Kahnoooj

Volume 23, Issue 1 , June 2016, , Pages 14-22

Abstract
  Determining the forage quality of plant species is among the factors necessary for proper range management. Therefore, the crude protein of 14 species was measured in two phenological stages in Kahnuj (Kerman province) using Kjeldahl methodology. The crude protein content of the study species was compared ...  Read More
