Comparison of non-parametric and parametric species distribution models (SDM) in determining the habitat of dominant rangeland species (Case study: Khetteh Riz Rangelands)

Mansoureh Kargar; Zeynab Jafarian; Reza Tamartash; Seyed Jalil Alavi

Volume 25, Issue 3 , November 2018, , Pages 512-523

Abstract
      Ecologists and environmental managers emphasize the use of predictive models to examine the species distribution patterns. The purpose of the present study was to investigate the efficiency of the generalized linear model (GLM) and generalized additive model (GAM) in determining the ...  Read More

Zeynab Jafarian; Farzad Ahmadi; mansoureh Kargar

Volume 24, Issue 4 , January 2018, , Pages 768-777

Abstract
  This study was carried out in Bolban Abad, Kurdistan province, Iran, in order to investigate the changes in species diversity and functional diversity of vegetation under different grazing intensities. In this study, the data of three sites with different grazing intensity (low, moderate and heavy) were ...  Read More

Variability of Soil Properties Affected by vegetation canopy cover and different grazing intensities

Amirhosein Kavianpour; zeynab Jafarian; Abazar Esmaeli Ouri; Ataollah Kavian

Volume 23, Issue 3 , January 2017, , Pages 593-605

Abstract
  Soil is a suitable bed for plant growth and development of vegetation, so that if it is not conserved, it will result in the nutrient deficiency, soil erosion and degradation of natural resources. In this research, the spatial variability of some chemical and physical properties of soil was investigated ...  Read More

Determination of relationships between dominant plant species with environmental factors and satellite data using logistic regression (case study: Rineh Rangeland, Mazandaran province)

Zeinab Jafarian; Hossein Arzani; Mohammad Jafari; Ghavamedin Zahedi; Hossein Azarnivand

Volume 19, Issue 3 , December 2012, , Pages 371-381

Abstract
  This research was aimed to investigate the relationships between dominant rangeland species and environmental factors in the Rineh rangelands located on the southern slope of Damavand Mountain. Stratified random sampling method was applied and the study area was classified to 37 sample units based upon ...  Read More
