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

An estimation of topsoil organic carbon by combining factor analysis and multiple regression in semi-steppe rangelands of Lazour, Firouzkooh

Rostam Khalifezadeh; Reza Tamartash; Mohammadreza Tatian; Mohammadreza Sarajian Maralan

Volume 25, Issue 3 , November 2018, , Pages 699-712

Abstract
     Organic carbon is one of the most important soil quality indices, affecting almost all physical, chemical and biological properties of the soil. The purpose of this study was to investigate soil spectral and morphometric factors to estimate the organic carbon of topsoil, using factor analysis ...  Read More
