Volume 72, Issue 3 , December 2019, , Pages 755-767


  Fires are one of the most important factors affecting natural ecosystems. This study was done in order to investigate the effects of fire on soil chemical properties, soil seed bank and vegetation cover in Yeke Bermagh, Highland ranegelands in the southern part of Golestan National Park. After determination ...  Read More

Volume 70, Issue 1 , June 2017, , Pages 43-55


  In the current study, the variation of soil seed bank density was evaluated in two different fire severities, i.e. low and high. Soil sampling was done in Sharlegh site, Golestan national park. Therefore, 5 soil samples for both grass patches and shrub patches in each burnt and control sites were selected. ...  Read More

Volume 69, Issue 3 , December 2016, , Pages 777-788


  The study of soil seed bank provides useful information on management and restoration of natural ecosystems. In the arid environments, some perennial plants may cause accumulation of seed bank under their canopy, thereby protecting them against the livestock herbivory and the other environmental factors. ...  Read More

Study on the effect of soil chemical characteristics and crown canopy of Ziziphus spina-christi L. on soil seed bank characteristics

Moharram Ashrafzadeh; Reza Erfanzadeh

Volume 66, Issue 4 , March 2014, , Pages 477-491


  This study was carried out to investigate the effect of crown canopy of Ziziphus spina-christi on seed bank characteristics (density and similarity with above ground flora) in two sites with saline-alkaline and alkaline soils. In each soil, forty plots were established, half in and half outside of Z. ...  Read More

The effect of grazing on density, diversity and richness of soil seed bank in mountainous rangelands (case study: Waz watershed, Mazanderan province)

Paria Kamali; Reza Erfanzadeh; Hasan Ghelichnia

Volume 66, Issue 4 , March 2014, , Pages 583-593


  This study aimed to investigate the effect of animal grazing on soil seed bank characteristics in the northern slopes of Alborz. For this purpose, soil seed bank characteristics were compared between grazed and ungrazed areas. Therefore, four transects perpendicular to the sides of exclosure inside and ...  Read More
