Estimating the potential of seed production and dispersal in mountain grassland of central Alborz (Case study: rangelands of Sorkh-Abad Savadkooh, Mazandaran province)

jasem yousefi; jamshid ghorbani; maryam shokri; seyed hasan zali

Volume 22, Issue 4 , March 2015, , Pages 757-767

Abstract
  Seed production and dispersal are important topics in grassland management as they influence the vegetation structure and dynamics. To understand and better interpretation of changes in vegetation, it needs to identify the species composition in other sources such as the soil seed bank and seed rain. ...  Read More

Changes in diversity, richness and functional groups of vegetation under different grazing intensities (Case Study: Mahoor, Mamasani Rangelands, Fars province)

Parvez Gholami; Jamshid Ghorbani; Maryam Shokri

Volume 18, Issue 4 , September 2012, , Pages 662-675

Abstract
  Overgrazing can alter rangeland vegetation in different ways. In this study, we used diversity, species richness and plant functional groups as the alternative to assess the vegetation response to different grazing intensities. This was done under three grazing intensities (long-term exclosure as reference ...  Read More

Effect of rangeland rehabilitation and restoration on composition and diversity of species seeds in the soil

Golnaz Rokhfirooz; Jamshid Qorbani; Maryam Shokri; Zianab Jafarian

Volume 18, Issue 2 , September 2011, , Pages 322-335

Abstract
  Evaluation of changes in rangeland ecosystem after rehabilitation and restoration projects is important to determine the positive or negative effects of these projects. Parts of species composition in rangelands are in the soil seed bank as living seeds which are a potential for regeneration. Management ...  Read More

Assessment of species richness in Salok National Park, (North Khorasan)

Ali Taya; Hamid reza Naseri; Jamshid Ghorbani; Maryam Shokri

Volume 16, Issue 4 , January 2010, , Pages 456-467

Abstract
  Species richness and biological diversity have been declined throughout the world as a result of human activities. Protected areas are an attempt to conserve the remaining species. Measuring species richness is important for understanding resource condition but heterogeneity in plant distribution make ...  Read More

Vegetation cover change during 25 years, Case of Lar Dam Basin

Seyed Alireza Mousavi; Mahdi farahpour; Maryam Shokri; Karim Solaimani; Mahmood Godarzi

Volume 13, Issue 3 , February 2006, , Pages 186-200

Abstract
  Landsat 7 ETM+ satellite data of 2002 versus vegetation cover map of 1976 were used to: 1- assess the capability of satellite data to prepare vegetation cover classes map and 2- study the vegetation changes trend in an area of about 26858.6 ha in Lar Dam Basin. Field Sample spots were defined after accomplishing ...  Read More
