Investigating ecological and economic aspects of rangeland livestock managements for meat or milk production

Mohammad Farzam; Yasamin Fazeli; mohammad Ghorbani

Volume 74, Issue 3 , December 2021, , Pages 625-632


  Rangeland stockholders are traditionally using their rangeland for producing various livestock productions such as milk, wool and meet (Several Products, SP). However in recent years, meat production as the only product (Meat Production, MP) is implemented in some rangelands of Khorasan Razavi. We compared ...  Read More

Effects of the canopy of perennial plants and livestock utilization rates on the density of soil seed bank in an arid steppe rangeland

zahra nikbakht; Mohammad Farzam; Mohammad Khajeh Hosseini; Hamid Ejtehadi

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

Comparing plant functional types in an old-field and a natural rangeland vegetation

Mohammad Jankju; Fariba Noedoost; Fahimeh Rafiei

Volume 68, Issue 4 , January 2016, , Pages 835-851


  This research was conducted to compare plant functional types (PFT) and traits in an old-field (abandoned for 28 years) and a control site, in the Baharkish rangelands, Quchan, Iran. In the both sites, 40 randomized quadrates were established. Floristic list, frequency, canopy cover and 20 vegetative, ...  Read More

Effects of Shrubs on Preserving Understory Plants against the Livestock Grazing

Tahereh Sadeghi Shahrakht; Mohammad Jankju; Mansour Mesdaghi

Volume 67, Issue 1 , May 2014, , Pages 73-82


  Rangeland shrubs may provide mechanical facilitation on their understory plants, by protecting themagainst the livestock grazing. However, such a facilitation effect may vary depending on the rangelandutilization rate. In a field research, mechanical facilitation of rangeland shrubs was compared in ahighly ...  Read More

Autecology of Zygophyllum atriplicoides in the rangelands of Northern Khorasan province

M. Jankju; F. Noedoost

Volume 65, Issue 4 , March 2013, , Pages 483-494


  Ecological studies on range plants enhance our knowledge on the rangeland ecosystems which are useful for their planning and management.  By doing field and laboratory experiments during 2008-2009, ecological conditions were studied in the main habitats of Z. atriplicoides in the rural and winter ...  Read More
