Population structure and natural regeneration of Allanblackia floribunda oliv. (Clusiaceae) in a forest concession of East Cameroon
Allanblackia floribunda Oliv. a plant known for its nutritional, economic, industrial and therapeutic qualities is less studied in research centres. Apart from primary studies already carried out, the population structure and natural regeneration arouse much questioning. The follow up of species into FMU 10 044 and on the farmland was realized with the aim of […]
Tolerence of Festuca ovina to different severities of simulated grazing effects in semi-arid Rangelands, Kurdistan, Iran
For assessing simulated grazing effects on Festuca ovina as an important species, two exclosure field established before 2007 growing season in Majidabad rangelands as representative for semi-arid rangelands in major parts of west of Iran.
