land-use change has strong effects on ecosystem properties, especially on soil carbon storage and it increased global atmospheric co2. degradation and loss of area and quality of hyrcanian forests are the biggest problems in these forests. one of the most important solutions to taking care of these problems is increasing plantations in these areas. therefore, investigation of the effects of dif...

        In this study we evaluate the effects of different types on soil Physical and chemical Properties and plant species biodiversity in the hyrcanian forests of Iran. For this porpuse 33 sample plots were established in 5 vegetation types consist of pure beech (Fagus orientalis), Ash plantation (fraxinus excelsior), spruce plantation (Picea abies), mixed forest and degraded forest. In each ...

The glycoprotein known as glomalin-related soil protein (GRSP) is abundantly produced on the hyphae and spores of arbuscular mycorrhizal fungi (AMF) in soil and roots. Few studies have focused on its amount, composition and associations with soil properties and possible land-use influences, although the data hints at soil rehabilitation. By choosing a primary forest soil as a non-degraded refer...
