Effect of altitude gradient on diversity and abundance of wood macrofungi by oak (Quercus castaneifolia C.A.M.) and hornbeam (Carpinus betulus L.) in a Hyrcanian forests of Iran (Case Study: Kheyroud forest)

Fungi are a large group of organisms, which found in different ecological conditions and are as one of the most important component in forest ecosystems. The north forests of Iran often are mountainous and have high habitat diversity, so the study on impact of altitude variation on diversity and abundance of oak and hornbeam wood fungi has need in forest ecosystems. At the first, the desired parcel were selected, and then sampling was sarted in summer and fall seasons from oak and hornbeam stands in harvested parcel, including 110, 207, and 311 from education and research Kheyroud Forest . Full inventori method were conducted 190 wood-decaying fungal samples From macrofungi were collected from oak and hornbeam in three parcels. The result shows wood-dacaying fungi incuding 114 sampels. The collected samples identified bu botany institute, based on microscopic characteristics of fungi. SAS software was used for Duncan test among fungus characteristics (diversity and abundance) and altitude gradient. The result indicated between significant between altitude gradient and abundance of fungi have a significant relationship (p<0.01) . In the altitude from 0 to 400 meter, little wood macrofungi have been identified, and higher than of 800 meters showed maximum of wood macrofungi. Results show it would be related to higher moisture in higher altitudes causes the more abundance of fungus in this range
