The ecological relationship between trees is important in the sustainable management of forests. Studying this relationship in spatial ecology, different indices are applied that are based on distance to nearest neighbor. The aim of this research was introduction of important indices based on nearest neighbor analysis and their application in the investigation of ecological relationship between...
In the framework of collection and identification of fungi of Zagros mountains (W and SW Iran), specimens of agaric fungi with subterraneandevelopment were collected from oak forests in Chaharmahal-va-Bakhtiari province. Native people of Dopolan and Rahimabad used hypogeous fruit-bodies of fungus as edible fungi. Excavation was done and fungal samples were found at 15–30 cm soil depth, near Oak...
