in order to investigate variations in plant diversity in dr. dorostkar's forest reservoir, located in gisoum talesh, 44 sampling plots were applied by the randomized-systematic method. the diameter of all tree species (dbh?5 cm) was measured in 400 m2 (20×20 m) square sampling plots. in addition, the number of individuals of shrubs and saplings (dbh?5 cm) were enumerated in circular 100 m2...

background: regarding to the significant of the possibility of the malaria epidemic and nuisance of mosquitoes dur­ing the active season, the fauna and some ecological activities of mosquitoes in related to tree holes were investi­gated from april to december 2009 in neka county of mazandaran province, northern iran. methods: larval collection was carried out from natural, artificial breeding p...

Capacity of garden productions in Iran is such that is accounted as a country that produces thirteen garden products in the world but despite excellent condition in Iran for producing garden products, natural disasters damage production of fruits in the country therefore farmers incur a loss. Pistachio tree has been in danger of destruction and dryness. Thus, in order to reduce loss incurred on...

The present study was focused to examine the combined effects of climate and ultraviolet-B radiation on conifer tree-ring density. Statistical methods were employed to extract tree responses in annual ring density and to identify functional relationship in trees when the level of ultraviolet-B radiation changes regardless of climate variations. In this study, the consideration was given to the ...

For maintaining of Zagros forests role in wild life, water and soil conservation, the suitable solutions and methods for assessing the existing conditions and planning for management of this forests should be given. To detection of suitable sampling method to study tree Diameter at Breath Height in the northern Zagros forest, Blake forest, in Baneeh region, Kurdistan province, and west of Iran ...

It is well-known that, given inorder traversal along with one of the preorder or postorder traversals of a binary tree, the tree can be determined uniquely. Several algorithms have been proposed to reconstruct a binary tree from its inorder and preorder traversals. There is one study to reconstruct a binary tree from its inorder and postorder traversals, and this algorithm takes running time of...
