چکیده
In the year 2000, three hundred and eighty-one animals werw caught in 11 locations in the pedunculate oak forests extending across the wider region of the Sava River valley, an area known as an old natural focus of leptospires. Two hundred and twenty-seven animals were investigated for leptospiral carriership, 381 were tested for the existence of specific antibodies to leptospira. Through cultivation of kidney sections in the Korthof’s nutrient medium, 17 strains of leptospira were isolated from 3 species of myomorphous mammals, of which in the house mouse (Mus musculus) the serovar sejroe in 10 animals (71.4%), in the black-striped field mouse (Apodemus agrarius) the serovar pomona in 4 animals (5.4%) and in the yellownecked field mouse (Apodemus flavicollis) the serovars australis, pomona and one unindentified isolate in 3 animals (4.5%), representing a total of 7.5% of animals. Using the microscopic agglutination test in 47 animals (12.3%), antibodies to leptospira were found for 8 serovars, for the most part the serovar pomona, then (in decreasing order) for the serovars saxkoebing australis, and hardjo. The percentage of serologically positive animals ranged from 34.4% in the house mouse, 13,9% in the black-striped field mouse, 10.8% in the yellow-necked field

Growth dynamics of crown shapes in stands of pedunculate oak and common hornbeam
Background and Purpose: Structure of crowns in forest stands is one of the main factors which determines growth and development of trees. Dynamic change occurs with the age of the stand due to silvicultural interventions or natural disturbances during which trees are removed from the stand. The aim of this article is to analyse the structure of the crown shape of pedunculate oak and common horn...
متن کاملThe Importance of CIR Aerial Imagery in Inventory, Monitoring and Predicting Forest Condition
Background and Purpose: The main goal of this paper was to highlight the importance of colour infrared (CIR) aerial photographs for efficient inventory, monitoring and predicting the health status of forests in changed site conditions. CIR aerial photographs from two aerial surveys conducted in 1989 and 2008 were used to identify and analyze the damage in lowland pedunculated oak (Quercus robur...
متن کاملApplication of visual surveys to estimate acorn production of Brant`s oak (Quercus brantii Lindl.) in northern Zagros Forests of Iran
Acorn production plays a fundamental role in the organization and dynamics of oak forest ecosystems. Regarding acorn importance, visual survey methods have been used to estimate acorn production of oak species throughout the world. In this study, the mast indices of Brant`s oak (Quercus brantii Lindl.) were determined in a section of northern Zagros forests, almost 36 ha area, near Baneh, Kurdi...

Economic Evaluation of Carbon Sequestration in Zagros Oak Forests (Case Study: The Pahnus Forest habitat, Chaharmahal and Bakhtiari Province)
Examining the economic value of carbon sequestration in forests is essential, given the risk of global climate change, which has posed a profound challenge to societies internationally. The present study investigates the amount of carbon sequestration and its economic value in the oak forests (Quercus brantii L.) of Pahnus forest habitat with an area of 990 ha, located in Chaharmahal va Bakhtia...
