The Impact of Climate Change on the Appearance of Some Pathogens in Oak Forests (Quercus frainetto Ten.) and the Analysis of Thickness Increase in the ?umadija Region (Central Serbia)

摘要

Climate change is becoming increasingly frequent. This paper presents the relationship between climate change and the appearance of certain pathogens in oak forests in area ?umadija (central Serbia). The aim of the work is based on experimental sample of land, to carry out research in healthy and infected oak forests and to determine the effect of pathogenic fungi: Microsphera alphitoides and Ophiostoma quercus Armillaria mellea , and the impact in growth in oak forests. Research was conducted on three experimental fields . One pathogen was identified in each experimental field. The effect of fungi is followed by a different soil depth, and in the root zone in oak forests. Furthermore, our goal was to reveal the behavior of fungi in old and young oak forests. The tests were done on nutritive substrates and land suspensions. The research yielded satisfactory definite results, that will be the basis for further monitoring and research.
