Abstract
Man transports different organisms from one continent to another continent. In new surroundings these organisms can multiply if the environmental conditions are favourable for their development. They come in contact with other organisms which in their evolution they never have met. Parasites and consumers can find host plants which are related to their original hosts but which don`t have efficient defence mechanisms against them. Such harmful organisms can provoke heavy damages to plants and the consequences can be disastrous for whole ecosystems or for man`s economy. Because of universal globalisation, climatic change, increasing transport of goods among continents and because of rapid spread of dangerous diseases and pests of plants, which we are given evidence in forestry in recent time, it is only the question of time when such a harmful organism will be introduced which will pose a threat to an important tree species of slovene forests. The slovenian forest protection have to build capacity for rapid and efficient discovery and determination of new emerging harmful organisms. We propose a research project which would contribute to readiness of Slovenia for invasion of new harmful organisms with the development of new techniques of their detection and determination. The project will introduce new methods of detection of potential harmful organisms, which will be tested in concrete environmental conditions, which will embrace whole spectrum of professional work, from the mode of inspection, technical problems of sampling, laboratory isolations of fungi, rearing of insects in controlled conditions, determination and its techniques, mainly molecular (DNA) diagnostics. The second activity of proposed project is targeted collection of literature data about harmful organisms for forests, their study and transfer of knowledge to professional forestry research, operational forestry and general public. With the publication of research results in foreign scientific journals and in domestic scientific and professional journals the gained knowledge about invasive harmful organisms to forests, their characteristics, methods of detection and determination will be distributed.
Significance for science
In the frame of the project we have found and determined new harmful organisms for forests in Slovenia, which is a contribution to the knowledge of their spread and its principles. New species for Slovenia are: Chalara fraxinea on ashes, Cinara curvipes on firs, Discula destructiva on dogwoods, Mycosphaerella dearnessii on pines, Erysiphe arcuata on common hornbeam. Besides, we detected but did not publish yet the finding of a rust Melampsoridium hiratsukanum on alders and Fromeela mexicana on Duchesnea indica. Extensive field work was performed in connection with the distribution and species composition of the longhorn genus Monochamus in our coniferous forests and the result was the first insight into species composition of these vectors of pine wilt nematode (Bursaphelenchus xylophilus). With the research with fungi from the genus Phytophthora we established that certain isolates are different by their pathogenicity and that certain host trees have different susceptibility for the disease. The result is important for the understanding of pathological processes in forests and indicates the possibility for selection of more resistant individual trees to the pathogens from the genus Phytophthora. With the research with fungi from the Botryosphaeriaceae family, which are the cause of Ostrya carpinifolia dieback on Kras area we have found out that the most important pathogen is the fungus Botryosphaeria dothidea, but in the processes of Ostrya dieback other fungi are also involved. Among them is a fungus from the genus Dothiorella, which is a new species and will be described as such. With this work we have made contribution to the knowledge of Botryosphaeriaceae taxonomy. The results indicate, that the dieback observed in O. carpinifolia is associated with an autochthonous population of B. dothidea, and not with an invasive and introduced species. We were involved in the most up to date research in European forest pathology through the intensive research on ash dieback in Slovenia.
Significance for the country
With the detection of new harmful organisms for forests in Slovenia (Chalara fraxinea, Cinara curvipes, Discula destructiva, Mycosphaerella dearnessii, Erysiphe arcuata) we enabled the official state bodies and forestry practice to plan the control actions against these organisms or to implement new forest tending practices to prevent the economical losses. Wide scale transfer of knowledge to state employees, into the graduate and postgraduate university study and forestry practice was performed.
