Significance for science
Changes of temperature in forest ecosystems can beo f a global nature, as proposed in different climate change scenarios, or of a local anthropogenic nature, including land use changes, soil exposure and consequently higher temperature absorption. The main factor in netto primary productivity in forest soils are soil organisms in mycorrhizosphere, particularly fine roots and mycorrhiza as the key components in the soil parts of forest ecosystems.Our results have shown that already small differences in temperature influence on fine root and fungal mycelium growth and development, and thus on carbon dynamics in forest trees and forest ecosystems. Our studies have contributed to the understanding of the impacts of heavy forest machinery on forest soils and influences of changed temperature regimes on net primary production (NPP) in forest soils. The exposure of bare soils due to heavy forest machinery influences tree roots which are exposed to elevated temperatures. Forest soils become compressed, reducing water, nutrients and aeration availability to roots. All these changes are a stress for the plants, reducing the NPP. Our results at Osankarica (Pohorje) confirmed the hypothesis that forest trees reduce their rooting density at the cart tracks and replace them with an accelerated growth at the border of these tracks, when compared to the control growth of fine roots as observed in minirhizotrons in the field. Direct impacts of different temperature regimes on fine root growth and mycorrhizal functioning in experimental conditions were applied also in development of a mechanicistical model of carbon dynamics. With analyses of mycorrhiza on beech seedlings at the time of planting we have established the basis for comparison with mycorrhizal community and root growth after a certain period in different temperature regimes, as well as to understanding physiology of these ectomycorrhizal fungi and fine roots of beech seedlings in future changing environmental conditions.
Significance for the country
Heavy forest machinery does not only disrupt the local tree root systems but also influences the development of mycorrhizal fungi. Mycorrhizal mycelium together with roots of plants form a network encompassing a broader area around the direct site of the work in the forest. These results were presented publicly in journals and workshops for forest practice and for end-users, in order to help different users, forest management planners and forestry companies for exploitation of wood and other forest functions. Studies at the direct site of forest machinery application was also used in preparation of background materials for standards and norms for planning of works in forests. Within this project we have developed experimental infrastructure and knowledge, some systems were proposed as patent applications, with the project we have contributed to scientific development of PhD students as well as undergraduate students of forestry and microbiology. Several methods were first described and published within this project, and so were the Standard operation protocols for laboratory practices. The studies of influences of temperature regimes on fine root growth and mycorrhiza, and therefore also NPP, were applied in experimental models of the impacts of predicted climate change scenarios on calculations of carbon dynamics in forest ecosystems. Additional methods were proposed to be included in monitorings of forest ecosystems, namely molecular identification of soil organisms and analysis of C dynamics in fine roots of forest trees.
