Abstract
Forest ecosystems are more and more frequently constrained and stressed by drought, often accelerated by high temperatures, which affects ecosystem water and carbon fluxes, decreases productivity and increases susceptibility to pests and diseases. Tree mortality is a key driver of forest dynamics and its occurrence is projected to increase. Despite recent advances in our understanding of the physiological mechanisms leading to death, we still lack robust indicators of mortality risk that could be applied at the individual tree scale. However, even several factors affect mortality, plant hydraulic traits occupy a central role in determining survival during drought and the effects of drought on carbon dynamics. It is essential to improve the accuracy with which we can predict the response of trees to drought in order to understand the resilience of forests under future climate regimes. With this research we want: (1) To find long-term climatic and soil determinants of tree mortality in sub-mediterranean area using a regional ecological (drought intensity) gradient. (2) To determine simultaneously the tree functioning and tree-anatomical structures affected during extreme-drought induced tree death process, in order to construct the overall sequence of tree processes and their interrelations leading to tree death. (3) To estimate the ecosystem effects of drought-related tree mortality as synthesis of knowledge on how the changing climate will impact on the mortality of tree species in investigated ecosystem and at regional level. To assess the sequence of physiological processes involved in tree mortality, their interrelations and future ecosystem consequences of this phenomenon, the work will be performed at two spatial scales on sub-mediterranean forests or woodlands frequently affected by drought: (1) regional and (2) tree-level. Research on the regional level will take place on the wider sub-mediterranean area, which extends across NW Croatia, SW Slovenia and NE Italy. Tree-level research will be confined to a narrower area of Podgorski kras in SW Slovenia where we already performed several studies investigating ecosystem and tree functioning on drought-prone karst environment. To realize the proposed work, the project will be organized into working packages which will cover all planned activities. The proposed research subject is interdisciplinary. The project will therefore be carried out by researchers from two research institutions: Slovenian Forestry Institute (SFI) and University of Ljubljana, Biotechnical Faculty.
