HUDECOVÁ, Simona: Changes in oak productivity in Slovakia in the last century (Bachelor Thesis). Technical university in Zvolen. Faculty of Forestry; Department of Planning, Forest resources and Informatics. Supervisor: Ing. Michal Bošeľa, Phd. Zvolen: FF TUZVO, 2020. 43s. The current climate change raises many question about how trees will respond to emerging conditions. Many authors in their research show a long-term increase in tree production, but prolonget drought can have a negative effect on tree growth. A comprehensive analysis of the current situation has not been prepared for the Slovak republic yet. This bachelor thesis deals with the impact of climate change on oak ecosystems, focusing also on the spread of oak in both Slovakia and Europe, discusses about the management in oaks stands and also describes how climate change affects oaks stands either in terms of production or its future distribution. Oak species respond to climate change in two ways. On the one side, some of them react positively, mainly these oaks, which are found in dry habitats, with a lack od minerals and water. For these species, i tis shown that due to the changing climate they reach higher vegetation levels and also they will spread and inhabit. On the other side, there are oaks, such as the predunculate oak (Quercus robur) and the sessile oak (Quercus petraeae) which react on climate change negatively. Although the climate change doesn´t affect these species, it triggers secondary factors (such as various pathogens and tracheomycosis) that will have ideal conditions for reproduction and as climate change is stressful on oaks, they become more vunerable.
