“…Extreme weather phenomena are becoming more and more frequent all over the world (WMO, 2011;Rahmstorf and Coumou, 2011;Coumou and Rahmstorf, 2012), which suggests that climate change is not just a future threat but is also an accelerating process in the present. The impacts of climate change can be detectable at different levels (e.g., community (Woodward et al, 1998) in species (Johnston and Schmitz, 1997), in population (Cochrane et al, 2014)) and they have already been examined on various aspects (mainly distribution (Parmesan and Yohe, 2003;Thuiller et al, 2005;Molnár V. et al, 2011) but also in survival, phenology (Fitter and Fitter, 2002;Morellato et al, 2016) or reproductive success (Ackermann, 1989 of many different species or communities (Parmesan and Handley, 2015;Molnár, 2015). Understanding the species' answer to this changing environment is extremely important in the case of plants, as their primary productive role is one of the essential components of almost all ecosystems on the Earth.…”
