At this time of year, deciduous trees across Europe are losing the last of their leaves. When will they come into leaf again? A study just published in Nature Communications has shown that while year-to-year leafing date variations can be explained by heat accumulation, local climate is a key factor in geographical variations.
Cities across Europe and China are preparing to green themselves. The Sino-European project Clearing House was officially launched and will be expanding the knowledge of trees and forests in urban areas.
Enrique Doblas is part of a European interest group on climate change adaptation in the forestry sector. CREAF’s knowledge and innovations will be taken into account when planning solutions to fight climate change.
The European project MENFRI was coordinated by CREAF and came to an end in 2016. Its novel approach, centering on cooperation and knowledge transfer, has opened the door to new opportunities, The NODE being one of them.
A study with the participation of Constantí Stefanescu, researcher at CREAF and the Granollers Natural Science Museum, has revealed that the migratory painted lady butterfly makes a trip which is even more difficult than previously thought. While it was already known that the butterfly travels from Europe to Morocco, chemical analyses have shown that it can even go as far as the Sahel, in the process crossing the enormous Sahara Desert.
The response of leaf unfolding phenology to climate warming has significantly reduced in Central Europe23 de September 2015CREAF
Leaf unfolding occurred on average about 4 days earlier every one degree increase in spring temperature between 1980 and 1994, whereas this value dropped to -2.3 days C-1 between 1999 and 2013, a decrease of over 40%. According to this study recently published in the jorunal Nature with the participaction of Josep Peñuelas, researcher from CSIC at CREAF, warmer winters and photoperiod are forcing plants to control their phenology calendars.
