What is the future that the Mediterranean forests expect? Climate change is already strongly felt and its impacts reach everywhere. Francisco Lloret tells the current situation and how we will have to prepare ourselves and forests to the coming changes .
CREAF researchers signal climate change and changes in land use as the principal causes. The most impacted are specialized species living in very specific habitats and those producing a number of generations in a single year.
How does water move inside a tree? CREAF researchers are helping to demystify such topics using 3D images wich reconstruct the internal structure of tree branches and trunks, and further, deepening our knowledge on the transport of water and nutrients .
We seek a candidate to apply for a 4 years doctoral fellowship to carry on in the CIBIO (Vila do Conde, Porto) and CREAF (Bellaterra, Barcelona) within the Doctoral Programme in Biodiversity, Genetics and Evolution (BIODIV), funded by the “Fundação para a Ciência e a Tecnologia” (Portugal).
A study by CTFC and CREAF scientists has led to the development of a mathematical model which predicts drought stress in forests. The research shows that forest drought stress depends on climatic conditions as well as vegetation and soil characteristics.
According to a study co-led by CREAF staff published this week in the journal Nature, droughts caused by climate change could result in the death of the tallest tress in tropical forests. For the first time, the scientists have shown that after prolonged water deficit tall trees suffer embolisms in their circulatory systems and die of dehydration.
Researchers from the UAB, CREAF and the National Museum of Natural Sciences (MNCN-CSIC) have analysed how the deterioration of woods caused by droughts associated to global warming are affecting the microbial composition of the soil and modifying carbon cycles.
CREAF participated in a study which proposes that in order to understand the full impact of climate change, it is not enough to study just protected natural areas, which are mature and able to handle change; instead, it is important to focus on the study of those ecosystems which have been altered and are still recovering.
Forests cover one-third of the Earth’s land surface, and they provide many essential ecological, economic and social services. During the last decades, the scientific community has been alarmed by reports of widespread tree and forest mortality worldwide.
A new scientific article published by members of CREAF, the Autonomous University of Barcelona, and the Swedish University of Agricultural Sciences reveals that when a forest is attacked by certain fungi during an episode of drought, tree mortality multiplies. The article explains the two classes of fungi which benefit from situations of drought and how they colonize and end up killing trees through food and water starvation.
The BeWater project launched its first series of meetings on 28 May in La Tordera, Catalonia, Spain. CREAF, the local case study leader, together with consortium partners, met key local stakeholders in order to introduce the project, hear local perspectives on the state of the river basin and discuss potential global change impacts.
