Recently, my friend Paul Zedler raised a question between insidious and philosophical: our scientific procedure based on searching for processes and establishing causal relationships, has no significance unless it translates into actions. I had no other option than accept the premise, otherwise I would get exposed at the top of the infamous ivory tower.
The human footprint on Earth is undoubted and inevitable to some extent . Science and technology, far from contributing to create more inequalities, must be able to mitigate these impacts, contribute to progress and improve the welfare of all the people in the world.
At the end of the 19th century, the border region between Italy and Slovenia had mountains with no trees. A massive reforestation ordered by the Austro-Hungarian Empire allowed to recover forests and revitalize the region. Now, however, those pines planted a century ago are in danger.
Trees that have grown in highly suitable climatic conditions are less capable of dealing with extreme droughts, according to a study that underlines the importance of taking a forest's history into consideration when deciding how best to conserve and manage it.
Evolution leads to an increasing number of species, and that's why it is so difficult for us to know how many of them inhabit the Earth. Should we spend efforts to conserve all of them or would it be enough with just a few?
Some giant trees, such as cedars and redwoods, are an example of great longevity and their populations depend much more on tendencies than on specific traumatic episodes. Climate change and human pressures can put their survival at risk.
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 .
The use of the term 'resilience' has been extended. But success entails risks. When dealing with complex concepts encapsulated in a word, the risk translates into confusion. It is therefore worth entertaining the passage and meditate for a while.
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).
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.
