Why do we want so many different beetles?

16 de April 2018Francisco Lloret

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?

It’s already available CREAF Talk by Scott Ollinger about nitrogen and carbon assimilation in forests

22 de February 2018CREAF

A new video of CREAF Talks conferences is now available. Scott Ollinger, from University of New Hampshire, USA, talks about basic relations among foliar N and CO2 assimilation in forests, relationships between N concentrations and a suite of functionally convergent plant traits that influence canopy reflectance, and implications for broad-scale N mapping and ecosystem—climate interactions.

Tree herders

14 de October 2017Francisco Lloret

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.

Do drought-affected trees die of thirst or hunger?

16 de August 2017Albert Naya i Díaz

A new study has concluded that, universally, trees that have died from drought are unable to transport water to their leaves. The findings also highlight trees that have drained their carbon reserves since they are not able to carry out photosynthesis. The results of the study will permit the creation of more precise models for predicting the effects of climatic changes on vegetation.

A study with the participation of researchers from CREAF and the UAB warns that increasing droughts could affect forests’ species composition and structure, making them more vulnerable.

Using 3D animations to understand plant anatomy

22 de July 2016Verónica Couto Antelo

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 .
