Trees’ risk of climate change-induced death is reflected in their wood

28 de January 2020Anna Ramon Revilla

According to a study led by the Spanish National Research Council (CSIC), the way trees have responded to drought in the past could be a key indicator of their risk of mortality. The study examined growth rings to compare that response in dead and surviving trees.

Some plants do not reproduce every year because of nutrient scarcity

10 de December 2019Verónica Couto Antelo

A study involving three CREAF researchers has found that plants with low nitrogen and phosphorus concentrations in their leaves do not reproduce every year to enable them to reproduce on a huge scale in years in which conditions are right. Oaks, holm oaks and beeches are examples of trees that behave in such a way.

Local climate causes trees around Europe to leaf at different times

27 de November 2019Anna Ramon Revilla

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.

New forests grow faster but are more sensitive to climate change

9 de October 2019Anna Ramon Revilla

A study led by CREAF has found that new forests growing on abandoned rural land are able to capture more carbon dioxide (CO2) from the atmosphere than long-established forests. This effect could be temporary, however, as the wood of their trees is less dense, making them more vulnerable to extreme climate events.

Increased CO2 only leads to faster growth in plants if they have enough water

30 de August 2019Verónica Couto Antelo

According to a study published recently in the journal PNAS, climate change has caused forests to alter the way they grow, in that they only take advantage of the fertilizing effect of carbon dioxide (CO2) to grow faster if they have plenty of water.

Need for re-evaluation of water, forest and agriculture management strategies in Catalan strategy for climate change adaptation

24 de April 2018Albert Naya i Díaz

The final conclusions of the LIFE MEDACC project, conducted by the Catalan Office for Climate Change (OCCC) of the Ministry of Territory and Sustainability, CREAF, IPE-CSIC and IRTA, draw attention to the need to adapt forest, agriculture and water management strategies to the new arid conditions expected as a result of climate change. Since 1973, the water flow at the headwaters of the Muga and Ter rivers has dropped by almost half, and the volume of the middle and lower sections of the Segre has decreased by as much as 60%.

How the forests of the Iberian Peninsula have changed over 25 years?

18 de December 2017Albert Naya i Díaz

The increase in drought episodes and the lack of water in the soil have favored Mediterranean species. At the same time, conifers are losing ground because they are less adapted to droughts. These trends correspond to the period of 1987 to 2012 and have been confirmed through satellite remote sensing images.

For the time being, forests are helping to slow CO2 accumulation and climate change

4 de December 2017Albert Naya i Díaz

A study led by CREAF shows that decreases in pollutant deposition and the increase in atmospheric CO2 have stimulated photosynthesis and carbon sequestration in forests. Therefore, it is crucial to understand how carbon circulates in the atmosphere, in living organisms, oceans, and soils in order to anticipate the effects of climate change.
