Climate change-induced decline in winds could delay leaf-fall at high latitudes

13 de April 2021Anna Ramon Revilla

Wind dynamics need to be factored into studies that measure the impact of climate change on the rhythms of nature. A study published in PNAS and co-authored by CREAF-based CSIC researcher Josep Peñuelas concludes that a decline in winds is currently benefiting plant productivity.

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.

The climate is changing faster than animals can adapt

24 de July 2019Anna Ramon Revilla

A study just published in the scientific journal Nature Communications presents worrying results on animals’ adaptation to climate change. It concludes that while species are changing some aspects of their lives in response to global warming, they are not doing so quickly enough and do not always make the right changes.

Plants are exposed to frost more frequently as a result of climate change

14 de February 2018Albert Naya i Díaz

Plants' annual growing season has lengthened, exposing them to frost more often at a time when they are particularly sensitive. That can be detrimental to their activity and lead to substantial crop yield losses.

Climate change is causing plants to flower earlier and changing the rhythm of nature

1 de February 2018Anna Ramon Revilla

CREAF and the companies Altran and Starlab have led the design of RitmeNatura.cat, a citizen observatory that encourages members of the public to ‘adopt’ a plant, record the changes it undergoes and provide data that can be used to study the effects of climate change.

#FenoDato seeks citizens to help monitor how climate change is altering nature’s rhythm

19 de January 2016Anna Ramon Revilla

Climate experts, botanists, geographers and ecologists from CREAF and the Autonomous University of Barcelona (UAB) will train citizens to monitor seasonal changes which can be observed in nature. This way citizens will be able to help the scientists study the effects of climate change on animals and plants. Flower emergence, the dropping of leaves, or the arrival of certain birds will be some of the changes to be studied. Once trained, citizens will be able to contribute to European and Spanish phenology observation networks.

Increased daytime temperatures is causing earlier leaf emergence

29 de April 2015Marina Torres Gibert

A study led by a CREAF-CSIC researcher has outlined a new methodology for describing changes in the life cycle of plants caused by planetary warmingwith higher precision. Daytime, rather than nocturnal temperatures determine phenological changes. The increase in temperatures, leading to an earlier spring, alters the global functioning of ecosystems.
