Tropical forests are the terrestrial plant ecosystems to which climate change poses the greatest risk

20 de March 2019CREAF

A study involving CREAF's Josep Peñuelas has identified the optimal temperatures of terrestrial plant ecosystems throughout the world and indicates the size of their margin for adaptation to warming. Outside that margin, ecosystem growth slows sharply.

The greening of the earth is reaching its limit

19 de September 2017Albert Naya i Díaz

A new study led by Josep Peñuelas and published in Nature Ecology and Evolution reveals that CO2 abundance in the atmosphere no longer has a powerful fertilizing effect on vegetation. The greening that has been observed in recent years is slowing and this will cause CO2 levels in the atmosphere to rise, thus increasing temperatures and leading to increasingly severe changes in climate.

When the spring is warm and dry, seed production is increased in forests across Western Europe

31 de August 2016Albert Naya i Díaz

The North Atlantic Oscillation (NAO), an important atmospheric phenomenon affecting the meteorology of the whole of Europe, impacts the quantity and timing of seed production in the continent's forests. When the NAO favors a dry and warm spring, most of the studied forests produced more seeds and this is also done in a more synchronized manner.

Close to 50% of phosphorus emitted to the atmosphere is a result of human activities

15 de December 2014Anna Ramon Revilla

According to the study in which CREAF participated, China contributes 43% of this amount. For decades it had been thought that human activities were responsible for only around 5% of atmospherically-circulating phosphorus. More phosphorus in the air means more phosphors deposited on the ground. This can boost plant growth and the capacity to sequester atmospheric CO2; for that reason human activities may be altering the phosphorus and carbon cycles to a degree which was previously unknown
