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.

Human activity may be supporting growth of harmful algae in lakes

26 de February 2015Anna Ramon Revilla

The organisms commonly known as blue-green algae have proliferated much more rapidly than other algae in lakes across North America and Europe over the past two centuries – and in many cases the rate of increase has sharply accelerated since the mid-20th century, according to an international team of researchers led by scientists at McGill University with CREAF and CSIC researchers.

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

Nightime global warming limites CO2 uptake by boreal flora

5 de September 2013Anna Ramon Revilla

Nightime temperatures on the planet have increased 1.4 times faster than daytime temperatures. This asymmetry alters carbon fluxes and plant growth in the northern hemisphere, according to a study in which the CREAF is participating.

Dr. Pilar Andrés wins a Marie Curie IOF grant to study soil ecology

28 de June 2013Anna Ramon Revilla

The researcher Pilar Andrés will depart for two years to the USA, to Colorado to study the soil ecology of the Great Plains. Specifically, the project that she presented aims to improve the models that explain the decomposition of organic matter in the soil and contribute to the improvement of models of the carbon and nitrogen cycles.
