CREAF researchers challenge the notion that nitrification occurs only in soil

5 de February 2019CREAF

Human-induced increase in nitrogen deposition profoundly alters nitrogen (N) cycling globally. Yet, the ultimate fate of nitrogen deposition on forest ecosystems isn’t fully understood. Rossella Guerrieri, a Marie Skłodowska-Curie fellow in CREAF sheds light on the overlooked leaf microbial transformations of nitrogen deposition and its contribution to N cycling.

Nitrogen available to plants in decline

13 de December 2018Anna Ramon Revilla

According to an article published in Nature Ecology & Evolution, the authors of which include CREAF postdoctoral researchers Sara Marañón and Rossella Guerrieri (Marie Sklodowska Curie grant holders), the concentration of nitrogen in plant leaves has been in general decline throughout the world for the last 40 years.

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.

Men from wealthy countries are getting taller because their diet is rich in nitrogen and phosphorus

18 de December 2017Anna Ramon Revilla

Mean male height in countries with a high level of GDP is 23 cm greater than in countries with a low level, a difference that has risen by 1.5 cm over the last 30 years. Thanks to a more varied diet rich in animal products, the annual nitrogen and phosphorus intake of people in wealthy countries is practically twice that of those in poor countries.

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.

“We invest much more time writing scientific publications than making science accessible”

Rossella Guerrieri has a PhD in Forestry and Environmental Sciences and has been a post-doc at CREAF since 2016. Her projects are related to the natural cycles of forests and she is a strong advocate of the social impacts of science.

Phosphorus, once only a nutrient, has become a contaminant on a global scale

17 de March 2017Albert Naya i Díaz

Freshwater ecosystems near densely populated areas have levels of phosphorus which are very high and out of balance with nitrogen levels. This has resulted in altered ecosystem functioning, lower water quality, and has made water conservation more difficult.
