Since 1982, Earth has become greener in an area covering 36 million km2, close to two times the size of the United States. Above all, this seems to be the result of a fertilizing effect of atmospheric carbon dioxide (CO2) on plants. The study was carried out with satellite images which can capture this increase in terrestrial leaf area.
Researchers from ICTJA-CSIC, CREAF and the University of Barcelona have extracted a number of sedimentary samples from lake bottoms on the island. These samples have allowed the reconstruction of environmental changes over the past 3,000 years including history of its climate, ecology and culture. The pollen records that had been relied upon previously for such work were not continuous and their interpretation led to the erroneous idea that deforestation of the island was sudden and caused exclusively by human over-exploitation.
In 1966, the USA’s President is Lyndon Johnson, in the USSR it is Brezhnev, in France de Gaulle, in India Indira Gandhi. There is an increasing US involvement in Vietnam’s war (and an increasing refuse of war inside the US).
When an animal has limited information about its environment, a chaotic movement pattern could be an efficient strategy for finding what it needs. For mollusks, this could result from internal neural processes. Understanding the mechanisms for chaos generation and its connection with search behavior could help apply these types of patterns to research on humans.
On April 25th Bernat Claramunt will attend the event, Mountains for Europe’s Future, in Brussels. The event promotes the inclusion of mountain-related topics in the Horizon 2020 research and innovation program.
ECOPOTENTIAL Project is going Online! ECOPOTENTIAL is a large European-funded H2020 project that focuses its activities on a targeted set of internationally recognised Protected Areas, blending Earth Observations from remote sensing and field measurements, data analysis and modelling of current and future ecosystem conditions and services.
This finding is described in an article including CREAF researchers and coauthors Aitor Ameztegui and Lluís Brotons. The study addresses how the superior limit of forest cover in the Pyrenees has changed over 50 years. According to the study, the tree line has advanced upward an average of 40 meters, one of the main causes of this being decreasing pressures from livestock. Contrary to common thinking to date, climate change may play a much lesser role than previously thought.
Let's come back to 1916. The World War I is raging (Battle of Verdun and the Somme). Germany is in search of its ‘lebensraum’, an empire like that England and France already have. We recall the Great War today with the terrible images of Kubrick’s Paths of Glory, Monicelli’s The Great War, Losey’s King and country, Renoir’s La grande illusion, and many other films.
Scots pine is the tree species with the greatest latitudinal distribution between Siberia and the Iberian Peninsula. The death of these pines due to drought does not affect CO2 emissions from forest soil.
