Species such as goats, ants, rats, cats or wild blackberry bush, for invasive alien flora and fauna of the Galapagos Islands, threatens the balance of one of the most special places on the planet, where 97 percent of the territory is protected.

The Galapagos National Park (GNP) made a thorough job of eradicating these species were introduced into the archipelago of Ecuador, in their struggle to maintain the unique richness of a fragile ecosystem, which is guarded carefully by the rangers.

The conservation institution maintains an exhaustive control of all organic material entering the archipelago, as well as working hard in combat, non-invasive techniques for the environment against these species.

Why South America meets the widest range of plants and animals on the planet? One study, with participation of the Conejos Superior de Investigations Scientifics (CSIC), proposes an explanation beyond ecological factors: the authors reveal the key role played by the birth of the Andes in the emergence and spread of tropical biodiversity a finding that challenges the traditional view that considered the Amazon River drives the expansion of the biodiversity of the region.

Hundreds of millions of people will be affected by melting glaciers and reduced snow-covered as a result of climate change, the Programmed has warned the UN Environment Programmed (UNEP) in a new report.

“Only the loss of snow and glaciers in the mountains of Asia would affect approximately 40% of world population,” says the report “Global Outlook for Snow and Ice ‘, presented at Nairobi, UNEP headquarters.

But other areas like the Pyrenees, the Alps or the Andes, will also be severely damaged by the impact, it added, which analyzes current trends and possible future development of ecosystems of ice and snow as glaciers, rivers and lakes ice cream.

According to a team of U.S. researchers, the icebergs around Antarctica, far from being sterile ice cubes, are full of activity that may have an important role in combating climate change.

Small marine ecosystems that form around the ice blocks with melted water mixed with sea water, can serve to absorb carbon dioxide from the atmosphere and plunging into the ocean, since the algae absorb carbon -releasing oxygen through photosynthesis and then pass the food chain. They become a focal point for small fish, algae and even birds.

One of the main consequences of climate change has been the increase in temperature, which has led to multiply the appearance of icebergs in the southern waters, chunks of ice ranging from a few inches square that protrude from the surface to others as large as European countries.

Spain lead for the first time a research project of the European Space Agency, developed by the CSIC and the Polytechnic University of Catalonia, from space to measure the salinity of sea and soil moisture, and improving knowledge on climate change .

The announcement of this project, called SMOS, has coincided with the launch of SMOS Barcelona Expert Centre, who will be dealing with process data from the mission and coordinate the scientific activity of the fifty participating Spanish.
