Un paleontólogo de la Universidad de Zaragoza e investigador del Instituto de Investigación en Ciencias Ambientales de Aragón (España), Eustoquio Molina, ha indicado que el mundo vive el sexto gran periodo periodo de extinción debido a que cada hora desaparecen tres especies, con lo cual dejan de existir 72 variedades de animales a diario y alrededor de 30.000 cada año, según un comunicado difundido por la Academia Mexicana de Ciencias y publicado por el portal mexícano Infórmate.

Bird populations across Europe declining rapidly
Bird populations across Europe have experienced sharp declines - a staggering 421 million birds over the past 30 years - with the majority of losses from the most common species, a research shows.
The decline in bird populations can be linked to modern farming methods, deterioration of the quality of the environment and habitat fragmentation, the study noted.
Around 90 percent of these losses were from the 36 most common and widespread species, including house sparrows, skylarks, grey partridges and starlings.

Australia targets wildlife extinction
Australia's Environment Minister Greg Hunt has pledged to end the
extinction of native mammal species by 2020, with a focus on culprits
such as feral cats.
Hunt said Australia had the worst rate of mammal loss in the world and the nation's "greatest failure" in environmental policy was protecting threatened species.
"Our flora and fauna are part of what makes us Australian," he said in a speech late Wednesday.

Guangzhou using invasive species against mosquito-borne fever
Southern Chinese authorities' introduction of an invasive fish species
to combat a surge in dengue fever has sparked fears that the practice
will break the environmental balance.
The water bureau in Guangzhou Municipality, China's third-largest city, has reacted to the mosquito-borne disease by adding mosquitofish to "controllable static waters." While the fish are named for their diet of mosquito larvae, they are also known for harming indigenous species worldwide.

Commission welcomes the Council's adoption of the Invasive Alien Species Regulation
European Commission, Statement, Brussels, 29 September 2014:
Today the EU adopted legislation that will tackle the rapidly growing threat to biodiversity from invasive species. The Regulation is a crucial step towards achieving the EU's 2020 biodiversity targets, while also delivering on a commitment under the Convention on Biological Diversity to establish rules to address the threats posed by these species.
European Environment Commissioner Janez Potočnik said: "This
new Regulation fills a long-recognised gap in EU biodiversity
protection.

BLUEFIN TUNA: THE LONG PATH OF RECOVERY
Bluefin Tuna is an emblematic species, fished and appreciated all across the globe. But when I took office four years ago, the state of the stocks was extremely alarming. We were exporting and eating more bluefin tuna than we were expected to catch!
In 2012 we managed to take action at global level: we implemented, within the International Commission for the Conservation of Atlantic Tunas (ICCAT), a very strict recovery plan based on advice by scientists.

Invasive alien species: "The damage and costs continue to increase"
One of the worst threats to Europe's biodiversity and ecosystems is plant and animals species coming from other countries and continents, which often cause the near extinction of native species. On 16 April MEPs approved new rules to tackle this issue. “Invasive alien species are the second most significant threat to biodiversity after habitat loss and they are also recognised as a major cause of species extinction,” said Pavel Poc, the MEP responsible for steering the proposal through the EP.

Environment: Commission takes Greece to court over failure to protect iconic species
European Commission, Press release, Brussels, 28 March 2014:
The European Commission is taking
Greece to Court for a failure to provide adequate protection for
endangered sea turtles. The case concerns developments in Kyparissia Bay
in the Western Peloponnese, one of the most important nesting beaches
for caretta caretta loggerhead turtles in the
Mediterranean, and an area protected under EU legislation. A high
number of developments and construction activities are being tolerated
and given permits in the area, and the developments are having a
significant negative effect on the endangered turtles. On the
recommendation of Environment Commissioner Janez Potočnik, the
Commission is referring the case to the EU Court of Justice.

Invasive alien species: MEPs reach agreement with the Greek Presidency
Plans to prevent the introduction or halt the spread of
“invasive alien species” of plants, animals or insects that cause
ecological and economic damage were agreed by MEPs and the Greek
Presidency of the Council on Wednesday. The draft legislation, which
would require EU member states to coordinate their efforts, provides for
a ban on species declared to be of “Union concern”.
“Invasive alien species cause damage worth at least €12 billion every year in Europe and many member states already have to spend considerable resources in dealing with them”, said MEP Pavel Poc (S&D, CZ) who is steering the legislation through Parliament.
