Earthworms invade New England

Earthworms invade New England

Beavers reshape landscapes with their dams. Wolves control elk populations. Sea otters protect kelp forests by eating sea urchins. These are what ecologists call «keystone» species: critters that control an ecosystem and have a disproportionate impact on other species. And in the forests of New England, what are the keystone species? Put earthworms on the […]

Toxic ocean conditions during major extinction 93.9 million years ago quantified: Doesn’t take much sulfide to impact ocean life

Toxic ocean conditions during major extinction 93.9 million years ago quantified: Doesn’t take much sulfide to impact ocean life

Oxygen in the atmosphere and ocean rose dramatically about 600 million years ago, coinciding with the first proliferation of animal life. Since then, numerous short lived biotic events — typically marked by significant climatic perturbations — took place when oxygen concentrations in the ocean dipped episodically. The most studied and extensive of these events occurred […]

Coral reefs may be able to adapt to moderate climate change

Coral reefs may be able to adapt to moderate climate change

Coral reefs may be able to adapt to moderate climate warming, improving their chance of surviving through the end of this century, if there are large reductions in carbon dioxide emissions, according to a study funded by NOAA and conducted by the agency’s scientists and its academic partners. Results further suggest corals have already adapted […]

Study of Brazilian Amazon shows 50,000 km of road was built in just three years

Study of Brazilian Amazon shows 50,000 km of road was built in just three years

Nearly 17,000 kilometres of road were built in the Brazilian Amazon rainforest every year between 2004 and 2007. Although road-building is a major contributor to deforestation and habitat loss, the way in which road networks develop is still poorly understood. A new study is among the first to measure the number of roads built in […]

Fracturarea hidraulica ar putea fi cauza unei serii de mici cutremure din SUA – studiu

Fracturarea hidraulica ar putea fi cauza unei serii de mici cutremure din SUA – studiu

  Serviciul de prospectare geologica al Statelor Unite (USGS) a studiat seria de mici cutremure care lovesc in mod repetat Oklahoma si a ajuns la concluzia ca acestea ar putea fi cauzate de eliminarea apelor uzate, de la extractia de petrol si gaze, fenomen cunoscut sub numele de fracturare hidraulica sau fracking. Mai mult de […]

Fish population recovery in marine reserve

Fish population recovery in marine reserve

Protection in the Medes Islands marine reserve started more than 25 years ago. Dusky grouper, zebra seabream and European seabass have practically reached their carrying capacity, whereas brown meagre is still approaching population stabilization and common dentex is still increasing. One exception to these trends is gilthead seabream, which decreased probably due to fishing just […]

Monkey that purrs like a cat is among new species discovered in Amazon rainforest

At least 441 new species of animals and plants have been discovered over a four year period in the vast, underexplored rainforest of the Amazon, including a monkey that purrs like a cat. Found between 2010 and 2013, the species include a flame-patterned lizard, a thumbnail-sized frog, a vegetarian piranha, a brightly coloured snake, and […]

Exploatarile miniere din Maramures au lasat in urma 17 iazuri de decantare si peste o suta de halde de steril

Exploatarile miniere din Maramures au lasat in urma 17 iazuri de decantare si peste o suta de halde de steril

Exploatarile miniere din Maramures au lasat in urma probleme ecologice deosebite care pot genera oricand in accidente ecologice. Potrivit unor estimari mai vechi, pentru ecologizarea iazurilor de decantare din Maramures e nevoie de peste 91 de milioane de euro. Anul acesta s-a alocat numai 15% din fondurile solicitate si fundamentate. Dupa aderarea Romaniei la UE, […]
