ife inside old oaks plays out at a snail’s pace. But these tree dwellers now risk paying the ultimate price as a result of the extensive cutting of trees in 16th and 17th centuries.
Hanne Eik Pilskog, a PhD candidate at the Norwegian University of Life Sciences in Ås, has spent two years investigating the hollow cavities of old oak trees in the Agder Counties and around the town of Larvik.
She is concerned about the phenomenon that biologists call the extinction debt – the future extinction of a species due to events in the past.
The elephant population in Laos is dwindling at an alarming rate. With more animals dying off than being born, the pachyderms face a real crisis. Their numbers as well their habitat need monitoring and preservation.
WASHINGTON -- Most coastal regions of the United States will see 30 or more days of flooding by 2050 thanks to sea level rise, according to new research the National Oceanic and Atmospheric Administration released Thursday.
NOAA's researchers looked at the anticipated frequency of what the National Weather Service considers nuisance flooding, which are floods that are 1 to 2 feet over the regular local high tide and are enough to cause problems but not pose active threats to human life. Some areas of the U.S. are already seeing increased flooding, the researchers said, and it's only going to get worse.
"Existing computer models may be severely underestimating the risk to Greenland's ice sheet — which would add 20 feet to sea levels if it all melted — from warming temperatures, according to two studies released Monday.
Satellite data were instrumental for both studies — one which concludes that Greenland is likely to see many more lakes that speed up melt, and the other which better tracks large glaciers all around Earth's largest island."
As well as being masters of water engineering, the Romans also engaged in a long distance trade in water across the Mediterranean - embodied in grain, oil, wine, cloth, metals and other goods. They also discovered the food-water-energy nexus - and not in a good way. We need to heed the warnings from Roman history.
Warming of the Pacific Ocean off Washington state could destabilize methane deposits on the seafloor and trigger a release of the greenhouse gas to the atmosphere, according to a new study published in Geophysical Research Letters.
In the worst-case scenario, if oceans warm by up to 2.4 degrees Celsius by 2100, the volume of methane release every year by 2100 would quadruple the amount by the Deepwater Horizon oil spill, the study estimates.
We preserve our cultural identity and we take care of the environment to ensure that future generations can peacefully and safely coexist with nature in the same way. But oil exploitation would inevitably mean an end to our life and culture as we kno...
SMOKED salmon is the easy part of Christmas. Throw it on brown bread, with lemon and black pepper, and the innocents will think it’s posh and that you’ve spent a lot.
But you can get 100g of Everyday Value smoked salmon in Tesco — “responsibly sourced from the waters around Scotland, Norway or Ireland” — for €3.59.
But, today, as many of us prepare for the big Christmas supermarket shop, the Friends of the Irish Environment have ramped up their boycott of farmed salmon, strengthened by the news that the international Slow Food Movement — which counts among its supporters Bridgestone’s Sally McKenna and that icon of Irish sustainable food, Darina Allen — has condemned intensive open-pen fish farms.
“Open-net pen aquaculture is not a solution to the problem of overfishing,” says Slow Food.
“It damages natural ecosystems on a local and a global level, including wild stocks, habitats and water quality.”
A group of giant agri players, including Coca-Cola, Proctor & Gamble and Unilever, has set out plans that will inform its drive towards more sustainable agriculture in the US in the coming years.
The 66 grower organisations, agribusinesses, food, beverage and retail firms that make up the Field to Market: The Alliance for Sustainable Agriculture have committed to achieve a series of goals designed to find sustainable practices for corn, soybean, wheat, cotton, rice, potatoes and other crops. Th
What happens to degraded pastureland once the cows are kicked out? After years of letting the area rest, does it eventually become what it once was? Not likely. When disruptions such as invasive species and human interference are introduced to an area, ecological succession doesn’t occur the way it should naturally.
If you've ever wondered why the ancient structures of Rome have endured for millennia, when our own modern concrete is susceptible to cracks and crumbles, well, now you have your answer. Researchers recreated the Roman recipe and discovered that the formation of a certain kind of crystal in the concrete is the reason for the durability.
At 63, most parents are probably going to a few graduations, playing with their grandkids or just relaxing after seeing their children to adulthood. Wisdom isn't most people. In fact, she's an albatross. And at 63, the world’s oldest known, banded, wild bird just laid her newest egg.
Britain’s fishermen will be allowed to increase their catch of cod and other key fish species next year after late-night wrangling between EU ministers in Brussels resulted in a new set of fishing quotas that flout scientific advice.
The quota for cod catches for 2015 will increase by 5% on last year, though scientific advice suggested that it should be cut by 20%.
Letendre, the president of the Carmel River Watershed Conservancy, was not so interested in the forested slopes of the Santa Lucia Mountains as he was the tableau of human engineering that stretched out before him.
Close to 6,000 hectares of community forests were recently recognized by the Kratie Forestry Administration in northeast Cambodia, extending conservation management to natural habitats along the Mekong River in one of Asia’s last intact lowland ecosystems. The agreements designating the two community forests, one in O’Krieng village and the other in O’Kok village, were signed in December 2013, with approximately 200 stakeholders attending the signing ceremony.
A stark depiction of the threat hanging over the world’s mammals, reptiles, amphibians and other life forms has been published by the prestigious scientific journal, Nature. A special analysis carried out by the journal indicates that a staggering 41% of all amphibians on the planet now face extinction while 26% of mammal species and 13% of birds are similarly threatened.
Many species are already critically endangered and close to extinction, including the Sumatran elephant, Amur leopard and mountain gorilla. But also in danger of vanishing from the wild, it now appears, are animals that are currently rated as merely being endangered: bonobos, bluefin tuna and loggerhead turtles, for example.
In each case, the finger of blame points directly at human activities. The continuing spread of agriculture is destroying millions of hectares of wild habitats every year, leaving animals without homes, while the introduction of invasive species, often helped by humans, is also devastating native populations. At the same time, pollution and overfishing are destroying marine ecosystems.
