Subarctic lakes are drying up at a rate not seen in 200 years « New Phoenix

Subarctic lakes are drying up at a rate not seen in 200 years « New Phoenix | Farming, Forests, Water & Fishing (No Petroleum Added) | Scoop.it

The decrease in snowfall observed in recent years in Canada’s subarctic regions has led to worrisome desiccation of the regions’ lakes. This is the conclusion arrived at by researchers from Université Laval, Wilfrid Laurier University, Brock University and the University of Waterloo in a study published this week on the website of the scientific journal Geophysical Research Letters.

The kind of desiccation seen by the researchers is without precedent in 200 years. Isotopic analyses conducted on the remains of phytoplankton accumulated in lakebed sediment show that the lakes have maintained water balance for 200 years. This stability was abruptly disrupted a few years ago.

If the trend of dry summers and less snowy winters continues, as climate models forecast, many of the subarctic’s shallowest lakes could dry out completely. “It’s difficult to predict all the repercussions of this habitat loss,” admits Bouchard, “but it’s certain that the ecological consequences will be significant.”

USINSK, Russia — On the bright-yellow tundra outside this oil town near the Arctic Circle, a pitch-black pool of crude stretches toward the horizon. The source: a decommissioned well whose rusty screws ooze with oil, viscous like jam.

This is the face of Russia's oil country, a sprawling, inhospitable zone that experts say represents the world's worst ecological oil catastrophe.

One Traveling Grizzly Showed Not All Carnivores Who Wander Are Lost. | Farming, Forests, Water & Fishing (No Petroleum Added) | Scoop.it
In 2014, a 20-year-old grizzly bear named Ethyl made an epic 2,800 mile walkabout through Montana and Idaho. U.S. Fish and Wildlife Service biologists knew of her movements because of the GPS collar she wore, which sent weekly data to a satellite. Federal Grizzly Bear Recovery Coordinator Chris Servheen called her traverse into Idaho via the Bob Marshall Wilderness and Mission Mountains, which involved navigating through main streets, landfills, backyards and crossing Interstate 90, "bizarre." While male grizzlies make big movements, females rarely venture far. Yet this was but one of several similar carnivore peregrinations documented in the last fifteen years via GPS-collar technology.

Europe shows that humans and large predators can share the same landscape

Europe shows that humans and large predators can share the same landscape | Farming, Forests, Water & Fishing (No Petroleum Added) | Scoop.it

Photo Credit: Henrik Andrén

"The recovery of large carnivores in Europe is a great success for nature conservation. At one third of mainland Europe, at least one species of large carnivore is present, according to an article in the scientific magazine Science that researchers from 26 countries have contributed to. It is an excellent example that humans and carnivores can share the same landscape, says main author Guillaume Chapron, from the Swedish University of Agricultural Sciences (SLU)

 

By the early 20th century, large carnivores had been exterminated from most of Europe, with just relict populations persisting. Now we have increasing or stable populations of brown bears, wolves, Eurasian lynx and wolverines, and they do not live in a remote wilderness but in a human-dominated landscape.

 

That is a great difference in comparison to the strategies being pursued in other parts of the world where carnivores are mainly protected in large national parks or wilderness areas, separated from people. If Europe had used that model we would hardly have any carnivores at all because there are not enough large areas of wilderness remaining."

Lauren Wood grew up in a family of river guides in the Uinta Basin region of Utah. She navigates tributaries of the Colorado River like her urban counterparts navigate subway systems. She learned to ride a horse, and then drive a car, on the Tavaputs Plateau. And she can name most any gorge or gully in the place she calls home.

But this landscape so familiar to her has transformed over the past decade to one in which drill rigs are more common than cattle herds, and methane emissions have degraded the air quality in this wilderness region to rival that of Los Angeles.

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.

When the ancient oaks disappear they are not immediately replaced by other old oaks. These are few and far between.

Those who own these oaks or know people who do should stand up and protect the oaks when new roads and buildings are under construction, or when pipes and cables are lain underground. 

The number of trees in Norway is actually growing.   There are three times as many new trees in Norway as there in the interwar period.  So there are constantly new spruces and other types of vegetation growing up between the old oaks. They shade the old giants and hasten their deaths.

 

Norwegians can help by clearing vegetation around the trees.

Dead branches and rotten wood are natural features of old oaks and not a sign that they are diseased. Owners can be reminded of this.

Pruning branches on large old oaks is often unnecessary. Professional tree toppers should be summoned if withered branches are in danger of falling on people or the crown needs to be topped to keep a tree from falling.

Old trees in Sweden

Sweden is one of the countries in Europe where quite a few ancient oaks still survive.

This is because the Swedish kings forbid the chopping of valuable trees.

But many were felled when the ban was lifted in the 1800s, partly as acts of protest against the nobility and the Lutheran Church.

This is why many of the survivors in Sweden are found on the former properties of the nobility and church lands.

 

Researcher Nicklas Jansson at Linköping University has been begun a study to see if he can address the loss of these species. He hung up hollow boxes on old oaks and placed old mouldy wood and other materials inside that simulated trunk hollows.

“This was a success. A total of 70 percent of the original life forms in the trunk hollows made footholds in the boxes. The project has now been running for ten years.”

“It would be fascinating to try the same thing here in Norway,” Eik Pilskog says.

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.

Brazil's 'chainsaw queen' appointed new agriculture minister

Brazil's 'chainsaw queen' appointed new agriculture minister | Farming, Forests, Water & Fishing (No Petroleum Added) | Scoop.it
Brazilian president Dilma Rousseff has stirred up the wrath of environmentalists by appointing a controversial advocate of agribusiness and weaker forest conservation as her new agriculture minister.

Kátia Abreu, who has been nicknamed the “chainsaw queen” by her enemies, is included in a new cabinet that rewards political allies who supported Rousseff in her recent narrow re-election victory.

Abreu is a leading figure in the “ruralista” lobby, which prompted the government to weaken Brazil’s forest code. In congressional debates and in her feisty newspaper column, she has called for more roads through the Amazon, congressional control over demarcation of indigenous reserves, more efficient monocultures, and the approval of genetically modified “terminator seeds”.

A team of researchers has identified 125 million hectares (309 million acres) of land suitable for agricultural expansion that won't come at the expense of tropical forests. The study argues that shifting agricultural expansion away from forests to these 'degraded lands' would avoid 13 billion tons of carbon dioxide emissions that would be released were they converted for plantations, pasture, and croplands.

Is there something fishy about the health advice on farmed salmon?

Is there something fishy about the health advice on farmed salmon? | Farming, Forests, Water & Fishing (No Petroleum Added) | Scoop.it
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.”
