Researchers Explain Arctic Lake Disappearance
Posted by Nature World News: None Given on August 1st, 2013
Nature World News: The Arctic lake has disappeared, leaving behind ice and clouds in the region. The pool of water drained through cracks in the underlying ice July, 29. Researchers at UW Applied Physics Laboratory said that ice melts at the Arctic every summer. "Every summer when the sun melts the surface the water has to go someplace, so it accumulates in these ponds. This doesn't look particularly extreme," said Jamie Morison, a polar scientist at the UW Applied Physics Laboratory and principal investigator since...
Farm Chemicals Accumulating in Wild Frogs in California
Posted by Nature World News: None Given on July 26th, 2013
Nature World News: Commonly used chemicals in farms of California's Central Valley have accumulated in and affected a native frog species since many decades, researchers said.
Researchers found that pesticides are affecting the Pacific chorus frog Pseudacris Regilla- a species of frog that can be found in the Sierra Nevada mountain range. Chemicals, such as pesticides and insecticides, can disrupt the frogs' immune system, making it vulnerable to various diseases.
"Our results show that current-use pesticides,...

Posted by Nature World News: None Given on July 24th, 2013
Nature World News: The stable ice on Antarctic- the coastal permafrost- is melting faster than expected, a new study reported. Researchers said that the melting rate of the coastal Antarctic permafrost is now similar to the melt rate of permafrost at Arctic.
The permafrost in Antarctic was considered to be in equilibrium, meaning that it did melt and refreeze, but its mass remained the same. The regions experienced a cooling trend in the past decade and now have stable temperatures.
However, researchers have...

Nature World News: A vast water supply stored deep beneath the Sahara Desert thought to be a relic of ancient times is actually being resupplied each year, according to a new study published in the the journal Geophysical Research Letters. But the rate of resupply does not meet or exceed water demand, which poses long-term water challenges for the future.
The northern Sahara aquifer system extends across an area nearly double that of mainland France and is thought to hold more than 30,000 cubic kilometers of water...

Posted by Nature World News: None Given on July 11th, 2013
Nature World News: Trees are using water more efficiently now than they did two decades back, according to a new study from Harvard University and the U.S. Forest Service.
Researchers said that increased levels of carbon dioxide along and lower levels of water in many parts of the world have increased the efficiency of water usage in trees.
Plants use carbon dioxide from the atmosphere via a process called photosynthesis, where they lose water through leaves. The ratio of water loss to fixed carbon is important...

Posted by Nature World News: None Given on July 10th, 2013
Nature World News: To live on a warmer earth in the future, many vertebrates would have to evolve about 10,000 times faster than they have in the past, according to a new study.
Animals and plants adapt to survive. But, to match - up with the current changes in the environment, they'd have to evolve much faster than they do now. The study was conducted by a team of researchers led by John J. Wiens, an ecologist from University of Arizona.
According to a recent International Union for Conservation of Nature, about...

Posted by Nature World News: None Given on July 8th, 2013
Nature World News: Near the Maine border, a runaway train likely carrying hundreds of thousands, if not millions, of gallons of crude oil derailed Saturday and crashed into a downtown area in the Canadian town of Lac-Mégantic, Québec, causing death, destruction and untold environmental damage.
At least 40 people are missing and five are confirmed dead. A large swath of the town is destroyed and thousands were forced to evacuate.
As the community is still coming to terms with the tragedy, regional concerns over...

Posted by Nature World News: None Given on July 5th, 2013
Nature World News: Hector's dolphin is an endangered species of dolphins that's native to New Zealand and according o a new study, its population is declining due to amateur fishing in its habitat.
Akaroa harbor near Christchurch is a hotspot for tourists wanting to catch a glimpse of the dolphins or go swimming with them. However, in recent years fishing has led to many dolphins being caught in nylon fishing nets.
Hector's dolphins are the smallest and rarest dolphins in the world. The dolphin can fit in an...

Posted by Nature World News: None Given on July 4th, 2013
Nature World News: Toxic algal bloom at Lake Erie is expected to be worse this summer, according to NOAA and its research partners.
The National Oceanic and Atmospheric Administration said that algal bloom in the lake will probably be larger than last year, but won't be as severe as the record-high bloom of 2011.
A report published earlier in June had warned that algal bloom is likely to increase this year due to climate change that resulted in record-breaking rains in the region. The toxic blooms doesn't only...

Posted by Nature World News: None Given on July 3rd, 2013
Nature World News: According to a new study, the neonicotinoid pesticide can alter gene activity in honey bees.
Neonicotinoid pesticides are a class of pesticides that are taken up by the plant and expressed via nectar. Previous research conducted on the chemical neonicotinoids had found that it causes population decline in bumble bee colonies. Bees in Europe recently won against the pesticide after the EU decided to impose a two-year ban on the pesticide in Europe from April, 2013. A ban, that some people say,...
