Wildlife Sanctuaries Along Coasts and Sea Level Rise

and has no comments yet.
A new report on the potential effects of climate change on NOAA's Olympic Coast National Marine Sanctuary uses existing observations and science-based expectations to identify how climate change could affect habitats, plants and animals within the sanctuary and adjacent coastal areas. It also outlines new management recommendations for the sanctuary, and sanctuary officials called it the first step toward addressing them. They also said the report issued by the sanctuary, Climate Change and the Olympic Coast National Marine Sanctuary: Interpreting Potential Futures, will provide a foundation of information and identify key issues facing the sanctuary.

How can Conservation Efforts help species adapt to climate change?

and has 1 comment.
As the climate changes, conservationists are divided over the most effective way to preserve animal and plant diversity because they cannot simply preserve the status quo. Ensuring species can shift to track the climate to which they are suited is a complex problem, especially when there are competing demands on land use. A simple prediction is that more habitat would help species to shift, but it is not obvious what the best spatial locations for habitat would be. A new study led by scientists at the University of York says that well placed habitat "stepping stones" would lead to faster range expansion than the equivalent amount and quality of habitat tacked onto existing sites. The result applies to situations where a species will have to cross gaps of several times the distance one individual can normally traverse, i.e. to species whose habitat is fairly rare.

Can Extreme Weather CONTRIBUTE to Climate Change?

and has 1 comment.
While experts debate whether extreme weather conditions such as this summer’s record rainfall can be explained by climate change, University of Leicester geographers are investigating whether the opposite is true – does extreme weather impact on climate change? To answer the question, a team of researchers from the Department of Geography and Centre for Landscape and Climate Research at the University of Leicester set up a new monitoring station in June to measure greenhouse gas emissions from drained and cultivated peatlands in the East Anglian Fens. They will make measurements over an extended period in order to record carbon emissions over a wide spectrum of weather conditions.

Giant Greenland Iceberg — Largest in the Northern Hemisphere — Enters Nares Strait

and has 1 comment.
ScienceDaily (Sep. 3, 2010) — ESA's (European Space Agency) Envisat satellite has been tracking the progression of the giant iceberg that calved from Greenland's Petermann glacier on 4 August 2010. A new animation shows that the iceberg, the largest in the northern hemisphere, is now entering Nares Strait -- a stretch of water that connects the Lincoln Sea and Arctic Ocean with Baffin Bay.

Marine Animals Suggest Evidence for a Trans-Antarctic Seaway

and has no comments yet.
As part of a study for the Census of Antarctic Marine Life (CAML), scientists from British Antarctic Survey (BAS) analysed sea-bed colonies of bryozoans from coastal and deep sea regions around the continent and from further afield. They found striking similarities in particular species of bryozoans living on the continental shelves of two seas -- the Ross and Weddell -- that are around 1,500 miles apart and separated by the West Antarctic Ice Sheet.

Trees May Have Killed Off the Mammoth

and has 1 comment.
A massive reduction in grasslands and the spread of forests may have been the primary cause of the decline of mammals such as the woolly mammoth, woolly rhino and cave lion, according to Durham University scientists. The findings of the new study challenge the theory that human beings were the primary cause of the extinction of mammals through hunting, competition for land and increased pressure on habitats. The research is part of the most comprehensive study to date of Northern Hemisphere climate and vegetation during and after the height of the last Ice Age, 21,000 years ago.

Deep, Open Ocean Is Vastly Under-Explored, Study Finds

and has no comments yet.
ScienceDaily (Aug. 3, 2010) — New research from the University of Sheffield has discovered that the deep open ocean, by far the largest habitat for life on Earth, is currently the most under-explored area of the sea, and the one we know least about. The research, published in the journal PLoS ONE, has mapped the distribution of marine species records and found that most of our knowledge of marine biodiversity comes from the shallow waters or the ocean floor, rather than the deep pelagic ocean- the water column deeper than the sunlit surface waters but above the sea bed.

First-of-Its-Kind Map Details the Height of the Globe’s Forests

and has no comments yet.
ScienceDaily (July 21, 2010) — Using NASA satellite data, scientists have produced a first-of-its kind map that details the height of the world's forests. Although there are other local- and regional-scale forest canopy maps, the new map is the first that spans the entire globe based on one uniform method.

How Music Training Primes Nervous System and Boosts Learning

ScienceDaily (July 20, 2010) — Those ubiquitous wires connecting listeners to you-name-the-sounds from invisible MP3 players -- whether of Bach, Miles Davis or, more likely today, Lady Gaga -- only hint at music's effect on the soul throughout the ages.

Arsenic Shows Promise as Cancer Treatment, Study Finds

and has no comments yet.
ScienceDaily (July 15, 2010) — Miss Marple notwithstanding, arsenic might not be many people's favorite chemical. But the notorious poison does have some medical applications. Specifically, a form called arsenic trioxide has been used as a therapy for a particular type of leukemia for more than 10 years. Now researchers at the Stanford University School of Medicine have shown that it may be useful in treating a variety of other cancers.
