Extinction or 'translocation' as impacts climate change increase?

ClimateWire: Climate change is altering the way some scientists are trying to save endangered plant and animal species from extinction. For nearly 100 years, conservationists have focused preservation efforts on maintaining species' historical ranges and reintroducing captive-bred species to boost dwindling populations. Now, some scientists are experimenting with a new approach. "What's changed over the years is we introduce [species] into areas where they have never been before," said Philip Seddon an...

Polarizing Beamsplitter features 200:1 extinction ratio.
2014-07-29 14:33:34| Industrial Newsroom - All News for Today
Splitting up S & P polarization of light with extinction ratio of Tp/Ts 200:1 and higher, Polarizing Beamsplitter Cube is suited for high-power laser applications up to 10 J/cm² pulsed and continuous wave. All entrance and exit faces are coated with thin film anti-reflection coatings to optimize overall performance of cube. Optical coatings operate at wavelengths from 200–2500 nm and can be customized to meet unique and critical requirements. This story is related to the following:Beamsplitters |

Antarctic fur seals, once hunted to near extinction, now face climate threat
2014-07-25 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: Climate change appears to be pulling the ecological rug out from under a once-stable population of Antarctic fur seals. Their numbers on a remote island in the South Atlantic are falling, even though an increasing proportion of survivors are displaying greater genetic variation a trait generally thought to boost an organism's ability to adapt to environmental stress. That's the pattern a pair of scientists has detected in a new study of the seal population, which researchers have been scrutinizing...
Emperor Penguins Marching Towards Extinction Due to Climate Change

Nature World: Contrary to what other recent reports have said, a new study by the Woods Hole Oceanographic Institution (WHOI) says that emperor penguins are in danger of dramatic declines by the end of the century, and marching towards extinction due to climate change. According to the authors, these iconic animals are "fully deserving of endangered status due to climate change," and are currently under consideration for inclusion under the US Endangered Species Act. Sea ice is vital to emperor penguin survival,...

Emperor penguins at extinction risk because of climate change
2014-06-30 13:19:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: Climate change will present a severe threat to the iconic emperor penguin, as temperatures rise and the Antarctic sea-ice that the species depends on disappears, a new study has warned. In a new report, researchers from around the world have urged governments to list emperor penguins the worlds largest penguin species -- as endangered, even though their numbers are expected to rise in the coming decades. Despite optimistic short-term forecasts, the study suggests that all of the 45 known...
