The Rise and Fall of Penguin Populations
2014-06-12 21:33:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Over the last 30,000 years, a new study says, penguin populations have risen and fallen. Between the last Ice Age and up to around 1,000 years ago, penguins actually benefitted from the warming climates and retreating ice - though polar bears might disagree - suggesting that recently observed declines in penguin populations are the result of ice retreating too far and too fast. As detailed in the paper published in the journal Scientific Reports, an international team of scientists used a genetic...

High SCN populations thrive despite extremely cold winter
2014-04-08 06:00:00| Corn & Soybean Digest
GREENSBORO, N.C., USA, April 8, 2014 – The record low temperatures over the past few months may reduce some pest populations this spring, but university and Syngenta experts predict soybean cyst nematodes (SCN) will still threaten yields. “Many growers hope the cold weather we’ve been experiencing will help decrease pest populations,” said Dale Ireland, Ph.D., seed treatment technical product lead at Syngenta. “But it doesn’t affect SCN.” read more

Eastern chickadee populations moving fast in response to global warming
2014-03-08 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Summit Voice: Watching climate change is a little more subtle than just sitting around watching a thermometer, but sometimes even scientists are surprised at just how fast things are changing. A group of East Coast university researchers probably felt that way as they studied the breeding areas of Carolina and black-capped chickadees. Along a narrow zone in the eastern U.S., the two species interbreed, and that overlap zone is moving northward at 0.7 miles per year -- a full-on sprint by geological time standards....

Why Are Arctic Bird Populations Declining?
2014-01-24 18:23:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: On Coats Island, in northern Hudson Bay, thick-billed murres--members of the auk family--have been under assault on several fronts in recent years. Polar bears, faced with a sharp decline in the sea ice from which they hunt ringed seals, have retreated to the island and are eating the murres eggs. As the sea ice disappears, the murres now have to fly farther and work harder to get food that they normally find along the ice edges. And as temperatures around Hudson Bay rise, mosquitoes are hatching...

Carbapenemase-producing Germs in Livestock Populations
2014-01-15 01:00:00| ThePigSite - Industry News
GERMANY - Carbapenems are antibiotics authorised for the treatment of humans and which were categorised by the World Health Organisation as critically important antimicrobials for the treatment of humans. Reserve antibiotics of this kind are only supposed to be used when standard antibiotics no longer show any effects, i.e. for only restricted indications.
