Ocean Dead Zones Could Approach Mass Extinction Levels

The future of Earth's oceans is beginning to look a lot like a mass extinction, according to new research. Today, approximately 2 percent of the seas qualify as 'dead zones' -- naturally desolate, oxygen-starved regions where higher life forms either can't breathe or find enough food to subsist. But according to a computer simulation out to 100,000 years in the future, those zones could engulf one-fifth of the seas within a few millennia if humans don't change their carbon-emitting ways soon. Gary Shaffer of the University of Copenhagen in Denmark led the study published yesterday in the journal Nature Geoscience, which examined the oceans' long term reaction to several emissions and warming scenarios.

A farmed elk from an Olmsted County herd has tested positive for Chronic Wasting Disease, the Minnesota Board of Animal Health confirmed Monday. The case is the sixth involving CWD in Minnesota farmed elk or deer and the first since 2006. In 2002 and 2003, three central Minnesota elk were found to have the disease. In 2006, it was found in two white-tail deer on a western Minnesota farm. Officials said they are trying to determine the source of the infection and whether other elk or deer may have been exposed. The brain stem and lymph nodes from the 7-year-old female elk were tested recently at the U.S. Department of Agriculture's National Veterinary Services Laboratory in Ames, Iowa.
Predicting the future spread of infectious-disease vectors

As global warming raises concerns about potential spread of infectious diseases, a team of researchers has demonstrated a way to predict the expanding range of human disease vectors in a changing world. Researchers from Australia and the University of Wisconsin-Madison have identified the key biological and environmental factors constraining a population of the dengue fever vector, the mosquito Aedes aegypti. In a study publishing online Jan. 28 in the British Ecological Society's journal Functional Ecology, they report that climate changes in Australia during the next 40 years and the insect's ability to adapt to new conditions may allow the mosquitoes to expand into several populated regions of the continent, increasing the risk of disease transmission.
