Scientists from Virginia Tech the Woods Hole Research center and the University of California Santa barbara funded by NASA are collaborating with Brazilian scientists to explore the ecosystem consequences of the extreme droughts of 2005 and 2010 and the extreme flood
The research fills an important gap in our understanding of the vulnerability of tropical river-forest systems to changes in climate
Amazon floodplains and river channels--maintained by seasonal floods--promote nutrient cycling and high biological production and support diverse biological communities as well as human populations with one of the highest per capita rates of fish consumption said Castello.
The researchers will look at how the natural seasonality of river levels influences aquatic and terrestrial grasses fisheries
It is important that we understand how the Amazon river and ecosystem services such as fisheries are affected
because in some years they can almost double the amount of fish in the river that is available for fishermen and society.
and weight of the catch for 40 species. The hydrological data include daily water level measurements recorded in the Madeira Purus and Amazonas-Solimã es rivers.
and productivity of floodplain forests--those enriched by rising waters called whitewater river forests and nutrient-poor blackwater river forests.
Our research informs large river ecology globally because natural flowing rivers like the Amazon are rare these days
and most research to date being done in North america and Europe has focused on degraded systems Castello said Story Source:

An international research group led by Arizona State university professor Qiang Shawn Chen has developed a new generation of potentially safer and more cost-effective therapeutics against West Nile virus and other pathogens.
and protect mice against a lethal dose challenge of West Nile virus--even as late as 4 days after the initial infection.
The overarching goal of our research is to create an innovative yet sustainable and accessible low cost solution to combat the global threat of West Nile virus said Chen a researcher at Arizona State university's Biodesign Institute and professor in the Department
West Nile virus is spread by infected mosquitoes and targets the central nervous system. It can be a serious life-altering
or drug treatment against West Nile virus which has been widely spread across the U s. Canada Latin america and the Caribbean.
Secondly we've wanted to improve the delivery of the therapeutic into the brain to combat West Nile virus at the place where it does the greatest harm.
A couple of years ago his team demonstrated that their first candidate phu-E16 could neutralize West Nile infection
MABS target proteins found on the surface of West Nile virus . However this antibody was not to be able to accumulate at high levels in the brain.
Chen wanted to use this strategy to produce a more effective way to combat West Nile virus. In the new study they improved upon their phu-E16 design making half a dozen new variants that could for the first time lead to the development of MABS that effectively target the brain
and neutralize West Nile virus. Mice were infected with a lethal dose of West Nile virus and increasing amounts of a MAB therapeutic were delivered as a single dose the same day of infection.
In this case the therapeutic was administered 4 days after West Nile virus infection when the virus has already spread to the brain.
and makes possible neutralizing West Nile virus even after infection by a tetravalent MAB. The tetravalent MABS design will offer the researchers greater flexibility toward selection of disease tissue and antigen targets.

Watersheds are areas of land with streams and rivers that all drain into a larger body of water such as a bigger river a lake or an ocean.
It has disrupted the evenness of river flow resulting in alternate flooding and drought episodes an accelerated level of soil erosion as well as downstream sedimentation.

and it wouldn't go back into the river so river levels would go down and stress the fish.
So in examining that scenario ranchers could see how this feeds back and that's the iteration says Murphy.
For example stronger fluctuations must be expected in the outflows of rivers and the temperature of the groundwater may rise--with possibly negative consequences for drinking water quality.
Due to the changing streamflow in the rivers it will in future be necessary to be more economical with the use of water.

Local floodwater in the lower Cache River Valley south of the Mississippi river Diversion and Dike could not flow back into the Ohio river.

This is problematic because many rivers carry less water. If the increase in water use is limited agricultural production will not be lowered significantly.
