All of the students hired at TMCC were Native American, thus increasing the diversity of students receiving scientific experience and training in agricultural science techniques. The PI presented the results of the research to local high school students and community members at the annual "College Awareness Day" event held at our college on October 20, An official website of the United States government.

Here's how you know. More information. Start date. End date. They examined a number of weather variables, including summer temperature, precipitation, winter severity, and drought. They also tested a long-standing hypothesis that the disease shows a wave-like pattern in causing large outbreaks in the first year and few cases subsequently due to a build-up of immunity in bird populations, which are the main hosts for the virus.

Kilpatrick said the links with drought were unexpected. In collaboration with Dr. Laura Kramer from the New York State Department of Health, his lab had developed a very careful method of mapping the influence of temperature on the biology of both the virus and the three different mosquitoes that are most important in transmitting the virus.

It's not yet clear how drought increases transmission of the virus, he said. Data from Colorado indicate that drought increases the fraction mosquitoes infected with West Nile virus, but not the abundance of mosquitoes. Drought might affect transmission between mosquitoes and birds by stressing birds or changing where they congregate.

Over the next three decades, drought is projected to increase in many regions across the United States due to increased temperatures, despite increases in precipitation in some of the same areas.

Model projections indicated that increased drought could double the size of future West Nile virus epidemics, but that outbreaks would be limited to regions that have yet to sustain large numbers of cases. These findings provide a tool to help guide public health efforts to regions most likely to experience future epidemics.

Horton and Ashfaq were formerly postdoctoral researchers at Stanford in Diffenbaugh's lab. Several studies have found that the EPA underestimates the amount of methane leaking from U. A new study finds emissions from deforestation, conversion of wild landscapes to agriculture, and other changes in land use worldwide contributed 25 percent of all human-caused emissions between and New research focused on interactions among microbes in water suggests fungal microparasites play a bigger than expected role in aquatic food webs and the global carbon cycle.
