Bovine babesiosis, or cattle fever, was once one of the worst diseases afflicting the U.S. livestock industry. Although the tick-borne parasite Babesia bovis was largely eradicated … Read more about NAU geneticist awarded $500,000 USDA grant to prevent tick-borne cattle fever
As part of the annual Undergraduate Expo, the Northern Arizona University Honors College will host an interdisciplinary climate change teach-in to encourage climate change conversations among faculty, staff, students and community members from disparate disciplines. The event will feature interdisciplinary talks and roundtables on climate change, emphasizing the importance of being scholarly, informative, practical, action-oriented, educational and discussion-based.
Presentations and roundtables will be on topics like teaching practices, research, science communication, community organization, direct action, infrastructure, vulnerable populations, local adaptation… Read more
When it comes to climate change, not all carbon is created equal. Among greenhouse gases, methane is 34 times more potent than carbon dioxide.
In the Arctic, where temperatures are rising twice as fast as anywhere else in the world, scientists want to understand the ratio of carbon dioxide to methane gas released by thawing permafrost—the frozen ground in that region. As the permafrost thaws, microbes wake up and begin digesting the newly available remains of ancient plants and animals… Read more
Sometimes what is all around us is the most difficult to see clearly.
Drylands occupy about 41 percent of Earth’s surface and support 38 percent of its population, but such expansiveness poses a challenge to understanding the effects of climate change on the soil fungi and bacteria that are key to how those lands function.
Getting some perspective required gathering soil samples from 80 global sites through the contributions of research groups around the world. Matthew Bowker, assistant professor of forest… Read more
As scientists measure the speed and effects of carbon release from thawing Arctic permafrost, one group is studying the metabolism of old carbon that has been stored in soils but is now being released by a warming climate.
Estimates put the amount of carbon stored in soils of the permafrost region to be almost twice the amount present in the atmosphere. Billions of tons of organic carbon from plants and animals have been stored in these frozen soils for hundreds… Read more
To improve the accuracy of complex computer modeling, climate researchers in the Arctic are turning to natural features a little more in tune with longer time scales: glaciers and the lakes they feed.
The contrast between high-speed computing and slow-moving natural systems reflects the landscape of climate research in a region protected by its isolation, yet sensitive to change.Read more
In forests around the world, drought leaves a legacy that endures even after the rains return.
Three Northern Arizona University researchers contributed to a study published this week in Science that showed surviving trees took an average of two to four years to recover and resume normal growth rates after droughts ended.
The finding runs counter to climate models that assume instant recovery, said George Koch, a professor in NAU’s Center for Ecosystem Science and Society. Koch focused on project design… Read more
