In a cow pasture near Shawnee in central Oklahoma, Kirk Wilson parks his work truck, grabs a harness, and prepares for a 30-foot climb.
“We’re changing the sensor at the top of the tower that measures the wind direction,” explains Wilson, a burly meteorological electronics technician with a big beard and a booming laugh.
On the ground, another tech uses a GPS receiver to make sure the sensitive instrument is properly aligned before it’s tightened in place.

In Bangladesh, low-lying and vulnerable to yearly flooding, farmers are shifting from raising chickens to raising ducks. Ducks can swim.
In the Philippines, where half the mangrove forests have been lost to development, biologists are replanting the trees to recreate nature’s protective coastal shield against deadly typhoons. The gnarled tangle of mangrove roots slows the movement of ...
When a huge floating gyre of plastic waste was discovered in the Pacific in the late 1980s, people were shocked. When whales died and washed ashore with stomachs full of plastic, people were horrified. When photographs of beaches under knee-deep carpets of plastic trash were published, people were disgusted.
Though some of it came from ships, most, presumably, was from land. ...
April 10, 2018 | Leah R. Johnson, an assistant professor in the Department of Statistics, part of the Virginia Tech College of Science, is using a $700,000 National Science Foundation CAREER grant to improve mathematical and statistical models to help fight deadly diseases.
The vector-borne diseases that Johnson is targeting include dengue in humans and huanglongbing, commonly known as citrus greening, in fruit trees. The dengue virus, according to ...Read More →

How do you study the world’s more widespread predator? By spying from space.
When a team of researchers set out to see how prevalent industrial fishing was around the world—who was fishing where and when—they were met with a dearth of information.
The conversion of tropical forests to crop and pastureland has long been a concern for scientists, as forest loss can lead to decreased rainfall, increased droughts, and degraded freshwater ecosystems. A new study points to another unexpected consequence: changes in fish production.
The study, led by Leandro Castello, assistant professor of fisheries in Virginia Tech’s College of Natural Resources and Environment, explores how deforestation along the Amazon River floodplain affects fisheries yields. The study was published online Dec. ...Read More →
Aquatic invertebrates found in mountain streams — crayfish, stoneflies and mayflies, among others — are important to ecosystems because they are part of the natural food web and are often used by state agencies as indicators of freshwater health.
Soon, land managers will be able to track the behaviors of these invertebrates using a computer model developed by a research team that includes Virginia Tech aquatic ecologist, Bryan Brown.
The model, supported by a National Science Foundation grant, ...Read More →

AUG 2 2017 | Spend enough time driving through Central Appalachia, and you’ll see lush green mountain ranges brimming with diverse plant and animal species. Within those mountains, though, you can also find some of the most dramatic human health disparities in the nation.
Past studies going back to the 1970s indicate heightened incidences of ...
A new team-taught course will be offered this fall at Virginia Tech!
The Science and Policy of Invasions (GRAD 6984; Special Topics; 3 credits)

Invasive species are one of the five elements of global change that shape ecosystem structure and function worldwide. This course will take a “deep ...
There’s an unplanned experiment going on in the northern Rocky Mountains. What’s happening is that spring is arriving earlier, and it’s generally warmer and drier than usual. And that’s messing with some of the fish that live there.
The fish is the iconic cutthroat trout. It’s a native North American fish that thrives in cold, small streams. Explorer Meriwether Lewis of Lewis and Clark Expedition fame was among the first ...Read More →
Jon’s GLEON Fellowship Program trains small cohorts of graduate students from around the world to analyze large and diverse data sets, operate effectively in diverse international teams, and communicate science to researchers, the public, and managers. In addition to taking part in three international workshops, Jon ...Read More →
Brian Richter, the chief scientist for the Global Water Program of The Nature Conservancy, will visit Virginia Tech on April 7. He will give a 4 p.m. distinguished lecture entitled “Chasing Water in a Rapidly Changing World” at the Lyric Theatre, followed by a question and answer period and book signing.
Richter has been a global ...Read More →
Manure from cattle administered antibiotics drastically changes the bacterial and fungal make-up of surrounding soil, leading to ecosystem dysfunction, according to a Virginia Tech research team.
The team analyzed soil samples from 11 dairy farms in the United States and found that the amount of antibiotic resistant genes was 200 times greater in soil near manure piles compared with soil that wasn’t.
Furthermore, microbes with greater antibiotic resistance showed higher stress levels. Their findings were published March 29 in ...Read More →
The documentary film “Between Earth and Sky: Climate Change on the Last Frontier” will be screened at 7 p.m. on April 12 at The Lyric Theatre in downtown Blacksburg. David Weindorf, the film’s executive producer, will be on hand to introduce the movie to a Blacksburg audience.
Sponsored by the Global Change Center at Virginia Tech and the Department of Crop and Soil Environmental Sciences at Virginia Tech, the event is free and open to the public. Among ...Read More →
