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)
The class will meet once per week during Fall Semester 2017; Time TBD
Jacob Barney (email@example.com), Bryan Brown (firstname.lastname@example.org), David Haak (email@example.com), Erin Hotchkiss (firstname.lastname@example.org), and Scott Salom (email@example.com)
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 →
Pumping oxygen into the bottom waters of Southwest Virginia’s drinking water reservoirs can reduce treatment costs and help fish and other aquatic life, according to an interdisciplinary research team with the Global Change Center at Virginia Tech.
The team has installed oxygenation systems in three reservoirs that serve Roanoke and surrounding county residents — Carvins Cove, Falling Creek, and Spring Hollow — and are monitoring them to see how increased oxygen levels ...
A Virginia Tech graduate student is living in one of the hottest and driest countries in the world this semester so that he can study how climate change, land management, and other human-caused phenomena impact a community of animals known as the cavity guild.
Composed of birds, reptiles, mammals, amphibians, and invertebrates, the cavity guild, biologically speaking, is a group of animals that depend on holes and crevices in trees for their ...
Renowned climatologist James Hansen will visit Virginia Tech on March 10, 2017.
He will give a 4 p.m. lecture entitled “A Peaceful Revolution: Global Justice for Young People Requires a New Approach” in the Squires Student Center, followed by a question-and-answer period.
The event is free and open to the public as seating allows.
Hansen, who was among the first scientists to argue that the burning of fossil fuels is warming the planet, is the keynote speaker in the 40th Annual ...Read More →
In a powerful testament to the warming of the planet, two leading U.S. science agencies Wednesday jointly declared 2016 the hottest year on record, surpassing the previous record set just last year — which itself had topped a record set in 2014.
Average surface temperatures in 2016, according to the National Oceanic and Atmospheric Administration, were 0.07 degrees Fahrenheit warmer than 2015 and featured eight successive months (January through August) that were individually the warmest since the agency’s records began ...Read More →
The extinction crisis is far worse than you think. In all of Earth’s history, there have been five mass extinction events. You can see them charted here. Now, we’re on the verge of the sixth extinction. And three-quarters of all species could vanish. Imagine three out of four species that were common are gone. This is the first time humans have caused anything like this.Read More →
