Should Citrus Farmers Use Antibiotics to Combat Greening Disease?

By Maryn McKenna at National Geographic

When you hear about antibiotic use in agriculture it is almost always about the kind of routine everyday use in livestock that the Food and Drug Administration is trying to eliminate. But there’s another type of antibiotic use in agriculture. It may be less known, but it’s poised to generate just as much controversy: spraying the drugs on citrus trees.

Bird feeders may contribute to the spread of disease in wild songbird populations

From VT News

BLACKSBURG, Va., Sept. 17, 2015 – Wild songbirds that prefer to eat at bird feeders have an increased risk of acquiring a common eye disease. In turn, these birds also spread the disease more quickly to their flock mates, according to an international research team led by Virginia Tech scientists.

The researchers found that this feeding preference, rather than its social position in the flock, as previously thought, was more likely to result in a ...

The first 21 days of a bee’s life: a Ted Talk photo journey

We’ve heard that bees are disappearing. But what is making bee colonies so vulnerable? Photographer Anand Varma raised bees in his backyard — in front of a camera — to get an up close view. This project, for National Geographic, gives a lyrical glimpse into a bee hive — and reveals one of the biggest threats to its health, a mite that preys on baby bees in the first 21 days of life. With his incredible ...

Research in the Belden Lab could lead to protective probiotics for amphibians

Press Release from the American Society of Microbiology
Washington, DC – July 30, 2015

In research that could lead to protective probiotics to fight the “chytrid” fungus that has been decimating amphibian populations worldwide, Jenifer Walke, PhD, a postdoctoral researcher at Virginia Tech University, Blacksburg, and her collaborators have grown bacterial species from the skin microbiome of four species of amphibians. The research appears July 10 in Applied and Environmental Microbiology, ...

IGC Fellows Estrada and Medina work on issues that address declining species worldwide

Video: In the rainforests of Central America, a research team studies a skin disease that may be the tipping point for amphibian life on the planet.

From VT News

As the clock ticks, populations of endangered species decline and threaten the functioning of healthy ecosystems.

Pollution, hunting, habitat degradation, climate change, and invasive species have dealt blows to global biodiversity. Climate change alone is putting one in six species on Earth at risk of extinction, according to a meta-analysis of 131 ...

Postcards: Laura Schoenle arrives in Ontario for field season

April 8, 2015

“Hi! I just arrived at the Queen’s University Biological Station (QUBS) in Elgin, Ontario, and while we’re still in the midst of winter up here, the migratory birds are already returning. My personal favorite is the red-winged blackbird, and they are singing right now, even as the snow falls…

My research focuses on the role of hormones in shaping how birds cope with disease.  I have two exciting experiments planned for this summer, and each will become chapters in my Ph.D. dissertation. In ...

Lisa Belden’s research on Bd reveals new information about amphibian disease resistance

From VT News

BLACKSBURG, Va., March 26, 2015 – A team of scientists including Virginia Tech researchers is one step closer to understanding how bacteria on a frog’s skin affects its likelihood of contracting disease.

A frog-killing fungus known as Batrachochytrium dendrobatidis, or Bd, has already led to the decline of more than 200 amphibian species including the now extinct-in-the-wild Panamanian golden frog.

In a recent study, the research team attempted to apply beneficial bacteria found on the skin of ...

Laura Schoenle’s research featured on Virginia Water Radio

From Virginia Water Radio for the week of March 30, 2015.

Transcript:

“This week, we feature a mystery sound mix. Have a listen for about 15 seconds, and see if you can guess what water-related bird disease is the focus of research related to these sounds.

If you guessed avian malaria, you’re right! You heard Red-winged Blackbirds, a mosquito’s buzz, and the buzz of an electric-power station. All relate to aspects of research by Virginia Tech Biological Sciences graduate student ...

Facing my fears, headlamp-on in Panama

By Lindsay Key, Fralin Life Science Institute Communications Officer

This is Lindsay Key’s second blog report from Panama. She is traveling over spring break with Angie Estrada and Daniel Medina, who are conducting field research near Gamboa.

One thing is for sure: field research is messy. Not just in the sense that nature is full of mud and water and bugs, but in terms of logistics. You have to learn to expect the unexpected.

On Wednesday, we leave Gamboa bright and ...

Postcards from the field: traveling with VT graduate student researchers in Soberania National Park

We’re going on a frog hunt!

by Lindsay Key, Fralin Life Science Institute Communications Officer

Hello from the extremely bumpy backseat of a white pick-up truck that is barreling down a washed-out pothole-ridden trail known as Pipeline Road (left, below) in Gamboa, Panama. This is a famous road— known for its wildlife viewing capabilities and accessed by thousands of scientists around the world who come to study and work at the nearby Smithsonian facility in the tiny research town of Gamboa.

It ...
