Declining songbirds need forests to survive

From VT News

Before cutting down forest, land managers in drought-prone areas might first consider the birds in the trees.

According to a new study by biologists at Virginia Tech and the Smithsonian Migratory Bird Center, the offspring of a certain songbird, the wood thrush, are more likely to survive drought in larger forest plots that offer plenty of shade and resources.

These results were published Oct. 18 in The Auk: Ornithological Advances, a ...

Aquaculture: Mixing of farmed fish and their wild relatives could have adverse impacts on environment

From VT News

In Ghana, experts suspect that some fish farmers have started to raise unapproved, controversial strains of the Nile tilapia Oreochromis niloticus that have the ability to grow quickly on their farms.

A Virginia Tech graduate student seeks to establish which strains farmers are growing in the country, and whether these include the unapproved strains of genetically improved farm tilapia (GIFT).

“If it is confirmed that the GIFT strains are on the farms in ...

Postcards from the field: Gifty is collecting data on Nile tilapia from the Pra River in Ghana

By Gifty Anane-Taabeah

Wednesday, June 7, 2017

“I am currently lodging in Half-Assini, a border town between Ghana and our western neighboring country, Ivory Coast. I spent most of my day at Elubo, another border town about 45 minutes-drive from Half-Assini, in search of O. niloticus samples. Wednesdays are market days in Elubo and an opportune time to scout for wild-caught O. niloticus. This is especially important because Ghana shares the Tano River with Ivory Coast and the data generated will be useful for conserving ...

Strickland and Wepking: Agricultural antibiotics impact soil ecosystems

From VT News

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 ...
