Songbirds exposed to lead-contaminated water show telltale signs about human impacts

Songbirds exposed to lead-contaminated water show telltale signs about human impacts Published Thursday, Feb. 4, 2021, 11:14 am Join AFP s 100,000+ followers on Facebook Purchase a subscription to AFP | Subscribe to AFP podcasts on iTunes News, press releases, letters to the editor: augustafreepress2@gmail.com (© Xavier MARCHANT – stock.adobe.com) Humans, wildlife, and the environment are all interconnected and play a role in one another’s health and well-being. Sentinel species, such as birds, are good indicators of environmental health, and they can send subtle warning signs that humans may be in danger next. In an experimental exposure study, Kendra Sewall, an associate professor of biological sciences in the College of Science, and a diverse team of scientists and students have found that lead levels like those reported in Flint, Michigan, can interfere with the neural mechanisms of vocal development of songbirds and affect mate attraction.

Researchers Find 635 Million-Year-Old Fungi-like Microfossil

Andrew Czaja of University of Cincinnati When you think of fungi, what comes to mind may be a crucial ingredient in a recipe or their amazing ability to break down dead organic matter into vital nutrients. But new research by Shuhai Xiao, a professor of geosciences with the Virginia Tech College of Science, and Tian Gan, a visiting PhD student in the Xiao lab, highlights yet another important role that fungi have played throughout the Earth s history: helping the planet recover from an ice age. A team of scientists from Virginia Tech, the Chinese Academy of Sciences, Guizhou Education University, and University of Cincinnati has discovered the remains of a fungi-like microfossil that emerged at the end of an ice age some 635 million years ago. It is the oldest terrestrial fossil ever found. To put it into perspective, this microfossil predates the oldest dinosaurs about three times over.

Virginia Tech hosts State of the University, prepares for students to return

Virginia Tech hosts State of the University, prepares for students to return Thousands of Hokies will return to Blacksburg next week Tags:  BLACKSBURG, Va – With the start of the spring semester just days away, Virginia Tech President Tim Sands says employees are working around the clock to welcome students back to Blacksburg. “We are building on what we learned in the fall as a ramp-up of our testing for the spring with an emphasis on mandatory random prevalence testing of students and surveillance testing of high contact employees,” Virginia Tech President Tim Sands said. During his state of the university speech Wednesday, Sands explained that Virginia Tech is facing a $60 million dollar loss stemming from the pandemic.

Fatal Attraction: Bats With White-Nose Syndrome Prefer Suboptimal Habitats Despite Consequences

Fatal Attraction: Bats With White-Nose Syndrome Prefer Suboptimal Habitats Despite Consequences - 8:50 am Bats with white-nose syndrome roosting in the warmest sites have been hit particularly hard, according to a new study by researchers at Virginia Tech. Courtesy/Virginia Tech A research team uses a swab to measure the fungal loads on each individual bat and a laser thermometer to measure the roosting temperature of the rocks next to each bat. Courtesy//Virginia Tech By KENDALL DANIELS Virginia Tech Since 2006, a fungal disease called white-nose syndrome has caused sharp declines in bat populations across the eastern United States. The fungus that causes the disease, Pseudogymnoascus destructans, thrives in subterranean habitats where bats hibernate over the winter months.
