Humans, wildlife, and the environment are all interconnected and play a role in one another’s health and well-being.
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.
By examining the effects of lead exposure in songbirds, more information will be known about how lead impacts learning and underlying neural networks in humans, since they share the same critical period of vocal learning.
