NewsTadpoles try to flee dangerous virus in their pond by growing much faster than normal
A new study shows that larvae of wood frogs respond to the presence of a deadly ranavirus by growing and maturing precociously. In response to ranavirus, tadpoles change their growth, development, and resource allocation, which may help them tolerate the energetic demands of infection or escape risky environments to avoid infection.
