Tadpoles try to flee dangerous virus in their pond by growing much faster than normal
Researchers from the US studied the plasticity in growth and development of wood frog larvae in response to the emerging disease ranavirus, which can kill off the entire population of ponds. They showed that tadpoles in infected ponds speed up the rate of growth and progression through the immature stages. They hypothesize that this plasticity boosts their physical condition and hence immune response to ranavirus, and allows them to metamorphose earlier and escape infection.
