World’s tiniest computer shows how South Pacific snail survived mass extinction

After an alien predatory snail was introduced to the South Pacific Society Islands in the 1970s, more than 50 native tree snail species were totally wiped out. Only a single native species, Partula hyalina, survived. Now, thanks to the world’s smallest computer, the Michigan Micro Mote, which scientists attached to the shell of the predator and to the leaves P. hyalina use for shelter, researchers know how. Data collected by the tiny computer showed P. hyalina can tolerate more sunlight than the alien predator, Euglandina rosea. Researchers shared their findings…
