    To get a glimpse of a superpredator, just look in the mirror. Comparing hunting habits of mammals and fishes reveals humans as Earth’s most dangerous, oddball predator — one that targets adult prey in large numbers, a practice that can push populations into decline.

    Doctoring whole ponds as well as the tadpoles living in them has turned a disease hot spot back into a healthy home for wild toads. Majorcan midwife toads now flourish in mountain ponds once infected with the lethal chytrid fungus called Bd, says Trent Garner of the Institute of Zoology in London. The fungus attacks more than 700 amphibian species on five continents, shriveling or wiping out susceptible populations and even snuffing out species.

    A dinner plate piled high with food from plants might not deliver the same nutrition toward the end of this century as it does today. Climate change could shrink the mineral and protein content of wheat, rice and other staple crops, mounting evidence suggests.

    Accidental chair squeaks in a lab have tipped off researchers to a new world of eavesdroppers. Spiders don’t have eardrums, though their exquisitely sensitive leg hairs pick up vibrations humming through solids like web silk. Biologists thought airborne sounds more than a few centimeters away would be inaudible. But the first recordings of auditory nerve cells firing inside a spider brain suggest that the Phidippus audax jumping spider picks up airborne sounds from at least three meters away.
