AUSTIN, Texas — As the male túngara frog serenades female frogs from a pond, he creates watery ripples that make him easier to target by rivals and predators such as bats, according to researchers from The University of Texas at Austin, the Smithsonian Tropical Research Institute (STRI), Leiden University and Salisbury University.
A túngara frog will stop calling if it sees a bat overhead, but ripples continue moving for several seconds after the call ceases. In the study, published this week in the journal Science, researchers found evidence that bats use echolocation — a natural form of sonar — to detect these ripples and home in on a frog. The discovery sheds light on an ongoing evolutionary arms race between frogs and bats. (more…)
Cross a crow and it’ll remember you for years.
Crows and humans share the ability to recognize faces and associate them with negative, as well as positive, feelings. The way the brain activates during that process is something the two species also appear to share, according to new research being published this week.
“The regions of the crow brain that work together are not unlike those that work together in mammals, including humans,” said John Marzluff, University of Washington professor of environmental and forest sciences. “These regions were suspected to work in birds but not documented until now. (more…)
Pathogen leads to dehydration, other ill effects
The fungal infection that killed a record number of amphibians worldwide leads to deadly dehydration in frogs in the wild, according to results of a new study.
High levels of an aquatic, chytrid fungus called Batrachochytrium dendrobatidis (Bd) disrupt fluid and electrolyte balance in wild frogs, the scientists say, severely depleting the frogs’ sodium and potassium levels and causing cardiac arrest and death. (more…)
