To Elude Bats, A Moth Keeps Its Hearing In Tune:

Current understanding of the co-evolution of bats and moths has been thrown into question following new research reported in the journal Current Biology. Dr James Windmill from the University of Bristol, UK, has shown how the Yellow Underwing moth changes its sensitivity to a bat's calls when the moth is being chased. And in case there is another attack, the moth's ear remain tuned in for several minutes after the calls stop.

BATS use sonar, or echolocation, to navigate complex environments, and also to forage and then accurately pinpoint the flying insects on which they prey. Insects in turn have evolved various counter-measures to evade capture. Some species have ears which are in tune to the echolocation signals,…
I'm between books right now. As an inveterate reader, this makes me feel antsy and unmoored. I want to get my hands on something good--and specifically, I'm thinking of going on a science-book spree. The science-books-for-laypeople genre is one that I haven't explored as much as I would like. (…
Echolocation - or biological sonar - can be thought of as an auditory imaging system that is used by organisms in environments where vision is ineffective. It involves the emission of vocalizations by the animal, and the detection of the echoes of those sounds, which are used to produce three-…
