Probing the pore of the auditory hair cell mechanotransducer channel in turtle.
TL;DR: Data provided by work characterizes the MET channel pore support a hypothesis regarding channel permeation and block that incorporates molecular dimensions and ion interactions within the pore.

TL;DR: The data show that female cognition can limit the evolution of sexual signal elaboration in túngara frogs, and both relative attractiveness and relative predation risk decrease because of how receivers perceive and compare stimuli.
How cricket frog females deal with a noisy world: habitat-related differences in auditory tuning
TL;DR: It is demonstrated that frogs from the more acoustically challenging Stengl habitat have enhanced both the sender and receiver portions of their communication system, evolving calls that transmit better and auditory filters that better eliminate noise.
Steady-state adaptation of mechanotransduction modulates the resting potential of auditory hair cells, providing an assay for endolymph [Ca2+].
TL;DR: A novel mechanism, likely universal among hair cells, is elucidated, in which mechanoelectric transduction and its calcium-dependent adaptation provide the depolarizing current to establish the hair cell resting potential.

The effects of spatially separated call components on phonotaxis in túngara frogs: evidence for auditory grouping.
TL;DR: It is shown that spatial cues play a limited role in grouping, as females group discrete components of the species’ complex call over wide angular separations, and once grouped the separate call components are weighted differently in recognizing and locating the call.
