...Tanya Bojesen Lauridsen; Jakob Christensen-Dalsgaard ABSTRACT In most anuran amphibians, acoustic communication is of prime importance for mate localization and selection. The tympanic middle ear increases auditory sensitivity and directionality and is therefore expected to be favoured by natural...

Summary: The cutaneous pathogen Batrachochytrium dendrobatidis directly disrupts cutaneous ion regulation in amphibians by increasing skin permeability and reducing sodium transporter activity and abundance.

Many anuran signals contain two frequency peaks, each one matching the sensitivity of one of these two organs. We hypothesized that the processing of temporal characteristics of acoustic...

In anurans, landing typically involves the use of the forelimbs to decelerate the body after impact. Few detailed, quantitative descriptions of anuran forelimb kinematics during...

Reichert; Holland Galante; Gerlinde Höbel The visual ecology of nocturnal anurans is poorly understood, but there is growing evidence that vision plays a role in important behaviors such as mate choice. While several recent studies have demonstrated that females are responsive to visual...

Although the distance lunged varied, the synchronized movement of all four limbs always occurred. This behavior was first described by Sokol...

...Joshua J. Schwartz; Kenneth Huth; Raymond Hunce; Brandon Lentine SUMMARY Research has demonstrated that certain midbrain neurons of anurans ‘count’ interpulse intervals (IPIs). Some neurons fire after exposure to fewer intervals than do others. Counting can be reset to zero if an IPI falls outside...
