Identification of a disturbance signal in larval red-legged frogs, Rana aurora
Article Abstract:
Red-legged frog larvae show antipredator behaviours including a rise in shelter use in response to chemical signals released from disturbed conspecifics. It appears that ammonium could be an element of the disturbance alarm signal of R. aurora. The release of disturbance signals could be a normal physiological process to which other individuals have become sensitive. Releasing ammonium in the presence of a predator could be the direct effect of a rise in metabolism needed for effective escape.

Sex recognition and mate choice by male western toads, Bufo boreas
Article Abstract:
Sex recognition and mate preference of male western toads, Bufo boreas, were investigated using field-based choice experiments. Results reveal that given a male and a female of equal sizes, male toads will not discriminate in amplexing but clasping another male does not last longer than three seconds because of a release call. When presented with female choices, male toads choose the larger potential mates.
