Conditions experienced prenatally, by modulating developmental processes, have lifelong
effects on individual phenotypes and fitness, ultimately influencing population dynamics. In …

Many male signallers convey information to female receivers in multimodal courtship
displays. While much is known about how males vary in terms of signalling, variation in …

of the “problems” in working with aquatic animals is that they are not nearly as easy to …

Noise pollution is expanding at an unprecedented rate and is increasingly associated with
impaired reproduction and development across taxa. However, whether noise sound waves …

The auditory brainstem response (ABR) was recorded in adult budgerigars (Melopsittacus
undulatus) in response to clicks and tones. The typical budgerigar ABR waveform showed …

Contrast sensitivity (CS) is the ability of the observer to discriminate between adjacent
stimuli on the basis of their differences in relative luminosity (contrast) rather than their …

Parrots of the Wild explores recent scientific discoveries and what they reveal about the lives
of wild parrots, which are among the most intelligent and rarest of birds. Catherine A. Toft …

Anthropogenic noise can have serious implications for animals, especially when they
communicate acoustically. Yet, the impacts of noise may depend not only on noise …

Although lizards have highly sensitive ears, it is difficult to condition them to sound, making
standard psychophysical assays of hearing sensitivity impractical. This paper describes non …

In recent years, the impact of prenatal sound on development, notably for programming
individual phenotypes for postnatal conditions, has increasingly been revealed. However …
