The effect of investigator disturbance on egg laying, chick survival and fledging mass of short-tailed shearwaters (Puffinus tenuirostris) and little penguins (Eudyptula minor)
Field-based animal researchers need to balance the potential adverse effects of their research activities against the benefits of research outcomes, but the data required to do this are often lacking. Assessing, and subsequently reporting the effects of researcher activities on wild animal populations can be difficult, so that studies to detect these effects sometimes lack […]
Acoustic convergence between two nocturnal burrowing seabirds- experiments with a penguin Eudyptuh minor and a shearwater Puffinus tenuirostris
The evolution of acoustic signals is influenced by environmental constraints. We studied two sympatric but unrelated seabirds: the Little Penguin Eudyptula minor and Short-tailed Shearwater Puffinus tenuirostris, to examine the degree to which similarities in their ecology had led to convergence in their calls. Both species nest in burrows in Southern Australia and, at night, […]
