Effects of seismic operations on bowhead whale behaviour : implications for distribution and abundance assessments ...
Assessments of distribution and abundance are a common means of gauging impacts of anthropogenic activities on wildlife. However, the influence of behavioural responses on estimated numbers and distributions of animals is rarely considered within this context. I used behavioural data collected in th...
