Over the past ten years there has been considerable debate regarding the
role of killer whale predation on marine mammal declines in the North
Pacific.  The publication series is an excellent example of scientific
debate that should be of interest to both the scientific and
non-scientific communities.  The following list of publications provides
some of the key issues and the opportunity for comparative analysis. 
Seminar groups may find the series fodder for extended discussions.
