MARMAM,

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.

Best,

Killer whale predation on sea otters linking oceanic and nearshore
ecosystems.  Science 282: 473-476.
Provides initial evidence regarding the potential impact of killer whale
predation on sea otter populations in the Aleutian Islands.

megafaunal collapse in the North Pacific Ocean: An ongoing legacy of
industrial whaling?  Proceedings of the National Academy of Sciences

Suggests a mechanism that may have instigated changes in predation
pressure by killer whales.

Provides details on the energetic analysis and extends the predation
argument to Steller sea lions.

4. A side-by-side debate hosted by the Society of Marine Mammalogy
culminated in the following articles, which were to be published as a
point-counterpoint series in Marine Mammal Science.
