Ice Age Extinctions: Skylark Holmes and Dr. Janet Watson Investigate,
"The Case of the Arboricidal Megaherbivores"

 
The Second-Order Predation Hypothesis of Pleistocene Extinctions: A System Dynamics Model
Earlier work:
Some of you may have already played with my simple extinction model, read my ideas in the mystery story with Skylark Holmes and Dr. Janet Watson -- "The Case of the Aboricidal Megaherbivores"
  New work testing Combinations of Hypotheses has been added and an expanded and updated model is available:
Pleistocene Extinctions (PEM)
Please talk back to me on either the old or the new work.
