Talk:Predator-prey model

I do not know enough of all the models in the article, although I do know enough of some of them [1]. But the lack of knowledge for some opf them makes it impossible to do a detailed review of the full text. However, I think that the text gets to quick to specialized, unless I am mistaken about the preferred level of complexity of the articles. KimvdLinde 20:29, 12 September 2006 (CDT)

Edward R. Dewey and cycles

I would like to see an additional note under preditor-prey model to mention that there are cases that might appear to be p-p but in fact are something different. Edward R. Dewey has identified examples, including the case of Canadian Lynx and (Snoeshoe?) rabbits. Each has a 9.6 year cycle in population with dramatic swings in population. There are two things that indicate that p-p is not the cause. The first is the lack of any phase difference in the cycle between the presumed preditor and prey. The other is that a number of other unrelated species from different habitats show the same 9.6 year cycle period. Additionally, there is a 9.6 year cycle found in ozone abundance that may be the real cause.

The is an error in the coexistence equilibrium for the Lotka-Volterra model; y = b/p, not b/d.
