I see no obvious reason to claim that one model or the other is more 'true'. They both demonstrate key concepts of population growth: exponential growth while rare, density dependence, and equilibrium density.Jörgen Ripahttp://www.blogger.com/profile/16338380487214737224noreply@blogger.comtag:blogger.com,1999:blog-6791792173245944806.post-44523095432554477642014-02-07T16:52:32.659+01:002014-02-07T16:52:32.659+01:00It's probably worth it to mention that the Ric...It's probably worth it to mention that the Ricker equation is not the exact discrete equivalent of the continuous logistic model. That's the Beverton-Holt model! The Ricker equation is actually an approximation that converges towards the continuous logistic model as the time step become smaller.Mehdi Cherifhttp://www.blogger.com/profile/07395062246892176631noreply@blogger.com
