Multiple equilibria & Klassresa

While writing the text for a proceedings paper from a talk I gave last November I have been reading a paper by Greg Dwyer in Nature (2004) and others about Gypsy moth population dynamics. Sometimes I don't understand what makes a paper attractive for publication in Nature. The paper by Dwyer is certainly interesting for me. It shows the importance of double processes - those that take place at low herbivore population levels and at high population levels. At low levels generalist predators may have the potential to make and impact while at high population levels a pest population needs enemies with a more intimate relationship (such as parasitoids and insect pathogenic virus). These are the kinds of multiple equilibria we found in our pinesawfly article. What Dwyer did was to add abiotic stochasticity and thereby added complexity which gave - not surprisingly - more complicated dynamics. I'd kind of like to explore this concept and can even see a possibility to try modelling Agricultural systems. Although the assumption of some regulating factor is difficult to deal with in Ag systems.
Ock Klassresan - från en bok av Ronny Ambjörnsson. Härlig beskrivning av arbetaregrabben som blir universitets professor. Ett nytt ord (för mig) : tetig. "Tetig var den som i något avseende avvek fron det normala." Och så till slut - om mentalitet: "Vi kan kalla den strävsamhetens och den ständiga verksamhetens mentalitet"
