Food web complexity and community dynamics
WebAbstract.-Food webs in nature have multiple, reticulate connections between a diversity of consumers and resources. Such complexity affects web dynamics: it first spreads the … WebApr 13, 2016 · Results. We begin with the simplest case of two local food webs (H N = 2, H P = 1).When the local food webs were isolated (M = 0), increasing the food-web complexity tended to destabilize the population dynamics (Fig. 1), consistent with earlier theoretical studies 3.When the two local food webs were coupled by migration (M > 0), …
