Hierarchical Metapopulation Dynamics of Two Aphid Species on a Shared Host Plant

These two theoretical papers build on the long-term field and laboratory studies on aphid metapopulation ecology and the role of predation for the induction of aphid winged dispersal morphs. Poethke et al. investigate the conditions under which predator-induced dispersal is an adaptive strategy for organisms with a metapopulation structure. Zheng et al. use field data collected in sites in Finland and Switzerland to model the hierarchical multiscale colonization-extinction dynamics of two aphid species living on tansy, Tanacetum vulgare using Bayesian inference.     «
