Metapopulations dynamics, populations fluctuations, and stochastic dispersal

Fluctuating connectivity may not be the only mechanism behind populations’fluctuations. Three major hypothesis link pattern of population’s fluctuations to fluctuating environmental conditions, interactions among or between species, or/and to dispersal. While, These hypothesis have been studied alone or in pairs in order to understand the mechanisms and contribution of each to population’s fluctuations. I revisit the paradigm of population’s fluctuations using a different prospective, I study the effects of varying environmental conditions on dispersal, and how it affect metapopulation dynamics when considering species interactions.
