## Communicated by M. Grinfeld A single population growth model with stage-structured and state-dependent impulsive control is proposed. By using the PoincarΓ© map and the analogue of PoincarΓ©'s criterion, we prove the existence and the stability of positive order-1 or order-2 periodic solution. Mo

AbstractmDeclines in species richness or population are primarily attributed to habitat destruction and fragmentation. Can we avoid the local extinction of species with stage-structure in some patches by building some corridors between the patches and controlling the dispersal rates? A conservation

A model of host-parasitoid-hyperparasitoid is considered with ratio dependence between parasitoid and hyperparasitoid. First, the conditions for local stability and increasing host fitness due to the effect of hyperparasitism are deduced. Next, we study the effects of stochastic environmental fluctu

A simple metapopulation lattice model of two competing phenotypes is presented, where one phenotype reacts more sensitively to overcrowding by migrating to neighbouring local habitats. The sensitivity is formulated by means of a threshold density of the subpopulations, above which dispersal is trigg
