TL;DR: In this paper, Okubo et al. analyzed the effects of various kinds of spatially varying dispersal on the spatial structure of populations in a single species in a heterogeneous environment.

TL;DR: In this paper, it is shown that a trick introduced by H. R. Thieme to study a one-species integral equation model with a non-monotone======.................... operator can be used to show that some multispecies reaction-diffusion systems which are cooperative for small population densities but not for large ones have a spreading====== speed.

TL;DR: Characterised dispersal patterns of pine wilt disease in the southern part of Korea in four-year period based on the cross-correlation function and provided the map of spatial conformations that would be effective in addressing disease occurrence in both local and global aspects.

TL;DR: In the undisturbed area, environmental disturbances could generate spatially segregated distributions of species; in the disturbed area, species with higher dispersal abilities quickly invade and preferentially recover their population during the post-disturbance period, being temporarily relieved of competition from other species.

TL;DR: A new model for biological invasions in periodic patchy environments, in which long-range taxis and population pressure are incorporated in the framework of reaction-diffusion-advection equations, finds numerically that a population starting from any localized distribution evolves to a traveling periodic wave if the null solution of the RDA equation is locally unstable.
