Spatial Segregation of Interacting Species
TL;DR: It is suggested that the heterogeneity of the environment and the non-linear dispersive movements raise a spatial segregation of the populations of two similar and competing species and there is a possibility that this spatial segregation acts to stabilize the coexistence of twoSimilar species, relaxing the interspecific competition.
Journal ArticleDOI
Analyzing insect movement as a correlated random walk.
Peter Kareiva,Nanako Shigesada +1 more
TL;DR: A procedure for quantifying movement sequences in terms of move length and turning angle probability distributions is developed and it is shown this displacement formula can be used to highlight the consequences of different searching behaviors.
Journal ArticleDOI
Modeling stratified diffusion in biological invasions
TL;DR: A stratified diffusion model is constructed, which describes the dynamics of the size distribution of colonies created by long-distance migrants and provides an estimate of range expansion in terms of the rate of expansion due to neighborhood diffusion, the leap distance, and the colonization rate of long- distance migrants.
Journal ArticleDOI
Traveling periodic waves in heterogeneous environments
TL;DR: In this paper, a model for a single species population which propagates in a heterogeneous environment in a one dimensional space is presented, where two kinds of patches with different diffusivities and intrinsic growth rates are alternately arranged along the spatial axis.
