Abstract in brief

The study used simulation modeling to explore how landscape mosaic structure affects traveling waves of insect outbreaks, specifically focusing on a model of the larch budmoth’s cyclic population dynamics across landscapes with different levels of habitat connectivity.
Traveling waves tend to originate from high-density habitat centers (foci) and spread outward, with the dynamics influenced by factors like immigration subsidies and overcompensatory density dependence, which cause populations to fluctuate more rapidly in connected habitats.
The findings support the idea that overcompensatory density dependence creates recurrent traveling waves starting from high connectivity areas, leading to cyclic outbreaks that propagate through the landscape.]
