Abstract The stability of isolated communities is determined by foodweb complexity.However, it unclear how local interacts with dispersal in multitrophic metacommunities to shape biodiversity patterns. Furthermore, metacommunity dynamics landscapes non-trivial and dynamic structures are less understood.vspace{8pt}\newline Objectives: We aim evaluate the influence stabilizing factors versus dispersalin determining sensitivity increasing site availabilityasynchrony. Additionally, we assess role complexity landscapestructure as modulating factors.vspace{8pt}\newline Methods: developed a model based on random matrices for communities, which linked stochastic over explicit landscapes. ran numerical simulations computed effect sizes temperature, self-limitation, ability, all pairwise combinations, landscape asynchrony. explored gradients species richness, connectance, number sites, modularity.Asynchrony among availability periods reduced \(\alpha\)-diversity rose \(\beta\)-diversity. Asynchrony increased \(\gamma\)-diversity at high rates. Bothlocal regional land-scape Local were more influential fewer sites andlower modularity. particularly composed complex foodwebs.This research offers insights into metacommunitiesin landscapes, providing valuable knowledge about interplay between andregional shaping ecological persistence. delve themechanisms underlying our results discuss potential extensions study.
