Short summary
We used simulations to analyze the dynamics of an intertidal predator and its prey, which also engage in non-trophic interactions. These interactions create strong dependencies between predator and prey, shifting dynamics from being driven mainly by new individuals arriving from external sources to an interplay between regional and local processes. Our findings highlight the importance of considering multiple interaction types to understand population and community structure.
