AIP Conference Proceedings 2025, 020002 (2018); https://doi.org/10.1063/1.5064875.0094-243X (print)1551-7616 (online)10.1063/1.5064875http://hdl.handle.net/2263/72261The long term properties, like co-existence and extinction, are usually determined by the demographics of the competing species or other competitive advantages. In this paper we consider the effect of conspecific support on the co-existence of species. We show that, even if the competing species have the same demographics and interaction, their co-existence can be destabilized by sufficient level of conspecific support. When considering large number of species the conspecific support destabilizes the co-existance equilibrium, thus producing a pattern of extinction and varied levels of existence. Upscaling the model to continuous space variable leads to model of pattern formation via local self-activation and lateral inhibition.en© 2019 AIP Publishing LLC.Conspecific supportCompetitive systemsPattern formationCo-existence of speciesCompeting speciesPostprint Article
