We examine whether evolution of the\nshared species acts as a coexistence mechanism and to what extent the answer\ndepends on the genetic architecture underlying trait evolution. In our models\nof exploitative and apparent competition, the shared species evolves its\ndefense or prey use. Evolving species are either haploid or diploid. A single\nlocus pleiotropically determines prey nutritional quality and predator attack\nrates. When pleiotropy is sufficiently antagonistic (e.g. nutritional prey are\nharder to capture), eco-evolutionary assembly culminates in one of two stable\nstates supporting only two species. When pleiotropy is weakly antagonistic or\nsynergistic, assembly is intransitive: species-genotype pairs are cyclically\ndisplaced by rare invasions of the missing genotypes or species. This\nintransitivity allows for coexistence if, along its equilibria, the geometric\nmean of recovery rates exceeds the geometric mean of loss rates of the rare\ngenotypes or species. By affecting these rates, synergistic pleiotropy can\nmediate coexistence, while antagonistic pleiotropy does not. For diploid\npopulations experiencing weak antagonistic pleiotropy, superadditive allelic\ncontributions to fitness can mitigate coexistence via an eco-evolutionary\nstorage effect. Density-dependence and mutations also promote coexistence.\nThese results highlight how the efficacy of evolution as a coexistence\nmechanism may depend on the underlying genetic architecture.","url_abs":"http://arxiv.org/abs/1609.05571v2","url_pdf":"http://arxiv.org/pdf/1609.05571v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"evolution-as-a-coexistence-mechanism-does","repo_url":"https://github.com/sebastian-schreiber/eco-evolutionary-coexistence","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
