While the evolutionary forces that form and maintain positive interactions have been investigated extensively, the influence of positive interactions on the ability of species to adapt to new environments is still poorly understood. Here, we use numerical simulations and theoretical analyses to study how positive interactions impact the likelihood that populations survive after an environment deteriorates, such that survival in the new environment requires quick adaptation via the rise of new mutants\u2014a scenario known as evolutionary rescue. We find that the probability of evolutionary rescue in populations engaged in positive interactions is reduced significantly. In cooperating populations, this reduction is largely due to the fact that survival may require at least a minimal number of individuals, meaning that adapted mutants must arise and spread before the population declines below this threshold. In mutualistic populations, the rescue probability is decreased further due to two additional effects\u2014the need for both mutualistic partners to adapt to the new environment, and competition between the two species. Finally, we show that the presence of cheaters reduces the likelihood of evolutionary rescue even further, making it extremely unlikely. These results indicate that while positive interactions may be beneficial in stable environments, they can hinder adaptation to changing environments and thereby elevate the risk of population collapse. Furthermore, these results may hint at the selective pressures that drove co-dependent unicellular species to form more adaptable organisms able to differentiate into multiple phenotypes, including multicellular life.<\/jats:p>","DOI":"10.1371\/journal.pcbi.1008732","type":"journal-article","created":{"date-parts":[[2021,2,18]],"date-time":"2021-02-18T15:35:52Z","timestamp":1613662552000},"page":"e1008732","update-policy":"https:\/\/doi.org\/10.1371\/journal.pcbi.corrections_policy","source":"Crossref","is-referenced-by-count":12,"title":["Positive interactions within and between populations decrease the likelihood of evolutionary rescue"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2409-7180","authenticated-orcid":true,"given":"Yaron","family":"Goldberg","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8476-8030","authenticated-orcid":true,"given":"Jonathan","family":"Friedman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2021,2,18]]},"reference":[{"key":"pcbi.1008732.ref001","doi-asserted-by":"crossref","first-page":"315","DOI":"10.1146\/annurev.es.13.110182.001531","article-title":"The Ecology of Mutualism","volume":"13","author":"DH Boucher","year":"1982","journal-title":"Annu Rev Ecol Syst"},{"key":"pcbi.1008732.ref002","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1086\/418432","article-title":"Our Current Understanding of Mutualism","volume":"69","author":"JL Bronstein","year":"1994","journal-title":"Q Rev Biol"},{"key":"pcbi.1008732.ref003","doi-asserted-by":"crossref","first-page":"119","DOI":"10.1016\/S0169-5347(02)00045-9","article-title":"Inclusion of facilitation into ecological theory","volume":"18","author":"JF Bruno","year":"2003","journal-title":"Trends Ecol Evol"},{"key":"pcbi.1008732.ref004","doi-asserted-by":"crossref","first-page":"306","DOI":"10.1007\/BF02912621","article-title":"Positive interactions among plants","volume":"61","author":"RM Callaway","year":"1995","journal-title":"Bot Rev"},{"key":"pcbi.1008732.ref005","first-page":"201","volume-title":"Marine community ecology","author":"JF Bruno","year":"2001"},{"key":"pcbi.1008732.ref006","doi-asserted-by":"crossref","first-page":"69","DOI":"10.1126\/science.296.5565.69","article-title":"Breeding Together: Kin Selection and Mutualism in Cooperative Vertebrates","volume":"296","author":"T.
