Because of the prevalence of memes, an abundance of research focuses on understanding how memes are shared and perceived within their online social environment and in what ways they differ from other modalities of online communication. In the present work, we present findings that suggest a relationship between how memes are introduced, shared, and diminish in online social systems and the behavior of biological species within an ecosystem. Framed by this perspective, we borrow ecological methodologies and concepts like resource availability, speciation, and competition to study human attention, creativity, and sharing dynamics (respectively) over a large collection of memes shared on Reddit. Specifically, we find that the population of memes has scaled almost exactly with the total amount of content created over the past decade. We find a consequence of limited human attention in the face of a growing number of memes is that the diversity of memes has decreased at the community level, albeit slightly, in the same period. A further consequence is that the average life span of memes has decreased dramatically, which is further evidence of an increase in competition and a decrease in a meme species\u2019 primary resource: human attention. From this work, we have found reasonable preliminary support for linking memes to species and, thus, meme research to ecological research. We believe that future research should work to strengthen this relationship and transfer more methodologies to meme and information research from ecology.<\/jats:p>","DOI":"10.1145\/3596213","type":"journal-article","created":{"date-parts":[[2023,5,13]],"date-time":"2023-05-13T11:14:51Z","timestamp":1683976491000},"page":"1-19","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Competition Dynamics in the Meme Ecosystem"],"prefix":"10.1145","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2929-5880","authenticated-orcid":false,"given":"Trenton W.","family":"Ford","sequence":"first","affiliation":[{"name":"College of William and Mary, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3994-8694","authenticated-orcid":false,"given":"Rachel","family":"Krohn","sequence":"additional","affiliation":[{"name":"Rose-Hulman Institute of Technology, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3164-2615","authenticated-orcid":false,"given":"Tim","family":"Weninger","sequence":"additional","affiliation":[{"name":"University of Notre Dame, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2023,10,26]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/0163443712467594"},{"key":"e_1_3_2_3_2","first-page":"830","volume-title":"Proceedings of the 14th International AAAI Conference on Web and Social Media (ICWSM\u201920)","author":"Baumgartner Jason","year":"2020","unstructured":"Jason Baumgartner, Savvas Zannettou, Brian Keegan, Megan Squire, and Jeremy Blackburn. 2020.
