Although it is listed in CITES Appendix II and there are population losses in mainland Ecuador, in Galapagos it is paradoxically a species of concern due to its invasive potential. Genetic studies can shed light on the invasion history of introduced species causing effects on unique ecosystems like the Galapagos. We analyzed nine microsatellite markers in <jats:italic>C.\u2009odorata<\/jats:italic> individuals from Galapagos and mainland Ecuador to describe the genetic diversity and population structure of <jats:italic>C.\u2009odorata<\/jats:italic> in the Galapagos and to explore the origin and invasion history of this species. The genetic diversity found for <jats:italic>C.\u2009odorata<\/jats:italic> in Galapagos (<jats:italic>H<\/jats:italic><jats:sub>e<\/jats:sub>\u2009=\u20090.55) was lower than reported in the mainland (<jats:italic>H<\/jats:italic><jats:sub>e<\/jats:sub>\u2009=\u20090.81), but higher than other invasive insular plant species, which could indicate multiple introductions. Our results suggest that Ecuador's northern Coastal region is the most likely origin of the Galapagos <jats:italic>C.\u2009odorata<\/jats:italic>, although further genomic studies, like Whole Genome Sequencing, Rad\u2010Seq, and\/or Whole Genome SNP analyses, are needed to confirm this finding. Moreover, according to our proposed pathway scenarios, <jats:italic>C.\u2009odorata<\/jats:italic> was first introduced to San Cristobal and\/or Santa Cruz from mainland Ecuador. After these initial introductions, <jats:italic>C.\u2009odorata<\/jats:italic> appears to have arrived to Isabela and Floreana from either San Cristobal or Santa Cruz. Here, we report the first genetic study of <jats:italic>C.\u2009odorata<\/jats:italic> in the Galapagos and the first attempt to unravel the invasion history of this species. The information obtained in this research could support management and control strategies to lessen the impact that <jats:italic>C.\u2009odorata<\/jats:italic> has on the islands' local flora and fauna.<\/jats:p>","DOI":"10.1002\/ece3.11723","type":"journal-article","created":{"date-parts":[[2024,7,10]],"date-time":"2024-07-10T20:38:36Z","timestamp":1720643916000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Preliminary insights of the genetic diversity and invasion pathways of <i>Cedrela odorata<\/i> in the Galapagos Islands, Ecuador"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2636-8084","authenticated-orcid":false,"given":"Martina","family":"Albuja\u2010Quintana","sequence":"first","affiliation":[{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales, Laboratorio de Biotecnolog\u00eda Vegetal Universidad San Francisco de Quito (USFQ)  Quito Ecuador"},{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales Universidad San Francisco de Quito USFQ  Quito Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2704-8288","authenticated-orcid":false,"given":"Gonzalo","family":"Rivas\u2010Torres","sequence":"additional","affiliation":[{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales Universidad San Francisco de Quito USFQ  Quito Ecuador"},{"name":"Gal\u00e1pagos Science Center Universidad San Francisco de Quito  San Cristobal Ecuador"},{"name":"University of North Carolina at Chapel Hill  Chapel Hill North Carolina USA"},{"name":"Estaci\u00f3n de Biodiversidad Tiputini, Colegio de Ciencias Biol\u00f3gicas y Ambientales Universidad San Francisco de Quito USFQ  Quito Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4954-8379","authenticated-orcid":false,"given":"Karla E.","family":"Rojas\u00a0L\u00f3pez","sequence":"additional","affiliation":[{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales, Laboratorio de Biotecnolog\u00eda Vegetal Universidad San Francisco de Quito (USFQ)  Quito Ecuador"},{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales Universidad San Francisco de Quito USFQ  Quito Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pacarina","family":"Asadobay","sequence":"additional","affiliation":[{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales, Laboratorio de Biotecnolog\u00eda Vegetal Universidad San Francisco de Quito (USFQ)  Quito Ecuador"},{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales Universidad San Francisco de Quito USFQ  Quito Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Walter","family":"Palacios\u00a0Cuenca","sequence":"additional","affiliation":[{"name":"Herbario Nacional del Ecuador (QCNE)\u2010Instituto Nacional de Biodiversidad  Quito Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00e9nesis","family":"Vinueza","sequence":"additional","affiliation":[{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales, Laboratorio de Biotecnolog\u00eda Vegetal Universidad San Francisco de Quito (USFQ)  Quito Ecuador"},{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales Universidad San Francisco de Quito USFQ  Quito Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7207-4568","authenticated-orcid":false,"given":"Maria de Lourdes","family":"Torres","sequence":"additional","affiliation":[{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales, Laboratorio de Biotecnolog\u00eda Vegetal Universidad San Francisco de Quito (USFQ)  Quito Ecuador"},{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales Universidad San Francisco de Quito USFQ  Quito Ecuador"},{"name":"Gal\u00e1pagos Science Center Universidad San Francisco de Quito  San Cristobal Ecuador"},{"name":"University of North Carolina at Chapel Hill  Chapel Hill North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,7,10]]},"reference":[{"key":"e_1_2_10_2_1","unstructured":"Asadobay P.(2019).Diversidad y conectividad gen\u00e9tica del cedro(Cedrela odorata Meliaceae)en Ecuador continental.
