Nevertheless, if species persist long enough in sympatry, it may also drive the evolution of stronger pre-zygotic isolation (e.g., reinforcement), thereby completing speciation, or, in the presence of gene flow, it may instead select for weaker post-zygotic isolation, thereby reversing speciation. Determining what reproductive barriers (pre-zygotic and/or post-zygotic) are more likely to evolve in sympatry may thus allow better understanding the fate of interacting species. In this project, I used a pair of hybridizing genetically divergent colour form populations of the spider mite species Tetranychus urticae (green and red), which were previously shown to be fully postzygotically isolated. Following up to 69 generations of experimental evolution in sympatry or allopatry, I performed three different experiments to assess, respectively, pre-mating, post-mating pre-zygotic and early post-zygotic, as well as late post-zygotic barriers. I found that none of the tested reproductive barriers evolved during experimental evolution, but that green-form females evolved in sympatry differed from those evolved in allopatry. They had a lower fecundity, their offspring had a higher juvenile mortality, and their sex-ratio was more skewed towards females. Altogether, these results show that reproductive interference can quickly drive the evolution of a species’ reproductive traits and sex allocation. However, I also found that, conversely to our previous knowledge, late reproductive barriers were incomplete between all populations of the two forms. Therefore, genetic analyses would be necessary to determine whether the observed evolutionary responses result from selection, or are the by-product of gene flow in this system. Finally, these results also call for further research on other possible evolutionary responses, as well as on the ecological consequences of reproductive interference in natural populations.Zélé, FloreRodrigues, LeonorRepositório da Universidade de LisboaCunha, Miguel Lourenço do Carmo Ribeiro da2023-01-02T10:18:26Z202220222022-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10451/55551enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T17:02:37Zoai:repositorio.ul.pt:10451/55551Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T22:06:12.856540Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
