In many taxa males become sterile at lower temperatures than females. In these species, females could buffer the negative effect on male fertility improving their own reproductive output by rejecting sterile males or mating with more than one male. However, this rescue is conditioned by the populations’ mating system and the mating behaviour of both sexes, which can also be disrupted by temperature. Unfortunately, most work has studied polyandrous species leaving a gap in our knowledge. Thus, understanding if and how monandrous species change their mating behaviour and/or mating system due to heat stress will bring important knowledge on the crucial topic of population persistence under climate warming. Here, we studied the real-time evolution of two bio-geographical distinct populations of a monandrous fruit fly (Drosophila subobscura) subjected to a global warming scenario. As such, we could test if selection and population history play a role in the ability to respond to temperature changes. Specifically, we aimed to assess: i) whether adaptation to a warming environment occurs; ii) the impact of high temperatures on male mating behaviour and fertility; and iii) the impact of reduced male fertility on female mating behaviour, fertility, and propensity to remate. We show that adaptation to warming conditions was population-specific and occurred with no evident costs. We also demonstrate that exposure to high temperatures leads to lower performance in males, affecting both behaviour and fertility. Importantly, these males are able to recover a functional mating behaviour through time, but not their reproductive output. Finally, we show that monandrous females remate after exposure to heat-stressed males and that this behaviour is advantageous for the reproductive output of the female leading to a total rescue of their reproductive performance in certain conditions. Ultimately, this project brings new insights on the effects of high temperatures on mating behaviour and fertility in a monandrous species and provide a model to assess how a shift from monandry to polyandry affects species at both the individual and the population levels.Rodrigues, Ana Leonor RapoulaSimões, Pedro Miguel Moraes Corado, 1978-Repositório da Universidade de LisboaMagalhães, Afonso Grandela Oliveira de2023-09-08T09:49:23Z202320232023-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10451/59177enginfo: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:RCAAP2023-11-08T17:08:11Zoai:repositorio.ul.pt:10451/59177Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T22:09:09.221248Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
