Long-term evolution experiments fully reveal the potential for thermal adaptation
Antunes, Marta; Grandela, Afonso; Matos, Margarida; Simões, PedroEvolutionary responses may be crucial in allowing organisms to cope with prolonged effects of climate change. However, a clear understanding of the dynamics of adaptation to warming environments is still lacking. Addressing how reproductive success evolves in such deteriorating environments is extremely relevant, as this trait is constrained at temperatures below critical thermal limits. Experimental evolution ...
Mate-choice copying accelerates species range expansion
Sapage, Manuel; Santos, Mauro; Matos, Margarida; Schlupp, Ingo; Varela, Susana A. M.Mate-choice copying is a type of social learning in which females can change their mate preference after observing the choice of others. This behaviour can potentially affect population evolution and ecology, namely through increased dispersal and reduced local adaptation. Here, we simulated the effects of mate-choice copying in populations expanding across an environmental gradient to understand whether it can...
Experimental Evolution in a Warming World: The Omics Era
Santos, Marta A.; Carromeu-Santos, Ana; Quina, Ana S; Antunes, Marta; Kristensen, Torsten N; Santos, Mauro; Matos, MargaridaA comprehensive understanding of the genetic mechanisms that shape species responses to thermal variation is essential for more accurate predictions of the impacts of climate change on biodiversity. Experimental evolution with high-throughput resequencing approaches (evolve and resequence) is a highly effective tool that has been increasingly employed to elucidate the genetic basis of adaptation. The number of ...
Evolution and Plasticity of Gene Expression Under Progressive Warming in Drosop...
Antunes, Marta; Santos, Marta A.; Quina, Ana S.; Santos, Mauro; Matos, Margarida; Simões, PedroUnderstanding the molecular mechanisms of thermal adaptation is crucial to predict the impacts of global warming. However, there is still a lack of research on the effects of rising temperatures over time and of studies involving different populations from the same species. The present study focuses on these two aspects, which are of great importance in understanding how organisms cope and adapt to ongoing chan...
Body size decline during thermal evolution is only detected at mild temperature
Antunes, Marta A.; Grandela, Afonso; Santos, Marta A.; Santos, Mauro; Matos, Margarida; Simões, PedroBody size is a key morphological trait that affects physiology and metabolism, as well as other relevant traits such as fertility and mating success. Some evidence points to a trend of shrinking body size with increasing temperature, but this is far from unequivocal. Here, we assess the evolution of body size under a warming environment in experimentally evolved Drosophila subobscura populations from two distin...
Mesa redonda: perspetivas sobre a educação em design gráfico
Matos, MargaridaO presente projeto tem como objetivo identifcar e enquadrar várias perspetivas sobre educação em design gráfco, pretendendo contribuir para um alargamento da discussão em torno deste tema. Procura abordar a educação, assim como a prática de design, como um processo colaborativo, criando espaços de partilha e discussão.Neste sentido, foi realizado um workshop que seguiu a organização de alguns exemplos de modelo...
Quality of life and well-being of adolescents in portuguese schools
Guedes, Fábio; Cerqueira, Ana; Gaspar, Susana; Gaspar, Tania; Moreno, Carmen; Matos, Margarida; Gaspar, SusanaThe quality of the school environment is associated with greater school involvement and academic success and improved levels of well-being/quality of life. In this sense, this study intends to explore the relationship between the quality of life of Portuguese adolescents and school. 8215 adolescents participated in this study, 52.7% of which were female, aged between 10 and 22 years and an average age of 14.36 ...
Microbes are potential key players in the evolution of life histories and aging...
Santos, Josiane; Matos, Margarida; Flatt, Thomas; Chelo, Ivo MMicrobes can have profound effects on host fitness and health and the appearance of late-onset diseases. Host–microbe interactions thus represent a major environmental context for healthy aging of the host and might also mediate trade-offs between life-history traits in the evolution of host senescence. Here, we have used the nematode Caenorhabditis elegans to study how host–microbe interactions may modulate th...
Past history shapes evolution of reproductive success in a global warming scenario
Santos, Marta A.; Antunes, Marta; Grandela, Afonso; Carromeu-Santos, Ana; Quina, Ana S.; Santos, Mauro; Matos, Margarida; Simões, PedroAdaptive evolution is critical for animal populations to thrive in the fast-changing natural environments. Ectotherms are particularly vulnerable to global warming and, although their limited coping ability has been suggested, few real-time evolution experiments have directly accessed their evolutionary potential. Here, we report a long-term experimental evolution study addressing the evolution of Drosophila th...
Detrimental impact of a heatwave on male reproductive behaviour and fertility
Grandela, Afonso; Antunes, Marta; Santos, Marta A.; Matos, Margarida; Rodrigues, Leonor R; Simões, PedroUnderstanding how heatwaves impact on different aspects of mating behaviour and fertility is getting increasingly important. In this context, laboratory fertility and mating experiments involving manipulation and exposure of insects to different thermal conditions are common procedures. To conduct such experiments practical methods such as dyes are needed for an easy, non-invasive discrimination of individuals....
