Detrimental impact of a heatwave on male reproductive behaviour and fertility
Understanding 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. We report here a study measuring the effect of an extended heat stress applied to males on several parameters of mating behaviour and fertility of laboratory populations of Drosophila subobscura derived from two distinct European locations. We found highly detrimental effects of heatwave on mating behaviour—with longer (courtship and copulation) latencies and lower mating occurrence but no changes in mating duration—and fertility, with reduced fecundity and reproductive success. Furthermore, we also tested the efficacy of food dye as a marker for individual discrimination and mating occurrence. While food dye did not allow to infer the occurrence of a mating based on a transfer of coloration from male to female, it did not affect mating and fertility, attesting its utility has a method for discriminating individuals within mating experiments in the context of thermal studies. Importantly, despite the fact that the heatwave was only applied in males, we observed an impact on behaviour of females that mated with stressed males, by often refusing their nuptial feeding. This opens possibilities for further integrated research on the changes of female and male mating behaviour and fertility under different thermal scenarios.

Luso-arabic poetry: reviewing the concept
According to some Portuguese historians and ethnographers of the nineteenth century, as well as orientalists of the first decades of the twentieth, the Arabs did not have a starring role in Portuguese history. These narratives fit much of the arguments discussed by Edward W. Said in «Orientalism» (1978), as they represent the Arabs in a very derogatory way. After 1974, with the reinstatement of Democracy in Portugal, these Christian-nationalistic narratives lost some of their influence. Contemporary historians, archaeologists, and independent researchers considered the medieval Gharb a pinnacle of cultural sophistication, prosperity, and enlightenment. In the literary field, this thesis gained momentum in 1987, when Adalberto Alves published a collection of poems entitled «O Meu Coração é Árabe: a Poesia Luso-Árabe», with texts by thirty-nine Gharb al-Andalus poets. In this book – and others that followed – Alves complemented and amplified the controversial question of the Arabic influence on the forms and spirit of Iberian courtly poetry, namely the Galician-Portuguese lyric. Furthermore, Gharb al-Andalus is described as a “paradise lost” of tolerance and wisdom, radically opposed to the colonial mentality dominant before the 1974 Revolution. In this chapter, I will discuss the current use of the concept of Luso-Arabic poetry, presenting it as an example of “Counter-Orientalism” (Malette 2010). Firstly, I will show how the concept of Luso-Arabic poetry introduced a selective discourse about the Gharb al-Andalus through the exaltation of its poets and significant aspects of its culture. Secondly, I will explain how this concept paved the way for a historical narrative to build a more “authentic” Portuguese identity. Thirdly, I will look upon contemporary Portuguese poets inspired by Islamic poetry and philosophy. I will show that this subtle influence changes the idea of literary tradition by introducing new ways of understanding poetic writing.
