Plastic responses of survival and fertility following heat stress in pupal and adult Drosophila virilis

open access: yesEcology and Evolution, 2021
The impact of rising global temperatures on survival and reproduction is putting many species at risk of extinction. In particular, it has recently been shown that thermal effects on reproduction, especially limits to male fertility, can underpin species
