My Project

The impact of abiotic and biotic stressors on sexual selection  .


Organisms are subject to both natural and sexual selection, and they must balance their responses as they adapt to the new environmental conditions. During mate selection, males and females assess the fitness advantages of their mates based on different types of phenotypic traits. These traits are shaped by their underlying genes and environmental conditions. Most studies have neglected the role of climate change along with other anthropogenic stressors and biotic interactions as drivers of sexual selection. These stressors can affect both the survival and functional traits, thereby influencing the fitness of sexual traits. Establishing the link between different stressors and sexual selection may be a crucial step towards unraveling the underlying mechanisms that modulate sexual selection in nature. Furthermore, the exploration of this avenue will shed light on the implications of sexual selection for population viability facing environmental changes


Lab Work

Coming soon….



My main objective is to explore the underlying mechanisms of mate selection under different stressors to unravel how environmental changes shape sexual selection and its consequences on population viability, using insect as model organisms.
