Thermal stress and fertility - how susceptible is the ejaculate?

A number of diverse factors threatens biodiversity with rising temperatures being one that is currently prominently debated. Ectothermic animals will be directly harmed by heat stress, as the surrounding temperature regime determines their bodily functions. Particularly male reproductive success is at risk as temperature stress is expected to be detrimental to the ejaculate. Seminal fluid proteins besides sperm are part of the ejaculate, are transferred at mating to the female and are vital to male reproductive success. In this research program, I want to investigate the susceptibility of male ejaculatory proteins and the tissue producing them, to heat stress and assess measures in place to protect it from heat damage using the fruit fly
