Abstract
All living organisms are permanently exposed to harmful parasites and pathogens. The immune system and with it sophisticated strategies arose to face challenging pathogens such as bacteria and viruses. One outstanding strategy is the transfer of immunity from mothers to offspring known as “trans-generational immune priming” (TGIP). Through the transfer of acquired immunological protection mothers can boost the immune defense of their offspring and facilitate resistance against bacteria present in the maternal environment. Commonly, TGIP is limited to females and was considered to be a maternal trait. Yet, in the sex-role reversed pipefish Syngnathus typhle fathers are closely connected to the embryos during male pregnancy over a placenta-like structure. This intimate physical connection between fathers and offspring may mechanistically facilitate additional paternal immune priming and provides an exclusive chance to study biparental investment into offspring immunity. In my thesis, I explored multi-generational biparental immune priming in the sex-role reversed pipefish S. typhle and discussed its evolutionary and ecological consequences as well as the mechanistic basis.
