Parasites alter how much effort they invest in survival versus reproduction, according to changes in their in-host population size. When population sizes plummet, parasites prioritise between-host transmission. However, smaller losses in number elicit reproductive restraint, which facilitates in-host survival and future transmission.

At night, gametocytes are twice as infective to mosquitoes, despite being less numerous in the blood. Enhanced parasite infectiousness at night interacts with mosquito circadian rhythms to increase sporozoite burdens fourfold when mosquitoes become infected from feeding during their rest phase.

Reveals that the malaria parasite Plasmodium chabaudi responds to host anaemia by increasing investment in transmission stages because, counterintuitively, host aneamia represents a better environment for parasite replication. Furthermore, evolutionary potential in form of genetic variation exists in the extent that parasite strains respond to changes in red blood cell resources.
