Natural variation as well as human impacts can alter the light environment in lakes in ways that affect aquatic host‐parasite interactions. In laboratory infection assays, Rogalski and Duffy (2020) determine that the bacterial parasite Pasteuria ramosa adapts to solar radiation by increasing its transmission potential to its zooplankton host, Daphnia dentifera . Local adaptation to light can allow P. ramosa spores to retain their infectivity following light exposure. Future work should determine the underlying drivers of P. ramosa light adaptation and how adaptation might alter ecosystem dynamics.
