Fig. 2From: Decay of infectious adenovirus and coliphages in freshwater habitats is differentially affected by ambient sunlight and the presence of indigenous protozoa communitiesEffect of treatment variables on changes in F+ coliphage concentrations over time. Error bars represent standard deviation. Treatments: A (exposure to sunlight and indigenous microbiota including protozoa), B (exposure to only indigenous microbiota including protozoa), C (exposure to sunlight only), D (exposure to neither)Back to article page
