FIGURE 1.

Heatmap showing the relative abundance of all identified viral families at different examined systems. The matrix has taxa as rows and samples as columns. Columns were categorized into two types of water systems and arranged from lowest to highest average water temperature under each type of water system. 17 singleton rows were removed before matrix construction. White cells indicate absence of viral families. Green is assigned to the cell with the lowest value and red with the highest value. AZ, Amazon Rising; CR, Caribbean Reef; GLA, Warmer Great Lakes; GLB, Colder Great Lakes; OC, Oceanarium; STA, Stingray Touch before human contact; STB, Stingray Touch after human contact; WR, Wild Reef.
