Locations of sampling sites and images of Microcoleus-dominated mats. a Map of Eel River watershed showing location of samples collected in the Eel River watershed in August 2015. At sites represented by white circles and bold numbers, upstream and downstream samples were collected (designated with U and D in the text), while a single sample was collected at sites represented by black circles (designated with S in the text). Sites 2–4 were in close proximity to one another at a tributary confluence and are represented by a single circle. b Microcoleus-dominated mats in the Eel River. c Underwater photograph showing Microcoleus-dominated mat on a cobble. d Micrograph of Microcoleus trichomes (400×)
