Educational aid or CurriculumThe Salmon River Coloring BookZabrecky, J; Elliott, TThe Salmon River Coloring Book documents patterns of algal succession found on the Salmon River in northern California (a tributary to the larger Klamath River) which includes diatoms, cyanobacteria, and green algae. Algal groups are presented in coloring pages as both (1) macroscopic (i.e., visible to the human eye) forms and (2) microscopic (i.e., requiring a microscope) forms. On each page, rhyming text accompanies the line art to provide further educational information about each algal group. To aid in the coloring process, we also created a reference that provides actual photos from both the field and microscope. This work was hand-drawn in digital art applications and written by both Jordan Zabrecky and Taryn Elliott who both collected algal samples on the Salmon River in the summer of 2023 supported by Nation Science Foundation Division of Biology Grant Award #2042915.
