Series 1: Early Coursework and Research Papers, 1976-1983 Add to Shelf
Series 1 consists of Ripple’s papers written during his time in the master’s program at University of Idaho, as well as papers he wrote and exams that were taken while attending the Ph.D. program at Oregon State.

Box-Folder 1.02: Papers and Exams, 1981-1983 Add to Shelf
Series 2: Publications and Manuscripts, 1984-2013 Add to Shelf
Series 2 consists of Ripple’s publications, as well as drafts for many of these publications. The publications in this series are collaborative texts, as well as some written solely by Ripple. The majority of his publications are about his extensive work on trophic cascades, which are indirect interactions that can control entire ecosystems. This is seen when predators in a food web alter the behavior of their prey, which in turn lowers the predation on the next trophic level. These publications includes ERSAL's Remote Sensing Research journals and his extensive work on aspen regression, which looks at the impact of wolf extirpation on local ecologies. This series also includes a number of children’s books written by Ripple.
