Monographs of the Western North American Naturalist publishes peer-reviewed original research pertaining to the biological natural history of western North America (i.e., United States west of the Mississippi River, Mexico, and western Canada). Typically, monograph articles are of a breadth and length that exceeds the specifications of the associated quarterly journal Western North American Naturalist.

Aims: Over the years the monograph series has firmly established itself as a forum for reporting original research on natural history topics and research methods, both descriptive and analytical. Our goal is not only to continue but to expand this publishing tradition.

Scope: Monographs of the Western North American Naturalist places neither restriction nor preference on manuscripts within the disciplines of the biological sciences.
