Objective 2: Meta-review of fish taxa
We conducted broad and succinct reviews of sticklebacks, PST, and
lampreys that focused on books, book chapters, review articles, and
other peer-reviewed literature to provide and describe the number of
species, their evolution, trait diversity, and use of terms to describe
ISD. We chose to do a meta-literature review because the exponential
increase in articles for these species (e.g., Wootton 2009) rendered
exhaustive reviews untenable for the scope of this paper.
