Objective 4: Compare definitions with term use and make recommendations
We compared classical and authoritative definitions (Objective 1) with the meta-review (Objective 2), and trends in use of the terms ecotypes and life history (Objective 3). We addressed the questions: Are there clear patterns in how terms are used in particular contexts? Do redundancies or ambiguities exist in the use of some terms that suggest that some terms ought not to be used?
