16. What is a Field Guide? • Takes knowledge about taxonomy & diversity of organisms (or other entities) and converts it into a simple, portable, representation. • Covers ranges, niches, phenotypes, genetics, means of identification, etc. • Can include a checklist. • Used by amateurs & professionals.
