Glossary: Throughout this site, glossary entries appear in bold brown. Links to the complete glossary appear at the top and bottom of each screen. The glossary was created specifically for EcoHealth, so some words or phrases (such as airport malaria or squalamine), may be too new or specialized to appear in a classroom or household dictionary. Such terms could be the basis of a lesson on how language evolves to reflect new discoveries and insights.
