Neotropical

Part of speech: adjective

Definitions

1. Relating to the biogeographical region that includes South and Central America, the Caribbean, and parts of southern North America, characterized by diverse flora and fauna
2. Pertaining to the ecosystems and species native to the Neotropics, a region noted for its rich biodiversity and tropical climates
3. Describing the ecological zone encompassing Central and South America along with certain adjacent islands, which is recognized for its extensive variety of plant and animal life

Etymology: The term emerged in the realm of biogeography during the late 19th and early 20th centuries, as scientists sought to classify the Earth's regions based on their distinct flora and fauna. It combines the prefix "neo-" meaning "new" with "tropical," referring to the Earth's tropical zones. The prefix "neo-" stems from the Greek "neos," which means "young" or "new," signaling a more recent or modern phase. This adjective describes the tropical regions of the Americas, including South and Central America, the Mexican lowlands, the Caribbean islands, and parts of southern Florida. It serves to distinguish these areas from the "Palaeotropical" regions, which encompass the tropical zones of Africa, Asia, and Oceania. By using "neo-" to indicate "new," the term implicitly contrasts these New World tropics with the Old World tropics, reflecting the biogeographical history of species dispersal and evolution. The concept of the Neotropical realm gained prominence as naturalists and ecologists noticed unique patterns of biodiversity and endemism in these American tropics, which differed markedly from those in Africa and Asia. The word thus encapsulates not only geography but also evolutionary narratives about how life in the Americas developed differently from other tropical regions. While the word entered scientific English through Latinized Greek roots, its coinage reflects a modern attempt in the 19th century to impose order on the natural world by categorizing it into realms. This approach remains influential in disciplines like ecology, zoology, and conservation biology, where the distinctions between "neo-" and "palaeo-" tropical zones help clarify the distribution and history of tropical species.
