biogeographical region

Thân thiện

A biogeographical region is often marked by unique species of plants and animals.

Definition

1. Noun:
   • A biogeographical region is an area of the Earth's surface defined and classified primarily by its distinctive plant (flora) and animal (fauna) life. This classification considers the natural distribution patterns of species and ecosystems, often influenced by factors like climate, geography, and evolutionary history. It is a fundamental concept in biogeography for studying how life is organized across the planet.

Usage

• The term is used in scientific contexts such as ecology, biology, geography, and conservation to describe large-scale ecological divisions.
• It helps in comparing biodiversity, understanding species origins, and planning conservation strategies across continents.
• Example: "When studying lemurs, scientists focus on Madagascar because it is a unique biogeographical region."

Examples

• Noun:
  • The Amazon Basin is a biogeographical region characterized by its immense rainforest and unparalleled biodiversity.
  • Conservation efforts often target endemic species within a threatened biogeographical region.
  • Australia is often cited as a distinct biogeographical region due to its long isolation and unique fauna like marsupials.

Advanced Usage

• "To delineate a biogeographical region": To map or define the boundaries of such an area based on biological data.
  • Researchers used species distribution models to delineate the new biogeographical region.
• "Biogeographical regionalisation": The process or study of dividing the world into biogeographical regions.
  • The book presents a new global scheme for biogeographical regionalisation.

Variants and Related Words

• Biogeography (n): The scientific study of the geographic distribution of species and ecosystems.
  • She specializes in island biogeography.
• Biogeographic (adj): Relating to biogeography.
  • The biogeographic patterns of birds were analyzed.
• Ecoregion (n): An ecologically and geographically defined area, often smaller than a biogeographical region, with characteristic natural communities.
  • The freshwater ecoregion is a subset of the larger biogeographical region.

Synonyms

• Biogeographic province: A similar term for a major regional division of the Earth's biota.
• Floristic/faunistic region: Emphasizes the plant or animal components, respectively.
• Biome: A major ecological community type (e.g., desert, tundra). While related, a biome is defined more by its dominant vegetation and climate, whereas a biogeographical region is defined by the total distribution of flora and fauna and may contain multiple biomes.

Related Phrases

• Transition zone: An area where two biogeographical regions meet and species from both are present.
  • The savanna acts as a transition zone between the desert and forest biogeographical regions.
• Endemic to a region: A phrase describing species found only within a specific biogeographical region.
