Nearctic ecozone

Target entity: Nearctic ecozone
Context triple: [Chihuahuan Desert, partOf, Nearctic ecozone]

• A. Arctic-subarctic transition zone
  The Arctic-subarctic transition zone is an oceanographic and ecological boundary region where cold Arctic waters and ecosystems gradually shift into the relatively warmer and more temperate subarctic environment.
• B. Palearctic realm
  The Palearctic realm is a major biogeographic region encompassing Europe, North Africa, and most of temperate and northern Asia, characterized by its diverse climates and ecosystems.
• C. Arctic region
  The Arctic region is the Earth's northernmost polar area, characterized by extreme cold, sea ice, tundra landscapes, and unique ecosystems adapted to long periods of darkness and light.
• D. Northern Lakes and Forests ecoregion
  The Northern Lakes and Forests ecoregion is a heavily forested, lake-rich landscape of the upper Great Lakes region characterized by mixed conifer–hardwood forests, abundant wetlands, and a cool northern climate that supports diverse wildlife.
• E. Great Lakes–St. Lawrence forest region
  The Great Lakes–St. Lawrence forest region is a mixed-wood ecological zone in eastern Canada characterized by a transition between boreal coniferous forests and southern hardwood forests, supporting high biodiversity and numerous protected areas.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
