Marion B. and Tesha K.

(“Marietta”)

location
LOCATION

-South of the Arctic tundra

-Latitude: around 60°

-In northern regions across North America, Asia, and Europe

(“Wikipedia”)

climate
CLIMATE
  • Sub arctic
  • Long Winters
  • Dry and cold
  • Short summers

(mild-warm)

19 hrs. sun

  • Winter: 6-8 hrs. sun

(“Marietta”)

statistics
STATISTICS
  • Avg. annual temp: 0°C (≥-5°C ≤5°C)
  • Avg. annual precipitation: 100-125cm.
  • Temperature Range: 41°C

(“Blue Planet Biomes”)

flora types
FLORA TYPES
  • Trees: conifers (evergreens, firs, etc); needles all year long

-produce cones instead of flowers (“Coniferous Forest”)

--able to endure intense cold and drought during winter (Living in the Environment)s

-some mosses and algae grow on ground

-needles reduce surface area loose less water

-needle coating=waxy and waterproof

-stomata sunken in wind protection

-dark color absorbs heat photosynthesis sooner

-winterfrozen soil, harsh climatelow plant diversity

(“Marietta”)

fauna
FAUNA

(“Marietta”)

  • Predators (with fur): weasel family, lynx, some tigers

-feed on rabbits, squirrels, lemmings, and voles

-elk, moose, beavers=large herbivores

  • Birds: insect-eaters (wood warblers), seed eaters(finches, sparrows), omnivores (ravens) and some migratory birds
