1 World Biomes

2 Rainforest Climate Region: Tropical Wet  Very hot and wet  Hydrologic cycle repeats often here  Rains more than 90 days a year Earth's most complex land biome http://www.cotf.edu/ete/modules/msese/earthsysfl

3 Bougainvillea Plant Adaptations  Sunlight is a major limiting factor  Little sun reaches the floor  Plants grow in layers (canopy receives most light) Bangul Bamboo

4 Wagler’s pit viper Silvery Gibbon Slender Loris http://www.blueplanetbiomes.org/rnfrst_animal_page.htm Animal Adaptations  Live in different levels of canopy  Many animals are specialists and require special habitat components to survive  Camouflage is common

5 Climate Region: Humid Continental 4 distinct seasons: spring, summer, autumn, winter mild summers and winters Almost all are located by an ocean Much of the human population lives in this biome http://www.runet.edu/~swoodwar/CLASSES/GEOG235/biomes/tbdf/tbdf.html Temperate Deciduous Forests

6 White Birch Lady Fern Geulder Rose Plant Adaptations Birchhttp://www.blueplanetbiomes.org/deciduous_plant_page.htm  Deciduous forests grow in layers  More sunlight reaches the ground compared to a rainforest so you will find more ground dwelling plants.  More diversity in the deciduous forest vs. the coniferous forest due to increased sunlight.  Trees adapt to varied climate by becoming dormant in winter

7  Adapt to many seasons  Lose Winter Coat  Eat from different layers of the forest Bald Eagle Fat Dormouse Least Weasel http://www.blueplanetbiomes.org/deciduous_animal_page.htm Animal Adaptations

8 Taiga aka Northern Coniferous Forest or Boreal Forest Climate Region: Subarctic  dominated by cold, arctic air  half the year, the temperature is below freezing  only found in the northern hemisphere

9 Balsam Fir  Low sunlight and poor soil keeps plants from growing on forest floor  Coniferous (needle-bearing) trees are abundant  Needles long, thin and waxy Fireweed Plant Adaptations http://www.inchinapinch.com/hab_pgs/terres/coniferous/plants.htm

10 Moose  Adapt for cold winters  Burrow, hibernate, warm coat, insulation, etc. Great Grey Owl Animal Adaptations http://www.inchinapinch.com/hab_pgs/terres/coniferous/animals.htm

11 Savannas (Tropical Grasslands) Contain the greatest number of grazing animals on Earth. Climate Region: Tropical Wet/Dry  Temperature doesn’t change much; 68 ◦ -86 ◦  Dry winters and wet summers http://www.cotf.edu/ete/modules/msese/earthsysflr/savannah.html

12 Whistling Thorn Umbrella Thorn Acacia Plant Adaptations  Grow in Tufts  Resistant to Drought  Many plants have thorns and sharp leaves to protect against predation. http://www.blueplanetbiomes.org/savanna_plant_page.htm Kangaroos Paws Baobab

13 Adapt for short rainy season—migrate as necessary Limited food leads to vertical feeding Reproduce during rainy season—ensures more young survive Zebras Chacma Baboon Animal Adaptations  http://www.blueplanetbiomes.org/savanna_animal_page.htm

14 Steppe http://www.blueplanetbiomes.org/steppe.htm Climate Region: Semiarid  Less than 50 in/year precipitation  Very harsh place to live  Found in the middle of continents and in the lee of mountains

15  most abundant are plants called Bunch grasses, fine bladed grasses that grow in clumps to preserve water Tumbleweed Sweet Vernal Plant Adaptations http://www.blueplanetbiomes.org/steppe_plant_page.htm

16  Many migrate, hibernate or burrow during extremes in temperature and precipitation http://www.blueplanetbiomes.org/steppe_animal_page.htm Animals Adaptations Mongolian Gerbil Saiga Antelope Gazelle herd

17 Grasslands Climate Region: Semiarid Many different types of grasslands; some tropical and some dry On every continent except Antarctica Very fertile soil http://www.blueplanetbiomes.org/steppe.htm

18 Sod-forming grasses that won’t dry out or blow away in wind. Fleabane Buffalo Grass Prairie Plant Adaptations http://www.blueplanetbiomes.org/prairie_plants_page.htm

19 Many adaptations to survive extremes Prairie dog Bobcat http://www.blueplanetbiomes.org/pampas_ animal_page.htm Prairie Animal Adaptations Geoffrey’s cat

20 Chaparral Climate Region: Mediterranean  Hot, dry summers, mild, wet winters  Slight variations in seasonal temperatures…NICE! California Chaparral Mediterranean Chaparral http://www.blueplanetbiomes.org/world_biomes.htm

21 Plant Adaptations  Mostly low-lying shrubs and small trees.  Many plants have leathery leaves to resist water loss  Many plant species have oils in leaves to help them resist fire…the fire will take out “weaker” plants that don’t belong. Blue Oak Fairy Duster

22 Animal Adaptations  Camouflage—to avoid predation  Many animals will change their diet as the season changes. Puma Aardwolf

23 Deserts The driest places on Earth! Climate Region: Arid  Less than 10 in/yr of rain  Little to no topsoil due to high winds.  Dry belt at 30º latitude http://www.cotf.edu/ete/modules/msese/earthsysflr/taiga.html

24 Joshua Tree Plant Adaptations:  Spines  Succulents  Thick, waxy cuticle  Shallow, broad roots Barrel Cactus Ocotollio  http://www.blueplanetbiomes.org/desert_plant_page.htm

25 Animal Adaptations:  Get water from food  Thick outer coat  Burrow during day  Large ears  Smaller animals = less surface area Javelina Bob Cat Armadillo Lizard http://www.blueplanetbiomes.org/desert_animal_page.htm

26 http://www.runet.edu/~swoodwar/CLASSES/GEOG235/biomes/tundra/tundra.html Tundra Climate Region: Tundra  Unusually cold and dry climate  6-10 inches of rain a year  Temperature ranges from -20◦F in winter to 50 ◦ F in summer  Permafrost layer One of the most fragile biomes on the planet

27 Plant Adaptations  Growing close to the ground  Having shallow roots to absorb the limited water resources.  Trees grow less than 1 m high! cottongrass Reindeer lichen Woody shrubs

28 Small ears Insulation, thick coat Many visitors = migration Little competition = Few predators Arctic fox snowy owl Grizzly Bear Animal Adaptations

29 Alpine Climate Region: Highland  Dangerous amount of UV rays  12 in of precipitation a year  Summer temperature ranges from 10 ◦ F and 50 ◦F  Night temperature almost always below freezing One of the coldest biomes on the planet

30 Plant Adaptations  No trees can grow  Vegetation includes tussock grasses, small-leafed shrubs, and heaths

31 Must adapt to cold weather Animals in the alpine biome include: mountain goats, sheep, elk, beetles, grasshoppers and butterflies. Animal Adaptations
