- The temperate grasslands are situated around the outside of the tropics of Cancer and Capricorn >25 degrees north and south of the equator, in the middle of continents (yellow), therefor mostly in the ferrel cell/front
- The coniferous forests are situated from 50-60 degrees north of the equator (dark brown) therefor mostly in the polar cell/front
The dark green points are the main carniferous forests, the yellow points are the temperate grasslands
Coniferous Forest- Russia
Also known as Taiga or Boreal forest
The Taiga in relation to the Whittakers model
Climate:
- up to six month long winters
- strong winds
- subarctic and cold continental climate
- extreme temperatures
- low evaporation to precipitation- at 40-45cm per year, but still fairly dry because of the cold
- temp can change from warm to below freezing in a day
- mountainous terrain, with lakes and rivers
- they are made of mostly spodosoil because of the acid in the pines, because of cold there i slow decomposition
- also know as the alps
- large pine and evergreen forests
- in areas of patchy permafrost
- usually at an altutude of 3km or more
- isnt much plant biodiversity because of low CO2 levels
- quite a bit of animal diversity
- the largest human threat to the Taiga is deforestation because of the good food in the forests, and climate change increasing temperatures
- most plants are small perennial groundcover They protect themselves from the cold and wind by hugging the ground and they grow slowly
- or needle leaf, coniferous, or evergeen trees
- In Russia the Scott's pine is most dominant
- mostly warm blooded animals besides salamanders and frogs and some insects
- animals have layers of fat, hibernate or migrate in the cold
- short legs and ears to reduce heat loss
- large lungs and blood cells from pressure
- mostly fur bearing predators eg- the lynx, members of the weasel family, squirrels lemmings and vowls
- elk, moose, beavers, wolves and bears
- more then 300 species of birds, insect and seed eating like finches, crossbills and sparrows or omnivores and large raptors like eagles and raven
- many fresh water fish that can survive the cold
- predatory animals must be able to travel long distances to find food

Temperate grasslands in whittakers model
climate:
- evaporation to precipiation E=P or precipitation is a small bit larger, with 60 to 150cm per year
- temperate range is high, clear skies, low precipitation, drought
- average temperature in the Pampas 18c, warm and always windy (can get down to -40c in other countrie's grasslands)
- only has a wet and dry season
- in relation to whittaker's model the Pampas temperature average of 18c and precipitation 50cm a year
Temperate Grasslands- South America
The pampas
- Rolling terrains, mostly flat but may consist of small hills and mountains
- composed of rich mixes of grass and forbs
- extremely fertile soils
- many have been converted to agricultural lands for cereals wheat and grain, also used for cattle and sheep grazing
- human development- over grazing and overcropping led to erosion and desert formation
Two types- tall grass in more humid areas, and short grass with dryer air, colder winters and hotter summers

Flora
- grass browsing or burrowing animals
- underground owls, seed eating birds, finch, the greater rhea
- Geoffroy's cat, maned wolf, lama, bison, pronghorn, gophers, ground squirrels and the prarie dog, coyote, badger, ferret
- depends on specific place animal biodiversity
- lots of the animals live in herds for protection because of easy spotting from their prey
- perennial grasses adapted to drought, fire and cold, narrow straight stems for cooling, and strong roots to absorb nutrients
- flowers- eg sunflowers, water lillies, cat tails
- peas, herbs, reeds
