ClimateClimate
• Winter ranges from -65 to 30 degrees F
• Summer ranges from 30-70 degrees F
• winter is longer and is colder due to the low angle of sunlight.
– Causes weaker light

PrecipitationPrecipitation
• Gets roughly 40 inches of rainfall each year
• The further north in the Taiga the less precipitation
• 10-20 inches in the summer– Three month growing season
• 20-30 inches in the winter– falls in the form of snow, so it is not useable
to plants

Coniferous TreesConiferous Trees
• Most dominant plants in Taiga, that is why it is also called the coniferous forest
• Due to the short growing season most conifers are evergreen (don’t shed their leaves) in order to be able to photosynthesize all year

LeavesLeaves
• Their leaves have a lower surface area in order to conserve water.
• Their cuticle (waxy covering made of lipids/fats) is thicker to also prevent water loss

ConifersConifers
• Myccorhizae– A fungus that grows on the roots to absorb
water for the tree and in return the conifer provides glucose for the fungus. This is an example of mutualism.

Fire!Fire!
• Is a necessary adaptation that assists in the reproduction of certain species of conifers.
• The heat has to burn the resin from their cones in order to open the scales to receive pollen

LynxLynx• Insulation
–thicker amounts of fur keep the cat warm during the harsh winters

Foxes/WolvesFoxes/Wolves• Have a thick coat to protect against the
elements
• Burrows into the snow to avoid the cold and the wind
• Larger pads then its more southern ancestors in order to run on the snowy terrain

HibernationHibernation
• Hibernation is the resting period for some species of animals. During this, their metabolism, temperature, and breathing rate slows.
• They hibernate because there isn’t enough food to sustain the population.
