Taiga Climate
Climate Description:
Most of the Taiga climate is cold air from the Arctic Circle. The taiga is turned away from the sun in the winter, because of Earth’s tilt. Less of the sun's radiation reaches the ground to warm it up. Winter, lasts for six, to seven months. Summer is a rainy, hot and short season in the taiga. Fall is the shortest season for taiga. Spring brings flowers, the frozen ponds melt, and the animals come out from hibernation.
The lowest and highest temperatures that occur for taiga are the following:
Winter's LOWEST temperature in taiga is -65°F.Winter's HIGHEST temperature is 30° F.Summer's LOWEST temperature is 30° F.Summer's HIGHEST temperature is 70° F.
For half of the year, the average temperature is below freezing. In the winter the average air temperature is warmer than it is for tundra, which is north of the taiga. The taiga climate has an average annual rainfall of 12 - 33 inches (30 - 84 cm). Most of it falls in the summer as rain.

Plant adaptations:
Balsam Fir- An evergreen, which uses a variety of adaptations, including their shape, root structure, color, and leaf type. A major adaptation it has is losing its leaves during the winter months. Growing new leaves takes a lot of energy from the tree, and because the taiga's soil is nutrient-poor, and sun remains low in the sky, the energy needed to reproduce leaves is not available. http://maswan96.wix.com/boreal-forest-taiga#!adaptations

Black Spruce:Has waxy needles and thick bark to protect it from natural interference. It is also able to survive in the colder climates because of its layered twigs. This protects it from predators also. Its lack of a specific root system allows it to survive in nutrient-poor soil.
Jack Pine:Has developed waxy needles and thick rough bark. It is often used as lumber for houses, because of its naturally fire-resistant nature. When it is destroyed by fire, the seeds fall and germinates immediately or stays dormant until conditions are ideal. Once thought to be poisonous to the soil, many plant species actually grow with the Jack Pine.http://welcometo-thetaiga.weebly.com/plant-life-adaptations.html

Douglas-Fir: Can grow to heights in excess of 30m. Each forest contains only one type of tree and has little vegetation on the forest floor because it is dark and the soil is acidic.Trees are evergreen so they can photosynthesis when temperatures rise above 3°C.Leaves are needle shaped and therefore have a small surface area and are waxy. This reduces moisture lost by transpiration, important as these areas receive little moisture (less than 500mm)
The conical shape of the trees gives them stability in high winds. Bendy trunks also guard against high winds. Branches slope downwards so they do not snap under the weight of snow. Seeds are protected against cold in cones.Trees have wide spreading roots in shallow soils. Soils are shallow because of slow rates of decay.
Eastern Red Cedar: Have developed adaptations to deal with water limitations, varying climates and different soils. One adaptation that this tree does not possess is fire adaptation. Since Eastern red cedars don’t have buds at the base of the shoot, it cannot re-sprout when its top is damaged. Its wide distribution indicates adaptability to varying conditions.http://www.ehow.com/info_12154873_red-cedar-tree-adaptations.html#ixzz2l0aYLamH

Animal Adaptations:
Black Bear- Bears started to hibernate in the winter time to adapt to the winter climate

During the summer the bears will store their food as body fat for the winter. This fat gives enough nutrition for their hibernating bodies all winter long.

The bears conserve energy throughout the winter by hybernating

Bald Eagle: the adaptation that bald eagles take are changing color of feathers in order to confuse predators. The ermine, a small mammal, is a good example of this adaptation. The ermine changes to white in the winter to match the snow color and blend in. http://www.cotf.edu/ete/modules/msese/earthsysflr/taigaP.html

Bobcat:Two adaptations of the bobcat are sharp claws and teeth. The bobcat uses this for hunting and they will change fur color to blend in. The bobcat is common in North America, but it is rarely seen due to its camouflage. The bobcat's ears help it hear the quietest sound of its prey by swiveling front to back. They have tufts of fur on top of their ears and this improves their hearing.
Canadian Lynx:
The Canada lynx's wide paws work like snowshoes. The paws distribute the weight in order to attach to the snow really well.
Gray Wolf: The gray wolf has a lot of adaptations. Their coats are made of wooly fur to provide insulation and long hairs to keep out moisture. The gray wolf's large paws have fleshy pads and claws for traction these can spread to provide better support in snow.
Symbiotic relationships:
Mutualism: One example of mutualism in the taiga is moss growing trees. This protects the tree while also making a house for the moss. Another is the tachnid fly and the hemlock looper. The tachnid fly parasites the pupae of the hemlock looper which is another example of mutualism. One more is black spruce and lichen. Lichen gets food from the dead parts of the tree and gives the tree nutrients.
Parasitism: One example of parasitism is brain worms and caribou. The brain worm eats the brain of the caribou and the caribou dies. Another is that grape vines are turning into hosts for the parasite aphid and, as a result it dies because the aphid infected them.
Commensalism: One example of parasitism is brainworms and caribou. The brainworm eats the brain of the caribou, and the caribou dies. Another is that grape vines are turning into hosts for the parasite aphid and, as a result it dies because the aphid infected the. This is commensalism because the brain worm is benefited while the cariobou isn’t.
Predator: some examples of predator-prey relations are the lynx and the snow hare, and the falcon and the other birds that they eat.

Climate Description
-mostly coniferous forests consisting of pines, spruces and larches.
-The mean annual temperature generally varies from -5 °C to 5 °C, (23 °F to 41 °F)
-The winters, with average temperatures below freezing, last five to seven months.
-The summers are usually warm and humid. 18 °C (64 °F) is an average summer day.

Five Plant Adaptations
-Needles of pine trees are smooth to keep water in
-Spruce tree’s cone-like shape sheds ice easily
-Evergreen tree doesn’t lose leaves in the winter to save energy
-many trees have wax coating on leaves to prevent evaporation
-needles are dark to absorb more solar heat
Five Animal Adaptations
-Siberian tiger has long legs and large paws to help walk through deep snow
-porcupine has quills to keep predators away. Its quills will be stuck into the predator’s body
-ermine (small mammal) has a dark brown fur coat that turns white in the winter
-black bears go into heavy sleep (not hibernation) to stay out of the cold
-river otters have guard hairs to keep their fur from freezing
Symbiotic Relationships (Predation, Mutualism, Commensalism, Parasitism)
Predation: wolves and moose. The wolf eats the moose and the moose dies.
Mutualism: fungi and pine tree roots. Pine tree gets protection and fungi gets nutrients
Commensalism: Bald eagle and pine tree. Bald eagle gets nesting and the tree is unaffected
Parasitism: caribou and brain worm. The brain worm gets nutrients and the caribou loses control of its body and dies.
