Transcript of Arctic Tundra
Herbivores, Omnivores, Carnivores and Decomposers
~Stores nutrients so new leaves can be made quickly next spring. (More leaves, more photosynthesize.)
~Bottom of tundra lake beds & in & around bogs & fens.
~Adapts well in cold climates.
Arctic Moss (Calliergon giganteum)
~Important food source for certian animals.
~Berries can be eaten.
~Non-nutrient soils (Sand, rock out crops, & shall soils.)
~Can make food when the temperature gets very low & there is little light.
~ Northern Region
~ Ground and rocks
~Provide nutrients (Vitamin C/A and Calcium.)
~ Other wet areas
~Leaves produce Vitamin C
~ Forest areas
~Doesn't have a specific niche exactly, because it has different relationships with its own species and other animals.
~Can survive where others can't
~ Eat a lot of the vegetation.
~ Live anywhere where there is food and water.
~Live in herds.
~In other seasons they eat buds, berries, leaves, roots, and bark.
~Forage Shelter In snow areas
~Eat birch and willow buds and catkins when available. It will also eat various seeds, leaves, flowers and berries of other plant species
~Rocky sloped areas (Females prefer areas w/ brush.)
~Eat Berries, honey and Salmon
(Same as Grizzly Bears)
~Eats other consumers and producers
~A lot of forest area and snow
~Scavengers (Finds food to eat)
~ Provides food for cubs
~ Mountains (Snow)
~Breaks down dead organisms into simpler substances and nutrients to be absorbed by the plants for survival.
Bacteria & Fungi
Through out all 12 months it is cold. Summer has a brief period of milder climates when the sun shines 24 hours a day. But even the sun can't warm much.
The main Latitude of the Tundra is 75 degrees North to 60 degrees
The Tundra is pretty much made up of:
~Mountains of snow
~The relationship is seen between the reindeer and ptarmigan, wherein the latter is the beneficiary
A relationship between a Caribou & it's microorganisms in it's gut.
~ Caribou provides food for microorganisms-microorganisms help animal digest.
The alga being photosynthetic , uses carbon dioxide and light to produce sugars to feed itself as well as the fungus. And the fungus retains water for both of them and also helps the algae to obtain minerals from substrate. (which is usually a rock.)
Includes tick and mite infestation in mammalian species. In such infestations, parasites stick to the skin of host organisms and suck their blood.
Parasites affects various mammalian species including reindeer, Arctic foxes, musk oxen, Arctic wolves, etc.
~Such as Tapeworms which develop in the mammals stomach.(Eat off the food it eats.)
Human Impact and Ecosystems
~Oil spills (Killing Wildlife and damaging to the tundra.)
~Buildings and roads put heat and pressure on the permafrost, causing it to melt.
~Push aside native vegetation and reduce diversity of plant cover.
