Transcript of Arctic Tundra

By:Mariana Chavez
Arctic Tundra
Consumers:
Herbivores, Omnivores, Carnivores and Decomposers
Abiotic Factors
Symbiotic Relationships
Biotic Factors
(Living Organisms)
Producers
Niche:
~Stores nutrients so new leaves can be made quickly next spring. (More leaves, more photosynthesize.)
Habitat:
~Bottom of tundra lake beds & in & around bogs & fens.
~Adapts well in cold climates.


Arctic Moss (Calliergon giganteum)
Niche:
~Important food source for certian animals.
Habitat:
~Dry
~ Cold
~Open places
Arctic Willow
(Salix arctica)
Niche:
~Berries can be eaten.

Habitat:
~Dry
~Non-nutrient soils (Sand, rock out crops, & shall soils.)
Bearberry

Niche:
~Can make food when the temperature gets very low & there is little light.
Habitat:
~ Northern Region
~ Ground and rocks
Caribou Moss
(Lichens)
Niche:

~Provide nutrients (Vitamin C/A and Calcium.)
Habitat:
~Near Creeks
~Mashes
~ Other wet areas
Diamond-Leaf Willow
Niche:
~Leaves produce Vitamin C
Habitat:
~Wet Meadows
~Bogs
~ Forest areas
Labrador Tea
Niche:

~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
Habitat:
~Mountains
~Forests
~Fields
Caribou
Niche:
~ Eat a lot of the vegetation.
Habitat:
~ Live anywhere where there is food and water.
~Live in herds.
Musk Ox
Niche:
~In other seasons they eat buds, berries, leaves, roots, and bark.
Habitat:
~Forage Shelter In snow areas
Arctic Hare
Niche:
~Eat birch and willow buds and catkins when available. It will also eat various seeds, leaves, flowers and berries of other plant species
Habitat:
~Elevated
~Rocky sloped areas (Females prefer areas w/ brush.)
Rocky Ptarmigan
Niche:
~Eat Berries, honey and Salmon
Habitat:
~Mountains
~Meadows
~Valleys
Grizzly Bears
Niche/Habitat:
(Same as Grizzly Bears)
Brown Bears
Niche:
~Eats other consumers and producers
Habitat:
~A lot of forest area and snow
Arctic Wolves
Niche:
~Scavengers (Finds food to eat)
Habitat:
~Hillsides
~River banks

Arctic Fox
Niche:
~Hunts
~ Provides food for cubs
Habitat:
~Cold
~ Snow
~ Mountains (Snow)
Polar Bear
Niche:
~Breaks down dead organisms into simpler substances and nutrients to be absorbed by the plants for survival.
Habitat:
EVERYWHERE!!!!!
Bacteria & Fungi
Description:

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.
Climate
Precipitation
&
Temperature
The main Latitude of the Tundra is 75 degrees North to 60 degrees
Latitude
The Tundra is pretty much made up of:
~Plains
~Hills
~Mountains of snow
~No trees
~Water.
Topography
(Non-living)
Example:
~The relationship is seen between the reindeer and ptarmigan, wherein the latter is the beneficiary
Commensalism
Example One:
A relationship between a Caribou & it's microorganisms in it's gut.
~ Caribou provides food for microorganisms-microorganisms help animal digest.
Example Two:
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.)

Mutualism
Example One:
Includes tick and mite infestation in mammalian species. In such infestations, parasites stick to the skin of host organisms and suck their blood.
Example Two:
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.)
Parasitism
Human Impact and Ecosystems
(H.I.P.P.O)

Habitat Destruction
~Oil spills (Killing Wildlife and damaging to the tundra.)
~Buildings and roads put heat and pressure on the permafrost, causing it to melt.

Invasive Species
~Push aside native vegetation and reduce diversity of plant cover.
Population
Over-exploitation
Pollution
