Research on the tundra
We looked up Planet Zork’s tundra habitat and we realised there were 2 kinds of tundras: the arctic tundra and alpine tundra. From what we know of Planet Zork, its habitat is an arctic tundra as it is not specifically on a high mountain.
Conditions of a tundra:
- extremely low temperatures
- little precipitation (<– geography)
- simple vegetation with no deep root systems
- limited drainage
- short summers of 50-60 days
- permanent layer of frozen soil (permafrost)
- top layer of soil turns waterlogged in summer
- slowly decaying layer of dead matter
Animals in the tundra are
- adapted to handle long, cold winters
- breed and raise young quickly in the summer
- Mammals and birds have additional insulation from fat
- Many hibernate during the winter because of scarcity of food.
- Or: Migrate south in the winter, like birds do.
- short and group together to withstand strong winds, cold temperatures
- photosynthesize in low light conditions
- most reproduce asexually and quickly within the short summers
- roots run horizontally rather than vertically into the soil (due to permafrost)
This gave us a better idea of the conditions our organisms had to face. After a brief discussion, we decided that our microhabitat would be on a plain as its conditions are not as harsh as those on the mountains.
–> But our organisms would not have shelter in this way 😦
So, we decided to include a mountain with caves as their shelter. This list summarises the habitat layout and the abiotic factors in it.
- Plain (grassland)
- Covered with short plants that are clustered together
- A mountain with caves is located at the far end of the grassland
Influential abiotic factors
- Temperature – Low
- Winter – extremely low temp., long
- Summer – warmer temp., short
- Wind – strong
- Soil – permafrost present in winter, waterlogged in summer
- Water – little rainfall
- Light – little sunlight
