Cool Clues on the Tundra
Transcript of Cool Clues on the Tundra
Scientist Dr. Gus Shaver has discovered that climate change is effecting the world and may affect the tundra. Dr. Shaver wanted to experiment with the change on the tundra.
Questions and hypothesizes
Dr. Shaver placed green houses over tundra plants to reflect global warming.
Birch trees were one of the only plants that grew better with climate change.
Sedges, Wildflowers and other plants grew poorly or died with the new climate.
Some plants did better with climate change then others.
Some animals would be affected by climate change.
If global warming were to happen in the tundra then its ecosystem would be positively and negatively effected
Studying climate change on the tundra
Results and conclusions
Dr. Shaver realized global warming was occurring around the world and would probably happen on the tundra.
Students from Fran Bosi's college class in Queens, New York.
Dr. Shavers Questions and hypothesis:
What would global warming do to the tundra?
Would the Caribou change their diet or die off if their food source disappeared?
If the temperature grew warmer, then the tundra and its ecosystem would be thrown off.
On the tundra, the average temperature is 10 to 20 F degrees Fahrenheit.
Tundra covers 20% of the earths surface.
Animals that usually don't live in the tundra are moving to it because of global warming.
A rare animal named the pika is common in this biome and the only other place this animal can be found is in the grass land. It is still rare to the grassland.
The average precipitation is usually less then 15 inches a year
