he tundra, where both reindeer and wolves live, the number of reindcer in a herd does not exceed the rrying capacity of the environment. In 1944, the United States Coast Guard transported 29 reindcer to St Matthew Island in the Bering Strait. St. Matthew Island has the typical climate for a tundra, but no wolres live there. The graph shown in Figure 2 represents the growth curve for the reindeer population there. Figure 2 6000 6000 5000- 3000 2000 1000- 29 reindeer 000introduoed 42 reindeer let 1945 1950 1955 1960 1965 laindeor population's growth on St. Matthow Island 1. What is the increase in the reindeer population increase between 1945 and 1963 12 What is the decrease in the reindeer population decrease between 1963 and 1966 13. Did the reindeer exceed the carrying capacity of their environment? Explain your answer. 14. Why do you think the population increased so rapidly in less than 20 years? 15. Why do you think that the population declined so rapidly, from 6000 to 42, in 3 years? 16. What do you think would have happened if wolves had been brought to the island with the reindeer?Explanation / Answer
11. In 1945, the U.S Coast guard establishes a LORAN ( LONG RANGE RADIO NAVIGATION SYSTEM) on St. Mathews islandwith a crew of 19 mens. 29 reindeers were indroduced in the island as backup food source. The men ledt the island and reindeers were ledt behind. reindeers found themselves on the island rich in their favourite food, 'LICHENS'. with abundant of food and no natural predator harming them,reindeers feed on them in large quantities and breed prolifically resulting in the increased population.
12. With abundant of food and no natural predator harming them,reindeers feed on them in large quantities and breed prolifically. The reindeer are in exceelent health fat from their nutritious diet lichen.Their huge apetite has eliminated all the islands lichen lefting their feeding on grass. With increased competion on food, the animals body weight has dropped with the remainings of skeleton with only 41 females amd 1 fertile male left .
