Speculate as to why more females were introduced than males by 1973.
(in an attepmt to increase the local food supply for people,humans introduced 26 reindeer (24 females and 2 males) to island off the coast in alaska in 1910)
the reindeer population has soared to 2000 what evidence suports the hypothesis that the carrying capacity for reindeer has been exceeded.
3. the introduction of a new speices can cause major changes in an ecosystem. should the reindeer have been put on the isalnd? expalin your posistion
.please naswer the three question using this paragraph
In considering part 2 of your question, it would seem that a population increase of almost 2000 animals (from 26 in 1910 to 2000 in 1973) certainly has the danger of exceeding the "carrying capacity for reindeer." On the other hand, I don't see any information about the size of the island or how the reindeer are doing, so it's hard to answer the question with any certainty. The same holds true with question 3. It would certainly seem that an increase of almost 2000 large animals could create havoc (especially with a small land size), but again it's hard to say without knowing more information. How are other species on the island doing?
The reason for introducing more females than males is quite clear -- when you have more females, you have more potential for having babies and multiplying the herd. Two males can presumably keep 24 females pregnant as often as the females are able to be. So there would be no point in sending more males.
If you want evidence that carrying capacity has been exceeded, you need to look at the reindeer themselves. Are they dying of hunger? Are they failing to reproduce? And you have to look at the rest of the ecosystem. Are the plants that reindeer eat being overgrazed?
