1. On the savannah of African exist two animals, the African Wild Dogs (Lycaon pictus) and the Spotted Hyenas (Crocuta crocuta). Both of these animals occupy a very similar niche in their community – a social carnivore, which hunts in packs. However, when their niche does completely overlap the Hyena will win the fight. Use this information to answer the following questions. a) If these two animals were to occupy the same habitat, knowing what you know about these populations, what do you think the outcome of these two populations would be? b) The African Wild Dog hunts at twilight, while the Spotted Hyenas hunt at night. This separation of niches allows for what ecological process to happen? Why is it important that this process happens? c) The population of African Wild Dogs is much smaller, and very isolated from one another. If you were trying to prevent this animal from going extinct – what would you focus your resources on conservation wise? (There are a number of answers for…
1) Based on the food web, would you consider woolly mammoth a keystone species? Why or why not?
1. Two predators feed on small antelope. One predator weighs 100 kg, and the other weighs 35 kg. Explain what might happen if the two predators share the same area. 2. Wolves are reintroduced into a park. As a result, the vegetation changes. Explain how the changes to the vegetation happened. 3. Find out about the niche of wolves in their community. Determine if they are a keystone species. Then, write a one-page essay describing their role in their ecosystem.
1 “The Nature of Ecology” Biological scientists often study/research adaptations that have evolved within particular species. That is, they focus upon the biological aspects alone. Think critically about what ecology means and describe within a few paragraphs how ecologists approach the study of living organisms. As part of your answer, include a realistic and detailed example of a study by an ecologist.
