Ecology - Community Dynamics Questions

1. The extensive size of the fires that burned Yellowstone National Park in 1988 caught both land managers and ecologists by surprise. Many forests suffered intense infernos that removed virtually all vegetation. Some speculated that the park would never recover. Based on what you learned in this section, is it likely that the park was irrevocably altered? Provide evidence for your position.

2. Wolves, like their domestic counterparts, are susceptible to canine parvovirus, a disease that can cause severe diarrhea, dehydration and death. Although populations typically rebound from outbreaks of the disease, what would you expect to happen to the aspen if a deadly strain of parvovirus decimated the wolf population? Why?

3. Redwood trees (Sequoia sempervirens) have more biomass than any other plant species in western redwood forests. They greatly impact the other plant and animal species that live in redwood forests. If removed, most understory plants and their associated herbivores could not survive. Are redwood trees keystone species? Why or why not?

Explanation / Answer

Yes, is it likely that the park was irrevocably altered. The biological makeup of plantation and species growing and residing in the park has drastically changed. vegetation at one point was completely removed and the park was grown with new vegetation. Moreover, lake was poisoned to protect native trout which also caused an irrevocable change in species biological makeup.
