Questions

Subject: Writing

Question:

When writing for journals or any publication one must always identify the audience of interest. If the title of the magazine article was "Finding True Love in the Tinder Age" what might the audience of interest be?

Answer:

This title indicates that the readers would be interested in finding love, as well as acquainted with the Tinder app, so the writer is likely aiming for a young, "hip" audience that would better identify with the subject of the article.

Subject: Environmental Science

Question:

Please explain the basic principle of trophic cascades and the environmental significance of apex predators using the classic Yellowstone examples of wolves as apex predators and their cascading effects on other trophic levels in the system.

Answer:

In a density-independent environmental system, the apex predator regulates lower trophic levels by reducing numbers of primary consumers and thus increasing numbers of primary producers. In the example of the Yellowstone system, wolves are apex predators that prey on herbivores such as elk. Elk favor the woody vegetation of riparian environments and can cause serious damage when their populations remain unregulated, but the presence of wolves scares elk away from riparian zones and controls population sizes. Thus, the absence of wolves from the system may lead to the degradation of riparian zones over time.
