Most remote oceanic islands have at least one unique species of flightless bird that shows little or no fear of humans or other large predators. Account for this observation.

Since different species of penguins may occupy the same habitat, explain why they may continue to remain separate species.

In one year, there were 18 males and 34 females. Over the following year, each female gave birth, of which 28 survived. Nine elephants died due to predators. A construction project cleared 50 acres of nearby forested land, causing 5 males and 19 females to immigrate into the experimental area. Competition for females increased, resulting in the emigration of 10 males to a new territory in search of mates.

Use the following simple predator-prey relationships to answer the questions about the system below (assume no other interactions exist in this system). Mice eat grain grown by a farmer before it can be harvested. The mice are consumed by several species of snakes, which themselves are consumed by hawks. A. If the population of snakes was suddenly wiped out by disease, explain the short-term effects on the grain, mice, and hawk populations, and why these effects would be observed. B. If the population of snakes were suddenly wiped out by disease, explain the long-term effects on the grain, mice, and hawk populations, and why these effects would be observed. C. Local farmers would like to use a biological, as opposed to a chemical, means to protect their crop. What would be the most effective way for farmers in this area to protect their grain crop naturally? Why? Edit View Insert Format Tools Table 12pt ✓ Paragraph BIUA V 2 ✓ T² v :

A 'live fast die young' life history strategy is associated with which type of environment? High resource availability High competition with others of the same species High stress / extreme conditions

What is the Predator Release Hypothesis? Explain how it works. What is ONE principle or idea that we studied in this course that can be illustrated using it (other than predation).  Explain how the predator release hypothesis fits into that idea.
