Analyzing interspecific competition

A hypothetical bat species (species 1) lives in a city. Another hypothetical bat species (species 2) established a population in the same city after a number of individuals escaped from a zoo. In isolation, each species prefers to roost in buildings that are three or more stories tall.

After species 2 became established in the city, species 1 began roosting only in buildings less than three stories tall, whereas species 2 roosted in buildings three or more stories tall. Observers determined that the bright streetlights at ground level had previously deterred most bats from roosting in shorter buildings. Over many generations of existing in the same city with species 2, species 1 showed changes in eye size and retina structure.

Complete the following statements about the two bat species.

Explain when competition will occur within a species (intraspecific) and between two different species (interspecific). Explain Gause’s competitive exclusion principle (CEP). What was his reasoning for concluding that two species occupying exactly the same niche could not coexist indefinitely ? Species interactions like competition and predation can prevent a species from occupying its fundamental niche. Explain the concept of the realized niche. How does the realized niche of a species compare to its fundamental niche?

What is character displacement, and why does it support the idea that competition affects the reproductive potential of individuals in competing species? Explain the evidence for character displacement in two species of Galapagos finches . Explain how the components of natural selection acting within populations of these two species could result in the apparent character displacement of beak depth observed when they occur together on the same island. To do this assume that when the two species first came together on the same island they exhibited the same overlapping distributions of beak sizes as are now observed on the islands where only one of the species is found. Now ask the question, "Which individuals within the G. fulginosa population had an advantage over other individuals of the same species when the competing species G. fortis was present"? Recall that for G. fulginosa, G. fortis represents an environmental factor. Then use the components of NS to explain how this would result in a decrease in mean beak size in the G. fulginosa population over time. Use the same reasoning to explain the increase in mean beak size in G. fortis.

Explain Connell’s experiments on competition between Balanus and Chthalmus barnacles . Explain the results of removing each species on the distribution of the other and what this indicated about what factor was limiting the distribution of each species. Explain how specialization and resource partitioning allow insectivorous warbler species to coexist

One of the best known of Darwin's sets of observations from his voyage on the Beagle involved a group of birds often called "Darwin's Finches," which were collected from the Galapagos Islands. These birds give us a classic example of a phenomenon called adaptive radiation. Explain what this phenomenon is. Why would this have occurred on the Galapagos Islands, not just to the finches, but to most of the other species found on the island? Be specific--this question is about the Galapagos islands specifically. This explanation should involve concepts like fundamental and realized niches and resource partitioning.
