Chapter 22.2, Problem 2LO
Summary Introduction
To identify: The sympatric organisms formed from the two populations that are partially reproductively isolated.
Introduction: Reinforcement leads to character displacement after reproductive isolation mechanism. The two populations give rise to new hybrid known as sympatric

Describe two mechanisms that can decrease gene flowin sympatric populations, thereby making sympatricspeciation more likely to occur.
Differentiate between how prezygotic and postzygotic isolating mechanisms lead to reproductive isolation.
what are some plausible phenotypic changes that we might see in different vector species as climate change progresses? How might these changes affect interspecific competition?

Select all the correct options. Select 3 correct answer(s) Leaving released individuals aside and focusing on monitoring the population as a whole. Avoid advertising the success of program to local communities so that released individuals are not bothered by curious people. A long-term plan that involves monitoring the population over many years. Monitoring the costs of the program so that cost-effective analysis can be made. Monitoring other ecosystem elements beyond the released species, such as prey and vegetation.arrow_forwardIn 1956, two Corsican mouflon sheep were introduced to Haute Island, which has an area of 7.00 km². In 1957, the pair were able to reproduce for the first time. By 1977, the population had grown to 600 sheep due to abundant food sources and the lack of natural predators in the area. Since then, the Haute Island sheep population has fluctuated between 200 and 600 sheep. In 1990, 250 mouflon sheep were relocated from Haute Island to a neighboring island with similar terrain, soil, vegetation, and weather patterns. The neighboring island has an area of 10.0 km². 1. Compare the density of the Corsican mouflon sheep population on Haute Island in 1977 with the neighboring island in 1990. Record your answers to three significant digits. 2.a. Explain how the growth of the Corsican mouflon sheep population on Haute Island caused interspecific competition? b. What prevented the Haute Island sheep population from increasing beyond 600 sheep?" 3. What was the growth rate of the Corsican mouflon…arrow_forward
