These Three questions are also in relation to the graph. The next 3 questions refer to the followingThe study of population settlement on newly formed islands involves not only an assessment of thedistance from the islands to the mainland nearby, but also research into the factors involving themovement of species from the mainland to the islands. Immigration of organisms from mainlandpopulations establishes island populations, yet the extinction of species on these islands is possible asthey struggle to take hold. The plot below shows the immigration and extinction rate curves, à and u,for two recently formed volcanic islands, A and B, located near a large mainland source.2, immigration rate ofnew species per yearu, extinction rate ofspecies present per year5050Island AIslandsA and B4040303020 +20Island B10 +1050100150200Species present on island (S)57. Which of the following must not be true given the immigration curves for island A and island Babove?a. Island B is farther from the mainland than island A.b. Island B is the older of the two islands.c. Island A experiences a higher number of immigrants from the mainland.d. Both islands are the same size and elongate, but for island A the longest axis is orientedperpendicular to the mainland, whereas for island B the longest axis is oriented towardsthe mainland.c. Islands A and B are very dissimilar in their diversity and quality of habitats.58. An analysis of these curves reveals which of the following pieces of information?a. Some species colonizing these islands are better colonizers than others.b. The dispersal of these organisms is due to wind rather than to water currents.c. Island A is larger in size than island B.d. As species accumulate on the islands, their individual extinction probabilities increase.e. Islands A and B are very dissimilar in their diversity and quality of habitats.59. When island A reaches equilibrium, which of the following is correct?a. The rate of species turnover on island A is 10 species per year.b. The rate of species turnover on island A is 14 species per year.c. The rate of species turnover on island B is 10 species per year.d. The equilibrium number of species on island A is approximately 125 species.c. The equilibrium number of species on island A is approximately 200 species.

The given graph is of rate of immigration and extinction in two islands A and B. Using the graph,…

In 1956, two Corsican mouflon sheep were introduced to Haute Island, which has an area of 7.00 km^2. 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 sheep and 600 sheep. In 1990, 250 mouflon sheep were relocated from Haute Island to a neighbouring island with similar terrain, soil, vegetation and weather patterns. The neighbouring island has an area of 10.0 km^2. 1. Compare the density of the Corsican mouflon sheep population on Haute Island in 1977 with the neighboring island in 1990. (three sig digits) 2. Explain how the growth of the Corsican mouflon sheep population on Haute Island caused interspecific competition ? 3. What prevented the Haute Island sheep population from increasing beyond 600 sheep? 4. What was the growth rate of the Corsican mouflon sheep population on…
Which of the following is not a part of the red list criteria for "critically endangered" species? The population is expected to decline by 25% or more within 3 years or 1 generation. The species has a restricted range <100km2 at a single location and there is observed or predictive habitat loss, fragmentation, ecological imbalance or heavy commercial pollution. Extinction probably is greater than 50% within 10 years or 3 generations. The total population size is less than 200 mature individuals.

Trumpeter swans were once widespread and abundant in North America. However, a combination of heavy hunting pressure and habitat lost drastically 4 reduced the species’ population down to less than 70 individuals in the wild by the mid-1930s. By the mid-1980s, Trumpeter swans were more prevalent again in Alberta, especially near Grande Prairie. The following graph depicts the estimated number of Trumpeter swans in Alberta, carried out at five-year intervals from 1985 to 2010. What growth pattern of the Trumpeter swan population in Alberta is being observed? What environmental conditions allow the growth pattern that you identified? What may cause the growth pattern that is being observed to change?

The population is projected to decrease by 25% or more within a span of 3 years or 1 generation. 2. The species possesses a limited range of less than 100km2 in a solitary location, and there is evidence of or anticipated habitat loss, fragmentation, ecological imbalance, or significant commercial pollution. 3. The likelihood of extinction exceeds 50% within a timeframe of 10 years or 3 generations. 4. The overall population size consists of fewer than 200 mature individuals.
