Summary Introduction
Introduction:
Edward O.Wilson and Robert MacArthur proposed ‘The Equilibrium Model of Island Biogeography’ in 1960. It is a comprehensive model that explains uneven distribution on the new island.
According to Edward O.Wilson and Robert MacArthur, the number of species on an island reflects the balance between the rates of immigration and extinction. The model predicts that island size is directly proportional to the number of species that the number of species increases with an increase in island size. The number of species decreases with a decrease in the distance from the source pool.

Students have asked these similar questions
what does it mean if the growth rate is 0.090, probability of extinction is 0.00, mean population is 240, and genetic diversity is 92? Please explain how they relate with each other.
You arrive on an alien planet and settle down to live there for a long time. There are very few species. Two of the species (A and B) are sometimes common and sometimes rare. When you start keeping track of population changes you discover that the population sizes fluctuate on a regular cycle in close synchrony. Species B always increases first, followed by species A.
Which of the following would be the best explanation for what you are seeing?
Group of answer choices
-Species A is a predator and there is a time lag between changes in the density of its prey and species A's population change
-Species A is a predator and it can respond instantly to changes in its prey population
-Species B is a predator and there is a time lag between changes in the density of its prey and species B's population change
-Species B is a predator and it can respond instantly to changes in its prey population
Plot survivorship curves for all three species illustrated in Table 1 on a single graph. Label the axes and provide a clear legend
convert it and make use of legend, so for the first species it would be 6months=1unit, then for the second species 1yr=1unit, and the third species would be 50yrs=1unit

Group of answer choices Extinction and extirpation are the same thing. Extirpation is the loss of a single population, while extinction is the loss of an entire species. Extinction only happens during a mass extinction.

Indicate whether these are type I, II, or III. b) Draw a graph of the equilibrium model of island biogeography, with number of species on the x-axis and rate of immigration and extinction on the y-axis. Label all your lines and indicate both the number of species present at equilibrium and the turnover rate at equilibrium.arrow_forwardA predators can feed on several prey species, but prefer to attack those with the weakest defenses. The same predator may shift to a different prey species that becomes more common or more easily overcome when the previousiy preferred prey had acquired better defenses against the predator. This shifting strategy, known as _____________, results in sequential or alternating bouts of pairwise coevolution between many different species. A. resource shifting B. coevolutionary alternation C. ecological character displacement D. cospeciationarrow_forwardThe example of the Heath Hen provides which of the following important lesson for managing small populations - Genetic drift is more powerful in small populations and can lead a species to extinction - Understanding the factors that make a population small are more important than the factors that ultimately drive it to extinction - Intensive management is successful for bringing back species from the brink of extinction - Allee effects can make managing a small population very difficultarrow_forward
