The theory of island biogeography was experimentally tested by E.O. Wilson and his student Daniel Simberloff in the mangrove islands in the Florida Keys. Species richness on several small mangroves islands were surveyed. The islands were fumigated with methyl bromide to clear their arthropod communities. Following fumigation the immigration of species onto the islands was monitored. Within a year, the islands had been recolonised. Islands closer to the mainland recovered faster and larger islands had more species at equilibrium as predicted by the Theory of Island Biogeography. The theory proposes that the number of species found on an undisturbed island is determined by: immigration, emigration and extinction. Immigration and emigration are affected by the distance of an island from a source of colonists. Usually this source is the mainland, but it can also be other islands. Islands that are more isolated are less likely to receive immigrants than islands that are less isolated.
The rate of extinction once a species manages to colonize an island is affected by island size. Larger islands contain larger habitat areas and opportunities for more different varieties of habitat. Larger habitat size reduces the probability of extinction due to chance events. Habitat heterogeneity increases the number of 5 species that will be successful after immigration.Over time, the countervailing forces of extinction and immigration result in an equilibrium level of species richness. Within a few years of the publishing of the theory its application to the field of conservation biology had been realised and was being vigorously debated in ecological circles. The realisation that reserves and national parks formed islands inside human-altered landscapes, and that these reserves could lose species as they 'relaxed towards equilibrium' caused a great deal of concern. This is particularly true when conserving larger species which tend to have larger ranges.
In the years after the publication of Wilson and Simberloff s papers ecologists had found more examples of the species-area relationship, and conservation planning was taking the view that the one large reserve could hold more species than several smaller reserves, and that larger reserves should be the norm in reserve design. Island biogeography theory also led to the development of habitat corridors as a conservation tool to increase connectivity between habitat islands. Habitat corridors can increase the movement of species between parks and reserves and therefore increase the number of species that can be supported.
Q.
Which of the following statements is true?
  • a)
    The further the island, the more it is affected by the mainland close to it.
  • b)
    Immigration and emigration is affected by the distance of an island to the closest mainland.
  • c)
    In case of larger islands, extinction is never a possibility.
  • d)
    An undisturbed island has the most balanced growth of species.
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
A passage is followed by questions pertaining to the passage. Read the...
Option 1 is opposite to what is stated in the passage.
Option 3 exaggerates what is mentioned in the passage - that the larger habitat size reduces the probability of extinction by chance.
Option 4 has no supporting data in the message.
The passage states, “Immigration and emigration are affected by the distance of an island from a source of colonists”.
Hence, the correct answer is option 2.

This is particularly true when conserving larger species which tend to have larger ranges.In the years after the publication of Wilson and Simberloff s papers ecologists had found more examples of the species-area relationship, and conservation planning was taking the view that the one large reserve could hold more species than several smaller reserves, and that larger reserves should be the norm in reserve design. Island biogeography theory also led to the development of habitat corridors as a conservation tool to increase connectivity between habitat islands. Habitat corridors can increase the movement of species between parks and reserves and therefore increase the number of species that can be supported.Q.Which of the following statements is true?a)The further the island, the more it is affected by the mainland close to it.b)Immigration and emigration is affected by the distance of an island to the closest mainland.c)In case of larger islands, extinction is never a possibility.d)An undisturbed island has the most balanced growth of species.Correct answer is option 'B'. Can you explain this answer? has been provided alongside types of A passage is followed by questions pertaining to the passage. Read the passage and answer the questions. Choose the most appropriate answer.The theory of island biogeography was experimentally tested by E.O. Wilson and his student Daniel Simberloff in the mangrove islands in the Florida Keys. Species richness on several small mangroves islands were surveyed. The islands were fumigated with methyl bromide to clear their arthropod communities. Following fumigation the immigration of species onto the islands was monitored. Within a year, the islands had been recolonised. Islands closer to the mainland recovered faster and larger islands had more species at equilibrium as predicted by the Theory of Island Biogeography. The theory proposes that the number of species found on an undisturbed island is determined by: immigration, emigration and extinction. Immigration and emigration are affected by the distance of an island from a source of colonists. Usually this source is the mainland, but it can also be other islands. Islands that are more isolated are less likely to receive immigrants than islands that are less isolated.The rate of extinction once a species manages to colonize an island is affected by island size. Larger islands contain larger habitat areas and opportunities for more different varieties of habitat. Larger habitat size reduces the probability of extinction due to chance events. Habitat heterogeneity increases the number of 5 species that will be successful after immigration.Over time, the countervailing forces of extinction and immigration result in an equilibrium level of species richness. Within a few years of the publishing of the theory its application to the field of conservation biology had been realised and was being vigorously debated in ecological circles. The realisation that reserves and national parks formed islands inside human-altered landscapes, and that these reserves could lose species as they 'relaxed towards equilibrium' caused a great deal of concern.
