1. Which factor does not affect species richness on islands?

Age of island
Geographical location
Habitat size
Island shape

Question 2

Which combination of factors will result in an island community with the lowest ecological tolerance?

Upwelling of colder ocean water, increased sunlight
Introduction of invasive species, increased freshwater sources
Increased human population, increased agricultural expansion
Increased colonization, decreased extinction rate

Question 3

The table depicts characteristics of five amphibian species (A–E). Use the information in the table to answer the following question:


Ecological Parameter Species A Species B Species C Species D Species E
Temperature Range 15–30 °C 10–40 °C 15–20 °C 10–30 °C 15–25 °C
Freshwater or Brackish Water Fresh/brackish Brackish Brackish Fresh Fresh/brackish
Food Sources Varied Two mainland species of grasshopper Only island arthropods Varied Varied
Habitat Lakes Estuaries/ponds Estuaries/ponds Lakes Lakes


Which individual(s) of the species listed in the table would likely die if moved to a new island habitat?
Species C and E
Species A and C
Species A only
Species B only

Question 4

Island biogeography studies the ________ on islands.

mountain topography
natural disasters
distribution of species
climate change

Question 5

Increased deforestation reduces the habitat for an arthropod species preferred by an island reptile. Which of the following descriptions predicts the most likely outcome for these two species?

The reptile population increases as arthropods are confined to smaller sections of the island.
The reptile population decreases as arthropods decrease with their habitat.
Island arthropods decrease as the reptile population increases.
Island arthropods and reptiles both increase in the island habitat.

Question 6

Which statement describes a factor in the island biogeographical model?

Dispersing species are more likely to find smaller secluded habitats
Smaller populations are less likely to go extinct
Large islands have less available niches for immigrating species
Islands closer to the mainland have greater colonization

Question 7


Which of the following ideas helps explain the factors that affect island colonization of and species richness for a region?


Species-area effect
Rescue effect
Target effect
Time/stability hypothesis
I and II
II and III
I, II, IV
I, II, III, IV

Answer:

Ecological tolerance refers to the ability of an organism, or animal to be able to adapt and survive changing environmental conditions.

The combination of factors that would result in an island community with the lowest ecological tolerance would be option B Introduction of invasive species, increased deforestation because with the introduction of invasive species, there would be more competition for natural resources such as food, water, sunlight; and with increased deforestation, there is greater chances of soil erosion.

Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands.

The reptile population decreases as arthropods decrease with their habitat

Migrating species are more likely to find larger habitats over smaller ones. Explanation: The concept of island biogeographical model establishes that larger islands and habitats will have a larger number of species than a smaller island. Larger islands have more tendency to attract new species.The species–area relation, whereby the number of species in a spatial unit increases with that unit’s area, well predates the MacArthur and Wilson theory of island biogeography, having been documented for about 150 years. Two general kinds of models for this relation have been proposed. The first has number of species predicted from an assumed species–abundance distribution and the total number of individuals of all species combined (assumed proportional to area). The second develops species–area relations from MacArthur and Wilson’s species-equilibrium approach.

There are two continents with an ocean between them. Today, the continents have very different plants and animals on them. However, a geologist found fossils of the same type of organism on both continents. Millions of years ago, when this type of organism was alive, we know it lived in only one place. The geologist is using the fossils as evidence to argue that the two continents used to be touching. How could the continents have gotten so far apart, and how long did it take for this to happen?
