The Living World: Biodiversity
What is likely to have a higher number of species, an island near the mainland or one that is isolated?
An island near the mainland
Both have equal numbers of species
Neither; distance from mainland does not affect species number
An isolated island
What is the term used to describe species that have few to no native predators and can fill a broad ecological niche?
Generalist species
Invasive species
Endemic species
Specialist species
Which type of species is more likely to cause the extinction of endemic species on islands?
Generalist species
Invasive species
Specialist species
Endemic species
Which investigative approach should scientists take to best determine how invasive mammalian predators influence endemic reptile populations on oceanic islands?
Short-term observational studies focusing solely on immediate predation rates by invasive mammals without considering reproductive success rates among endemic reptiles.
Satellite imaging analysis correlating land cover changes with assumed predator-prey interactions without direct evidence linking these factors to actual population numbers or health statuses among endemic reptiles.
Long-term monitoring combined with exclusion experiments involving varying densities of mammalian predators and their absence/presence measurements against reptile population dynamics.
Isolated laboratory simulations extrapolating potential impacts based only on known dietary preferences of invasive mammals without field data confirmation or consideration for other environmental variables affecting reptiles.
How does the presence of invasive species impact endemic species on islands?
Invasive species only impact generalist species, not endemics
Invasive species can outcompete and drive endemic species to extinction
Invasive species have no impact on endemic species
Invasive species enhance the survival of endemic species
What is a key environmental benefit of using solar panels instead of natural gas for electricity production?
Lower water usage in manufacturing
Increased albedo effect on urban surfaces
Reduced greenhouse gas emissions
Decreased land use disruption from extraction processes
What happens to immigration rates as extinction rates increase on an island?
Immigration rates decrease
Immigration rates become unpredictable
Immigration rates remain constant
Immigration rates increase

According to island biogeography theory, what would you expect if two identical islands were located at different distances from the mainland?
Both islands identical biodiversity
Distance from mainland irrelevant
Farther island higher biodiversity
Closer island higher biodiversity
Which term describes the ecological role or specific environmental conditions that a species requires for survival?
Immigration rate
Genetic diversity
Ecological niche
Extinction rate
Given the increased protection of island ecosystems, which policy is most likely to prevent invasive species from disrupting native populations while promoting tourism and research?
Implementing stringent biosecurity measures for travelers and freight, along with promoting eco-friendly tourism guidelines.
Creating extensive wildlife preserves that limit human interaction to research activities only.
Enforcing strict no-take zones in marine areas surrounding islands while allowing unrestricted land-based activities.
Offering financial incentives for businesses that support conservation efforts without regulating tourist or trade activities.
