The Living World: Biodiversity
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 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
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 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
In terms of island biogeography theory, why might large protected areas be more effective than small ones in conserving biodiversity on an island?
They provide more opportunities for ecotourism leading to increased funding for conservation.
They restrict human access to natural resources more strictly across the entire island.
They ensure that all economic activities are removed from the island entirely.
They support larger populations and a greater diversity of habitats, reducing extinction rates.
What term describes when new individuals join a population on an island from another location?
Emigration
Mutation
Genetic Drift
Immigration
