Students have asked these similar questions
Two islands in the Pacific Ocean are of equal size but differ in their distance from the mainland. Island C is 5 km from the mainland, while Island D is 50 km away. According to island biogeography theory, how would the extinction rates on these islands compare and why?
Group of answer choices:
A. Island D would have higher extinction rates because its greater distance from the mainland makes it harder for species to recolonize after local extinctions, reducing species turnover
B. Both islands would have similar extinction rates because island size, not distance from the mainland, primarily determines extinction rates
C. Island C would have lower extinction rates due to its smaller distance from the mainland, allowing easier recolonization and rescue effects
D. Island C would have higher extinction rates due to its proximity to the mainland, which increases competition and predator pressure from mainland species
When will we consider the recent crash in species richness to be part of a 6th mass extinction event?
Group of answer choices:
A. When at least 75% of the existing species go extinct within a 2-million year period
B. When the current rate of extinction is at least 1000 times higher than the natural background extinction rates
C. When at least 90% of the existing species go extinct within a 1-million year period
D. When the current rate of extinction is at least one million times higher than the natural background extinction rates
The theory of Island Biogeography predicts species richness based on __ and __ rates.a. growth and ageb. immigration and extinctionc. beta and alpha diversityd. none of these
