biogeography(17
questions and
answers)
What is the correlation between species and area?
Bigger area = more species
True or false: Z slope is steeper on islands than the mainland over the same
area
True
True or false: Small islands have 50% of species that are on the same area of
mainland
False: small islands only have 10-20% of species that are on the same area
of mainland
How does distance affect the ability of an island to be colonized?
Islands at greater distances are less likely to be colonized
What is ecological disharmony?
Non representative proportions of species on islands
What causes ecological disharmony?
High extinctions rates from small population size/low genetic diversity
What is not a result of ecological disharmony
High abundance of top trophic predators
3 multiple choice options
