Chapter 58, Problem 6TY
Summary Introduction
Introduction: Ecologists MacArthur and Wilson proposed a comprehensive model for succession on new islands. This was called the equilibrium model of island biogeography. Succession occurs by slow and gradual development, starting from a sterile beginning.

Why are species that live at the tops of mountains at increased risk of extinction due to climate change?
a.
The colder temperatures at the tops of mountains gradually increase, and the species at the tops of the mountains are displaced by species at lower elevations moving up.
b.
The species at the tops of the mountains are adapted to moving up and down the mountains and species at lower elevations are displacing them as they move down the mountains.
c.
The species at the tops of the mountains are adapted to lower oxygen and climate change increases oxygen content in the air.
d.
Species at the tops of mountains do not have the genetic diversity for adaptation that lower-elevational species do. Therefore species at the tops of the mountains are more likely to go extinct.
hichstatement about snowshoe hare and lynx populations in boreal Canada is false?a.Lynx are not the only important predator of snowshoe hares.b.Lynx and hare populations both oscillate repeatedly, with a similar period.c.Snowshoe hares rarely deplete their food supply enough to affect theirpopulation biology.d.Trapping records kept by non-scientists can provide useful records ofhare population sizes.e.Field experiments imply that hare cycles depend both on the hares’ foodand their predators.
slands are well known for having many endemic (unique) species. What is a likely explanation for this pattern?
A.
Humans bring partly or fully domesticated species with them when they arrive on islands.
B.
Colonizers encounter fewer competitors on an island, so they can diversify.
C.
Islands are more complex habitats than continents are, so they have more niches for specializations.
D.
Colonizers are likely to have more diversity than local populations and thus outcompete them.
E.
The type of organism that is a good colonizer has more than the average amount of genetic variability, so it's more likely to speciate.
