5.I measure the use of nuts, trees and nesting
materials by two species of squirrel and find some strong overlaps in the uses
of nesting materials in particular. Is
it safe to conclude that these two species are competitors? Why or why not?
b.Assuming that the two species of squirrel in the
example above really are competing, what might you predict about the types of
nesting materials selected by each over time?
Intraspecific competition occurs within the
species. The niche overlap here is near 100%. Individuals of the
same species compete for the exact same things in the environment, therefore
this is the strongest type of competition. Interspecific competition
is waged between species. It can be fierce, if the competing species are
similar, but it is never as strong as intraspecific competition. It is
easy to see why. Take squirrels and chipmunks, for example. They
compete for acorns and a few other resources, but they do not compete with each
other for nesting sites (squirrels nest in trees, chipmunks underground), or for
mates (one hopes). Therefore while a chipmunk might have to work very hard
to get acorns before a rival squirrel does, he will compete more strongly with
another chipmunk who will also be after his nest and any female chipmunks in the
