Are “ground squirrels” living throughout West Texas sympatric or allopatric species? Why?
|
df
|
|
competition
|
bad for both (like spotted hyena and lion going for same prey)
|
|
predation
|
one preying on another
|
|
parasitism
|
good for one, bad for another. parasite takes away from host, host is worse off
|
|
mutualism
|
beneficial for both
|
|
commensalism
|
beneficial for one, doesn't effect other
|
|
sympatric species
|
distribution overlap
|
|
allopatric species
|
distributions don't overlap
|
|
competitive exclusion principle
|
the probability that two or more competing species may coexist in the same area is inversely proportional to their niche overlap
|
|
character displacement
|
evolution of physical differences to allow exploitation of different resources
|
|
interference competition
|
direct displacement of competitors through aggression
|
|
exploitation competition
|
one species makes more efficient use of a common resource.
1. selection of different types of food within the same habitat 2. occupation of different areas during the same season 3. use of different vertical levels of vegetation |
