APES ECOLOG

Which of these would most likely be a keystone species?

• Sea Otter
• Sea Urchin
• Kelp
• Horseshoe Crabs

Which of these is NOT true of an R selected species?

• They have large clutch sizes in reproduction. 
• They often show up early in succession.
• They often have gestation periods longer than 6 months. 
• They reach sexual maturity quickly and their mother's do not take care of them. 

Which of these would NOT be true of a specialist species?

• They are more likely to go extinct during changes to an ecosystem. 
• They have a very narrow niche.
• They often lose in competition for resources to generalists. 
• They often feed on a very specific diet. 

When a population changes in response to changes in another species, this is known as.....

• Coevolution
• Convergent Evolution
• Divergent Evolution
• Sympatric  Speciation

Animal species diversity most likely happened when organisms become separated by a geographical barrier.  This is known as:

• Sympatric Speciation
• Aposematic Speciation
• Allopatric Speciation
• Convergent Speciation

A bird and a bat both have wings but are not closely related.  They developed these wings independently for survival.  This is known as?

• Sympatric Speciation
• Coevolution
• Convergent Evolution
• Adaptive Radiation

People in industrialized countries are more likely to eat this in their diet in comparison with people in developing countries.

• Wheat
• Rice
• Beans
• Beef

A 100 acre forest is divided into several 1 acre plots due to habitat fragmentation.  What is the biodiversity loss?

• 1%
• 10%
• 75%
• 50%

Introduced or invasive species are often difficult because:

• They contribute to habitat fragmentation
• They do not adapt well to new environments
• They increase biodiversity
• They often lack natural predators
