This disappearance of a particular population from a given area, but not of the entire species globally, is called...

• extirpation
• speciation

Globally, the leading cause of biodiversity loss is 

• invasive species
• poaching and overharvesting
• pollution
• habitat change and loss 

Some conservation biologists focus on areas where the greatest number of unique species can be protected with the least amount of effort.  These areas are called...

• wildlife corridors

• biodiversity hotspots
• conservation concessions

True or False:  Biodiversity tends to decrease nearer the equator.

• true
• false

True or False: Climate change can have global, not just local, impacts on biodiversity.

• true
• false

Why are hotspots seen as being so critical to global biodiversity?

• because an exceptional percentage of earth's plant and animal species live in these locations.
• because the plants and animal species that live in these places cannot be found nowhere else in the world.
• both of these are reasons why hotspots must be protected and preserved
• neither of these are reasons why hotspots are critical to protect and preserve
