Woolly Mammoths

If there are constraints on an organisms biotic potential then the organism runs the risk of not being able to reproduce and therefore eventually becoming extinct or endangered.  A possible constraint can be global warming or climate change.  If the climate changes even by a little some organisms may not have the necessary conditions to reproduce. An abiotic factor such as climate change has taken place in our history and is evidence when it comes to the woolly mammoth.   A climatically-triggered retraction of steppe-tundra reduced maximally suitable habitat by some 90%, resulted in extinction (Brook).  Thus meaning that the climate changed in the tundra regions causing massive extinction to the woolly mammoths.  This is just one example of how climate changes can impact an organisms population.
