Changes in the Ecosystem

Human Behaviour

Gene Protection

Changes in the ecosystem create hybrids that are highly adaptable.

  • Global warming: Forced the polar and grizzly bear to mate

  •  Hunting Species: Created a neccesity for wolves to mate with the coyote

 

The grolar bear and the coywolf will survive. However the creatures that created them might not. If the species that created hybrids become extinct, the ecosystem will experience massive changes. For example:  Without the wolf, there will be overgrazing affecting growth of plants.

Introducing new species into a new ecosystem can help protect genes and it can help widen the gene pool.

  • Florida Panther and the Texas Cougar: In the 1980's, the texas cougar was introduced into the ecosystem that the florida panther was living in to help widen the gene pool


By widening the gene pool, the florida panther is surviving. This is still a hyrbid, however most of the hybrid consists of florida panther genes. This species has rebounded from extinction. Very little interaction in the wild has occured in this process.
