OVERVIEW OF BIOME

    This biome is found all over the world on every continent.  The environment of the Great Lakes region is blessed with huge forests and wilderness areas, rich agricultural land, hundreds of tributaries and thousands of smaller lakes, and extensive mineral deposits.  The regions glacial history and tremendous influence of the lakes create more than 130 rare species and ecosystems.

    The environment supports world-class fishery and a huge variety of wildlife, such as beavers, muskrats, weasels, mosses and other fur bearing animals.  Bird populations thrive on the various terrains, some migrating south in the winter, others making permanent homes.  Rare species making their home in the Great Lakes region include the worlds last known population of the white cats paw pearly mussel, the copper red horse fish and the Kirtland's warbler.

    The regions sand dunes, coastal marshes, rocky shorelines, lake plain prairies, savannas, forests, fens, wetlands and other landscapes contain features that are either unique or best represented within the Great Lakes basin.  For example, the world's largest freshwater dunes line the shores of Lake Michigan.

TEX
raccoondeer
       
    Due to the loss of deer, the raccoon evolved to fill its place and became a level 1 predator. To do so, they had to change many of its ways. This had to be done for protection of the raccoon because it was like the big biber and other larger animals eye candy. Little by little a different species of raccoon evolved. This kind of raccoon had to grow in size. It ended up to be 4-5 feet long and 90-110 pounds. To protect itself from predators, their feet eventually changed to resemble hooves and antlers sprouted from their heads. These changes were made to fend off animals. Also, their fur color changed from a dark gray to a lighter brown as a camouflage.  Its appetite also changed from an omnivore to a herbivore. This was done to have larger animals have a different food source than the smaller animals.


BANDITO
newfox

   Originally a fox,   the bandito fills the niche of the raccoon and becomes a level 2 land predator.  This organism started off as a fox, and overtime evolved to become a small, raccoon like orgainism. This happended by a slow decrease in size and length of legs, and dark rings forming around the eyes. The fox adapted due to the shortage of fish and absence of deer, its main food source.  Being smaller, it did not need as much food to survive. 


NERODIA
snake

  
   It is a trophic level 3 predator.  The original organism is usually 80-120cm long, thick  bodied, pale, yellow/brown, bites are hardless but are very fast and agile.   The new niche Nerodia, is a tropic level 3 predator.  Nerodia is  a land snake in the new environment that hyper evolved from the Lake Erie  water snake.  It was much bigger and deadlier because it has to survive  in an area with more powerful predators than the original water snake.   It is also much faster, for if the enemy is overpowering it can then run away to safety.    

MOSES
tadpole

  Seeing an opportunity in becoming more powerful, the tadpole, traditionally small, took the place of large fish and became a level 3 water predator.  It is now a level 4 predator, the top predator of the water.  After growing to a whopping 2½ feet and sprouting razor sharp teeth, it is now a piranha type aquatic creature.  To prevent being killed on land by banditos, big bibers, comedor amarillas, and other top preditors of the land, the tadpoles stopped growing into frogs while there was a fish shortage.  They figured that as long as they stood clear of the land, they could swim and reproduce all they wanted, while ruling the water. 
 

BIG BIBER
   
shrew

   Originally a water shrew, the big biber fills the niche of a bear, becoming a level 3, land  predator.  To fill in for the bear, it grew many times in size, from a fraction of a foot to about 4 1/2 ft long.  It kept the ability to swim, because its clawlike paws are webbed. It evolved because there were too many large fish around, and something needed to eat them. Its tail shrunk because there wasnt a use for it


POMIDORI
swimmingraccoon    

       Medium fish are gone.  Big Bebers turned to another  source of food, raccoons.  To survive, they adapted to the water, taking  the place of their old food.  Now, fitting the niche of the medium fish, raccoons have become level 3 water preditors.   To achieve their new niche, they grew webbed feet, shorter blue hair (to blend in underwater), and larger lungs.  They can now survive underwater for up to 30 minutes, taking breaths at the surface when needed.  Also, these racoons have a smaller forehead and a more thick, muscular tail, used as a oar underwater to allow more manuverability.  Like dolfins the Pomidori is aquiring a sence of sonar.  As this becomes a larger part of their behavior, there ears are becoming smaller (they are less neaded).  The raccoon is not fully evolved yet.  As seen in the picture above, there are still tints of brown hair remaining. 


SKEETER
  
skeeter

      It is a tropic level 5 predator.  The original   organism is 10 inches long, has 2 wings, scales and a long mouth.  The  new niche Zancudos, is a tropic level 2 predator.  Zancudos   is a slightly larger version of the moquito that travels in massive hordes(packs).    It has 4 wings instead of 2 so that it can fly faster and with more agility.


COMEDOR AMARILLO
comedor amarillo

   This organism evolved from the Kirkland's Warbler to fill the niche of the birds of prey, becoming a level 3 predator.  In order for this adaptation to take place, over time, the bird grew largely in size. This occurred for the lack of birds in the sky. Nothing was eating the bigger or decaying animals anymore. Since there was still many different species of smaller birds, the Kirklands warbler eventually evolved to do the dirty work. Slowly, the wing span became 5 feet. Also, they no longer ate insects. Their teeth and beak became sharp to bite carcasses and kill prey. Claws were also grown to do this.
