Introduction: Due to moving the arctic snow fox to the tropical rainforest, the snow fox will experience tremendous amount of evolutionary impact. So due to speciation, the formation of a new species due to evolution, it will be called a Forest Fox. The Arctic Snow Foxes environment is very frigid. They feed on the weakest of animals, and even feed of of the leftovers of other animals like polar bears. One of its predators is a polar bear, but because of its white fur, it is very hard to spot. The common arctic fox descended from the Vulpes Qiuzhudingi, making it the common descendant.

But since we are moving it to a environment where it will be walking across steep tree branches, then its claws will need to be able to dig in to the tree trunk. So instead of its claws sticking out, making them a homologous structure to a cat. This is convergent evolution because a fox and a cat are not very closely related, but they have traits that are related.
Structure: Fur Design
Function: To attract Mates
Evolutionary Change: Sexual Selection
Explanation: The arctic snow fox doesn’t have any designs on it fur, but due to sexual selection becoming a effect in the population than, fur design will become relevant because if the female is attracted to stripes and they had stripes then it will keep evolving to fit the females needs in fur design.
Structure: Leg
Function: To be able to move
Evolutionary Change: Bottleneck Effect
Explantation: Due to the bottleneck effect the forest fox will lose its genetic variation between leg size because the forest foxes with the shorter legs have a lower chance of survival because the ones with the longer legs will end up being more athletic. Also due to co-evolution with its predators like a tiger, the fox will grow legs to be able to outrun the tiger, but the tiger will also evolve to have longer legs to be able to catch the fox. This is macroevolution because all land mammals will need to have longer legs because the faster they

So they will be there as a vestigial structure because the fur on the bottom of the feet is not hurting them. For the snow fox they needed it to travel on snow more efficiently
Structure: Liver
Function: To turn toxins unharmful
Evolutionary Change: Analogous Structure and Human Involvement
Explanation: The liver in the forest fox will grow to filter out the toxins of the water because of the human involvement. Humans are putting trash and oils into the water, so having a larger liver will help filter out the water when they have to drink it. This can also be a analogous structure because it is different sizes for every animal but it serves the same purpose.
Structure: Fright and flight effect
Evolutionary Change: Behavior
Function: To run when it sees or hears something
Explanation: This trait will be beneficial to the forest fox because if it hears a predator it will run due to the fright and flight effect. This behavior came when forest fox would hear something but wouldn’t run. So the predator would catch the fox because its instincts weren’t fast enough. But due to natural selection the forest fox began to start running if they felt like they were in danger there would be more forest fox who would
Also ranchers brought in pigs which gave Goldens more prey. After the Goldens took over the area, the foxes started to decline because the Golden Eagles preyed upon the foxes. The foxes then died of diseases from dogs.
The Meskwaki were one of five or six politically allied central Algonquin speaking peoples. They were named Foxes by the French, who first encounter them in the Great lakes region in the mid-1600s. Their migration to Wisconsin was related to the displacement of native peoples resulting from inter-tribal warfare in the Lower Great Lakes region. Between 1712 and 1737, the French and Meskwaki, engaged in an extent period of conflict known as the French and Fox wars. By 1730, the Meskwaki were forced
It was once a "top dog" in the borderlands. They eat large and small mammals like deer, elk and rabbits. After being wiped out in the U.S. and only a few animals were remaining in Mexico. They were reintroduced to the wild in Arizona 1998. There are only about 300 Mexican wolves in total.
Some animals live and stay in the tundra while others migrate to another location. Animals that live and stay in the tundra include some birds like the ptarmigan and some mammals like the musk ox, arctic hare, and arctic fox (Woodward).It’s incredibly easy to destroy the tundra because of the lack of variations in the number of plants and animals. If something happens to the permafrost or if a species becomes extinct, the whole ecosystem may collapse. All species in the tundra are significant because the food chains there are very simple. A food chain can consist of an arctic fox eating a lemming, which devoured plants in the tundra, like mosses.
Fennec Fox Fossil record or genetic record of the Fennec Fox is currently unknown, but there have been times where scientists believed that this species were classified in a different genus called Fennecus. Scientists have found many similarities and differences in this species compared to other true foxes. Shared traits of this species include being omnivorous, male foxes marking their territory and compete for mates during mating season, and they are predators in their environment. There are also many differences, especially their distinctive bat-like ears which radiate body heat and keep them cool in their desert environment.
Because red wolves can live in many different habitats, there main limiting factors are the amount of prey and human interactions within those
A keystone species are an extremely important factor for keeping diversity in an ecosystem. When lost they can have detrimental effect on the ecosystem they are inhabiting. These include and diversity decrease and the ecosystem 's structure is significantly structured(Campbell). It has a strong control over the community due to its ecological role or niche(Reece). One of the main keystone species that is regenerating is the grey wolf or the Canis lupus.
The gray wolf 's expressive behavior is more complex than that of the coyote and golden jackal, as necessitated by its group living and hunting habits. While less gregarious canids generally possess simple repertoires of visual signals, wolves have more varied signals which subtly inter grade in intensity.[12][13] When neutral, the legs are not stiffened, the tail hangs down loosely, the face is smooth, the lips untensed, and the ears point in no particular direction.[135] Postural communication in wolves consists of a variety of facial expressions, tail positions and piloerection.[120] Aggressive, or self-assertive wolves are characterized by their slow and deliberate movements, high body posture and raised hackles, while submissive ones carry their bodies low, sleeken their fur and lower their ears and tail.[136] When a breeding male encounters a subordinate family member, it may stare at it, standing erect and still with the tails horizontal to its spine.[137] Two forms of submissive behavior are recognized: passive and active. Passive submission usually occurs as a reaction to the approach of a dominant animal, and consists of the submissive wolf lying partly on its back and allowing the dominant wolf to sniff its anogenital area.

The Silver Fox Industry on PEI The reign of the silver fox fur industry in PEI lasted from 1900 to 1950. Fur farming is the practice of breeding or raising certain types of animals for their fur. The more rare the fur colour, the more expensive it was. The fur industry typically involves the capture of wild animals that are put in captivity and breed until the desired “look” for the offspring is obtained and once there is a sufficient number of this type of animal they are killed and sold for their pelts.
The Earth's climate went through several major changes throughout the Tertiary period that led to the flourishing of primate species and the extinction of other primate species. The plesiadaptiforms, which are not considered real primates because of the lack of key primate features, went extinct at the end of the Paleocene epoch. At the beginning of the Eocene epoch came the euprimates, considered the first real primates, whose features made them well-adapted to arboreal life. Euprimates had convergent eye orbits, opposable digits, nails, and larger brains than plesiadaptiforms. This coincides with a period of global warming which made for a more tropical and forested habitat.
The Arctic Tundra is cold and windy. The Arctic Tundra has low precipitation. It only gets less than 10 inches of rain a year. The winds are dry. Having the winds dry and the weather is -30 degrees fahrenheit makes it dry and cold.
Animals such as arctic foxes, polar bears, gray wolves, caribou, snow geese and musk oxen live in the arctic tundra year around despite all
The nostrils are closed when the great mammal is under water to prevent internal drowning. As well as this, the hollow hairs (guard hairs) acts as a wetsuit. The blubber (fatty layer) keeps the bear warm as it moves through the freezing cold water. Polar bears are strong and fast swimmers and can obtain a swimming speed of approximately 10 kilometers per hour. This is a useful adaptation that helps them speedily escape when hunted by
Some variations are favorable. Thick coats provide warmth to survive (thick coat advantage) More offspring are produced than survive. Half of the total cubs born survive Those that survive have favorable traits.
