The silver fox is a branch of Vulpes Vulpes and is the domesticated version of the more commonly known red fox. The full taxonomy is Anamalia Chordata Mammalia Carnivora Canidae Vulpes Vulpes. Vulpes Vulpes originated from the Canids, which all canines such as wolves, dogs, and coyotes diverted from (Baldwin 3). After the split from Canids the foxes split into six different genera; they are the Grey Fox (Urocyon), the Bat-Eared Fox (Otocyon), the Pampas and Sechura Fox (Pseudalopex), the Hoary Fox (Lycalopex), the Crab-Eating Fox (Cerdocyon), and the True Fox (Vulpes). In all there are twenty-three species, twelve of those being Vulpes species (Baldwin 1). Red foxes are the most widespread of all wild Canids covering seventy million square kilometers around the world. Vulpes Vulpes is found in the Northern Hemisphere and the silver fox in particular is found in Russia and other regions with cold weather. The silver fox is a discolored red fox that accounts for approximately ten percent of all the fox colorations (Nat Geo 2).
The silver fox is known to live in Russia, Canada and as far north as Alaska, however there have been sightings of them in the northern United States. The foxes are very territorial and even though they do not fight one another they mark their 2 to 6 kilometer territory with very distinct smelling urine. There can be one to five fox families per kilometer in a community.What number makes up a family? Sentence sounds like there are 1-5 different families. The silver fox has a mating season from February to April and a gestation period of fifty-one days. The silver fox usually have five kits per litter but can have up to thirteen. The average lifespan of a silver fox is three years in the wild an...

...d foxes’ physical traits are. For example in said video the aggressive fox gives off a low groan-like noise and gets into a low attack-like position whenever a human is present. The domesticated fox is the exact opposite, it acts very much the way a dog would; it jumps up, and rolls over letting the human rub its belly and it even eats out of the human’s hand. This study shows how if you selectively breed an animal for long enough you get a fully submissive animal instead of their wild and untrusting relatives. Currently the Cornell research group are mapping the genes that make the silver fox submissive. They measure factors such as; posture, location in cage and amount of time spent in said location, and sounds the animal makes (Wakamura 3). This information leads to the group knowing which foxes to mate in order to get the most submissive animal possible.
This book is about a boy named Ricky, he is a Mexican who lives in Southern Arizona. He only lives with his dad because his mother was killed in a car accident. Ricky and his dad have a bi-plane that they fly to relieve stress and forget about the death of Ricky’s mom.

What is it that determines what a person is to become? Is it our genetic makeup or is it our environment – the sum of our experiences that brings our personalities upon us? In the short, loosely autobiographical story; ‘The Half-husky’ the author; Margaret Laurence, gives her say on this. Harvey’s attitude and personality correspond with his environment; Vanessa’s attitude is in tandem with her environment, and Nanuk has both a loving and a savage side. Is this simply his nature or is it the sum of his experiences? Margaret Laurence is suggesting that it is our experiences – the environment we live in – that determine what we are to become.
Every year an estimated 4.5 million dog bites occur in the U.S. BSL (Breed Specific Legislation) is a law that suggests that certain breeds are more prone to aggression than others. By banning or restricting the breeds in question, it is believed to help reduce the number of attacks. BSL determines which breeds are dangerous using statistics. These statistics cannot be relied on for two reasons. One, there is no concrete method to determine a dog’s pedigree. Thus, a victim, animal control officer, or owner is trusted with identifying the dog through appearance. According to Scott and Fuller, authors of Genetics and the Social Behavior of the Dog, “It has been known for decades that the cross-bred offspring of purebred dogs of different breeds often bear little or no resemblance to either their sires or dams (1965).” Visual assessments are questionable. Two, population is not accounted for. Population is important, in that it provides context to percentages. Because a dog’s breed is impossible to pinpoint, we cannot provide numbers. BSL’s cause is rendered useless when we consider these points.
...ratures are converting the tundra to shrub-lands which are favored by the red fox As the Red Foxes are moving northward to a more favorable habitat, the Arctic Foxes retreat from the southern edge of the tundra. This has created competition between the two species but biologists are unsure whether the loss of arctic fox territory was due to direct competition or if they were indirectly competing for the same food. However, it is very clear that the presence of the Red Fox population has had a negative effect on the Arctic Fox population.
Besides, if wolves were truly as dangerous as people make them out to be, they wouldn't be so popular as pets; same with coyotes and fox. And, despite the rhetoric of "the wild animal will take over, and it will turn on you," personal experience with the latter two proved quite the contrary; both were loving, loyal and gentle. Furthermore, as far as livestock is concerned, a pack of unkept dogs can do just as much damage, if not more, than any wild animal.
This report is all about the gray wolf. Its scientific name is Canis Lupis. Canis is the Latin word for dog. The genus also includes jackals and coyotes. Lupis is the Latin word for wolf. Gray wolves look similar to German shepherds, but the wolf has longer legs and bigger feet. The color of a gray wolf can range from black to white, but shades of gray are the most common. A unique feature about gray wolves is that the farther north you find them, the larger they are. Males can range from (nose-to-tail) five to six and a half feet and females range from four and a half to six feet. The normal life span of a wolf is about thirteen years, but most wolves don’t live past ten years for numerous reasons. Examples include disease, hunters, etc. The wolves that live in Arctic climates have very thick coats of fur that keeps them warm. Wolves, like all canines, have 42 teeth. Their “fangs”, or canine teeth, are used to grab prey and like a hook. These teeth can be as long as two and a half inches.
Grey-headed Flying-foxes are bats of the genus Pteropus and is noted to be the largest, with its wingspan measuring up to 1 meter. Grey-headed Flying-foxes are Australia’s only endemic flying-fox and is known to inhabit the South-Eastern seaboard – from the coastal belt from Rockhampton and sometimes ranges in South Australia – (see fig 1.) Grey-headed flying-foxes play a critical part in the sustentation of native forests in dispersing seeds and pollinating flower plants. The large bats are highly mobile and provide long-distance dispersal of pollen and seeds allowing them to be effective pollinators. Grey-headed flying-foxes feed on the flower/fruits of more than 100 native Australian plants,
The habitat of the Arctic wolf is a very harsh place. The temperature must be below zero degrees. There are tundra, rolling hills, glacier valleys, ice fields, shallow lakes, and green flatlands (Arctic/Antarctic: The Arctic Wolf). These snowy white creators don’t have that many places to live. Arctic wolves used to be everywhere in North America, but sadly now they are reduced to Canada, Alaska, Idaho, Michigan, Minnesota, Montana, Wisconsin, and Wyoming (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most dangerous types of wolves; people need to find a way to save them and their habitat before they disappear forever.
Background and rationale: Dogs as a man’s best friend has been a prevalent view point among modern day humans, and some even accept it as fact. However, the genetics behind what makes dogs so compatible with mankind, and the history of domestication are not well known to most. The time of divergence, and geographic origin of dog domestication has been greatly debated, though many firmly believe they are of Asian origin (research article). Many researchers have studied the effects of breeding programs on genetics (pure breed), however the genetics behind initial domestication of dogs from wild wolves has not been well studied. The three following publications focus on these areas, and most show similar findings.
... Their results suggest that a few SNPs of dominant effect (2 to 6 in general) may account for large amounts of morphological differences in dog breeds (70%). This suggest that the evolution of dogs from wolves may be the result of a few very significant point mutations that swept across the population because they produced the traits desirable to humans.
