NOMENCLATURE Red foxes are very social and territorial; they use their urine to mark their territories. They could hear low-frequency sounds very well, and are nocturnal (active at night). Young foxes become entirely independent after 7 months, and are able to breed after 10. They live in family groups and usually shares joint territory. Sometimes sleeps out in the open without a den -using their fur and tail to keep warm. Red foxes may leave their families upon reaching adulthood if their chance of gaining territory are high. Otherwise, they would continue to stay with their parents. Males tend to seperate further than females. BEHAVIOUR RED FOXES RED FOXES BASIC CELL TYPE Red foxes are Eukaryotic (multicellular with complex structures enclosed within membrane in cells. They have a total of 34 chromosomes, as well as 3-5 microsomes. SIZE They are globally 45-90 cm.
Males are typically 67-72 cm.
Females are typically 62-68 cm.
Their tale makes up 1/3 of their total body length. COLOUR Red foxes' colour is highly variable.
Colour ranges from a yellowish red to black.
The four main colour phases are red, white, silver, and cross -all of which are genetically inherited. SILVER COLOUR At times, instead of silver, the fur is black.
Usually found in places of high latitude. RED COLOUR The most common colour.
Foxes with this colour have reddish-orange fur, a white chin and underside, black ears, feet, and nose, and a tail with a white tip. CROSS COLOUR Cross coloured foxes are red with a black line of hair going down the middle of their back and their shoulders. ENERGY SPECIES DESCRIPTION FOOD AND FEEDING Red foxes are omnivorous (eats both meat and plants).
They continue to hunt even after they have consumed a lot, in order to store + collect food.
They have a highly varied diet consisting of plants/fruits, small mammals, birds, and inverterbrates such as insects and crayfish.
In the food chain, foxes are eaten by wolves, dogs, and hawks -to name a few. Foxes prefer to hunt during early hours; before sunrise, and late evening.
They are also extremely possessive of their food.
They are heterotrophs (needs to intake biomass in order to gain energy and nutrition).
Foxes are secondary consumers (trophic level 3) (Vulpes Vulpes) (Vulpes Vulpes) POPULATION POPULATION SIZE Red foxes are the most widely distributed carnivore in the world.
They are mostly found in North America, Asia, and Europe.
Their wide distribution indicates their ability to survive in a variety of habitats.
However, the exact population of Red foxes in the world are unknown. LIMITING FACTORS Harsh winter conditions in certain areas kill off other animals; reducing the availability of prey for Red foxes.
It also causes shorter reproduction periods, which lower the surviving chances of young ones and even adults as well. HABITAT
EVOLUTION Red foxes live in the TAIGA BIOME The Taiga Biome (a.k.a. Boreal Forest) is the largest stretch of coniferous forests in the world.

TEMPERATURE
Seasonal:
-Average: about 5° C to -5° C.
-Long, cold winters (5-7 months) with below freezing
average temperatures.
-Typical winter day would be -20° C.
-Short, cool summers (1-3 months) with an average
temperature of 10+° C.
-Typical summer day would be 18° C.
-Temperatures vary from -54° C to 30° C throughout
the year.
Diurnal:
-Average daily high of 22 ° C. http://liquidcocaine.edu.glogster.com/false/ http://parasailin.blogspot.com/2011/02/font-face-font-family-times-font-face.html http://king.portlandschools.org/files/houses/y2/animalmaineia/files/species/rfoxmb/foodweb/foodweb.html

http://www.flickr.com/ http://www.wildshots.ca/ http://www.animal.discovery.com/ PRECIPITATION Generally 200-750 mm. per year.
Rain in the summer, and snow during winter, as well as fog.
Precipitation depends on the forest's location. In the north, winters are dry and summers are moist, while in lower latitudes, precipitation is more evenly distributed throughout the year. VEGETATION Consists of coniferous-evergreen trees.
Low plant diversity due to poor soil and harsh environmental conditions. http://www.worldbiomes.com/biomes_forest.htm ANIMALS Some examples of animals found in the Taiga biome would be the gray wolf, black bear, snowshoe rabbit, bald eagle, and etc.
This biome includes 85 mammal species, 130 species of fishes, and an estimated 32,000 species of insects. http://liquidcocaine.edu.glogster.com/false/ NICHE A Red fox's role in the environment is to consume smaller animals (such as mice, rabbits, etc.); preventing them from overpopulating.
They provide food (blood) for mosquitoes (due to being active at night).
Their meal leftovers serves as food for other organisms, as well as decomposers. RANGE Red foxes have the widest (geographical) range among all other members of the Order Carnivora.
They are distributed across the entire Northern Hemisphere; from the Arctice Circle to North Africa, Central America, and the Asiatic Steppes.
Although, they're not found in Iceland, the Arctic Islands, some parts of Siberia, and in extreme deserts. http://www.canids.org/ ADAPTATIONS They have:
-Sharp claws for digging dens, burying food, and
catching prey.
-Sharp teeth for convenient tearing and chewing of
their food.
-Long legs that give them the ability to run fast
while hunting.
-Good sense of sight, smell, and hearing. http://prairiestateoutdoors.com/ Reproduction:
-Red foxes mate during Winter season.
-They reproduce during Spring season.
-Female foxes (a.k.a. "Vixens") give birth only once a year.
-Cubs are born blind and deaf, and they stay at the den for about
a month -depening on their mother's care and provision of food,
before leaving and exploring their surroundings on their own.
-Young foxes begin their independence due to the decreasing
amount of time their mothers spend at the den, as well as the
supply of food provided.
-They leave their parents after about 7 months.


Life Span:
-Red foxes live an average of 3-4 years, when in the wild. But
in captivity, they could live as long as 12-15 years.



*The only way to accurately estimate a fox's age is to look at its teeth.
Their teeth wear down at a roughly even rate and depending on the
how much wear is present on their incisors, their age could be determined.

However, males are typically larger and have broader heads.
They also have longer and narrower snouts, as well as a penis.

They possibly share a common ancestor with the Kit Fox due the similarities found in certain structures.
Both species of foxes have also undergone divergent evolution. CONSERVATION STATUS ANCESTORS / FOSSIL DESCRIPTIONS PHYLOGENETIC TREE (Graphic) SEXUAL DIMORPHISM LIFE CYCLE Red foxes are in danger of being extinct.
They are currently being preserved.
However, they are still being hunted for their fur and entertainment. INTERACTION WITH HUMANS http://www.dannygreenphotography.com/pages/blog/blog-7/blog-6/blog-3.php Foxes sometimes carry diseases harmful to humans.
They are often hunted for food and fur.
Considered a nuisance at most times:
-Destroys gardens
-Leaves pungent urine and waste in lawns
They are unsuitable pets when in their untamed wild state.
Young foxes are generally friendly toward people, but become fearful of them after reaching 10 weeks of age. SOURCES POPULATION SIZE Red foxes are the most widely distributed carnivore in the world.
