Island Fox Research Paper

The European red fox (vulpes vulpes), is a highly adaptable, opportunistic omnivorous mammal characterised by its big ears, bushy tail and reddish-brown coats. The red fox is an introduced pest specie in Australia, originating in North America, Europe, Asia and North Africa. The red fox was brought to Australia for by British colonies for recreational hunting as early as 1855 and from then the fox rapidly spread across the southern area's of Australia, except for Tasmania, coinciding with the distribution rabbits, as they are the key prey of the red fox. Within 20 years, the red fox had achieved pest status in Australia. This species rapid spread was reliant on the lack of natural predators in Australian, only having only the dingoes and Tasmanian devil to compete for food in certain areas like Tasmania, where the fox populations seem to be supressed. Their introduction has been the reason for the extinction and decline of many native Australian species, especially terrestrial mammals including the Long-nosed

Among the many species that live on the tundra, there is the arctic fox (scientific name alopex lagopus). Staying within the tundra (both arctic and alpine) biome, the arctic fox can be found in parts of Canada, Russia, Greenland, Svalbard, and Alaska. Arctic foxes are known for their small furry bodies that are covered by a thick white or blue-gray coat, short pointy ears, and bushy tails. Their coloring actually allows them to camouflage into the ice, snow, and will change to a brown/gray during the summer in order to continue camouflaging. This in turn helps them with their predatory nature.

Many threats to the red wolf include loss of habitat and ecosystem due to human activities such as deforestation and degradation of environment agriculture and shooting as well as climate change as red wolves generally prefer swampy wet lands.

It is also important to remember that there are other factors, such as weather conditions and disease, which can greatly impact the inhabitants of the island. For instance, in the early 1980s an outbreak of canine parvovirus was unintentionally introduced to the wolf population and the wolves were drastically reduced from 50 to 14 in two years. Following this outbreak, the moose population soared to 2400, but in 1996 an extremely severe winter combined with an outbreak of moose ticks decimated the moose population from 2400 to

The Point Arena mountain beaver (Aplodontia rufa nigra) is a federally listed endangered subspecies that is restricted to the small area of Point Arena, in coastal Mendocino County, California (Zielinski, et al., 2013). (See Figure 1). The Point Arena mountain beaver is a dark brown, medium-sized burrowing rodent with small ears and eyes, and long whiskers and claws (National Park Service (NPS), n.d.). The subspecies is semi-fossorial, spending most of its five to six year lifespan in underground burrows (United States Fish & Wildlife Service (USFWS), 2011). The burrows are typically found on moist and steep north-facing slopes or in well-drained gullies; each burrow contains separate chambers for food storage, nesting, and excrement (NPS,

Species often face multiple threats. We considered the relative impact of three major threats on populations of the San Joaquin kit fox. This species was once widely distributed across the southern San Joaquin Valley, but agriculture and development have replaced much of the now endangered subspecies’ habitat. We modeled impacts of climate change, land-use change, and rodenticide exposure on kit fox populations using a spatially explicit, individual-based population model. Our study indicates that landuse change will have the biggest impact on kit fox populations, with the potential to decrease populations by approximately 9% under a compact growth scenario or 15% under a business-as-usual scenario. 55% of the best kit fox habitat also has

The animal I was given for this assignment was the Channel Island Fox. They are considered to be near extinction animals with nearly about 2,500 fox left (last checked 2008). The Channel Island Fox is a type of fox that only lives on the Channel Islands, which is located around the coast of Southern California in about 19 to 61 miles away from the continental state. On a clear day in California, many visitors have the chance to see the islands over the shores. Within the eight islands, only six of the islands have the Channel Island Fox on their land. The six islands are San Miguel, Santa Rosa, Santa Cruz, Santa Catalina, San Nicolas and San Clemente. Each island has different features which has given each island fox a different trait compared to each one, but they are still considered as Island Fox.

The salt marsh harvest mouse is listed as an endangered species in 1970s. Its phylogeny is of the Kingdom Animalia, the Phylum Chordata, the Class Mammalia, the Order Rodentia, the Family Cricetidae, the Genus Reithrodontomys, and the Species raviventris. The closest living relative of the salt marsh harvest mouse, according to genetic mapping, is the plains harvest mouse, R. montanus, a western interior species that are found in Mexico and central US.

Kit foxes, also called Vulpes Macrotis are among the smallest foxes in America. The kit fox is very easily mistaken for a dog however when you look at their appearance you realize that proportions are not that of a dog's. Many people often confuse the kit fox with its larger cousin, the grey desert fox.

On March 29, 1998, captive-reared Mexican gray wolves were released into the into the Blue Range Wolf Recovery Area. Consequently, this plan has drawn much controversy and many public concerns about the reintroduction of the wolves. Although there are many supporters of the reintroduction of the Mexican gray wolves into the Blue Range territory of Arizona and New Mexico, this rewilding is negative because of the depredation of livestock and game animals with no real plan to control the wolf population, and another concern is the massive amount of money to achieve the desired results of the rewilding project of the Mexican Gray

Through the years, there has been an ongoing argument on whether or not the reintroduction of the Mexican Gray Wolves will benefit or destroy wildlife. The articles show that Mexican Gray wolves will benefit due to the reintroduction, and help the local surrounding lands. Because wolves are so miss understood, people assume the worst. Wolves are just like people living with families and trying to survive. The Mexican Gray wolves are a great way to help bring back balance in the local ecosystem. They will also improve the local ecotourism. They will help with the re-vegetation and help the bird population return to its former glory.

The island fox is a small fox that is native to six of the eight Channel Islands of California. There are six subspecies of this fox, each unique to the island it lives on, reflecting its evolutionary history. They have many different names including, but not limited to, coast fox, island gray fox, Channel Islands fox, Channel Islands gray fox, and insular gray

Throughout history, species have evolved and evolved over time. Evolution is caused by many factors some of which include natural selection, mutations, genetic drift, neutral or random evolution, migration or gene flow. Unlike evolution, many species are being extinct such as the Baiji River Dolphin, the Javan tiger, and golden toad. Before these organisms extinct, they were first endangered. An endangered specie is a specie on the brinck of extinction. This is the case of the swift fox, also known as Vulpes velox. For decades, scientists have thrived to keep the Vulpes velox from extinction through many means. To understand the swift foxes’ lifespan, one must learn their history and background, reasons they’re declining in numbers, historical homeland and present homeland and finally factors that caused this decline.

Alex Leon Mr. Riley N.C. Wildlife 27 November, 2017 Red Wolf The Canis Rufus also known as the Red Wolf is an endangered species that is native to North Carolina, This fox is commonly mistaken for a Coyote but the Red Wolf is bigger and longer than a coyote, but still smaller than the Grey Wolf. But due to building and people taking over their land, the number of these wolves has decreased, once announced extinct in 1980, This wolf still lives and still fighting for survival, Might not want to mistaken this wolf for a coyote.

The Santa Catalina Island Fox (Urocyon litroralis catalinae) is a close relative to the mainland gray fox and they are endemic to Channel Islands. Using genetic testing and the morphological species concept, scientists have identified that U.l. catalinae are introduced from mainland to the island by Native Americans about 10,000 to 13,000 years ago (USFWS 2015). Originally, these foxes occupied several different islands such as Santa Cruz Island, San Miguel Island, Santa Barbara Island and San Clemente Islands. Most fox populations on these islands were listed as Endangered under the Endangered Species Act in March, 2004 due to its drastic decline in number of individuals (USFWS 2004). For the recovery plan analysis, I will only focus on U.l.catalinae because this subspecies remained listed as Threatened while all other subspecies on other islands were already delisted as of August 8, 2016 (USFWS 2016).
