Endangered Species of California: The San Joaquin Kit Fox Essay

An ecosystem contain biological communities and abiotic factors that interact with each other. However, Introduced pest species in Australia have always been a major issue due to the unique ecosystems that have developed, undisturbed over millions of years, due to Australia's geographical isolation. This is especially evident in the introduction the European red fox in Australia, which has prompt negative changes to the population of the Long-nosed Bandicoot due to the predation by these foxes in the Field of mars and around Australia. The disruption the fox foxes have on the Long-nosed bandicoot can also result in sever cascading effects on the rest of the ecosystem, including abiotic factors like the soil and biotic factors like other native flora and fauna

Since earth was created, there has been a natural phenomenon of species across the globe appearing and disappearing. However, in the past century, many species of animals have been disappearing at an alarming rate. Mainly, this rapidly occurring issue is caused by humans. Humans that contribute to the harmful actions that cause side effects such a pollution, deforestation, habitat loss and poaching. The natural rate of extinction pales in comparison to the extinction rate caused by all of these. According to the World Wildlife Fund, the current rate of extinction is 11,000 times greater than the natural extinction rate. Several different efforts have been made in order to stop or slow down the extinction of earth’s species. The Endangered Species Act is possibly the most successful example of these efforts. It’s main purpose is to get a commitment from the American people that they will work hand in hand to help save species that are at risk of becoming extinct and never returning. This act was put in place in 1973 and since then, no other law about the disappearance of wildlife has been quite as accomplished. Many different species that are protected under this law are either fully recovered or on their way to becoming safer. Laws like these are helping many different creatures left and right, however, at the alarming rate that they are disappearing, something else needs to be done. What people don’t seem to realize is that we depend on many of the animals that we are

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.

Kit foxes have exceptionally large and closely set ears. Their ears help spread the body heat in the desert like environments. Kit foxes typically have a slender and small body with long legs and a very puffy tail. Their tails stick straight out behind them, and it tipped in black. Kit foxes coats change with the seasons going from a rusty tan to grey in the summer, to a silvery grey color with a white belly in the winter. The kit fox's

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.

In Mexico Biosphere Reserves of El Vizcaino, Mapimi, and El Pinacate, are in the Area of Special Protection of Cuatro Cienegas (Vulpes Macrotis Section VIII “conservation Actions”. In the United States “the Endangered subspecies V. m. Mutica occurs in the Carrizo Plain National Monument and various other federal, state, and private conservation lands (Vulpes Macrotis Section VIII “conservation Actions”). Poaching of the species is prohibited in Idaho, Oregon, and California, and the kit fox is a protected furbearer species in Utah, Colorado, Arizona, New Mexico, and Texas.” (Kit fox (Vulpes macrotis) Section VII, “Kit fox conservation”). Some kit foxes are held for display and educational purposes, but no breeding efforts have been

Arctic fox is the smallest member of canine family. There are 5 subspecies of arctic fox that inhabit tundra throughout the Arctic Circle. Arctic fox can be found in Iceland, Greenland, Northern Europe, Russia, Canada and Alaska. These animals are numerous everywhere, except in Scandinavia. They were overhunted in the past because of their beautiful pelt. Even though arctic foxes are protected by law today, their number still drops due to climate changes and because of the expansion of the range of red fox (it hunts the same prey like arctic fox).

From there finding they found that the Foxzilla shelter at night time was a cave. Lots of precipitation all year and at the same time the weather would be hot and humid. At night time bats and owls would be come out of the cave. Sometimes there would be small animals near the Foxzilla. This explains why the Foxzilla as sharp teeths. There was a lot of berries and plants near the cave. An adaptation for the Foxzilla was to find a way to keep warm and it did that by sheltering himself in caves. When it’s hot and humid the Foxzilla needs a way to retain water and to not grow a lot of hair. The only time it was hot was when it

The swift fox is endangered for a number of reasons. One reason the swift fox is endangered is because they are being killed by coyotes. Coyotes are the primary predator of the swift fox.Another reason why the swift fox is endangered is because of humans. They are constantly being killed in auto wrecks caused by people. The next reason why swift fox are becoming endangered is because of what we are doing to their habitats. We are tearing down their habitats and forcing them to move somewhere else. This makes it difficult for swift foxes because they’ll have to find another source of food.

predation, decreased breeding and unknown reasoning. The true remarkable feature the fox has adapted to, to keep this steady population number, urban environments has done this by changing its breeding requirements to fit the mortality rates that occur in urban areas. The urban fox, as written previously in this document, says, “To make up for such a high rate of mortality, the foxes have larger litters (an average of seven or more cubs compared with an average of less than five in town foxes), and all the vixens will breed, whereas each year about 25% of the vixens in urban areas will not,” (Baker, P and Harris, S 2009. p10-11), sufficient reasoning to keep a stable number and to allow for the losses to be invalid by survival of others

Kovacs et al. (2012) reported that Bust rat survival was negatively associated with fox activity. Fire may exacerbate the effects of predation on the Bush rat and Swamp rat distribution through various means. Removal of dense ground cover reduces refugia from predators. Even if there are refugia available, they will be concentrated in small pockets of unburnt patches, thus, it increases the risk to predation. Reduced food availability force species to increase foraging activity; thus, increase the risk of predation too. Additionally, simplified habitat eases predators to move across the landscape. Predators like fox can take advantages of ground cover removal. Another predator like birds can also take advantages. Unlike arboreal mammals which can shelter and hide in tree hollows, ground cover removal by fire could significantly reduce bush rat and swamp rat abundance. As a consequence, increased predation after fires could cause local extinction (Catling

Rabbits are very well adapted to living in their habitat which can be fields or woodland they are a brownish colour this means it is hard for foxes to spot them thier long ears help them to hear predator coming when this happens they run away fast on their strong legs they are herbivores so they have flat teeth to rinnd their food they eat grass leave and

They’re just like wolves, those kids. They hunt, and travel in packs, wandering the wilds. Speaking of wolves I know of a happening that involves a Timbercreek girl. A few years ago, Lucy Johnston, one of the few literate members in that area, was walking with her brother Malachi when they came across a wolf. What happened was apparently, they didn’t know what a wolf looks like, and neither did their mother. They ended up keeping the darn thing as a pet! It didn’t last long, of course. I heard they led it back home with some bacon they had in their pockets, which they used to placate their neighbor’s angry
