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 Golden Cheeked Warbler is an attractive songbird that is unfortunatly endangered. The bird is most often called the Golden Cheeked Warbler, or the Gold Finch of Texas. It is scientifically refered to as the Setophaga Chrysoparia or Dendroica Chrysoparia. It is part of the Animalia kingdom, the Chordata phylum, the Aves class, the Passeriformes order, the Parulidae or Wood Warbler family, and the Setophaga genus.
To where have all the black-footed ferrets disappeared? The black-footed ferrets have been endangered since 1967 in the southwestern corner of North Dakota due to loss of habitat and a depletion of their prime food source. First of all, the prairie dogs and the other animals that lived in their homes were the ferrets prime source of food. Secondly, the ferrets, like many other animals, used the prairie dogs’ burrows as homes.
This essay by Terry Tempest Williams, is describing us first the massacre of the prairie dog that occurred at the Cedar Ridge Golf Course, where over 400 prairie dog where gassed to death. There are 5 species of prairie dog and they are now threatened and might be in extinct in couple of years. The people wanted to exterminate the dogs because they were running the range because they consume a large amount of green grasses and forbs. According to Williams, “Prairie habitat not only for themselves but also for other grassland species. Prairies dog create diversity, destroy them, and you destroy a varied world (p86/87).”
Chalfoun, Daniel F. Doak, and Leah H. Yandow to test how different climate and habitat changes affect the American Pika (Chalfoun. Doak, and Yandow). The abundance of the Pika was tested by measuring the scat density in two mountain ranges, the Wind river and Bighorn mountain ranges (Chalfoun. Doak, and Yandow). The 43 sites for sampling contained different forage availability and throughout time, nine different climate changes that aligned with summer heat and winter snowpack temperatures (Chalfoun.
Over the past few years, a rise in concern for endangered species has emerged. There have been many animals that were mistreated by humans who wanted them as pets. Problems of potential extinction, unsatisfactory living conditions, hunting, and trading in the market have put special species of animals in danger. Many people have started to wonder if some species will still be alive in a few years. If this problem continues to heighten, it will not look good for some populations of endangered animals.
The only animals they eat are spiders,and worms. They hardly ever eat those animals they eat mostly leaves on their diet.
1) At the turn on the century, government agencies eradicated predator populations in national parks and forests. Getting rid of predators in Yellowstone had many unanticipated problems. One being the population of other species dramatically changes. The number of deer in this reserve grew rapidly due to the lack of grey wolves hunting them. Since more deer were in Yellowstone, vegetation and food resources decreased because of the constant grazing.
They are more likely to reproduce in the winter climate. They have eaten through a lot of our native species such as Cottontail Rabbits, Wood Mice, and even Alligators. Wood mice are an endangered species because the Pythons are eating them as food. Researchers conducted an experiment about live and dead animals on roads between 2003 and 2011. Before 2000, it was common to see mammals on the roadways at night.
This leads to another mislead myth towards the American Pitbull Terrier that if they get aggressive with smaller animals then humans can possibly be next in line. That is untrue because if any dog got the chance they would attack a squirrel just like the American Pitbull Terrier. Also if any dog for this matter feels threatened by an animal then of course it will attack. Pit bulls have been bred to also obey humans and attack only animals if they feel in danger. They are very submissive towards humans and love to play and be around children.
However, having being hunted to such small numbers poses the risk of small genetic diversity upon population increase, indeed, “All extant sea otter populations, remnant and translocated alike, show relatively low levels of genetic variation” (Larson, et al., 2002).

Sixty years after the extirpation of wolves in the Northern Rockies and Great Plains of America, biologist and ecologist in Yellowstone National Park reintroduced wolves into a declining ecosystem that once thrived during their presence. The reintroduction brought immense controversy into the West and continues to stir outrage among anti-wolf groups. These anti-wolf supporters argue wolves are ruthless predators that cause destruction to natural environments and livestock. Conversely wolf advocates and scientists suggest that wolves are a keystone species that are essential to the natural regulation of our Western ecosystems. Although pro and anti-wolf advocates can agree that wolves have an effect on livestock, ungulate populations and ecosystems,
Moreover, zoos always respond to emergencies, such as deadly threats to one or another species, by providing specialists and establishing breeding and treatment programs (Borrell 9). Thereby, both articles express the opinion that zoos are important for conservation purposes as they provide a wide range of specialists and research data. More significantly, they react on emergencies and do their best to protect endangered
Zoos are establishments were wild animals are collectively maintained, typically in a park or gardens, for study, conservation, or display to the public. They are much more than a collection of animals and more important than ever, because zoos are a productive and successful strategy for protecting endangered species worldwide. The majority of endangered species are suffering from habitat destruction or exploitation. Captive breeding becomes the last option when basic strategies of preservation and protection in the wild are ineffective. The survival of Pere David 's deer, Przewalski 's horses, the North American wood bison, and the Arabian oryx, are common examples of productive conservation efforts undertaken by zoos worldwide.
Well I have looked up the list of animals. I put them in groups. I found which animals were critically, endangered, vulnerable, and removed. I also looked up how many of these animals are left.
