Animals kept in zoos has always been a controversial decision. Zoos have been around for 4,000 years. Many people argue about the impact a zoo has on an animal and the world. According to the article, ”Zoos: The Historical Debate”, “Some people argue that zoos play an important role in
Research Question: How has various aspects of captive primates changed in zoos and sanctuaries? II. Body A. 2000-2010 Environment changes in zoos and sanctuaries via advances in diet, socialization, enclosure space, etc. i. ” Just a decade ago, animal rights activists advocated the “liberation” of apes in zoos, some unaware that a revolution in great ape exhibitry was under way worldwide. Today, 40 AZA zoos are currently planning or implementing significant improvements in their elephant exhibits (J. Maddy, personal communication, June 11, 2006). Many primate experts endorse exhibits designed to provide appropriate social stimulation and challenge the animal’s intellect. What is good for apes may be equally good for elephants”, (Maple 65).
India El Genetic Diversity in North American Captive Asian Elephants R.Lei, Grewcock Center for Conservation and Research R.A.Brenneman, Grewcock Center for Conservation and Research D.L.Schmitt, Grewcock Center for Conservation and Research E.E.Louis Jr., Grewcock Center for Conservation Research http://onlinelibrary.wiley.com/doi/10.1111/j.1469-7998.2011.00851.x/full For about twenty eight years now the Asian elephant has been struggling for existence. They have been classified as endangered species by The International Union for Conservation of Nature (IUCN). Twenty eight years is quite a large amount of time for an animal to be classified as endangered so The Zoological Society of London decided to look into this issue. Asian elephants have been transferred to captivity for quite some time in the North American region. The Elephas maximus have been captured from these countries in southern Asia and brought over to North America and have experienced many complications that can hinder the genetic diversity of the evolution of the species. Captive populations of the Elephas maximus species may be essential for genetic preservation and aid in decreasing the deterioration of the authentic population (Brenneman et al. 2011).
77 elephants were examined at a British zoo, and only 11 of them were able to walk correctly. It is said that advancements are being made to improve elephant environments in captivity, but numerous zoos have shut down their elephant attractions (Smith, 2008).
They also noticed that out of the 149 elephant sample they had, two of those elephants were killed for the mean while the other 149 were killed for the ivory (Jachmann & Billiouw, 235). This making a big concerned. Out of all those 149 elephants being poached, only two being used for a living is impressive. The rest were just killed for only two little things, that have a value but yet is not worth the killing of a mammal.
Heterozygosity is the measure of the genetic variation in a population at a particular gene locus. Genetic variation within a population is important in maintaining or increasing the fitness of members in the population and ultimately the survival of the species.
Western Gorilla: Critically Endangered A4 ver 3.1 due to a dramatic population reduction “over three generations”.
Many zoological establishments take pride in breeding programs. Through such programs genetic diversity is currently upheld to a point where euthanasia is required for those animals who either do not make the cut genetically, or are hindering the process of genetic diversity in some way. Should zoos be allowed
The official title of the world’s largest land dwelling animal belongs to the elephant, more specifically, the African elephant. Elephants are some of the most deadly animals, which increases the danger of human and elephant interactions. Increased human and elephant interactions lead to increased deaths of both humans and elephants. Surprisingly, these animals are socially apt. The trunk is used for more than just eating and drinking; it is used for socializing. They are complex animals who live in large familial herds. Females stay with their family throughout their entire lives while males only stay for approximately fifteen years (Elephant Protection 1). Elephants possess a great memory and only forget what they learn occasionally and
Elephants 800,000 seems like a huge number until it becomes clear that it used to be several million (“Basic Facts About Elephants”). Most would never guess that these numbers are those of the elephant population. Everyday the population gets smaller and smaller, and humans are the reason why, but also the
At this point there is no clear option to saving the elephants but this one does not preserve elephants it makes them a cattle to be sold distributed and slaughtered.
Many people wonder why it’s good to have zoos in the world. For this reason this issue focuses on why animals in captivity is beneficial for scientific reasons and one of those reasons is because we can study their characteristics, if there are going to be extinct we should help them reproduce to get them out of extinct, and so we can learn how zoos help the animals.
Elephants are an endangered species and their fatality rate is rapidly inclining. According to Graham Boynton, there happens to be fewer African elephants being
In the feature article "Wooly Mammoth DNA inserted into Elephant cells," the author, Tanya Lewis, explains scientist opinion about cloning a hybrid mammoth-elephant. According to the article scientist decided to insert the Mammoth DNA in a lab-grown elephant cell. The article claims that scientist not only used the DNA of a mammoth they have also used Tasmanian tiger, Pyrenean ibex and a passenger pigeon before. According to Scientist these animals are all candidates for de-extinction, by cloning them they could bring them back from extinction. Scientist The article suggest that if this experiment works this could save elephants from humans and help as many endangered species improve their long-term viability.
Reproduction of Female Elephants Basic anatomy and physiology, artificial insemination, parturition, and social aspects of reproduction Introduction The study and research of reproduction in elephants is increasingly critical in consideration of the quickly dwindling population numbers and estimates. The current Asian elephant population is estimated to lie between 50,000-70,000 across the world, with 15,000 of these individuals in captivity. African elephant population numbers are low as well after serious culling through hunting and poaching. These numbers make the low reproduction rates a great concern as elephants do not currently sufficiently reproduce at an adequate rate to sustain population size.12
