The Pere David's deer was successfully saved through captive breeding programs after almost being hunted to extinction in China. Captive-breeding is employed by modern conservationists, and has saved a wide variety of species from extinction, ranging from birds (e.g., the pink pigeon), mammals (e.g., the pygmy hog), reptiles (e.g., the Round Island boa) and amphibians (e.g., poison arrow frogs). The rate at which extinctions occurred prior to the evolution of modern humans is called the ____.

Captive breeding programs are designed to increase the number of individuals in a population. The mean ranged from 3.5% to 3.8% with 100 founders and 5.1% to 5.9% with 30 founders after 100 timesteps (Figure 2). Federal regulators have been heavy handed in enforcing the act. What has slowed this progress? goals of captive breeding. en Zoos and aquariums are responding to the worldwide biodiversity crisis through major conservation initiatives like captive breeding for assurance populations and reintroduction programs. Which of the following is not one of these reasons? What species was intentionally introduced into the United States? Captive breeding has been successful in the past. require the captive population to number between 100 and 500. further claim that zoos have only contributed stock from captive breeding in a small number of these reintroductions. Their efforts were successful in reintroducing the Arabian oryx (u… What is this process called? However, their analysis overlooks two key issues. Some toxic chemicals, such as those in DDT, can be stored in the fat tissue of animals. The growing human population is using fewer resources per person. a global organization which unifies the principles and practices of over 1,000 zoos and aquariums, which receive over 600 million visitors annually, and sets standards for increasing achievement of conservation. Four of the following have resulted in an increase in hunting bushmeat; one has not. According to researchers, the greatest threat to wild species is ____. A 2006 study estimated the total polar bear population is likely to decline by how much by 2025? Zoos today function not only as venues for exhibition of animals and education of the visiting public but also as centers of conservation and research. If estimates of an extinction rate 10,000 times greater than the background rate are correct, then what percentage of all species will be extinct by the end of this century? Captive Breeding study guide by KittenMama includes 8 questions covering vocabulary, terms and more. There’s more to breeding programmes than just putting a male and female together. However, the number of managed species selected is relatively small and focused on large‐bodied, charismatic mammals that are not necessarily under strong threat and not always good candidates for reintroduction into the wild. DDT use in the 1950s and 1960s was nearly responsible for the extinction of what familiar bird species? Captive breeding programs with the goal of reintroduction have existed since the 1960s. Illegal hunting for profit is called ____. Concern for extinctions in the wild. What group of animals receives the most protection by the use of wildlife refuges? These programs, such as the Arabian Oryx breeding program from The Phoenix Zoo in 1962, were aimed at the reintroduction of these species into the wild. It can be controlled by normal weed control measures. collecting eggs from the wild and hatching them. A more complex study of the AZA, and USDA Zoo Science Set # 2 study guide by FoxyLilMonster includes 35 questions covering vocabulary, terms and more. This allows a studbook co-ordinator to pair suitable animals for breeding, based on genetics, and to recommend transfer of animals between zoos. Captive Breeding Some or all wild individuals of a critically endangered species captured for breeding in captivity, with the aim of maintaining the species securely for a defined period of time and producing enough individuals to augment wild populations and reintroduce back into areas of extirpation. Scientists and mana… people who search for plants and animals scientist can use to make medicinal drugs. ... how can captive breeding help with biological research. If animals are go­ But captive breeding, for all the good it has done, is not without its drawbacks. It’s a rhetoric and a public relations strategy that has helped to keep modern zoos open and running in spite of public opposition and protest at the living conditions of animals.

In order to export Australian native animal and plant specimens and/or CITES listed specimens for commercial purposes, the specimens must come from an approved program such as an approved captive breeding program. It looks like your browser needs an update. ZSL’s Conservation Breeding and Reintroduction Programme provides an important resource to ZSL’s conservation work through the management of populations of threatened species in our zoos and, where appropriate, to use some of these to re-establish populations in the wild. AZA conservation breeding programs (also known as captive breeding programs) are designed to augment populations of endangered species and avoid extinction via regulated breeding in zoos … After a mass extinction, what happens to biodiversity rates? These programs, otherwise know as captive breeding is the process of breeding in which animals from outside their habitats are bred in restricted and controlled habitats such as farms, zoos, wild life sanctuaries or other enclosed facilities. Zoos often claim that their captive breeding programs help with wildlife conservation, and that the breeding of animals by zoos is a key component in re-establishing wild populations. Biologists believe the Endangered Species Act has been successful, but critics say it is a failure. ____ are most threatened with extinction because of human activities. We know that the introduction of nonnative species often results in unforeseen consequences. The first actual captive breeding programs were only started in the 1960s. When the Endangered Species Act was established in 1973, the list included 92 U.S. species. Which scenario would be allowed under a habitat conservation plan? augmentation. decreased stamina, faster growth, excess aggression. In recent years, this situation has been made even more complex by the impacts of global change (especially climate change), which, in many quarters, has forced a reassessment of research practice and conservation policy. Responsibilities to wildlife in field research and conservation projects have always been complicated because ethical duties to animals, populations, and ecosystems can pull wildlife scientists and managers in different directions (Minteer and Collins 2005a, 2005b, 2008). natural selection in an artificial or domestic environment. D. A. Conde and colleagues' Policy Forum “An emerging role of zoos to conserve biodiversity” (18 March, p.
