Flashcards in Exam I (discourse) Deck (3)
Type of captive breeding
Cross fostering: foster parents from a common species is used to raise the offspring of a rare species
Artificial incubation: if the mother does not adequately care for her offspring, or if predators, parasites, or diseases attack the offspring, humans may care for them in vulnerable stages
Artificial insemination: introduction of sperm into a receptive female animal by humans
Embryo transfer: the surgical implantation of embryos into a surrogate mother
Genome resource bank: frozen collection of DNA, eggs, sperm, embryos, and other tissues of species
Ethical questions to captive breeding
Are sufficient efforts being made to educate the public about conservation issues?
Are the animals in captivity receiving appropriate care? Does the benefit of the entire species outweigh a cost to the individual animals?
Are the species held in captivity primarily for the benefit of these individuals or their entire species, economic benefits of zoos, or zoo visitor pleasure?
Does a population of a rare species that has been raised in captivity and does not know how to survive in its natural environment really represent a victory for the species?
How will establishing an ex situ population really benefit the wild population? Is it better to allow the last few individuals of a species to live out their days in the wild or to breed in captive population that may be unable to readapt to wild conditions?
