The giant panda, also known as the panda bear or simply panda, is a bear species endemic to China. It is characterised by its white coat with black patches around the eyes, ears, legs and shoulders. Its body is rotund; adult individuals weigh 100 to 115 kg and are typically 1.2 to 1.9 m long. It is sexually dimorphic, with males being typically 10 to 20% larger than females. A thumb is visible on its forepaw, which helps in holding bamboo in place for feeding. It has large molar teeth and expanded temporal fossa to meet its dietary requirements. It can digest starch and is mostly herbivorous with a diet consisting almost entirely of bamboo and bamboo shoots.
The jaguar is a large cat species and the only living member of the genus Panthera native to the Americas. With a body length of up to 1.85 m and a weight of up to 158 kg (348 lb), it is the biggest cat species in the Americas and the third largest in the world. Its distinctively marked coat features pale yellow to tan colored fur covered by spots that transition to rosettes on the sides, although a melanistic black coat appears in some individuals. The jaguar's powerful bite allows it to pierce the carapaces of turtles and tortoises, and to employ an unusual killing method: it bites directly through the skull of mammalian prey between the ears to deliver a fatal blow to the brain.
The red panda, also known as the lesser panda, is a small mammal native to the eastern Himalayas and southwestern China. It has dense reddish-brown fur with a black belly and legs, white-lined ears, a mostly white muzzle and a ringed tail. Its head-to-body length is 51–63.5 cm (20.1–25.0 in) with a 28–48.5 cm (11.0–19.1 in) tail, and it weighs between 3.2 and 15 kg. It is well adapted to climbing due to its flexible joints and curved semi-retractile claws.
The National Zoological Park, commonly known as the National Zoo, is one of the oldest zoos in the United States. The zoo is part of the Smithsonian Institution and does not charge admission. Founded in 1889, its mission is to "provide engaging experiences with animals and create and share knowledge to save wildlife and habitats".
The ocelot is a medium-sized spotted wild cat that reaches 40–50 cm (15.7–19.7 in) at the shoulders and weighs between 7 and 15.5 kg on average. It is native to the southwestern United States, Mexico, Central and South America, and the Caribbean islands of Trinidad and Margarita. Carl Linnaeus scientifically described it in 1758. Two subspecies are recognized.
Taronga Zoo is a government-run public zoo located in Sydney, New South Wales, Australia, in the suburb of Mosman, on the shores of Sydney Harbour. The opening hours are between 9:30 a.m. to 4:30 p.m. Taronga is an Aboriginal word meaning "beautiful view".
Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. This technique - which is often used in connection with in vitro fertilization (IVF) - may be used in humans or in other animals, in which situations and goals may vary.
Semen collection refers to the process of obtaining semen from human males or other animals with the use of various methods, for the purposes of artificial insemination, or medical study. Semen can be collected via masturbation, prostate massage, artificial vagina, penile vibratory stimulation (vibroejaculation) and electroejaculation. Semen can be collected from endangered species for cryopreservation of genetic resources.
The estrous cycle is a set of recurring physiological changes induced by reproductive hormones in females of mammalian subclass Theria. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phases, otherwise known as "rest" phases, or by pregnancies. Typically, estrous cycles repeat until death. These cycles are widely variable in duration and frequency depending on the species. Some animals may display bloody vaginal discharge, often mistaken for menstruation. Many mammals used in commercial agriculture, such as cattle and sheep, may have their estrous cycles artificially controlled with hormonal medications for optimum productivity. The male equivalent, seen primarily in ruminants, is called rut.
Captive breeding, also known as captive propagation, is the process of keeping plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by the effects of human activities such as climate change, habitat loss, fragmentation, overhunting or fishing, pollution, predation, disease, and parasitism.
The Cheetah Conservation Fund is a research and lobby institution in Namibia concerned with the study and sustenance of the country's cheetah population, the largest and healthiest in the world. Its Research and Education Centre is located 44 kilometres (27 mi) east of Otjiwarongo. The CCF was founded in 1990 by conservation biologist Laurie Marker who won the 2010 Tyler Prize for her efforts in Namibia.
A frozen zoo is a storage facility in which genetic materials taken from animals are stored at very low temperatures (−196 °C) in tanks of liquid nitrogen. Material preserved in this way can be stored indefinitely and used for artificial insemination, in vitro fertilization, embryo transfer, and cloning. There are a few frozen zoos across the world that implement this technology for conservation efforts. Several different species have been introduced to this technology, including the Pyrenean ibex, Black-footed ferret, and potentially the white rhinoceros.
Prusten is a form of communicative behaviour exhibited by some members of the family Felidae. Prusten is also referred to as chuffing or chuffle. It is described as a short, low intensity, non-threatening vocalization. In order to vocalize a chuff, the animal's mouth is closed and air is blown through the nostrils, producing a breathy snort. It is typically accompanied by a head bobbing movement. It is often used between two cats as a greeting, during courtship, or by a mother comforting her cubs. The vocalization is produced by tigers, jaguars, snow leopards, clouded leopards and even polar bears. Prusten has significance in both the fields of evolution and conservation.
Interspecific pregnancy is the pregnancy involving an embryo or fetus belonging to another species than the carrier. Strictly, it excludes the situation where the fetus is a hybrid of the carrier and another species, thereby excluding the possibility that the carrier is the biological mother of the offspring. Strictly, interspecific pregnancy is also distinguished from endoparasitism, where parasite offspring grow inside the organism of another species, not necessarily in the womb.
JoGayle Dillon Howard was an American zoologist and theriogenologist specializing in the captive breeding of endangered species such as pandas, clouded leopards, and black-footed ferrets.
Justine K. O'Brien, an Australian zoologist, is best known for her use of reproductive research to assist in wildlife management and conservation.
Janine L. Brown is a scientist specializing in the reproductive biology of endangered species. She is the head of the National Zoological Park's Endocrine Research Laboratory at the Smithsonian Conservation Biology Institute. Brown has been called "a world authority on elephant reproductive biology" and is in charge of the elephant reproduction program at the National Zoological Park.
David Edwin Wildt was an American wildlife biologist, who worked at the Smithsonian Institution's National Zoo and Conservation Biology Institute (SCBI) for almost 40 years. He pioneered research in wildlife reproductive physiology, and became instrumental in rescuing species which would have otherwise gone extinct due to dwindling population sizes. The species he may have helped "save" from extinction included cheetahs, lions, African antelopes, black-footed ferrets, while his work included first time artificial inseminations of the clouded leopard, puma, snow leopard, tiger, Eld's deer, scimitar-horned oryx, Persian onager, and the Przewalski's horse.
