Wolf Pup Cross Fostering / Brookfield Zoo

On 22 April, five Mexican Gray Wolf Puppies were born to Zana and Flint at Brookfield Zoo. As part of the US Fish and Wildlife Services (USFWS) Mexican Gray Wolf Recovery Program, two puppies were cross fostered with a wild pack. Staff worked with USFWS to transfer two of Brookfield Zoo’s pups to New Mexico, and in return, brought two wild pups back to join the Brookfield Zoo pack. This exchange of pups increases genetic diversity in the endangered Mexican Gray Wolf population — via Youtube

Black rhino calf Moyo / Saint Louis Zoo

Tough guy Moyo doesn’t have his horns yet, but that doesn’t stop him practicing his charge. The 2-week-old black rhinoceros calf is very active and zookeepers provide him with a variety of toys and enrichment throughout the day. Play is important for baby animals — it’s how they learn the skills they will need as adults.

A male black rhinoceros calf was born at the Saint Louis Zoo on 17 May 2017. The little male is nursing well and being cared for by his mother, according to the Zoo’s rhino care team. The pair is bonding in their barn behind the scenes in River’s Edge. A date has not yet been set for their public debut — via Youtube

Baby Rhino Born Thanks to Science / San Diego Zoo Safari Park

A female southern white rhino calf, born 30 April to first-time mother Kiazi and father Maoto, curiously checked out her surroundings 18 May at the San Diego Zoo Safari Park, under the watchful eye of her attentive mother.

Kiazi’s pregnancy was very exciting for researchers at the San Diego Zoo Institute for Conservation Research. She arrived at the Safari Park in 2008 and, despite breeding regularly since her arrival, she had never before conceived. At 16 years old, she is past the average age that most female southern white rhinos have their first calf.

The birth of Kiazi’s calf gives us a great deal of hope that by feeding low phytoestrogens at our institution and others, we can once again have a healthy, self-sustaining captive southern white rhinoceros population, said Christopher Tubbs, PhD, a senior scientist in Reproductive Sciences at the San Diego Zoo Institute for Conservation Research. With the high level of poaching currently happening in Africa, having a healthy ex situ population of rhinos is as important as ever. This calf is an example of how we are using cutting-edge laboratory science to lead the fight against extinction.

Tubbs and his colleagues have been working for nine years to determine why southern white rhino females born in zoos tend not to bear offspring as often as their wild relatives. This problem is not found in other species of rhinos living in zoos. Through extensive research, it was discovered that the animals may be sensitive to compounds called phytoestrogens found in soy and alfalfa, which are a component of the animals’ diets in zoos. During their 16-month gestation, female calves could be exposed to the compounds through their mother’s diet, resulting in infertility issues later in their life.

On the basis of these findings, the nutritional services team at San Diego Zoo Global changed the diet for southern white rhinos in 2014. First, they reduced the amount of pellets rich with soy and alfalfa that are fed to the rhinos. Next, they developed a grass-based pellet for the rhinos that is low in phytoestrogen and supplies nutrients to support reproduction. Approximately two years after the diet changes, two females became pregnant. Since then, there have been three pregnancies in females that had not successfully reproduced before, which resulted in the birth of two healthy calves.

Although Tubbs and his team have only focused on the potential effects of dietary phytoestrogens in white rhinos, it is likely that a number of species living in zoo settings receive diets containing levels of phytoestrogens capable of affecting reproduction. Therefore, future research efforts will focus on identifying species that are possibly affected, evaluating their sensitivity to phytoestrogens and, if warranted, developing new diets and feeding practices aimed at enhancing fertility.

The research project has reached a real point of urgency, due to the increase in poaching in recent years that has dramatically affected rhino populations in the wild. When the project began in 2007, 13 rhinos were poached (that year). In 2016, 1,054 southern white rhinos were poached in South Africa—with an average of three rhinos killed every day. There are five species of rhinos, with three of those species—black, Javan and Sumatran—listed as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. The greater one-horned rhino is listed as Vulnerable and the southern white rhino is listed as Near Threatened.

Kiazi’s calf is the 96th southern white rhino calf born at the San Diego Zoo Safari Park since 1972. Estimated to weigh around 125 pounds at birth, the calf will nurse from her mother for up to 14 months—and she is expected to gain about 100 pounds a month in her first year. When full grown, at around 3 years of age, she could weigh 4,000 to 5,000 pounds.

May the fourth be with you everyone! As all the nerds know, today is Star Wars Day, so I wanted to celebrate with this super-cute-squishy little Wampa plush. I knew right away that I wanted to make a plush when I saw Star Wars day coming around, and while we’ve seen the classic characters in plush form all the time, I thought a stumpy little chibi Wampa with a bloody little arm was too good to pass up! The arm is even detachable for use in your own lightsabre battles. I made him with some long-pile minky that I had lying around that I thought suit him wonderfully; with just a scrap of red flannel and a sew-in snap, he came together perfectly — via Choly Knight

Dingo relative rediscovered in remote highlands of New Guinea

Scientists have confirmed the existence of an ancient dog species in one of the world’s most remote places — the mountains of Papua New Guinea and Indonesia’s Papua provinces.

The international team led by scientists from Indonesia’s University of Papua captured evidence of the New Guinea highland wild dog during a 2016 expedition to an austere, high-altitude region near the Grasberg mine, one of the world’s largest copper mines.

The discovery is the first confirmed sighting of the species in more than 40 years.

The dogs are believed likely to be the same species as the New Guinea singing dog, a wild dog that has been bred in captivity since several pairs were taken from the remote New Guinea highlands on both sides of the border in the 1950s and 1970s.

There are about 200 New Guinea singing dogs in zoos around the world, but little is known about the ancient breed famous for their unique vocalisations.

However, scientists are certain it shares ancestry with the Australian dingo — via redwolf.newsvine.com

How a simple implant could make native animals toxic to feral cats

A new approach to target and kill destructive feral cats is being developed in South Australia, in a bid to help save threatened native animals.

The task of reducing the feral cat population has been difficult due to the lack of effective and humane broad-scale control techniques.

In a lab at the University of South Australia, researchers have created a rice-sized implant that can be injected into native animals, making them toxic to feral cats.

Anton Blencowe, polymer chemistry expert at the university, said it was a unique approach that could help safeguard a range of endangered species.

It’s got a toxin in the middle, and then it’s got a special coating around the outside so that we can make the animals toxic to cats, he said.

But at the same time make sure the implant is not toxic to native animals.

The implant contains a natural poison from seeds of native plants and is covered by protective coating.

It remains inert until it comes into contact with the feral cat, and while it’s harmless to the native animal, to the predator it’s highly deadly once ingested — via redwolf.newsvine.com

Meet the designer cats with wild blood / Vox

Bengals, Savannahs, and Toygers, explained.

By breeding house cats with wild animals, humans developed hybrid cats that look like little leopards. Bengal cats are a breed that was developed by breeding domestic cats with Asian Leopard Cats. The first American Bengal breeder is a woman named Jean Mill, but her work has continued through other breeders. We met one of those breeders, Anthony Hutcherson, when we went to film the cats at the Westminster Dog Show. Besides Bengals, we also saw another hybrid breed: Savannahs. Instead of Asian Leopard Cats, Savannahs were developed by breeding house cats with Servals. Unlike the other two breeds, the last breed we met, Toygers, are not hybrid cats. Breeder Judy Sugden created the breed by carefully breeding domestic cats with qualities that resemble wild tigers — via Youtube
