VIDEO: How Wolves Change Rivers

As we discussed in our gray wolf facts article, gray wolves are keystone predators. They help maintain a healthy ecosystem by preying upon weak animals, thereby strengthening the herd as a whole.

In this video, George Monbiot reveals how the reintroduction of wolves into Yellowstone National Park after a 70-year absence not only changed the ecosystem of the park, it also altered the physical landscape.

Amazing Close-Up Photos of Bees

The U.S. Geological Survey Bee Inventory and Monitoring Lab has been studying the decline of bees over the past ten years. According to Sam Droege, who heads the lab, there are 4,000 bee species in North America, but most people can’t identify the different species.

“We [needed] really high-definition pictures that people can drill into and say, ‘You know the pattern of the crosshatching between the pits on the skin of the upper part of the bee is really different than this one.’”

So Droege developed a system of taking high-definition photographs of the bees in order to document their specific features. Using a high-quality 60 mm macro lens and a device called a StackShot Rail, he takes a series of photos in increments where various parts of the bee are in focus. He later uses program called Zerene Stacker to combine the photos into a single, high-def photo all in focus.

Baby Rhino Makes His Public Debut

Newly-named Eastern black rhinoceros calf, King, made his public debut today at the Lincoln Park Zoo. The baby rhino, who already weighs in at 200 pounds, thrilled zoo-goers as he trotted out into the Harris Family Foundation Black Rhinoceros Exhibit, exploring the sights and scents. He and his mother Kapuki had been bonding behind the scenes since his birth on August 26.

In the wild, Eastern black rhinos are critically endangered due to poaching. It is estimated that there are only 5000 left in the wild in Africa.

“Breeding programs at zoos are of crucial importance to the survival of these remarkable animals, particularly as the numbers in the wild continue to dwindle,” said Lincoln Park Zoo Curator of Mammals Mark Kamhout. “King will serve as an excellent ambassador for his species.”

Endangered Black Rhino Calf Born at Lincoln Park Zoo

The Lincoln Park Zoo happily welcomed the birth of a critically-endangered black rhinoceros calf on August 26. The male calf weighed in at 60 pounds.

“Mother and baby are both doing wonderfully,” said Curator of Mammals Mark Kamhout. “The calf divides his time between nursing, following mom around, and napping, and that is exactly what a baby rhino should be doing.”

With only 5,000 black rhinos alive in the wild, the species is considered at high risk of extinction. They are threatened primarily by poachers, who kill the rhinos for their horns. In some cultures, black rhino horns are considered very valuable for medicinal purposes.

The Lincoln Park Zoo worked hard to conserve this species through the Rhinoceros Species Survival Plan, an initiative of the Association of Zoos and Aquariums (AZA).

Mother Kapuki and her calf will be bonding behind the scenes for the next couple of weeks.

“This birth is cause for great celebration here at Lincoln Park Zoo and has been much anticipated” said Kamhout. “The gestational period for rhinos is 15-16 months, and they have incredibly small windows for conception. Together with the zoo’s endocrinologists, we worked to pinpoint the exact window for Kapuki and Maku to get together for breeding. The whole zoo family is delighted at this successful outcome.”

Endangered Pond Turtles Released to the Wild

The Woodland Park Zoo and the Washington Department of Fish and Wildlife released over a hundred endangered western pond turtles to their native habitat in an effort to restore the population.

Western pond turtles once commonly inhabited the western coast of the United States. But several threats, including predation by the non-native bullfrog, disease, and habitat loss, put them on the bring of extinction since the early 90s.

In 1991, the Western Pond Turtle Recovery Project was established. Each year, recovery workers monitor adult female western pond turtles during the nesting season. They protect nesting sites with wire cages to prevent predators from eating the eggs. Then in the fall, the eggs and hatchlings are transported to the Woodland Park and Oregon Zoos where they can grow in safety.

“We return the turtles to their homes every summer once they reach a suitable size of about 2 ounces, a safeguard against the large mouths of bullfrogs,” explained Dr. Jennifer Pramuk, Woodland Park Zoo’s reptile curator.

Woodland Park Zoo has joined forces with Panthera to continue the battle to save tigers in the wild. The group will focus on saving tigers in Malaysia, where habitat loss and poachers have decimated the population. The ten year project will provide hands-on training and financial assistance to help save these tigers.

June 28th saw the birth of Chester, a yellow-backed duiker, at the Memphis Zoo. Duikers are a species of antelope found in Sub-Saharan Africa. Yellow-backed duikers are the largest and most abundant of all duiker species. They are threatened with extinction due to hunting for food and habitat loss.

Bella and Darwin, two female Galapagos tortoises, will be making their public debut at the Nashville Zoo on July 27. The pair are both 20 years old, and Galapagos tortoises can live up to 150 years. Bella weighs 280 lbs and Darwin weighs 200, but they aren’t done growing yet! Fully grown, they will weigh 350 lbs.

In addition to discussions on tigers, feedings, and face painting, proceeds from the tigress and cubs plush toys sold in the Tiger Lodge gift shop in the Jungala area will be donated to the SeaWorld & Busch Gardens Conservation Fund. On exhibit will be the endangered Malayan tiger cubs pictured.

Rare Zoo-Raised Turtles Released to Wild

The Lincoln Park Zoo in conjunction with the US Fish & Wildlife Service is working to repopulate prairie land with native wildlife.

Their most recent release was 18 ornate box turtle hatchlings in the Upper Mississippi River National Wildlife and Fish Refuge near Savanna, Illinois. The zoo is also recovering other prairie-dwelling wildlife including meadow jumping mice and smooth green snakes.

“Suitable habitat is being created, but many species have trouble accessing it due to fragmentation from roads and other physical barriers which makes re-colonization of restored sites improbable,” explained Allison Sacerdote-Velat, Ph.D. reintroduction biologist at Lincoln Park Zoo.

“These collaborative conservation partnerships are terrific because each agency brings a unique expertise. The zoo specializes in small population biology and animal care. We can successfully breed, hatch and care for these species until they are large and mature enough for release to the wild – a technique called ‘head-starting’ which gives them a greater chance of survival upon release.”
