"Once thought to be extinct, black-footed ferrets are the only ferret native to North America, and are making a comeback, thanks to the tireless efforts of conservationists.

Captive breeding, habitat restoration, and wildlife reintegration have all played a major role in bringing populations into the hundreds after near total extinction.

But one other key development has been genetic cloning.

In April [2024], the United States Fish and Wildlife Service announced the cloning of two black-footed ferrets from preserved tissue samples, the second and third ferret clones in history, following the birth of the first clone in December 2020. 

Cloning is a tactic to preserve the health of species, as all living black-footed ferrets come from just seven wild-caught descendants.  This means their genetic diversity is extremely limited and opens them up to greater risks of disease and genetic abnormalities. 

Now, a new breakthrough has been made.

Antonia, a black-footed ferret cloned from the DNA of a ferret that lived in the 1980s has successfully birthed two healthy kits of her own: Sibert and Red Cloud.

These babies mark the first successful live births from a cloned endangered species — and is a milestone for the country’s ferret recovery program.

The kits are now three months old, and mother Antonia is helping to raise them — and expand their gene pool.

In fact, Antonia’s offspring have three times the genetic diversity of any other living ferrets that have come from the original seven ancestors.

Researchers believe that expanded genetic diversity could help grow the ferrets’ population and help prime them to recover from ongoing diseases that have been massively detrimental to the species, including sylvatic plague and canine distemper. 

“The successful breeding and subsequent birth of Antonia's kits marks a major milestone in endangered species conservation,” said Paul Marinari, senior curator at the Smithsonian’s National Zoo and Conservation Biology Institute. 

“The many partners in the Black-footed Ferret Recovery Program continue their innovative and inspirational efforts to save this species and be a model for other conservation programs across the globe.”

Antonia actually gave birth to three kits, after mating with Urchin, a 3-year-old male ferret. One of the three kits passed away shortly after birth, but one male and one female are in good health and meeting developmental milestones, according to the Smithsonian.

Mom and babies will remain at the facility for further research, with no plans to release them into the wild.

According to the Colorado Sun, another cloned ferret, Noreen, is also a potential mom in the cloning-breeding program. The original cloned ferret, Elizabeth Ann, is doing well at the recovery program in Colorado, but does not have the capabilities to breed. 

Antonia, who was cloned using the DNA of a black-footed ferret named Willa, has now solidified Willa’s place as the eighth founding ancestor of all current living ferrets.

“By doing this, we’ve actually added an eighth founder,” said Tina Jackson, black-footed ferret recovery coordinator for the U.S. Fish and Wildlife Service, in an interview with the Colorado Sun. 

“And in some ways that may not sound like a lot, but in this genetic world, that is huge.”

Along with the USFWS and Smithsonian, conservation organization Revive & Restore has also enabled the use of biotechnologies in conservation practice. Co-founder and executive director Ryan Phelan is thrilled to welcome these two new kits to the black-footed ferret family.

“For the first time, we can definitively say that cloning contributed meaningful genetic variation back into a breeding population,” he said in a statement.

“As these kits move forward in the breeding program, the impact of this work will multiply, building a more robust and resilient population over time.”"

Endangered Species Sightings from This Year

This is thought to be the first time in over 20 years that a blue whale was spotted off the Coast of Massachusetts.

I highly recommend watching the video and listening to the reaction of the people on the whale watching boat--the cheers and emotion in some of their voices, especially the woman saying "I'm trying not to" when someone jokingly tells her not to cry.

This is the first time ever that a mother clouded leopard with two cubs has been spotted on a game cam!

"After being considered regionally extinct for over a century, giant anteaters have been spotted roaming once again in Brazil's Rio Grande do Sul state. Scientists have concluded these returned natives ventured over from Argentina's Ibera Park, where conservationists have released around 110 rescued and captive-bred anteaters since 2007."

Over 100 years and the anteaters are finally coming home!

During my internship, I saw another strange fellow. If you like the neck flexibility of the European wryneck you sure gonna love the Little bittern (Ixobrychus minutus). This bird is in the heron family (Ardeidae) but loves to shrink itself. But be warned ! They know where your eyes are and can launch their neck and beak real fast ! One tried to attack me while I was checking its ring and I was lucky to be just 10 cm too far. Despite this vicious attack I love this funny bird and he was quite easy to untangle and to ring. With colleagues, we nicknamed it the "Accordion of death"

🦇Museum Curator of Mammalogy Angelo Soto-Centeno shares updates from his recent expedition to Puerto Rico, where he and a team of local and international researchers led a paleontological excavation and bat diversity inventory. The aim of this work was to explore new locations to examine the present, or living, and past, or fossil, communities of bats and identify species that have become extinct in recent times.

They found three species of extinct bats that were lost in the last 4,000 to 1,600 years—including insectivore and nectarivore bats!

This is a pretty big deal. When I was a kid in the 1980s, this was one of the most endangered species in the world. It had been declared extinct in 1979, but two years later a small population was discovered in Wyoming. These became the basis for a breeding and reintroduction program, and today there are a few hundred in the wild with more in captive breeding programs.

The challenge with working with such a small captive population is that you only have so many adult female ferrets that can be having kits at any given time. While cloning is more resource-intensive than simply raising a ferret born in captivity, it adds another individual to the breeding pool. If cloning can be streamlined, it could help increase the number of breeding adult ferrets more quickly than through natural means alone.

In this case, one of the first cloned black-footed ferrets has not only made it to adulthood but has successfully given birth to two kits which wouldn't have existed otherwise. Because she was cloned from the cells of a ferret that died in the 1980s, she was able to reintroduce genetic diversity in a species that has suffered a severe population bottleneck. While it remains to be seen whether the kits survive to adulthood--a challenge any young ferret faces--this is a very promising sign.

We can't rely on cloning alone to save this species, though. The systematic destruction of prairie habitats for agriculture and other development, the subsequent loss of prey populations, the introduction of canine distemper from domestic dogs, and secondary poisoning from poisoned prairie dogs and other prey, all have contributed to the precipitous decline of this charismatic little mustelid. By preserving and restoring prairie habitats and their biodiversity, preventing the poisoning of prey, and controlling canine distemper vectors, we can give both birthed and cloned black-footed ferrets a better chance of reestablishing their species in their historic range.

Conservation efforts directed towards just 0.7% of the world's land mass could help protect one third of the world's threatened and unique tetrapod (four-limbed vertebrate) species, new research by Imperial College London, On the Edge, and ZSL has shown. The study, led by researchers at Imperial College London and published this week in Nature Communications, finds that large gains in conservation are possible by focusing on areas home to exceptional biodiversity and species with high levels of evolutionary distinctiveness and global endangerment.

"In 2021, scientists in Guelph, Ontario set out to accomplish something that had never been done before: open a lab specifically designed for raising bumble bees in captivity. 

Now, three years later, the scientists at the Bumble Bee Conservation Lab are celebrating a huge milestone. Over the course of 2024, they successfully pulled off what was once deemed impossible and raised a generation of yellow-banded bumble bees. 

The Bumble Bee Conservation Lab, which operates under the nonprofit Wildlife Preservation Canada, is the culmination of a decade-long mission to save the bee species, which is listed as endangered under the Xerces Society for Invertebrate Conservation...

Although the efforts have been in motion for over a decade, the lab itself is a recent development that has rapidly accelerated conservation efforts. 

For bee scientists, the urgency was necessary. 

“We could see the major declines happening rapidly in Canada’s native bumble bees and knew we had to act, not just talk about the problem, but do something practical and immediate,” Woolaver said. 

Yellow-banded bumble bees, which live in southern Canada and across a huge swatch of the United States, were once a common species.

However, like many other bee species, their populations declined sharply in the mid-1990s from a litany of threats, including pathogens, pesticides, and dramatic habitat loss. 

Since the turn of the century, scientists have plunged in to give bees a helping hand. But it was only in the last decade that Woolaver and his team “identified a major gap” in bumble bee conservation and set out to solve it. 

“No one knew how to breed threatened species in captivity,” he explained. “This is critically important if assurance populations are needed to keep a species from going extinct and to assist with future reintroductions.”

To start their experiment, scientists hand-selected wild queen bees throughout Ontario and brought them to the temperature-controlled lab, where they were “treated like queens” and fed tiny balls of nectar and pollen. 

Then, with the help of Ontario’s African Lion Safari theme park, the queens were brought out to small, outdoor enclosures and paired with other bees with the hope that mating would occur. 

For some pairs, they had to play around with different environments to “set the mood,” swapping out spacious flight cages for cozier colony boxes. 

And it worked. 

“The two biggest success stories of 2024 were that we successfully bred our focal species, yellow-banded bumble bees, through their entire lifecycle for the first time,” Woolaver said. 

“[And] the first successful overwintering of yellow-banded bumble bees last winter allowed us to establish our first lab generation, doubling our mating successes and significantly increasing the number of young queens for overwintering to wake early spring and start their own colonies for future generations and future reintroductions.”

Although the first-of-its-kind experiment required careful planning, consideration, resources, and a decade of research, Woolaver hopes that their efforts inspire others to help bees in backyards across North America. 

“Be aware that our native bumble bees really are in serious decline,” Woolaver noted, “so when cottagers see bumble bees pollinating plants in their gardens, they really are seeing something special.”"

I need you all to appreciate how crazy it is to have watched the scimitar horned oryx go from a poster child for "it only exists in zoos" to merely endangered (not even critically endangered!) over my lifetime.

So many heroic people contributed ridiculous amounts of time and effort to make this captive breeding and reintroduction effort a success.

How Non-Native Plants Are Contributing to a Global Insect Decline

The impact of introduced plants on native biodiversity has emerged as a hot-button issue in ecology. But recent research provides new evidence that the displacement of native plant communities is a key cause of a collapse in insect populations and is affecting birds as well...

European wryneck (Jynx torquilla) got its name from the behaviour of its youngs. They nest in tree-holes and when a predator tries to come near the babies move their head to mimic a snake. They also ruffle their head-feathers to push further the snake impersonation !

This mimicry added to their bark-like feathers makes them one of the most weird impressive bird I saw during my internship !
