You’ve seen those photos of dogs snapped through catching a treat, with just the silliest faces? I see those and raise you: a tiger catching meatballs.

This is Kali, a Sumatran tigress at the Point Defiance Zoo & Aquarium in Tacoma.

"During an archaeological dig in a desert area north of Jerusalem 40 years ago, a seed was discovered which was determined to be in pristine condition but had obviously seen many a year.

Now, despite falling from its parent 1,000 years ago, it has grown into a mature tree, and botanists examining it believe it may be an extinct species that was used for medicinal purposes for thousands of years—even receiving a nod in the Bible.

Neither Israeli botanists, nor Dr. Sarah Sallon, a physician who founded the Louis L. Borick Natural Medicine Research Center at Hadassah University Medical Center in Jerusalem, could determine what species it was from simply from the seed covering. So they did what nature intended—they planted it.

Using a well-documented technique that saw 2,000-year-old date palm fruit pits germinate, Dr. Sallon soaked the seed in hormones, liquid fertilizer, and water, and then planted it in a pot of sterile seed; then waited.

Despite its genetic code being exposed to environmental stressors for over 1,000 years, the seed sprouted after 5 weeks. The shoot was protected by a caplike feature called an operculum. As the shoot grew, the operculum was shed—leaving something for the team to radiocarbon date. It narrowed down the age of the almost 10-centuries-old seed to between the years 993 an 1202.

Fast forward 14 years and the plant has become a 10-foot-tall tree. Dr. Sallon shared images of the tree, its bark, and its leaves with botanists around the world. One expert suggested it belonged to the genus Commiphora, found across the Arabian Peninsula and parts of Africa. A genetic analysis subsequently revealed this was the case, but a perfect match was lacking.

Pictured: The tree, now 14 years old.

Dr. Sallon and her team thought it was an extinct species known from history as Judean Balsam, but the best way to confirm that suspicion would be to have some aromatic traces similar to the resins of the myrrh tree to which it is related. However, no such fragrant compounds were detected.

Instead, the chemical analysis of the leaves identified a group of phytochemicals known as guggulterols which have been observed in a related species called Commiphora wightii that’s known to possess certain cancer-fighting properties in its resin.

A medicinal balm, the origin of which is not known, is mentioned in multiple historical texts including the Bible as ‘tsori,’ and rather than the fragrant Judean Balsam, it’s this tsori that Dr. Sallon and her team believe they have found.

They must wait until the tree, now 14 years old, produces flower or fruit to know for sure if it’s an extinct species, and if so, how to perhaps keep it alive.

Dr. Louise Colville, senior research leader in seed and stress biology at Royal Botanic Gardens, Kew, in London who wasn’t involved in the research, told CNN that it was a major accomplishment to grow a seed that old and possibly lead to a resurrection of this Biblical botanical.

“What’s surprising in this story is it was just a single seed and to be able to have one chance for that to germinate is extremely lucky,” she said.

“Working in a seed bank, seeing the potential for that extreme longevity gives us hope that banking and storing seeds that some at least will survive for very long periods of time.”"

Note: This is such a good demonstration of why seed banks are so important!! They give us such real and massive hope for deextinction and the revival of endangered species.

A study that just came out demonstrates that outdoor cats are known to prey on over two thousands species of wild animal, from mammals to birds to insects. That includes 347 species that are endangered, threatened or otherwise of concern, and they've been a key factor of the permanent extinction of over 60 species. And while cats may not always bring home what they catch, chances are if your cat is allowed to roam unsupervised outside, they're killing your local wildlife.

Why is this so important? Worldwide, wild animal populations have decreased in number by 69% in the past fifty years; that means that in my lifetime (born in 1978), the sheer number of wild animals in the world has been decreased by over half. Even "common" wild species are less numerous than before. While habitat population is the single biggest cause of species endangerment and extinction overall, outdoor and indoor/outdoor cats are a significant cause as well. In fact, they are the single biggest cause of human-caused mortality in wild birds.

Most importantly, it's very, very simple to fix this problem: keep your cats indoors, and spay and neuter them. If your cat is bored, they need more enrichment, and there are plenty of ways to make your home more exciting for them, from bringing home cardboard boxes for them to explore, to playing with them more often. If you want your cat to get some outdoor enrichment, leash train them (yes, it can be done!) If you have the space and resources, build them a catio where they can be safe from outdoor dangers like predators and cars, while also keeping local wildlife safe from them.

If you just give into their whining and pawing at the door, then they know that that's what they have to do to get their way; I know it's a tough transition, but it's worth it in the end for everyone involved. Cats are domesticated, which means they are not native anywhere in the world; there are exactly zero ecosystems in which they belong, save for the safety of your home. It is your responsibility to give them an enriching environment without taking the shortcut of letting them go wreak havoc outside.

getting emotional over footage of an amateur scuba diver interacting with a coelacanth. they are hunted by large deepwater predators, and here comes a large creature bearing the brightest lights it's ever seen, making strange noises, but it does not shy away. it hovers, calmly, as the diver reaches out and trails a hand down its back. im strongly against the anthropomorphizing of real life animals but the stupid emotional part of me loudly insists this is because it recognizes us, the alternating movements of its four paired limbs matching the diver's four paired limbs, & it is thinking, "hello, cousins, we missed you these 66 million years, it's so good to see you again. welcome back, welcome home."

text from porter robinson's "goodbye to a world"

every single animal in this comic is extinct. it's not too late for the ones that are left.

edit: thanks @mudcrabmassacre for the correction, smilodon fatalis did not in fact go extinct in 1023 AD. the actual prediction is around 10,000 years ago - I think i may have missed a zero or two.

Good News - June 15-21

Like these weekly compilations? Tip me at $Kaybarr1735! And if you tip me and give me a way to contact you, at the end of the month I'll send you a link to all of the articles I found but didn't use each week!

1. Victory for Same-Sex Marriage in Thailand

“Thailand’s Senate voted 130-4 today to pass a same-sex marriage bill that the lower house had approved by an overwhelming majority in March. This makes Thailand the first country in Southeast Asia, and the second in Asia, to recognize same-sex relationships. […] The Thai Marriage Equality Act […] will come into force 120 days after publication in the Royal Gazette. It will stand as an example of LGBT rights progress across the Asia-Pacific region and the world.”

2. One of world’s rarest cats no longer endangered

“[The Iberian lynx’s] population grew from 62 mature individuals in 2001 to 648 in 2022. While young and mature lynx combined now have an estimated population of more than 2,000, the IUCN reports. The increase is largely thanks to conservation efforts that have focused on increasing the abundance of its main food source - the also endangered wild rabbit, known as European rabbit. Programmes to free hundreds of captive lynxes and restoring scrublands and forests have also played an important role in ensuring the lynx is no longer endangered.”

3. Planning parenthood for incarcerated men

“[M]any incarcerated young men missed [sex-ed] classroom lessons due to truancy or incarceration. Their lack of knowledge about sexual health puts them at a lifelong disadvantage. De La Cruz [a health educator] will guide [incarcerated youths] in lessons about anatomy and pregnancy, birth control and sexually transmitted infections. He also explores healthy relationships and the pitfalls of toxic masculinity. […] Workshops cover healthy relationships, gender and sexuality, and sex trafficking.”

4. Peru puts endemic fog oasis under protection

“Lomas are unique ecosystems relying on marine fog that host rare and endemic plants and animal species. […] The Peruvian government has formally granted conservation status to the 6,449-hectare (16,000-acre) desert oasis site[….] The site, the first of its kind to become protected after more than 15 years of scientific and advocacy efforts, will help scientists understand climatic and marine cycles in the area[, … and] will be protected for future research and exploration for at least three decades.”

5. Religious groups are protecting Pride events — upending the LGBTQ+ vs. faith narrative

“In some cases, de-escalation teams stand as a physical barrier between protesters and event attendees. In other instances, they try to talk with protesters. The goal is generally to keep everyone safe. Leigh was learning that sometimes this didn’t mean acting as security, but doing actual outreach. That might mean making time and space to listen to hate speech. It might mean offering food or water. […] After undergoing Zoom trainings this spring, the members of some 120 faith organizations will fan out across more than 50 Pride events in 16 states to de-escalate the actions of extremist anti-LGBTQ+ hate groups.”

6. 25 years of research shows how to restore damaged rainforest

“For the first time, results from 25 years of work to rehabilitate fire-damaged and heavily logged rainforest are now being presented. The study fills a knowledge gap about the long-term effects of restoration and may become an important guide for future efforts to restore damaged ecosystems.”

7. Audubon and Grassroots Carbon Announce First-of-its-Kind Partnership to Reward Landowners for Improving Habitats for Birds while Building Healthy Soils

“Participating landowners can profit from additional soil carbon storage created through their regenerative land management practices. These practices restore grasslands, improve bird habits, build soil health and drive nature-based soil organic carbon drawdown through the healthy soils of farms and ranches. […] Additionally, regenerative land management practices improve habitats for birds. […] This partnership exemplifies how sustainable practices can drive positive environmental change while providing tangible economic benefits for landowners.”

8. Circular food systems found to dramatically reduce greenhouse gas emissions, require much less agricultural land

“Redesigning the European food system will reduce agricultural land by 44% while dramatically reducing greenhouse gas emissions from agriculture by 70%. This reduction is possible with the current consumption of animal protein. “Moreover, animals are recyclers in the system. They can recycle nutrients from human-inedible parts of the organic waste and by-products in the food system and convert them to valuable animal products," Simon says.”

9. Could Treating Injured Raptors Help Lift a Population? Researchers found the work of rehabbers can have long-lasting benefits

“[“Wildlife professionals”] tend to have a dismissive attitude toward addressing individual animal welfare,” [… but f]or most raptor species, they found, birds released after rehabilitation were about as likely to survive as wild birds. Those released birds can have even broader impacts on the population. Back in the wild, the birds mate and breed, raising hatchlings that grow up to mate and breed, too. When the researchers modeled the effects, they found most species would see at least some population-level benefits from returning raptors to the wild.”

10. Indigenous people in the Amazon are helping to build bridges & save primates

“Working together, the Reconecta Project and the Waimiri-Atroari Indigenous people build bridges that connect the forest canopy over the BR-174 road[….] In the first 10 months of monitoring, eight different species were documented — not only monkeys such as the golden-handed tamarin and the common squirrel monkey (Saimiri sciureus), but also kinkajous (Potos flavus), mouse opossums (Marmosops sp.), and opossums (Didelphis sp.).”

"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.”"

Ga'ga karisu, Saipan Reed-Warbler (Acrocephalus hiwae) is a critically endangered species found in the Northern Mariana Islands. Though few remain due to habitat loss, they fill the air with their rich melodic songs in those places where they can still hold on.

Their closest relative, the Nightingale Reed-Warbler of Guam, is extinct due to habitat loss and the invasive brown tree snake.

That's so cool! And they found a few of them, and they're now growing seedlings in greenhouses for eventual replanting!

Quercus tardifolia is a relic species leftover from when the climate was much cooler and wetter in the past, and can only really live in a few high-elevation spots in Texas. It's definitely still at risk of extinction due to increasing heat and drought caused by climate change, but the discovery means this species still has a chance.
