I teared up this morning when I heard this news. Such a loss.

I wonder if someone will float the idea of auctioning the right to shoot the two surviving rhinos to greedy alpha-sociopaths, with an 8-figure starting bid price: they get to be the indisputably über-dominant alpha-titan who killed the last of a species (which was doomed anyway), for the low price of 1/5 of a superyacht, which could be spent on saving other species.

It’s even worse:

One of the huge hurdles facing scientists is that the two remaining female northern white rhinos cannot gestate the next generation — one is sterile and the other is not physically capable of carrying a calf full term.

There used to be two at the San Diego Zoo Safari Park. I got to see them in 2010, though they both passed of natural causes since them. Here is a picture I took of Nola, a female, taking a nap.

This is sad to read. Lately the news about the environment has felt like watching a slow-motion train wreck -- the trajectory is clear, but the momentum feels irresistible.

Sorrowful news.

Surely this post needs to be edited to say "the last male northern white rhino". He isn't the last: one of the two females will be.

The end of the article has a slim ray of hope:
"But then, as far as their propagation is concerned, we are happy that at least we collected some sperm from him and the other males," Ngulu said.

One of the huge hurdles facing scientists is that the two remaining female northern white rhinos cannot gestate the next generation — one is sterile and the other is not physically capable of carrying a calf full term.

"So, natural reproduction cannot take place, artificial insemination is not possible, so the only other option that we have to have a pure northern white rhino baby is to retrieve or to do something we call ovum pick-up, collect eggs from the females," Ngulu said.

Those fertilized eggs would then be implanted in a southern white rhino, who would carry the calf to term. Taking eggs from a rhino, though, has never been done. If and when scientists take that risk, there's a chance that the females could perish — bringing the species to extinction.
Like I said, slim, but it's there.

On the Blue doesn't count. It's like Chatham House rules or something.

The problem with ovum collection as an idea is that the two females are Sudan's daughters and already quite inbred.

There's a concept called extinction debt that means the conditions for the species's extinction have already been met, it's not going to be able to reproduce as a viable population in the future, even if there are still some individuals hanging around. The Northern white rhino effectively went extinct years ago. We've just been waiting for the repo guys to come.

Heartbreaking. And so many more extinctions to come. Soon wild animals will be stories only, and nothing left to see for future generations.

Because the linked article did not mention it: Let's be clear, the extinction of these rhinos can be primarily attributed to believers in traditional Chinese medicine, which is threatening the extinction of numerous species, including tigers, black bears, pangolins, lions, and manta rays.

The market for these products extends far beyond China itself, but China is the largest market, and the Chinese government continues to do very little to curb the supply or demand within its borders.

This extinction is terrible, even more so because it was completely avoidable. And there will be more as long as millions of people believe that eating rhino horns, tiger penises, and lion bones will cure their impotence.

Yes this is firmly on believers in Chinese medicine not hunters. Chinese animal medicine is nothing but magical thinking and com artistry. It's one of the biggest threats to wildlife worldwide, many other species are also at risk. China needs to do something and soon.

Wow, if you don't want to be simultaneously enraged and sickened, stay away from the wikipedia entry on animal sources for traditional Chinese medicine. Suffice it to say that the abuse of animals goes way beyond just unsustainable hunting.

Unfortunately Chinese wikipedia is still blocked entirely in China.

The really crazy bit about the Chinese impotence angle is that we have plenty of very effective, cheap, easily accessible drugs that will do the job for you. Aside from limited placebo effects I highly doubt that rhino horn is helpful in giving you a stiffy.

But like many things in China, appearance can trump reality... the super expensive last dose from an extinct species is the ultimate veblen good.

This made me cry. Explaining to people how female rhinos become unable to reproduce if they aren’t mating regularly has been something I’ve done a lot in the last few days. Explaining that with megafauna it really is necessary to have natural mating, that assisted reproduction probably won’t work. The surviving females are a daughter and grand-daughter. They refused to mate with him.

My lovely sister works for Save the Rhino in the UK, and I asked her about the sperm they collected before poor Sudan died, she said that to combine it with ovum collection costs millions of pounds and with the difficult fundraising they wonder whether this money would be best spent here or on other endangered species of rhinos. Such sad news.

Wired has a write-up on a plan to use revive the species:
In what [Professor Thomas Hildebrandt] calls a race against time, he plans to deploy IVF techniques and fly to Kenya to collect eggs from the ageing females, Fatu and Najin, in May or June via a method called ovum pick-up. The incubated eggs will be flown from Ol Pejeta via Nairobi to Zurich and then onto Cremona in Italy where Cesare Galli, who specialises in assisted reproduction of large animals, will mature and fertilise them and develop embryos suitable for transfer. They will then be implanted in southern white rhino surrogates – neither Fatu nor Najin are able to carry calves themselves – in the hope they will carry them to full term.

“It’s very foreseeable in the near future that we’ll have offspring,” Hildebrandt said.

Even if Hildebrandt and his team manage to produce a lot of offspring from the two females using IVF with the frozen semen they have, they will be unable to achieve the necessary biological variety to create a long-term sustainable population, he said.

Which is where stem cell research is crucial. Within the next three to five years the institute should be able to use skin cell samples taken in 2014 from Sudan and other northern white rhinos, add genes to them in order to turn them into stem-cells, and encourage them to become eggs. These would be fertilised with the sperm samples stored by Hildebrandt to create test-tube rhinos which southern white rhino surrogates would, it is hoped, carry to term, producing genetically-variable offspring.

The brains behind the stem cell technology are those of Katsuhiko Hayashi who in 2016 made headlines after he successfully used mice stem cells to grow eggs which produced healthy offspring.

“This technology will provides us with the missing link,” Hildebrandt said.
Someone is willing to spend the money to potentially undo some of the past disasters of people.
