Extinct Or Just Missing? Rediscovered Animal Species

Bat's Back.

A bat which was thought to be extinct in the UK has been found hibernating in a disused railway tunnel.

In 1992, the greater mouse-eared was declared extinct in the UK, but in 2002 a single male was found in a network of tunnels in West Sussex, where it has been known to hibernate for the last 20 years.

A second bat was found in those same tunnels earlier in January.

The Sussex Bat Group said the find was a "hugely important discovery".

"This demonstrates the importance of regular monitoring of bat colonies. We could have missed this highly significant find of the second greater mouse-eared bat in Britain," group spokesperson Sheila Wright said.

Would be good to hear that they eventually turn into a Colony. . . or, maybe that term should be changed to a 'Battery?'

The article doesn't mention whether the second bat is a girl but I hope so.

Not sure if this is the right place for this and I've never heard of "iterative evolution", The Aldabra White Throated Rail apparently went extinct and effecively re evolved!

["the evolutionary process"] Seems it was mainly due to their ability long ago, to wing-it to other islands where they managed to survive though in time - losing the ability to fly, simply because they didn't have the need to (lack of predators), and poor wing muscle development. So it sounds like in order for them to survive any threats into the future they will need mankind's involvement.
 

Officially extinct fish is alive and well, according to DNA analyses​

The houting, a fish species that lived in North Sea estuaries and is officially extinct, turns out to be alive and well. Researchers from the University of Amsterdam and the Natural History Museum London extracted DNA from multiple houtings conserved in the museum, up to 250+ years old. Next they compared the DNA of these museum fish with DNA from various currently occurring sibling species. The biologists found hardly any genetic difference between houting and a species called European whitefish. Since this species is still common, houting therefore isn't extinct.

We need to keep it around just so we can drop "Yellow-crested Helmetshrike" in conversations.

It might well be a good idea to do exactly that ~ drop it into conversations. . . see on 'Tun11's post (as above) and click on 'lost bird' link, and you'll see why.
Quote from the article: [Around the world, more than 130 species of birds, or about one percent, are considered “lost.” At least a decade has passed since each of these species were last confirmed by photographs, sound recordings, or physical documentation.] So a very worthwhile reason for 'dropping it in!' :bthumbup:

Javan Tiger May Not Be Extinct After All, DNA Analysis Of Hair Suggests​


Once declared extinct, a type of Indonesian tiger may still be around, recent DNA analysis has tentatively suggested. Much more research is needed to be certain, but conservationists say there is now a glimmer of hope the Javan tiger could still be out there, roaming the island’s forests.

The Javan tiger (Panthera tigris sondaica) was categorized as Extinct on the IUCN Red List back in 2008. Since then, there have been a handful of potential observations, each without substantiative evidence to back them up. However, in 2019, locals sighted what they thought was a Javan tiger near the village of Cipendeuy in the forest of South Sukabumi, West Java, alongside footprints and claw marks. They collected a single hair from a nearby fence.

Analysis of this hair points towards it belonging to a Javan tiger, although further research is needed to confirm its existence. “Whether the Javan tiger actually still occurs in the wild needs to be confirmed with further genetic and field studies,” the team concludes in their study.

Still, the prospect has stirred public interest, and even efforts among Indonesian conservationists to investigate whether this “extinct” big cat is indeed still alive and kicking.
